The paper considers methods of parametric optimization a dynamical system, which is described by system differential equations. gradient the functional in form Boltz found, basis such as descent. Another method based on application sensitivity function.
Durum wheat (Triticum turgidum L.), like most other crops, is affected by various stresses. Therefore, cultivars that, in addition to the ability to produce higher yields, can maintain their yield potential in different years and locations are considered superior cultivars. In order to obtain high-yielding and stable genotypes of durum wheat, 16 lines with two control cultivars Dehdasht and Sey...
evaluation of river discharges trends is very important for water resources management and design of irrigation and drainage networks. in this research, annual, seasonal and monthly trends of maroon river discharge were evaluated using the mann-kendall and senâs slope estimator non-parametric tests and the regression analysis parametric test. for this purpose, river discharge data from five h...
Synthetic Aperture Radar (SAR) is the only way to evaluate deformation of the Earth’s surface from space on the order of centimeters and millimeters due to its coherent nature and short wavelengths. Hence, by this means the long term risk monitoring and security are performed as precisely as possible. Traditional SAR imaging delivers a projection of the 3-D object to the two dimensional (2-D) a...
داده های فضایی در بررسی های علوم محیطی مانند هواشناسی، محیط زیست، زمین شناسی و اقیانوس شناسی در طول زمان نیز به یکدیگر وابسته ان. تحلیل این گونه داده ها مستلزم تعیین ساختار همبستگی فضایی-زمانی آن ها از طریق کواریانس است. در دو دهه اخیر بررسی های زیادی برای مدل بندی و تحلیل چنین داده هایی صورت گرفته است. در این پایان نامه روش رگرسیون چندک بیز برای تحلیل داده های فضایی-زمانی ارائه شده است .
