This paper is about discrete sensitivity analysis. A triangular bending element with constant moment and six degrees of freedom is used. The required derivatives for sensitivity analysis are calculated explicitly. These formulations, finite element method and sequential linear programming are utilized to find shape optimization of plate bending structures. The numerical examples, which show the...

Discrete Models of Spatial Variability (DMSV) have limitations for soil identification in traditional soil maps. New approaches, generally called digital soil mapping (DSM), using continuous methods (CMSV), try to predict soil classes or soil properties based on easily-available environmental variables. The objective of this study was to map the soil classes of the Borujen area, Chaharmahal-va-...

In an attempt to manage the risk of mismatch between the actual claims and the anticipated claim amounts in motor insurance pool, we introduce a few new concepts of motor loss ratelinked securities such as motor loss rate options and motor loss rate swaps. These hybrid derivatives can transfer the motor insurance loss rate risks to the capital markets. For the valuation of the motor loss rate-l...

We present an O(N log2 N) algorithm for the computation of the first N coefficients in the expansion of an analytic function in ultraspherical polynomials. We first represent expansion coefficients as an infinite linear combination of derivatives and then as an integral transform with a hypergeometric kernel along the boundary of a Bernstein ellipse. Following a transformation of the kernel, we...

در حالت کلی معادلات دیفرانسیل با مقادیر اولیه را نمی توان دیفرانسیل می توان جواب طیف وسیعی از مسائل کاربردی را مشخص نمود با روش های تئوری حل نمود، لذا با حل عددی معادلات یک حالت خاص از مسأله مقدار اولیه، مسأله ای به فرم: y^=f(x,y) , y(a)=?, y^ (a)=?^^ است که مشتق اول در آن ظاهر نمی شود. این معادلات طیف وسیعی از پدیده های اطراف ما را شامل می شود، مثلاً معادلاتی که دارای جواب نوسانی هستند از ...

The observations in many applications consist of counts of discrete events, such as photons hitting a detector, which cannot be effectively modeled using an additive bounded or Gaussian noise model, and instead require a Poisson noise model. As a result, accurate reconstruction of a spatially or temporally distributed phenomenon (f) from Poisson data (y) cannot be accomplished by minimizing a c...
