The hysteresis motor is so named because it is producing mechanical torque utilizing the phenomenon of hysteresis. The rotor of a hysteresis motor is a cylindrical tube of high hysteresis loss permanent magnet material without windings or slots. This paper presents the design of a hysteresis permanent magnet motor using the finite element method. The rotor of the machine consists of 36% Cobalt ...

Abstract Due to high bearing capacity and excellent seismic performance, the section steel reinforced concrete-filled rectangular tube has been widely applied in engineering. The application of stainless for outer can improve durability performance members. In this study, ABAQUS software was used perform nonlinear analysis on tubular columns, numerical model validated against experimental data....

Establishment of rating curves are often required by the hydrologists for flow estimates in the streams, rivers etc. Measurement of discharge in a river is a time-consuming, expensive, and difficult process and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods.

The present article seek to investigate the function of elliptical steel damper function in steel frames seismic resisting. The elliptical damper is a kind of earthquake energy dissipater in structure which acts based on the steel yielding feature. Thus, this damper in frame lateral displacement mechanism is expected to have a satisfying hysteretic behavior in terms of energy absorption is on a...

The operation of the TiN/HfO 2 /Pt bipolar memristor has been simulated by finite elements method using Maxwell steady state equations as a mathematical basis. simulation provided knowledge effect conductive filament thickness on shape I-V curve. considered highly Hf ion enriched HfO x phase ( < 2) whose structure is similar to Magneli phase. In this work mechanism developed describing forma...

In this research, softening and ratcheting behaviors of Ck20 alloy steel cylindrical shells were studied under displacement-control and force-control cyclic axial loading and the behavior of hysteresis curves of specimens was also investigated. Experimental tests were performed by a servo-hydraulic INSTRON 8802 machine. The mechanical properties of specimens were determined according to ASTM E8...

Adding steel braces to reinforced concrete frames is a common way for seismic rehabilitation of these structures. Due to ease of installation and the possibility of creating openings in the braced bays, this method of rehabilitation has been more preferred than using shear walls. In this paper, three experimental specimens including a reinforced concrete frame, a reinforced concrete frame with ...

We propose the encoding of memristive quantum dynamics on a digital computer. Using set auxiliary qubits, we simulate an effective non-Markovian environment inspired by collisional model, reproducing features between expectation values different operators in single qubit. numerically test our proposal IBM simulator with 32 obtaining pinched hysteresis curve that characterizes memristor model. F...

Hysteresis current control method is vastly used in PWM inverters because of simplicity in performance, fast control response and good ability in limiting peak current. However, switching frequency in hysteresis current control method with fixed bandwidth has large variation during a cycle and therefore causes non-optimal current ripple generation in output current. One of basic problems in imp...
