SURFACE-CONDUCTION ELECTRON-EMITTER DISPLAY (SED)
Surface-Conduction Electron-Emitter Display (SED):
A Surface-conduction Electron-emitter Display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction electron emitter emits electrons, that excite a phosphor coating on the display panel which is similar to the basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs can combine the slim form factor of LCDs with the high contrast ratios and can also refresh rates making the picture quality of CRTs better .The researches so far claim that the SED consumes less power than the LCD displays. The surface conduction electron emitter apparatus consists of a thin slit, across which electrons tunnel when excited by moderate voltages (tens of volts).
When the electrons cross electric poles across the thin slit, some are scattered at the receiving pole and are accelerated towards the display surface by a large voltage gradient (tens of kV) between the display panel and the surface conduction electron emitter apparatus. The SED display offer brightness, color performance and viewing angles on par with CRTs. However, they do not require a deflection system for the electron beam. Engineers as a result can create a display that is just a few inches thick which is still light enough for wall-hanging designs. The manufacturer can enlarge the panel merely by increasing the number of electron emitters relative to the necessary number of pixels. Since 1987, SED technology has been developing. Canon and Toshiba are the two major companies working on SEDs.

MAGNATORESISTIVE RAM (MRAM)
MAGNATORESISTIVE RAM (MRAM):
MRAM, the new breed of semiconductor memory uses magnetic properties to store data. This new kind of chip will compete with other established forms of semiconductor memories such as Flash memory and random access memory (RAM). Most engineers believe that the technology called magnetoresistive random - access memory (MRAM) could reduce the cost and power consumption of electronics for cell phones, music players, laptops and servers.
The feature, that makes MRAM an alluring alternative to other forms of semiconductor memories, is the way it stores data. For example, flash memory and random-access memory (RAM) hold information as electric charge. In contrast, MRAM uses the magnetic orientation of electrons to represent bits. Using MRAM, reading and writing of data can be done unlimitedly with in nanoseconds. MRAM can also hold the data without a power supply.

4G
4G:
The technology called 4G has redefined the whole concept of today’s sophisticated communication. According to the Wireless World Research Forum (WWRF), 4G is a combination of wired and wireless networks in computer, consumer electronics and communication technology systems based on the internet technology, that can merge applications like the Wi-Fi and WiMAX capable of transmitting at a speed ranging from 100 Mbps (in cell-phone networks) to 1 Gbps (in local Wi-Fi networks).
This collection of technologies and protocols delivers high quality of service at both ends and high point security. Officially named by IEEE as Beyond 3G (B3G) it provides with the lowest cost wireless network.
CELL PHONE VIRUSES AND SECURITY
CELL PHONE VIRUSES AND SECURITY:
As cell phones become a part and parcel of our life so do the threats imposed to them is also on the increase. Like the internet, today even the cell phones are going online with the technologies like the edge, GPRS etc. This online network of cell phones has exposed them to the high risks caused by malwares viruses, worms and Trojans designed for mobile phone environment. The security threat caused by these malwares are so severe that a time would soon come that the hackers could infect mobile phones with malicious software that will delete any personal data or can run up a victim’s phone bill by making toll calls.
All these can lead to overload in mobile networks, which can eventually lead them to crash and then the financial data stealing which poises risk factors for smart phones. As the mobile technology is comparatively new and still on the developing stages compared to that of internet technology, the antivirus companies along with the vendors of phones and mobile operating systems have intensified the research and development activities on this growing threat, with a more serious perspective.
SYNCML
SyncML:
The popularity of mobile computing and communications devices can be traced to their ability to deliver information to users when needed. Users want ubiquitous access to information and applications from the device at hand, plus they want to access and update this information on the fly.
The ability to use applications and information on one mobile device, then to synchronize any updates with the applications and information back at the office, or on the network, is key to the utility and popularity of this pervasive, disconnected way of computing.
Unfortunately, we cannot achieve these dual visions:
1. Networked data that support synchronization with any mobile device
2. Mobile devices that support synchronization with any networked data
Rather, there is a proliferation of different, proprietary data synchronization protocols for mobile devices. Each of these protocols is only available for selected transports, implemented on a selected subset of devices, and able to access a small set of net-worked data. The absence of a single synchronization standard poses many problems for end users, device manufacturers, application developers, and service providers.
SyncML is a new industry initiative to develop and promote a single, common data synchronization protocol that can be used industry-wide. Driving the initiative are Ericsson, IBM, Lotus, Motorola, Nokia, Palm Inc., Psion, Starfish Software. Additional companies are being recruited to join and participate.
The SyncML initiative recognized the worldwide need for one common data synchronization protocol. With the industry-wide proliferation of mobile devices and the evolution toward mobile devices as the major means of information exchange, remote synchronization of data will be of integral importance. The SyncML initiative, officially supported by well over 200 device manufacturers, service providers and application developers, is currently developing and promoting an open global specification for mobile data synchronization.
SMARTQUILL
Smartquill:
Lyndsay Williams of Microsoft Research’s Cambridge UK lab is the inventor of the Smartquill, a pen that can remember the words that it is used to write, and then transform them into computer text. The idea that it would be neat to put all of a handheld-PDA type computer in a pen came to the inventor in her sleep. “It’s the pen for the new millennium,” she says. Encouraged by Nigel Ballard, a leading consultant to the mobile computer industry, Williams took her prototype to the British Telecommunications Research Lab, where she was promptly hired and given money and institutional support for her project. The prototype, called SmartQuil, has been developed by world-leading research laboratories run by BT (formerly British Telecom) at Martlesham, eastern England. It is claimed to be the biggest revolution in handwriting since the invention of the pen.
The sleek and stylish prototype pen is different from other electronic pens on the market today in that users don’t have to write on a special pad in order to record what they write. User could use any surface for writing such as paper, tablet, screen or even air. The SmartQuill isn’t all space-age, though -- it contains an ink cartridge so that users can see what they write down on paper. SmartQuill contains sensors that record movement by using the earth’s gravity system, irrespective of the platform used. The pen records the information inserted by the user. Your words of wisdom can also be uploaded to your PC through the “digital inkwell”, while the files that you might want to view on the pen are downloaded to SmartQuill as well.
It is an interesting idea, and it even comes with one attribute that makes entire history of pens pale by comparison—if someone else picks your SmartQuill and tries to write with it- it won’t. Because user can train the pen to recognize a particular handwriting. Hence SmartQuill recognizes only the owner’s handwriting. SmartQuill is a computer housed within a pen which allows you to do what a normal personal organizer does. It’s really mobile because of its smaller size and one handed use. People could use the pen in the office to replace a keyboard, but the main attraction will be for users who usually take notes by hand on the road and type them up when returning to the office. SmartQuill will let them skip the step of typing up their notes.

