Super Mini Computer

U.S. software company Computer Boffins launch the smallest, measuring only one millimeter. The world's smallest computer includes an ultra low-power microprocessor, pressure sensor, memory, super-thin battery. In addition, the computer is also equipped with solar cells, wireless antenna that can transmit data to an external reader.

The team of researchers from the University of Michigan, United States, said, "although this is a mini super computer in the world, but the device in the computer is very impressive." Our work is very unique. We're thinking about a complete system where all the low-power components according to when attached to computer chips. We can collect data, store it and send it. All applications on the system is not limited. "This isis the first system of complete millimeter -scalecomputing ,"said Professor Dennis Sylvester .

Currently these mini computers are used for applications in medical systems. The use of computers has focused on pressure monitors that are designed to be embedded in the eye to be able to track the spread of glaucoma, a potentially blinding disease. But someday, this mini-computer technology can be used to track pollution, monitoring the structural integrity, and conduct supervision, or make any object can be tracked. Of course, as long as the computer is not lost not lost.

World's Fastest Computer

China surpassed the United States in terms of supercomputer technology. It is based survey engine speed computer in the world to be assessed by experts from Germany and the United States.

Tianhe-1 which means 'Milky Way' capable of reaching speeds of computing 2570 trillion calculations per second, and placed on the throne the first in a survey of 500 supercomputers.

However, Tianhe - 1 which is used in Tianjin using computer chips made by U.S. companies.

While the previous champion, the computer used Jaguar U.S. government in Tennessee, slipped in second place. Jaguar is able to move with speed of 1750 trillion calculations per second.

While China's other kompter system, nebulae, in Shenzhen was in third position.

Although the U.S. still dominate, at least more than half the category's fastest 500 computers, but China managed to enter 42 in the rankings system was. China even beat other technological superpower - Japan, France, Germany, and England.

This is not the first time the U.S. digital king's crown was taken over Asian countries. In 2002, Japan made machine with a force equivalent to 20 U.S. top computer combined into one.

Lenovo IdeaCentre C300

With a beautiful design and complete facilities, Lenovo IdeaCentre A600 is an ideal representation of a PC AiO. Not long ago, the vendor re-release of his newest family IdeaCentre labeled C300. Can be traced from its name if this product is set as a downgraded version of the A600. However, the design aspect remains a mainstay of Lenovo. This time they gave perwajahan attraction with classical motifs frame.

Class differences with the "brother" immediately apparent when we looked in the hardware specifications. To suppress the price, Lenovo uses Intel's Atom processor. But instead of using a type of N270 or N280 is actually intended for the netbook, C300 carrying a targeted N330 Intel for nettop. Naturally, if the performance was quite rushed C300 compared to other PC selevelnya AiO. Especially if you just used for standard computing activities.

Shown with 20-inch screen, C300 is well suited to satisfy the users of the multimedia side. The availability of an internal DVD drive into an advantage compared to C300 class competitors who generally only provide an external optical device.

But when tested, the ability to play HD video files, not as smooth as the way of hope. In some sections, the resulting picture somewhat broken. It does not matter if the play is a standard multimedia files such as AVI, WMV, and MP4.

Intrigued with its 3D performance, we played the game Doom 3 with the C300. The result? It turned out pretty good. Much more smoothly than when playing HD video.

Can biomolecular computer Logical Thinking

Tom Ran and Shai Kaplan of the Weizman Institute's Biological Chemistry designing a sophisticated program for biomolecular computer that allows a computer they can be made in logical thinking.

Ran and Kaplan find new ways to make computers easy to use, even when doing tasks complex calculations. They created a computer is also designed to be able to answer difficult questions.

Big News Networks, Friday (16/10/2009) launch, actually in 2001 Ran and Kaplan had been introduced DNA computing system that can be programmed automatically.

Then, the latest version of the computing system was developed back in 2004. At that time, the computer system is used to mix the compound in a test tube to release the molecules to destroy the cancer.

Biomolecular computer system is now further developed in order to perform millions of calculations in parallel tasks.

BenQ nScreen

Market All-in-One PC (AiO PC) who still do not discourage new BenQ unveils steps simple desktop PC nScreen labeled. As AiO PC, nScreen look attractive appearance with a curve of the eye-catching. The model is available in a choice nScreen screen 18.5 "(i91) and 21.5" (i221). Especially for i221 series, added to the handset device supports voice communication via Skype (VoIP) is more practical.

Like desktop PCs, nScreen also serve as a standard USB connection, LAN, audio, and the internal speaker for multimedia support lightly. This mini PC also provides a 1.3-megapixel webcam and WiFi features to support communications via the Internet so easily. She exclaimed, nScreen interface is made simple by only includes a power button that serves to adjust the volume level.

