Kia, Best Buy, and Viacom are using new tools to mine comments on the Web to see what consumers really think of their brands
A prototype sensor consumes just a few nanowatts and could take glucose readings from the eye.
In the mid-1990s, Matteo Frigo, a graduate student in the research group of computer-science professor Charles Leiserson (whose work was profiled in the previous installment in this series), developed a parallel version of a fast Fourier transform (FFT). One of the most frequently used classes of algorithms in computer science, FFTs are useful for signal processing, image processing, and data compression, among other things.

La virtualización de dispositivos móviles está experimentando un alto crecimiento en su demanda, pero presenta diversos problemas, como la variedad de hardware y sistemas operativos que existen en el mercado, así como algunas prácticas corporativas de exclusividad como la que propugna Apple.
La consultora española Eptisa TI ha desarrollado el Buscador Federado del Ministerio de Política Territorial y Administración Pública, el mayor de Europa hasta la fecha, según la propia compañía, que abarca más de 350 portales web y da acceso a toda la información pública de la Administración General del Estado.
There is a controversy about the benefit of model-based software development in practice. Reliable and broadly spread research that analyses the status quo of model-based development and its effects on economics is still missing. This article describes the results of a global study by Altran Technologies, the chair of Software and Systems Engineering and the chair of Information Management of the University of Technology in Munich (TUM) which examines the costs and benefits of model-based development of embedded systems in the car industry.
At its most fundamental, computer science is about the search for better algorithms more efficient ways for computers to do things like sort data or filter noise out of digital signals. But most new algorithms are designed to run on serial computers, which process instructions one after another. Retooling them to run on parallel processors is rarely simple.
A new article written by a fellow at Rice University's Baker Institute for Public Policy calls on the intelligence community to jointly create a policy on cybersecurity and determine the degree to which the U.S. should protect intellectual property and national infrastructure of other nations. The author also comments on how aggressive the United States should be in its proactive cyber-spying activities.
