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 purpose of this study is to evaluate coal and byproducts (coal waste, ash, acid mine drainage) in Indiana as potential sources rare earth elements (REE). On a whole-rock basis, most samples have REE content below 100 ppm, only some the Brazil Staunton Formations (Lower Upper Block Viking B coals) reach ppm. Because concentrations vary between locations within individual beds, correlations c...
Background: Dermatomyositis is a multi organ autoimmune disease wich commonly complicated with interstitial lung disease. Chest high-resolution computed tomography (HRCT) still considered the diagnostic gold standard for and quantification, however he increasing use of ultrasound may play an important role in future. Objectives: The aim our study was to determine value detection progression pul...

Codon usage patterns in the slime mould Dictyostelium discoideum have been re-examined (a total of 58 genes have been analysed). Considering the extreme A + T-richness of this genome (G + C = 22%), there is a surprising degree of codon usage variation among genes. For example, G + C content at silent sites varies from less than 10% to greater than 30%. It was previously suggested [Warrick, H.M....
due to lack of knowledge management system in the organization of technical and vocational university of iran (tvuni) and losing good employees because of retirement and substitution causes huge amount of costs to replace the similar expertise. there is no any suitable system in the tvuni to store, to document, and to distribute knowledge. based on the university’s features such as it has diffe...
یکی از مهمترین روشهای تحلیل سازه ها در مهندسی مکانیک استفاده از مدل المان محدود است که اعتبار سنجی مدل مذکور، اهمیت بسزایی دارد. بدین منظور معمولا سازه مورد نظر را بصورت تجربی تحت تست آنالیز مودال قرار می دهند که مسلما فرکانس ها و شکل مود استخراجی با نظایر استخراج شده در مدل المان محدود اختلاف دارد. برای به حد اقل رساندن این اختلاف از روش های موسوم به مدل بروز رسا نی شده ) ( model updatingاستفا...
