Illegal immigrants and smugglers frequently use underground tunnels to avoid border security and checkpoints. In addition, the threat of international terrorism has recently made the effort to detect tunnels a national security priority. No single technology and sensing modality is ... En savoir plus

Electromagnetic (EM) flowmeters are important flow sensing devices across industries like oil and gas and power generation. The EM flowmeter works on the principle of Faraday’s law of electromagnetic induction. In short, when an ionic fluid like water flows through a pipe, in the ... En savoir plus

Cylindrical single or multi-turns coils and Spiral Flat multi turn coils are used in pulsed magnetic technologies for which both magneto-harmonic and transient magnetic analysis are required. The first are mainly used for tubular geometries and the second are preferred for sufficiently ... En savoir plus

This report addresses design of a PCB intended for use as a busbar integrated with multiple DC-link (rail) capacitors in a high power inverter. The geometry and current ratings are typical of a 50 kW unit operating at 60kHz in an intermittent mode. First, circuit aspects are analyzed. ... En savoir plus

Magnetic Resonance Imaging (MRI) is a powerful tool for exploring brain function, offering detailed insights into its structure and physiology. Combining MRI technology with electrophysiological recording systems can enhance comprehension of brain functionality through synergistic ... En savoir plus

The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... En savoir plus

The paper on EMC Simulation Analysis of Enclosures demonstrates a simulation method to analyze the shielding effectiveness of enclosures. From the early development stage on it is possible to analyze the effect of electromagnetic waves on shielding panels. Different types of openings ... En savoir plus

Due to the increase on the academic and industrial interest on thermal energy storage (TES) systems, the EU Horizon project HYSTORE is developing 4 different solutions. In these solutions, the use of thermochemical materials (TCM) and phase-change materials (PCM) are proposed. We ... En savoir plus

Electromagnetic shearing (EMS) is a high speed sheet metal shearing system where the workpiece is fractured under a pulsed electromagnetic force. It can be regarded as an extension of electromagnetic forming[1-2]. The basic shearing principle is that a huge repulsive electromagnetic ... En savoir plus

The use of Permanent Magnet Synchronous Machines (PMSM) as shaft generators is not new in marine vessels propulsion drive trains. Due to risk of fires in stator windings by internal faults, DNV GL requires the shaft generator to be electrically dead without losing propulsion. This ... En savoir plus
