Present time Industry 4.0 is the need of all industries because it connects industries to AI, high productivity, safety, and flexibility, ensures the 100% utilization of resources across diverse manufacturing systems, and could accelerate normal manufacturing systems to advanced manufacturing systems by using robotics, additive manufacturing, and many more. In this book, the collection of selected papers is constituted from the International Conference on Progressive Research in Industrial & Mechanical Engineering (PRIME 2021), which was at the National Institute of Technology (NIT), Patna, India from August 5 to 7, 2021. This conference brings together all academic people, industry experts, and researchers from India as well as abroad for involving thoughts on the needs, challenges, new technology, opportunities threats in the current transformational field of aspire. This book deliberates on several elements and their relevance to hard-core areas of industrial and mechanical engineering including design engineering, production engineering, indus trial engineering, automobile engineering, thermal and fluid engineering, mechatronics control robotics, interdisciplinary, and many new emerging topics that keep potential in several areas of applications. This book focuses on providing versatile knowledge of cut ting-edge practices to all readers, helping to develop a clear vision toward Industry 4.0, robotics automation, and additive manufacturing in this demanding and evolving time. The book will be a treasured reference for students, researchers, and professionals inter ested in mechanical engineering and allied fields.

"Now that economic development is starting to pick up in many countries in Africa, the question arises how such development can be balanced with the need for adequate environmental protection. This crucial issue, inherent in the notion of sustainable development, is addressed in this innovative and path-breaking volume. For the first time, academics from seventeen African countries have joined forces to analyse the way in which economic and environmental interests are balanced in their legal systems. The authors all use a common framework to improve the comparability of the country studies. The different country-related chapters do not only provide insights into the formally applicable legal rules (law in the books), but given that the book brings together academics aware of the practice in Africa, they also describe the way in which environmental policy functions in practice (law in action). Many case studies, with conceptual analyses are provided of pollution incidents and the way in which administrative agencies or courts have on those occasions balanced the interests between the economy, society and the environment. A critical comparative analysis by the editors points at tendencies towards convergence and points of divergence between the African countries. Suggestions for policy reform are also formulated, showing African countries how they can benefit from experiences in the US and Europe. This thought provoking volume is a must for anyone (academic, policymaker or practitioner) interested in sustainable development generally and in Africa in particular."--P. [4] of cover.
