Abstract: This paper presents a methodology for optimizing the allocation and sizing of distributed generators (DG) in electrical systems, aiming to minimize active power losses on transmission lines and maintain bus voltages within permissible limits. The approach consists of two stages. First, a sensitivity based analysis is used to identify the optimal candidate bus or buses for DG placement. In the second stage, a new random number generation method is applied to determine the optimal DG sizing. Moreover, a ranking for the optimal locations and sizes is given in case the optimal location is unavailable in real-world scenarios. The proposed methodology is demonstrated through a straightforward algorithm and tested on the IEEE 14-bus and IEEE 30-bus networks. Numerical simulations in MATLAB illustrate the effectiveness of the proposed approach in finding the optimal allocation of DG and the amount of active power to be allocated at the candidate buses, considering the inequality constraints regarding voltage limits and DG allowable power. The paper concludes with results, discussions, and recommendations derived from the proposed approach.

Research Title: Premature Avoidance in Genetic Algorithm using Dynamic Mutation Probability

Abstract: Evolutionary algorithms are optimization techniques based on biological and natural evolution mechanisms. These algorithms are a subset of evolutionary computation and fall under unsupervised learning. The Genetic Algorithm (GA) is one of the most common types of evolutionary algorithms. It begins with an initial set of candidate solutions and starts the evolutionary process by applying certain operators to generate new solutions. The newly produced solutions are expected to outperform the previous ones. Premature convergence is a problem encountered by most evolutionary algorithms, particularly genetic algorithms. It occurs when parental solutions fail to generate better offspring or children with superior traits. Self-adaptive mutations and Panmictic populations are the main factors contributing to premature convergence. Several approaches can be applied to avoid premature convergence and sustain population diversity, including the crowding method, incest prevention algorithm, scheduled sharing approach, cooperation-based approach, syntactic analysis of convergence, random offspring generation, selective mutation, and dynamic reproduction operators. The lack of population diversity leads directly to convergence, forcing the evolutionary algorithm to stop evolving and return the dominant value as the candidate solution. In most cases, this is not an optimal solution. One approach to sustaining population diversity is applying dynamic reproduction genetic operators. The main objective of this research is to propose an enhancement to the standard genetic algorithm to overcome premature convergence. A dynamic reproduction mutation operator is proposed to vary the probability of mutation based on the fitness value in each iteration. The methodology employed by the researcher involves conducting experiments to demonstrate the results achieved after applying the enhanced genetic algorithm (Rowe, 2008). Three different experiments with varying population sizes and mutation probability values were carried out to identify the best solution for an optimization problem. A total of 100 generations were produced by applying 10,000 iterations, and a binary genetic algorithm was used for running iterations with 16-bit chromosome lengths to represent candidate solutions. The results show that improvements in fitness scores were achieved, which enhanced the performance of the genetic algorithm for the produced generations (offspring). Moreover, population diversity was maintained.

Research Title: Enhanced Fitness Proportionate Selection Algorithm for Parent Selection in Genetic Algorithms

Abstract: Enhanced Fitness Proportionate Selection Algorithm for Parent Selection in Genetic Algorithms A genetic Algorithm is an evolutionary algorithm that models and simulates biological behavior, whether evolution or genetics, to reach a high-quality solution for search and optimization problems. There are many areas and applications to which genetic algorithms can be applied, like machine learning, feature selection, engineering design, and function optimization. Three leading operators must be applied to each generation's reproduction process; the first is the Selection process, which is applied to the initial population to select the candidate parents to mate and recombine to produce the next generation(offspring). The second operator is a crossover, which is applied to the selected parents from the previous operation (Selection) to make new individuals (offspring) carrying the same traits from parents by combining the parent's chromosomes; the last operator is a mutation, which is applied to the new offspring after crossover. Mutation operation aims to change the value of the chromosome gene randomly. In this research, the selection process will be demonstrated in detail. Then, fitness proportionate selection (FPS) will be presented as one of the most popular methods used in the selection process. The main problem of FPS is the candidate parent, which will mate and recombine to reproduce the next generation; in some cases, a strong individual can mate with a weak one and produce offspring with lower quality traits than the strong parents as a consequence of trait exchange, which happens between that pair. The researcher proposed an enhancement of the FPS algorithm to ensure that strong parents will mate and reproduce strong offspring and propagate their strong traits to the next generations; the proposed enhancement can be summarized as adding a step to the standards FPS to sort the selected individual in ascending or descending order after selection process and before applying cross over and mutation phases. The researcher conducted three experiments to prove the improvements in the fitness value as a consequence of applying that additional step in the selection algorithm; the experiments were performed with three different population sizes and reproduced 100 generations. The fitness score was measured in each generation, and the researcher presented the fitness score evolution over the GA iterations. The results were precise, proving that the sorted individuals after Selection gave better fitness scores than those obtained by applying the standard FPS.

