DESIGN AND IMPLEMENTATION

This project focuses on the design and implementation of an automatic changeover system integrated with contactors and an Automatic Voltage Regulator (AVR) for efficient management of a home solar power system. The system is designed to automatically transfer load supply between the solar inverter, utility grid, and generator in the event of power failure or voltage instability, ensuring uninterrupted power delivery to essential household appliances. The control unit employs electromechanical contactors to achieve seamless source selection, while an AVR maintains stable voltage output to prevent damage to sensitive equipment. A timer/delay relay is incorporated to coordinate the switching process, minimize transient currents, and delay the operation of the alarm siren to prevent false triggers during short interruptions. The project also integrates protective circuit breakers to safeguard the system from overloads and short circuits, improving safety and reliability. The overall design emphasizes efficiency, automation, and simplicity, eliminating the need for manual intervention during power transitions. Testing and evaluation were carried out under various load conditions to verify performance. Results confirmed that the system achieves reliable source transfer, stable voltage regulation, and reduced downtime during source changeovers. The project demonstrates a practical and cost-effective solution for domestic solar power management, promoting energy efficiency and dependable power supply in areas with unstable grid systems.

The use of induction motor in various facets of engineering, manufacturing and the production sector to power various equipment have gained stability and thereby creating huge starting current which in turn contributes to the unbalanced loading of network giving rise to high energy and economic loss. This research work, therefore, seeks to reduce the starting current of the connected single-phase induction motor. A smooth and soft start is employed in a single-phase induction motor to eliminate the surge in current and electromagnetic torque during starting. The surge in current and torque are eliminated using soft starter at the time of starting. The soft starter also eliminates the unwanted effect in electric cables and the distribution network. This project work provides an in-depth description of the sentimental and smooth start to an induction motor. The smooth start of the motor is predicted by the firing angle of the TRIAC circuit. The firing angle is delayed during starting and the delay angle reduces as the motor picks up to speed. This proposed technique provided reduced voltage at the starting and the rated voltage when themotor is up to speed. By using soft starter, the performance and efficiency of the induction motor is improved and it also improves the load torque characteristics. This project consists of 6anti-parallel SCR connected in each series with an induction motor to the main supply, where into each phase. When starting the firing angle is heavily delayed by receiving delayed triggering pulses. The supplied voltage is gradually increased, and the torque also in same manner. By this process the inrush current is drastically reduced, making the motor start smoothly. The induction motor of0.56KW, frequency of 50Hz, maximum voltage 230V, receives little or no surge using the soft starter device. The start up ramp is about 4s to 7s, depending on the power of the induction motor. The firing angle is gradually decreased from 80˚ by interval of 20˚ until 0˚ max of the full half

Waste management in Edo State suffers from poor communication, irregular service delivery, and weak accountability due to manual record-keeping and fragmented reporting systems. This study developed a web-based Customer Relationship Management (CRM) platform to improve communication, transparency, and citizen participation in waste management. Using the Waterfall methodology, data were collected through interviews and literature review, guiding the design and implementation of the system with ASP.NET Core MVC, C#, Razor Pages, Tailwind CSS, and Microsoft SQL Server. The platform includes a customer interface for registration, request tracking, real-time chat, and announcements, and a waste manager interface for zone management, complaint resolution, and information sharing. Security measures such as Argon2 password hashing and role-based access control were implemented. Testing confirmed full functionality and reliability. The system enhances service delivery bycentralizing communication, standardizing complaint tracking, and promoting citizenengagement, offering a scalable model for technology-drivenwaste management across Edo State.

The growing incidence of zoonotic diseases and other health risks underscores the pressing necessity for integrated surveillance systems that connect the sectors of human, animal, and environmental health.

During the period of rapid spread of the corona virus infection, a large number of infected were
quarantined and otherwise isolated from the general populace. Face to face access to such people
was risky and difficult. Even medical personnel had to take stringent and inconvenient measures
to safeguard themselves, before they could meet physically with such patients. Arising from this,
the aim of this work is to design and construct a telepresence robot that will help to monitor, and
communicate with an isolated person.
The proposed system makes use of a mobile platform driven by four electric motors, with each
driving wheels for precise navigation control. The motors are controlled by an L298N motor
driver. The system also makes use of central microcontroller with WIFI capabilities to establish
connection with a smart phone using the Adafruit IoT (Internet of Things) interface. It also has a
12V lead acid battery for supplying power. The power supplied by this battery is regulated and
stepped down to 5V by an Lm7805 voltage regulator and this voltage regulator supplies power
directly to the micro-controller and the motor driver (or controller)
The system performed as required. The robot successfully connects to the internet and responds to
commands given through the IoT platform. Motors responded correctly to commands, rotated in
the specified direction, and at the desired speed. The motor control system is functioning properly,
and the robot can move as intended. The robot can transmit a clear and stable live video feed with
minimal lag. However, when the internet connection is poor, the video feed becomes blurry,
pixelated, or experiences frequent interruptions
