Electronic prescription (e-prescribing) systems, which promise improved patient safety, increased productivity, and a reduction in pharmaceutical errors, have revolutionized the healthcare industry by replacing traditional paper-based prescriptions. By allowing medical professionals to electronically communicate prescriptions directly to pharmacies, e-prescribing lowers the risk of human error and unreadable handwriting. Research has demonstrated that this digital strategy improves workflow and patient care in addition to streamlining the prescription procedure (Baruah et al. 2020; Samad et al. 2021)

The device described in this study can be used in hospitals to verify prescriptions, maintain patient data, and protect patient privacy. In this study, patient databases are tracked using RFID tags and a web server. This method can prevent prescription drug abuse in addition to capturing precise and current information on patients' prescriptions. Real-time patient data can assist clinicians in reducing medication errors and provide the best care possible. In this paper, a medical mechanism that uses the modified grouping proof process is suggested in order to improve medication safety for inpatients. The medical staff could verify the authenticity and integrity of a group of Radio-Frequency Identification (RFID) tags that are embedded on inpatient bracelets and drug containers by using the grouping proof protocol. RFID authentication is the ideal option for automated patient medication systems since it requires mutual authentication between the medication server and the tag.

This project looks into the designing and installation of solar PV system to power some appliances in a five bedroom bungalow building. This is necessary because of unreliable power supply. Solar energy is a clean and endless source of power from the sun, unlike electricity from utility companies which can be limited and affect daily activities. In this project, we designed a solar PV system which consists of PV cells, charge controller, inverter, batteries.The size of the solar panels, battery capacity, and other components needed to run the appliances efficiently was calculated. Then testing of each part of the system was carried out to make sure it worked properly before putting it all together. The photovoltaic cells were used to capture sunlight and convert it into electricity. This electricity is then sent to the charge controller and then to the inverter which then charges the batteries. The stored charges in the batteries can be used to power our appliances even when the sun isn’t shining. The system is designed specifically for powering home equipment like fans, light bulbs, fans etc. The final system was tested in the University of Benin, Benin City, (6.3998° N, 5.6099° E). It was successfully used to power some home appliances like light bulb, fan. From the test, graphs of current (amps) against time (hrs) and power (watts) against time (hrs) were plotted it was then observed that at the earlier hours of the day, the current and likewise the power from the panel increases and it is maximum at 1:30pm. It begins to reduce from 2pm. This is due to the reduction of the irradiance of the sun. The weather becomes a bit cloudy and towards evening there is minimal sunlight resulting in lesser current. The more the sunlight, the higher the current and vice versa.This shows that solar power can be a reliable way to run home equipment, even in places with frequent power outages. Overall, the project demonstrates that solar energy has the potential to reduce reliance on traditional electricity from utility companies.

This project focuses on the design and implementation of a web-based public complaint management system for the Benin Electricity Distribution Company (BEDC), aimed at addressing critical inefficiencies in traditional grievance handling processes. The system provides a structured digital platform that enables customers to submit, track, and monitor complaints related to power services, including outages, billing disputes, meter issues, and service delays, while allowing administrators to efficiently manage, process, and resolve grievances in a transparent and timely manner. Through a user-friendly web interface accessible via standard browsers, the platform eliminates challenges associated with manual complaint systems, such as lost records, delayed responses, lack of accountability, and poor tracking capabilities that have historically undermined customer trust and organizational credibility.
The study employs a systematic approach involving the investigation of existing manual and basic digital complaint management systems at BEDC, the identification of their limitations, and the development of an enhanced web-based solution using modern technologies, including HTML, CSS, JavaScript, PHP, and MySQL. Key features include secure user authentication, real-time complaint submission and tracking, automated workflows for efficient complaint routing, comprehensive database management for record-keeping, and administrative dashboards for monitoring and analyzing complaint patterns. The system incorporates robust security measures and accessibility features to accommodate diverse user groups while ensuring data privacy and integrity. By implementing this solution, the project addresses recurring issues such as delayed responses, limited transparency, and inadequate feedback
mechanisms that discourage customers from reporting grievances. The findings contribute to improved customer satisfaction, enhanced organizational efficiency through data-driven decision-making, and the advancement of knowledge on ICT applications in public utility administration, providing a scalable model for digital transformation in similar service sectors across Nigeria and beyond.

