THE EFFECT OF SUCTION ON THE BOUNDARY LAYER SEPARATION OF A RETARDED BOUNDARY LAYER FLOW
type: item
description: Boundary layer separation is one of the most drawback phenomena that reduces or even eliminates the lifting force generated by the flow over an airfoil. Boundary layer flow separation occurs due to an increasing adverse pressure gradient in the flow direction. Boundary layer theory fails to predict and describe this singularity where shear stress vanishes in the vicinity of the wall. To generate this phenomenon for a laminar flow over a flat plate in the presence of a pressure gradient, the linearly retarded flow of Howarth has been used. The decelerating non-similar free-stream velocity profile becomes increasingly S-shaped and finally separates downstream. The numerical solution of the considered flow reproduced the theoretical result reported by Howarth for the location of the separation point which is approximately (x sep / L = 0.125). A suction strategy is applied over the wall which tends to shift the location of the separation point far downstream or completely suppresses its formation.

Reviving Heritage Building Façades After Disasters: The Case of Derna Following Storm Daniel in Light of Historic Urban Design Standards
type: item
description: Historic cities often suffer significant architectural losses during natural disasters, particularly the façades of heritage buildings that embody urban identity and cultural memory. This study aims to explore the potential for reviving historical façades damaged by disasters in accordance with the design standards of traditional urban fabrics, using the case of Derna, Libya, following the 2023 Storm Daniel disaster. The research adopts a multi-layered analytical methodology that combines literature review, architectural analysis, and field documentation, supported by interviews and local sources. It examines the extent of damage to the façades in Derna’s old city and assesses the feasibility of reconstructing them in a way that preserves their original character while meeting contemporary standards of safety and sustainability. Furthermore, the study evaluates the alignment of proposed reconstruction efforts with international heritage charters, and presents a phased implementation plan that includes legal, technical, and community-based recommendations. The findings affirm that revitalising the facades of historic buildings in Derna is not only feasible but vital for restoring the city's collective urban memory—provided that the process follows a scientifically grounded, participatory approach that balances authenticity with innovation.

Prediction of Pavement Condition Index using Artificial Neural Networks
type: item
description: Modern pavement management systems aim to maintain performance and prioritize maintenance, reducing costs, and optimizing resources. Pavement Condition Index (PCI) is one of the most accurate tools to assess the structural condition of pavement, as it relies on evaluating various pavement distresses and converting them into a numerical value describes the pavement condition. This study aims to build a machine learning model to predict the pavement condition index using artificial neural networks (ANN). Three ANN models with different number of layers and nodes were designed for comparison. All models had one input layer consisting of seven types of pavement distresses, and one output layer consisting of the PCI value. Three models had one hidden layer with 4, 8, and 16 nodes. The data was normalized with a single weight scale by converting the descriptive data into numerical values and then calculating the weights for each type of distress according to its severity level. The results revealed that models had a coefficient of determination exceeding 0.95, which indicated the capability of artificial neural networks to model complex nonlinear relationships. Comparing the three models, the (7-8-1) architecture demonstrated the highest level of reliability with R2 achieving 0.98 and a standard error of less than 4%. In addition, K-fold cross-validation approach with 5-folds was conducted to validate the model. The average results of folds showed R2=0.95 and RMSE=5.72±0.49 which confirm the model's reliability in calculating PCI and assisting pavement M/R decision makers.

Model Predictive Control for Stabilizing Quadcopter Flight and Following Trajectories
type: item
description: Controlling a quadcopter is inherently challenging due to its nonlinear dynamics and susceptibility to external disturbances such as wind gusts and sensor noise. This paper explores the use of Model Predictive Control (MPC) to tackle these challenges. The goal is to create a robust control system capable of stabilizing and directing a quadcopter along a specified trajectory, even when faced with disturbances. The next step derives the Linear Quadratic Regulator (LQR), which is used to stabilize the quadcopter. The research involves creating a detailed mathematical model of the quadcopter's dynamics, followed by the design and implementation of LQR and MPC. Through extensive simulations, the effectiveness of the MPC approach is validated, demonstrating its ability to maintain stability and achieve precise control under various conditions. This study underscores the potential of MPC as a powerful control strategy for UAVs, offering significant advantages for real-world applications where traditional control methods may fall short. The LQR controller balances the performance of the drone and the energy it consumes by specifying the weighting matrix of performance cost Q and control cost R to calculate an optimized controller. MPC provides a robust and effective control strategy for quadcopters, offering improved performance and reliability. Its ability to handle nonlinear dynamics, manage constraints, and optimize control actions makes it an essential tool for advanced aerial vehicle control.

