Optical Wireless Technologies for Broadband Communications
Today’s information exchange depends on the transmission of data, voice and multimedia across the telecommunication networks. Optical wireless broadband communication represents one of the most promising approaches for addressing the emerging broadband access market. It offers low start-up and operational costs, high security, rapid deployment, high fibre-like bandwidths where no licence is needed. On the Read more...
The Energy Problem and the Interplay Between Basic and Applied Research
The situation facing our planet could hardly be more dire: There’s increasingly dangerous competition among nations for ever scarce energy resources, and climate change is racing ahead of predictions. Although Steven Chu believes “We are getting close to where it’s very nervous time,” he also sees “reason for hope.” Just as science in the 1970s Read more...
Statistical techniques for fraud detection, prevention, and evaluation – Lecture
The talk begins by setting the context: fraud is defined and its breadth outlined; figures are given showing how significant fraud is; and different areas of fraud are examined, including health care fraud, banking fraud, and scientific fraud. The particular data analytic challenges of banking fraud are described and illustrated in detail. These include the Read more...
The Sparse Grid Method
The sparse grid method is a special discretization technique, which allows to cope with the curse of dimensionality to some extent. It is based on a hierarchical basis and a sparse tensor product decompositon. Sparse grids have been successfully used to solve partial differential equations in the past and, more recently, have been shown to Read more...
How to say "No" to a robot
This describes an integrated robotic system for spatial understanding and situated interaction in indoor environments. Robot communication is performed using only natural language, but sometimes it needs more than a “natural” language to understand. Watch the video by clicking on the image: How to say “No” to a robot Hendrik Zender, Patric Jensfelt, Oscar Martinez Read more...
