Friction is present in almos every motion control application an effect the quality of the position, velocity or force control. This influence depends on the controls strategy itself and on the compensation algorihms that can be added to improve the contro ...
It was in the first half of the 18th century when life sciences started to flourish in the independent republic of Geneva. However, it is difficult to identify a genuine school of developmental biologists during that era. Nevertheless, several prominent sc ...
What constitutes a good example in the context of teaching design patterns? How can instructors judge whether one example is better than another one for teaching a design pattern to students? How might an example be presented to best connect with students, ...
Forward Error Correction copes with packet losses, but at the expense of an increase of the end-to-end delay. By failing to take this into account, existing error control schemes for audio often lead to end-to-end delays larger than 150 ms, which has an im ...
Personal computing and communication devices such as computers, personal digital assistants (PDAs), and mobile phones are moving to their next generation in which the end user will be able to access a multitude of information with a single device either lo ...
We focus on packet video delivery, with an emphasis on the quality of service perceived by the end-user. A video signal passes through several subsystems, such as the source coder, the network and the decoder. Each of these can impair the information, eith ...
We present a comparison of different two-step holographic recording schemes based on their multiplexing performance using a unified framework. The difference between the different schemes is mainly due to the energy levels and sources of the traps. The inf ...

A new system, Physilog, for ambulatory monitoring of movement is proposed and its applications in orthopaedic, physiology, angiology and quality of life are presented. Body accelerations were recorded by a portable measuring device. Significant parameters ...
This paper provides a time-domain feedback analysis of gradient-based adaptive schemes with emphasis on stability and robustness issues. It is shown that an intrinsic feedback structure, mapping the noise sequence and the initial weight guess to the a prio ...
