In this paper a novel approach based on Asymptotic Iteration Method (AIM) is presented to solve analytically the light propagation through one-dimensional inhomogeneous slab waveguide. Practically implemented optical slab waveguides based on traditional techniques are usually inhomogeneous and numerical methods are used to obtain guided wave characteristics. In this work, we develop analytical ...

in the process of modernization, traditional dress is usually the first issue which changes in traditional societies. undoubtedly, western societies, benefiting from their worldwide cultural industry, are leading the globe to a great uniformity which peoples’ dress is one of its apparent out comes. today, in our society emergence of west culture through the process of globalization on one hand,...

Care in the preparation and preservation of reagents, together with certain modifications in apparatus and technique, have eliminated the difficulties from plasma ammonia analysis. Ammonia contamination from the laboratory atmosphere has not proved an especial hazard, and no major setback has been encountered in the analysis of several thousand specimens over the last few years. The method has ...

The importance of studying glycogen that has been prepared without the use of strong caustic alkali has been pointed out in previous papers’s2 In one of them (Petree and Alsberg), amethod of preparation based on the removal of protein with picric acid was described. In the present paper, an improved method with trichloroacet,ic acid is presented, and rabbit liver glycogen prepared by it is desc...

Spam filtering is a text categorization task that shows especial features that make it interesting and difficult. First, the task has been performed traditionally using heuristics from the domain. Second, a cost model is required to avoid misclassification of legitimate messages. We present a comparative evaluation of several machine learning algorithms applied to spam filtering, considering th...

In this work a new and promising algorithm based in the minimization of especial functional that depends on two regularization parameters is considered for identification of the heat conduction coefficient in the parabolic equation. This algorithm uses the adjoint and sensibility equations. One of the regularization parameters is associated with the heat-coefficient (as in conventional Tikhonov...

In this paper we propose some generic extensions to the general selection concept of a Genetic Algorithm (GA). These bionically inspired interrelated further developments aim to make the algorithm more open for scalability on the one hand, and to stabilize the performance of weaker crossover operators on the other hand without necessitating the development of new coding standards and operators ...
