Machine studies have been conducted in the SPS to better characterise the transverse instabilities observed on the LHC beam by the beam induced electron cloud. Most of the observations have been performed at injection energy. Different beam configurations have been considered as a function of their availability from the injectors. The results of these observations (bunch centroid motion, head-t...

“X-Ray Vision”: Taking a Hard Look at Fuel Sprays and Combustion Argonne researchers are collaborating on a close-up study of diesel spray patterns and soot formation using the Advanced Photon Source here at the Laboratory. The APS makes it possible for scientists to examine these phenomena closer than ever before. The knowledge gained could lead to better-performing, loweremission injectors fo...

The numerical solution of very large 3D electromagnetic field problems are challenging for various applications in the industry. In this paper, we propose a nonoverlapping domain decomposition approach for solving the 3D Maxwell equations on MIMD computers, based on a mixed variational formulation. It is especially well adapted for the solution of the Vlasov-Maxwell equations, widely used to si...

In many research centers all over the world nowadays works are being carried out aimed at compiling method for diagnosis machines technical condition. Special meaning have non-invasive methods including methods using vibroacoustic phenomena. In this article is proposed using DWT analysis and energy or entropy, which are a base for diagnostic system of fuel injectors damage in car combustion eng...
