Today's information technology, along with Artificial Intelligence (AI), is moving towards total communication between all computerized systems. AI is a representation of human intelligence based on the creation and application of algorithms in specific computer environments. Its aim is to enable computers to act like human beings. For it to work, this type of technology requires computer systems, data with management systems and advanced algorithms, used by AI. In mechanical engineering, AI can offer many possibilities: in mechanical construction, predictive maintenance, plant monitoring, robotics, additive manufacturing, materials, vibration control and agro composites, among many others. This book is dedicated to Artificial Intelligence uncertainties in mechanical problems. Each chapter clearly sets out used and developed illustrative examples. Aimed at students, Uncertainty and Artificial Intelligence is also a valuable resource for practicing engineers and research lecturers.
At the end of the Second World War, a new technological trend was born: integrated electronics. This trend relied on the enormous rise of integrable electronic devices. Analog Devices and Circuits is composed of two volumes: the first deals with analog components, and the second with associated analog circuits. The goal here is not to create an overly comprehensive analysis, but rather to break it down into smaller sections, thus highlighting the complexity and breadth of the field. This first volume, after a brief history, describes the two main devices, namely bipolar transistors and MOS, with particular importance given to the modeling aspect. In doing so, we deal with new devices dedicated to radio frequency, which touches on nanoelectronics. We will also address some of the notions related to quantum mechanics. Finally, Monte Carlo methods, by essence statistics, will be introduced, which have become more and more important since the middle of the twentieth century. The second volume deals with the circuits that "use" the analog components that were introduced in Volume 1. Here, a particular emphasis is placed on the main circuit: the operational amplifier.
For two centuries, the school system has been a central point around which other players have gravitated: local authorities, voluntary organizations and the world of work. Over the course of the 20th century, this school centric configuration underwent a transformation, with local authorities tending to become integrated into the vertical culture of the school system. This was only the beginning of a process that brought schools and socio cultural players into constant contact. Cultural, Training and Educational Spaces first examines the relationships with knowledge generated by the links between the school system and other cultural, training and educational spaces, taking a historical, pedagogical and philosophical perspective. Easy access to learning materials creates different relationships with knowledge than those observed in schools. The book then looks at the pedagogical practices in these different cultural educational spaces, such as libraries and media libraries, museums and historical sites, places of heritage, history and entertainment, social networks and other multimedia formats.
Complexity is not a new issue. In fact, in their day, William of Ockham and René Descartes proposed what can best be described as reductionist methods for dealing with it. Over the course of the twentieth century, a science of complexity has emerged in an ever-increasing number of fields (computer science, artificial intelligence, engineering, among others), and has now become an integral part of everyday life. As a result, everyone is confronted with increasingly complex situations that need to be understood and analyzed from a global perspective, to ensure the sustainability of our common future. Complexities 1 analyzes how complexity is understood and dealt with in the fields of cybersecurity, medicine, mathematics and information. This broad spectrum of disciplines shows that all fields of knowledge are challenged by complexity. The following volume, Complexities 2, examines the social sciences and humanities in relation to complexity.
Innovation is an essential growth lever for organizations. Like any strategic element, it must be managed to ensure the right decision is made at the right time. When we talk about management, we naturally also consider management control. However, using management tools can be a danger to developing creativity - an essential element of innovation. This book examines the interdependencies between management control and creativity. By comparing two organizational contexts, we highlight the vital role of organizations as generators of creativity. We also underline the acceptance of an imbalance between the elements in tension, which can lead to the questioning and fostering of innovation; and the role of senior management as mediators between organizations and local actors.
Inequalities and other "social fractures" mark our contemporary economies and societies. While global approaches may have long been sufficient in the past, the focus today is on how local dynamics can make inclusion possible. This two-volume collective work reports on these local dynamics, shedding light on how the creation of inclusive territories can be envisaged and developed. To this end, the involvement of public, private and associative organizations has been identified as one of the conditions for success. In fact, they act both as partners in a territory and as inclusive spaces. Inclusive Territories 1 examines the approaches implemented by several organizations that have made inclusion their wider objective.
