- ItemOpen AccessIndustrial 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.
- ItemOpen AccessQuality 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.
- ItemOpen AccessComputer-Aided Instruction in Electrical Engineering Education(2002-09-23) Okafor, F.N; Akinbulire, T.O; Awosope, C.OThis paper discusses the experiences of the authors in the application of computer aided instruction (CAI) to Electrical Engineering Education. Examples of some CAI tools developed by the authors are presented. Also discussed are problem associated with development and/or acquisition of the necessary tools for CAI in a developing country like Nigeria.
