the purpose of this study was to investigate the relationship between teachers’ class management practices with students’ self- regulated learning and academic self-efficacy. in this study relating to the management class, three dimensions, (training management, people management and behavior management) and three style (interventionist, interactionist and non-interventionist) was considered. r...
Meson is composed of one quark and one antiquark moving under the effect of confinement, oscillating and color potentials. Since quarks are particles with spin , there is a spin-spin interaction potential. Also we have isospins for u and d quarks and we can consider related potentials on isospin-isospin and spin-isospin effects. By comparing the given meson spectrum with the amount calculated...
The aim of the present work is to study the evolution of organizational knowledge within Academic Spin-off (ASO) firms throughout their life cycle. The exploitation of tacit and indivisible new knowledge developed in the context of academic institutions entails agency problems of different nature; one way to address such challenges is the creation of new business firms by the inventors. At the ...
این پایان نامه شامل چهر فصل می باشد که در فصل اول به بیان تعاریف و مفاهیمی خواهیم پرداخت که در طول این پژوهش مورد نیاز است.در فصل دوم به بررسی خمینه هایی با ساختار (spin(7 خوهیم پرداخت.در فصل سوم به بررسی تجزیه فضای فرم ها خواهیم پرداخت، و در فصل چهارم با استفاده از مشتق گیری معادلات، شار عمومی روی ساختار (spin(7 را بدست خواهیم آورد.
We consider RVB state as a variational estimate for the ground state of Heisenberg antiferromagnet in square lattice. We present numerical calculation of energy, spin-spin correlation function and spin excitation spectrum. We show, that the quantum flactuations reduce of magnetization respect to Neel order. Our results are in good agreement with other methods such as spin-wave calculation a...
ما در این پایان نامه مفهوم ضرب خارجی روی $ mathbb{r}^{4} $ را تعریف خواهیم نمود و به کمک این ضرب یک ضرب شرکت پذیر روی $ mathbb{r}^{5} $ تعریف می نماییم که $ mathbb{r}^{5} $ با جمع معمولی و ضرب اسکالر و این ضرب شرکت پذیر یک جبر شرکت پذیر خواهد بود و با استفاده از این جبر نمایشی از گروه های لی کواترنیون ها و $ su(2) $ را بدست می آوریم. همچنین ما روی فضای $ mathbb{r}^{6} $ یک ضرب خارجی تعریف می ...

The prospect of building spintronic devices in which electron spins store and transport information has attracted strong attention in recent years. Here we present some of our representative theoretical results on three fundamental aspects of spintronics: spin coherence, spin entanglement, and spin transport. In particular, we discuss our detailed quantitative theory for spin relaxation and coh...
