- 3. iii From the Editor’s Desk The Editorial Board of AZOJETE is happy to publish the eleventh volume of our Journal. This was made possible by the enormous contributions from our reviewers around the country and all over the World. This volume is a promise fulfilled as it continued to showcase articles from the fields of Agricultural and Biological Engineering, Civil Engineering, Computer Engineering and Electrical and Electronic Engineering. Other areas represented are Mechanical Engineering and Quantity Surveying. Contributors from all fields of Engineering, Science, Technology and Environment are hereby encouraged to submit their articles to the Journal as the Editorial Board has put in place a mechanism aimed at ensuring a speedy assessment of every paper that is submitted for publication. The AZOJETE is now available online in its website: www.azojete.com.ng. We encourage our Readers and Contributors to visit our website and read and download articles since our Journal is operating on Open Access. Our call for papers is out and available online. At the moment, articles are already being assessed for the next volume and we intend to bring out Volume 12 (2016) of AZOJETE before the end of the year. We wish to assure our numerous contributors of articles from all fields of Engineering, Technology and Environment that our Journal will soon be indexed in major Scientific Data bases. Finally, we would like to acknowledge the moral and financial assistance rendered to the Editorial Board by members of the Faculty Board of Engineering. Thank you. Dr. Ndubisi A. Aviara (Editor-In-Chief)
