in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
although knowing the time of the occurrence of the earthquakes is vital and helpful, unfortunately it is still unpredictable. by the way there is an urgent need to find a method to foresee this catastrophic event. there are a lot of methods for forecasting the time of earthquake occurrence. another method for predicting that is to know probability density function of time interval between earth...

Abstract: In this paper, we fit a function on probability density curve representing an information stream using artificial neural network . This methodology result is a specific function which represent a memorize able probability density curve . we then use the resulting function for information compression by Huffman algorithm . the difference between the proposed me then with the general me...

In this paper, first, we investigate probability density function and the failure rate function of some families of exponential distributions. Then we present their features such as expectation, variance, moments and maximum likelihood estimation and we identify the most flexible distributions according to the figure of probability density function and the failure rate function and f...
در این گزارش با استفاده از شبکه بندی دینامیکی و کد نویسی udf و شبیه سازی احتراقی غیر پیش مخلوط، احتراق داخلی در یک موتور موشک هیبرید شبیه سازی گردید. در پدیده گرماکافت سوخت، با استناد بر تحقیقات انجام گرفته، گاز بوتادین c4h6 جایگزین سوخت اصلی htpb گردید. همچنین در شبیه سازی پدیده گرماکافت سوخت از متد عبارتهای مولد (source terms) جرمی و اندازه حرکت استفاده شد. جهت تولید شبکه های دینامیکی از متد ...
