Gwen Harwood Essay Essay Example

Gwen Harwood Essay Paper Opportunities for an individual to develop understanding of themselves stem from the experiences attained on their journey through life. The elements which contribute to life are explored throughout Gwen Harwood’s poems, At Mornington and Mother Who Gave Me Life, where the recollection of various events are presented as influences on the individual’s perception of the continuity of life. Both poems examine the connections between people and death in relation to personal connections with the persona’s father or mother. By encompassing aspects of human nature and life’s journey, Harwood addresses memories and relationships which contribute to one’s awareness of life. Memories and meandering thoughts, related to personal experiences, are explored throughout At Mornington where the persona shifts between the past and present and dreams and reality. This is similar to Father and Child where Barn Owl is set in past test and Nightfall is set in the present, symbolic of appreciation and understanding of the complexities of life which the child learns. At Mornington opens with an evocation of an event from the persona’s childhood which establishes the temporary and ever changing nature of human life. Reflected through the shifts between past and present tense, the persona is attempting to use past experiences in order to appreciate the present and accept the future. The poem provides a reflective and personal point of view accompanied by the recurring motif of water which symbolises the persona’s transition from childhood to the acceptance of the inevitability of death.

The action of the pumpkins is described as â€Å"a parable of myself† which allows the persona to reflect on the meaning and quality of her own life and existence. The metaphor between the pumpkin vine and the persona suggests that like the pumpkin, human life also ripens and matures before coming to a closure and returning to the earth. Supported by the phrase â€Å"candlelight for eyesight,† the reader is made aware of the transience of life that the persona has grown to accept and understand. In Father and Child, as the persona moves on from childhood, her father becomes elderly and is entertained by simple things in nature, â€Å"birds, flowers, shivery-grass. † These symbols of nature remind the persona of the inconsistency of life and the certainty of death, â€Å"sunset exalts its known symbols of transience,† where sunset represents time. Both poems are indicative of the impermanence of life and that the persona has managed to mature and grow beyond the initial fearlessness of childhood moving onto a sophisticated understanding of death. The connection between life and death is expressed in a different way through Mother Who Gave Me Life, a poem of mourning for the dead. The poem can be seen as a personal farewell to the persona’s mother where the dominant images of the poem show evolution and the passing of time. Father and Child also demonstrates the passing of time as the persona moves from the innocence of childhood to the sadness of her father’s advancing age and inevitable passing. In Mother Who Gave Me Life, the reference to Halley’s Comet, which appears only once every seventy-six years, tells the reader that the mother was unable to see it once more before surrendering to death. The direct speech of the Sister is reported without the use of quotation marks as in, â€Å"When she died she was folding a little towel. † This provides readers with the knowledge that the mother addressed in the poem is dead. Without quotation marks, the flow of the poem is maintained and is therefore more easily absorbed into the texture of the poem. The parallel image of the â€Å"fabric of marvels† being reduced to the â€Å"little towel† raises the notion that whilst death may have brought a physical end to the persona’s mother’s life she remains a marvel of creation as the persona’s memories of her live on. The poem ends with the ‘fine linen’ recalling the memories of a typical childhood scene where the persona’s mother is calling for her to have dinner â€Å"as darkness falls on my father’s house. † This biblical reference to the House of the Lord, combined with the coming of darkness, reminds the reader of the inevitable ending of life and the respective movement into heaven. As the second section of Father and Child draws to a close, it is evident that the persona has grown to understand that she has limited time left with her father. The significance of Nightfall as the title of the second section, when considering the daybreak setting of Barn Owl, reinforces this. Sunrise symbolises youth whilst nightfall, in comparison, suggests an ending which implies death, a concept that the adult persona is beginning to acknowledge it as part of life. A particular instance in life can conjure different memories of the past as in At Mornington where the persona is drawn into recollections of childhood experiences with her father while standing by the graveside of her friend’s parents. A positive image of the father and child relationship is conveyed throughout the poem as in, â€Å"secure in my father’s arms. † This image conveys safety, comfort and protection which assists the persona in moving on and accepting the cycle of life. It is the security which stems from this relationship that enables the persona to mature from the perceptions and thoughts maintained as a child. Insight into the relationship between the persona, as both child and adult, with her father is also demonstrated in Father and Child. The dominance of the father is suggested through his imperative tone, â€Å"End what you have begun. † Despite the power-play in their relationship, there is still a sense of closeness, â€Å"I leaned my head upon my father’s arms. † This connection has enabled the persona to mature and grow through experiences. This personal relationship is also evident in Mother Who Gave Me Life where the imagery of light shows the persona realises the importance of her mother as she walks â€Å"in the light of the living. † This suggests that the persona is able to walk amongst the living due to her mother. The affirming experiences and enlightenment provided by this relationship enables the persona to see the life-giving role of women as part of the cycle of life. All the poems comment on an individual’s relationship with their mother or father which is essential in maturing and evolving as an individual. The relationships conveyed enable the persona to gain an understanding of life whilst considering its value and accepting its cycle. Ultimately, the exploration of memory and relationships with the persona and their father or mother enables an individual to comprehend human nature and the links between life and death. Throughout the poems At Mornington and Mother Who Gave Me Life, Harwood shows the reader, through memories and comparisons, different aspects of life which contribute to what it means to be human.

Britain in WWI essays

Britain in WWI essays Britain, as a country of wealth, has proven itself on several occasions to be strong and powerful. It has created this reputation by being a world leader and one of the worlds largest industrial powers. Through morals, industrial revolution, and its Navy, Britain has been able to create a spectacular reputation which allowed it to align with others for protection and support, which in turn made its country the strongest it possibly could. The industrial revolution is what made Britain what it is today, although, it was WWI that brought the British Empire to the peak of its expansion. Imperial contributions had considerably strengthened the British war effort, and victory brought Britain mandates over new territories such as Palestine, Iraq, and Germany territories in Africa. Britain was a major industrial country in the early industrial revolution, but the only problem was that their empire was scattered through out the world, where as Frances empire was mainly based in the desolate reach of north and northwest Africa. Their industrial power was created in respect to the fact that they manufactured many goods, railroads, ships, heavy metals and other products. Their trading industry also contributed to this. Because they were over confident, Britain ended up being slower to engage in scientific research. Britain was becoming a very wealthy country because their machinery was either being exported or copied. The money, which the country was earning, helped to open new factories, which created many new jobs, supporting many more citizens. Money was also used to build railroads in Europe and the U.S. Britain quickly became the worlds greatest trader, and soon enough London was named the financial capital of the world right through 1914. In order to remain on top, Britain continued to invest their money. Investing led the country to imperialism and colonies. The country wanted colonies because t...

Revenge Essay Example | Topics and Well Written Essays - 750 words

Revenge - Essay Example The first article found on the website field-of –themes presents the historical and social framework that explains why revenge is a common theme in Elizabethan plays. According to the article, most Elizabethan plays are highly influenced by the Greeks. Seneca, the Roman playwright, played a great role in injecting the theme of revenge in Roman theater. However, revenge as a theme ( like in Hamlet) has its own formula : In all revenge tragedies first and foremost, a crime is committed and for various reasons laws and justice cannot punish the crime so the individual who is the main character, goes through with the revenge in spite of everything†¦ Other features that were typical were the appearance of a ghost, to get the revenger to go through with the deed. The revenger also usually had a very close relationship with the audience through soliloquies and asides. The original crime that will eventually be avenged is nearly always sexual or violent or both. The crime has been committed against a family member of the revenger. (field-of-themes.com) Another interesting article about revenge in Hamlet was written by Jennifer Alpeche in 2007. Hers was an insightful article that asserts the anguish that Hamlet must go through in order to exact his revenge. It must be remembered that Hamlet almost lost his mind when he encountered his father’s ghost. All the while, people around him suspected that he was madly in love with Ophelia which was partially true. However, it was Hamlet’s contemplative disposition that made him mad upon knowing the truth. To quote: In this scene, Hamlet is still contemplating about suicide. However, it is important to realize that Hamlet is besieged emotionally and psychologically by tough choices he has to make ever since he learned of his father’s death. Hamlet is torn between logic and religion in coming up with a decision. Apparently, morals cannot help him anymore to undo what Claudius has done. Philosophy is not

