TechAndComputer (Oct. 31, 2012) — Taking a close look at the steady flow of millions of 140-character messages per day generated on Twitter is akin to trying to take a drink from the torrent of a fire hydrant's discharge. But thanks to sophisticated software named in homage to the researcher, transfixed on a computer monitor, that it is designed to relieve -the "TwitterZombie" is helping researchers at Drexel collect tweets without being washed away.

Since tweets disappear from...

New tool aims to ensure software security policies reflect user needs

  • PDF
TechAndComputer (Oct. 30, 2012) — Researchers from North Carolina State University and IBM Research have developed a new natural language processing tool that businesses or other customers can use to ensure that software developers have a clear idea of the security policies to be incorporated into new software products.

Specifically, the research focuses on access control policies (ACPs), which are the security requirements that software developers need to bear in mind when...

An open platform improves biomedical-image processing

  • PDF
TechAndComputer (Aug. 31, 2012) — Ignacio Arganda, a young researcher from San Sebastián de los Reyes (Madrid) working for the Massachusetts Institute of Technology (MIT) is one of the driving forces behind Fiji, an open source platform that allows for application sharing as a way of improving biomedical-image processing. Arganda explains that Fiji, which has enjoyed the voluntary collaboration of some 20 developers from all over the world, has become a de facto standard that assists...
