the full adders (fas) constitute the essential elements of digital systems, in a sense that they affect the circuit parameters of such systems. with respect to the mosfet restrictions, its replacement by new devices and technologies is inevitable. qca is one of the accomplishments in nanotechnology nominated as the candidate for mosfet replacement. in this article 4 new layouts are presented fo...
operational variables of a mineral processing circuit are subjected to different variations. steady-statesimulation of processes provides an estimate of their ideal stable performance whereas their dynamicsimulation predicts the effects of the variations on the processes or their subsequent processes. in thispaper, a dynamic simulator containing some of the major equipment of mineral processing...
a commercial ti-nanoxide was deposited on in-doped sno2 (ito) polymer substrates by tape casting technique with different thicknesses (7, 14 and 36μm) to be used as photoelectrode in flexible dye-sensitized solar cells (dsscs). ruthenium dye was adsorbed on each tio2 film for 24 h. the resulting photoelectrodes were used to form flexible dsscs in combination with elec...
The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...
The purpose of this paper is to introduce a different type of converter circuit used to drive switched reluctance motors. It continues with detailed discussion on the resonant converter armed at minimizing or eliminating the transistors switching losses. Finally the drive has been tested on a disc-type reluctance motor for the perfomance and functionality.
طراحی به روش آسنکرون به لحاظ پیچیدگی روند طراحی و کمبود ابزرهای پشتیبانی طراحی خودکار ، علیرغم مزیت-های عمده ای که دارد تنها به طور محدودی مورد استفاده قرار گرفته است . در طراحی مدارات سنکرون پروسه طراحی و ابزارهای تجاری cad مانند : سنتز کننده ها، آنالیزگرها، ابزار تایید صحت عملکرد مدار؛ پیشرفت بسزایی در سطوح مختلف پیدا کرده اند. از بررسی مدار در سطح بالا گرفته تا طراحی فیزیکی. ولی ابزارهای cad...

iran is a rather wide country, and, as a rule, the chrage per one call in s. t .d . (subscriber trunk dialing ) is required more compared with a local call , so, just after the opening of the std service widely in national telephone network, unconcerned use of the s. t. d. service has been caused on an incon- ceivable increase in telephone charge of th subscriber. this is a common problem for a...
Background: Different training regimes cause different physiological changes and adaptations. The aim of the present study was to investigate the effects of a four-week endurance and circuit resistance training on serum superoxide dismutase (SOD) and Heat shock protein (Hsp70) levels in inactive college students. Methods: Twenty-four inactive males (Age: 22.67±4.3 yrs, Weight: 69.95±14.8 kg...
