r&d; is one of the most important and suitable strategies government’s policies for increasing of agricultural production and supply. in this study, in addition of economic evaluation of agricultural r&d; and determination of its rate of return, optimal iran’s agricultural r&d; expenditure is determined. so, in this article, ex-post and ex-ante evaluation by using of mathematical programming ap...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
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...
in this thesis, using concepts of wavelets theory some methods of the solving optimal control problems (ocps). governed by time-delay systems is investigated. this thesis contains two parts. first, the method of obtaining of the ocps in time delay systems by linear legendre multiwavelets is presented. the main advantage of the meth...
این پایان نامه به تشریح و تبیین نتایج مقاله ی زیر می پردازد: g. zeng, henselian valuations and orderings of a commutative ring, proc. amer. math. soc. 135(2007), 929- 938. هدف اصلی در مقاله فوق بررسی ارتباط بین ارزیاب های هنسلی و ترتیب ها(یا نیم ترتیب ها) روی یک حلقه می باشد. نتیجه اصلی این است که برای ارزیاب هنسلی v روی حلقه r شرایط زیر معادلند: ارزیاب v با هر نیم ترتیب روی r سازگار است؛...
there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
In this paper, we provide R-estimators of the location of a rotationally symmetric distribution on the unit sphere of R. In order to do so we first prove the local asymptotic normality property of a sequence of rotationally symmetric models; this is a non standard result due to the curved nature of the unit sphere. We then construct our estimators by adapting the Le Cam one-step methodology to ...
target tracking is the tracking of an object in an image sequence. target tracking in image sequence consists of two different parts: 1- moving target detection 2- tracking of moving target. in some of the tracking algorithms these two parts are combined as a single algorithm. the main goal in this thesis is to provide a new framework for effective tracking of different kinds of moving target...
