Item Restricted The Impact of Transformational Leadership on Employee Performance: A Field Study in the Ministry of Sports in Saudi Arabia(University of Baltimore, 2024-12) Alanazi, Fahad; Naylor, Lorenda; Henderson, Lenneal; Michael, EleftheriosThis research evaluates the impact of transformational leadership on the performance of employees in the Ministry of Sports in Saudi Arabia. The main research question explores transformational leadership and its impact on employee performance in the Saudi Ministry of Sports. Three main components are assessed: 1) the impact of charismatic leadership practices, 2) the relationship between inspiring motivation and employee performance, and 3) the role of individual consideration in employee job performance. Overall, the research asks, "How does Saudi Arabia's Ministry of Sports practice transformational leadership, and how does it influence employee performance?" A quantitative approach is utilized, as it provides a practical approach to achieving the objectives of the study. The researcher conducted an online survey for each of the selected study participants. The data collected from the study was subjected to a T-test to assess complex differences between the responses given by the study participants and ANOVA analysis of variance to test the study hypotheses. The aim of the research is to fill a management gap and provide beneficial information to decision-makers on the best leadership style to adopt for maximum productivity. In addition, this study is a scholarly resource for people interested in studying transformational leadership in Saudi Arabia.29 0Item Restricted Design and Simulation of Different MPPT Algorithms of a Standalone PV System(Saudi Digital Library, 2023-08-07) Alanazi, Fahad; Elgendy, MohammedThis study delves into a standalone PV system tailored for a DC load, conducting a comprehensive contrast between solar energy and conventional generation methods. It addresses solar energy's relatively diminished efficiency due to temperature and irradiance factors. To enhance overall efficiency, the research employs an MPPT-equipped PV system with a DC-DC converter. Diverse MPPT algorithms, including conventional and variable Perturb and Observe methods, along with the Incremental Conductance algorithm, are exhaustively discussed, detailing their advantages and limitations. The investigation employs a vibrating feeder as the load, powered by a variable-speed shunt DC motor. A buck converter serves as the chosen DC-DC converter type. MATLAB simulations intricately illustrate the PV array, DC-DC converter, Perturb and Observe, Incremental Conductance algorithms, and the DC shunt motor, with comprehensive result analysis. Sensitivity analysis is applied to sample time and step size, revealing their influence on the system and DC motor speed. The thesis further examines limitations and discusses future work beyond its conclusion.30 0
