The 55th volume of "International Journal of Engineering Research in Africa" is compiled from the peer-reviewed manuscripts that present the research results in applied and fluid flow mechanics, computational analysis of heat and mass transfer processes, and investigation of the chaotic systems. This volume also considered the conceptual model for mitigating security vulnerabilities in smart grid electric energy distribution systems. The last research results in materials science and materials processing technologies, anti-corrosive coating, biodiesel synthesis, wastewater treatment technologies, and waste recycling are presented.

We present the 56th volume of the "International Journal of Engineering Research in Africa" to our readers. The collection contains the articles reflecting the research results in the fields of structural steel and alloys, development of composites, applied mechanics and mechanical engineering, experimental investigations of cement and concrete properties, assessment of the seismic resistance of structures, reliable preventive maintenance scheduling in power systems, cloud computing technology in Cloud of Things, evaluation of sustainable transportation system. The articles will be helpful for many engineers, academic teachers, and students majoring in the mentioned branches of engineering science.

The 47th volume of "International Journal of Engineering Research in Africa" contains articles describing the research results in the fields of development of new building materials and construction technologies, environmental impacts assessment of modern building technologies and materials, and also the implementation of sustainable technologies in architecture and building industry. The articles will be useful for many engineers as well as for academic teachers and students majoring in architecture and modern construction.

The 64th volume of the journal represents the research results of mechanical properties and delamination mode of a carbon-fibre-reinforced polymer composite, experimental and numerical studies of viscoelastic behaviour of bituminous mixture with a high rate of reclaimed asphalt pavement, optimisation of energy consumption for a synthetic ammonia's production, modelling of heat processes in the systems that use solar energy and energy management in a related microgrid. There are articles devoted to image processing for automatic navigation technology in agricultural machines and the development of a hybrid artificial Intelligence-based system for supporting the eco-industrialisation of complex manufacturing processes. The volume will be helpful to specialists in machinery, construction, thermal engineering, usage of solar energy, renewable energetics and industrial automation.

This journal's issue includes articles that describe the latest research results in alloy metallurgy, building materials and construction technologies including building seismic provision and results of analytical modelling of mechanical properties of shrink-fitted thick-walled cylinders and nose landing gear for Boeing 777. There is also analysed a hybrid system solar chimney-air soil heat exchanger for natural ventilation and modified particle swarm optimisation for maximum power point tracking for solar photovoltaic systems and presented mathematical modelling of agricultural insurance pricing in Morocco. This volume will be helpful to many engineers in machinery, manufacturing, energy industry and construction.

This book comprises select proceedings of the International Conference on Production and Industrial Engineering (CPIE) 2018. The book focuses on the latest developments in the domain of operations management and systems engineering, and presents analytical models, case studies, and simulation approaches relevant to a wide variety of systems engineering problems. Topics such as decision sciences, human factors and ergonomics, transport and supply chain management, manufacturing design, operations research, waste management, modeling and simulation, reliability and maintenance, and sustainability in operations and manufacturing are discussed in this book. The contents of this book will be useful to academics, researchers and practitioners working in the field of systems engineering and operations management.

African nations are seeking ways to build strong institutions that are development-oriented and people-centred. Extant literature has reported the negative consequences of ineffective government communications with the public. In response, this book — the first of a two-volume edited work — focuses on marketing communication themes related to branding, public relations, trade fairs and exhibitions, and public sector communications. Public sector marketing communication plays a crucial role in bridging the gap between society and the government. Building a relationship with the public through appropriate communication tools and platforms is sacrosanct to restoring public sector image and trust. The book supports this effort by sharing conceptual and theoretical research towards the marketisation of Africa’s public sector as it strives to become an effective partner with the public it serves. Together with the second volume, which focuses on traditional and digital perspectives, this collection fills an existing information gap that is evident in Africa’s public sector.
