In a hydraulic manifold block for construction machinery, spool valves are used to control the movement of the machine. Spool valves have two elements: a cylindrical barrel hole (1) in which a spool (2) slides. By moving the spool in the barrel hole, apertures open and close which ... En savoir plus
This presentation concerns a novel technique ("Indentation Plastometry") for the rapid and versatile measurement of the plasticity and strength characteristics of metallic materials using indentation data. The methodology has recently been developed by former scientists from the ... En savoir plus
IntroductionThe application of power ultrasounds in food dehydration processes have shown a good performance in terms of efficiency, energy reduction and quality of the final product, allowing also a reduction in the convective drying kinetics, and at lower temperatures than conventional ...

The following study was conducted to model the different behaviors of a material. The studied material is part of the elastomer’s family and is used in a wide temperature range from -55 ° C to + 135 ° C. This large temperature amplitude will generate behaviors strongly dependent on the ... En savoir plus
For the development of a Permanent Magnetic Synchronous Machine (PMSM), optimization of design variables, e.g. the size of an air gap, is performed. When applied to optical instruments in space environment, the motor has to be designed for ultra high vacuum (UHV) and cryogenic ... En savoir plus
Finite Element simulations are becoming an increasingly powerful tool in the transducer design process. The development of user-friendly software and predefined interfaces able to provide physics setup to predict the loudspeaker complex behavior helps designers in the product development ...

Power cables are of great importance in power transmission and distribution systems. Terminations and joints are the basic accessories of the power cables and they are required to make connections between cables or to an electrical apparatus. High voltage cables and cable accessories are ... En savoir plus
When a material is subjected to a sudden change in electric field, the polarization of the material takes a finite time to respond – this phenomenon is referred to as dielectric relaxation. Dielectric relaxation is critical to understanding the important analytic technique of impedance ... En savoir plus
Nitinol self-expanding stents are most commonly used to widen the passage of a restricted blood vessel. Unlike balloon-expandable stents, nitinol allows the stent to recover large strains caused by mechanical stresses due to its superelasticity. Self-expanding stents are first crimped to ...

Introduction: Design of a thermally driven actuator used in Micro Electro Mechanical Systems (MEMS) with two different metal materials is discussed. To achieve best performance of the thermally driven actuator in this work, it is desired to use a metal material with both high coefficient ... En savoir plus
