Additive manufacturing, which was first invented in France and then applied in the United States, is now 33 years old and represents a market of around 5 billion euros per year, with annual growth of between 20 and 30%. Today, additive manufacturing is experiencing a great amount of innovation in its processes, software, engineering and materials used. Its strength as a process has more recently allowed for the exploration of new niches, ranging from applications at nanometer and decameter scales, to others in mechanics and health. As a result, the limitations of the process have also begun to emerge, which include the quality of the tools, their cost of manufacture, the multi-material aspects, functionalities and surface conditions. Volume 2 of this series presents the current techniques, improvements and limits of additive manufacturing, providing an up-to-date review of this process.
With a turnover of some 5-15 billion € / year, the additive manufacturing has industrial niches bearers thanks to processes and materials more and more optimized. While some niches still exist on the application of additive techniques in traditional fields (from jewelery to food for example), several trends emerge, using new concepts: collective production, realization of objects at once (without addition Of material), micro-fluidic, 4D printing exploiting programmable materials and materials, bio-printing, etc. There are both opportunities for new markets, promises not envisaged less than 10 years ago, but difficulties in reaching them.
Any time objects and their (self-)organization are to be put into use, their models and methods of thinking as well as their designing and manufacturing need to be reinvented. 4D printing is a future technology that is capable of bringing 3D objects to life. This ability, which gives objects the power to change shape or properties over time through energy stimulation from active materials and additive manufacturing, makes it possible to envisage technological breakthroughs while challenging the relationship between people and objects. 4D Printing 1 presents the different facets of this technology, providing an objective, critical and even disruptive viewpoint to enable its existence and development, and to stimulate the creative drive that industry, society and humanity need in the perpetual quest for evolution and transformation.
Optimization is central to any problem involving decision-making in engineering. Optimization theory and methods deal with selecting the best option regarding the given objective function or performance index. New algorithmic and theoretical techniques have been developed for this purpose, and have rapidly diffused into other disciplines. As a result, our knowledge of all aspects of the field has grown even more profound. In Optimization for Engineering Problems, eminent researchers in the field present the latest knowledge and techniques on the subject of optimization in engineering. Whereas the majority of work in this area focuses on other applications, this book applies advanced and algorithm-based optimization techniques specifically to problems in engineering.
Inventing isn’t easy! After identifying and presenting the 12 "valleys of death", the real obstacles limiting the transition from an original idea to an innovative one, including the notion of socially responsible research, Knowledge Production Modes between Science and Applications 2 applies the concepts introduced in Volume 1. The book starts off with 3D printing, which has essentially broken through all barriers by offering remarkable advantages over existing mechanical technology. The situation is different for 4D printing and bio-printing. First of all, we need to tackle the complexity inherent in these processes, and move away from disciplinarity to find robust, applicable solutions, despite the obstacles. This is possible in niche areas, but currently, low profitability still limits their general applicability and the willingness of researchers to embrace interdisciplinary convergence....
This book covers various modern theoretical, technical, practical and technological aspects of computerized numerical control and control systems of deterministic and stochastic dynamical processes.
Inventing isn’t easy! In this book, twelve “valleys of death” are identified which, following a linear approach, correspond to the various obstacles that limit the various passages from an original idea to invention, and then to industrial innovation. These various limiting factors have a variety of origins: disciplined scientific training, weak general and scientific culture, New Public Management, hierarchical support, funding, evaluation, proof of concepts, complexity management, and heuristic and interdisciplinary approaches on the one hand, and attractiveness for the new on the other. After an idea is formulated, these contexts bring small elements of science into play, but above all human aspects ranging from motivation and the quality of exchanges to responsibility. In short, it is a possible dynamic way of living together to promote innovations stemming from science. This is not easy, but if the invention is profitable for society, the downstream sector can greatly facilitate the various stages of commercialization.
In February 2020, the Coronavirus pandemic became a worldwide health emergency, and in April of that year, the ITU and the WHO created a joint declaration to show their commitment to using ICTs to overcome the pandemic. Technologies and African Societies in Pandemic Times explores the impact of Covid-19 on African societies in North and West Africa through the lens of technology and social media. The authors of this book highlight how everyday people dealt with the pandemic from its onset, through the process of the development of the vaccine and to its eventual dissemination. This book tells stories of survival, of coping and, eventually, of economically thriving. The authors also describe how, in this extremely challenging moment for humanity, people used music, art and social media to reinvent the community, to share joy and pain and to try to remain connected.
The integration and use of information and communication technologies (ICT) in African countries is increasingly observable in various sectors of activity (banking, education, trade, etc.) despite a digital divide still relevant. ICT has become a major sector of the recent growth of a new informal economy in African cities (Chéneau-Loquay, 2008). This question has been at the heart of various international meetings. An overall positive and even utopian momentum is generally heard about the contribution of digital technologies to the development of African states. The adoption or appropriation of digital technologies by Africans is presented in many speeches by politicians or institutions involved in the field of cooperation and international development as an important issue for the development of this continent. These different considerations give rise to reflections on the following themes. - Social Media and Public Space in Africa - Challenges of the digital economy in Africa - ICT and modernization of higher education in Africa
Connected Innovation and Technology X.0 1 studies the development of industry and logistics through digital technologies, presenting novel approaches to efficiency and innovation. It highlights the core of Industry X.0, showing how the digital transformation of business models, the focus on human-centric experiences and the application of advanced technologies all drive growth across various fields. Emphasizing smart supply chain management, performance optimization and sustainable solutions, the book provides insights into using Industry X.0 technologies to enhance supply chain sustainability, network security, and innovation in the manufacturing, healthcare and energy sectors. By integrating lean methodologies, advanced planning and the latest tech solutions, it serves as an efficient resource, not only for professionals, but also for students who seek to map digital transformation complexities and seize the opportunities given to develop future-oriented business models and achieve operational excellence.
