Quran has ten famous recitations and twenty different narrations. It is well known that the best way is to learn from qualified and authentic scientists (Sheikh's) in one or more of these narrations. Due to 1) the widespread of the Internet and the ease of use and availability of computers and the smart phones that enables access to the Internet;2) the business of people hindering them to attend physical learning environments;and 3) the very few number of elder licensed scientists, we have developed a virtual learning system (Electronic Miqra’ah). Scientists can supervise remotely the registered students. Students (from different ages) can register from anywhere in the world given that they have Internet connection. Students can interact with the scientist in real time so that they can help them memorize (Tahfeez), guide them for error correction, and give them lectures or lessons through virtual learning rooms. The targeted groups of users can be nonblind people, blind people, manual-disabled people and illiterate people. We have developed this system such that it takes the commands via voice in addition to the normal inputs like mouse and keyboard. Users can dictate the commands to the system orally and the system recognizes the spoken phrases and executes them. We have developed an efficient speech recognition engine that is speaker independent and accent independent. The system administrators create several virtual learning rooms and register the licensed scientists. Administrators prepare a daily schedule for each room. Students can register to any of these rooms by pronouncing its name. Each student is allocated a portion of time where he/she can interact directly by voice with the scientist. Other students can listen to the current student’s recitation and the error corrections, guidance or lessons from the scientists.

Educational System for the Holy Quran and Its Sciences for Blind and Handicapped People Based on Google Speech API

引用

Journal of Software Engineering and Applications 2014年第3期7卷 150-161页

作者： Samir A. Elsagheer mohamed Allam Shehata Hassanin mohamed Tahar Ben Othman Computer Engineering Department College of Computer Qassim University Qassim KSA Computer Science Department College of Computer Qassim University Qassim KSA Electronic Research Institute Giza Egypt

There is a great need to provide educational environments for blind and handicapped people. There are many Islamic websites and applications dedicated to the educational services for the Holy Quran and Its Sciences (Quran Recitations, the interpretations, etc.) on the Internet. Unfortunately, blind and handicapped people could not use these services. These people cannot use the keyboard and the mouse. In addition, the ability to read and write is essential to benefit from these services. In this paper, we present an educational environment that allows these people to take full advantage of the scientific materials. This is done through the interaction with the system using voice commands by speaking directly without the need to write or to use the mouse. Google Speech API is used for the universal speech recognition after a preprocessing and post processing phases to improve the accuracy. For blind people, responses of these commands will be played back through the audio device instead of displaying the text to the screen. The text will be displayed on the screen to help other people make use of the system.

Reference Point Based TR-PSO for Multi-Objective Environmental/Economic Dispatch

引用

Applied Mathematics 2013年第5期4卷 803-813页

作者： Ahmed Ahmed El-Sawy Zeinab mohamed Hendawy mohamed A. El-Shorbagy Department of Basic Engineering Science Faculty of Engineering Menoufiya University Shibin El-Kom Egypt Department of Mathematics Faculty of Science Qassim University Buraydah KSA

A reference point based multi-objective optimization using a combination between trust region (TR) algorithm and particle swarm optimization (PSO) to solve the multi-objective environmental/economic dispatch (EED) problem is presented in this paper. The EED problem is handled by Reference Point Interactive Approach. One of the main advantages of the proposed approach is integrating the merits of both TR and PSO, where TR has provided the initial set (close to the Pareto set as possible and the reference point of the decision maker) followed by PSO to improve the quality of the solutions and get all the points on the Pareto frontier. The performance of the proposed algorithm is tested on standard IEEE 30-bus 6-genrator test system and is compared with conventional methods. The results demonstrate the capabilities of the proposed approach to generate true and well-distributed Pareto-optimal non-dominated solutions in one single run. The comparison with the classical methods demonstrates the superiority of the proposed approach and confirms its potential to solve the multi-objective EED problem.

