Usually, the quality of a vibrato can only be judged subjectively by voice experts. Until now, that is. A research group from Tel Aviv University has successfully managed to train a computer to rate vibrato quality, and has created an application based on biofeedback to help singers improve their technique.

A Yale research team has engineered a system with the potential for making the Internet work more efficiently, in which Internet Service Providers (ISPs) and Peer-to-Peer (P2P) software providers can work cooperatively to deliver data. The way people use the Internet has changed significantly over the past 10 years, making computers seem to run less efficiently and putting strain on the available bandwidth for transmitting data........ ]]> http://www.technology-blog.com/blogs/permalinks/5-2008/interactive-web-sites-draw-minds.html http://www.technology-blog.com/blogs/permalinks/5-2008/interactive-web-sites-draw-minds.html Wed, 09 Jul 2008 03:04:31 GMT The interactive look and feel of a corporate website could help shape positive perceptions about the organization if the site includes a likeable design and features that engage the target audience, particularly job seekers, as per media researchers. S. Shyam Sundar, professor of film, video and media studies at Penn State, and Jamie Guillory, formerly an undergraduate student at Penn State, are trying to understand how interactivity in websites influences the public perception of an organization. In prior studies of websites of political candidates, Sundar had observed that the candidates were rated more positively if their site had some interactive features, even though the sites had no new content, and the candidates held the same policy positions. But too much interactivity tends to turn off people........ ]]> http://www.technology-blog.com/blogs/permalinks/5-2008/dont-let-cyberspite-destroy-your-good-name.html http://www.technology-blog.com/blogs/permalinks/5-2008/dont-let-cyberspite-destroy-your-good-name.html Wed, 09 Jul 2008 03:04:31 GMT YOU buy a television on eBay. When it arrives, you eagerly unwrap it, only to find it is badly scratched. You return it, and leave a negative comment about the seller on the site. The next day, you find the seller has retaliated by posting a nasty comment about you, branding you as a time-waster. Suddenly, no one wants to sell to you and your reputation is in tatters........ ]]> http://www.technology-blog.com/blogs/permalinks/5-2008/biomedical-imaging-in-palm-of-hands.html http://www.technology-blog.com/blogs/permalinks/5-2008/biomedical-imaging-in-palm-of-hands.html Wed, 09 Jul 2008 03:04:31 GMT Researchers at Georgia Tech have developed a narrowband filter mosaic that will expand the uses and functionality of multispectral imaging-a technology that enables subsurface characterization.

As new top-level domains are added to the familiar.com,.info and.net, the algorithm* checks whether the newly proposed name is confusingly similar to existing ones by looking for visual likenesses in its appearance. Having visually distinct top-level domain names may help avoid confusion in navigating the ever-expanding Internet and combat fraud, by reducing the potential to create malicious look-alikes:.C0M with a zero instead of.COM, for instance........ ]]> http://www.technology-blog.com/blogs/permalinks/5-2008/a-new-role-for-cell-phones-in-telemedicine.html http://www.technology-blog.com/blogs/permalinks/5-2008/a-new-role-for-cell-phones-in-telemedicine.html Wed, 09 Jul 2008 03:04:31 GMT After launching a communications revolution, cell phones are talking up a potentially life-saving new role in telemedicine the use of telecommunications technology to provide medical diagnosis and patient care when doctors and patients are hundreds or thousands of miles apart.
