هدف از انجام این پروژه بررسی روشهای مختلف حل لایهء مرزی در جابجائی آزاد روی یک صفحهء تخت قائم با درجه حرارت ثابت و متغیر برای دو نوع جریان آرام و مغشوش است .در این پروژه از دو روش انتگرالی و local nonsimilarity لایه مرزی جابجایی آزاد جریان مغشوش روی صفحه ای با درجه حرارت متغیر مورد تحلیل قرار گرفته است .
In this paper, we introduce RF electron gun of Iranian Light Source Facility (ILSF) pre-injection system. Design, fabrication and low-power microwave tests results of the prototype RF electron gun have been described in detail. This paper also explains the tuning procedure of the prototype RF electron gun to the desired resonant frequency. The outcomes of this project brighten the path to the f...
after the soviet union dissolution, a chaotic period was begun in the russia. russia lost its glory and felt disgrace. the first group of elites came to power under yeltsin; they tried to re-define russia’s identity as a european country and build a foreign policy on this baseline. therefore russia tried to become closer with the west especially with the u.s. according to their view the sovie...
With recent advances in power-electronics, inverter-based microgrids are gaining great attention. Droop control is one of the main methods to share the real and reactive power among distributed energy resources (DERs) in an islanded microgrids. Due to different characteristics of microgrid feeders, reactive power sharing is not fully accurate and consequently, some DERs may face overload. To ad...

As an efficient alternative to fossil fuels, renewable energy sources have attained great attention due to their sustainable, cost-effective, and environmentally friendly characteristic. However, as a deficiency, renewable energy sources have low reliability because of their non-deterministic and stochastic generation pattern. The use of hybrid renewable generation systems along with the storag...
differential steering of in-wheel electric vehicle provides the functions of both active steering and power assisted steering with the coupling control of force and displacement transfer characteristic of system. a collaborative optimization model of the differential power-assisted steering system of in-wheel electric vehicle is built, with steering economy as the main system optimization goal,...
A significant number of operating nuclear power plants (NPP) is approaching the end initially estimated design life. Considering that are stable and competitive, it may be possible to extend lives 60 years (perhaps even longer). Before expending life time, ageing in NPPs must effectively managed ensure availability functions throughout plant service From safety perspective, this means controlli...