Shreadah National Institute of Oceanography and Fisheries Alexandria Egypt Chemistry Department College of Science King Khalid University Abha KSA Environmental Health Department High Institute of Public Health Alexandria University Alexandria Egypt

The residual concentrations of HCHs, TC, DDTs, THCs and PCBs were measured in Sparus auratus collected from the eastern and western sectors of the Egyptian Mediterranean Sea, as the most common fish species in the area. Gas chromatograph equipped with 63Ni-electron capture detector and 35% phenyl polysilphenylenesiloxane capillary column was used for the analysis and quantification after well-established extraction techniques. The concentrations (wet weight) of PCBs, DDTs, TCs, HCHs were: (1.87 - 616.66 ng·g-1), (0.42 - 98.28 ng·g-1), (0.06 - 2.94 ng·g-1), (0.35 - 11.77 ng·g-1), respectively in Sparus auratus collected from the eastern sector. However, these concentrations as wet weight in Sparus auratus from the western sector were: (5.75 - 605.53 ng·g-1), (1.53 - 226.47 ng·g-1), (0.09 - 8.12 ng·g-1), (0.26 - 5.80 ng·g-1), respectively. In general, concentrations of pesticides and PCBs in Sparus auratus either from the western or eastern Egyptian Mediterranean coast were far below the international permissible levels.

Explanation of Magnetic Destruction of Superconductor Using Schrodinger Equation in the Energy Space

引用

Natural Science 2020年第3期12卷 174-180页

作者： Einas mohamed Ahmed mohamed Mohammed Idriss Ahmed Mohammed Mubarak Dirar Abd-Alla mohamed Yahia Shergaui Saffa Elsiddig Abd Magid Department of Physics & Mathematics Faculty of Education Taif University Taif KSA University of Gezira Wad Medani Sudan Department of Physics Faculty of Science Sudan University of Science and Technology Khartoum Sudan Department of Physics Faculty of Art and Science at AL Muznab AL Qassim University AL Muznab KSA Department of Physics Faculty of Science and Technology Omdurman Islamic University Omdurman Sudan

The Wave function of Schrodinger Equation is expressed in terms of time dependent energy eigen function and spatial dependent wave function in the energy space, which gives spatial energy probability. This equation is utilized to find quantum momentum dependent on temperature. This in turn is used to find quantum complex resistance. This expression shows that the superconducting resistance vanishes for temperatures less than a certain critical value. This result conforms to superconductor conventional theory and empirical relations. The application of external magnetic field destroys superconductivity when its strength exceeds a certain critical value. The expression of the relationship between the critical magnetic field and the critical temperature is typical to the conventional one. This is the first time to obtain the conventional relationship for the superconductor’s resistance and critical magnetic field in one model in the energy space.

The Managerial Role of Pharmacist at Community Pharmacy Setting in Saudi Arabia

引用

Pharmacology & Pharmacy 2013年第1期4卷 63-70页

作者： mohamed N. Al-Arifi Clinical Pharmacy Department Director of Drug and Poison Information Center College of Pharmacy King Saud University Riyadh KSA

In Saudi Arabia community pharmacies by law, be owned and managed by pharmacists. Although these two functions seemed to be the same but in reality, they are not. Some studies showed that in community pharmacy managerial functions account for more than 50% of total routine and critical activity for all managerial position surveyed while other study showed that only 13.6% of the pharmacist’s time spent in administrative activities. This article addressed the role of the pharmacist as manager and the way in which he/she manages the pharmacy to ensure optimum productivity. The main part of this review discussed the managerial role of pharmacist in management of human resources, financial resources, marketing, inventory, information resources and space management of the pharmacy. Additionally, the management process, professional skills of managers, development of managerial skills, problems in management process and their resolution were also discussed. In addition to management functions which also include planning, organizing, leading, and controlling processes. The author concluded that the skills of pharmacy managers may vary because of the lack of formalized management training programs. To bridges a gap in management education, interested pharmacists should be encouraged to shift their career goals from professional to pharmacy administration. In addition, expansion of curricula in pharmacy management to include management training of highest possible caliber in managerial skills is highly demanded. Formalized management training programs for those involved in community pharmacy practice are also warranted.

