The eggshell method was introduced by F. Henrotte as a novel magnetic force computation method. It allows computation of the force by integrating the magnetic stress tensor over a shell surrounding the body of interest. We investigate the numerical properties of this method for current carrying wires, and permanent magnets immersed in two-dimensional stationary magnetic fields, discretized by ...

High-resolution imaging is useful in oil and gas exploration to identify producing fractures that can be in the millimeter thickness range. In principle, high-resolution imaging maybe achieved using “current injection” to measure the electrical conductivity of the formation. Two current injection devices are compared for possible use as Logging While Drilling (LWD)imaging: The ...

CdTe and GaAs 3D semiconductor radiation detectors for medical imaging have been simulated. This was done through coupling Monte-Carlo simulations of interacting of X- and γ-rays with matter (using PENELOPE) while computating the applied potential, weighting field, free charge carriers transport and electrodes Charge Induction Efficiency (CIE) with COMSOL Multiphysics. Since the continuity ...

The development and analysis of interconnects in inhomogeneous structures such as very large scale integration chips, printed circuit boards, and multichip modules are essential for next-generation electronic products. In this paper, we illustrate fast and sufficiently accurate computation of capacitance matrices of multilayered and multiconductor interconnects applying the finite element ...

Ferroelectric technology continues to attract significant interest due to its wide range of applications (capacitors, nonvolatile memories, accelerometers ...). In this work we present a finite element model of a ferroelectric. Piezoelectric and ferroelectric matrix are included. The coupling between the piezoelectric and ferroelectric parameters be introduced formally using a thermodynamic ...

Introduction: Medium voltage reclosers are representing nowadays an important link between transmission power systems and low voltage grids. With a high level of renewable energy penetration, the medium voltage networks are becoming bidirectional. Therefore, the associated switching devices must ensure the protection of newer types of power systems as well as new types of loads. The optimal ...

Contact electro-thermal phenomena are of great theoretical and technological interest to a large number of processing applications, such as spot welding, current-assisted sintering, electrical circuitry (switches) and motors. A model has been developed, aiming at predicting physical and metallurgical phenomena in a steel sample upon rapid heating induced by current pulse discharge. Electric pulse ...

State of the art proximity sensors are most often based on optical or tactile methods. Although these sensor systems are widely used (e.g. clamping protection) the reveal several drawbacks. Most optical sensors need a line of side whereas tactile sensors cannot be used to determine a distance to an approaching object. Capacitive sensing technology has proven to be an interesting alternative to ...
