Based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. However, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. To resolve this problem, hybridization of the fuel cell and energy storage device...
تحقیقات مختلف اثبات نموده اند که رشد و محتوای بیوشیمیایی روتیفرها می تواند تحت تاثیر نوع غذا و غلظت مواد غذایی تغییر نماید. ریز جلبک ها به عنوان یکی از منابع غذایی مهم برای کشت روتیفرها به ویژه از لحاظ شاخص های نظیر رشد، بقا، میزان پروتئین، چربی و اسیدهای چرب، ضروری می باشند. لذا تحقیق حاضر جهت مقایسه جلبک خشک (کلرلای پودری) و جلبک های تازه (ایزوکرایسیس گالبانا و نانوکلروپسیس آکولاتا) بر رشد، ت...
Deep learning method is used to predict the future value of load demand. Based on obtained results, a new model based on the forward-backward load shifting and unnecessary load shedding is presented. As well, to increase energy efficiency, excess renewable energy has been used to produce green hydrogen. For this purpose, GAMS optimization software has been used for optimal operation of the micr...
Measurement of the values of forces in tractor arms is of great importance due to draft of agricultural equipment. These values can be used for testing and evaluation of the agricultural machinery, selection of suitable tractor, etc. The tools which are used for measurement of the forces are called dynamometer. The main objective of the present study was to design and evaluate a load cell for i...

In the near future the use of distributed generation systems will play a big role in the production ofelectrical energy. One of the most common types of DG technologies , fuel cells , which can be connectedto the national grid by power electronic converters or work alone Studies the dynamic behavior andstability of the power grid is of crucial importance. These studies need to know the exact mo...
For measuring draft force and drawbar power requirements for mounted implements, precise instruments such as three-point hitch dynamometers and tractor speed measurement devices are needed. In this research, a frame-type three-point hitch dynamometer was built and evaluated. Forces applied to dynamometer are measured by three separate load cells located on a frame which can be attached to tract...
