Nedal Mufleh Al Raheem Kawafhh

The purpose of this study is to investigate the effect of using technology in teaching science in Al Amal School in Amman on deaf studentsí performance. The researcher followed the equivalent pre/post T test two group designs. To achieve the aim of the study, a pre/post-test was constructed to measure deaf students' performance in science. The sample of this study consisted of 60 students; twenty eight male students and thirty two female students from Al Amal School for deaf students during the second semester of the academic year 2013/2014. The subjects of the study were distributed into two groups (experimental group and control group). The experimental group was taught science using technology while the control group was taught science using the traditional way of teaching. The subjects were 15 male students for the experimental group and 13 male students for the control group, while the female students for the experimental and control group were 15 and 17 respectively. Those subjects were distributed into two purposefully selected sections in Al Amal School in Amman. Descriptive statistical analyses were used (means and standard deviation) for the pre and post- tests of deaf students' science test to experimental and control groups. Comparison statistical methods were used (Two Way Anova) analysis of variance to make a comparison between the control and the experimental groups and gender variable (male and female). The findings of the study indicated that there were statistically significant differences in the post- test between the control and the experimental groups in favor of the experimental group, and there was no statistically significant difference in the deaf students' achievement due to gender. There was no statistically significant difference due to the interaction between gender and group. The researcher proposed some recommendations to enhance the effect of using technology in teaching science on deaf students' performance such as conducting further studies.

Biotechnology Contribution of Genetic Transformation: Fight against Viral and Bacterial Diseases Wheat Phytopathology
D.C. Tinak Ekom, M.N. Benchekroun, S.M. Udupa, D. Iraqi and M.M. Ennajibr />
Biotic stresses, especially bacteria and viruses, are among the primary causes of considerable wheat crop loss worldwide. These two diseases are spread differently. Bacteria are most often spread by wind, water and insects and they are kept in the seed, plant debris and soil whereas viruses are likely to be transmitted by aphids, leafhoppers, mites, soils contaminated with fungal vector and seed. Although a variety treatment with chemicals have been used to alleviate the problem of bacteria and viruses, genetic transformation seems to be an efficient and economic means of tailoring wheat crops to enable them to grow successfully in bacteria/viruses-prone environments. However, there is very few works done in this regard. In the majority of the cases, the genes showing expression in transgenic plants are stably inherited into the progeny without detrimental effects on the recipient plant.

Solving Coverage Problem in Wireless Camera-Based Sensor Networks by using a Distributed Evolutionary Algorithm

Ahmad Habibi Zadnavin

Wireless camera-based sensor networks have emerged as an important class of sensor-based distributed intelligent systems. These networks consist of large number of low-power camera nodes to monitor an environment such as airports, museums, traffic control, military applications etc. One of the more important problems in smart networks is camera coverage control. It is necessary to allow automatic tracking of targets and monitoring the environment without human intervention, allowing these systems to scale. Since this problem is NP-hard, even for static targets, so Meta heuristic method such as genetic algorithm, Particle Swarm Optimization have been proposed to achieve near-optimal solution, which are with high time complexity. To overcome problem the distributed particle swarm optimization is examined in this paper. Simulation results show that the distributed particle swarm optimization results near-optimal solution faster.

Stock Price Forecasting through Integration of Legendre Neural Network with a Random Time Strength Function in Metaallic Mineral Inductry of Tehran Stock Exchange

Ali Akbar Farzinfar and MohaddesehAbedini

Investment in stock market has turned out to be one of the most crucial sectors of society economy. That's why stock price forecasting is of great importance for stockholders. Stock market prediction has long been in the center of attention during financial time series forecasting. The present study was formulated in order to determine and forecast stock price through using an improved Legendre neural network in which Legendre polynomials are adopted for hidden layer activation function. Furthermore, since historical data are able to affect stock market fluctuations, a random time strength function is introduced in prediction model in order to weight each historical data. The function consists of drift and volatility functions showing effect of volatilities trend in random differential function on the mean time series and effect of volatilities in random differential function on time series variance, respectively. Four different algorithms with different pairs of drift and volatilities functions were designed for each firm in order to analyze the sensitivity of random time strength function. The obtained results via three determination criteria (i.e. RMSE, MAPE, and R2) indicated that use of both drift and volatilities functions in the prediction model results in fewer errors compared to three other algorithms. In other words, the given algorithm increases financial forecasting accuracy in the network.

Mohammad Emami, Seyed Hossein Iranmanesh and Masoud Oulapour

With regards to the decisive role of programs and projects in prosperity of enterprises, optimal selection becomes a serious challenge. Given the importance of this subject, multifunction committees in organizations generally make decisions by taking various criteria into account. Group decisions in these committees might be influenced by the moral and mental conditions of decision makers. This research was directed at designing a system capable of monitoring the procedure of decisions and to identify those cases that have a significant difference with previous decision trends. The architecture of this system is based on Adaptive-Network-based Fuzzy Inference Systems (ANFIS) and network training is conducted using gradient-based methods. The validity of systemís performance in terms of simulation of the teamís previous treatment is analyzed with the difference of two standard errors. It determined that the system follows up teamís treatment suitably. Decisions which are inconsistent with regular procedure can be extracted for approval by companyís managers. For making more successful decisions, this model provides an infrastructure. Frameworks designed for this study are applicable to a wide range of decisions made at project-based organizations.
