DESIGN AND FABRICATION OF A HYBRID WIND TURBINE AND SOLAR POWER GENERATING SYSTEM FOR ELECTRICITY

Year of Publication
Publication Type
Abstract
The increasing global demand for clean and sustainable energy has intensified the need for innovative solutions that harness renewable resources. This project explores the design and implementation of hybrid electricity generation system that integrates wind turbines and solar photovoltaic (PV) panels. By combining these two complementary energy sources gives an efficient means of power generation, particularly in regions with variable weather conditions. The wind turbine component captures kinetic energy from wind currents, while the solar panels convert sunlight into electrical energy. Together, they form a synergistic system capable of reducing dependence on fossil fuels, minimizing environmental impact, and enhancing energy security. The project also examines key technical aspects such as system configuration, energy storage, power conversion, and grid integration. Through simulation and analysis, the study demonstrates the feasibility and benefits of hybrid renewable energy system in meeting electricity demands sustainably.

DESIGN AND FABRICATION OF AUTOMATED CAR PARK ACCESS CONTROL SYSTEM

Year of Publication
Publication Type
Abstract
Car park management in Nigeria is largely manual, inefficient, and insecure, often relying on handwritten tickets and rope-operated barriers. These methods, coupled with an unreliable power infrastructure, lead to significant congestion and safety risks. This project addresses these challenges through the design and fabrcation of a cost-effective, solar-powered, automated car park access control system. The system architecture is based on a Master/Slave configuration using two ESP32 microcontrollers that communicate via the ESP-NOW protocol. The Master ESP32 serves as the central "brain," handling RFID authentication and image capture via an ESP32 camera. Upon an access attempt, the system immediately captures the driver's image and validates the RFID tag against a local database stored on an SD card. This process creates a secure visual audit trail by logging all attempts (granted or denied) with a timestamp and the corresponding image. The Slave ESP32 manages the physical "muscle", controlling the barrier's geared motor and monitoring an ultrasonic sensor for vehicle safety

ANALYSES OF WAVE INDUCED STRUCTURAL LOADS ON MARINE VESSEL HULL

Year of Publication
Publication Type
Abstract
This study analyses wave induced structural loads on marine vessel hulls with emphasis on vessels operating in the Gulf of Guinea. Marine vessels experience highly variable sea states, and traditional analytical methods often struggle to capture nonlinear effects such as slamming, springing, and whipping. These limitations create uncertainties in predicting hull stress and deformation, especially for modern lightweight and fuelefficient ship designs. Existing literature highlights the need for regionspecific modeling due to limited hydrodynamic data available for West African waters. This research addresses this gap by applying advanced numerical simulation techniques Computational Fluid Dynamics (CFD) and the Finite Element Method (FEM) to model wave structure interaction under realistic wave conditions. The study uses seawater properties, mildsteel hull material characteristics, and wave parameters representative of the Gulf of Guinea. The CFD model generates pressure distributions on the hull surface for selected wave heights, while the FEM model evaluates the resulting stresses and deformations. The simulation procedure followed mesh generation, boundary condition specification, wave creation, pressure extraction, and structural analysis.
