Voice-over-IP (VoIP) has become an attractive alternative to the plain old telephone system, especially due to the much lower communication costs. However, there are several threats. In this document, several such threats are discussed. Moreover, we ask whether these systems could be used in environments with very high security demands as they for example exist in the Swiss army. ∗Computer Syst...

This paper describes a system that takes real-time user input to direct a robot swarm. The user interface is via drawing, and the user can create a single drawing or an animation to be represented by robots. For example, the drawn input could be a stick figure, with the robots automatically adopting a physical configuration to represent the figure. Or the input could be an animation of a walkin...

Many modern sensors used for mapping produce 3D point clouds, which are typically registered together using the iterative closest point (icp) algorithm. Because icp has many variants whose performances depend on the environment and the sensor, hundreds of variations have been published. However, no comparison frameworks are available, leading to an arduous selection of an appropriate variant fo...
