to teach english adequately, qualified teachers are needed. unfortunately, there are still teachers who are teaching english without an academic degree in tefl. it is necessary for teachers to have a major in english to have subject knowledge, but it is not sufficient. teachers need to have an understanding of the social, cultural, moral, ethical, and pedagogical issues of education and practic...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
پیش بینی ریسک سهام توسط روش garch(1,1) در این تحقیق فراریت (انحراف معیار استاندارد بازده) که رایج ترین معیار برای سنجش ریسک می باشد، برای بازده سهام (ناشی از تفاوت قیمت سهم در دو زمان متفاوت) توسط روش garch(1,1) یا generalized autoregressive conditionally heteroskedastic با پارامترهای p=1 و q=1 پیش بینی می شود.برای این کار داده های مربوط به قیمت سهام و به دو قسمت تقسیم می شوند: in-sample و out...

We report on the design, modeling, fabrication and testing of a new electrothermal actuator allowing for various modes of movement and exhibiting large enough forces to be usable in a micro-tribotester. The performance of the actuator has been simulated combiniig numerical and analytical calculations. Experiments have been performed in ambient conditions and vacuum. The theoretical results and ...
In this paper, we show how surface-micromachined buckled cantilevers can be used to construct out-of-plane structures. We include the relevant theory necessary to predict the height and angle of plates attached to buckled cantilevers, as well as the mechanical stresses involved in assembly. These platforms can be assembled to any angle between 0◦ and 90◦ with respect to the substrate by changin...
the major aim of this study was to investigate the relationship between social and cultural capital and efl students’ critical thinking skills. this study takes this relationship in to account to see if people with different sociocultural status are different regarding their critical thinking skills. to this end, 160 university students majoring in english language and literature, english trans...
Three-dimensional MEMS magnetometers with use of residual stresses in thin multilayers cantilevers are presented. Half-loop cantilevers based on Lorentz-force deflection convert magnetic flux in V ∆ changes, thanks to piezoresistive transducers mounted in Wheatstone bridge. Magnetic field in the order of 10 Gauss was measured with a sensitivity of 0.015 mV/Gauss. A Finite Element Model of the d...
