Abstract

The present work includes the preparation of ne'uv 2H-l-benzopyran-2- one derivatives. The ethyl (4-methyl-2-oxo-2H-l-benzopyrane-7-oxy) acetate (2) has been synthesized and then converted into the acid hydrazide derivative (3) which upon its reaction with aldehydes and ketones yielded the corresponding Schiff bases (4-9). Oxadiazole and thiadiazole derivatives (10,12) have been also prepared by the cyclization reaction ofthe acid hydrazide (3) under ditferent conditions, Whilst potassium dithio carbazate (11) prepared from stirring hydride (3) with CS2-KOH at room temperture. The synthesized compounds have been tested for their antibacterial activity.

Abstract

Artificial neural netrvorks have been developed in a rvide variety of configurations and represent a major extension of computation. They promise human-made device those perform function heretofore reserved for human beings. In present paper, artificial neural networks have been applied for face recognition model by backpropagation method using Delphi language. Nerv algorithm has been constructed and demonstrated according to the realiry concepts of a face recognition model. The result so obtained has classified the images of people in various posses and in different location rvith high accuracy.

Abstract

An image histogram is a chartthat sho、vs the distribution ofintensities in an irnage.The irnage histogram mnction creates plot by making n equaHy spaced bins each representing a range of data values,and then calculates the ntlmber of pixels within each range. Image enhancement that moditting the value of picture elements is a classical method for iFnprOVing the visual perception .Many digital enhancement techniques have been used in order to optinlize the、 .isual quality of image for human or machine vision throtlgh llistogranl nlodi「lcations. All these rnethods try to enhance the contrast ofthe input inlage、vithout rneasuring the contrast itsel■ In this paper t、vo histogra11l nlodi「lcation methods are introduced the flrst onc(histOgram stretching)depending on the maximum and minnlum brightness value in the image,while the second onc(histOgralu equalization) depend on the re-arrange the brightness values in the image. The experimental results indicate that the images more brightness after applying the two enhancement methods and the quality of the processed images is measured subjectively

Abstract

In this paper we consider F3/ /C.o* problem in which the processing order is assumed to be the same on each machine, the resulting problem is called the permutation flow shop problem. The objective is to find a processing order on each machine such that the makespan C*o* , which is the completion time of the last job is minimized. This problem is NP-hard, hence the existence of a polynomial time algorithm for finding an optimal solution is unlikely. This complexity result leads us to use an enumeration solution approach. In this paper rve proposc a branch and bound al-eorithm to solve this problem. Also we develop fast approximation algorithms yielding near optimal solution. We

Abstract

In this paper we introduce a new G-space which we call a generalized dispersive G-space. This space is weaker than a dispersive G-space which is introduced in [2] and stronger than a generalized cartan G-space which is introduced in [3]. We give the definition by depending on the defenition ofa generalized neighborhood rvhich itself depends on the concept of a generalized open set rvhich is introduced by N-Levin [6]. We study this space and give enough examples about it. Also we study its properties subspace, product space and the equivariant homeomorphic image. Finally we prove that a G-space X is a generalized dispersive G-space if X has a star thin generalized open set.

Abstract

The main purpose of this paper is to study the algebraic properties of a multiplication R-module Mwhenever the space lvla{fuL) of all maximal submodules of M is an irreducible space . We prove that Mar(lul) is irreducible if and only if the Jacobson radical J(0) of tvI is prime and if J(0)=0then Max(M) is irreducible if and only if I/is irreducible.Also we investigate the relation between Mar(M and Mar( R) if one of them is irreducible.
