Engineering Design and Mathematical Modelling

Professor Nnamdi Nwulu is researcher, educationist and engineer. He holds BSc and MSc degrees in Electrical & Electronic Engineering and a PhD degree in Electrical Engineering. He is currently an Associate Professor in the Department of Electrical & Electronic Engineering Science at the University of Johannesburg. He is also a Professional Engineer registered with the Engineering Council of South Africa (ECSA), an National Research Foundation (NRF) rated researcher, a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE), a Senior Research Associate in the SARChI Chair in Innovation Studies at the Tshwane University of Science and Technology and Associate Editor of the African Journal of Science, Technology, Innovation and Development (AJSTID). Mammo Muchie founded the African Journal on Science, Technology, Innovation and Development (AJSTID) in 2008 and has served as its Editor-in-Chief, ever since. He has been given the Best Institutional Senior Researcher of the Year Merit and the Academic Excellence Award. Professor Muchie’s scholarly contribution to the discipline of innovation has been in strengthening and contextualising the theoretical framework of National Innovation Systems as applied to the African context. Without his work, the principles and theory of the National Innovation Systems, as they are practised in the developed and industrial economies, could not be applied directly to the developing or under-developed and largely agrarian economies of the African continent.

"Mathematics is an important part of most branches of engineering. Students who ignore Mathematics at High School level may lose several job opportunities in future, because mathematics is used in every area and has many career options. Strong curriculum that incorporates various applications of mathematics into engineering is lacking in our most African universities. This book has tried to address various gaps and put various strategies that inspires our young generation."Dr Getachew Temesgen; Tshwane University of Technology, South Africa"This book on mathematical modelling and engineering design, which comes out after the knowledge exchange from the third AfricaLics Conference in Oran (Algeria), and other AfricaLics academies, is very inspiring. Having been engaged in the process, I know that the book will be very useful to stimulate quality research – the results of which will continue to address the challenges in the African context and to fill a gap on this very important topic.I strongly recommend that the book is integrated into the curriculum of the African education system. It is a knowledge- and resource-rich book that is timely and essential to promote African knowledge."Professor Abdelkader Djeflat, Professor of Innovation Studies at Lille University, France and Chair, The Maghtech Network (www.maghtech.org)"I highly recommend this book for scholars and researchers involved in Science, Technology, Engineering and Mathematics (STEM) education and research. Mathematical modelling and engineering design together offer a valuable analytical tool to engage STEM-related challenges. The diversity of the contributions shows the richness scholars and researchers will be able to draw on. This is an easy-to-read book, providing multiple perspectives for the reader. In a post-COVID-19 context, a book as this can offer both interdisciplinary and multidisciplinary perspectives to better engage problems. The book will surely enrich a global audience."Dr Emmanuel Ojo; University of the Witwatersrand, Johannesburg, South Africa
