Control system research is entering a new era, which may be considered a milestone in the history of Systems and Control. The traditional framework of a control system structure — i.e. plant, sensor, actuator and a controller — presents a number of limitations to some current research, i.e. (a) System to be controlled comprise network of subsystems; (b) Control task is achieved by a network of distributed...
This paper presents a case study of three different five bit multidimensional constellations using Orthogonal Chaotic Vector Shift Keying (OCVSK); a two dimensional chaotic QPSK equivalent scheme (QCSK), a spherical Triakis Icosahedral scheme and a five dimensional hypercubic constellation. The optimal duration for each signal chip within the scheme is determined, in the light of the perceived noise...
A detailed and a simplified model of a lesioning electrode was made using the finite element method. 15 simulations of the lesioning procedure were performed for each model and the resulting lesion volumes were compared in order to investigate if the simplified model is adequate. The simplified model resulted in a very slight overestimation of the volume compared to the detailed model. It was thus...
Bio-heat transfer, - heat transfer affecting living organism under the influence of blood perfusion -, is given great and increasing attention in medicine today. One reason is the increasing use of thermal treatment methods in for example heart- and neuro-surgery. Analysis and modelling of the thermal aspects is frequently carried out at every stage of device and method development, as it exhibits...