For a long time, favelas were a source of fear for tourists visiting Rio de Janeiro. Now that they are more appealing, some have become popular tourist destinations even though they are still regarded as an "off the beaten track" activity. Favela Tours analyzes the factors behind the emergence of tourism in the favelas, places of otherness and authenticity for visitors who come mainly from Western Europe and North America. Based on ethnography of those involved in these practices (guides, residents and tourists), this book describes how the local and global forces are converging to make favelas part of the western tourism system: a mechanism for fabricating and assimilating otherness.
This book studies the flow of materials and the influence of strain rates on the relationship between imposed stresses and the dynamic deformations obtained. It provides applications for shaping, molecular molding, shrink-fit assembly and welding, including details of the various specific processes for implementation at high strain rates, illustrated by numerous industrial examples. Rheology, Physical and Mechanical Behavior of Materials 1 presents analyses of plasticity mechanisms at microscopic and macroscopic scales, and of the various forms of stressstrain behavior laws according to working speeds, mechanisms, athermics, viscoplasticity and formability limits at types and speeds of change. It is aimed at researchers involved in the mechanics of deformable media, as well as industrial design and manufacturing departments
Our current situation, marked simultaneously by the Anthropocene, global warming, digitization and exponential artificial intelligence, leads us to sudden and total change in global civilization and, de facto, to rebuilding the foundations of the international economy. Innovation Ecosystems explores the risks and opportunities facing the contemporary world by analyzing, comparing and categorizing the world's most dynamic innovation ecosystems by region and city. This includes the identification of key characteristics - common or original - and learning from them in terms of culture, management, system and structure, in order to meet current challenges and think about civilizations of the future.
Interfaces are present in most fluid mechanics problems. They not only denote phase separations and boundary conditions, but also thin flames and discontinuity waves. Fluid Mechanics at Interfaces 2 examines cases that involve one-dimensional or bi-dimensional manifolds, not only in gaseous and liquid physical states but also in subcritical fluids and in single- and multi-phase systems that may be pure or mixed.Chapter 1 addresses certain aspects of turbulence in discrete mechanics, briefly describing the physical model associated with discrete primal and dual geometric topologies before focusing on channel flow simulations at turbulence-inducing Reynolds numbers. Chapter 2 centers on atomization in an accelerating domain. In one case, an initial Kelvin-Helmholtz instability generates an acceleration field, in turn creating a Rayleigh-Taylor instability which ultimately determines the size of the droplets formed. Chapter 3 explores numerical studies of pipes with sudden contraction using OpenFOAM, and focuses on modeling that will be useful for engines and automobiles.Chapters 4 and 5 study the evaporation of droplets that are subject to high-frequency perturbations, a possible cause of instabilities in injection engines. The Heidmann model, which replaces the droplets in motion in a combustion chamber with a single continuously-fed droplet, is made more complex by considering the finite conduction heat transfer phenomenon. Finally, Chapter 6 is devoted to a study of the rotor blade surface of a Savonius wind turbine, considering both a non-stationary and a three-dimensional flow.
Interfaces are present in most fluid mechanics problems. They not only denote phase separations and boundary conditions, but also thin flames and discontinuity waves. Fluid Mechanics at Interfaces 1 focuses on the science of interfaces, in particular, using various scientific methods of analysis relating to space, speed and time. Our investigation takes us from the microscopic or small scale (starting with molecular and nanoscopic scales) to the macroscopic (including meso and interstellar scales), and also explores the laws of interfaces (classical mechanics, quantum mechanics and relativistic mechanics).Chapter 1 examines the questions raised by modeling interfaces in the presence of one or more fluid phases. Chapter 2 discusses the action of turbulence in liquid-vapor flows that contain both small, dispersed bubbles as well as large bubbles, with heat exchanges at the interfaces. In addition, a new model is presented, using large eddy simulation (LES). Chapter 3 studies an original method for calculating the drag force and thermal transfers in flows around networks of spherical particles, while Chapter 4 focuses on the relationships between interfaces and critical fluids.Chapter 5 examines shearing, which causes anomalies in the Brownian motion of particles in strongly fluctuating near-critical mixtures, and Chapter 6 introduces basic concepts related to combustion interfaces, raising the question of the combustion of solids, before ending with a brief presentation of the Rankine-Hugoniot theory and a historical overview of the research carried out in the field of combustion.
