Evaluation of inverse field solutions with biomedical applications
H. Brauer, M. Ziolkowski, J. HaueisenWe applied minimum norm estimations using different regularization techniques to the solution of the biomagnetic inverse field problem. Using magnetic field data measured with a…
An iterative linearized optimization technique for non‐linear ill‐posed problems applied to cardiac activation time imaging
P. Wach, R. Modre, B. Tilg, G. FischerA promising approach for the solution of the electrocardiographic inverse problem is the calculation of the cardiac activation sequence from body surface potential (BSP) mapping…
Identification of hidden ferrous 3D objects using finite elements
C. Magele, W. Renhart, B. BrandstätterThe process of identifying unknown hidden objects by taking advantage of electromagnetic effects becomes more and more important. Clearing of mines or finding electrical…
Combined reconstruction techniques for geometrical and magnetic characteristics of thermonuclear plasmas
P. Bettini, A. Formisano, R. Martone, A. Stella, F. TrevisanThe equivalent currents method has proven to be particularly effective in the identification of plasma boundary in Tokamak fusion devices. Anyway, the ill‐posedness of the…
Synthesis of linear actuators
Aldo Canova, Giambattista Gruosso, Maurizio RepettoThe synthesis of electro‐mechanic actuators is formulated as a constrained optimization problem where some performance function of the device is to be met, subject to the…
A field‐based inverse algorithm for the identification of different height lightning return strokes
Amedeo Andreotti, Federico Delfino, Paola Girdinio, Luigi VerolinoAn identification procedure for lightning return strokes is proposed. It makes it possible to reconstruct the return stroke height‐dependent attenuation function making use only…
Techniques for the automatic optimisation of active shields
P. Girdinio, M. NerviThe present work is about the development of automatic techniques for the optimisation of active shields for stationary magnetic fields. An active magnetic shield is basically…
A comparison of two generalized response surface methods for optimisation in electromagnetics
K. Rashid, M. Farina, J.A. Ramirez, J.K. Sykulski, E.M. FreemanWhen dealing with problems entailing time consuming finite element solutions alternative methods are sought which can reduce the number of function calls whilst preserving…
Identification of magnetic fields by charged projectiles data
Massimiliano de Magistris, Alessandro FormisanoThe problem of direct measurement of magnetic fields is in several cases not trivial when the region of interest is not directly accessible, or when conventional probes could be…
A fast evolutionary method for identifying non‐inferior solutions in multicriteria shape optimization of a shielded reactor
P. Di BarbaWhen tackling the multicriteria optimization of an electromagnetic device, the accurate sampling of the Pareto optimal front implies the use of complex and time‐consuming…
Analytical and finite element design optimisation of a tubular linear IPM motor
N. Bianchi, A. Canova, G. Gruosso, M. Repetto, F. TonelThe optimisation of a tubular linear motor with interior permanent magnets is described. For a rapid design the whole process is divided in three parts: an analytical approach for…
An analytical process to size a flyback converter
J. Schutz, L. Gerbaud, J. Roudet, C. LarouciThe paper deals with the sizing of a flyback converter. The approach proposes to use symbolic calculation to perform sizing times, the accuracy and the number of parameters to…
Optimisation of electromagnetic devices with uncertain parameters and tolerances in the design variables
P. Alotto, P. Molfino, G. MolinariThe common approach to continuous and discrete optimisation problems in electromagnetics does not take into account uncertainties and variations of the design variables. Local…
Optimization of large electrical salient pole synchronous generators
Ivan Mandić, Milica Pužar, Marijan PetrinićThe designs of salient pole generators may differ considerably from one hydroelectric plant to another. Automatic optimization procedure is highly desirable, because the designer…
Multi frequency electrical impedance tomography
Bernhard Brandstätter, Hermann Scharfetter, Christian MageleElectrical impedance tomography (EIT) is a non‐invasive method to monitor conductivity changes in regions of the human body. Its robust, miniaturizable instrumentation makes EIT…
Shape optimization of GIS insulator barrier
Kemal Hot, Ivan MandicA gas insulated substation (GIS) barrier with conical insulators from a cast epoxy resin is optimized to withstand AC and DC stresses. The field distribution across insulators…
NDT image fusion using eddy current and ultrasonic data
G. Simone, F.C. MorabitoA data fusion approach to the classification of eddy current and ultrasonic measurements is proposed in a context of defect detection/recognition methods for non‐destructive…
2‐D inverse problems with applications to micro‐gravity and energy storage
A. Mailfert, O. Vincent‐ViryDeals with a way of designing structures of superconducting coils able to generate uniform flux densities, or uniform force field. An inverse methodology, which is valid for…
An optimisation process of power electronics applications
L. Gerbaud, E. Atienza, A. Bolopion, J. FandinoThe paper deals with the sizing of controlled converter applications, with possibly, closed control loops, by combining several tools. The approach proposes to use symbolic…