General Essay Writing Tips
General Essay Writing Tips:
1. Step One: Brainstorming - The most important part of your essay is the subject matter. You should expect to devote about 1-2 weeks simply to brainstorming ideas. Having completed step one, you should now have a rough idea of the elements you wish to include in your essay, including your goals, important life experiences, research experience, diversifying features, spectacular nonacademic accomplishments, etc. You should also now have an idea of what impression you want to make on the officers.
2. Step Two: Selecting a Topic - After evaluating your essay topics with the above criteria and asking for the free opinions of your teachers or colleagues, and of your friends, you should have at least 1-2 interesting essay topics.
3. Step Three: Writing the Essay - Even seemingly boring topics can be made into exceptional admissions essays with an innovative approach.
Unfortunately, there is no surefire step-by-step method to writing a good essay.
But still following few steps can make the essay successful:
01 - Answer the question – Check what are all the questions that will arise from the Essay that you will present.
02 - Be original - Even seemingly boring essay topics can sound interesting if creatively approached.
03 - Be yourself
04 - Don't thesaurize your composition - For some reason, students continue to think big words make good essays. Big words are fine, but only if they are used in the appropriate contexts with complex styles. Think Hemingway.
05 - Use imagery and clear, vivid prose
06 - Spend the most time on your introduction - Expect officers to spend 1-2 minutes reading your essay. You must use your introduction to grab their interest from the beginning.
07 - Body paragraphs must relate to your introduction - Your introduction can be original, but cannot be silly. The paragraphs that follow must relate to your introduction.
08 - Use transition - You must use transition within paragraphs and especially between paragraphs to preserve the logical flow of your essay.
09 - Conclusions are critical - The conclusion is your last chance to persuade the reader or impress upon them your qualifications.
10 - Do something else
11 - Give your draft to others
12 - Revise, revise, and revise
In writing the essay you must bear in mind your two goals:
1. Allow for the evolution of your main topic.
2. Do not assume your subject must remain fixed and that you can only tweak sentences.
Editing takes time: Consider reordering your supporting details, delete irrelevant sections, and make clear the broader implications of your experiences. Allow your more important arguments to come to the foreground. Take points that might only be implicit and make them explicit. To persuade the officer that you are extremely worthy of and to make the officer aware that you are more than a GPA and a standardized score, that you are a real-life, intriguing personality.
