In conversation, speakers become more like each other in various dimensions. This phenomenon, commonly called entrainment, coordination, or alignment, is widely believed to be crucial to the success and naturalness of human interactions. We investigate entrainment in four acoustic and prosodic dimensions. We explore whether speakers coordinate with each other in these dimensions over the conver...
building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
This paper aims at to develop floating gate MOSFET (FGMOS) based low voltage, voltage-mode and current-mode circuits operating at ± 0.75 V supply voltages. The utility of FGMOS for low voltage applications lies in its threshold voltage tunability. FGMOS based low voltage current mirror and its subsequent use in the development of second-generation current conveyor is presented which in turn has...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
in this paper, a low voltage and low power (lv/lp) operational transconductance amplifier (ota) using fgmos (floating-gate mos) transistor is proposed. the relative tuning range of 50 is achieved in this ota while only consumes 40 µw with 1.0 v supply voltage in tsmc 0.18 µm cmos technology. the simulation results of the proposed ota show an open loop gain of 30.2 db and a unity gain frequency ...
In this paper, a bidirectional DC-DC converter with high power density for energy storage application is proposed. The presented converter provides power transfer in both directions only with adjusting phase shift angle. Zero voltage switching (ZVS) in both turn on and turn off moments of all switches is the major capability of the converter that makes it suitable for high power applications. Z...
this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...
propose: standard electroporation and electrochemotherapy caused the endothe- lial cell permeability and reduction in tumor blood flow. the effects of low voltage and high frequency electroporation on the endothelial cells permeability and viability were expected. therefore, the propose of present study was to evaluate the effect of electroporation with bleomycin or alone on viability and perme...
InGaP/InGaAs doped-channel direct-coupled field-effect transistor logic (DCFL) with relatively low supple voltage is demonstrated by two-dimensional analysis. In the integrated enhancement/depletion-mode transistors, subband and two-dimensional electron gas (2DEG) are formed in the InGaAs strain channels, which substantially increase the channel concentration and decrease the drain-to-source sa...
In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...
