vations from each of p genes. In [1] it is assumed that i , j = arg max{|β̂ij |} can be computed in time O(1) (it is also assumed that the inner products for updating the β̂ values can be computed in time O(1), but this is actually possible by using the fact that 〈Yk T , Y ∗ i − ηβ̂ijYj〉 = 〈Yk T , Y ∗ I 〉 − ηβ̂ij〈Yk T , Yi〉). This makes some sense, as the algorithm is implemented in Matlab and buil...
It has been shown that the static spin susceptibility of the Hubbard model of correlations for a narrow band calculated in the CPA remains finite for any simple-band model and the carrier number, except possibly in the case of a precisely half filled band. We show that this statement is more general and should be true if the Hubbard model could be solved exactly within the alloy analogy approxi...
سینتیک تخریب حرارتی خانواده ای ازپلیمرهای گرما سخت (پلی آمیدها) با استفاده از تکنیک tga ، در سه سرعت گرمادهی (0c min-1 20 و15 ،5/7) در اتمسفر نیتروژن بررسی شده است. روش های isoconversional (model – free) )از قبیل روش های فلاین، وال و ازاوا (fwo)، کیسینجر، آکاهیرا و سانوز(kas) و تانگ (tang) (و model – fitting (روش کوتس و ردفرن ((cr)استفاده شده اند تا سه تایی سینتیکی یعنی انرژی فعالسازی، فاکتو...
در این پژوهش نانو ذرات هیبریدی نانو لوله کربنی- اکسید روی سنتز و شناسایی شده¬است و نتایج آنالیز دستگاهی tem, sem و ft-ir تشکیل نانو ذره هیبریدی را تایید می¬نماید. اثر هیبرید سازی نانو لوله کربنی با اکسید¬ روی سرعت تخریب حرارتی یک ترموست بر پایه dgeba مورد بررسی قرار گرفت. مطالعات مقایسه¬ای نشان داد که سرعت تخریب با هیبرید سازی نانو ذرات کاهش می¬یابد و از روش زیر تبعیت می¬کند. rpure dgeba > r m...
abstract: in the paper of black and scholes (1973) a closed form solution for the price of a european option is derived . as extension to the black and scholes model with constant volatility, option pricing model with time varying volatility have been suggested within the frame work of generalized autoregressive conditional heteroskedasticity (garch) . these processes can explain a number of em...
since esp received universal attention to smooth the path for academic studies and productions, a great deal of research and studies have been directed towards this area. swales’ (1990) model of ra introduction move analysis has served a pioneering role of guiding many relevant studies and has proven to be productive in terms of helpful guidelines that are the outcome of voluminous productions ...
The ability of 42 global climate models from the Coupled Model Intercomparison Project Phase 6 (CMIP6), consisting 20 low resolution (LR) and 22 medium (MR), are evaluated for their performance in simulating mean extreme precipitation over Indonesia. Compared to Climate Hazards Group InfraRed Precipitation with Station data (CHIRPS), model climatologies interannual variability investigated indi...

[1] In a future climate warmed by increased greenhouse gases, increases of precipitation intensity do not have a uniform spatial distribution. Here we analyze a multi-model AOGCM data set to examine processes that produce the geographic pattern of these precipitation intensity changes over land. In the tropics, general increases in water vapor associated with positive SST anomalies in the warme...
