FEM (Finite Element Method) modelling software such as COMSOL Multiphysics® can be a powerful tool for modelling the behavior and response of piezoelectric materials and devices [1]. Devices based on piezoelectric crystals are particularly well suited, because the polarization magnitude ... En savoir plus

Photonic crystals (PhC) are optical nanostructures that are widely known for their strong spatial and temporal confinement of electromagnetic radiation. Here, we study the resonant optical trapping of a single nanoparticle within a hollow circular photonic crystal cavity. The ... En savoir plus

To maintain same droplet size across parallel devices, new break-up strategies based on geometry are been studied. In this work, we model a geometrically-set droplet generator, in which the droplet break-up occurs by a block and break mechanism. In other words when the disperse phase ... En savoir plus

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these ... En savoir plus

Remote field eddy current (RFEC) technique is a method of detecting defects in ferromagnetic tubes. This is based on low frequency eddy current, which employs an exciter coil and a receiver coil separated by a characteristic distance. The exciter is fed with a low frequency sinusoidal ...

Steel tubes are widely used in industries. In order to ensure the safety and reliability of industrial processes, electromagnetic acoustic transducers (EMATs) based guided wave technology has been developed for inspecting stainless steel tubes regularly. Theoretical models and finite ... En savoir plus

Rotor blades for wind turbines are made of GFRP material. They have to be designed to withstand wind and weather over their approximately 20 years of lifetime. The ability to monitor the mechanical stress is crucial in order to reduce maintenance costs and to maximize operational ... En savoir plus

In the model silicon nanorods are designed as cantilever array and coated with thin film of aluminum or aluminum nitride, to be characterized, thus, adding a detectable mass and altering the cantilever resistance to bending. The simulated results show that when films of different ... En savoir plus

This poster presents the electric field flowing through an insulated cable due to a high frequency voltage pulse in the presence of water trees. En savoir plus

Woven composites with basalt reinforcement plain 1x1 are examined to define structural mechanics. Woven composites were created by the prepreg technology, 8 layers of plain-weave basalt fabrics were saturated by the precursor, polysiloxane matrix Lukosil®, and joint pressed during ... En savoir plus