Long Paper - Essay Example This implies that the world should not be concerned with reducing consumption but reducing wastage since there are adequate resources for all people. Reduction of wastage can be accomplished through saving and recycling. While wastage can be found in almost all societal aspects, the most common forms include energy wastage and water wastage. Energy wastage can be attributed to lack of efficiency, using gas-guzzlers, and other practices that people may consider irrelevant such as leaving the water running while brushing the teeth. Although people may think that they are using the resources as they should, they may be wasting and still not realize it. According to statistical data, more than half of the energy produced is wasted through inefficiency and the fuel guzzling (Natural Resources Defense Council). The power plants also lead to high levels of power wastage. According to statistical data, power plants convert a mere 30% of the overall energy input into operational electricity. This implies that almost 70% of the fuel energy is wasted during the beginning of the power production process (WWF). These companies can improve the ir efficiency if they were willing to commit more financial resources into the power production process. This process can be improved if these companies could combine both power and heat production. These companies insist on using high heat production methods and situating these plants away from where people live. If this could be improved, there could be more than enough energy for usage in industries and homes and the call for reduction of consumption would not be relevant. The automobile industry is the other high-energy wastage sector in the society. An average automobile emits an approximated three times its weight in carbon dioxide annually. A vehicle with a consumption rate of approximately 7.8 liters in every 100 km travelling 10,000 miles annually would emit an

The art is lovers in a cafa the photographer is Brassai Research Paper

The art is lovers in a cafa the photographer is Brassai - Research Paper Example Usually, the photographers tend to focus on photographic realism that portrays harsh realities. This picture creates a connection between photographer and the subjects. This technique makes the picture more sophisticated. Brassaà ¯ considered Henri de Toulouse-Lautrec as his influence (Janson and Janson, 2004). The interesting thing about this picture is that, even though, the man has his back to the camera the photographer has been able to capture his eyes. The mirror reflection gives the picture more meaning. The way he is looking at his lover is full of love and romance. The woman is smiling, and both of them seem to be in love with each other. Kissing or fondling is a very natural act, but the photographer has highlighted it and captured it in a timeless medium. The picture is black and white, and there is hardly any posing. Both the subjects appear to be in the moment. Brassaà ¯ used capture the beauty of streets, frogs and rain in the garden at night (Sayag, 2000). He was fascinated by the nightlife. This time is also associated with romance and lovemaking. Cafà ©s are also usually filled with people and couples at this time. His photographs are in black and white color that resonates with the nighttime. The picture under discussion is black and white in color, which makes the pictures traditional. The lovers are seated inside a booth and about to embrace each other. The man is leaning in for the kiss; he is holding his prize with both his arms. The woman brushes her hair to reveal her face to make it accessible for her man. Her chin is lifted up, and her eyes are locked in with the mans eyes as she welcomes every move of him. The audience in this photograph is the teacups and the table. The subjects are completely ignoring what is going on around them. They are immersed in the magic of love. The onlooker can witness this magic moment from three angles. They can get a glimpse of what is in the reality. But a more

