An electro-optical measurement system for the DC characterization of visible detectors for CMOS compatible vision chips is presented which can help designers to characterize these detectors. The measurement system has been designed to be versatile, fast and easily expandable and used. Two different set-up's for the measurement of the spectral response and the optical dynamic range of the detect...
This article deals with an original haptic teleoperation and human–robot interaction (HRI) for microrobotic tasks involving optics more generally light information. It aims to demonstrate the proof of concept using information in component alignment submicrometer accuracy. The case study focuses on a laser optical fiber active surface photodiode system pantograph. Since error <inline-formula xm...
this thesis is about the effect of self-confidence and educational motivation on oral translation quality.
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
this study sought to examine the effect of cooperative game on iranian students achievements in english alphabet learning. cooperative games are games, in which players or teams work together towards a common goal without defeating someone. the methodology used in this study was experimental. the population of the study was 60 female students from the grade one in secondary school in tabriz, ir...
Electrooptical devices and optical communications need compounds with second-order nonlinear (NLO) properties as construction blocks. Typically, to show a large quadratic hyperpolarizability, compound should be asymmetric, characterized by variation between the dipole moments in excited ground states, have low energy electronic transitions. For example, hyperpolarizability can reached when an e...
تاثیر آموزش تفکر انتقادی به شیوه مباحثه بر روی مهارت درک متن یادگیرندگان انگلیسی به عنوان زبان خارجی
the purpose of the present study was to investigate the effect of instruction through debate on male and female efl learners’ reading comprehension, to examine the differences between the performance of male and female participants on the five dimensions of cctst including analysis, evaluation, inference, deductive reasoning, and inductive reasoning, and to examine the differences between male ...
a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
