Item Automation in construction materials handling: the case study in north central Nigeria(West Africa Built Environment Research (WABER), 2019-08-07) Alumbugu, Polycarp Olaku, Winston W M Shakantu , Tsado Abel John & Adeniran Wasiu Ola-AwoAutomation in construction material handling system is a method of utilising material handling equipment. It could be the basis of cost reduction or wasteful expenses if not efficiently planned. However, there is limited understanding of construction material handling process utilised by the manufacturing industry in Nigeria. Thus, the aim of this study is to evaluate the efficiency of automation in material handling by the manufacturing industry in North Central Nigeria. A quantitative method and case study research approach was adopted, six construction material manufactured and distributed within the North-central region of Nigeria were selected for this study. A purposive sampling method was used for the selection of the ten construction material manufacturing companies used in the research. The study employed non -participant structured observation and measurement template for the data collection. The material handling processes observed includes, order picking method, material handling equipment, storage equipment, loading and offloading equipment. The descriptive method of data analysis was employed using percentage and results presented in a form of bar charts and interpreted directly. The study concluded low utilisation of automation in the combined processes of order picking, handling, storage, loading and offloading. But used more manual labour that involved multiple handling. This low adoption of automation in material handling by the manufacturing industry leads to inefficiency. This in turn have a negative influence such as poor management, low throughput, prone to error, long lead time and high labour cost. These have the implication of increasing construction cost and cause project delay. This study was conducted using observations which is one of the limitations of this study.Item Refinement of Triple Accelerated Over Relaxation (RTAOR) Method for Solution of Linear System(Nigeria Mathematical Sciences (NMS), 2021-04-21) Khaddejah James Audu; Yahaya, Y. A.; Adeboye, K. R; Abubakar, U. YIn this paper, a Refinement of Extended Accelerated Over-Relaxation (REAOR) iterative method for solving linear systems is presented. The method is designed to solve problems of partial differential equations that results into linear systems having coefficient matrices such as weak irreducible diagonally dominant matrix and 𝐿−matrix (or 𝑀−matrix). Sufficient criterion for convergence are examined and few numerical illustrations are considered to ascertain efficiency of the new method. Outcome of the numerical results reveals that the REAOR iterative method is more efficient when compared with Extended Accelerated Over-Relaxation iterative method in terms of computational time, level of accuracy and required number of iterations for convergenceItem Analysis of the technical efficiency in maize and sorghum production in Kaduna State, Nigeria using the parametric and non-parametric models(Nigerian Association of Agricultural Economists (NAAE), 2018) Ogaji, A., Tanko, L., Nmadu, J.N. and Olaleye, R.S.ABSTRACT The study analyzed the technical efficiency of maize and sorghum production in Kaduna State using the parametric and non-parametric models. Data were collected from primary sources and was obtained using the multistage random sampling technique. A total of 303 respondents were sampled. Analytical tools employed were descriptive statistics (means and percentages), Stochastics frontier model and data envelopment analysis. Results showed that 65% of the respondents were between the ages of 31-50, 86.8% were males and 74.3% were married. Result also showed a mean technical efficiency of 0.72 and 0.86 for SFA and DEA Models respectively. It was recommended that both models should be used in determining efficiency giving the importance of accurate production efficiency estimates in policy decision making.Item Building a Modern Land Administration System in Nigeria(School of Environmental Technology Federal University of Technology Main Campus, Gidan Kwano, Minna, Niger State, Nigeria, 2016) Kemiki Olurotimi Adebowale; Ayoola Adeyosoye Babatunde; Kuma Shien Stephen; Ojetunde Ismail; Fabunmi Foluke OlanikeLand administration is a significant framework for the management of any nation’s pool of resources and has remained one of the most chatted discourses among urban issues in many developing countries. This paper examines the issues in land administration in Nigeria and other developing countries, looking at the various administrative and legal frameworks in place for an efficient land delivery system. The land administration system in Nigeria is plaque by challenges spanning from policy, institutional and legal frameworks to technical and operational issues which have direct impact on implementation. These challenges emanated from some of the import ideologies that adjustments could not be made upon. The study recommends the reform of policies and the creation of a local integrated land administration system model (LAS) that will accommodate our country peculiarities. Also the development and sustenance of an ICT based professionals and infrastructure that will enhance efficiency in the land information system.
