High frequency signal injection is considered a parameter independent sensorless speed and position estimation technique which operates efficiently at low and zero speed. That is due to the saliency presence in the machine, which gives information about the rotor speed and position. Therefore the high frequency signal injected into the motor is modulated by the rotor speed and position informat...

Low-permeability sandstone reservoirs have been widely used as a gas storage medium worldwide. Compared with the high porosity and permeability of sandstone, low-permeability may present different mechanical (deformation, damage or failure) acoustic responses under cyclic loading-unloading processes caused by high-rate injection–production underground storage. In this paper, multistage triaxial...

With the advance of high speed laser technology, optical interaction with microwave circuits has become highly viable. Such interaction is advantageous as the fiber is low-loss, lightweight, and immune to electromagnetic interference. In this paper, interaction of direct-modulated and gain-switched optical links with active antenna phased array systems is demonstrated. In the direct-modulated o...

Modern vehicles rely on a fleet of electronic control units (ECUs) connected through controller area network (CAN) buses for critical vehicular control. With the expansion advanced connectivity features in automobiles and elevated risks internal system exposure, CAN bus is increasingly prone to intrusions injection attacks. As ordinary attacks disrupt typical timing properties data stream, rule...

We built a phased array system for high-power simultaneous wireless information and power transfer (SWIPT) using four 5.8-GHz injection-locked magnetrons. In the magnetron state, transmission efficiency was measured at different modulation rates. The fluctuation in not more than 0.5%. observed that dynamic beamforming does affect communication quality. Using system, SWIPT experiments revealed f...