The comprehensive study of high-frequency transmission lines, including stripline, microstripline, differential microstriplines and differential striplines configuration is ritical for advanced RF and microwave engineering education. Fundamentals of some transmission line phenomenon such as impedance matching, reflection coefficient and the effect of open and short circuits, relies greatly on practical hands-on experience alongside theoretical tools like the Smith chart. Furthermore, many academic institutions face challenges in providing laboratory systems that accurately represent high-frequency transmission line structures on common PCB substrates such as FR4. The absence of versatile and cost-effective experimental circuits limits students’ opportunities to explore and solve real-world transmission line problems, thereby hindering the development of essential engineering skills. This project aims to develop an integrated high-frequency transmission line experimentation systems for university laboratories, incorporating stripline, microstripline, differential microstriplines and differential striplines configuration on FR4 substrates. The system will facilitate direct measurement and analysis of transmission line behavior, enabling students to visualize various experiments, and investigate the proposed applications (e.g. open and short circuit effects, s-parameters, transmission line as a filter etc.) within a controlled environment. By linking theoretical concepts with practical experiments, specifically through the application of Smith chart and transmission line theory, this system will enhance RF engineering education, equipping students with the competence needed to address modern communication system challenges effectively.

The management of student complaints in many tertiary institutions relies on fragmented, manual processes that lead to inefficiencies, delayed resolutions, and a lack of transparency and accountability for course representatives and faculty administration. This project addresses this systemic challenge by designing and implementing a web-based Faculty Complaint Management System. The system provides a centralized platform featuring three distinct user roles (Administrator, Lecturer, Course Representative) and utilizes PHP, MySQL, and Bootstrap for development. Its core functionality includes secure, role-based access control, an intuitive interface for course representative complaint submission and real time status tracking, and robust administrative tools for user management and automated complaint routing based on lecturer assignments. The methodology involved a systematic approach from requirements analysis and UML- based design to implementation with best practices for data integrity and security, including password hashing and protection against common web vulnerabilities. Rigorous testing across multiple levels including unit, integration, system, and user acceptance testing validated the system's functional reliability and usability. The completed system successfully replaces the manual process, providing transparency, accountability, and efficiency through centralized tracking, activity logging, and statistical reporting capabilities. The solution contributes a validated, context-specific application of open-source technology to enhance administrative service delivery in higher education

The existing landscape of real-time communication often relies on traditional wire intercom systems which are characterized by high installation costs, complex wiring, and inherent flexibility, posing significant challenges for scalable deployment in dynamic environments. These limitations necessitate a modern, cost-effective, and easy-to-deploy solution that utilizes existing infrastructure. The primary aim of this project is to address this deficit by designing and implementing a functional, low-latency 4-channel Wi-Fi ( Wireless Fidelity) Local Area Network (LAN) based wireless intercom system capable of facilitating clear, full-duplex voice communication among multiple users.The system methodology centered on a decentralized, peer-to-peer architecture utilizing ESP32 microcontroller for its integrated Wi-Fi capabilities and dedicated I2S (Inter integrated sound ) digital audio interface. Audio quality was managed by pairing an INMP441 digital microphone a MAX98357A digital amplifier, eliminating analog noise and circuit complexity. Crucially, communication over the LAN was executed using the User Datagram Protocol (UDP) instead of Control Protocol (TCP). This deliberate choice minimized packet overhead and connection management, which is essential for ensuring the reliable, low-latency data transmission required for real-time conversation. Testing confirmed the successful two-way voice transmission between all intercom units, with the system consistently demonstrating an end-to-end latency below the critical 150ms threshold required for human-perceptible real-time conversation. In conclusion, the project successfully validated the technical feasibility of leveraging commodity Internet Of Things (IoT) hardware for sophisticated communication tasks. The resulting system is a significantly more scalable and cost-effective alternative to legacy wired intercoms, demonstrating a framework for future development in affordable, high performance wireless communication product
