Mobile Technology Essay Example for Free

Mobile Technology Essay Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. The most popular tablet at the moment is the iPad, by Apple. Tablets are available on the 3G and 4G networks. Contents 1 4G networking 2 Operating systems 3 Channel hogging and file sharing 4 Future of smartphone 5 External links 6 References 4G networking One of the most important features in the [4G] mobile networks is the domination of high-speed packet transmissions or burst traffic in the channels. The same codes used in the 2G-3G networks will be applied to future 4G mobile or wireless networks, the detection of very short bursts will be a serious problem due to their very poor partial correlation properties. Recent study has indicated that traditional multi-layer network architecture based on the Open Systems Interconnection (OSI) model may not be well suited for 4G mobile network, where transactions of short packets will be the major part of the traffic in the channels. As the packets from different mobiles carry completely different channel characteristics, the receiver should execute all necessary algorithms, such as channel estimation, interactions with all upper layers and so on, within a very short time to make the detections of each packet flawless and even to reduce the clutter of traffic. Operating systems Many types of mobile operating systems (OS) are available for smartphones, including: Android, BlackBerry OS, webOS, iOS, Symbian, Windows Mobile Professional (touch screen), Windows Mobile Standard (non-touch screen), and Bada. Among the most popular are the Apple iPhone, and the newest Android. Android is a mobile operating system (OS) developed by Google. Android is the first completely open source mobile OS, meaning that it is free to any cell phone carrier. The Apple iPhone, which has several OSs like the 3G and 3G S, is the most popular smart phone at this time, because of its customizable OS which you can use to download applications (apps) made by Apple like games, GPS, Utilities, and other tools. Any user can also create their own Apps and publish them to Apples App Store. The Palm Pre using webOS has functionality over the Internet and can support Internet-based programming languages such as Cascading Style Sheets (CSS), HTML, and JavaScript. The Research In Motion (RIM) BlackBerry is a smartphone with a multimedia player and third-party software installation. The Windows Mobile Professional Smartphones (Pocket PC or Windows Mobile PDA) are like that of a personal digital assistant (PDA) and have touchscreen abilities. The Windows Mobile Standard does not have a touch screen but uses a trackball, touchpad, rockers, etc. The original smartphone OS is Symbian, with a rich history and the largest marketshare until 2011. Although no single Symbian device has sold as many units as the iPhone, Nokia and other manufacturers (currently including Sony Ericsson and Samsung, and previously Motorola) release a wide variety of Symbian models each year which gave Symbian the greatest marketshare. Channel hogging and file sharing There will be a hit to file sharing, the normal web surfer would want to look at a new web page every minute or so at 100 kbs a page loads quickly. Because of the changes to the security of wireless networks users will be unable to do huge file transfers because service providers want to reduce channel use. ATT claimed that they would ban any of their users that they caught using peer-to-peer (P2P) file sharing applications on their 3G network. It then became apparent that it would keep any of their users from using their iTunes programs. The users would then be forced to find a Wi-Fi hotspot to be able to download files. The limits of wireless networking will not be cured by 4G, as there are too many fundamental differences between wireless networking and other means of Internet access. If wireless vendors do not realize these differences and bandwidth limits, future wireless customers will find themselves disappointed and the market may suffer setback. Future of smartphone The next generation of smartphones are going to be context-aware, taking advantage of the growing availability of embedded physical sensors and data exchange abilities. One of the main features applying to this is that the phones will start keeping track of your personal data, but adapt to anticipate the information you will need based on your intentions. There will be all-new applications coming out with the new phones, one of which is an X-Ray device that reveals information about any location at which you point your phone. One thing companies are developing software to take advantage of more accurate location-sensing data. How they described it was as wanting to make the phone a virtual mouse able to click the real world. An example of this is where you can point the phones camera while having the live feed open and it will show text with the building and saving the location of the building for use in the future. Along with the future of a smart phone comes the future of another device. Omnitouch is a device in which applications can be viewed and used on your hand, arm, wall, desk, or any other everyday surface. The device uses a sensor touch interface, which enables the user to access all the functions through the use of finger touch. It was developed at Carnegie Mellon University. This device uses a projector and camera that is worn on the persons shoulder, with no controls other than the users fingers. Acknowledgment I have taken efforts in this project.

Crude Oil Essay -- Papers

Crude Oil Crude oil is a complex mixture of hydrocarbon molecules formed over millions of years when the remains of microscopic sea creatures trapped in sediments were converted by heat and pressure into crude oil. The most abundant of these mixtures are the ones containing hydrogen and carbon only. These hydrocarbons can take on a number of different forms, i.e. alkanes, alkenes and alkynes. They vary in size and shape and viscosity. By manipulating these chains of hydrocarbons you can create any number of useful substances as they are very adaptable. However there are lots of compounds that also contain some of the following; oxygen, sulphur or nitrogen. The purer hydrocarbon compounds are the most required for these produce a higher temperature when they are burned which is the primary use for it as it generates an excess amount of energy when burned and therefore is a useful fuel. The other compounds with sulphur or nitrogen also have a high energy when burned but they have a negative side-effect as they make sulphur dioxide and nitrogen dioxide when burned and these compounds contribute towards acid rain. Crude oil has to be refined by fractional distillation to separate the short productive hydrocarbon chains from the longer, less useful ones before the compounds can be put to good use. Fractional distillation is a technique that relies on the difference in boiling points of the chains of hydrocarbons to separate them. It is so specific that it can separate the substances from each other even when there is only a small amount of difference between the boiling points of the substances. The crude oil is heat... ...ne, which are used to manufacture chemicals. Or the residual from the distillation tower is heated 482Â °C, cooled with gas oil and rapidly burned in a distillation tower. This process reduces the viscosity of heavy weight oils and produces tar. The other method of cracking is called Catalytic Cracking and it uses a catalyst to speed up the cracking reaction. Catalysts include zeolite, aluminium hydrosilicate, and bauxite. The hydrocarbons (only from the oil fraction) are heated in the same way but the catalyst speeds up the reaction by lowering the boiling point of the substance and allowing high molecular mass alkanes to break into many low molecular mass alkanes and some alkenes. Because the bond breaking happens randomly, many different forms of the substances are made, i.e. cyclo or branched isomers.