Abstract: Background: The aim of this study was to explore the intention of Jordanian patients diag- nosed with hyperlipidemia to engage in physical activity. This objective was achieved via an in-depth analysis of how patient attitudes, subjective norms, and perceived behavioral control can influence patient intentions to exercise. Additionally, this research examined how sociodemographic factors and perceived barriers can impact patient participation in physical activity. Methodology: This study employed a cross-sectional approach on a con- venience sample of Jordanian patients diagnosed with hyperlipidemia. To gain the required data, a 15-item questionnaire (derived from the Theory of Planned Behavior) was presented to the participants in the form of an online survey (via several platforms, including What- sApp, Facebook, and email). Results: The results indicate that perceived behavioral control had a significant correlation with the participants’ intentions to participate in physical activ- ity. Additionally, the findings revealed that there were no significant correlations between demographic features (age, marital status, level of education, and monthly income) and intention to engage in physical activity. However, the results ascertained the existence of several facilitators to exercise (such as financial resource availability, self-interest, beneficial weather conditions, and supportive friends or exercise partners). The most commonly reported barriers to physical activity included time constraints, work commitments, and limitations imposed by existing health conditions. Conclusions: These findings provide valuable insights that can be employed to develop physical activity programs that address the cultural needs of Jordanian patients diagnosed with hyperlipidemia and enhance their levels of physical activity.

Abstract: As modern power systems continue to evolve with the integration of advanced technologies and a growing share of renewable energy sources, maintaining grid stability has become increasingly challenging. Variations in the fundamental frequency and the presence of harmonics can significantly affect the performance of electrical networks. To ensure a stable and reliable grid, continuous monitoring and protection are essential through digital measurements and frequency analysis. This study introduces a run-time testing model for protective frequency relays, utilizing the Wavelet transform as a signal decomposition. Known for its ability to analyze non-stationary signals, the Wavelet transform is applied in three testing configurations: run-time Simulink operation, a combination of Simulink and function-based testing, and run-time sampling for assessing over- and under-frequency relay performance. The model's effectiveness is evaluated based on several key factors, including system complexity, run time responsiveness, data sampling resolution, reaction time, and overall performance. Unlike traditional methods, this approach supports real-time signal decomposition, effective noise filtering, and accurate detection of transient faults. As a result, it delivers more reliable, responsive, and practical protection under the dynamic conditions of modern power grids.

Abstract: Background: Research is essential in nursing to augment the existing knowledge foundation underpinning the field, from education through practice and administration. To date, few studies have explored this topic in Jordan or the broader Middle Eastern region, and this study addresses this important gap. Objective: The objective of the current study was thus to examine the perspectives of Jordanian nurses concerning the practice of nursing research. Methods: In a cross-sectional descriptive study, 220 nurses from public, private, and academic institutions in Jordan were approached using a convenience sampling to complete the Boothe Attitudes Toward Nursing Research Scale. Results: The results showed that the overall mean score of all Boothe subscales was 3.289, SD = 0.968, reflecting practitioners’ uncertainty as a cohort in their attitudes toward research. Nurses exhibited somewhat favorable attitudes regarding the incentives and benefits associated with conducting nursing research, however (mean = 3.439, SD = 1.038). Statistically significant effects were also seen for participants’ level of education (F (2,218) = 39.993, p < 0.000), their personal interest in research (F (2,218) = 26.251, p < 0.000), and whether they received an incentive for doing studies. Conclusion: This study suggests that if hospital administrators work to collaborate with the academic institution to advance and facilitate higher education, they can improve patient outcomes by ensuring that more nursing practices are safe and evidence-based

Abstract: Skin wound infections pose a significant challenge for clinical treatment due to the development of biofilm. In this study, a wound dressing was employed to accelerate healing by enhancing the release and effectiveness of antimicrobial agents. pH-sensitive silica nanoparticles (SiNP) were designed to enable targeted drug delivery in both acidic and neutral wound environments, optimizing drug delivery. Chlorhexidine (CHX), a well-known antiseptic, was incorporated into SiNP using a layer-by-layer (LbL) coating method. The nanoparticles were characterized for size (TEM), surface charge (zeta potential), FTIR, TGA, CHX release. The CHX-loaded SiNP (CHX-SiNP) exhibited a 2–3 times higher release at pH 5 compared to pH 7.4. Additionally, CHX-SiNP demonstrated strong antibacterial activity against both Gram-negative and Gram-positive bacteria, without showing cytotoxicity in cell viability tests. To enhance usability, CHX-SiNP were incorporated into alginate hydrogels. Their antibacterial efficacy was further evaluated using artificial wounds created in an ex vivo human skin, where alginate-formulated CHX-SiNP treatment resulted in decrease in viable bacterial cells, compared to negative controls. These findings confirm that CHX-SiNP enable effective pH-responsive drug release, ensuring strong antibacterial performance. Furthermore, this study highlights the clinical potential of CHX-SiNP in treating wound infections.
