    Design and Optimization of a Hybrid Solar Photovoltaic/Diesel Energy System Using HOMER Software
    (2025-06-23) Abdullah Ammar; Hamza Aker; Hussam Ezzat
    Project’s Abstract: Energy access in Palestine faces serious challenges due to political instability, high dependency on imported electricity, and limited local energy resources. The West Bank has an abundance of solar potential, but it is not yet entirely utilized. In order to provide a dependable, economical, and sustainable energy solution, this study explores the design and optimization of a hybrid solar photovoltaic (SPV) and diesel generator (DG) system for the Palestinian Museum in Ramallah. The objective is to use HOMER and PVsyst software to assess the hybrid system's technical, financial, and environmental feasibility. Based on real energy consumption data, sun irradiance, and system component specifications, these tools made simulation and performance analysis possible. In order to model a 230 kWp grid-connected PV system, 576 modules and inverters with a combined output of 220 kWac were used. The diesel generator was used in times of solar shortages because the PV system was not built with battery storage. It was also utilized when the grid was unavailable. The system can generate 364,653 kWh yearly, according to PVsyst results, with a performance ratio of 80.84%. Strong economic viability is demonstrated by the system's low levelized cost of energy (LCOE) of 0.0307 USD/kWh, 3.2-year payback period, and internal rate of return of 31.33%. In terms of the environment, the system lowers CO₂ emissions by about 394.7 tons per year. These results were confirmed by HOMER simulations, which found that the PV/Grid system had the lowest COE at 0.0835 USD/kWh, while the PV/40 kW DG hybrid system provided reduced emissions and increased reliability with an 83% solar energy ratio compared to diesel-only options. A renewable energy fraction of 84.8% was achieved by the hybrid arrangement, highlighting the financial and environmental benefits of greater solar integration. By offering an affordable and appropriate hybrid renewable system model, this study helps close the energy gaps in Palestine and promotes resilience, energy independence, and long-term sustainability in areas challenged by conflict and a lack of energy. Keywords: Solar photovoltaic, Hybrid system, HOMER, Solar Photo-Voltaic, Diesel Generator, Solar/Diesel hybrid energy, Palestine.

    Abestract: Integrated Low-cost Electrospinning Device for Nanofibrous Scaffold Fabrication this project can help educational institutions to have such electrospinning system with ultra-low cost comparing with readymade systems in the market , However, it is difficult to gathering nanofibers with simple design and reasonable price device. This study presents a cost effective and safe electrospinning system with similar capabilities to standard electrospinning device. As standard current electrospinning system consists of three constructed parts, a hand-constructed electrical power supply to provide a high voltage source direct current (DC), a low cost three-dimensional (3D) printed syringe pump and handmade collectors. The device components are entirely constructed off-theshelf components, and structural elements are 3D printer. The electrospinning process was carried out using PLA materials. The general parameters in the production process are resolution of the spraying rate micro litter/min and the power supply provides electricity in kilovolt

    (2025-02-26) “Mohammad Tariq” Fares; Yazan Mousa (11924269); Mohammad Allan (11925611)
    Abstract In the ever-evolving field of mechatronics engineering, the application of Computer Numerical Control (CNC) technology has become a pivotal aspect of modern industrial manufacturing. This project focuses on the development and implementation of a CNC four-axis milling machine with five degrees of freedom, designed specifically for the processing of soft materials such as plastics, wood, aluminum, and copper. The primary aim is to enhance precision, reduce time and effort, and lower costs compared to traditional three-axis CNC machines. By integrating an additional axis, this innovative technology allows for the fabrication of more complex and precise parts, broadening the scope of applications in various industrial sectors including automotive, aerospace, electronics, and construction. The project involves a comprehensive study of the mechanical and electronic design elements essential for the construction of the CNC milling machine. This includes the development of a robust structure capable of withstanding high precision operations, the integration of advanced stepper motors and control systems, and the implementation of G-code programming for precise tool path generation. A detailed analysis of the selection and testing of suitable materials ensures that the machine can efficiently handle a variety of soft materials, maintaining high accuracy and quality in production. Furthermore, the project explores the historical evolution of CNC technology, highlighting the advancements that have led to the current state of the art in four-axis CNC machining. This historical context provides a foundation for understanding the significance and potential of the developed machine. The study also delves into the cost implications of CNC technology, emphasizing the cost-effectiveness of the designed machine in comparison to high-end commercial CNC machines. This aspect is particularly crucial for small and medium-sized enterprises looking to adopt advanced manufacturing technologies without incurring prohibitive costs. The control design aspect of the project is meticulously detailed, focusing on the core control components, the integration of the rotary axis, and the development of a user-friendly interface for machine operation. The G-code programming, a critical component for CNC operation, is thoroughly explored to ensure seamless and accurate machining processes. The project also addresses the challenges associated with machining different types of soft materials, providing solutions to optimize the milling process and enhance the machine’s versatility. The culmination of this research and development effort is a cost-effective, efficient, and versatile CNC milling machine that meets the demands of modern manufacturing. It is designed to offer increased precision, reduced production time, and significant cost savings, making it an ideal solution for various industrial applications. The project not only contributes to the field of mechatronics engineering but also provides a practical tool for enhancing manufacturing capabilities, improving product quality, and increasing operational efficiency in competitive and innovative manufacturing environments.

    Pellet 3D printer
    (2024-09-26) Osama Muhammad Daoud; Sabeeh Omar Daher; Abdullah Wael Fakhry Ass
    3D printers will undoubtedly continue to increase the capabilities of small- and mid-sized manufacturers well into the future. The most exciting advances are yet to come. And the biggest winners out there will be the manufacturers with the vision to foresee the possibilities these revolutionary machines can unlock. This report focuses on the design and development of a Pellet 3D printer Starting from the mechanical design, then the electric and controller selection, followed by the software, programing. Throughout this project, we delved into various 3D printing methodologies, focusing on Fused Deposition Modeling (FDM). This falls within the realm of additive manufacturing (AM), where filament, such as PLA material, serves as the primary material. FDM employs a three-mechanism movement, and for our project, we utilized the Creality Ender 3 printer, which operates on a conventional 3-axes CNC mechanism. Then we talked about plastic extrusion, a process involving the melting and shaping of raw plastic. Subsequently, we embarked on the task of designing a novel printer head using Creo Parametric. This included creating essential components through 3D printing, assembly of the extruder, and its installation onto the printer, replacing the original head. The final step involved calibrating the printer, this step is the most important step where we will make the controller deal with the mass of pellets instead of the length of filaments, setting the stage for its subsequent use in the examination of diverse material samples.
