The research aims to build an educational program - learning, according to the concepts of renewable energy and nanotechnology And knowledge of its impact on the technological enlightenment when the third phase students in the Department of Chemistry, and to verify the goal and put the researcher null hypothesis the following: No Statistically significant difference at the level (0.05) between the average scores of the experimental group students who are studying material nanotechnology and renewable energy program Altalima- learning and the average score for the control group of students who are studying the same article the usual way in technological enlightenment. The search was limited to the third row in the Department of Chemistry, College of Education, Science Pure students -bn Haytham for the academic year 2014-2015m, was preparing the content of scientific material to include renewable energy concepts and nanotechnology, with the two groups experimental design was chosen. One of them set the other part restraint Odhu post-test design was chosen for research and the Department of Chemistry in the College of Education, Pure Science - Ibn al-Haytham Sample deliberate research because it is more convenient to carry out the experiment, were selected Mjootain (A, B) at random to represent the experimental group of (24) students and two groups (C, D) to represent the control group of (23) students, and held them equal in the number of variables, the experimental group was taught according to the program Altalima- learning and studying the second (control) in the usual way by the subject teacher for both groups and to measure the impact of the program in technological enlightenment was built search tool created by of building technological enlightenment scale which consists of (36) Positive paragraph (2), paragraph revealing was sure of his sincerity and persistence, was applied experience over the first semester by a lecture and one to two hours a week and applied technological enlightenment scale dimensionally on the two groups on 28 / 29/01/2015 m respectively, and use the samples t-test (t-test) The Pearson correlation coefficient and averages as a means of statistical data processing results were that there is a difference statistically significant between the average scores of the experimental group students and average grades control group students in technological enlightenment scale in favor of the experimental group were rejected null hypothesis, and in the light of the results and put the researcher set of recommendations and proposals .

Cognitive Implications of Usage-Based Approach: رغد فهمي اعجمي
...Show More Authors

Tremendous efforts have been exerted to understand first language acquisition to facilitate second language learning. The problem lies in the difficulty of mastering English language and adapting a theory that helps in overcoming the difficulties facing students. This study aims to apply Thomasello's theory of language mastery through usage. It assumes that adults can learn faster than children and can learn the language separately, and far from academic education. Tomasello (2003) studied the stages of language acquisition for children, and developed his theory accordingly. Some studies, such as: (Ghalebi and Sadighi, 2015, Arvidsson, 2019; Munoz, 2019; Verspoor and Hong, 2013) used this theory when examining language acquisition. Thus,

Implementation of Neural Control for Continuous Stirred Tank Reactor (CSTR)
...Show More Authors

In this paper a dynamic behavior and control of  a jacketed continuous stirred tank reactor (CSTR)  is developed using different control strategies, conventional feedback control (PI and PID), and neural network (NARMA-L2, and NN Predictive) control. The dynamic model for CSTR process is described by a first order lag system with dead time.

The optimum tuning of control parameters are found by two different methods; Frequency Analysis Curve method (Bode diagram) and Process Reaction Curve using the mean of Square Error (MSE) method. It is found that the Process Reaction Curve method is better than the Frequency Analysis Curve method and PID feedback controller is better than PI feedback controller.

The results s

Analysis of the tax policy strategy and its impact on the technical regulation of taxes (tax price)
...Show More Authors

The research aims to identify the tax policy strategy adopted in Iraq after the change of the tax system in 2003 and beyond, and then make a comparison of the two strategies on corporate data whether they are charged with progressive tax rates and after the change of the system as the tax rates became fixed, and then indicate the changes In the tax proceeds, and knowing the dimensions of the approved tax policy, is it a tax reform strategy or a strategy to attract investments.

The research started from the problem of exposure of the Iraqi tax system to several changes in the tax strategy from 2003 until now, as this led to a reflection on the technical organization of taxes, in terms of the tax exemption.And these many amendments

Interior Visual Intruders Detection Module Based on Multi-Connect Architecture MCA Associative Memory
...Show More Authors

Most recent studies have focused on using modern intelligent techniques spatially, such as those
developed in the Intruder Detection Module (IDS). Such techniques have been built based on modern
artificial intelligence-based modules. Those modules act like a human brain. Thus, they should have had the
ability to learn and recognize what they had learned. The importance of developing such systems came after
the requests of customers and establishments to preserve their properties and avoid intruders’ damage. This
would be provided by an intelligent module that ensures the correct alarm. Thus, an interior visual intruder
detection module depending on Multi-Connect Architecture Associative Memory (MCA)

Study the influence of the reinforced material geometrical shape on the internal stresses in the composite materials
...Show More Authors

In this paper the reinforced materials manufactured from steel continues fibers are used in Aluminum matrix to build a composite material. Most of researches concentrated on reinforced materials and its position in the matrix according to its size and distribution, and their effects on the magnitude of different kinds of the stresses, so this paper presents and concentrate on the geometrical shape of reinforced material and its effects on the internal stresses and strains on the composite strength using FEM as a method for analysis after loaded by certain force showing the deference magnitudes of stresses according to the different geometrical shapes of reinforced materials.

A Comprehensive Review on Medical Image Steganography Based on LSB Technique and Potential Challenges
...Show More Authors

The rapid development of telemedicine services and the requirements for exchanging medical information between physicians, consultants, and health institutions have made the protection of patients’ information an important priority for any future e-health system. The protection of medical information, including the cover (i.e. medical image), has a specificity that slightly differs from the requirements for protecting other information. It is necessary to preserve the cover greatly due to its importance on the reception side as medical staff use this information to provide a diagnosis to save a patient's life. If the cover is tampered with, this leads to failure in achieving the goal of telemedicine. Therefore, this work provides an in