Open Source vs Closed Source Systems

Open Source vs Closed Source Systems INTRODUCTION For many years, proprietary software has been the dominating business approach used by the commercial software firms. Industry giants like Microsoft proved this strategy to be successful, building their multibillion dollar empires based on the proprietary software platform. Over the past decade, a new business approach called open source model which involves contributors from around the globe to create, share and distribute software code for free had come into practice (Pal, N Madanmohan, TR., 2002). Although the roots to this practice of sharing code evolved since early 60s, the widespread usage of internet and the technology developments in past two decades opened new opportunities for open source projects (CNET news, 1998). A number of Open Source Software (OSS) products such as Apache web server, BIND and SendMail have dominated their product categories ever since then (Pal, N Madanmohan, TR., 2002). In the past decade, several researchers (Wheeler, DA., 2007; Mockus, et al., 2000) have taken interest in studying how open source can be applied to modern business strategies. However, a concern exists that in this area of study that there is no substantial evidence that the practices followed are effective in the business environment (Bitzer Schrà ¶der, 2004). For economists like Lerner Tirole (2000), the altruism shown by commercial companies and programmers involved in an open source software project is surprising. They stated altruism hasnt played a major role in any other industry than software. Several others like Freeman Rogers (2008) and Goetz (2003) contradict this statement by illustrating altruism exist in any industry provided there is proper exposure of the problem towards the contributing community. But most of the researches surrounding open source model considered software industry as the base for their studies. 1.0 SCOPE OF THE PROJECT 1.1 Objective This project work focuses on the study of the Open Source ecosystem (Android) how it differs from Closed source sustems such as those surrounding the iPhone. This project includes the study of the Android Market, (online mobile application store for Android users) application developers, and which factors developers consider for selecting a platform for application development. To understand business strategy development trends across Android and iPhone platforms, we compared the Android market with the iPhone App Store, the leading application store in current mobile market. Apple launched an online application marketplace called the â€Å"iPhone App Store† before launching iPhone 3G. Currently, this store has more than 195,000 applications. To match or surpass the success of iPhone App Store, Apple rivals such as Google and Blackberry introduced their own application downloading stores called â€Å"Android Market† and â€Å"Blackberry App World† respectively. T he Android Market is similar to the iPhone App Store or to any other application store; it boasts a catalog of applications,  services and tools available for the user to purchase download and use. Today, the Android Market also has around 49,000 applications. Thus, the comparison between iPhone and Android application stores will help explain the new challenges faced by these two application stores, and also the demand for these stores in the near future. This study will help understand why Android choose Open Source System and why Apple doesnt, what determines their success, which large companies are directly involved in developing applications for Android, and which factors they consider for developing an application. 1.2 Experimental Procedures This project is based on a semi-automatically collected application database and   surveys to obtain necessary information for proving the hypothesis. (A) Website Data Firstly, application data were collected semi-automatically from the Android Market and iPhone App Store (iTunes store) and other mobile applications related websites, for e.g., Androlib.com, iPhoneapplicationlist.com. This gathered application database includes a list of the application categories on both platforms, number of applications in each category, and application information for the selected categories. (B) Interview Data Next, we interviewed mobile application developers to understand and know their views about Android/iPhone platforms and the ecosystem. To get in touch with mobile application developers, we attended the mobile conferences where they gather to share their views. (C) Survey Data Lastly, all the relevant facts about application developers from the interview data helped us prepare a survey. This web-based survey was prepared and conducted using Survey Monkey. 1.3 Resources Utilized The main resources used during this project were our industrial advisor, our academic reader, Android and iPhone application database, interviews and surveys from mobile application developers. 2.0 LITERATURE REVIEW 2.1 Introduction of Literature Review In order to achieve success in project implementation, the first step is to research and find information already available. During research, we found many articles related to our topic. This paper is based on the content from these articles. We have divided this section in four main areas: Overview of the Open Source Operating Systems (Android). Overview of the Closed Source Operating Systems (Apple IOS). Fundamentals behind the Open Source Platform. Introduction to the Smartphone. 2.2 Overview of the Open Source Operating Systems (Android). Google has achieved something remarkable with its open-source Android operating system. SinceApples iPhonerevolutionised thesmartphonein June 2007, bringing touchscreens and a beautiful user experience to the masses, its been without a rival. Sure, theres a small legion of BlackBerry fans, and a few Nokia die-hards, but the critical consensus up until about a year ago was that the iPhones achievements were peerless. EnterAndroid. The free, open-source mobile operating system was introduced to consumers with theHTC Dream(also known as theT-Mobile G1) in late 2008, but didnt start gaining steam until the release of theHTC Heroin July 2009. The Hero, armed with a custom user interface called Sense that HTC built in-house, gained rave reviews for its high-end specs and faultless user experience, and appeared on many critics lists of the best gadgets of 2009. The whispers began: Had Google managed to create a platform that genuinely rivalled the iPhone for the best smartphone experience around? This success is starting to show in the numbers. In February 2010, Google announced that more than 60,000 phones with Android on were shipping each day. The Android App Market is also booming, housing more than 30,000 downloadable applications in March 2010, although thats still comparably small when set beside the 185,000 or so Apple has in its App Store. But where once companies had to have an iPhone app, its now understood that they need to offer both an iPhone and an Android variant. Manufacturers havent let the opportunity pass them by, either. At the time of writing, there are around 35 mobile phones, five tablet PCs, three e-book readers and a netbook available that come with Android installed a total of about 43 devices. But thats nothing compared to the amount of gadgets that are purportedly in the works. If you tot up the rumours, statements of intent, leaked documents and roadmapped products from manufacturers, you can add at least another 15 smartphones, 19 tablet PCs, two e-book readers and three more netbooks to the pile. When you combine the totals, you arrive at a figure of at least 82 Android devices either released or in development. The platform has received four major updates since the HTC Dream launched with Android 1.0. Version 1.5 brought camcorder functionality and the ability to use homescreen widgets. Version 1.6 added voice search and a better Android App Market. Then version 2.0 revamped the user interface, added new, larger screen sizes, as well as navigation support in Google Maps. The latest update is version 2.1, which debuted on theNexus One a handset built by HTC but to specifications dictated by Google itself. Android 2.1 brings additional homescreens, animated wallpapers and the ability to use voice recognition to type in all text fields very useful if youre in a situation where you cant use an on-screen keypad, such as when driving. Other devices are starting to appear with version 2.1 as well the Motorola Droid, known as theMilestone in Europe, recently received an update to 2.1, and HTCs forthcoming Legend and Desire handsets come with it installed. Oldhardware=nonewtricks However, the new features available in 2.1 come with increased demand on the relatively weak processors found in most smartphones, particularly in the earlier Android devices. As a result, some handsets cant run later versions of Android at satisfactory speed. Even in those that can, manufacturers have been exceptionally slow at rolling out updates to their device owners, with HTC still not having delivered any update above 1.5 for its Hero at the time of writing. Its difficult to fault Google for wanting to update its core platform as fast as it can. The problem is that its going so fast that manufacturers cant roll out updates to their own software at a speed to match. The upshot for users is that early Android adopters are stuck on two-year contracts looking mournfully at all the fun that new device owners can get, with no knowledge as to whether theyll eventually have access to the new features themselves. This isnt anything new in most cases other manufacturers dont grant older gadget owners access to new features but its tough on Android users in particular because the pace of the updates is so fast. A phone can be out-of-date within months of its release, and in some cases handsets are still arriving with Android version 1.6 installed. App developers suffer, too. Many of Googles home-grown applications Maps, Earth, Goggles and Gesture Search were initially only released for the 2.0 and 2.1 platforms. Some have since gained backwards compatibility to 1.6, but HTC Hero owners, running 1.5, still cant use them. App developers have a tough choice to make: support as wide a range of phones as possible, or offer an app with superior features, but only to those running the latest Android builds. Situationnormal: Allforkedup So what can Google do about the problem? The company is stuck with four slightly different variants of its platform in the wild, and its got a splintered marketplace where one Android user cant necessarily access the same apps that another can, and its confusing and frustrating for end users. The obvious way ahead is to try and force manufacturers to update the software on their devices. Any device running 1.5 should be able to cope with 1.6, and a 2.0 device will manage 2.1. While that still leaves the problem of devices that cant quite cope with the most recent updates, Google should be able to merge its four shards into two a set of 1.6 devices and a set of 2.1 devices simplifying the situation somewhat. However, that relies on the goodwill and resources of a diverse set of companies, and some of those will only have dipped a toe into the waters of Android, meaning that they might be less keen to start devoting significant staff time to mucking around with operating system updates. So Googles got another trick up its sleeve. Recent rumours suggest that the company, in the upcoming version 2.2 update, is planning to de-couple the various applications that run on the device from the operating system itself. The browser, email apps, contacts, input methods and various other components will be downloadable and, crucially, updatable through the Android market rather than needing to wait for a full OS update to be upgraded. When Google wants to update the Gmail app, it can just push a market update, rather than forcing customers to wait for HTC, Dell, Samsung or other manufacturers to approve it. If Google fails to unify the Android platform, a future looms where Android is stuck in a series of ghettoes, with no guarantee that one Android user will be able to run the same apps as another unless they buy a new device every six months. Thats good news for manufacturers, but very bad news for Google and for consumers. If Google manages the transition successfully however, then a unified (or at least consolidated) platform could be easily updated by both Google and phone-makers, depending on whether the update is a critical security issue or a new feature in an application. Time is pressing. The fate of Android rests on what Google does over the summer of 2010. Will the platform fall by the wayside, or will it instead grow to be the Windows of smartphones, carefully balancing openness to app developers with a superior user experience and mass-market appeal? On past form, it seems foolish to bet against Google. Let us also look at the SORT analysis for android: Being a self declared Google and Android fanboy, Im constantly reading and studying about cloud computing and the mobile marketplace whenever I have the opportunity. Ive even begun the very first steps of beginning to learn programming Java for the Android platform, although this is a ‘free time endeavor which is going to take quite some time for me to get even the basic level of proficiency achieved. 2.2.1 SWOT Analyses for GOOGLE ANDROID But one area where I feel comfortable in discussion and analysis is in the business realm, which is why I decided to do a basic SWOT analysis for Google Android. It is a tool used in strategic planning to evaluateStrengths,Weaknesses,Opportunities, andThreats involved in a project or business. A companys Strengths and Weaknesses are generally internal, while the Opportunities and Threats are external factors. To spare most of the readers of this analysis, this SWOT is going to be a little less in depth than a typical SWOT analysis. However, it will be detailed enough to outline and discuss what I feel are the key items in each area of the analysis. STRENGTHS The Google Brand-Google is one of the most well known and respected technology companies on the planet. The fact that they are behind the Android platform gives it credibility and viability in the eyes of potential partners, vendors, and developers. Device Selection-Unlike the Apple iPhone where you dont have any options of hardware suppliers other than Apple itself, the Android OS is open-source and any hardware manufacturer who chooses to do so can use it on their handset. This gives consumers a great deal of selection from which to choose from while also decreasing the lead time to the use of the latest hardware and technological advances in mobile electronics. Competitive Pricing-The Android OS is very cost effective to develop for since it is open source and the licensing arrangements are very vendor friendly. Thus, handsets utilizing the Android OS tend to be prices very aggressively. Google application and services integration-The fact that the Android platform integrates so many of the Google services and applications into its base only strengthens its core capabilities and usefulness. Google items such as GMAIL, Calendar, Reader, Listen, and of course GPS and Maps to name a few integrate seamlessly with the Android OS and make it very simple for users to synchronize their data across platforms from the desktop to the cloud and mobile platforms. Open Source-The Android OS is built from a Linux base using the JAVA Programming language. You can go directly to the http://source.android.com website and find the information and source code you need to build a compatible device for Android. Additionally, Android is a core part of the OHA (Open Handset Alliance) which is a group of companies working together to develop Android as an open and free mobile platform. Google Assets-The Android team(s) has all the intellectual, economic, and influential resources of Google at its disposal to make it a dominant player in the mobile marketplace. WEAKNESSES Multimedia Support-Unlike the Apple iPhone which has the enormously popular iTunes application and marketplace, Android does not have a central or cohesive source of multimedia material nor a centralized player. Although there have been some improvements in applications on the Android platform in this area, at this time there is no â€Å"the† place to go that comes even slightly close to what Apple can offer on this front. However, there are numerous rumors to what exactly Google has in store for a music service of its own to be released sometime in late 2010. Whatever it is, it needs to be extremely well executed to come close to what iTunes offers Apple iPhone users. The one large asset Google has going for it is YouTube, and their recent announcement ofWebM(VP8) could become a lever for multimedia influence in video delivery for Google and the Android OS. Reliance on hardware makers to upgrade-Apple controls the when and how iPhone users will get not only new hardware, but upgrades to the OS and core functionality. With Android, even when Google releases a new version of its OS, it has to wait for the manufacturers to thoroughly test and modify code to make sure it works properly on their specific hardware configuration. Google is addressing this issue as it has announced that it plans to implement more of the core features of its services into the Android OS itself instead of as applications, and to slow down the upgrade releases as the OS matures in the marketplace. Less Mature-Android is not as mature or as polished as the iPhone at this point. It improves with every release, but it hasnt reached the same level of overall user friendliness in its interface that Apple has achieved. Lack of Enterprise Support-Blackberry and even Microsoft still get most of the support when it comes to Enterprise usage. Although both Apple and Google have made some inroads in this marketplace, Android has a very small market share here. It needs to continue to develop Google Apps and its integration abilities with Microsoft Exchange. OPPORTUNITIES The Android OS has a â€Å"HUGE† opportunity to get into the Tablet and e-book reader platform market right now. It cannot afford to sit back and watch Apple dominate the tablet market and eat up the market share as it had done when it released the iPhone. To date, that is exactly what is happening as no major hardware ‘mover and shaker has released an Android based tablet which is a fantastic opportunity if it is executed properly. I want one NOW! There have been several minor releases of Android tablets over the last few months, but none of them are what I would consider a significant product. Either Google