A compact integrated CMOS circuit for temporal differentiation is presented. It consists of a high-gain inverting amplifier, an active non-linear transconductance and a capacitor...
We present ARWin, a single user 3D augmented reality desktop window manager, placing 3D user interfaces into a physical desktop workspace. We explain our design considerations and...
This paper describes a radial layout method for displaying B+ -tree data structures. We present an algorithmic framework for computing the node positions that result in a planar d...
This paper describes a visualisation tool, VlUM, designed to support users in scrutinising models of their interests, preferences and knowledge. We also describe MECUREO, a tool f...
Models of programming and debugging suggest many causes of errors, and many classifications of error types exist. Yet, there has been no attempt to link causes of errors to these ...
