Piezoelectric optical scanner is developed for multi-coordinate control of optical laser beam. Such type of optomicro-mechanical systems can be used for accurate angular or linear deflection of optical elements in various optomechanical and optoelectronic systems. The operating principle of these devices is based on piezoelectric effect and on conversion of high-frequency multi-dimensional mech...

Abstract Developing a method to detect internal leakage in hydraulic cylinder, which is used for Electro‐Hydrostatic Actuators (EHA), important prevent serious malfunctions aircrafts. At present, the an EHA cannot be accurately detected only using operational data. This paper proposed convolutional neural networks (CNN) based cylinder according relationship between state parameters of and cylin...

Abstract Background Cylinder blasts can inflict multi-system life-threatening injuries to one or many persons simultaneously if they are nearby. The explosion in high-pressure equipment produces due its varied effects. Cases have been reported where the blast occurred balloon gas cylinder, oxyacetylene oxygen coffee machine, and compressor of a split air conditioner (AC). Most cases accidental....

In a multi-cylinder type liquid piston Stirling engine (MCLPSE), columns in U-shaped tubes play the role of solid pistons mechanical engine. Besides straightforward structure, advantages MCLPSE are relatively low operation temperature difference below 100 K and use harmless working fluids air water. This study presents mass spring model for MCLPSE, from which we determine geometrical parameters...
