    RFID-Based Gate Access Control System with PIN Entry
    (International Conference on Electrical Engineering Applications (ICEEA'2020), Department of Electrical Engineering, Ahmadu Bello University, Zaria, Kaduna State, Nigeria., 2021) Amusan, A.A; Ogidan, O; Nwauwa, Divine-Reward; Otuya, H
    Institutions, with a considerable number of staffs, need to record employee attendance, and also monitor and limit security breaches in the system. The manual process of performing the data logging for employee attendance is inconvenient and time-wasting. Hence, in this work, an automatic access control system and data logging for an institution gate barrier is developed using Radio Frequency Identification (RIFD) Technology. This system is unique because it combines RFID with Personal Identification Number (PIN) entry for enhanced security. The developed system grants access to authorized users as well as logs the user’s details into MySQL data base and eventually a webpage for security administration. Reliability assessment performed gave a reliability of 98% at the gate entry point and 97% at the exit point. The system is convenient, reliable, with components readily available. Possible applications include personal premises, military zone, and premises of government or organisation where high level of security is required.

    Smart Irrigation System: A Water and Power Management Approach
    (IEEE, 2022) Edodi,M; Ogidan, O; Amusan, A.A
    Energy, water, and agriculture together form a formidable synergy which when properly utilized can achieve national growth and development. Cost effective solar powered irrigation systems can be the answer for all energy and fuel crisis. In this work, a smart irrigation system that considers the available water and solar energy power to determine the performance of its irrigation process is developed. The system adopted solar power such that it could be deployed in places with inadequate or no grid power while providing a means of monitoring the available solar/battery power as well as the water available in reservoir over the Internet on a Blynk user-friendly application. Experiments carried out at 7 am to 8 am, 1 pm to 2 pm, 3 pm to 4 pm and 7 pm to 8 pm reveal the dependence of the irrigation system on optimal utilization of the two essential parameters of water and power for a smooth operation of a smart irrigation system. During this time, system operation is simultaneously monitored in real-time via a user-friendly interface on an Android mobile device. The adopted approach in this paper provides a convenient way of remote monitoring of solar energy power and water for an irrigation system and enhances effective use of resources (water and power). Optimal usage of resources prolongs lifespan of irrigation facilities such as solar battery and water pumps while making adequate water available for irrigation to achieve bumper crop yield.

    An Automatic Railway Level Crossing System with Crack Detection
    (IEEE, 2022) Amusan, AA; Adebakin, Y
    Railway system is a kind of transportation where passengers and goods are transported on wheeled vehicles running on rails located on tracks. This form of transportation is usually inexpensive, secure, and often the most convenient. In areas with frequent use of railway transport system, there is need to limit the accidents at the level crossing, mitigate the falling of trains on the rail due to cracks and create an excellent feedback system. The manual management of the system is inconvenient, time wasting and prone to sudden accidents. Hence in this work, an automatic railway system which includes automatic level crossing and crack detection system with an excellent feedback process is developed using ultrasonic sensors and microcontrollers for control. The system is unique because it uses ultrasonic sensors for maximum performance. The developed system detects cracks on the rail, automatically controls the level crossing to avoid collision and send all possible feedbacks to a remote station using the SIM module. The reliability assessment of the system gave 93.3%. The system is reliable, efficient, and convenient and it is recommended for areas where rail transport systems are demanding.

    Industrial Training as an Integral of Engineering and Technology Education: Issues and Prospects
    (2002-09) Falade, F.
    In this paper, the philosophy of engineering and technology education curricula in Nigerian Universities is presented. The paper notes that in formulating the curricula, industrial training is incorporated into the programme to ensure that students are given the much-needed on-job-experience during their course of study in the Universities, to make them better prepared for the challenges in the industry thus making them more relevant in the industry after graduation. An assessment is made of how well the curricula have been able to meet the needs of the industry taking cognisance of all the obstacles militating against the effective performance of Faculties of Engineering and Technology in the Universities and the problems in the industrial sector. It is suggested that to make progress technologically, there is need to provide an enabling environment that guarantees adequate facilities and funding engineering and technology education in the universities and a corresponding expansion in the industry.

    Quality Control In Road Construction And Maintenance:
    (2013-05-09) Falade, F.
    Roads are built to provide safe passage of vehicles. They must be properly designed and constructed. After construction, roads deteriorate with age as a result of use and therefore, they need to be maintained to ensure that the objective of safety, strength and durability are met. The rate at which roads deteriorate in service depends on the quality of materials used, workmanship standard and the quality of supervision during the road construction. If roads are not maintained, functional defects will degenerate to structural defects that will require rehabilitation or reconstruction. The objective of quality control in road construction and maintenance is to achieve a well built pavement that conforms to the required horizontal and vertical profiles, design thicknesses of different courses (earthwork, sub-base, base and surface) and stipulated standards of riding quality. At each stage of construction or maintenance operations, quality control is required during the preliminary design, source acceptance, job-mix and construction. Relevant quality control tests should be carried out on construction materials. The plants and equipment must be of good quality and must be consistent with the type of job to be done. Effective supervision of construction or maintenance works as well as plants and equipment by qualified engineers is the key to the achievement of the overall objective of quality control. Engineers are to ensure that contractors comply with all the project specifications. Effective quality control leads to reduction in the cost of construction and maintenance, lowers cost of vehicles operation, transportation and maintenance. It is recommended that the option of preventive maintenance of our roads rather than reactive maintenance should be urgently embraced because preventive maintenance results in prolonged service life of roads and significant savings for the government.