This book presents the applications of non-volatile CBRAM/MIM switching technology for electronically reconfigurable passive RF and microwave devices, together with theory and methods for application in rewritable chipless RFID tags. Conductive Bridging Random Access Memory (CBRAM) is a renowned and commercially used non-volatile memory concept. Having evolved over the past few decades, it is currently identified as an efficient non-volatile RF switching technology.This book presents recent research on this topic, focusing on the development of a new generation of low-cost non-volatile RF switches and their applications, demonstrating both high performance and flexibility of implementation. It includes the experimental realization of various prototypes of RF and microwave devices utilizing this technology, along with relevant analysis of mathematical and electrical models, and detailed discussions of future aspects. All devices presented are compatible with mass industrial production at an economically efficient budget through optimized fabrication steps, without the requirement of sophisticated "clean room" processes among them.
Elastic waves are used in fields as diverse as the non-destructive evaluation of materials, medicine, seismology and telecommunications. Elastic Waves in Solids 1 presents the different modes of propagation of elastic waves in increasingly complex media and structures. It first studies the propagation in an unlimited solid where only the material properties are taken into account. It then analyzes reflection and transmission phenomena at an interface with a fluid or a second solid.It explains the search for propagation modes on a free surface or at the interface between two media. Finally, it proposes a study of the dispersive propagation of elastic waves guided by a plate or a cylinder. This book is intended for students completing a master's degree in acoustics, mechanics, geophysics or engineering, as well as teachers and researchers in these disciplines.

The aim is to take advantage of artificial intelligence, optimization and simulation methods to provide solutions to prevent, anticipate, monitor and follow public health developments in order to intervene at the right time, using tools and resources that are both appropriate and effective.The focus is on the people involved - the patients, as well as medical, technical and administrative staff - in an effort to provide an efficient healthcare and working environment that meets safety, quality and productivity requirements.Heathcare Systems has been written by healthcare professionals, researchers in science and technology as well as in the social sciences and humanities from various French-speaking countries. It explores the challenges and opportunities presented by digital technology in our practices, organizations and management techniques.
Resulting from a conference that took place in Amiens, France, in June 2019, this book examines the place and role of objects centered in teaching practices from kindergarten to university, both in the context of France and elsewhere. These "objects for learning" are considered in their physicality as productions, work or signs that are used for learning. They become "objects to learn about" when the object itself is the learning objective.This book offers a cross-disciplinary perspective, linking the different disciplinary fields studied and the many reference sources used by the authors. This two-volume work offers an overview of current research on the subject, with this second volume focusing on objects in representations of space and time, then on learners' activities in the making or use of objects, before concluding with different cultural and philosophical perspectives on objects
This book covers three principal subject areas: smart cities, general contractors and business models. The smart city concept is currently on the rise and cities around the world appear to be in a race to become smart, fast. Converting big cities into smart cities is a move that almost all cities around the globe have made, or will undoubtedly make in the near future, to be able to cope with the various repercussions of urbanization. Smartness is a vague term that could relate to anything and everything, such as infrastructure, people or governance.In this book, we focus our attention on smart buildings - large ones, in particular - and attempt to identify the key problems that France-based construction companies face today, in order to suggest plausible solutions. Our research findings show that no single business model can fit all smart cities worldwide. Using the general contractor business model for smart cities, this book proposes an original solution to managing smart city projects, bringing together architecture, construction and strategy.
The notion of customer orientation is becoming a necessity rather than a choice for many companies. It is a lasting response to competitive pressure and supports the company in a renewed definition of its mission, beyond direct economic gain. Within B2B services, the manager, through proximity to their team, their market and their client, is the essential actor in the deployment of this orientation.A Customer-oriented Manager for B2B Services provides managers with the knowledge and tools necessary to implement customer orientation themselves, with the involvement of their extended team. To this end, this book presents a four-step approach: understand the fundamentals of customer orientation in B2B services, know the customer, make the most of the offer and deliver the service.