itself or someone such as HP, Dell, ASUS, or ACER need to release a killer Android tablet in order for it to gather any traction. These waters only became murkier when HP acquired PALM. Developing Countries-Google has a huge opportunity to develop inexpensive devices using the Android platform in developing countries. The licensing is extremely developer friendly and the upfront cost investments are significantly less than other platforms. The integration with so many of Googles other free services is a natural fit in this marketplace. Developer Friendly-Unlike the recent activities of Apple which has alienated and ticked off much of the developer community, developing for Android is very open and developer friendly. Google needs to take this opportunity to help developers continue to monetize their efforts through improved advertising revenue models and app sales. Growth of smartphone market-The smartphone market is still very immature and there is still a huge amount of growth to take place over the next several years to decade. Google needs to continue to work hard to position itself with its cloud computing applications and services in support of the Android OS. The marriage of these two areas is key to the maintained growth rate and increased market share potential of the Android platform. Embedded electronic devices-The Android OS has huge potential to be a major player in the embedded electronic market as a dominate embedded operating system. With so many devices becoming embedded with smart technologies and connectivity to the cloud, the Android OS is primed to be a major winner there. THREATS iPhone unleashed-If the iPhone is unleashed from the beaten down ATT network and appears on other networks such as Sprint and in particular, Verizon, it could be a real threat to the sustained rate of future market share growth for the Android OS. A significant amount of potential smartphone customers said they would buy an iPhone if it werent on the ATT network. (I was once in this camp, until I discovered the world of Android.) Apple dominance-Apples market share gives it a great influence over developers and old media companies who are dying for a revenue model that will work for them. The ever growing walled garden that Apple is building is a false panacea that the old media companies are holding onto with both hands-the ability to charge users for access to premium content. Apples recent changes in policy and functional restrictions make it the ideal platform to launch such a strategy and recruit the power brokers from this old model. Additionally, the â€Å"theres an app for that† and Im willing to pay for it behavior of Apple iPhone users is of great appeal to developers who see the dollar signs in this market. (Ive yet to pay for an application on Android) This gives Apple influence over developers and makes their huge market share very difficult to walk away from, even when they adopt very unfriendly developer policies. Increased Competition-Obviously, companies like RIM and Microsoft are going to fight for their share of the market and arent going to just give up. In particular, the Blackberry platform which still has huge support in the enterprise market. Platform Fragmentation-This is a huge threat to the Android platform. Although I listed the numerous devices as a strength above, the risk of fragmentation is a real and significant one. This is why Google has recently put a lot of effort into developing ways to minimize this problem. Google does not want numerous custom version of Android to emerge or fork off from their core platform, which is something you see in the Linux distribution network. Google is developing a set of baseline standards for compatibility for its platform. Since Google controls the Android Market, it can maintain significant influence over device vendors to meet the compatibility requirements. If you do a little research on this topic, you will see that Googles standards are fairly rigid, maybe more so than one would expect. Google also plans to adopt aonce-per-yearrelease schedule as well. None the less, managing this risk is a major and real threat to the Android platform. So there you have it, my basic SWOT analysis for Google Android. One underlying issue I feel is worth noting is that Google does not have to dominate, and as much as so many of us would love to see it, it does not have to â€Å"beat† Apple in market share or any other core metric. The only thing Google needs to do is to make sure there is an open platform large enough in the mobile market for its advertising business. Lets face it; Google is not about selling Android devices. Google is about search and advertising, and Apples closed system was a threat to that model which has become even more self-evident over the last six to nine months of Apple policies and maneuverings. Apple recently announced their own Ad network for the iPhone and iPad which could be viewed as a shot across the bow of Google which puts even more necessity on the Android platforms success. The clear advantage that Google has going for itself right now is that Apple (Steve Jobs) is either being indignant o ver what cloud computing actually does and means, or he truly doesnt understand or hasnt figured out how its suppose to work. Considering how intelligent Steve Jobs is, I find it highly unlikely that the second option is the reason, and that his stubbornness and willingness to maintain personal grudges as the likely culprit. 2.3 Overview of the Closed Source Operating Systems (Apple IOS). If theres one company that is the envy of the high-tech community these days, its Apple. Steve Jobs is hailed as a genius CEO and lauded for a string of hit products. Apples market capitalization is over $200 BILLION dollars currently, easily ranking it in the top 10 companies in the world by market cap, and just shy of Microsoft for biggest technology company. Everyone wants to understand the secrets of Apples success and hopefully emulate them. The reasons given by people for Apples success are many. The following are a few of the arguments made: Vertical integration- Apple owns most of, if not the entire, technology stack for its key products, and thus gives it advantages over other less vertically integrated products. NOTE: â€Å"Vertical integration† used to be called â€Å"being proprietary† and was given as the reason for Apples relative lack of success against Microsoft in the OS/PC battles of the 80s and 9os. But phenomenal success has a way of changing peoples minds. Making markets vs. addressing markets- Some claim that Apple doesnt ask people what they need but gives them products they decide theywant. Does anyone NEED an iPhone or iPad? Not really, but a lot of people seem to want them. The Cool Factor- Lets face it, Apple does make â€Å"cool† products. Attention to design and detail-fit and finish as they say-really distinguishes Apples products from competitors. Entering markets after theyve developed— Contrary to #2 above, some people claim that Apple doesnt make markets but enters existing markets once theyre growing and takes advantage of latent demand. The iPod was not the first digital music player and the iPhone was not the first smart phone, and the iPad is not the first portable computing device. In the case of the iPad, products like the Kindle and Netbooks actually paved the way for the market to accept small computing devices, and Apples iPad is riding that wave. Differentiated business models- whether it was iPod+iTunes or the iPhone+App Store, Apple innovates not just on technology, but on the business model. This makes it difficult for competitors to play catch up, let alone overtake Apple once it establishes itself in a dominant position. People care about the experience not technology— Apple has always been about the user experience, but for a long time, the majority of the market didnt care about that. The majority of desktop computer users cared about â€Å"techs and specs†. Now the tables have turned, and the majority dont care about the specs, they care about the experience. The iPod, with its â€Å"1000 songs in your pocket† motto and iTunes which radically simplified purchasing music latched onto the experience wave, and Apple has been riding it ever since. Simple product offerings- Apple has a very clear and simple set of products. Its easy to understand the differences between their products, product families and the various configurations. This makes it easy to buy an Apple product if you want to. A lot of companies complicate things unnecessarily. How many iPhone models are there? How many Blackberry models are there? How many Nokia smart phone models are there? See the difference between Apple, RIM and Nokia? The same is true for the iMAc, the iPod and the iPad. Granted, there are actually a number of iPod models (Nano, Shuffle, Touch etc.) but they are very distinct amongst themselves. This cant be said for digital music players from other companies. 2.3.1 Apple Competitive Analysis: Future Goals Apple has been and continues to focus on what its competitors are doing in order to keep a competitive strategy. Steve Jobs wanted to create a brand loyal name and to also produce a personalized computer with many features that would allow your life to be easier. Apple needed to keep up with rapid price cuts of its competitors personalized computers that were based on other operating systems. They wanted to focus on the rapid technological advances in both hardware and software that would boost their computers performance and provide its own operating systems. By doing so, the iMac-personalized computer was introduced in 1997 and they were able to create the brand loyalty they were looking for. They want to continue to build the brand loyal name and keep giving the consumer what they want to make their lives easier. Current Strategy Steve Jobs has recognized that many of its competitors have been providing computers that rely heavily on other operating systems to run their computers. For example, Dell computers rely on windows XP, and many of their software products rely on other partys. What Steve Jobs has managed to do is to incorporate its own operating systems, hardware, and software programs for its entire product line. The software that they have created would allow the user to edit videos, download and play music, edit pictures, etc. with all of their own products and applications. While other competition relied on outside companies introducing their own digital and distribution music product services, subscription services, and free peer-to-peer music services; Apple has created a way to counter the constant changing competitive market. They have done so by effectively integrating all three services that its competitors have to choose from by creating the iPod for hardware, iTunes for software, and iTune s Music Store for the third party distribution services. Apple has been able to eliminate its reliance on outside companies and to keep on creating specialized programs for consumers. Another factor that has helped keep Apples future thriving is by introducing the Apple Store. Customers are now able to take their products into the store and have an apple specialist examine/work on the products that they are heavily invested in. Most competitors would have the consumer take computer/product to a tech department of a store or would have to send to a third party. Assumptions and Capabilities Apple has done a tremendous job of knowing and anticipating what his competitors are doing. Apple was able to develop its iPhone and music player technology into a mobile phone. The Rokr was the mobile phone device that was developed by Motorola. The device contained quality sound and included an advanced camera system. A version of Apples iTunes music store has been developed for the iPhone so users can manage music and can download other applications that Apple has to offer. An Apple consumer can browse the web faster than its competitors. These capabilities make the iPhone ideal for both business and travel. By knowing the competitors moves and capabilities Apple was able to perfect a phone that could offer more programs and applications than any other phone. The company was then able to then focus on the strengths and weakness of its competition and compare it to the products they provide. The company believes in the highest quality of products. Thes e products will continue to provide what every customer wants and needs, a computer company that continuously makes life easi Open Source vs Closed Source Systems Open Source vs Closed Source Systems INTRODUCTION For many years, proprietary software has been the dominating business approach used by the commercial software firms. Industry giants like Microsoft proved this strategy to be successful, building their multibillion dollar empires based on the proprietary software platform. Over the past decade, a new business approach called open source model which involves contributors from around the globe to create, share and distribute software code for free had come into practice (Pal, N Madanmohan, TR., 2002). Although the roots to this practice of sharing code evolved since early 60s, the widespread usage of internet and the technology developments in past two decades opened new opportunities for open source projects (CNET news, 1998). A number of Open Source Software (OSS) products such as Apache web server, BIND and SendMail have dominated their product categories ever since then (Pal, N Madanmohan, TR., 2002). In the past decade, several researchers (Wheeler, DA., 2007; Mockus, et al., 2000) have taken interest in studying how open source can be applied to modern business strategies. However, a concern exists that in this area of study that there is no substantial evidence that the practices followed are effective in the business environment (Bitzer Schrà ¶der, 2004). For economists like Lerner Tirole (2000), the altruism shown by commercial companies and programmers involved in an open source software project is surprising. They stated altruism hasnt played a major role in any other industry than software. Several others like Freeman Rogers (2008) and Goetz (2003) contradict this statement by illustrating altruism exist in any industry provided there is proper exposure of the problem towards the contributing community. But most of the researches surrounding open source model considered software industry as the base for their studies. 1.0 SCOPE OF THE PROJECT 1.1 Objective This project work focuses on the study of the Open Source ecosystem (Android) how it differs from Closed source sustems such as those surrounding the iPhone. This project includes the study of the Android Market, (online mobile application store for Android users) application developers, and which factors developers consider for selecting a platform for application development. To understand business strategy development trends across Android and iPhone platforms, we compared the Android market with the iPhone App Store, the leading application store in current mobile market. Apple launched an online application marketplace called the â€Å"iPhone App Store† before launching iPhone 3G. Currently, this store has more than 195,000 applications. To match or surpass the success of iPhone App Store, Apple rivals such as Google and Blackberry introduced their own application downloading stores called â€Å"Android Market† and â€Å"Blackberry App World† respectively. T he Android Market is similar to the iPhone App Store or to any other application store; it boasts a catalog of applications,  services and tools available for the user to purchase download and use. Today, the Android Market also has around 49,000 applications. Thus, the comparison between iPhone and Android application stores will help explain the new challenges faced by these two application stores, and also the demand for these stores in the near future. This study will help understand why Android choose Open Source System and why Apple doesnt, what determines their success, which large companies are directly involved in developing applications for Android, and which factors they consider for developing an application. 1.2 Experimental Procedures This project is based on a semi-automatically collected application database and   surveys to obtain necessary information for proving the hypothesis. (A) Website Data Firstly, application data were collected semi-automatically from the Android Market and iPhone App Store (iTunes store) and other mobile applications related websites, for e.g., Androlib.com, iPhoneapplicationlist.com. This gathered application database includes a list of the application categories on both platforms, number of applications in each category, and application information for the selected categories. (B) Interview Data Next, we interviewed mobile application developers to understand and know their views about Android/iPhone platforms and the ecosystem. To get in touch with mobile application developers, we attended the mobile conferences where they gather to share their views. (C) Survey Data Lastly, all the relevant facts about application developers from the interview data helped us prepare a survey. This web-based survey was prepared and conducted using Survey Monkey. 1.3 Resources Utilized The main resources used during this project were our industrial advisor, our academic reader, Android and iPhone application database, interviews and surveys from mobile application developers. 2.0 LITERATURE REVIEW 2.1 Introduction of Literature Review In order to achieve success in project implementation, the first step is to research and find information already available. During research, we found many articles related to our topic. This paper is based on the content from these articles. We have divided this section in four main areas: Overview of the Open Source Operating Systems (Android). Overview of the Closed Source Operating Systems (Apple IOS). Fundamentals behind the Open Source Platform. Introduction to the Smartphone. 