We present new measurements conducted on a single-photon imager implemented in CMOS technology. The sensor was designed to sustain massive doses of Gamma irradiation, X-rays, and proton bombardment. The chip was also designed to operate continuously in large magnetic fields without measurable noise and distortion. The imager consists of an array of 32x32 photon counting pixels with a pitch of 3...

because of high strength to weight ratio, 6061 aluminum has many applications in different industries like automotive and aerospace industries and can help to reduction of fuel consumption. forming limit diagram (fld) is a useful method for sheet metal formability identification. whereas calculation of forming limit diagram by experimental tests is expensive and time consumption, in the present...

Models describing microscopic or mesoscopic phenomena in physics are inherently discrete, where the lattice spacing between fundamental components, such as in the case of atomic sites, is a fundamental physical parameter. The effect of spatial discreteness over front propagation phenomenon in an overdamped one-dimensional periodic lattice is studied. We show here that the study of front propaga...

A kinematic diagram of an electromechanical transmission a high-speed tracked vehicle with two traction electric motors, on-board gearboxes and ZK-type differential turning mechanism, which makes it possible to effectively distribute power flows between the sides during curvilinear motion, is proposed.

This paper includes modeling and simulation of 180 MW units of pumped storage power plant with Variable speed machines. In this method, voltage source inverters are used instead of traditional cyclo-converters. This paper aims to control the voltage source inverters and maintain DC voltage at a constant value. AC/ DC/ AC converter is used in system configuration structure in order to control an...

Unsupervised machine learning applied to the study of phase transitions is an ongoing and interesting research direction. The active contour model, also called snake was initially proposed for target extraction in two-dimensional images. In order obtain a physical diagram, model with artificial neural network unsupervised way by authors [Phys.Rev.Lett. 120, 176401(2018)]. It guesses boundary as...

Context. The Sun is a magnetic star whose magnetism and cyclic activity is linked to the existence of an internal dynamo. Aims. We aim to understand the establishment of the solar magnetic 22-yr cycle, its associated butterfly diagram and field parity selection through numerical simulations of the solar global dynamo. Inspired by recent observations and 3D simulations that both exhibit multicel...

This work focused on the influence of processing conditions on the mechanical properties of polypropylene (PP) and PP/mesoporous silica-hydroxyapatite (PP/MCM-41-HA) hybrid nanocomposites. The mechanical properties of PP were enhanced by adding MCM-41-HA nanoparticles. Neat PP and hybrid nanocomposites based on PP, containing maleic anhydride-grafted polypropylene (PP-g-MA) and MCM-41-HA, were ...

There are a number of high volume applications for DC motors that require precision control of the motor’s speed. Phase locked loop techniques are well suited to provide this control by phase locking the motor to a stable and accurate reference frequency. In this paper, the small signal characteristics, and several large signal effects, of these loops are considered. Models are given for the lo...

Low-speed and heavy-load gears generate a lot of heat during meshing transmission, which leads to thermal deformation the affects transmission performance gear system. It is great significance explore influence law temperature effects on nonlinear dynamics Based principle deformation, taking into account effect parameters, including time-varying stiffness, tooth side clearance as well comprehen...
