Dielectric elastomers are a promising group of smart materials, which finds application within many fields such as soft robotics, wave-energy harvesting, and loud speakers. A dielectric elastomer consists of a thin, stretchable polymer film sandwiched between two compliant electrodes. ... En savoir plus

In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ...

Medical accelerators, in particular Cyclotrons, are used to accelerate charged particles to tens of Mega electron Volts (MeV) of energies. These high energy particles then used to produce isotopes for medical application such the system located at king Faisal Specialist Hospital and ... En savoir plus

In the EMPIR project ADVENT the Scanning Microwave Microscopy (SMM) is investigated. The SMM is a still rather novel member of the family of scanning probe microscope. It has attracted a lot of attention recently, because this instrument can be used to characterize various electrical ... En savoir plus

The continuous and intensive use of squirrel-cage induction motors in the modern industry, has in some cases caused a serious deterioration of the electrical insulation in the windings of the machine, generating as a consequence internal short-circuit failures, the effects on the ...

Estimation of both single-ended (SE) and differential-pair (DP) impedances of high-speed PCB-traces/interconnects, vias and connectors is very important for the high-speed PCB (layout) design. This is because, the mismatch in line-impedances/improper line-termination results in a ... En savoir plus

Most of existing material representations [1], even including the dynamic hysteresis and iron losses [2], ignore local microscopic non-uniformities. These concern the magnetic structure (domains and walls [3]) and are mainly due to surface effects, anisotropy and exchange [4]. One ... En savoir plus

Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... En savoir plus

As part of the High Luminosity Large Hadron Collider a number of magnets is to be installed for the purpose of enhancing the performance of the Large Hadron Collider. The 11 T superconducting dipole is a magnet type that utilizes the Nb3Sn superconductor. A number of these magnets will ... En savoir plus
