بارش، رواناب و رسوب از مهمترین پارامترهای هیدرولوژیکی می باشند و از آنجایی که تخمین پارامترهایی مانند رواناب و رسوب در طراحی، ساخت و نگهداری سازه های هیدرولیکی بسیار حائز اهمیت می باشد، بررسی و شناخت صحیح مراحل ایجاد و انتقال آنها نیز لازم و ضروری به نظر میرسد. این تحقیق بر عدم توانایی روش های ساده ای مانند منحنی های سنجه متداول، برای تخمین صحیح و عدم کارایی آنها برای تفسیر دقیق تغییرات پارامتر...

Dynamic phase transition in diluted kinetic Ising model in two dimensions has been studied in presence of external time dependent oscillating magnetic field applying Glauber Monte Carlo spin flip dynamics. A dynamic phase transition from a dynamically ordered to dynamically disordered ferromagnet is identified studying dynamic order parameter against temperature for different concentrations of ...

— In electromagnetic applications, hysteresis phenomena in magnetic materials are responsible of considerable causes of losses especially in transformer modelling cases. In specific case, such as current sensor, the output signal can be modified because of this loss. The paper presents the implementation proceeding used for some hysteresis material models and how they are applied in a sensor st...

Medicine, University of Alabama at Birmingham, Birmingham, AL, USA Full list of author information is available at the end of the article Figure 1 Schematic diagram for calculating torsional hysteresis–the area within the systolic and diastolic arm of the normalized torsion volume (TV) curves (A), normalized TV curves for the two groups (B) and calculated torsional hysteresis (C). Torsion hyste...

In this research, M-type Mn-Zr doped Ba-ferrites powders with a general chemical composition of BaFe10.6(ZrxMn1-x)O19 ( x= 0, 0.2, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, 1) were synthesized and prepared by a solid state method, and were then mixed with anAraldite + hardner and processed into polymer matrix composite specimens. Phase analyses of synthesized samples wereperformed by an XRD technique and ...

Theoretical models are adapted to describe the hysteresis effects seen in the electrical characteristics of carbon nanotube field-effect transistors. The ballistic transport model describes the contributions of conduction energy sub-bands over carbon nanotube field-effect transistor drain current as a function of drain-source and gate-source voltages as well as other physical parameters of the ...
