The Nigerian Journal of Technology is based at the Faculty of Engineering, University of Nigeria, Nsukka and has been in existence for over 30 years. Any paper submitted to the journal should be an original thought-provoking review or appraisal of existing knowledge, collation of relevant data of interest or investigation and exploration of new fields in engineering, applied science and technology. The paper should cover any aspects of engineering education, planning, analysis (experimental, modelling and simulation), design and construction or performance evaluation of technological systems.