Every parent is concerned when a child is slow to become a mature adult. This is also true for any product designer, regardless of their industry sector. For a product to be mature, it must have an expected level of reliability from the moment it is put into service, and must maintain this level throughout its industrial use.While there have been theoretical and practical advances in reliability from the 1960s to the end of the 1990s, to take into account the effect of maintenance, the maturity of a product is often only partially addressed.Product Maturity 1 fills this gap as much as possible; a difficult exercise given that maturity is a transverse activity in the engineering sciences; it must be present throughout the lifecycle of a product.
Industrial, economic and organizational mutations are creating a transformation in employment, skills and work. Developing the employability of the workforce is one response to these challenges. However, the link between mutations and employability is not obvious: it must be constructed and implemented in order to ensure that employees are able to reach satisfying professional situations.Employability and Industrial Mutations presents a definition of employability and the associated challenges for public authorities, organizations and employees: managing unemployment, successful change and employee empowerment. It then examines several worker profiles to better understand what "being employable" means. It goes on to analyze several examples of management systems for employability at different stages of an individual's career, and finally explores the issue of developing or maintaining employability in real-life situations and contexts.This book brings together researchers and practitioners from a range of different fields in order to shed light on the complex relationship between mutations and employability.
Smart zero-energy buildings and communities have a major role to play in the evolution of the electric grid towards alignment with carbon neutrality policies. The goal to reduce greenhouse gas emissions in the built environment can be pursued through a holistic approach, including the drastic reduction of buildings' energy consumption.The state-of-the-art in this field relates, on the one hand, to design methodologies and innovative technologies which aim to minimize the energy demand at the building level. On the other hand, the development of information and communication technologies, along with the integration of renewable energy and storage, provide the basis for zero and positive energy buildings and communities that can produce, store, manage and exchange energy at a local level.This book provides a structured and detailed insight of the state-of-the-art in this context based on the analysis of real case studies and applications.
This book reviews the current state of knowledge in the field of child and adolescent psychology. It distinguishes between what is new in child psychology, given that certain phenomena did not previously exist in a significant way in the lives of young people (such as homoparentality, attacks, cyber-bullying or Covid-19). It also examines new studies of subjects that already exist and have done so for a long time (intelligence, the mother-child relationship, etc.), but where significant theoretical developments have taken place in the contemporary period.Child Psychology explores the influences of culture and parenthood, parent-child attachment, cognitive development, the differences between boys and girls, gender and its stereotypes, health, illness and mortality, antisociality, activities and leisure
In the field of health, information practices and the organization of knowledge constitute a major challenge today. The practices of the medical profession, or of patients, are evolving under the influence of digital technology. At the same time, the way in which medical knowledge is organized, represented and mediated is also evolving.Information Practices and Knowledge in Health addresses the different aspects of the field of specialized medical and health information; it focuses on the informational practices of professionals in the sector, of patients and, more broadly, of citizens with regards to their health. This book also considers the systems that are used for organizing knowledge in this field.

The universe is considered an expansive informational field subjected to a general organizational law. The organization of the deployment results in the emergence of an autonomous organization of spatial and material elements endowed with permanence, which are generated on an informational substratum where an organizational law is exercised at all scales. The initial action of a generating informational element produces a quantity of basic informational elements that multiply to form other informational elements that will either be neutral, constituting the basic spatial elements, or active, forming quantum elements.The neutral basic elements will form the space by a continuous aggregation and will represent the substrate of the informational links, allowing the active informational elements to communicate, in order to aggregate and organize themselves.Every active element is immersed in an informational envelope, allowing it to continue its organization through constructive communications. The organizational law engages the active quantum elements to aggregate and produce new and more complex quantum elements, then molecular elements, massive elements, suns and planets. Gravity will then be the force of attraction exerted by the informational envelopes of the aggregates depending on their mass, to develop them by acquisition of new aggregates.The organizational communication of the informational envelopes of all of the physical material elements on Earth will enable the organization of living things, with reproduction managed by communications between the informational envelopes of the elements, realizing a continuous and powerful evolution.