2.2 Overview of the Open Source Operating Systems (Android). Google has achieved something remarkable with its open-source Android operating system. SinceApples iPhonerevolutionised thesmartphonein June 2007, bringing touchscreens and a beautiful user experience to the masses, its been without a rival. Sure, theres a small legion of BlackBerry fans, and a few Nokia die-hards, but the critical consensus up until about a year ago was that the iPhones achievements were peerless. EnterAndroid. The free, open-source mobile operating system was introduced to consumers with theHTC Dream(also known as theT-Mobile G1) in late 2008, but didnt start gaining steam until the release of theHTC Heroin July 2009. The Hero, armed with a custom user interface called Sense that HTC built in-house, gained rave reviews for its high-end specs and faultless user experience, and appeared on many critics lists of the best gadgets of 2009. The whispers began: Had Google managed to create a platform that genuinely rivalled the iPhone for the best smartphone experience around? This success is starting to show in the numbers. In February 2010, Google announced that more than 60,000 phones with Android on were shipping each day. The Android App Market is also booming, housing more than 30,000 downloadable applications in March 2010, although thats still comparably small when set beside the 185,000 or so Apple has in its App Store. But where once companies had to have an iPhone app, its now understood that they need to offer both an iPhone and an Android variant. Manufacturers havent let the opportunity pass them by, either. At the time of writing, there are around 35 mobile phones, five tablet PCs, three e-book readers and a netbook available that come with Android installed a total of about 43 devices. But thats nothing compared to the amount of gadgets that are purportedly in the works. If you tot up the rumours, statements of intent, leaked documents and roadmapped products from manufacturers, you can add at least another 15 smartphones, 19 tablet PCs, two e-book readers and three more netbooks to the pile. When you combine the totals, you arrive at a figure of at least 82 Android devices either released or in development. The platform has received four major updates since the HTC Dream launched with Android 1.0. Version 1.5 brought camcorder functionality and the ability to use homescreen widgets. Version 1.6 added voice search and a better Android App Market. Then version 2.0 revamped the user interface, added new, larger screen sizes, as well as navigation support in Google Maps. The latest update is version 2.1, which debuted on theNexus One a handset built by HTC but to specifications dictated by Google itself. Android 2.1 brings additional homescreens, animated wallpapers and the ability to use voice recognition to type in all text fields very useful if youre in a situation where you cant use an on-screen keypad, such as when driving. Other devices are starting to appear with version 2.1 as well the Motorola Droid, known as theMilestone in Europe, recently received an update to 2.1, and HTCs forthcoming Legend and Desire handsets come with it installed. Oldhardware=nonewtricks However, the new features available in 2.1 come with increased demand on the relatively weak processors found in most smartphones, particularly in the earlier Android devices. As a result, some handsets cant run later versions of Android at satisfactory speed. Even in those that can, manufacturers have been exceptionally slow at rolling out updates to their device owners, with HTC still not having delivered any update above 1.5 for its Hero at the time of writing. Its difficult to fault Google for wanting to update its core platform as fast as it can. The problem is that its going so fast that manufacturers cant roll out updates to their own software at a speed to match. The upshot for users is that early Android adopters are stuck on two-year contracts looking mournfully at all the fun that new device owners can get, with no knowledge as to whether theyll eventually have access to the new features themselves. This isnt anything new in most cases other manufacturers dont grant older gadget owners access to new features but its tough on Android users in particular because the pace of the updates is so fast. A phone can be out-of-date within months of its release, and in some cases handsets are still arriving with Android version 1.6 installed. App developers suffer, too. Many of Googles home-grown applications Maps, Earth, Goggles and Gesture Search were initially only released for the 2.0 and 2.1 platforms. Some have since gained backwards compatibility to 1.6, but HTC Hero owners, running 1.5, still cant use them. App developers have a tough choice to make: support as wide a range of phones as possible, or offer an app with superior features, but only to those running the latest Android builds. Situationnormal: Allforkedup So what can Google do about the problem? The company is stuck with four slightly different variants of its platform in the wild, and its got a splintered marketplace where one Android user cant necessarily access the same apps that another can, and its confusing and frustrating for end users. The obvious way ahead is to try and force manufacturers to update the software on their devices. Any device running 1.5 should be able to cope with 1.6, and a 2.0 device will manage 2.1. While that still leaves the problem of devices that cant quite cope with the most recent updates, Google should be able to merge its four shards into two a set of 1.6 devices and a set of 2.1 devices simplifying the situation somewhat. However, that relies on the goodwill and resources of a diverse set of companies, and some of those will only have dipped a toe into the waters of Android, meaning that they might be less keen to start devoting significant staff time to mucking around with operating system updates. So Googles got another trick up its sleeve. Recent rumours suggest that the company, in the upcoming version 2.2 update, is planning to de-couple the various applications that run on the device from the operating system itself. The browser, email apps, contacts, input methods and various other components will be downloadable and, crucially, updatable through the Android market rather than needing to wait for a full OS update to be upgraded. When Google wants to update the Gmail app, it can just push a market update, rather than forcing customers to wait for HTC, Dell, Samsung or other manufacturers to approve it. If Google fails to unify the Android platform, a future looms where Android is stuck in a series of ghettoes, with no guarantee that one Android user will be able to run the same apps as another unless they buy a new device every six months. Thats good news for manufacturers, but very bad news for Google and for consumers. If Google manages the transition successfully however, then a unified (or at least consolidated) platform could be easily updated by both Google and phone-makers, depending on whether the update is a critical security issue or a new feature in an application. Time is pressing. The fate of Android rests on what Google does over the summer of 2010. Will the platform fall by the wayside, or will it instead grow to be the Windows of smartphones, carefully balancing openness to app developers with a superior user experience and mass-market appeal? On past form, it seems foolish to bet against Google. Let us also look at the SORT analysis for android: Being a self declared Google and Android fanboy, Im constantly reading and studying about cloud computing and the mobile marketplace whenever I have the opportunity. Ive even begun the very first steps of beginning to learn programming Java for the Android platform, although this is a ‘free time endeavor which is going to take quite some time for me to get even the basic level of proficiency achieved. 2.2.1 SWOT Analyses for GOOGLE ANDROID But one area where I feel comfortable in discussion and analysis is in the business realm, which is why I decided to do a basic SWOT analysis for Google Android. It is a tool used in strategic planning to evaluateStrengths,Weaknesses,Opportunities, andThreats involved in a project or business. A companys Strengths and Weaknesses are generally internal, while the Opportunities and Threats are external factors. To spare most of the readers of this analysis, this SWOT is going to be a little less in depth than a typical SWOT analysis. However, it will be detailed enough to outline and discuss what I feel are the key items in each area of the analysis. STRENGTHS The Google Brand-Google is one of the most well known and respected technology companies on the planet. The fact that they are behind the Android platform gives it credibility and viability in the eyes of potential partners, vendors, and developers. Device Selection-Unlike the Apple iPhone where you dont have any options of hardware suppliers other than Apple itself, the Android OS is open-source and any hardware manufacturer who chooses to do so can use it on their handset. This gives consumers a great deal of selection from which to choose from while also decreasing the lead time to the use of the latest hardware and technological advances in mobile electronics. Competitive Pricing-The Android OS is very cost effective to develop for since it is open source and the licensing arrangements are very vendor friendly. Thus, handsets utilizing the Android OS tend to be prices very aggressively. Google application and services integration-The fact that the Android platform integrates so many of the Google services and applications into its base only strengthens its core capabilities and usefulness. Google items such as GMAIL, Calendar, Reader, Listen, and of course GPS and Maps to name a few integrate seamlessly with the Android OS and make it very simple for users to synchronize their data across platforms from the desktop to the cloud and mobile platforms. Open Source-The Android OS is built from a Linux base using the JAVA Programming language. You can go directly to the http://source.android.com website and find the information and source code you need to build a compatible device for Android. Additionally, Android is a core part of the OHA (Open Handset Alliance) which is a group of companies working together to develop Android as an open and free mobile platform. Google Assets-The Android team(s) has all the intellectual, economic, and influential resources of Google at its disposal to make it a dominant player in the mobile marketplace. WEAKNESSES Multimedia Support-Unlike the Apple iPhone which has the enormously popular iTunes application and marketplace, Android does not have a central or cohesive source of multimedia material nor a centralized player. Although there have been some improvements in applications on the Android platform in this area, at this time there is no â€Å"the† place to go that comes even slightly close to what Apple can offer on this front. However, there are numerous rumors to what exactly Google has in store for a music service of its own to be released sometime in late 2010. Whatever it is, it needs to be extremely well executed to come close to what iTunes offers Apple iPhone users. The one large asset Google has going for it is YouTube, and their recent announcement ofWebM(VP8) could become a lever for multimedia influence in video delivery for Google and the Android OS. Reliance on hardware makers to upgrade-Apple controls the when and how iPhone users will get not only new hardware, but upgrades to the OS and core functionality. With Android, even when Google releases a new version of its OS, it has to wait for the manufacturers to thoroughly test and modify code to make sure it works properly on their specific hardware configuration. Google is addressing this issue as it has announced that it plans to implement more of the core features of its services into the Android OS itself instead of as applications, and to slow down the upgrade releases as the OS matures in the marketplace. Less Mature-Android is not as mature or as polished as the iPhone at this point. It improves with every release, but it hasnt reached the same level of overall user friendliness in its interface that Apple has achieved. Lack of Enterprise Support-Blackberry and even Microsoft still get most of the support when it comes to Enterprise usage. Although both Apple and Google have made some inroads in this marketplace, Android has a very small market share here. It needs to continue to develop Google Apps and its integration abilities with Microsoft Exchange. OPPORTUNITIES The Android OS has a â€Å"HUGE† opportunity to get into the Tablet and e-book reader platform market right now. It cannot afford to sit back and watch Apple dominate the tablet market and eat up the market share as it had done when it released the iPhone. To date, that is exactly what is happening as no major hardware ‘mover and shaker has released an Android based tablet which is a fantastic opportunity if it is executed properly. I want one NOW! There have been several minor releases of Android tablets over the last few months, but none of them are what I would consider a significant product. Either Google itself or someone such as HP, Dell, ASUS, or ACER need to release a killer Android tablet in order for it to gather any traction. These waters only became murkier when HP acquired PALM. Developing Countries-Google has a huge opportunity to develop inexpensive devices using the Android platform in developing countries. The licensing is extremely developer friendly and the upfront cost investments are significantly less than other platforms. The integration with so many of Googles other free services is a natural fit in this marketplace. Developer Friendly-Unlike the recent activities of Apple which has alienated and ticked off much of the developer community, developing for Android is very open and developer friendly. Google needs to take this opportunity to help developers continue to monetize their efforts through improved advertising revenue models and app sales. Growth of smartphone market-The smartphone market is still very immature and there is still a huge amount of growth to take place over the next several years to decade. Google needs to continue to work hard to position itself with its cloud computing applications and services in support of the Android OS. The marriage of these two areas is key to the maintained growth rate and increased market share potential of the Android platform. Embedded electronic devices-The Android OS has huge potential to be a major player in the embedded electronic market as a dominate embedded operating system. With so many devices becoming embedded with smart technologies and connectivity to the cloud, the Android OS is primed to be a major winner there. THREATS iPhone unleashed-If the iPhone is unleashed from the beaten down ATT network and appears on other networks such as Sprint and in particular, Verizon, it could be a real threat to the sustained rate of future market share growth for the Android OS. A significant amount of potential smartphone customers said they would buy an iPhone if it werent on the ATT network. (I was once in this camp, until I discovered the world of Android.) Apple dominance-Apples market share gives it a great influence over developers and old media companies who are dying for a revenue model that will work for them. The ever growing walled garden that Apple is building is a false panacea that the old media companies are holding onto with both hands-the ability to charge users for access to premium content. Apples recent changes in policy and functional restrictions make it the ideal platform to launch such a strategy and recruit the power brokers from this old model. Additionally, the â€Å"theres an app for that† and Im willing to pay for it behavior of Apple iPhone users is of great appeal to developers who see the dollar signs in this market. (Ive yet to pay for an application on Android) This gives Apple influence over developers and makes their huge market share very difficult to walk away from, even when they adopt very unfriendly developer policies. Increased Competition-Obviously, companies like RIM and Microsoft are going to fight for their share of the market and arent going to just give up. In particular, the Blackberry platform which still has huge support in the enterprise market. Platform Fragmentation-This is a huge threat to the Android platform. Although I listed the numerous devices as a strength above, the risk of fragmentation is a real and significant one. This is why Google has recently put a lot of effort into developing ways to minimize this problem. Google does not want numerous custom version of Android to emerge or fork off from their core platform, which is something you see in the Linux distribution network. Google is developing a set of baseline standards for compatibility for its platform. Since Google controls the Android Market, it can maintain significant influence over device vendors to meet the compatibility requirements. If you do a little research on this topic, you will see that Googles standards are fairly rigid, maybe more so than one would expect. Google also plans to adopt aonce-per-yearrelease schedule as well. None the less, managing this risk is a major and real threat to the Android platform. So there you have it, my basic SWOT analysis for Google Android. One underlying issue I feel is worth noting is that Google does not have to dominate, and as much as so many of us would love to see it, it does not have to â€Å"beat† Apple in market share or any other core metric. The only thing Google needs to do is to make sure there is an open platform large enough in the mobile market for its advertising business. Lets face it; Google is not about selling Android devices. Google is about search and advertising, and Apples closed system was a threat to that model which has become even more self-evident over the last six to nine months of Apple policies and maneuverings. Apple recently announced their own Ad network for the iPhone and iPad which could be viewed as a shot across the bow of Google which puts even more necessity on the Android platforms success. The clear advantage that Google has going for itself right now is that Apple (Steve Jobs) is either being indignant o ver what cloud computing actually does and means, or he truly doesnt understand or hasnt figured out how its suppose to work. Considering how intelligent Steve Jobs is, I find it highly unlikely that the second option is the reason, and that his stubbornness and willingness to maintain personal grudges as the likely culprit. 2.3 Overview of the Closed Source Operating Systems (Apple IOS). If theres one company that is the envy of the high-tech community these days, its Apple. Steve Jobs is hailed as a genius CEO and lauded for a string of hit products. Apples market capitalization is over $200 BILLION dollars currently, easily ranking it in the top 10 companies in the world by market cap, and just shy of Microsoft for biggest technology company. Everyone wants to understand the secrets of Apples success and hopefully emulate them. The reasons given by people for Apples success are many. The following are a few of the arguments made: Vertical integration- Apple owns most of, if not the entire, technology stack for its key products, and thus gives it advantages over other less vertically integrated products.

