Expert Database Administrator

I have a great experience in database administration, installation, monitoring, problem solving, backup, recovery, and auditing, with more than 10 years experience. Besides, carrying out database tuning activities to ensure optimal performance. I like working with Oracle database, forms, and reports, starting from small application extending to large projects, and from Oracle 6i to Oracle 12c. I am passionate about new topics and technologies of a database, also passionate about creating the best solutions I can work along well in cooperation with the whole team and manage them also efficiently, or work individually. I'll be glad to cooperate with you! I will be responsible to complete the task within the agreed deadline and with full accuracy. Database: Oracle NoSQL Couch & Mongo Microsoft Access Microsoft SQL Server MySQL Programming: C++ Java Data: Excel Data Processing & Mining Security: Computer Security Cryptography Others: Algorithms Matlab and Mathematica OCR

A Fast Parallel Alpha-Beta Algorithm for Tic TAC Toe Game

International Journal of advanced and innovative Research (IJAIR)

A proposed parallel implementation version of the alpha-beta algorithm. A pool master-slave model is used in which the master process is given the Root node and divides the nodes among the workers. During computation, a worker which updates the values of alpha or beta sends the updated values to the master. Worker which still has a work to do requests the work from the master and then the master sends the updated values to this specific worker, thus, reducing the communication overhead.

Using Foreign Agent For Home Agent Fault Tolerance in Mobile IP

International Journal of advanced and innovative Research (IJAIR)

In this paper, We are proposing to make use of Foreign Agents as redundant (Backup) for Home Agents, i.e. copying the needed data to a foreign agent to act as a Backup of the Home Agent at the point of failure. Any CN that wants to communicate with a MN should connect to a third party for the address of the failure-free agent that has the current location of that MN. In this way, the whole home network can be backed up

CAP Theorem vs. CAS Principle in Computer Networks

International Journal of advanced and innovative Research (IJAIR)

• Previously no body talks as we know about the relation between scalability, availability and consistency in computer networks, although the scalability is important issue. In this paper we study the tradeoff between consistency, availability and scalability to see if it possible to meet all of them in the network at the same time, and we found that we can not keep them together simultaneously in the same network. We used two simulators NS2 and OPNET simulator to achieve this result.

Cryptography Using Multiple Two-Dimensional Chaotic Maps

International Journal of Computer Network and Information Security (IJCNIS)

symmetric key block cipher cryptosystem is proposed, involving multiple two-dimensional chaotic maps and using 128-bits external secret key. It produces ciphertext with random distribution. The computation time is much less than previous related works. Theoretic analysis verifies its superiority to previous cryptosystems against different types of attacks

Cryptography Using Quasi Group and Chaotic Maps

International Technology and Science Publications (ITS) - Data Research

A symmetric key cryptosystem is proposed, involving chaotic maps and quasi-group. The proposed cryptosystem destroys any existing patterns in the input, and also, it maximizes entropy. Moreover, the n-grams illustrate that the proposed cryptosystem is secure against the statistical analysis. Furthermore, Experimental results show that the ciphertext has good diffusion and confusion properties with respect to the plaintext and the key