This book centers on climate change, a pressing issue in the ecological transition, particularly for landscape and architecture schools.The scientific realities and consequences of this phenomenon are becoming increasingly well-known and it is now evident that architecture, urban planning and landscaping all have the potential to mitigate these consequences.Ecological Transition in Education and Research is a multidisciplinary collective work, intended to raise awareness of adaptation and mitigation strategies such as action-research, educational innovations and concrete transition practices that embrace different schools of thought. The overall goal is to promote educational practices and research on climate change.
The digital transformation of companies is both a competitive challenge and a complex step for large groups and industries, and at the same time a tremendous opportunity. This transformation is entering a new dimension with the development of immersive technologies such as virtual reality, mixed reality and augmented reality, which are revolutionizing the way we generate content as well as visualize and interact with models and data.The challenges of innovation and digital transformation within companies are now converging. Research shows the potential that immersive technologies have to accelerate the first steps of the innovation process.The objective of this book is to provide a clear vision of the state of research on immersive technologies for design and to deliver practical recommendations for companies wishing to improve their innovation process.
In the automotive and aerospace industries, the need for strong yet light materials has given rise to extensive research into aluminum and magnesium alloys and formable titanium alloys. All of these are categorized as light weight materials. The distinguishing feature of light weight materials is that they are low density, but they have a wide range of properties and, as a result, a wide range of applications. This book provides researchers and students with an overview of the recent advancements in light weight material processing, manufacturing and characterization. It contains chapters by eminent researchers on topics associated with light weight materials, including on the current buzzword "composite materials". First, this book describes the current status of light weight materials. Then, it studies applications of these materials, given that, as the densities vary, so do the applications, ranging from automobiles and aviation to bio-mechatronics. This book will therefore serve as an excellent guide to this field.
In order to describe soil-structure interaction in various situations (nonlinear, static, dynamic, hydro-mechanical couplings), this book gives an overview of the main modeling methods developed in geotechnical engineering. The chapters are centered around: the finite element method (FEM), the finite difference method (FDM), and the discrete element method (DEM). Deterministic Numerical Modeling of Soil-Structure Interaction allows the reader to explore the classical and well-known FEM and FDM, using interface and contact elements available for coupled hydro-mechanical problems.Furthermore, this book provides insight on the DEM, adapted for interaction laws at the grain level. Within a classical finite element framework, the concept of macro-element is introduced, which generalizes constitutive laws of SSI and is particularly straightforward in dynamic situations. Finally, this book presents the SSI, in the case of a group of structures, such as buildings in a town, using the notion of metamaterials and a geophysics approach.
Capturing, recording and broadcasting the voice is often difficult. Many factors must be taken into account and achieving a true representation is much more complex than one might think.The capture devices such as the position of the singer(s) or narrator(s), the acoustics, atmosphere and equipment are just some of the physical aspects that need to be mastered. Then there is the passage through the analog or digital channel, which disrupts the audio signal, as well as the processes that are often required to enrich, improve or even transform the vocal timbre and tessitura. While in the past these processes were purely material, today digital technologies and software produce surprising results that every professional in recording and broadcasting should know how to master.Recording and Voice Processing 2 focuses on live and studio voice recordings. It presents the various pieces of hardware and software necessary for voice recording, and details possible sound channel configurations based on recording location. An actual recording, and its various constraints, is then considered, addressing the pitfalls to avoid and the strategies to use in order to achieve a satisfactory result. Different special effects (vocoder, auto-tune, Melodyne, etc.) that can be used on the voice, whether spoken or sung, are also presented.
The concept of digital risk, which has become ubiquitous in the media, sustains a number of myths and beliefs about the digital world. This book explores the opposite view of these ideologies by focusing on digital risks as perceived by actors in their respective contexts.Perceptions and Analysis of Digital Risks identifies the different types of risks that concern actors and actually impact their daily lives, within education or various socio-professional environments. It provides an analysis of the strategies used by the latter to deal with these risks as they conduct their activities; thus making it possible to characterize the digital cultures and, more broadly, the informational cultures at work.This book offers many avenues for action in terms of educating the younger generations, training teachers and leaders, and mediating risks.
