uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
این پژوهش با هدف ارزیابی مکانیسم تحمل به تنش سرما در ارقام بهاره بر روی دو رقم کلزای بهاره مقاوم به سرما زرفام و حساس به سرما option 500 در قالب یک آزمایش فاکتوریل سه عاملی با طرح پایه کاملا تصادفی با 3 تکرار صورت گرفت. گیاهچه ها تا مرحله 4 برگی در ?c 16/22 (شب/ روز) رشد کردند، نیمی از گلدان ها در همین شرایط نگهداری شدند (تیمار شاهد) و نیم دیگر به اتاق سرما با ?c 3/10 به مدت 7 روز منتقل شدند (ت...
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...
چکیده کلزا (brassica napus l.)، از خانواده ی شب بو و جز دانه های روغنی است. دانه های روغنی بعد از غلات و حبوبات جایگاه سوم را در تأمین غذای بشر بر عهده دارند. گونه ی براسیکا رتبه ی سوم را در بین گونه های روغنی به خود اختصاص داده است. تنش های محیطی از قبیل شوری، خشکی و سرما نقش مهمی بر عملکرد و بقای محصولات دارد. تنش شوری یکی از مهمترین تنش های غیر زیستی است که اثر نامطلوبی بر کیفیت و کمیت محصو...
Multiple Choice tests are utilized widely in educational assessment because of their objectivity, ease of scoring, and reliability. This study aimed to compare IF and ID of MC vocabulary test items and attempted to find whether these indices are affected by the number of options. To this end, four 20 item stem equivalent vocabulary tests (3-, 4-, 5-, and 6-option MC) were administered to 194 (1...
different areas of modern financial tools and processes activities contain the matters like innovations in financial tools engineering and risk management. derivatives and especially stock exchange option is part of this innovation. among all numerical procedures in calculating the value of derivatives and the risk sensitivity parameters of option, binomial models are widely used. in this stud...
The nonperturbative aspects of string theory are explored for noncritical string in two distinct formulations, loop equations and matrix models. The effects corresponding to the D-brane in these formulations are especially investigated in detail. It is shown that matrix models can universally yield a definite value of the chemical potential for an instanton while loop equations cannot. This imp...
Background and purpose: In recent decades, several studies have been performed to assess the impact of answer switching on multiple choice questions final score. But still there is a general belief that changing the initial response could decrease the test scores. The aim of this study was to evaluate the impact of answer changing on final scores in paramedical students. Material and method...
