SeaMicro Puts Netbook Processors to Work in Super-Green Web Server Computing

June 17, 2010 By vani Leave a Comment

In tech time, three months is forever. At the end of March the end of March, we reported that researchers in Germany had developed an efficient supercomputer using discount parts intended for netbooks. And this week, previously stealth tech startup SeaMicro released a new high-performance server that puts that research to work.

SeaMicro’s SM10000 x86-server uses 512 Intel Atom processors — more commonly found in netbooks and other light-weight computing applications — to achieve massive computing power with a small energy footprint.

The server is optimized for performing internet-focused tasks, and CEO Andrew Feldman realized started work over three years ago on servers that would perform more efficiently for delivering thousands of small requests simultaneous rather than dealing with one big job at a time.

By shifting to smaller, more efficient processors in larger scale, SeaMicro says customers will save huge will lead to huge savings for customers: As the chart below shows, the lower the CPU utilization of the server, the more a company will save year over year, as unused processors are powered down to save energy.

Navy inducts stealth destroyer INS Kochi

September 19, 2009 By admin Leave a Comment

Kochi, Sep 18 (ANI): The Indian Navy today inducted a stealth destroyer of Kolkata class, INS Kochi, to boost its maritime capabilities and safeguard India’s interests.

Madhulika Verma wife of Chief of the Naval Staff, Admiral Nirmal Verma, named the second of the three Project 15-A stealth destroyers on September 18.

Mazagon Docks Ltd in Mumbai built the 6500-ton ship, named INS Kochi.

The ship has advanced stealth features, which make it less vulnerable to detection by enemy radar and will be fitted with state-of-the-art weapon systems which include the supersonic BrahMos surface-to-surface missile, the LRSAM Long Range Surface-to-Air Missiles and the MFStar multi-function radar system providing accurate data on surface and air targets.

In addition, four AK-630 rapid-fire guns and a medium range gun will boost the ship’s close-range defence capability.

The ships will also be fitted with indigenously developed twin-tube torpedo launchers and anti-submarine rocket launchers.

The NPOL developed Humsa-NG hull-mounted sonar, and two multi-role helicopters adding punch to the ship’s anti-submarine capability. The maximum speed of the ship is above 30 Knots.

The destroyer will be launched using the pontoon-assisted launch technique, to be employed for the first time in the history of indigenous warship building.

This technique helps in overcoming slipway/ draft constraints and permits launching of heavier vessels. (ANI)

Brits drinking more ‘by stealth’ – thanks to stronger booze

August 27, 2009 By admin Leave a Comment

London, August 27 (ANI): People are taking in more booze “by stealth”, thanks to stronger drinks that are on sale, according to an analysis of consumption in the UK.

Researchers Mintel, who headed the survey, found the alcohol consumption level per person had leaped by 10 per cent since last nine years despite steady drink sales.

The research firm suggested the change could be linked to wines and lagers that were boasting of stronger alcohol content than before, leaving people unaware of the changes, reports the BBC.

Mintel, that also used data from a series of sources such as the NHS and sales information from shops, bars and pubs, said the alcohol content of wine is now normally around 13 per cent as compared to an estimated 11 per cent in the past.

Premium 5 per cent lagers were also growing in popularity.

Jonny Forsyth, a senior drinks analyst at Mintel, said: “It may be that the majority of consumers are not aware of ABV (alcohol by volume).

“So despite a greater societal concern with being healthy leading to a decline in drinking penetration, by stealth we are drinking more pure alcohol than ever.”

Don Shenker, chief executive of Alcohol Concern, added: “Consumers have limited information to help them make healthy choices about their alcohol consumption.

“There is often no information about units and even rarer information about sensible drinking levels on the labels of alcohol products.

“The increasing strength of wines and beers means we are often drinking at harmful levels without realising it.” (ANI)

Scientists create first acoustic metamaterial ‘superlens’

June 27, 2009 By admin Leave a Comment

Washington, June 25 (ANI): A team of researchers at the University of Illinois (U. of I.) has created the world’s first acoustic “superlens,” an innovation that could have practical implications for high-resolution ultrasound imaging, non-destructive structural testing of buildings and bridges, and novel underwater stealth technology.

The team, led by Nicholas X. Fang, a professor of mechanical science and engineering at Illinois, successfully focused ultrasound waves through a flat metamaterial lens on a spot roughly half the width of a wavelength at 60.5 kHz using a network of fluid-filled Helmholtz resonators.

According to the results, the acoustic system is analogous to an inductor-capacitor circuit.

