The purpose of this study is to investigate comparative advantages of corn in comparison with other competitor crops. To do so, Linear Programming, to 2004-2005 data related to classic index (DRC) in Kermanshah province was applied. Results showed that corn has comparative advantages in all regions of Kermanshah province while in optimal cultivation pattern of 37.5 percentages of regions in exi...

To improve recognition results, decisions of multiple classifiers can be combined. We study the performance of combination methods that are variations of the majority vote. A Bayesian formulation and a weighted majority vote (with weights obtained through a genetic algorithm) are implemented, and the combined performances of 7 classifiers on a large set of handwritten numerals are analyzed.

Parallel pattern matching on a mesh-connected array of processors is considered. The problem is to nd all occurrences of a pattern in a text. The input text is a string of n symbols placed in a p n p n mesh, each processor storing one symbol. The pattern is stored similarly in a contiguous portion of the mesh. An algorithm solving the problem in time O(p n) is presented. It applies a novel tech...

The purpose of the research which led to this paper is to develop an analytical procedure for the design of the spectral channels for multispectral remote sensor systems. An optimum design based on the criterion of minimum meansquare representation error using the KarhunenLoeve expansion was developed to represent the spectral response functions from a stratum. From the overall pattern recognit...

Introduction: The problem of compressed pattern matching deals with ways to find a pattern within a compressed file, without decompressing it first. The techniques for solving this problem fall into two major categories – creating a unique compression scheme that enables efficient pattern matching; or using some known compression scheme and develop algorithms to search the files it produces. In...

Determination of optimal cropping pattern is essential for arid and semiarid regions. Lorestan province is located in the west part of Iran with mean annual precipitation from 50 to 1000 mm and in most parts of this province water resources for agriculture are deficit. Khoramabad region with semi-arid climate is located in Lorestan province with mean annual rainfall of 373 mm. The purpose of th...
