No. 1 March, 2013 African Journal of Computing & ICT © 2013 Afr J Comp & ICT – All Rights Reserved - ISSN 2006-1781 www.ajocict.net Foreward The African Journal of Computing & ICT remains at the nexus of providing a platform for contributions to discourses, developments, growth and implementation of Computing and ICT initiatives by providing an avenue for scholars from the developing countries and other nations across the world to contribute to the solution paradigm through timely dissemination of research findings as well as new insights into how to identify and mitigate possible unintended consequences of ICTs. Published papers presented in this voume provide distinctive perspective on practical issues, opportunities and dimensions to the possibilities that ICTs offer the African Society and humanity at large. Of note are the increasing multi-disciplinary flavours now being demonstrated by authors collaborating to publish papers that reflect the beauty of synergistic academic and purpose-driven research. Obviously, these developments will drive growth and development in ICTs in Africa. This issue of the African Journal of Computing & ICTs contains journal articles with a variety of perspective on theoretical and practical research conducted by well-grounded scholars within the sphere of information technology and allied fields across the globe. While welcoming you to peruse this volume of the African Journal of Computing and ICTs, we encourage you to submit your manuscript for consideration in future issues of the Journal Have a fruitful reading Thank you Longe Olumide Babatope PhD Managing Editor Afr J Comp & ICTs vi Vol 6.

Asaolu Department of Systems Engineering University of Lagos Akoka, Lagos, Nigeria [email protected] ABSTRACT Gas flaring emissions constitute a threat to both terrestrial and aquatic life. This work establishes the viability of Neural Networks for forecasting concentrate volumes and is situated within Missing Data and Quality problems. A feed-forward Multi-Layer Perceptron (MLP) with 2 hidden layers (consisting of 200 nodes each) and a multiple output layer was developed using Matlab software. The six input nodes models Stack height, Temperature ratio, Flame length, Gas flow rate, Hydrogen Sulphide in solution gas and Combustion efficiency. The eight output nodes give the percentage volume ratio of emission concentrates. Data was collated from Nigerian Oil & Gas firms and the Federal Environmental Protection Agency. The neural network inputs and targets of the
