Geological repository for highly radioactive waste disposal is a system of engineered and natural barriers. The objective of this system is to contain and isolate waste and protect the environment and humans from ionizing radiation. For the evaluation of performance of engineered ... En savoir plus

This article reports the design of a high-power ultrasound system, capable of emitting acoustic radiation at 20kHz with SPL peaks up to 160dB at a distance of up to 1m. The main problem of high power airborne ultrasonic systems lies in the acoustic impedance mismatch between the radiator ... En savoir plus

During the hot extrusion process, a cylindrical pre-heated billet is inserted into a container and is forced by a hydraulic press to flow through a shaped die in order to obtain, as final product, a profile with a constant cross-section (Fig.1). Aluminum extrudates have become prominent ... En savoir plus

In order to reduce the environmental footprint of a serial production of head lamps, one lever is to replace and employ new materials, often requiring to redesign the product to ensure its mechanical and thermal resistance. In this context, this paper studies the modelling of the heat ... En savoir plus

This study presents a novel microfluidic chip integrated with biosensors and capillary microfluidics, specifically designed for target screening and precise fluid control. The capillary pumps facilitate spontaneous fluid delivery to the sensors, eliminating the necessity for external ... En savoir plus

The growing adoption of electric vehicles has led to increased exposure of cars to stray magnetic fields. To address this issue, inductive position sensors have emerged as a viable solution due to their inherent immunity to stray magnetic fields. Widespread adoption of the inductive ... En savoir plus

Currently, there are a number of promising applications of electromagnetic fields in medical diagnosis and therapy. Some, such as non-invasive monitoring of blood glucose concentration in patients with diabetes or temperature monitoring during hyperthermia, are in the phase of ... En savoir plus

To achieve the goals of the Paris Agreement and limit global warming below 2 K compared to pre-industrial level, significant energy savings in all fields of industries will be required. One example of energy intensive processes in industrial fabrication is heat treatment. The applied ... En savoir plus

Increasing energy demands in society have led to intensive fossil fuel usage, resulting in increasing carbon dioxide (CO2) emissions, one of the most significant greenhouse gases and major contributors to global warming. Considerable efforts have been made towards CO2 capture, storage, ... En savoir plus

Nowadays, surge protection devices are widely used in electrical grids to suppress over voltages during transient conditions caused by voltage surges and to prevent damages of industrial or household devices. The working principle is based on the initiation of an arc with a burning ... En savoir plus
