World Wide Web Consortium Issues XML Signature as a W3C Recommendation

Joint work with IETF produces XML-based solution for digital signatures, foundation for Secure Web services

The World Wide Web Consortium (W3C) has issued XML-Signature Syntax and Processing (XML Signature) as a W3C Recommendation, representing cross-industry agreement on an XML-based language for digital signatures. A W3C Recommendation indicates that a specification is stable, contributes to Web interoperability, and has been reviewed by the W3C Membership, who favor its widespread

Facial models allow "band-efficient" video communication

Is it possible to combine a three-dimensional wire model of a face with real pictures of the same face? And is it possible to get the computer that is forming the new image to follow the face even when the person in question makes sudden movements or partially covers her face with her hand? These are a couple of the research questions for the Image Coding Group at the Department of Electrical Engineering at Linköping University in Sweden. The aim is to find a new technology for information-efficient

"Electronic Tongue" tastes fluids.

Several years ago an “electronic nose” was developed at Linköping University in Sweden. It was based on a number of different gas sensors and programmed to differentiate between various substances in air. This nose is now being joined by a corresponding sensor for fluids, the “electronic tongue.” The principle behind the “electronic tongue” is that a number of electrodes are submerged in the fluid. When a current is turned on across the electrodes the response varies depending on the liquid’s content

Striped nanowires shrink electronics

Wires one-millionth of a millimetre wide change composition along their length.

Wires one-millionth of a millimetre wide that change chemical composition along their length, just as fruit pastilles change flavour along a packet, have been grown in the United States. These multi-flavoured nanowires can act as miniature bar-codes, diodes and light sources.

Fingerprinting euro coins

Many Europeans are now learning to deal with a new currency. But also cash dispensers and cigarette machines must distinguish clearly between euros, the old currencies and counterfeit money. A miniature computer now checks the coins by means of digital image processing.

For users of the new European currency, having adequate safeguards against forgery is a matter of great importance. The paper money incorporates features such as holograms, watermarks, a security thread, and embossed text to

Derrida`s deconstruction to help safety industry

A technique used by academics to analyse poetry may soon help industry to find out whether computer safety systems really ARE safe. In a novel example of interdisciplinary academic work, English literature meets computing science in an project to design a decision-making framework for the safety industry.

Newcastle University researcher Jim Armstrong, who holds a first degree in English Literature and a PhD in Computing Science, is investigating how the technique ‘deconstruction’ – usually

Seven-figure Funding To Develop Future Of Computing

The University of Abertay Dundee has been named as a key member of an international project, to develop new ways of delivering computer applications via the internet.

The 2.8 million euros (£1.8 million) scheme will see academics and business people from across Europe work together to develop the technology, which is set to revolutionise the way in which computer applications are accessed, delivered and updated for users across the globe.

First PROBA pictures promise wealth of environmental data

ESA’s new micro-satellite PROBA has captured its first test images of the Earth’s surface using its small but powerful optical instrument, just two months after its launch from the Indian equator.

PROBA (Project for On Board Autonomy), the size of a small box and in orbit 600 km above the Earth’s surface, has provided scientists with its first detailed environmental images thanks to CHRIS – a Compact High Resolution Imaging Spectrometer – the main payload on the 100 kg European spacecraft.

Algorithm makes tongue tree

New computer programme could settle literary debates.

To date, unlike us, computers have struggled to differentiate a page of Jane Austen from one by Jackie Collins. Now researchers in Italy have developed a program that can spot enough subtle differences between two authors’ works to attribute authorship 1 .

The program can tell a text by Machiavelli from one by Pirandello, Dante or a host of other great Italian writers. It constructed a language tree of the

Motion Sickness – could Virtual Reality help?

Playing virtual reality computer games could provide the answer to combating motion sickness.

Scientists are looking at how feelings of nausea can be induced in people who are put into a virtual reality environment. By putting them back into that environment on a frequent basis the researchers are hoping to find out if they become accustomed to the conditions and overcome the symptoms of motion sickness.

The research is being carried out by scientists at Loughborough Univers
