The objective of fringe pattern analysis is to extract modulated experimental information in an image. Among the techniques used in the demodulation process is the Regularized Phase Tracking. In this technique, a functional is proposed which is usually solved with classical minimization methods. This paper presents a minimization method for this technique using the fixed-point technique, which presents a normalized error like classical minimization methods, but with a notable reduction in processing time.

An application of variational calculus: the costs minimization. This document try to promote the use of the variational calculus in optimization problems that come out from the decisions taking in several social sciences; in this case we are going to show it in an ad hoc problem where it is necessary determine the rate of production of some goods, taking into account both, the production cost and the storage fee. First, the mathematical modelling and the optimization methods are given, just for continuous or discrete time models. Then, structure of the general problem to be resolved with calculus of variations is introduced together with a brief historic outline of this branch of mathematics, some of the forefathers and the problems they addressed. The formal deduction of the Euler Equation is presented. This equation will be used to resolve the application problem. At the end, the result obtained by Euler condition is compared against the production at constant rate, and the savings. [ABSTRACT FROM AUTHOR]

In this paper an algorithm for the numerical solution of nonlinear equations systems is presented. For this purpose the system of equations becomes a function of real value which will be minimized, in the global sense, in a given initial domain (a box in n) using analysis of intervals. The designed algorithm has the ability to determine the existence or not of solutions to the system of equations in a given box. The solutions of the system of equations, if they exist inside the given box, are expressed by means of enclosures by sub-boxes whose size is smaller than the established accuracy. There is not restriction about the relationship between the number of equations and the number of unknowns of the system. It is also carried out an analysis of the convergence of the algorithm, and the results of their application are shown for some test problems. [ABSTRACT FROM AUTHOR]

Evolution Strategies is a bio-inspired, robust, and efficient technique for solving optimization problems where the solution space is unrestricted. However, this assumption is unreal in many cases because the solution space is limited by complex boundaries in the form of linear and non-linear restrictions. In this paper, a modification of the original algorithm of Evolution Strategies for optimizing problems where the solution space is bounded using complex restrictions is proposed. The proposed method is based on the use of a penalization function which is zero inside of the feasible region and equal to the maximum value inside of the feasible region when an unfeasible point is considered. The proposed approach is proved using six benchmark problems. In all cases, our approach found an optimal point equal or lower than the values reported in the literature. [ABSTRACT FROM AUTHOR]

This article assesses the application of a mathematical method, Linear Programming, for providing supporting information in managerial decision making processes of small and medium-sized businesses (PYMES in Spanish). These productive entities are efficient stimulants in social development, but the technique of Linear Programming has not been utilized to its maximum potential by developers and advisors of the PYMES sector. This research, then, attempts to discover, in detail, the methodological peculiarities of this technique through the presentation of a model generated for one small productive business. The results will provide clear evidence that Linear Programming constitutes a powerful analytical instrument for members of the PYMES sector. [ABSTRACT FROM AUTHOR]

There is a different way to produce the goods our society requires or not, by the efficient use of natural resources without waste remains that threat biodiversity and human health, and generating added value from an adequate environmental management. This alternative way to make goods is done by the use of new techniques of waste management, like, for instance, minimization. For this objective, it is necessary to adopt organizational and operative measurements which allow a diminution of waste and remains from industries to feasible levels, under economical and technical terms. The benefits obtained are not only for environment, they also allow the increase of quality of the products saving resources and improving the enterprise's utilities. This represents a competitive advantage, due to the development of more environmentally amicable products, as a new marketing strategy. [ABSTRACT FROM AUTHOR]

In this paper it is presented a methodology for the minimization of residuals and industrial emissions, which is a guide for the environmental work developed in the Biotechnology Department of the Solar Energy Research Center. The paper presents the advantages of the preventive solutions for the industry. The techniques used for the pollution minimization in the industry, as well as an example of applications in the Caney factory in Santiago de Cuba are also presented. [ABSTRACT FROM AUTHOR]
