ANIMATION

Animation is the art of creating moving images with using computers. It is a sub field of computers graphics and animation. Increasingly it is created by means of 3D computer graphics, though 2D computer graphics are still widely used for low bandwidth and faster real-time rendering needs. Sometimes the target of the animation is the computer it self, but it sometimes the target is another medium, such as film.

It is also referred to as CGI (Computer-generated imagery or computer-generated imaging), especially when used in films. To create the illusion of movement, an images is displayed on the computer screen then quickly replaced by a new image that is similar to the previous image, but shifted slightly.

This technique is identical to how the illusion of movement is achieved with television and motion pictures. Computer animation is essentially a digital successor to the art of stop motion animation of 3D models and frame-by-frame animation of 2D illustrations. For 3D animations, objects are built on the computer monitor and 3D figures are rigged with a virtual skeleton. For 2D figure animations, separate objects and separate transparent layers are used, with or without a virtual skeleton.

The the limbs, eyes, mouth, clothes, etc. of the figure are moved by the animator on key frames. The differences in appearance between key frames are automatically calculated by the computer in a process known as tweening or morphing. Finally, the animation is rendered. For 3D animations, all frames must be rendered after modeling is complete. For 2D vector animations, the rendering process is the key frame illustration process. while tweened frames are rendered as needed. For pre-recorded presentations, the rendered frames are transferred to a different format or medium such as film or digital video.

ENCRYPTION IS SAFE FROM FUTURE QUANTUM COMPUTERS?

One of the themes of Dan Brown’s The Da Vinci Code is the need to keep vital and sensitive information secure. Today, we take it for granted that most of our information is safe because it's encrypted. Every time we use a credit card, transfer money from our checking accounts -- or even chat on a cell phone -- our personal information is protected by a cryptographic system
But the development of quantum computers threatens to shatter the security of current cryptographic systems used by businesses and banks around the world.
“We need to develop a new encryption system now, before our current systems -- such as RSA -- becomes instantly obsolete with the advent of the first quantum computer,” says Prof. Oded Regev at Tel Aviv University’s Blavatnik School of Computer Science. To accomplish that, Prof. Regev has proposed the first safe and efficient system believed to be secure against the massive computational power of quantum computers and backed by a mathematical proof of security.
Secure for Centuries
Prof. Regev stresses it is imperative that a new cryptographic system be developed and implemented as soon as possible. One reason is that current information, encrypted with RSA, could be retroactively hacked in the future, once quantum computers are available. That means that bank and other financial information, medical records, and even digital signatures could instantly become visible.
“You don’t want this information to remain secure for just 5 or 10 years until quantum computers are built,” says Prof. Regev. “You want it to be safe for the next century. We need to develop alternatives to RSA now, before it’s too late.”
New Cryptographic System
Cryptographic systems are used to transmit secure information such as bank and online transactions, and typically rely on the assumption that the factoring problem is difficult to solve. As a simplified example, if the number 3088433 were transmitted, an eavesdropper wouldn’t be able to tell that the number is derived from the factors 1583 and 1951. “Quantum computers can ‘magically’ break all of these factoring-based cryptographic systems, something that would take billions of years for current computers to accomplish,” Prof. Regev explains.

The current gold standard in encryption is the universally used RSA cryptosystem, which will be instantly broken once quantum computers are a reality -- an event predicted to happen as early as the next decade. To replace RSA in this new reality, Prof. Regev combined ideas from quantum computation with the research of other leaders in the field to create a system that is efficient enough to be practical for real-world applications. Prof. Regev’s work was first announced in the ACM Symposium on Theory of Computing and will appear in the Journal of the Association for Computing Machinery. His work has now become the foundation for several other cryptographic systems developed by researchers from Stanford Research Institute, Stanford University, and MIT. Its potential real-world applications are extensive, ranging from banking transactions to eBay and other online auctions to digital signatures that can remain secure for centuries.

THE FUTURES SUPER FAST COMPUTER

Computers which use light to process large amounts of data faster than ever before are just one of many groundbreaking potential applications of a new £6 million research programme at Queen’s University Belfast and Imperial College London, launched September 1, 2009.
The Engineering and Physical Sciences Research Council (EPSRC) is funding the two universities to establish a world-leading research programme on the fundamental science of so-called ‘nanoplasmonic devices’
Nanoplasmonic devices’ key components are tiny nanoscale metal structures - more then 100 times smaller than the width of a human hair – that guide and direct light.

