In order to characterize surfaces with respect to their sound reflecting properties, the absorption and the scattering or diffusion coefficient can currently be measured under standardized laboratory conditions. However it is questionable whether the data from measurements performed under such laboratory conditions can be used to accurately model the actual sound field in rooms. Additionally, i...

This article describes the behavior of CernoxTM zirconium oxynitride film temperature sensors from Lake Shore Cryotronics, Inc. in magnetic fields up to 32 T at temperatures between 2 and 286 K. Results from a number of sensors with different dimensionless temperature sensitivities and from different production batches are analyzed and compared with previous results on carbon-glass sensors that...

Distributed energy resources based on grid-following inverters are the dominant part of future modern power systems. To achieve a higher performance, reliability enhancements and cost reductions such most important demands. In this respect, sensors one elements which greatly determine inverters, minimizing number may both lower costs reliability. addition, sensor data prone to cyber-attacks, se...

Abstract An optimized sliding‐mode observer control algorithm for permanent magnet synchronous motor (PMSM) is proposed to solve the problems in conventional algorithms (e.g., system chattering and phase delay). The adopts a new piecewise function as switching reduce chattering. low pass filter substituted with complex coefficient delay caused by filter. Moreover, counter emf back obtained usin...