BenQ claims the PC super nScreen as practical because it only takes 3 easy steps to activate it. IMac-like physique with a weight of less than 4.2 kg, making nScreen not need large space and power efficient.

Compared to other PC AiO models that have been circulating in the market, nScreen much cheaper because it only sells for U.S. $ 550 for the type i91 (18.5-inch screen). These are included with the keyboard and mouse. The use of components of the entry-level class is not too tight allegedly the cause of the price of this PC is more sloping.

Yes, wearing only nScreen AMD Sempron processor speed of 1.5 GHz 210U and graphics card ATI Radeon X1200 onboard, any optical drive is still optional. Composition is what causes nScreen less than ideal for demanding applications like 3D Max. Galva Technologies parties also explained that nScreen is designed for light application and Internet activity that was concerned with the speed as the main thing.

Doubts could arise among consumers, because this package AiO products are often not possible to upgrade. This then ditepis BenQ, that the product actually allows the user nScreen upgrade. Enough with the rear lid and process nScreen to hard disk or memory can be done without membutuhan screwdriver.

Computer algorithm to decipher ancient texts

Researchers in Israel say they have developed a computer program that can decipher previously unreadable ancient texts and possibly lead the way to a Google-like search engine for historical documents.

The program uses a pattern recognition algorithm similar to those law enforcement agencies have adopted to identify and compare fingerprints.
But in this case, the program identifies letters, words and even handwriting styles, saving historians and liturgists hours of sitting and studying each manuscript.

By recognizing such patterns, the computer can recreate with high accuracy portions of texts that faded over time or even those written over by later scribes, said Itay Bar-Yosef, one of the researchers from Ben-Gurion University of the Negev.

"The more texts the program analyses, the smarter and more accurate it gets," Bar-Yosef said.

The computer works with digital copies of the texts, assigning number values to each pixel of writing depending on how dark it is. It separates the writing from the background and then identifies individual lines, letters and words.

It also analyses the handwriting and writing style, so it can "fill in the blanks" of smeared or faded characters that are otherwise indiscernible, Bar-Yosef said.

The team has focused their work on ancient Hebrew texts, but they say it can be used with other languages, as well.

The team published its work, which is being further developed, most recently in the academic journal Pattern Recognition due out in December but already available online.

A program for all academics could be ready in two years, Bar-Yosef said.

And as libraries across the world move to digitize their collections, they say the program can drive an engine to search instantaneously any digital database of handwritten documents.

Uri Ehrlich, an expert in ancient prayer texts who works with Bar-Yosef's team of computer scientists, said that with the help of the program, years of research could be done within a matter of minutes.

"When enough texts have been digitized, it will manage to combine fragments of books that have been scattered all over the world," Ehrlich said.

Shapes of DNA have been used to enhance the production of circuits for next-generation computer chips

Researchers reporting in Nature Nanotechnology have now shown how to get engineered "DNA origami" to self-organise on silicon.

The origami can be designed to serve as a scaffold for electronic components just six billionths of a metre apart.
Making chips with components closer together leads to smaller devices and faster computers.
The six nanometre mark is nearly eight times better than the current industry produces.
Several research groups have shown that DNA itself can be used to store or manipulate data, and the juggling of DNA in a test tube or within bacteria has been shown to solve simple computational tasks.
The current method, by contrast, leverages the ability to design DNA strands into regular shapes such as triangles.

Shapely

The computer industry would like to make use of next-generation materials with favourable electronic properties such as carbon nanotubes or nanowires.Such structures are tiny and difficult to manipulate, but the chemical groups hanging off DNA helices could be used as anchor points for them.
Those anchor points can be as little as six nanometres (nm) apart, making these DNA-bound circuit components smaller and thus faster than can currently be produced.The current industry standard for etching electronic components from larger structures - a so-called "top down" approach - has components at a distance of 45nm.

What makes the technique particularly useful is that the regular shapes of the circuit-loaded DNA origami allows them to fit neatly into shaped pits the researchers bored into silicon or carbon using standard techniques.This self-assembly occurs when a liquid filled with the origami is put in contact with the etched surfaces in what the authors call a case of "bottom-up keys" fitting into "top-down locks".

Because the eventual placement of the components puts them so much closer, the approach could lead to computers that are both smaller and faster.However, the motivations are also economic - industry-wide shifts to smaller components are phenomenally expensive to the manufacturers.

"The combination of this directed self-assembly with today's fabrication technology eventually could lead to substantial savings in the most expensive and challenging part of the chip-making process," said Spike Narayan, a science and technology manager at IBM's Almaden research centre.
Fuller integration of the technique could take as much as 10 years, IBM said.
