Real-Time System: Fire and Smoking Control System (Case Study)
Muhammed Ali Suliman Mesleh,Mohammed Ashraf Zoghoul
World of Computer Science and Information Technology Journal , 2013,
Abstract: A real-time system is software where the correct functioning of the system depends on the results produced by the system and the time at which these results are produced. The main objective of this study is to show the importance of real-time system as an application that uses computer system in the human life. Since it helps to control vital and dangerous aspects, that otherwise can not be controlled.The motivation for this study is to avoid fire occurrence and smoking habits in certain places. Since by using this system the place and time of event can be determined in short period. For that reason, the need for using real-system raised.
Jordan Software Industry: Investigating the Role of Human Capital
Ashraf Bany Mohammed
International Journal of Business and Management , 2011, DOI: 10.5539/ijbm.v6n5p217
Abstract: Software industry is realized as one key opportunity for socio-economic development, especially for developing countries. Human Capital heavily plays a critical role in such knowledge-based sectors as software. This paper describes and analyzes the role of human capital in the development of Jordan software industry between 1980’s and 2005. In doing so, different roles in software industry are identified, described and analyzed. The study suggests that the existence of some levels of professional, technical and ICT graduates, will not guarantee the development of the sector. Quality, proper utilization, collaboration and policy coherency of Human Capital is needed for software sector development. Moreover, we argue that challenges such as Diaspora can have a positive impact through technology transfer and entrepreneurship as the Indian case suggests.

Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.33026
Abstract: The identification of control chart patterns is very important in statistical process control. Control chart patterns are categorized as natural and unnatural. The presence of unnatural patterns means that a process is out of statistical control and there are assignable causes for process variation that should be investigated. This paper proposes an artificial neural network algorithm to identify the three basic control chart patterns; natural, shift, and trend. This identification is in addition to the traditional statistical detection of runs in data, since runs are one of the out of control situations. It is assumed that a process starts as a natural pattern and then may undergo only one out of control pattern at a time. The performance of the proposed algorithm was evaluated by measuring the probability of success in identifying the three basic patterns accurately, and comparing these results with previous research work. The comparison showed that the proposed algorithm realized better identification than others.
Multi-Team Bertrand Game with Heterogeneous Players  [PDF]
Mohammed Fathy Elettreby, Daoud Suleiman Mashat, Ashraf Mobarez Zenkour
Applied Mathematics (AM) , 2011, DOI: 10.4236/am.2011.29164
Abstract: In this paper, we proposed a general form of a multi-team Bertrand game. Then, we studied a two-team Bertrand game, each team consists of two firms, with heterogeneous strategies among teams and homogeneous strategies among players. We find the equilibrium solutions and the conditions of their local stability. Numerical simulations were used to illustrate the complex behaviour of the proposed model, such as period doubling bifurcation and chaos. Finally, we used the feedback control method to control the model.
Liver fibrosis recognition using multi-compression elastography technique  [PDF]
Ashraf Ali Wahba, Nagat Mansour Mohammed Khalifa, Ahmed Farag Seddik, Mohammed Ibrahim El-Adawy
Journal of Biomedical Science and Engineering (JBiSE) , 2013, DOI: 10.4236/jbise.2013.611129
Abstract: Liver fibrosis recognition is an important issue in diagnostic imaging. The accurate estimation of liver fibrosis stages is important to establish prognosis and to guide appropriate treatment decisions. Liver biopsy has been for many years the reference procedure to assess histological definition for liver diseases. But biopsy measurement is an invasive method besides it takes large time. So, fast and improved methods are needed. Using elastography technology, a correlation technique can be used to calculate the displacement of liver tissue after it has suffered a compression force. This displacement is related to tissue stiffness, and liver fibrosis can be classified into stages according to that displacement. The value of compression force affects the displacement of tissue and so affects the results of the liver fibrosis diagnosing. By using finite element method, liver fibrosis can be recognized directly within a short time. The proposed work succeeded in recognizing liver fibrosis by a percent reached in average to 86.67% on a simulation environment.