The iPod, with its â€Å"1000 songs in your pocket† motto and iTunes which radically simplified purchasing music latched onto the experience wave, and Apple has been riding it ever since. Simple product offerings- Apple has a very clear and simple set of products. Its easy to understand the differences between their products, product families and the various configurations. This makes it easy to buy an Apple product if you want to. A lot of companies complicate things unnecessarily. How many iPhone models are there? How many Blackberry models are there? How many Nokia smart phone models are there? See the difference between Apple, RIM and Nokia? The same is true for the iMAc, the iPod and the iPad. Granted, there are actually a number of iPod models (Nano, Shuffle, Touch etc.) but they are very distinct amongst themselves. This cant be said for digital music players from other companies. 2.3.1 Apple Competitive Analysis: Future Goals Apple has been and continues to focus on what its competitors are doing in order to keep a competitive strategy. Steve Jobs wanted to create a brand loyal name and to also produce a personalized computer with many features that would allow your life to be easier.

By doing so, the iMac-personalized computer was introduced in 1997 and they were able to create the brand loyalty they were looking for. They want to continue to build the brand loyal name and keep giving the consumer what they want to make their lives easier. Current Strategy Steve Jobs has recognized that many of its competitors have been providing computers that rely heavily on other operating systems to run their computers. For example, Dell computers rely on windows XP, and many of their software products rely on other partys. What Steve Jobs has managed to do is to incorporate its own operating systems, hardware, and software programs for its entire product line. The software that they have created would allow the user to edit videos, download and play music, edit pictures, etc. with all of their own products and applications. While other competition relied on outside companies introducing their own digital and distribution music product services, subscription services, and free peer-to-peer music services; Apple has created a way to counter the constant changing competitive market. They have done so by effectively integrating all three services that its competitors have to choose from by creating the iPod for hardware, iTunes for software, and iTune s Music Store for the third party distribution services.

