An image contrast enhancement algorithm based on discriminant analysis is presented in this paper. An automatic adaptive segmentation algorithm, based on discriminant analysis, is utilized to segment the gray-values of an image into several clusters. After the adaptive segmentation algorithm, different object components of the image are segmented into separate clusters, called object planes. Th...

The design of earthquake-resistant buildings starts with defining the maximum lateral earthquake forces or their resultant. The amount of these forces depends on various factors, including coefficient of system behavior which depends on overstrength and its ductility. In this study, a method is presented for designing an earthquake-resistant system in which the distribution of lateral forces is...

The hydro turbine dynamics have a considerable influence on the dynamic stability of power system. In the study of dynamic stability, the system is modeled by the linear differential equations (small  signal analysis). Small signal stability of power systems is needed in all conditions and only is dependent on the conditions of power system performance before commotion occurrence. This paper pr...

This short paper gives an introduction to the \emph{rcss} package. The R package \emph{rcss} provides users with a tool to approximate the value functions in the Bellman recursion using convex piecewise linear functions formed using operations on tangents. A pathwise method is then used to gauge the quality of the numerical results.

We propose an approximation scheme for two important but difficult single-product inventory systems, specifically, the lost-sales system and the perishable product system. The approach is based on quadratic approximations of cost-to-go functions within the framework of Approximate Dynamic Programming via Linear Programming. We propose heuristics and evaluate their performance against existing h...
