ESA engineers are proposing a technique to enable a digital satellite radio service for European drivers – without the need to launch a single new satellite into orbit.
Commercial digital satellite radio is already a reality in the United States, using a costly set of dedicated satellites. The rival American services allow subscribing drivers to choose between numerous near-CD quality radio channels without tune-out or static.
Two parallel ESA studies have examined a lower-cost method o
Report envisions a future cyberinfrastructure that will “radically empower” the science and engineering community
The critical needs of science and rapid progress in information technology are converging to provide a unique opportunity to create and apply a sustained cyberinfrastructure that will “radically empower” scientific and engineering research and allied education, according to the National Science Foundation (NSF)’s Advisory Committee for Cyberinfrastructure. The committee
A Penn State researcher has developed a faster method for more efficient sharing of widely distributed Internet resources such as Web services, databases and high performance computers.
Jonghun Park, assistant professor in Penn State’s School of Information Sciences and Technology (IST) who has proposed the protocol, says the new technology speeds up to 10 times faster the allocation of Internet resources.
“In the near future, the demand for collaborative Internet applications wi
Museum curators and researchers who need to view historical artefacts or works of art in museums and galleries such as the Louvre, the Uffizi and London’s National Gallery, should be able to save on their plane and train fares thanks to a unique project being undertaken by computer scientists at the University of Southampton.
The project, known as SCULPTEUR, involves building an advanced database to store three-dimensional representations of museum artefacts and works of art together wi
Huge data sets examined interactively yet remotely
A surgeon in New York who wants the opinion quickly of a specialist in Los Angeles probably would send medical MRI [magnetic resonance imaging] files as e-mail attachments or make them accessible in Internet drop zones. Unfortunately for patients on operating tables, extremely large files may take a half-hour to transmit and require a very large computer ( perhaps not available ) to form images from the complicated data. Additionally,
Representatives from 14 international, national, and regional organisations from around the world meeting in Brazil have agreed to form a World Federation of Science Journalists, recognizing the increasing international nature of science communication.
The new organization is designed to bridge scientists and society worldwide by creating a network for the exchange of information, improving access to scientific and technical sources and facilitating training and education of journalists par
Major international research programme on Life as learning
Mobile phones are the new learning tools of the future
Mobile phones look set to become an important new learning tool for the future. One of the projects under the umbrella of the Academy of Finland international research programme Life as Learning (or LEARN for short) is working on theoretical models and practical applications that will facilitate the use of mobile technology in learning. In charge of this project is Pro
A new optical antenna, developed by researchers at the University of Warwick, will bring significant benefits to credit card payments, wireless networks, household electronics and longer distance data transfer.
The device was developed by Professor Roger Green and Roberto Ramirez-Iniguez, in the University of Warwick`s Engineering Department. It applies techniques used to manipulate radio frequencies to select the incoming “signal frequencies” carried on infrared beams to produce the optica
Put aside images of World War II espionage and codebreaking. Today cryptography is vital to the security of a form of communication and commerce never imagined 60 years ago: the Internet. Researchers at Northwestern University now have demonstrated a new high-speed quantum cryptography method that uses the properties of light to encrypt information into a form of code that can only be cracked by violating the physical laws of nature.
In the open and global communication world of the Interne
As cable companies and Internet access providers compete for customers by offering broadband service, cable modems and digital subscriber lines (DSLs) as faster access to the Web, slower download speeds sometimes prompt greater user response than faster download speeds, a study says.

New research enables computers to name that tune
A team of British and American scientists claim a world’s first in online music recognition, paving the way for the musical equivalent of web search-engine Google; and the potential to resolve musical copyright disputes. Researchers at Queen Mary, University of London; King`s College London; Oxford University and the Universities of Indiana and Massachusetts have developed a new system which enables computers to recognise complex pieces
Telecommunications companies worldwide must make “fundamental adjustments” to their business models if they are to survive in the complex and highly competitive new economy, according new research by the Universities of Newcastle and Strathclyde, UK.
A research paper published in a special issue of the journal Telecommunications Policy (1), urges companies to sharply examine and revise their pricing policies to encourage greater revenues and reverse the recent stock market slump in telecommunica
The first complete map of drug related web-sites on the Internet is under construction. Dr Fabrizio Schifano and colleagues at St George`s Hospital Medical School in Tooting, London, will collect and analyse data from web-sites relating to the design and sale of recreational and illicit substances. The purpose is to provide healthcare professionals in the European community with as much information as possible on the latest drugs – drugs that are often unrecorded in medical textbooks.

Hope for shareholders; warning for salesmen
In these roller coaster times for the economy, there is qualified hope: operations researchers report that peoples’ reaction to a sequence of occurrences in which an initial event is unexpectedly reversed is more favorable if the first event is a loss than if it is a gain, according to a study in a journal of the Institute for Operations Research and the Management Sciences (INFORMS®). “Our research supports the casual observation that
More Internet information means more disinformation,warns a Dartmouth engineering professor
Why is the stock market fluctuating wildly these days? Is it poor earnings reports? Is it questionable accounting practices or CEO inefficiency? Or do investors trade frantically after they’ve read something on the Internet? If an investor reads a seemingly authoritative report about a company’s performance, he or she might be influenced to buy or sell stock.
Sometimes what
Viewing of internet ads does lead to future sales
Contrary to popular e-wisdom, measuring Internet banner ads only by the number of times that viewers click through is faulty, according to a paper presented today at a conference of the Institute for Operations Research and the Management Sciences (INFORMS®).
The paper contends that the more often consumers see online banner ads, the more likely they are to make a purchase, even if they don’t click through immediately to the
