This idea relies on the basic assumptions that the individual segments are measured simultaneously and that these signals obey certain symmetry rules with respect to the quantity to be measured. Unfortunately, both assumptions cannot fully be met in practice. This paper investigates the influence of asymmetry on a segmented capacitive angular sensor. Particular emphasis is placed on the noise introduced by a sequential rather than simultaneous measurement of the segments and by asymmetries due to the sensor geometry and fabrication tolerances. We find the measurement algorithm to be relatively robust provided that only one type of asymmetry dominates.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

Several digital filtering algorithms for distance relays have been proposed and some of them are used in practical applications. However nonlinear loads are becoming more and more common in electric power systems and that increases the corruption level of signals. For this reason, the study of digital filtering techniques for the extraction of fundamental components from highly corrupt voltage and current waveforms is of vital importance for the development of algorithms applied to the digital protection of transmission lines. The studied technique, proposed in this paper, is based on Walsh functions.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

These are based on a detailed analysis of the mechanisms at work on the generation of a class of nonlinear distortions, termed harmonic components. This leads to the derivation of formulae to calculate the number of harmonic components generated by any order of nonlinearity at the excitation frequencies during frequency response function measurements. Based on these formulae the classification of nonlinear distortions in harmonic and interharmonic components is compared against other methodologies on the classification of nonlinear distortions.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

Two superimposed stereo images are received simultaneously as a complex image and using a proper algorithm, disparities and depth of objects of the scene can be obtained. Two virtual cameras are created from this pseudo stereo vision system (PSVS) with exactly the same geometric properties, parameters and angular FOV of the real camera. This vision system has no moving parts, its construction is quite simple and it is mechanically robust. Thus, it is easy for this system to be mounted to the end effector of a robotic manipulator or to a mobile robot.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

The neural network is being trained with radiative transfer simulations, atmospheric measurements, and theoretical understandings about the physical properties and their signatures in satellite measurements. The learning and adjusting process will be very fast and automated. This study seeks to improve future remote-sensing algorithms by bridging visual understanding within the human brain and the retrieval techniques developed by researchers in scientific community.

The dependability, mainly illustrated in our approach by the availability of the process and by the reliability that characterizes the risk of incidents or accident occurrences, can be taken into account in the earliest stage of the design of the automation system. The main interest is that it allows the definition of reliable operational and functional architectures. To achieve the tasks allocation the used search method must integrate a notion of cost that includes both technological and functional aspects and those linked to the dependability. A genetic approach is used for the task allocation, giving a very satisfactory result in a reasonable computational time.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.

The reference is provided by objects with known position called masters. Two architectures are shown, the first uses one master, the second three masters. The one master architecture makes it possible to identify and locate all the sensors in space and to calculate for each of them the lowest energy transmission path to reach the master. The three master architecture locates each sensor when a transmission of information occurs by triangulation and can not optimize energy consumption during sensor communication. On the other hand, it is able to localize also moving sensors or to handle dynamically changing sensor topologies. The results show that the three master architecture is faster, but it implies an energy waste of 26 times greater than the one master architecture.","PeriodicalId":141111,"journal":{"name":"IMTC/2002.
