From this conception the idea of this research become to develop an application working on the devices that supports Android environment, this application encrypt the SMS before it sends from sender and then decrypt it by using the same application when it arrives to the recipient. The goal from Using the encryption Operation of the SMS is to convince that the user is using a secure SMS application that it sends an encrypted SMS where in fact that is not the truth, but the application find the loophole to take the encrypted SMS and sends the encrypted SMS to the third party (hacker) where the user will not noticed that the SMS went to the third party. Java language and an android developer tools like (ECLIPS) and other tools where used to build this application. This application is working on android environment and also needs a little space of memory and it works without leaves anything that refers to the third-party.","PeriodicalId":15614,"journal":{"name":"JOURNAL OF EDUCATION AND SCIENCE","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83118473","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We proposed two spectral modifications to the conjugate descent (CD). These two proposed methods produces sufficient descent directions for the objective function at every iteration with strong Wolfe line searches and with inexact line search, and also they are globally convergent for general non-convex functions can be guaranteed. Numerical results show the efficiency of these two proposed methods. A Global Convergence of Spectral Conjugate Gradient Method for Large ... 144 Introduction. Let R R f n → : be continuously differentiable function. Consider the unconstrained nonlinear optimization problem: Minimize f(x), n R x . (1) We use g(x) to denote to the gradient of f at x. Due to need less computer memory especially, conjugate gradient method is very appealing for solving (1) when the number of variables is large. A conjugate gradient (CG) method generates a sequence of iterates by letting 1 1 1 − − − + = k k k k d x x  , k=0,1,2,... (2) where the step-length k  is obtained by carrying out some line search, and the search direction k d is defined by     + − = − = − 1 0 , , 1 k if d g k if g d k k k k k  , (3) where k  is scalar which determines the different CG methods [11]. There are many wellknown formula for k  , such as the Fletcher-Reeves(FR) [7], Polak-Ribirere-Polyak (PRP) [13] and [14], Hesteness-Stiefel (HS) [10], conjugate descent (CD) [8], Liu-Story (LS) [12], and Dai-Yuan (DY) [5]. In survey paper Hager and Zhang in [9] reviewed the development of different various of nonlinear gradient methods, with especial attention given to global convergence properties.
