An electromagnetic horn is a device used in particle physics to produce a strong pulsed toroidal magnetic field and to focus charged particles toward a detector. A multiphysics analysis is performed to assess the stress level inside the horn structure. In steady state regime, the horn is submitted to a thermal static stress due to thermal dilatation. Then, every 80 ms a strong magnetic field ...

Like humans, horses can develop a variety of dental problems. Different equine diseases occur in different areas of the equine cheek tooth or its surrounding tissues. With a realistic simulation of a chewing cycle it can be possible to link mechanical phenomena such as high stress in distinct areas to commonly occurring diseases. According to different angles of the acting chewing force, ...

We consider a 3D boundary value problem arising in electrostatics. The potential is stimulated by current sources placed on a cross-section S of the domain. In many applications it is sufficient to know the potential in S. So, one is interested in an appropriate 2D model taking into account that the solution depends on the dimension of the domain. The idea is to find a corresponding 2D ...

This paper showed that: * SAG-MOCVD is a powerful tool to fabricate OEICs and is also effective to extract true surface kinetics during MOCVD. * GaAs-MOCVD process was examined by SAG analysis where it was seen that below 600ºC, surface kinetics shows non-linear behavior. * Surface reaction rate constant of adsorbed species was constant against offset angle, while adsorption equilibrium ...

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the Finnish spent fuel repository). A characteristic of these models lies in the need to integrate prior information, ...

Microcalorimetry for standardizing activities of radionuclide samples entails measurements of input power heat flow from the sample cell, with the radioactive sample compared to the reference cell under balanced conditions. The measurement is susceptible to noise due to drift and 1/f effects; thus, a better result might be expected with periodic insertion of the source into the sample chamber ...

The study of interaction of fluid with matter assumes great significance for most engineering applications. The flow can be either turbulent or laminar, and different types of interactions arise out of these flow. In the introductory undergraduate course of fluid mechanics, a typical demonstration for these interactions is the Reynolds pipe flow experiment. Instabilities of various types like ...

We have proposed a high performance MEMS based microstructure array of micropreconcentrator (microPC) for breath diagnosis of cancer biomarkers. Our microPC has been designed based on quantitative analysis results, which gives explicit evaluation criteria for determination of microstructure array performance. We will present the quantitative analysis results performed by COMSOL Multiphysics ...

Debris, micro particles produced by discharges, stay in the gap area during deep hole machining by micro EDM, cause short-circuits and abnormal discharges, finally make machining impossible. Although a deep hole can be processed by using the tool with grooves on the surface, the effect of the tool shape on the flow of working fluid and the behavior of debris are not clear yet. In this research, ...

Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal part we would be able to decrease the current density that would be dissipated to fetus and amniotic ...
