These proceedings represent the work of contributors to the 24th European Conference on Knowledge Management (ECKM 2023), hosted by Iscte – Instituto Universitário de Lisboa, Portugal on 7-8 September 2023. The Conference Chair is Prof Florinda Matos, and the Programme Chair is Prof Álvaro Rosa, both from Iscte Business School, Iscte – Instituto Universitário de Lisboa, Portugal. ECKM is now a well-established event on the academic research calendar and now in its 24th year the key aim remains the opportunity for participants to share ideas and meet the people who hold them. The scope of papers will ensure an interesting two days. The subjects covered illustrate the wide range of topics that fall into this important and ever-growing area of research. The opening keynote presentation is given by Professor Leif Edvinsson, on the topic of Intellectual Capital as a Missed Value. The second day of the conference will open with an address by Professor Noboru Konno from Tama Graduate School and Keio University, Japan who will talk about Society 5.0, Knowledge and Conceptual Capability, and Professor Jay Liebowitz, who will talk about Digital Transformation for the University of the Future. With an initial submission of 350 abstracts, after the double blind, peer review process there are 184 Academic research papers, 11 PhD research papers, 1 Masters Research paper, 4 Non-Academic papers and 11 work-in-progress papers published in these Conference Proceedings.

This book covers the areas of fundamentals in energy conservation and its applications in selected industries. There are nine chapters in this book which have been written by leading experts in energy from all over the world. The topics range from energy fundamentals from cosmic radiation, tidal waves and dams. The chapters examine the potential of utilizing energy from sustainable resources and how energy consumption may be conserved from various new technologies. The contents of this book include space energy, barotropic and baroclinic tidal energy, understanding energy conservation in biological context, Earth shelters, hydro power, biofuel from groundnut oil and low energy consumption in industrial production. This book is suitable as a reference for students, educators, researchers, scientists, engineers and energy practitioners. It will also be a useful for the understanding of energy fundamentals, design and applications.

This book presents a novel framework design for the next generation Marine Wireless Communication Networks (MWCNs). The authors first provide an overview of MWCNs, followed by a discussion of challenges in the design and development of MWCNs in support of a diversity of marine services such as real-time marine monitoring, offshore oil exploration, drilling, marine tourism and fishing. The authors then propose cross layer networking solutions to achieve a high performance modern MWCN that enables efficient and reliable data transmissions under hostile marine environment, which include the network deployment, the physical layer channel coding, intelligent network access and resource management, and learning-based opportunistic routing. Finally, the authors summarize the book and present some open issues that will lead to new research directions in the next generation MWCNs.

Plastic pollution is a complex environmental problem. The use of recycled plastics in the modification of concrete materials has a dominant role to play in the move towards sustainable construction. Reuse of Plastic Waste in Eco-efficient Concrete presents the latest research findings on the application and use of recycled plastic waste in sustainable construction. Divided over four parts, the chapters cover various techniques for processing and separation of plastic wastes; use of recycled plastics as aggregates in modified concrete; as well as lightweight reinforced concrete applications too. There is also an entire section dedicated to asphalt mixtures. The book provides technological solutions on how recycled plastic wastes can be applied in concrete manufacturing. It will be a valuable reference source for academic and industrial researchers who are working with waste materials and the use of recycled plastics in concrete, as well as for civil and structural engineers, polymer production technologists, and concrete manufacturers. - Describes the main types of recycled plastics that can be applied in concrete manufacturing - Presents, state-of-the art knowledge on the properties of conventional concrete with recycled plastics - Discusses the technological challenges for concrete manufacturers for mass production of recycled concrete from plastic waste - Covers lifecycle cost analysis, production challenges, and long-term performance analysis