The transmission channels act as a series of inductors, and the Helmholtz resonators, which Fang describes as cavities that house resonating waves and oscillate at certain sonic frequencies almost as a musical instrument would, act as capacitors.

Fang said acoustic imaging is somewhat analogous to optical imaging in that bending sound is similar to bending light.

But, compared with optical and X-ray imaging, creating an image from sound is “a lot safer, which is why we use sonography on pregnant women,” said Shu Zhang, a U. of I. graduate student who along with Leilei Yin, a microscopist at the Beckman Institute, are co-authors of the research paper.

Acoustic imaging can be used for tumor detection.

“In the body, tumors are often surrounded by hard tissues with high contrast, so you can’t see them clearly, and acoustic imaging may provide more details than optical imaging methods,” said Fang.Fang said that the application of acoustic imaging technology goes beyond medicine.

Eventually, the technology could lead to “a completely new suite of data that previously wasn’t available to us using just natural materials,” he said.

In the field of non-destructive testing, the structural soundness of a building or a bridge could be checked for hairline cracks with acoustic imaging, as could other deeply embedded flaws invisible to the eye or unable to be detected by optical imaging.

“Acoustic imaging is a different means of detecting and probing things, beyond optical imaging,” Fang said.

Fang said acoustic imaging could also lead to better underwater stealth technology, possibly even an “acoustic cloak” that would act as camouflage for submarines.

“Right now, the goal is to bring this ‘lab science’ out of the lab and create a practical device or system that will allow us to use acoustic imaging in a variety of situations,” he said. (ANI)

Chinese navy spells out long-range ambitions

April 17, 2009 By admin Leave a Comment

BEIJING (Reuters) – China will accelerate development of warships, stealth submarines and long-range missiles as the country makes a stronger navy a priority in military modernization, a Chinese admiral told state media.

Admiral Wu Shengli said the Communist Party leadership had ordered the navy to upgrade preparedness to defend the nation’s expanding interests, Chinese newspapers reported on Thursday.

“The Party central leadership has demanded that the navy make preparedness for military struggle at sea a priority in national security strategy and military strategy,” Xinhua news agency cited Wu as saying in the interview first issued on its website (www.xinhuanet.com) on Wednesday.

“We must accelerate progress in developing key weapons equipment,” Wu added, singling out big warships, long-distance stealth submarines, supersonic jet fighters, and high-accuracy long-range missiles.

Chinese media have highlighted the government’s hopes to build an aircraft carrier, seen as the badge of a mature ocean-going power. But Wu’s remarks highlighted the country’s broader ambitions to expand its naval reach.

China’s navy had become an “ocean-going iron Great Wall” to “counter a range of security threats,” Wu said.

He gave the interview to highlight the 60th anniversary of China’s navy, which will be marked next Thursday with a ship parade. But his outline of Beijing’s ambitions also comes after recent friction in the South China Sea with a United States navy ship, and also while China is showing its expanding reach by joining anti-piracy operations off east Africa.

Wu, a member of the Central Military Commission, which steers China’s military forces, said the People’s Liberation Army Navy was becoming more adept at long-distance operations.

Chinese military plans have long centered on Taiwan, the self-ruled island close to the mainland coast that Beijing says must accept eventual reunification, by force if necessary.

But with China’s appetite for energy and resources increasingly dependent on distant sources, strategists have called for a navy that can protect the nation’s interests in distant seas.

“Training on high seas has become the norm,” Wu said.

But the PLA navy has a long way to go before it approaches U.S. naval power. China has about 290,000 navy personnel, many working on aged vessels. And even with new technology, China has some way to catch up in mastering joint operations.

India to enter elite club, Antony to lay keel of first indigenous aircraft carrier today

March 1, 2009 By admin Leave a Comment

Kochi, Feb 28 (ANI): India will join the elite club today and will become fourth country in the world to indigenously build its own aircraft carrier of 40,000 tonne plus.

Defence Minister A.K. Antony will lay the keel for country’s first indigenous aircraft carrier or air defence ship (ADS) at the Cochin Shipyard’s construction dock in Kerala today, marking the launch of the first phase of building the 40,000 tonne aircraft carrier.

The ADS will give a major boost to the indigenous defence industry and make the Navy a pure Blue Water Navy.

India becomes fourth country after naval powers of the world like US, Russia, and France to build a carrier with a 40,000 tonne displacement. The United Kingdom has also built its own aircraft carrier, but not such a huge size.

The project codenamed P-71 will initially cost Rs 3,260 crore, but the amount would increase with the progress of the project and as per requirements.