The structures have been tailor-made to interact with light in an unusual and highly controlled way. This means they could one day be used to build new kinds of super-high-speed ‘optical computers’ – so named because they would process information using light signals, instead of the electric currents used by today’s computers.

At present, the speed with which computers process information is limited by the time it takes for the information to be transferred between electronic components. Currently this information is transferred using nanoscale metallic wires that transmit the signals as an electric current.

To speed up the process, the scientists at Queen’s and Imperial hope to develop a way of sending the signals along the same wires in the form of light.

In order to achieve this, they are developing a raft of new metallic devices including tiny nanoscale sources of light, nanoscale ‘waveguides’ to guide light along a desired route, and nanoscale detectors to pick up the light signals.

Similar approaches may also help in the development of devices for faster internet services.

Professor Anatoly Zayats from the Queen’s University’s Centre for Nanostructured Media who leads the project said: “This is basic research into how light interacts with matter on the nanoscale. But we will work together with and listen to our industrial partners to direct research in the direction that hopefully will lead to new improved products and services that everyone can buy from the shelf.”

Professor Stefan Maier, who leads the research team at Imperial added: “This is an exciting step towards developing computers that use light waves, not electrical current, to handle data and process information. In the future these optical computers will provide us with more processing power and higher speed. This will also open the door to a world of possibilities in scientific fields at the interface with the biosciences, and perhaps even in the world of personal computing.”

The project is also supported by INTEL, Seagate, Ericsson, Oxonica, IMEC and the National Physics Laboratory.

Researchers at the Fraunhofer Researach Institution for Electronic Nano Systems ENAS have developed a battery the weighs less then 1 gram and is less than 1 millimeter thick. The battery, which can be fprinted in a process similar to silk-screening shirts, could power bank cards or other slim application carriers. " The battery is environment-friendly as it contains no mercury. Its voltage of 15.V lies within the normal range. By placing several batteries in a row, voltages of 3V,4.5V and 6V can also be achieved.

All in one mobile phone charger.

After months of negotiations with hte European Commission, major producers of mobile phones have finally agreed to develop a standard for phone charging based on the Micro USB interface. The companies that signed the MoU include Apple, LG, Motorala, NEC , Nokia, Qualcomm, Research in Motion, Samsung, Sony Ericsson and Texax Instruments.
With this agreement, consumerswill be able to charge mobile phones anywhere from the new common charger. This also means considerably less electronic waste, because people will no longer have to throw away chargers when buying new phones. The large majority of phones will charge within two hours with the new common chargers, says the EU. Only in combination of a large battery with a small charger, the phone will charge within six hours.

AUTOMOBILES

DEFINITION:By definition an automobile or car is a wheeled vehicle that carries its own motor and transports passengers. The automobile as we know it was not invented in a single day by a single inventor. The history of the automobile reflects an evolution that took place worldwide.

It is estimated that over 100,000 patents created the modern automobile. You can point to the many firsts that occurred along the way to producing the modern car; and with that goal in mind, highlighted below are articles, biographies, time lines, and photo galleries related to the history of the automobile and its many inventors.

FASTEST SUPER COMPUTER

A scientist of Indian origin has created a new supercomputer, called Cystorm which can carry out 28.16 trillion calculations per second.
Cystorm, a sun Microsystems machine, was developoed by Mr SrinivasAluru from the Iowa state University. The 3,200 computer procesor cores that power Cystorm makes it perform 28.16 trillion calculations per second, which is five times the peak of CyBlue, an IBM Blue Gene\L supercomputer that's been in campus since early 2006 and users 2,048 processors to do 5.7 trillion calculations per second.
According to Mr Aluru, Mr Ross Martin Mehl, professors of computer Engineering and the leaders of the cystorm project, the new machine also scores high on a more realistic test of a supercomputer's actual performance:15.44 trillion calculations per second.

EVM technology can tamper?

