growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
credit enhancements are methods that are used in structured finance for promoting the credit quality of financial instruments. one of the most important mechanisms for improving the credit quality is tranching financial instruments. this mechanism is mentioned as a structural and internal credit enhancement. tranching decreases financing costs and improves the quality of financial instruments. ...
هدف از انجام تحقیق .بر اساس یافته ها تاکنون میزان تاثیراین تکنیکها در مقایسه با سایر روشها براساس اطلاعات آماری و به صورت عددو رقم بررسی و نمایش داده نشده اند و به همین دلیل این رویکرد نتوانسته توجه اساتید و مربیان آموزش زبان را در کشورمان به خود جلب کند. از اینرودر این پژوهش بر آن شدیم تا میزان تاثیر تکنیکهای معرفی شده در این رویکرد را با انجام یک تحقیق آزمایشی بر روی سه گروه از دانشجویان برر...
In the visual cortex, feedback projections are conjectured to be crucial in figure-ground segregation. However, the precise function of feedback herein is unclear. Here we tested a hypothetical model of reentrant feedback. We used a previous developed 2-layered feedforward spiking network that is able to segregate figure from ground and included feedback connections. Our computer model data sho...
A high throughput method was designed to produce hyperpolarized gases by combining low-temperature dynamic nuclear polarization with a sublimation procedure. It is illustrated by applications to 129Xe nuclear magnetic resonance in xenon gas, leading to a signal enhancement of 3 to 4 orders of magnitude compared to the room-temperature thermal equilibrium signal at 7.05 T.
Repeated observations inhibit the coherent evolution of quantum states through the quantum Zeno effect. In multi-qubit systems this effect provides opportunities to control complex quantum states. Here, we experimentally demonstrate that repeatedly projecting joint observables of multiple spins creates quantum Zeno subspaces and simultaneously suppresses the dephasing caused by a quasi-static e...
the present study investigated comparatively the impact of two types of input enhancement (i.e. textual vs. compound enhancement) on developing grammar ability in iranian efl setting. sixty-five female secondary high school students were selected as a homogenous sample out of about a 100-member population based on nelson language proficiency test. then, their grammar ability was measured based ...
