Abstract: Abstract— A Genetic Algorithm (GA) is a high-level procedure applied to find, generate or select a good solution for an optimization problem, usually in imperfect or limited computation capacity, based on the Evolutionary Algorithms (EA). In this paper, we propose a clonal selection algorithm for the synthesis of a data transmission network topology, which unlike former works, depends on the model cost to determine the optimality value which solves the problem of distributing information flows in a network, and abilities of communication channels (available channel capacity). The proposed genetic synthesis algorithm solves the optimizing criteria, taking into account the optimal trade-off between the network dependability and cost. Finally, the algorithm was applied over the Jordanian cities where each city represents an algorithm node. The outcome of this application shows the gained improvement of the proposed algorithm.

Research Title: Determining the Optimum Number of Paths for Realization of Multi-path Routing in MPLS-TE Networks
Author: Mohammad Alhihi, Published Year: 2018
Faculty: Faculty of Engineering

Abstract: Multi-Protocol Label Switching for Traffic Engineering (MPLS-TE) technology is an intelligent and advanced tool for handling traffic through the core networks and implementing new services based on virtual transport. Since MPLS-TE combines channel and network layer mechanisms, network administrators can optimally integrate and allocate the traffic loads while maintaining the speed of technologies such as Asynchronous Transfer Mode (ATM) technology. In this paper, the problem of the developed algorithm of multi-path routing which allows us to determine the optimum number of independent shortest paths is theoretically solved. In details, the article proposes a way for finding the set of shortest paths using Dijkstra's algorithm, and then determination of the maximum flow for each of the shortest paths based on the mathematical concepts and finally, introducing the solution of the multi-criteria optimization problem for a set of shortest paths. According to our approach, optimizing the use of resources in the core networks is possible with using the MPLS-TE technology.

International Journal on Energy Conversion (IRECON), Vol 5, No 5, 2017.
Faculty: Faculty of Engineering

Abstract: This paper presents a new approach for the estimation of the load loss factor. This factor is essential to calculate the electrical energy losses in electrical power distribution networks. The represented approach can estimate the loss factor, especially for those distribution lines which their load profile has tedious to repetition and routine character like in industrial plants or for any other objects with similar load profile. A mathematical formulation of the problem has been developed and solved. The equivalent working hours (T (eq.)) are calculated based on a newly derived equation. The (T(eq.)) value leads to determine the amount of electrical energy losses in distribution lines. A numerical example and discussion have been presented to illustrate the significance of the proposed method.

Abstract: Allowing the dust to accumulate on solar panels without adequate cleaning leads to huge monetary losses. Proper judgment of when to call for washing of solar panels is a compromise between gross costs of cleaning the panels and how much reduction in efficiency of solar panels can be tolerated. In this paper, we derive a formula for the optimal number of days between cleaning cycles of a solar array by minimizing the cost of cleaning the array and the lost revenue from the unclean panels. The formula will aid in deciding cleaning periods based on the environment in which the solar panels are installed and cost incurred from undertaking the washing process.

Abstract: Aim and objectives: To illustrate the Palestinian community’s views, opinions and stances about the concept of do-not-resuscitate for terminally ill patients. Background: Do-not-resuscitate orders are practised in many countries worldwide, but there is no consensus on their practice in the Middle East. Do-not-resuscitate orders may be applied for terminally ill paediatric patients. Some studies have been conducted describing people’s experiences with these do-not-resuscitate orders. However, few studies have considered community perspectives on do-not-resuscitate orders for terminally ill patients in Palestine. Design: A descriptive-qualitative design was adopted. Methods: A purposive sample of 24 participants was interviewed, with consideration of demographical characteristics such as age, gender, education and place of residency. The participants were recruited over a period of 6 months. Individual semistructured interviews were utilised. These interviews were transcribed and analysed using thematic analysis. Findings: Significantly, the majority of the participants did not know the meaning of do-not-resuscitate and thought that removal of life-sustaining devices and do-notresuscitate were the same concept. Most of the interviewees adopted stances against do-not-resuscitate orders. Several factors were suggested to influence the decision of accepting or rejecting the do-not-resuscitate order. The majority of the participants mentioned religion as a major factor in forming their viewpoints. The participants expressed different views regarding issuing a law regarding do-not-resuscitate orders. Conclusion: Our findings provide a unique understanding that there is a general misunderstanding among our participants regarding the do-not-resuscitate order. Further research with policymakers and stakeholders is still required.