Electronic Voting Machine :
(EVM technology)

Hardware

Inadequately secured hardware can be subject to a physical Tampering. Some critics, such as the group "Wij vertrouwen stem computers niet" ("We do not trust voting machines"), charge that, for instance, foreign hardware be inserted into the machine, or between the user and the central mechanism of the machine itself, using a main in the middle attack, and thus even sealing DRE machines may not be sufficient protection. Claim is countered by the position that review and testing procedures can detect fraudulent code or hardware, if such things are present, and that a thorough, verifiable chain of custody would prevent the insertion of such hardware or software.

Software

Security experts, such as Bruce Shenier demanded that voting machine source code be publicly available for inspection.Others have also suggested publishing voting machine software under a free software license is done in Australia.

Suggestions for protection

In December 2005 the US Election Assistance Commission unanimously adopted the 2005 Volantary voting system guidelines which significantly increase security requirements for voting systems and expand access, including opportunities to vote privately and independently, for individuals with disabilities. The guidelines will take effect in December 2007 replacing the 2002 Voting System Standards (VSS) developed by the Federal Election Commission.

Some groups such as the Open voting Consortium that to restore voter confidence and to reduce the potential for fraud, all electronic voting systems must be completely available to public scrutiny.

Also proposed is the requirement for use of open public standards and specifications such as the Election Markup Language(EML) standard developed by OASIS and now under consideration by ISO. These can provide consistent processes and mechanisms for managing and performing elections using computer systems.

E-paper's green credentials will boost adoption

The use of electronic paper, also known as 'e-paper,' is increasing as a result of its ultra-low power consumption, a similar user experience to real paper and 'green' benefits, according to a report from market research firm Gartner. E-paper is a display medium intended to mimic the appearance of ordinary ink on paper while being rewritable.
Gartner said that despite disadvantages of poor colour and refresh rate characterists, e-paper will hve significant benefits over other display media and positively impact the traditional paper market, the retail display sector, a number of consumer markets and the office environment in years to come.
One of the key drivers for e-paper adoption is the way it is continuously evolving to include new technologies. Recent additions include touchscreen, wireless connection and rewritable colour support capabilityinto devices using e-paper. Multiple e-book readers have also been introduced and applications of the technology are now expanding beyond e-book readers to include device displays for phones, clocks and watches.
Gartner believes that the cost of e-paper displays will need to fall further if it is to act as a viable mainstream alternative to print media, especially as the falling costs and increasing quality of alternative technologies-such as OLED and LCD - could moderate the growth potential of e-paper.

Wireless and Screenless MP3 Players

If you love listening to music but don't like to si glued to the computer,tangled in wires, take a sigh of relief. Companies are rolling out music systems that are not only wireless but also screenless. Targeting the youth are scend, Bose, Moser Baer and many more, making the competition indeed a fierce one. There are certainly more brand options and product features to choose from, to suit your needs and budget. When making your choice, establish whether you need an MP3 player for just listening to music or for storing photos and watching videos also.
Recently, Apple had re-designed its iPod Shuffle, which, unfortunately, did not stir up the youthy. Taking the opportunity, Sony has come up with an innovative wireless and screenless MP3 system, taking the music system directly into the earphones. Sounds innovative but does it work well? In fact, it's interesting to see devices shrinking in size.

Wireless and Screenless:

Wireless technology is not new but it is being usd by the music system makiers only recenlty. This technology can mainly be categorisd into two segments -Wi-Fi and Bluetooth. But the latest MP3 technology has revolutionised the market- it has done away with both.
Most of the wireless Mp3 players use the stereo Bluetooth technology but Sony has taken a leap further by building, the MP3 player inside the headphones. It has no sound modifications software, not even bass and treble controls. In fact, the only interesting it has is Zapppin, which has done away with the traditional display screen as well-yet another unique feature.
"Zappin scans though the music library by playing what the MP3 player thinks is the most recognisable clip of each song. The user can select short clips-about 4-15 seconds long-by pressing the jog dial while the music is playing,"explains Tomonori Moroda, division head, home audio video, Sony India.

Advantages and limitations

As the wireless MP3 players are targeted at the youth and the gymgoers, these may be an initial hit. " The great advantage of a wireless headset is that there are no wires to get rangled in. You have more freedom and can even move away from the MP3 while continuing to listen to music. However, there are certain obstacles for a widespread deployment of wireless devices due to lack of awareness and the cost factor as they are comparatively more expensive than the wired ones.
