Improving the operational reliability of nuclear power plants, combined heat and plants (CHP), as well oil gas pipelines is a priority task in development variable-speed drive for lock valves used at these facilities. This paper analyzes technical requirements such devices: motor has been selected, its electrical equilibrium moment equations have obtained; recommendations selection kinematic sc...

The CCC-r chart is developed based on cumulative count of a conforming (CCC) control chart that considers the cumulative number of items inspected until observing r nonconforming ones. Typically, the samples obtained from the process are analyzed through 100% inspection to exploit the CCC-r chart. However, considering the inspection cost and time would limit its implementation. In this paper, w...

Artificial Muscles A flexible electric artificial muscle capable of self-sensing and rapidly adjusting the stiffness along stretching direction is developed referencing biological smooth contraction. The integrated function enables fast response to stimuli simplifies control actuation-sensing system, which opens up new possibilities for advancing soft robotics wearable medical rehabilitation de...

This paper presents a novel three-dimensional active frequency selective surfaces loading a varactor diode to achieve electrically controllable, by loading different values of paranoid voltage to control the variable capacitance diode. Simulation results show that the structure has excellent resonant characteristics in the range of 3.34GHz-1.59GHz, and has certain sensitivity for the change of ...