Customers are now able to take their products into the store and have an apple specialist examine/work on the products that they are heavily invested in. Most competitors would have the consumer take computer/product to a tech department of a store or would have to send to a third party. Assumptions and Capabilities Apple has done a tremendous job of knowing and anticipating what his competitors are doing. Apple was able to develop its iPhone and music player technology into a mobile phone. The Rokr was the mobile phone device that was developed by Motorola.

However at a given temperature, the average kinetic energy of the gas molecules remains constant. If at a given temperature, n1 molecules have speed v1, n2 molecules have speed v2, n3 molecules have speed v3, and so on. Then, the total kinetic energy (EK) of the gas at this temperature is given by where m is the mass of the molecule. The corresponding average kinetic energy ( If the following term Then the average kinetic energy is given by where c is given by 4 ) of the gas will beThis ‘c’ is known as root-mean-square speed. As the name implies, to calculate c, first take the squares of the individual speeds , then their mean and finally the square root of the mean. It can be shown that c is related to temperature by The average kinetic energy depends only on absolute temperature and is related to absolute temperature by the expression where k = Boltzmann constant = 1. 38 x 10-23 J K-1 In the case of gases, one also talks of two other speeds, namely, average speed and most-probable speed. The average speed ( ) at a given temperature is the arithmetic mean of the speeds of different molecules of the gas. . e, where n1 molecules have speed v1, n2 molecules have speed v2, n3 molecules have speed v3, and so on. The relationship between average speed and temperature T is given by The most probable speed ( ) of a gas at a given temperature is the speed possessed by the maximum number of molecules at that temperature. Unlike average speed and root mean square speed, the most probable speed cannot be expressed in terms of the individual molecular speeds. The most probable speed ( ) is related t o absolute temperature (T) by the expression 5 Relationship between different types of molecular speedsThe three types of molecular speeds, namely, most probable speed ( ), average speed ( ) and root mean square speed (c) of a gas at a given temperature are related to each other as follows: For a particular gas, at a particular temperature, It follows from the above relationships that Example: Calculate the root mean square, average and most probable speeds of oxygen molecules at 27 oC. Solution: Given data: Molar mass of oxygen, M = 32 g mol-1 = 0. 032 kg mol-1 Temperature, t = 27 oC T = (27 + 273) K = 300 K 6 Expressions to be used: Root mean square speed, Average speed, Most probable speed, Actual calculationsRoot mean square speed, Average speed, Most probable speed, 5. 7. 2 MAXWELL-BOLTZMANN DISTRIBUTION OF MOLECULAR SPEEDS The speeds of the individual molecules of a gas do not remain constant. They keep on changing due to inter molecular collisions and due to collisions with t he walls of the container. However, at a given temperature, the distribution of molecular speeds remains constant. This distribution of molecular speeds is given by Maxwell-Boltzmann distribution law. 7 For a given gas, at a given temperature, the distribution curve of molecular speeds is shown in Figure 5. 7. 1 Figure 5. 7. 1.Maxwell Boltzmann distribution curve You can see from the distribution curve that it is the plot of molecular speed vs the fraction of molecules. The important features of this distribution curve are: (i) The fraction of molecules having too low or too high speeds is very small. (ii) There is a certain speed for which the fraction of molecules is maximum. This speed is known as most probable speed. (iii) The most probable speed of a gas, is the speed possessed by the maximum number of molecules of the gas at a given temperature and it corresponds to the peak of the curve. Since the most probable speed ( xpression ) is related to absolute temperature T by the I t means that at the same temperature, lighter gases shall move faster than heavier gases as is evident from the distribution curves of chlorine and nitrogen gases in Figure 5. 7. 2. 8 Figure 5. 7. 2. Maxwell Boltzmann distribution curves for chlorine and nitrogen gases at 300K Effect of temperature In Figure 5. 7. 3. are given the Maxwell Boltzmann distribution curves of a gas at three different temperatures T1, T2 and T3 such that T1>T2>T3. Figure 5. 7. 3. Maxwell Boltzmann distribution curves for a gas at three different temperatures 9It can be seen from these distribution curves that as the temperature increases 1. The entire curve shifts towards right. 2. The most probable speed increases. 3. The fraction of molecules having most probable speed decreases. 4. The curve becomes broader in the middle range indicating that more molecules have speeds near to the most probable speed. 5. The fraction of molecules having higher speeds increases. 6. The fraction of molecules having lower speed decreases. It may be noted that the total area under each of the curves remains the same as the sum of fractions of molecules remains unaltered on changing the temperature. 0 EXERCISE 1.

