The program TRANALYZE generates a gate-level representation of an MOS transistor circuit. The resulting model contains only four-valued unit and zero delay logic primitives, suitable for evaluation by conventional gate-level simulators and hardware simulation accelerators. TRANALYZE has the same generality and accuracy as switch-level simulation, generating models for a wide range of technologi...
This paper represents a comparative study of isolated resonant topologies for photovoltaic application such as half bridge, full bridge and push pull topology. The performance of these topologies is analyzed with the help of Pulse Width Modulation (PWM) technique. The stressful behavior of the switches is reduced by soft switching technique. So, the primary side switches utilize zero voltage sw...
در این پروژه تلاش می شود کلیدزنی سریع حالت های کوانتومی را با استفاده از خصوصیات اسپین بررسی نمائیم. اندرکنش اسپین و میدان الکتریکی برای تغییر واهلش مورد بررسی قرار می گیرد. د این بررسی تلاش خواهد شد با استفاده از ماهیت کوانتومی اسپین و مدیریت اسپین کلیدزنی حالت کوانتومی با کمترین انرژی و کمترین سرعت عملی شود. در این تحلیل معادلات دینامیکی اسپین تهیه شده و با استفاده از اندرکنش با نور پارامترها...
in this research, the structural behavior of timber and concrete sleepers in a standard railway turnout is evaluated, in the case of raising speed. in approaching this evaluation, current practices in the structural analysis of sleepers are surveyed and then, the sensitivity analysis with abaqus software is made based on selected criteria (bending and shear stresses as well as contact pressure)...
The reversal of flagellar motion (switching) results from the interaction between a switch complex of the flagellar rotor and a torque-generating stationary unit, or stator (motor unit). To explain the steeply cooperative ligand-induced switching, present models propose allosteric interactions between subunits of the rotor, but do not address the possibility of a reaction that stimulates a bidi...
Direct current circuit breakers (DCCBs) have become a large research topic and are considered one of the critical components for future DC grids. Proposed DCCB concepts may be grouped into hybrid DCCBs active resonant DCCBs. In this work, enhanced (EAR) family is introduced. EAR combine elements The consists unidirectional six bidirectional concepts. All feature proactive commutation. main char...
OBJECTIVE To define the lowest age at which the bidirectional superior cavopulmonary anastomosis can safely be used in infants with complex congenital heart defects. DESIGN A retrospective analysis of clinical, echocardiographic, haemodynamic, and angiographic data in four consecutive patients undergoing bidirectional superior cavopulmonary anastomosis below the age of 2 months. PATIENTS Be...
We propose a real-time measurement system that prevents overlapping reflection signals in fiber Bragg gratings (FBGs). The combines wavelength-swept laser using Fourier domain mode-locking (FDML) and buffer stage with three optical paths to obtain high-speed rate of 304.2 kHz. Systems lasers are affected by the propagation time (delay) fiber. delay causes problems such as inaccurate measurement...
This article proposes a novel device designated as an intelligent electronic fuse (iFuse) intended to be connected in series with any current-bidirectional voltage-unidirectional active switch present power converter. The iFuse duty is selectively isolate its series-associated from the rest of converter circuit immediately after detecting that this has failed short circuit. Nonetheless, it main...