Abstract: System dynamics have been used for the planning of different sectors in the electric power industry. In the last decade, the number of new suppliers/ consumers entered into the electric power system is rapidly increasing; they are respectively the renewable energy and electric cars. This necessitates a mechanism to estimate the demand for electricity in the near future as per as to evaluate and forecast the situation in the power system. The amounts of generation, transmission, and distribution have been modeled in the form of regression equations depicting the system. The developed methodology is based on system dynamics and a new concept of trend index is introduced. The data of the Jordanian electric power system for the period (2001-2016) has been investigated and analyzed. The analyzed period is divided into two equal periods, the first (2001-2008); is to perform a comparative study of the status and the performance of the power system. However, the second period (2009-2016); is used to investigate the trends of the electrical power system. Numerical examples illustrating the effectiveness of the proposed method are presented. Discussion, conclusions, and recommendations on the accuracy of the achieved results are also introduced.

Research Title: A New Algorithm for Reactive Power Compensation in Industrial Plant

Jordan Journal of Electrical Engineering (JJEE), Volume 2, Number 3,
Faculty: Faculty of Engineering

Abstract: This paper presents a method based on Lagrange multipliers for capacitor banks allocation at industrial plant networks. The aim of compensation is to avoid penalties in (JD/$) raised on electricity bills due to low power factor and to minimize the power losses at the plant’s network. Capacitor banks will be allocated at the main board (MB) as a fixed type and at secondary distribution boards (SDB) as a regulated type. For this regard, a mathematical formulation of the problems along with concentrates has been established and solved. The “equivalent consumed active energy” amount is calculated based on a newly devolved equation for finding the “equivalent working time” which leads to calculating the total amount of reactive power compensation. The proposed method is applied to the data extracted from the monthly electricity bill of an industrial plant network. A numerical example and discussion have been introduced to illustrate the effectiveness of the proposed method.

Abstract: Nonfatal injuries are considered as one of the major public health hazards affecting schoolchildren, and the majority of these injuries occur at school or in the home. A cross-sectional study was conducted over a period of 3 months, March–May 2015. The participants were 4,355 Jordanian schoolchildren in Grades 7–12. The Pearson w2 test was computed, and the odds ratio was used to determine the magnitude of various risk factors for nonfatal injuries among schoolchildren. The overall incidence of nonfatal injury was 33.9%. The group most likely to sustain nonfatal injuries was boys, aged 12–15, in Grade 7, whose parents had a low level of education or a high family income. Injury prevention in schools and at homes is a cornerstone for protection or reducing the incidence of injuries. School nurses have a duty to follow up and examine the accident reports and evaluate whether safety policies are applied and are effective in different school settings. Furthermore, health and education authorities should develop a national program for preventing injuries.

Abstract: Safe drinking water is crucial for the well-being of current and future generations. This study aims to evaluate the quality of potable water in Baghdad city. Furthermore, this study compares the quality of tap and bottled water. Baghdad city was divided into 4 districts based on the water source, and 40 water samples were collected from each district. Moreover, the most popular bottled water brands were sampled and compared with the tap water samples. The quality of the analyzed potable water samples varied based on the water source. The total dissolved solid (TDS) levels exceed the palatable (>600 ppm) water levels in some districts. In addition, the concentration of sulfate was relatively high in both tap and bottled water and ranged from 200 to 330 ppm. The bottled water quality was within the acceptable limits set by the World Health Organization, but the TDS levels were relatively high. The hardness, Cl−, Pb2+, and bacteria contents in both tap and bottled water were within the standard limits. Finally, it is important to conduct radiological analyses in the future to investigate the effect of wars on Iraqi water resources.