This law is always obeyed whether a given process occurs on its own or is made to occur with the help of an external agency.In any case the first law is valid in both the forward and reverse direction of the process. You have also learnt about the concept of entropy which is a measure of the randomness or the disorder in a system. This concept helps in explaining the spontaneity of the irreversible processes. For an irreversible process, the entropy of the system and surroundings taken together i. e. of the universe increases, while for a process at equilibrium it remains constant. This conclusion is of great importance as it helps us to predict whether a given process can take place spontaneously or not.Since a ll processes in nature occur spontaneously i. e. irreversibly, it follows that the entropy of the universe is increasing continuously. This important statement i. e. â€Å"in any spontaneous process, the entropy of the universe (system and surroundings) always increases† is also known as the second law of thermodynamics. ?SUniverse = ? Ssystem + ? Ssurroundings Specifically it means that If ? SUniverse > 0, the reaction is spontaneous If ? SUniverse < 0, the reaction is non-spontaneous If ? SUniverse = 0, the reaction is at equilibriumSince chemists are generally more interested in the system (reaction mixture) than the surroundings, it is therefore more convenient to restate the second law in terms of the thermodynamic properties of the system, without regard to the surroundings. As already described in the previous section, this is possible through the Gibbs free energy G which for a system is defined as G = H – TS. In terms of this thermodynamic property, the second law of thermodynamics can be restated as in any spontaneous process at 13 constant temperature and pressure, the free energy of the system (? Gsystem) always decreases.According to this definition If ? Gsystem < 0, the reaction is spontaneous If ? Gsystem > 0, the reaction is non-spontaneous If ?Gsystem = 0, the reaction is at equilibrium 6. 8. THIRD LAW OF THERMODYNAMICS The third law of thermodynamics is concerned with determination of entropy. It states that a substance which is perfectly crystalline at absolute zero of temperature has an entropy of zero. In a perfect crystal at absolute zero of temperature, each constituent of the crystal (atom, molecule or ion) is at the proper crystal lattice site and it therefore has the lowest energy.This means that this particular state is of perfect order, i. e, has zero disorder and hence zero entropy. Using zero value of entropy at absolute zero for a perfectly crystalline substance as the reference point (initial state), on e can calculate absolute value of entropy of the substance in any state (solid, liquid or gas) at any temperature by calculating ? S for the process/es in going from the initial state to the state of the substance for which entropy is to be calculated. However there are certain substances which possess certain entropy even at absolute zero.This entropy is known as residual entropy. The origin of residual entropy can be explained on the basis of the disorder which remains at absolute zero in certain crystals composed of AB types of molecules where A and B are similar atoms (as in CO). In such substances, there is a very little energy difference between â€Å"†¦AB AB AB†¦Ã¢â‚¬  and â€Å".. †¦AB BA BA AB†¦.. † and other arrangements so that the molecules adopt the orientations AB and BA at random in the solid. This gives rise to some disorder, also known as frozen disorder, and consequently residual entropy.For example in case of CO, the measured residual entropy is 5 J K-1 mol-1 which is close to the value expected for a random structure Figure 1 (B) of the form â€Å"†¦Ã¢â‚¬ ¦CO CO OC CO CO OC OC†¦Ã¢â‚¬ . 14 Figure 1.

Most of the important buffer solutions generally consist of mixtures of weak acids and their salts or weak bases and their salts.These buffer solutions are known as acidic buffers and basic buffers respectively. If the pH of the buffer solution is less than 7, it is called an acidic buffer and if the pH of the buffer solution is greater than 7 it is called a basic buffer. Examples of some acidic and basic buffers are as given below Acidic buffer Basic buffer 1) Acetic acid and sodium acetate 1) Ammonium hydroxide and ammonium chloride 2) Formic acid and sodium formate 2) Ammonium hydroxide and ammonium nitrate pH of an acidic buffer A very common example of an acidic buffer is a mixture of acetic acid and sodium acetate.Acetic acid, being a weak acid, is very slightly dissociated, while sodium acetate being a salt is completely dissociated. The mixture thus contains acetic acid molecules as well acetate ions and sodium ions. At equilibr ium: CH3COOH(aq) H+ (aq) + CH3COO-(aq) Taking the negative logarithm on both the sides, we get 16 †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦(7. 39) In general, †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦(7. 40) It may be noted that the concentration of the acetate ions is taken to be almost equal to the concentration of the salt because the acetate ions coming from fully dissociated salt (here sodium acetate) suppress the ionization of the weak acid (acetic acid). This equation (7. 0) is called Henderson- Hasselbalch equation. According to this equation, the pH of an acidic buffer consisting of a mixture of a weak acid and its salt depends on the pKa of the acid, and the concentrations of the salt and acid in the mixture. If concentration of the salt is equal to that of the acid, then Buffer action of Acidic buffer The buffer action of an acidic buffer consisting of a mixture of acetic acid and sodium acetate can be explained in the following way. If we add small amount of HCl to the buffer solution it will ionise to give H+ ions. These combine with CH3COO- ions to form weakly ionized acetic acid.CH3COO-(aq) + H+(aq) ? CH3COOH(aq) + H2O(l) Since H+ ions get neutralised by CH3COO- ions, there will be no change in pH. On the other hand, if we add a few drops of NaOH to the buffer solution, it provides OH- ions which are neutralized by the acetic acid present in the mixture. 17 OH-(aq) + CH3COOH(aq) ? CH3COO-(aq) + H2O(l) Therefore the pH of the solution remains unchanged. pH of a Basic Buffer A very common example of a basic buffer is a mixture of ammonium hydroxide and ammonium chloride. Ammonium hydroxide being a weak base is very slightly dissociated, while ammonium chloride being a salt is completely dissociated.The mixture thus contains ammonium hydroxide molecules as well as ammonium ions and chloride ions. At equilibrium, NH4OH(aq) NH4+(aq) + OH-(aq) Taking the negative logarithm on both the sides, we get †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢ € ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦(7. 41) In general, †¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦Ã¢â‚¬ ¦(7. 42) 18 It may be noted that the concentration of the ammonium ions is taken to be almost equal to the concentration of the salt because ammonium ions coming from the fully dissociated salt (here ammonium chloride) suppress the ionization of the weak base ammonium hydroxide. This equation (7. 42) is called Henderson- Hasselblach equation. Further, pH can be calculated easily from pOH using Hence,It may be noted that pKa + pKb = 14 Buffer action of basic buffer The buffer action of a basic buffer consisting of a mixture of ammonium hydroxide and ammonium chloride can be explained in the following way. If a few drops of HCl are added to the buffer solution, it will ionise to give H+ ion which will combine with OH- ions to form H2O. H+(aq) + OH- (aq) ? H2O(l) Therefore, the addition of HCl will not change the pH. On the other hand, when a few drops of NaOH solution are added to the buffer solution, it would give OH- ions. These OH- ions combine with NH4+ ions present in the solution to form NH4OH, which is only slightly ionised.OH-(aq) + NH4+ (aq) ? NH4OH(aq) Hence, the addition of a base also will not change the pH. 19 EXERCISE 1. A certain buffer is made by mixing sodium formate and formic acid in water. With the help of equations explain how this buffer neutralizes addition of a small amount of an acid or a base. 2. A basic buffer is made by mixing ammonium hydroxide and ammonium nitrate in water. Explain how this buffer resists change in its pH on addition of a small amount of an acid or a base. 3. What would be the pH of a solution obtained by mixing 10 g of acetic acid and 15 g of sodium acetate and making the volume equal to 1 L.Dissociation constant of acetic acid at 25oC is 1. 75 x 10-5. 4. A buffer solution contains 0. 40 mol of ammonium hydroxide and 0. 50 mol of ammonium chloride to make a buffer solution of 1 L. Calculate the pH of the resulting buffer s olution. Dissociation constant of ammonium hydroxide at 25oC is 1. 81 x 10-5. Answers 3. pH = 4. 80 4. 9. 161 20 Class XII Unit 16: Chemistry in Everyday Life 16. 4. 2. 1. ANTIOXIDANTS Antioxidants are one of the important and necessary food additives. These compounds retard the action of oxygen on food thus reducing its speed of decomposition by oxidation. Hence they help in the preservation of food.These act as sacrificial materials, i. e. these are more reactive towards oxygen than are the materials they are protecting. They also reduce the rate of involvement of free radicals in the aging process. Examples: The two most familiar antioxidants used are butylated hydroxy toluene (BHT) and butylated hydroxy anisole (BHA) (Figure 1). These phenolic compounds are added to preserve fats in packaged food. Oxygen reacts preferentially with BHA or BHT rather than oxidizing fats or oils, thereby protecting them from spoilage. The addition of BHA to butter increases its storage life from mo nths to years.Sometimes, BHT and BHA are added in combination with citric or ascorbic acids to produce a more active synergetic effect. Figure 1: Butylated hydroxy toluene (BHT) and butylated hydroxy anisole (BHA) Sulphur dioxide and sulphites ( such as sodium sulphite, sodium bisulphite and sodium metabisulphite) are useful antioxidants for wine and beers, sugars syrups and cut, peeled or dried fruits and vegetables. They prevent or reduce their discoloration. 21 EXERCISE 1. Name one antioxidant commonly used to increase the storage life of butter. 2. Name one antioxidant used in wine and beers. 22a
