2018-05-232018-05-2351Implicit in the development of parallel programming language using Visual Basic
http://journals.uokufa.edu.iq/index.php/jkmc/article/view/7153
Several studies have been performed to investigate the benefits of parallel programming models, and compared the models with same language family. The parallel technique is applicable only when the programmer has a single computer with multiple processors to perform various tasks individually or the programmer number of different computers connected by a single network. Parallel programming model in computing is an idea of parallel computer architecture. This research introduced the concept of parallel programming models and languages. The present research mainly focused on the different parallel programming models proposed by previous researchers using distinct programming languages. Through analyzing the strengths and weaknesses of various programming models used for parallel computing, a new model is developed. Along with this, the concept of OOP (Object-oriented programming) in the context of parallel computing is also discussed. This research proposed a model named as Asynchronous Dynamic load Balancing (ADLB). ADLB model used MPI as avehicle for library implementation rather as an end-user programming systemZainab fahad mhawes al-naseri

http://journals.uokufa.edu.iq/index.php/jkmc/article/view/7154
In this work, we submite and study a newlclass of meromorphiccmultivalent functions defined by fractional differ-integral operator . We gain some geometric properties , such as, coefficient inequality, growth and distortion bounds, convolution properties, integral representation, radii of starlikeness and convexity, extreme points, weighted mean and arithmetic mean for functions belonging to the classWaggas Galib AtshanNajah Ali Jiben Al-Ziadi

2018-05-232018-05-2351On optimal periodic solution of differential equations
http://journals.uokufa.edu.iq/index.php/jkmc/article/view/7155
this paper dedicated to the construction of solution of a three time scale periodic singular perturbed non-linear quadratic optimal control problem by using the direct method. The algorithm of the method is the direct substitution of the postulated asymptotic expansion of the solution of the problem and then by the conditions of the problem we constructed of a series of problem and find terms of the asymptotic. We find the solution by using the Hamilton's function and maximum principleMethaq Hamza Geem

2018-05-232018-05-2351A classical approach for hiding encryption key in the same encrypted text document
http://journals.uokufa.edu.iq/index.php/jkmc/article/view/7156
Data encrypting and steganography techniques each have its own merits and weaknesses. Crackers and hackers developed many software applications that can attack the weakness of these techniques and thus can reach to the meaning of the private information and its existence. In this paper, a simple technique is proposed to make use of encrypting and steganography merits simultaneously, and thus makes any attempt for breaking both techniques at the same time harder than applying each of them alone. The proposal uses English, Arabic, or mixed writing plain text. Encrypting the text by AES-encrypting algorithm with an encryption key of 128 bit long and then hiding the encrypted text with only one part of the encrypting key (sender key only), in another English/Arabic (cover), plain text. The text hiding technique is done according to the nonprintable characters of the Unicode character set method. The proposed technique is coded into a form of Matlab program. Experimenting with this paper technique shows how difficult to break the system and thus can applying it in emailing private documents between users connected to a virtual network on an insecure public channelProf. Dr. Taleb A.
