Web users who stick to one or two search engines and learn those well will have better results for their queries than users who try the same query or various engines, a Penn State researcher says.

“There are no wholesale rules about structuring a query that will work on multiple search engines,” said Bernard J. Jansen, assistant professor of information sciences and technology (IST). “And what works on one engine, such as narrowing a query, can have the opposite effect on other search engine

Drivers are four times more likely to have an accident if they use a mobile phone on the road. However, using a “talking windscreen” rather than a traditional mobile phone while driving could reduce this risk, and so help to prevent accidents, according to Oxford University research just published in Psychological Science.

A growing body of evidence shows that using a hands-free phone is as problematic for drivers as using a hand-held phone. It is probably the distraction of a driver´s atte

The explosive growth in mobile phones has been supported by a similar growth in the underlying networks of base stations used to connect calls. This has created headaches for network administrators charged with keeping an increasing numbers of base stations active at all times. Now a convenient new power and management cabinet allows administrators to manage the entire operation of base stations remotely, reducing time and costs and improving range.

One of the most unusual, yet persistent, problems television broadcasters face is what Tom Grimes calls “unitentional defamation.”

“This takes place when TV news viewers’ memory plays tricks on them and they end up ’remembering’ the facts of a TV news story in a way that defames an innocent person portrayed in the news story,” said Grimes, the Ross Beach research chair in the A.Q. Miller School of Journalism and Mass Communications at Kansas State University.

New digital tools

To survive and thrive in this century, business leaders need to hardwire new technologies into their playbooks to create enduring enterprises.

Many factors, from the need to export beyond national borders to the inexorable shift to intellectual capital, are driving change, but none is more important than the rise of the Internet and digital technologies. Like the steam engine or the assembly line, the Net and digital technologies have already become an adva

Although ATMs are convenient, they have taken away from personal interaction during bank transactions. But according to research by a Kansas State University professor, consumers still feel as though they have relational benefits with self-service technology, much as they do when doing business with a human.

The research by Kevin Gwinner, an associate professor of marketing at K-State, shows that the attributes of self-service technology, such as the Internet, kiosks and ATMS, are indirect

Über Log-Files und Monitoring-Tools können Analysen über das Besucher-Verhalten durchgeführt und wichtige Erkenntnisse betreffend der eigenen Website gewonnen werden. Diese sind jedoch ausschliesslich quantitativer Natur und lassen wichtige qualitative Aspekte des Internet-Auftritts unberücksichtigt.

New research from the University of Alberta has found that an online business can benefit from listing its competitors’ products, even if some of those comparisons are unfavourable for the firm.

Dr. Gerald Haeubl, the Banister professor of electronic commerce at the U of A’s School of Business, investigated how digital agents, such as the Internet, influence the online shopping experience. Surprisingly, he found that when a company lists its competitors’ prices of identical products—even if

Study also reports users lose trust in systems that give phony ratings Online “recommender systems” are used to suggest highly rated selections for book buyers, movie renters or other consumers, but a new study by University of Minnesota computer science researchers shows for the first time that a system that lies about ratings can manipulate users’ opinions. Over time, however, users lose trust in unscrupulous systems. The Minnesota research group, led by professors Jos

Das Fraunhofer-Institut für Produktionstechnologie IPT stellt auf der HANNOVER MESSE 2003 vom 7. bis 12. April 2003 ein neues Verfahren zum Präzisionsblankpressen optischer Komponenten aus anorganischen Gläsern vor. Auf einem Gemeinschaftsstand mit der IVAM NRW e. V. (Interessengemeinschaft zur Verbreitung von Anwendungen der Mikrostrukturtechniken) zeigt das Fraunhofer IPT in Halle 6, Stand C22, verschiedene strukturierte Glasoptiken, die mit der Abformtechnologie am Institut hergestellt wurden.

A new group of ceramic materials could lead to more reliable and clearer microwave communication signals, according to engineers at South Bank University, London, speaking at the Institute of Physics Congress at Heriot-Watt University on Wednesday 26 March.

A small ceramic component made from a dielectric material is fundamental to the operation of filters and oscillators in several microwave systems, such as satellite TV receivers, military radar systems, Global Positioning System (GPS) dev

Industry experts at Search Engine Watch recently named Vivísimo the Web’s Best Meta-Search Engine for its ability to instantly organize search results into a computer-generated “index.” The software behind Vivísimo’s search engine can also be applied to any collection of documents, in languages ranging from English and German to Arabic and Korean.

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.

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.

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