Opto-Mechanical Properties of PTFE Fibres Using Phase Shifting Interferometry

引用

Optics and Photonics Journal 2014年第6期4卷 153-163页

作者： Khaled Yassien mohamed El Bakary 1Department of Physics Faculty of Science for Girls King Khalid University Abha KSA 2Department of Physics Aswan Faculty of Science Aswan University Aswan Egypt Department of Engineering Sciences Community College Umm Al-Qura University Mecca KSA

Polytetrafluoroethylene (PTFE) is one of a class of polymer that has many unique properties, which make it valuable in scores of applications. Here, the molecular alignment effect in fibre drawing and its relation with nonlinear optical properties of the PTFE fibres were studied by means of interferometry. For this propose, the phase shifting Mach-Zehnder interferometer was utilized. The fibre drawing device was attached to the interferometer for measuring the opto-mechanical properties of PTFE fibres. From the recorded interferomgrams the wrapped phase map and its contour line were determined using the phase shifting interferometry (PSI) method. From the contour lines the refractive index, refractive index profile, birefringence, polaryzability and orientation function of the investigated sample were determined at different draw ratios. The PSI method showed good results for enhancing the noisy fringe pattern and for obtaining contour line microinterferograms. This study offers the correlation between the mechanical properties and the structure properties of fibres. Thus, a better structure-property correlation can improve the technical and industry performance of the fibres.

Operation Research Based Techniques in Wireless Sensors Networks

引用

Communications and Network 2017年第1期9卷 54-70页

作者： Ahmed Redha Mahlous mohamed Tounsi Department of Computer Science Prince Sultan University Riyadh KSA

In recent years, we have seen an increasing interest in developing and designing Wireless Sensor Networks (WSNs). WSNs consist of large number of nodes, with wireless communications and computation abilities that can be used in variety of domains. It has been used in areas that have direct contact with monitoring and gathering data, to name few, health monitoring, military surveillance, geological monitoring (Earthquakes, Volcanoes, Tsunami), agriculture control and many more. However, the design and implementation of WSNs face many challenges, due to the power limitation of sensor nodes, deployment and localization, data routing and data aggregation, data security, limited bandwidth, storage capacity and network management. It is known that Operation Research (OR) has been widely used in different areas to solve optimization problems;such as improving network performance and maximizing lifetime of system. In this survey, we present the most recent OR based techniques applied to solve different WSNs problems: the node scheduling problem, energy management problems, nodes allocating issues and other WSNs related complex problems. Different Operational Research techniques are presented and discussed in details here, including graph theory based techniques, linear programing and mixed integer programming related approaches.

Updating Traditional 1/50,000 Topographic Maps Using Crowd-Sourced Geodata and Free Sources Satellite Images

引用

Journal of Geographic Information System 2021年第2期13卷 274-286页

作者： Atef Belhaj Ali mohamed Hafedh Hamza Department of Geography and GIS Faculty of Arts and Humanities King Abdulaziz University Jeddah KSA

This paper addresses how open geodata and crowd-sourced geodata, and the open geoportals might be integrated with the mainstream surveying and mapping practices to update traditional topomaps quickly and inexpensively, that might be otherwise impossible to do it due to economic and logistic situations. The abundant geographic data on the internet could be used to update topographic maps while avoiding the time-consuming nature of the traditional method. To be able to use them, it is necessary to measure and quantify the quality of these data, as well as to verify their credibility, in order to incorporate them into official topographic maps. The proposed approach takes advantage of neocartography, and it’s not about further developing a new approaches, but looking differently at how data is collected, assembled controlled and been used for updating topomaps. At the beginning, the methodology used about how open geodata and crowd-sourced geodata involved in collecting, simplifying, generalizing, controlling and generating useful cartographic information that complement traditional and conventional counterparts is presented. This methodology was applied on a 1/50,000 topomap located in the north of Jeddah city (western region of Saudi Arabia), and we have demonstrated that by using this type of data, it is possible to update topographic maps quickly and at a lower cost while maintaining cartographic precision and accuracy standards.