تأثير إضافة حبيبات الفونولايت والكاولين على ثابت العزل الكهربي ومعامل التوهين الإشعاعي لمادة مركبة مقوّاة بالألياف
type: item
description: في هذا البحث تمت دراسة ثابت العزل الكهربي ومعامل التوهين الخطي والكتلي لثلاث عينات من مادة مركبة مقوّاة بالألياف ذات أساس بوليمري. تم إعداد العينات باستعمال طريقة الرّصّ اليدوي للطبقات واحتوت جميعها على نسبة وزنية ثابتة من ألياف الزجاج العشوائية الترتيب. العينة الأولى اعتُبرت كعينة مرجعية وتم تحضيرها باستعمال الألياف كمادةِ تقوية والبوليمر كمادةٍ أساس دون أي إضافات أخرى، بالنسبة للعينتين الثانية والثالثة فتم تحضيرهما بإضافة حبيبات من مادتي الكاولين والفونولايت (بحجم حبيبي يتراوح ما بين 75 إلى 125 ميكروميتر وبنسبة وزنية مقدارها 10%) إلى المادة البوليميرية على الترتيب. لجميع العينات تم حساب ثابت العزل الكهربي، ومعامل التوهين الإشعاعي لأشعة جاما الناتجة عن نظير السيزيوم المشع Cs 137 عند الطاقة 662 كيلو إلكترون-فولت، وأظهرت النتائج أن إضافة حبيبات الفونولايت والكاولين إلى المادة المركبة كان لها تأثيرٌ واضحٌ على قيم معامل التوهين الإشعاعي، فمثلاً ازداد معامل التوهين الخطي والكتلي بحوالي 30% في العينة المحتوية على حبيبات الفونولايت، أمّا ثابت العزل الكهربي فكان تأثُّرُه محدوداً. خَلُصت الدراسة إلى أن إضافة حبيبات بعض المواد السيراميكية الطبيعية والمتوفرة محلياً أثناء عملية تصنيع المواد المركبة المقوّاة بالألياف يؤثر في خواصها الفيزيائية ويؤدي إلى تحسين بعضها وبشكلٍ ملحوظ ما يجعلها أكثر ملائمة للعديد من التطبيقات الواسعة التي تمتاز بها هذه المواد.

Optimal Power Flow and Contingency Analysis with Security Considerations Using Jaya Optimization Algorithm
type: item
description: Optimal power flow (OPF) is one of the fundamental tasks in modern complex electric grid operation. Its objective is to improve the economic and secure coordination on electrical networks based on pre-defined constraints. Combined with a complex operational network and higher demand patterns at times of day / week, it is clear that OPF solutions need to be accurately designed. This accuracy is crucial in order to increase stability across networks over time which in turn will reduce future operational risk. While modern grids increasingly integrate renewables, this work focuses on conventional OPF to establish Jaya’s core efficacy for contingency management, providing a foundation for future renewable integration. This paper presents a computationally distinct application of the Jaya optimization algorithm for solving OPF problem taking into account contingency analysis and security assessment. It then proceeds to carry out an optimization using the Jaya algorithm, a cost-effective and parameter-less-dependent technique for system-wide minimization of operational costs with adherence constraints imposed on online security and stability. The suggested approach integrates contingency analysis into risk assessment in order to assess critical vulnerabilities of networks and determine how potential failures propagate. Results of the simulation prove that Jaya algorithm outperforms GA and PSO in optimization. The proposed method not only increases the security level of OPF but it is also human-friendly rather than computationally expensive, making it an appropriate solution for real-time application of OPF schemes.

