Fatigue damage in a system with one degree of freedom is one of the two criteria applied when comparing the severity of vibratory environments. The same criterion is also used for a specification representing the effects produced by the set of vibrations imposed in a real environment. In this volume, which is devoted to the calculation of fatigue damage, Christian Lalanne explores the hypotheses adopted to describe the behavior of material affected by fatigue and the laws of fatigue accumulation. The author also considers the methods for counting response peaks, which are used to establish the histogram when it is not possible to use the probability density of the peaks obtained with a Gaussian signal. The expressions for mean damage and its standard deviation are established and other hypotheses are tested.
During the first decade of this new millennium, it is estimated that more than EUR100 billion will be invested in the third generation (3G) Universal Mobile Telecommunications System (UMTS) in Europe. This fact represents an amazing challenge from both a technical and commercial perspective. Written by experts in the field, this book gives a detailed description of the elements in the UMTS network architecture: the User Equipment (UE), the UMTS Radio Access Network (UTRAN) and the core network. The completely new protocols based on the needs of the new Wideband Code Division Multiple Access (WCDMA) air interface are highlighted by considering both Frequency- and Time-Division Duplex modes. The book further introduces the key features of existing topics in Releases 5, 6 and 7.
Providing healthcare professionals with cognitive aids, whether a simple checklist or an information system, improves patient care and reduces information-processing constraints for caregivers. However, to achieve these objectives, these aids must be adaptable and ergonomic.
Cognitive Aids to Support Healthcare Professionals offers an unprecedented presentation of the different forms of cognitive aids, as well as an analysis of these aids as gateways for channelling resources to support mental activity and a general framework to simply model cognitive aids as Turing machines.
Throughout this book, healthcare professionals, executives, hospital managers, healthcare engineers, ergonomists and trainers will find ergonomic advice on the choice or design of cognitive aids, and also, more generally, on the roles that cognitive aids play in activities.
Monitoring the human body is a key element of digital health science. Low-cost sensors derived from smartphones or smartwatches may give the impression that sensors are readily available; however, to date, very few of them are actually medical devices.
Designing medical devices requires us to undertake a specific approach demanding special skills, as it concerns the integrity of the human body. The process is tightly framed by state regulations in order to ensure compliance with quality assessment, risk management and medical ethics requirements.
This book aims to give biomedical students an overview on medical devices design. It firstly gives a historical and economical approach, then develops key elements in medical device design with reference to EU and US regulations, and finally describes sensors for the human body. The clinical approach is presented as the central element in medical device qualification and this offers a perspective on the use of numerical simulation, particularly since its continued growth in the USA; despite the fact that the approach is strictly limited by regulations.
Traditionally, health experts are called upon mainly by public authorities and academic circles. In recent years, however, thanks to the proliferation of media, 24-hour news channels and digital offerings, there is a growing demand for expert opinions on various health issues. Expert knowledge can, of course, come from doctors and scientists, however it is not limited to them. Patient associations, caregiver circles, patient influencers, YouTubers and specialist journalists are speaking out, which raises questions concerning the place of the "expert" and the nature of their expertise. Health Experts in the Media examines health experts' place in the media in order to define the complexity of their role, question their legitimacy and better understand the controversies they generate. This book analyzes how expert discourse in the media can raise major scientific, democratic and political issues.

The energy sector is undergoing unprecedented change. Twenty years ago, the main concern was having enough oil and gas, whereas today, political leaders are faced with the need to reduce the CO2 emissions produced by still-dominant fossil fuels, without being able to totally rely on renewable energies, which are intermittent and whose share in energy production remains low.
Geopolitics and Energy Transition 1 presents the technical aspects of energy and its main characteristics, and outlines the challenges of the energy transition, the conditions for the development of renewable energies and the geopolitical stakes of this transition. It also describes the various energy markets and the consequences of liberalization policies, not forgetting to analyze the structures of the different sectors, while pointing out the fundamental problems of supply security and ways of strengthening it.
