abstract in a protocol analysis of second language writing from 20 adult english as a foreign language (efl) iranian students, this research observed how language-switching (l-s), i.e., first language use in l2 writing, was affected by l2 proficiency. switching interactively between first (l1) and second (l2) languages has been recognized as one of the salient characteristics of l2 writing....
This paper presents a novel RF MEMS (Micro Electromechanical System) fixed-fixed switch for very fast switching. Using the obtained equations, the switching time depends on the stiffness and effective mass of the switch beam so that the switching time will be decreased by higher stiffness (spring constant) and lower effective mass. In new design, the suspension bridge is a three-layer beam so t...
In this paper, for the first time, the effect of the substrate doping of 22nm double-insulating UTBB silicon-on-insulator device on the switching performance and turn-on delay of the transistor is investigated. In UTBB devices, the substrate voltage is varied from positive to zero then negative voltages to trade-off transistor speed against the leakage current. Various circuit design procedures...
Transformerless topologies are widely preferred to use in the grid connected photovoltaic (PV) generation system due to higher efficiency, lower cost and lower weight in comparison with other topologies employing transformer. In this paper, switching losses is minimized by incorporating Zero Voltage Switching (ZVS) in a full-bridge topology, at switch turn-on and an adaptive Variable dead-time ...
T he main purpose of this article is to analyze exchange rate behavior based on monetary fundamentals in the context of Iranian economy over the period 1990:2 to 2014:3. To do so, two monetary exchange rate models is investigated, the first by regarding interest rate differential as a monetary variable, and the second one regardless of interest rate differential as a monetary variabl...
Background and Objective: Breathing through the nose and mouth is one of the controversial issues during exercise. The present study was scheduled to investigate a quantitative approach to habitual versus the obligatory switching point from nasal to oronasal breathing during exercise as well as coincidence of soft palate movement as the main aims of this study, that has not been studied previou...
the large amount of computation necessary for obtaining time optimal solution for moving a manipulator on specified path has made it impossible to introduce an on line time optimal control algorithm. most of this computational burden is due to calculation of switching points. in this paper a learning algorithm is proposed for finding the switching points. the method, which can be used for both ...
This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...
In this article, a new approach is proposed to design robust switching gain-scheduled dynamic output feedback control for switched uncertain continuous-time linear parameter varying (LPV) systems. The proposed robust switching gain-scheduled controllers are robustly designed so that the stability and H2-gain performance of the switched closed-loop uncertain LPV system can be guaranteed even und...