A Comparison between Relational Databases and Semantic Web Ontology in Web Application
type: item
description: This project compares the Relational Database model with the Semantic Web Ontology model through an educational web application serving academic levels in Libya from primary to secondary school. The application illustrates key differences in data storage and retrieval between the two models. Developed using software engineering principles, the system emphasizes flexibility, scalability, reliability, and usability. It manages educational entities—students, teachers, curricula, institutions, and their locations—by efficiently representing them and their relationships in both models. Practical comparisons showed that the Semantic Web Ontology offers superior flexibility and semantic representation, with faster search and reasoning capabilities that reveal new relationships. However, it needs improvements in security and reliability.

Comparative Study: Canny-LoG Edge Detection with Canny-Prewitt Edge Detection by using Huffman Encoding of Image Steganography For Grayscale Images
type: item
description: The security of data flow is a major concern for the public network that is the Internet. A data transmission security method called steganography conceals the message within a media container, like an image. Undoubtedly, the media cannot carry so much embedded data. Because the image edge area can withstand pixel value fluctuations better than the center, the edge area is used to accommodate additional message bits. In this study, the hybrid Canny-Log detector was compared with hybrid Canny-Prewitt detector by compress a grayscale images using the Huffman algorithm and hid them in the edges of other color images. This combined two-detector method provides a larger edge area for increased message payload while keeping hidden images unnoticeable. The hybrid Canny-LoG detector was achieved better results in embedding capacity (EC) in terms of the number of pixels available for hiding. Additionally, good results were obtained in quality metrics, such as the mean squared error (MSE) and peak signal-to-noise ratio (PSNR) for the stego image.

Experimental Study on soil stabilized with Geotextile under a Square Footing
type: item
description: By utilising laboratory model footing tests, the performance of foundations on clay soil reinforced with geotextile was examined. The steel plate used to make the square model footing had dimensions of 250 mm by 250 mm. The length of the reinforcement layers, the type of geotextile, and the top layer spacing were among the parameters examined in this study. According to the test findings, adding reinforcement could greatly increase the soil's bearing capacity and lessen footing settlement. The increase in BCR values varied depending on the type of geotextile, its position and how it dealt with the soil. BCR increases as u/B increases until it reaches a certain point where it decreases. The maximum improvement is achieved at u/B=0.67 for both types, this improvement varying depending on the length of the geotextile. The values of L/B that achieve a higher BCR is 8 for woven and nonwoven. The save length ratio that produce positive effect in all position is L/B=6.67. how-ever, in practice, nonwoven can achieve excellent performance with less reinforcement than woven.

Impact of Temperature and Solar Radiation on Photovoltaic Cell Efficiency: A Simulation Study Using MATLAB
type: item
description: This research targets studying the impact of temperature and solar radiation on two types of photovoltaic cells: monocrystalline and polycrystalline. This paper examines, through the use of MATLAB simulation, the variation in these environmental factors for significant parameters such as efficiency, power output, and voltage characteristics in order to deduce the superior performance type under high-temperature conditions. This was simulated for temperature and solar radiation variations from 25°C to 65°C, in 10°C steps, and 200 W/m² to 1000 W/m², in 200 W/m² steps, respectively. For both types of cells, constants, variables, and specifications were programmed into MATLAB, while iterative loops calculated the behavior of the cells under these conditions. Results have been presented as performance curves and graphs that relate temperature and solar radiation with the performance of photovoltaic cells. From the results, it can be obtained that monocrystalline cells are more efficient in the test conditions described because of their being less affected by temperature rises compared to the polycrystalline ones. The investigation clearly shows how the choice of different photovoltaic technologies must take into consideration meteorological factors, especially for zones with high temperatures or variable radiation.