The aircraft carrier will be in the waters by October 2010, as per the phase I contract signed by its manufacturer Cochin Shipyard Ltd (CSL) with the Defence Ministry. The phase II of the contract will end with the delivery of the ship to the Navy by the end of 2014.

The aircraft carrier is the largest military vessel to be constructed at any Indian yard, boosting shipbuilding capability of the country.

The life of the carrier is 50 years and more than 70 percent of its design is indigenous. Apart from it, the construction is 100 percent indigenous, having 70 percent home made components.

The ship has a length of 260 m and max breadth of 60 m, draft of 8.4 m and a depth of 25.6 m. The vessel will be propelled by four LM 2,500 gas turbines, which enables the ship sail at a maximum speed of 28 knots. The ship will have two takeoff runways and a landing strip with three arrester wires.

The ADS has the maximum capacity to carry 30 fighter jets, comprising Russian MIG-29 K Fighters, indigenous Light Combat Aircraft, and Kamov-31 helicopters on board.

The carrier is built with steel produced by state-owned SAIL (Steel Authority of India ltd.) The Defence Research and Development Organisation (DRDO) and Hindustan Aeronautics Ltd. (HAL) are also contributing the project.

The Directorate of Naval Design, the only in-house design bureau in the world, has prepared the design of the ADS. Equipments to be fitted on the aircraft carrier are to meet special requirements of shock, vibration, noise, stealth, compactness in size and weight, the official said.

Brit defence chiefs under the scanner over submarine collision

February 17, 2009 By admin Leave a Comment

London, Feb.17 (ANI): Britain’s defence chiefs are facing an inquiry into the safety of the United Kingdom’s nuclear deterrent after British and French submarines, each laden with missiles powerful enough for 1,248 Hiroshima bombings, collided while submerged in the mid-Atlantic.

HMS Vanguard, the lead boat of Britain’s fleet of four V-class submarines armed with Trident nuclear missiles, limped back into its home port of Faslane in Scotland on Saturday showing significant damage. Witnesses said the hull was scarred with dents and scrapes.

The weather was rough in the middle of the night of 3 and 4 February when the British submarine, which was carrying 135 crew, struck Le Triomphant, the flagship of the French nuclear strike force, destroying the French vessel’s fibreglass sonar dome, which juts out from the bow and, among other tasks, is supposed to detect other submarines.

In London, according to The Independent, the Ministry of Defence was forced to confirm the embarrassing collision between strategic allies after the French Navy posted details of the accident on its website.

Both countries insisted that neither the missile-launching capacity nor the nuclear safety of the submarines, carrying 265 crew and 32 intercontinental ballistic missiles, were affected.

Defence sources said the accident was the result of the “infinitesimal” coincidence that both submarines were operating at the same depth and location in the Atlantic.

Naval experts, who underlined that the two nuclear submarines were built with hulls designed to withstand huge pressures, expressed surprise that the sonar arrays of both had failed to detect either vessel.

Sonar technology is now so sophisticated manufacturers boast it can recognise a small fish.

That it does not seem to have been able to pick out a submarine nearly the length of two football pitches and the height of a three-storey building could be explained by the development of stealth technology, making the submarines less visible to other vessels.

Anti-nuclear campaigners said the two vessels had been moments from a potentially catastrophic accident, which could have resulted in the widespread release of radioactive material. (ANI)

eBay admits it needs to tackle sales of illegal knives

February 9, 2009 By admin Leave a Comment

London, Feb 9 (ANI): Online auction website eBay has admitted that it needs to take more precaution to stop the selling of illegal knives, which are illegal to carry in the UK.

The sale of the weapons came to light after researchers on the BBC’s Watchdog programme bought five knives, including a stealth knife and a dagger disguised as a pen.

The investigation comes just days after Home Secretary Jacqui Smith launched an initiative with more than 20 retailers to ensure that knives are sold responsibly.

“Trust is the engine of eBay and as the UK’s number one e-commerce site, we know we have a responsibility to keep the site safe for our buyers and sellers,” the Daily Express quoted an eBay spokesman as saying.

“Although the UK site did not have any illegal knives for sale by UK sellers, it was possible for UK buyers to see or purchase knives from international sellers.

“This should not have been possible and we have taken steps to close that loophole,” he added.

He also said that the company invested more than 6 million pounds every year “in developing the best technology possible to prevent anything from slipping through the net.”

“As the world’s largest marketplace we don’t handle items directly, so we use sophisticated technology to help us identify high risk or illegal items,” he said.

“Safety is our number one priority and we recognise we need to do more to protect our members.

“Therefore, we are reviewing our position with regards to the sale of all knives on eBay, including those currently permitted by law,” he added. (ANI)
