The flip side of salting winter roads

Swedish scientists have studied models to help road and bridge maintenance engineers work out how much damage salting the roads in winter might cause to steel-reinforced concrete structures.

Footwear forensics: CSI needs to tread carefully

A new computer algorithm can analyze the footwear marks left at a crime scene according to clusters of footwear types, makes and tread patterns even if the imprint recorded by crime scene investigators is distorted or only ...

Fast algorithm extracts, compares document meaning

A computer program could compare two documents and work spot the differences in their meaning using a fast semantic algorithm developed by information scientists in Poland.

Spot a bot to stop a botnet

Computer scientists in India have developed a two-pronged algorithm that can detect the presence of a botnet on a computer network and block its malicious activities before it causes too much harm. The team describes details ...
