Computer Memory Takes A Spin in Research Supported by Magnet Lab

Date: 18/12/2010 | By: Krish

Newswise — Using unique equipment developed by the National High Magnetic Field Laboratory at The Florida State University, an international team of researchers has used the spin of atomic nuclei in silicon to store information for longer than a minute and a half. More remarkable still, the team showed that the information can be read out electronically — a key step toward the development of faster conventional computers and superfast “quantum” computers.

The research was published Friday, Dec. 17, in the journal Science. Co-authors on the landmark paper are Johan van Tol, an associate scholar/scientist at the magnet lab; Gavin Morley of the London Centre for Nanotechnology; Dane McCamey of the University of Utah and University of Sydney; and Christoph Boehme of the University of Utah.

As demand for smaller and faster electronics increases, many scientists are focusing their efforts in the emerging field of “spintronics,” where the magnetic character, or spin, of electrons and nuclei are used to store information. While other researchers have shown that spin information can be processed in silicon, the material on which modern electronics and computing is based, until now, no effective way to both store and read out the information has been found.

“Finding a system compatible with silicon, the main material used in the semiconductor industry, is particularly useful as it has the potential to be incorporated into existing technology,” said McCamey, lead author of the Science paper. “We could then integrate spin-based information storage and processing devices onto a single chip.”

This is a new way of storing energy, said Boehme, a senior author on the paper.

“The length of spin memory we observed is more than adequate to create memories for computers,” he said.

Adequate, yes. But feasible? Not anytime soon, the authors caution. The nuclear spin storage-and-read-out apparatus works only at a few degrees Kelvin, or just slightly above absolute zero — the temperature at which even atoms almost stop moving. And it must be surrounded by high magnetic fields roughly 200,000 times stronger than Earth’s.

“Yes, you could immediately build a memory chip this way, but do you want a computer that has to be operated at 458 degrees below zero Fahrenheit and in a big national magnetic laboratory environment?” Boehme said. “First we want to learn how to do it at higher temperatures, which are more practical for a device, and without these strong magnetic fields to align the spins.”

The researchers used unique equipment for controlling electronic and nuclear spins in high magnetic fields and at very low temperatures to achieve their findings. The equipment was developed and built by van Tol and colleagues in the magnet lab’s Electron Magnetic Resonance user program.

“The high magnetic fields we use enable the electron spins to be lined up, initializing them so they are ready to store information,” van Tol said. “We now show that we can line up the nuclear spins too.”

“Electrical detection of electron spins is also the leading approach for detecting quantum information in silicon,” Morley added. “Future experiments could use this method to study quantum information stored in nuclear spins.”

The study was funded by the National High Magnetic Field Laboratory, the National Science Foundation, the Australian Research Council, Britain’s Engineering and Physical Sciences Research Council, and the Royal Commission for the Exhibition of 1851, a British funding agency led by Prince Philip.

The National High Magnetic Field Laboratory develops and operates state-of-the-art, high-magnetic-field facilities that faculty and visiting scientists and engineers use for research. The laboratory is sponsored by the National Science Foundation and the state of Florida.

HR interview question

Date: 17/12/2010 | By: Krish

Tell me about yourself ?
Start with the present and tell why you are well qualified for the position. Remember that the key to all successful interviewing is to match your qualifications to what the interviewer is looking for. In other words you must sell what the buyer is buying. This is the single most important strategy in job hunting.

So, before you answer this or any question it's imperative that you try to uncover your interviewer's greatest need, want, problem or goal.

To do so, make you take these two steps:
Do all the homework you can before the hr interview to uncover this person's wants and needs (not the generalized needs of the industry or company)

As early as you can in the interview, ask for a more complete description of what the position entails. You might say: “I have a number of accomplishments I'd like to tell you about, but I want to make the best use of our time together and talk directly to your needs. To help me do, that, could you tell me more about the most important priorities of this position? All I know is what I (heard from the recruiter, read in the classified ad, etc.)”

Then, ALWAYS follow-up with a second and possibly, third question, to draw out his needs even more. Surprisingly, it's usually this second or third question that unearths what the interviewer is most looking for.

You might ask simply, "And in addition to that?..." or, "Is there anything else you see as essential to success in this position?:

This process will not feel easy or natural at first, because it is easier simply to answer questions, but only if you uncover the employer's wants and needs will your answers make the most sense. Practice asking these key questions before giving your answers, the process will feel more natural and you will be light years ahead of the other job candidates you're competing with.

