With the development of atomic force microscopes that allow higher scan speeds, the need for data acquisition systems (DAQ) that are capable of handling the increased amounts of data in real time arises. We have developed a low cost data acquisition and sc ...
This paper proposes a globally distributed synchronization algorithm for wireless sensor networks. In the proposed scheme, there is a master node that controls the network synchronization and the other sensors periodically broadcast synchronization pulses; ...
Given three or four synchronized videos taken at eye level and from different angles, we show that we can effectively use dynamic programming to accurately follow up to six individuals across thousands of frames in spite of significant occlusions. In addit ...
This paper investigates video coding with wavelet transforms applied in the temporal direction of a video sequence. The wavelets are implemented with the lifting scheme in order to permit motion compensation between successive pictures. We improve motion c ...
The implementation of OFDM-based systems suffers from impairments such as in-phase and quadrature-phase (IQ) imbalances in the front-end analog processing. Such imbalances are caused by the analog processing of the radio frequency (RF) signal and can be pr ...
The effect of plasma elongation kappa on the sawtooth behaviour is studied in ohmically heated TCV plasmas up to values of kappa = 2.8. Above a certain value of kappa, which varies from 2.2 to 2.6 and depends on the current profile, the sawtooth oscillatio ...
Generally the classical control architecture used to carry out a robot position control is based on a classical industrial motion planner that needs encoders cabling and analog cabling to insure the regulation loop. This work proposes a Profibus PC based c ...
We address the problem of modeling received pulse trains in a multipath fading channel and of computing their exact spectrum. We propose a model based on point processes. Such model is very general, simple and tractable and it allows to account for various ...
This paper presents a new approach to model a transmission tower for lightning performance studies. It consists of representing each part of the tower by equivalent vertical and/or horizontal transmission lines as required. While horizontal line parameters ...
A design technique for implementing a low-voltage and low-power quadrature oscillator operating at radio frequencies is proposed. The oscillator utilises a cascade of four stages of capacitive-source amplifiers to generate balanced quadrature signals. The ...