Our knowledge of living organisms is still very limited, with less than 20% of the world's species known to date. It is therefore essential to increase our efforts to inventory biodiversity. This is the goal of scientific research, but it is also a vital responsibility in the face of the sixth extinction. With so many species set to disappear before they can be analyzed, the compilation of this inventory now represents a major challenge.
Thanks to the collaborative work of numerous researchers from the Institut de systématique, évolution, biodiversité (ISYEB) and other institutions, Inventory of Biodiversity Today presents the latest methods of field data collection and analysis. Strategies have diversified and are providing new and ever-more-precise data on a growing number of specimens. All of these data are integrated to delimit and describe living species, and are accessible to as many people as possible, so we can all take action on a daily basis to better understand and preserve our planet.
Geotechnical engineering is now a fundamental component of construction projects. The second volume of this book addresses the fundamental principles of soil mechanics and the role of water in geotechnical projects and assessments. Applied Geotechnics for Construction Projects 2 outlines the hydraulic properties of soils and the basic concepts of water in soil, detailing the principles of permeability measurement tests and giving concrete test cases, and then goes on to outline the basic notions of soil mechanics as applied in geotechnics: from consolidation to short- and long-term notions via the swelling phenomena of clayey soils, soil shear strength and slope stability. The third chapter presents a comprehensive overview of geotechnical expertise using examples of concrete projects either with or without damage in the context of geotechnical construction works. Each chapter of this second volume provides concrete examples of applications to real projects and the rules and lessons we must remember. The result is a combination of geotechnical expertise and lessons learned from experience, both of which are highly valuable in the field of applied geotechnics for construction projects.
From queues to telecoms. Queues are, of course, omnipresent in our world, at the bank, the supermarket, the shops, on the road... and yes, they also exist in the domain of telecoms. Queues Applied to Telecoms studies the theoretical aspect of these queues, from Poisson processes, Markov chains and queueing systems to queueing networks. The study of the use of their resources is addressed by the theory of teletraffic. This book also outlines the basic ideas in the theory of teletraffic, presenting the teletraffic of loss systems and waiting systems. However, some applications and explanations are more oriented towards the field of telecommunications, and this book contains lectures and more than sixty corrected exercises to cover these topics. On your marks....
This book studies formal semantics in modern type theories (MTTsemantics). Compared with simple type theory, MTTs have much richer type structures and provide powerful means for adequate semantic constructions. This offers a serious alternative to the traditional settheoretical foundation for linguistic semantics and opens up a new avenue for developing formal semantics that is both model-theoretic and proof-theoretic, which was not available before the development of MTTsemantics. This book provides a reader-friendly and precise description of MTTs and offers a comprehensive introduction to MTT-semantics. It develops several case studies, such as adjectival modification and copredication, to exemplify the attractiveness of using MTTs for the study of linguistic meaning. It also examines existing proof assistant technology based on MTT-semantics for the verification of semantic constructions and reasoning in natural language. Several advanced topics are also briefly studied, including dependent event types, an application of dependent typing to event semantics.
Over the past decades, the use of quantitative methods has become almost generalized in all domains of linguistics. However, using these methods requires a thorough understanding of the principles underlying them. Introduction to quantitative methods in linguistics aims at providing students with an up-to-date and accessible guide to both corpus linguistics and experimental linguistics. The objectives are to help students developing critical thinking about the way these methods are used in the literature and helping them to devise their own research projects using quantitative data analysis.
The book has a dual purpose. The first is to expose a general methodology to solve problems of electromagnetism in geometries constituted of angular regions. The second is to bring the solutions of some canonical problems of fundamental importance in modern electromagnetic engineering with the use of the Wiener-Hopf technique.
In particular, the general mathematical methodology is very ingenious and original. It is based on sophisticated and attractive procedures exploiting simple and advanced properties of analytical functions. Once the reader has acquired the methodology, they can easily obtain the solution of the canonical problems reported in the book. The book can be appealing also to readers who are not directly interested in the detailed mathematical methodology and/ or in electromagnetics. In fact the same methodology can be extended to acoustics and elasticity problems. Moreover, the proposed practical problems with their solutions constitute a list of reference solutions and can be of interest in engineering production in the field of radio propagations, electromagnetic compatibility and radar technologies.