Ashraf Ali Wahba, Nagat Mansour Mohammed Khalifa, Ahmed Farag Seddik, Mohammed Ibrahim El-Adawy
Journal of Biomedical Science and Engineering (JBiSE) , 2014, DOI: 10.4236/jbise.2014.75032
Abstract: Breast cancer recognition is an important issue in elastography diagnostic imaging. Breast tumor biopsy has been for many years the reference procedure to assess histological definition for breast diseases. But biopsy measurement is an invasive method besides it takes larger time. So, fast and improved methods are needed. Using elastography technology, a digital image correlation technique can be used to calculate the displacement of breast tissue after it has suffered a compression force. This displacement is related to tissue stiffness, and breast cancer can be classified into benign or malignant according to that displacement. The value of compression force affects the displacement of tissue, and then affects the results of the breast cancer recognition. Finite element method was being used to simulate a model for the breast cancer as a phantom to be used in measurements and study of breast cancer diagnosis. The breast cancer using this phantom can be recognized within a short time. The proposed work succeeded in recognizing breast tumor phantom by an average correct recognition ratio CRR of about 94.25% on a simulation environment. The strain ratio SR for benign and malignant models is also computed. The result of the simulated breast tumor model is compared with real data of 10 lesion cases (6 benign and 4 malignant). The coefficient of variation CV between the simulated SR and the SR using real data reaches to about 5% for benign lesions and 4.78% for malignant lesions. The results of CRR and CV in this proposed work assure that the proposed breast cancer model using finite element modeling is a robust technique for breast tumor simulation where the behavior of real data of breast cancer can be predicted.

Open Journal of Therapy and Rehabilitation (OJTR) , 2014, DOI: 10.4236/ojtr.2014.24025
Abstract: Background and Purpose: Carpal tunnel syndrome (CTS) is a common source of hand numbness and pain. The goal of this study was to compare longitudinal stretching of muscles and nerve to deep transverse friction massage for decreasing pain and improving hand function in patients with chronic CTS. Subjects and Methods: Thirty patients, 25 to 40 years old, were included in this study and randomized into two groups: the first group (36.8 ± 0.262) followed a physical therapy program group receiving stretching of wrist and hand flexors in combination with ultrasound, strengthening exercises of wrist and hand flexors, and wrist splint, three sessions per week for 12 weeks; and the second group (35.9 ± 0.225) followed the physical therapy program of deep transverse friction massage on the carpal tunnel site at the wrist joint, with using ultrasonic therapy, strengthening exercises of wrist and hand flexors and wrist splint, three sessions per week for 12 weeks. Outcome measures were range of motion (ROM), pain using visual analog scale (VAS), and hand grip strength measured with a sphygmomanometer. Results: There was a significant difference in both groups in all outcome measures compared to baseline. Over stretching group showed significant difference at the end of study in terms of range of motion of wrist flexion, extension and strength of handgrip when compared to deep friction massage group P < 0.05. However, there is no significant difference between groups in pain. Discussion and Conclusion: This study showed that the effect of stretching exercises is more beneficial than deep transverse friction massage in the treatment of patients with CTS in decreasing the compression of the median nerve in the tunnel.

Journal of Software Engineering and Applications (JSEA) , 2015, DOI: 10.4236/jsea.2015.810053
Abstract: Computer Based Assessment (CBA) is being a very popular method to evaluate students’ performance at the university level. This research aims to examine the constructs that affect students’ intention to use the CBA. The proposed model is based on previous technology models such as Technology Acceptance Model (TAM), Theory of Planned Behavior (TPB), and Unified Theory of Acceptance and Usage of Technology (TAUT). The proposed CBA model is based on nine variables: Goal Expectancy, Social Influence, Facilitating Conditions, Computer Self Efficacy, Content, Perceived Usefulness, Perceived Ease of Use, Perceived Playfulness, and Behavioral Intention. Data were collected using a survey questionnaire from 546 participants who had used the computer based exam system at the University of Jordan. Results indicate that Perceived Playfulness has a direct effect on CBA use. Perceived Ease of Use, Perceived Usefulness, Computer Self Efficacy, Social Influence, Facilitating Conditions, Content and Goal Expectancy have only indirect effects. The study concludes that a system is more likely to be used by students if it is playful and CBA is more likely to be playful when it is easy to use and useful. Finally, the studied acceptance model for computer based assessment explains approximately only 10% of the variance of behavioral intention to use CBA.
