This paper aims to maximize photovoltaic (PV) energy yield by using time based non optical a dual-axis solar PV tracking system. System’s design, simulation, prototype implementation, and performance evaluation will be presented. The dual-axis system under investigation, in contrast to fixed or single-axis tracking systems, allows for optimal solar incidence throughout the day and throughout the seasons by adjusting the orientation of the solar panels along the east-west and north-south...
Photovoltaic (PV) water pumping systems have emerged as a reliable and environmentally sustainable solution for agricultural irrigation and water supply in remote regions. However, the performance of PV modules in arid and desert environments is significantly affected by elevated cell temperatures caused by intense solar radiation and high ambient temperatures. Although various cooling techniques have been proposed, many require additional energy consumption or impractical water use. This...
The luxury yacht industry is undergoing a transformative shift toward sustainability, with increasing emphasis on reducing carbon footprints and optimizing energy consumption in onboard systems, particularly in the hotel sector. This study presents a novel application of the Nonlinear Autoregressive (NAR) neural network for time series forecasting of energy usage and generation aboard luxury yachts. Leveraging real-world datasets from BlueAI, the study focuses on three critical energy...
This paper investigates the impact of integrating a 5 MW photovoltaic (PV) distributed generation unit into a 66 kV sub-transmission network in western Libya. The study aims to improve voltage profile and reduce active power losses through the proper integration of distributed PV generation. The electrical network was modeled using NEPLAN software based on real grid data obtained from the General Electricity Company of Libya (GECOL), while the PV system was designed and simulated using...

This study investigates a finite element analysis (FEA) of a dissimilar welded assembly consisting of a pure copper tube (C11000) and a brass flange, joined via the tungsten inert gas (TIG) welding process using ERCuSn-A filler metal. Numerical simulations were conducted using SolidWorks Simulation to evaluate the thermo-mechanical response of the joint under specific operating conditions. The research encompasses a transient thermal analysis of the welding process, followed by a static...
Deep drawing is one of the primary sheet metal forming processes used to manufacture three-dimensional components for various industries such as automotive and household appliances. Among the major challenges associated with this process are maintaining uniform thickness distribution and reducing springback, due to their direct effect on the quality of the final product. This study aims to analyze the effect of gradually varying punch speed during the deep drawing process on thickness...
