Information Technology

Time is running out for the clocks that make our computers tick. Scientists have developed a new generation of hardware and software based on the simpler designs of the 1950s.

Asynchronous, or clock-free systems, promise extra speed, safety, security and miniaturisation. The new designs work well in the laboratory and are only awaiting the development of software tools so that they can be produced commercially, says Professor Alex Yakovlev and fellow researchers in the Department of Computin

New devices boost optical networks

Several technical requirements must be met until data from computers, TV stations or telephone network providers can be transported via fiber-optic cables to their destinations. Specialists from Infineon Technologies leverage their combined expertise to continuously improve the conditions for today’s and tomorrow’s fiber-optic applications with innovative chip designs. For example, the German technology foundry has developed a special device that ca

An inventive idea from Dr Chris Solomon of the School of Physical Sciences at the University of Kent at Canterbury (UKC) has beaten top International competition and won first prize in the prestigious European Digital Information Contents (DICON) competition.

Dr Solomon who has an active research programme in forensic imaging and a longstanding interest in the computational modelling, encoding and recognition of the human face said: `I was truly impressed by the quality of some of the prese

In a joint project between the Technology Foundation STW and the energy agency Novem at Utrecht University, researchers have developed new silicon layers which are more stable and cheaper than the present amorphous silicon layers. The electronic properties of the present layers in laptop screens and solar cells deteriorate if the material is under ‘stress’, for example due to sunshine or a voltage.

Flat-panel displays and solar cells have a substrate of glass or plastic, which is coated with

+++ EURESCOM for the first time demonstrates seamless access with a PDA. +++

Premiere at the EURESCOM workshop `Wireless Access` in Heidelberg on 12 March: The EURESCOM project on `Bluetooth Access` presented the first PDA, which can seamlessly connect to different access networks, like LAN, Bluetooth, Wireless LAN, and GPRS.

In co-operation with the software company Birdstep from Norway and access point supplier Patria Ailon from Finland, the European project team implement

New algorithm exploits community structure of the web.

The web has spontaneously organized itself into communities. A new search algorithm that pinpoints these could help surfers find what they want and avoid offensive content.

Page builders can link anywhere. But they don’t, Gary Flake, of the NEC Research Institute in Princeton, and his colleagues have found. Instead, pages congregate into social groups that focus most of their attention on each other.