Safety Culture in Context: Macro and Micro Level Factors Affecting its Perception and Implementation: A Qualitative Inquiry
type: item
description: Safety culture assessment is an essential tool of organizational safety and has become mandatory in the aviation industry. A positive safety culture is a key for sustaining optimal safety performance in organizational safety. Most safety culture assessment tools are based on studies conducted in developed countries. However, safety culture assessment in developing countries, such as Arab countries is rarely examined in the aviation context. Semi-structured interviews with 14 technicians and managers in an aircraft maintenance organization based in an airport in an Arab country were conducted. These interviews discussed several topics related to occupational health and safety and safety management in aviation. The interview questions were designed based on a comprehensive examination of previous research on safety culture. The data obtained from the interview transcripts were categorized, resulting in a data structure that employed participants' quotes as primary codes and ultimately leading to the identification of three overall categories: Management commitment to safety, organizational safety practices, and role of social relationships. This study draws special attention to the influence of micro level internal factors of management commitment and organizational safety practices, and macro level external factors of the role of social relationships on the successful implementation of safety culture. Understanding the elements explored in this study offers a useful tool for distinguishing between various contextual elements and the level at which they operate. This could enable more effective management of these factors to improve the potential implementation of effective safety management.

Effect of Kaolin and Phonolite Particulates Addition on Hardness and Abrasive Wear Behavior of Glass−Fiber Composites
type: item
description: The aim of this experimental investigation is to study the hardness properties and abrasive wear behavior of glass fiber reinforced polymer (GFRP) composites modified with kaolin and phonolite particles as natural fillers. Three composites were fabricated by hand lay-up method using chopped glass fibers as reinforcement agent and unsaturated polyester resin as a matrix material. The first composite was prepared without any particulate additions to serve as a reference; the other two composites were prepared by incorporating the kaolin and phonolite particles at weight percentage of 10% in the polyester resin, respectively. Brinell hardness test was conducted to determine the hardness values of the composites, and the abrasive wear performance was evaluated using two-body abrasive wear test. Experimental results revealed that the addition of kaolin and phonolite particles improved both the wear resistance and hardness of the studied composites; nevertheless, the significant improvements were observed with phonolite-filled composite, the hardness and wear resistance of this composite were increased by 69% and 24.3%, respectively. The findings of this study indicate that the lack of abrasive wear resistance and hardness properties of GFRP composite which limit their use as wear-resistant materials can be improved or overcome by selecting and using of proper particulate fillers.

An Improved Round Robin Scheduling Algorithm For Enhancing CPU Utilization
type: item
description: CPU scheduling is the first goal and most important section of any operating system. CPU Scheduling algorithms are the methods or strategies which help scheduler to choose process in the ready queue. One of those strategies is Round Robin scheduling algorithm, a big challenge in this algorithm is how to adapt dynamic time quantum to be suitable for all of processes allocated in the ready queue, thus achieve making the best use of CPU. In this paper, a model was built in which a dynamic time quantum calculated by using average and standard deviation formula executed first, then use slice time to perform the first cycle and next cycle until the ready queue becomes empty. By applying this idea, the average turnaround time, waiting time could be minimized and the throughput of the CPU could be maximized and compare the proposal algorithm with three modifications of Round Robin algorithm which modified in recent years. a pre-modified round robin algorithm (DevRR) was modified, a model standard deviation round robin algorithm (SDRR) was developed, where the slice time using statistical measures was calculated and a simulation with Java Eclipse Version 2021-12 (4.22.0) and JDK operating environment (16.0.1) was built, to see whether the experimental results meet my requirements or not? And our modified algorithm using three scheduling criteria was implemented and evaluated, where were the average waiting time, the average turnaround time, and the throughput rate.

Investigation of the Switching States in the Asymmetrical Hybrid Cascaded Multilevel Inverter
type: item
description: Cascaded multilevel inverter with unequal DC sources shows better performance in terms of the number of voltage steps at the output voltage than with equal DC sources, since the number of steps is higher when using unequal DC sources. Therefore, the output voltage waveform is improved and become closer to the sine wave. This in turn will reduce the harmonic content in the output waves. However, obtaining a separate DC source in every single cell in the inverter is difficult and costly, especially these sources are not equal (have different values) according to the used voltage ratio. Thus, hybrid cascaded multilevel inverter could offer a good solution, by using only one DC source and replacing the other sources with capacitors. However, a key challenging of this transformation is regulating the voltage of these capacitors at the specified values. This paper examines the significance of switching states redundancies of the voltage ratios on the capacitors balancing. Hence, a three-cell hybrid cascaded multilevel inverter with different voltage ratios has been modeled and simulated.