After uncovering what the employer is looking for, describe why the needs of this job bear striking parallels to tasks you've succeeded at before. Be sure to illustrate with specific examples of your responsibilities and especially your achievements, all of which are geared to present yourself as a perfect match for the needs he has just described.

History of gmail&its few features...

Date: 16/12/2010 | By: Krish

Gmail, known as Google Mail in Germany, was made available to the public by Google on 1 April 2004, after extensive rumors of its existence during testing. Owing to the April Fool's Day release, the company's press release aroused skepticism in the technology world, especially since Google had been known to make April Fool's jokes in the past, such as PigeonRank. However, they explained that their real joke had been a press release saying that they would take offshoring to the extreme by putting employees in a "Google Copernicus Center" on the Moon. Jonathan Rosenberg, Google's vice-president of products, was quoted by BBC News as saying, "We are very serious about Gmail
In 1 April 2005, Exactly one year after the initial release, Gmail increased the mailbox size to 2 GB, advertising it as 2GB plus and introduced some other new features, including formatted editing which gave users the option of sending messages in HTML or plain text.
The application gives Gmail its own custom menu system and the site displays attachments, such as photos and documents in the application.
In 28 January 2007, Google Docs & Spreadsheets was integrated with Gmail, providing the capability to open attached Microsoft Word DOC files directly from Gmail.

Yahoo! Mail (shortened to Y! Mail) is a free web mail service provided by Yahoo!. It was inaugurated in 1997. According to comScore, Yahoo! Mail is the second largest web-based email service with 273.1 million users as of November 2010.[1]

Currently, Yahoo! offers two versions of Yahoo! Mail: an Outlook-like Ajax interface based upon code the company acquired from Oddpost in 2004, as well as the traditional full-page-scroll "Yahoo! Mail Classic," which continues the availability of the simpler 1997-2006 interface for the brand's considerable installed base of users. In early 2008, Yahoo! started offering unlimited mail storage to its users, in response to heated competition in the free-web mail market segment.[2]

On June 27, 2009, Yahoo! Messenger was integrated with Yahoo! Mail Beta.[3] This means that Messenger and Mail are together in one place, allowing users to connect instantly with others who are online, switch between email and chat, with no download or setup required. This new feature is now available for Mail Classic.

History of Infosys

Date: 13/12/2010 | By: Krish

Infosys Technologies Limited is a leader in software development and was co founded by N.R. Narayana Murthy and a group of seven IT professionals in the year 1981 with an investment of $1000. He emerged as the company's chairman and CEO and is regarded as a great manager because of his numerical abilities and Western style of management. It has created several firsts in Indian industry like being the first Indian company to be listed on NASDAQ in 1999 and the first to provide employee stock options plan (ESOP).

The company opened its first international office in USA in 1987. It became a public limited company in 1992 and offered its IPO in three of the nine Indian exchanges in 1993. It received its ISO 2001 certification in 1993 and opened other development centers in India in 1995.

By 1995 the firm was worth $200 million, had 900 employees and annual revenue of $20 million. It opened its first European office in United Kingdom in 1996. Infosys established its headquarters in Bangalore as there the workforces were not required to be unionized, benefits to the workforce were relatively a minor cost, and there was a huge potential for profit.

The late 1990s was a time for exponential growth and the main reason for this was its offshore software development model. By 2000 its market capitalization was more than $20 billion.

In 2003 it established subsidiaries in China and Australia. In 2004 it crossed $1 billion in revenue. In 2006 its revenue crossed $2 billion and it completed 25 years

IBM Unveils New Chip; Heats Up Supercomputer Battle

Date: 12/12/2010 | By: Krish

IBM unveiled a new technology that uses pulses of light instead of electrical signals to transfer data between chips that will bolster its plans to create an Exaflop supercomputer, capable of one million trillion calculations per second.

Recently crowned fastest supercomputer in the world, the Chinese Tianhe-1A, clocks in at 2.57 petaflops. A petaflop is equivalent to thousand trillion operations per second.

The new chip technology evolved by IBM is called CMOS Integrated Silicon Nanophotonics. The new technology integrates optical and electrical devices on the same silicon chip, thus translating electric signals into photons thus speeding communication between chips which is faster than transferring data through embedded copper wires.

The major issue that slowed optical communication was the delay caused in converting electrical signals into optical signals. Thus with putting both optical and electrical devices on the same chip the signals can be converted faster.
Dr. T.C. Chen, vice president, Science and Technology, IBM Research, said, "With optical communications embedded into the processor chips, the prospect of building power-efficient computer systems with performance at the Exaflop level is one step closer to reality."