To develop innovations in quantum engineering and nanosystems, designers need to adopt the expertise that has been developed in research laboratories. This requires a thorough understanding of the experimental measurement techniques and theoretical models, based on the principles of quantum mechanics. This book presents experimental methods enabling the development and characterization of materials at the nanometer scale, based on practical engineering cases, such as 5G and the interference of polarized light when applied for electromagnetic waves. Using the example of electromechanical, multi-physical coupling in piezoelectric systems, smart materials technology is discussed, with an emphasis on scale reduction and mechanical engineering applications. Statistical analysis methods are presented in terms of their usefulness in systems engineering for experimentation, characterization or design, since safety factors and the most advanced reliability calculation techniques are included from the outset. This book provides valuable support for teachers and researchers but is also intended for engineering students, working engineers and Master?s students.
TECHNOLOGICAL CHANGES AND HUMAN RESOURCES SET Coordinated by Patrick Gilbert The accelerating pace of technological change (AI, cobots, immersive reality, connected objects, etc.) calls for a profound reexamination of how we conduct business. This requires new ways of thinking, acting, organizing and collaborating in our work. Faced with these challenges, the Human and Social Sciences have a leading role to play, alongside others, in designing, supporting and implementing these digital transformation projects. Their ambition is to participate in the development of innovative and empowering devices, that is to say, systems that are truly at the service of human beings and their activity, that empower these professionals to take action and that also provide occupational health services. This book takes a multidisciplinary look at the challenges of these digital transformations, making use of occupational psychology, ergonomics, sociology of uses, and management sciences. This viewpoint also helps provide epistemological, methodological and empirical insights to better understand and support the changes at work.
The emergence of a true systemic science - the systemic one - capable of rigorously addressing the many problems posed by the design and management of the evolution of modern complex systems is therefore urgently needed if wants to be able to provide satisfactory answers to the many profoundly systemic challenges that humanity will have to face at the dawn of the third millennium. This emergence is of course not easy because one can easily understand that the development of the systemic is mechanically confronted with all the classical disciplines which can all pretend to bring part of the explanations necessary to the understanding of a system and which do not naturally see a good eye a new discipline claim to encompass them in a holistic approach ... The book of Jacques Printz is therefore an extremely important contribution to this new emerging scientific and technical discipline: it is indeed first of all one of the very few "serious" works published in French and offering a good introduction to the systemic. It gives an extremely broad vision of this field, taking a thread given by the architecture of systems, in other words by the part of the systemic that is interested in the structure of systems and their design processes, which allows everyone to fully understand the issues and issues of the systemic. We can only encourage the reader to draw all the quintessence of the masterful work of Jacques Printz which mixes historical reminders explaining how the systemic emerged, introduction to key concepts of the systemic and practical examples to understand the nature and the scope of the ideas introduced.
The book explores, discusses, and considers new and innovative perspectives on the crossings, interactions, and transformations of non-formal, informal learning, and formal learning within or prior to FADS and Internship. The contributions provide a wider perspective on the alternating Final Architectural Design Studios and Internship programs as interfaces and interaction zones among different learning experiences that lead to professional and intellectual qualification.
This comprehensive scientific work embraces, within the generic theme of "educations, territorialities and territories", the vast majority of different facets of the complex relationships between educations and territories that have developed over time. It sheds an original light on the many - and, for some, new - interactions between territories-territories, on the one hand, and educations, on the other hand, which have recently been identified and analyzed. Beyond this main objective, it contributes to improving the fine and differentiated understanding of the concept of territory in the sciences of education and training and, more importantly, it brings innovative developments to the still embryonic theorization of the complex relations between educations. and territories-territorialities. This book shows, in particular, through its surveys, its analyzes and its results, that within all the multiple influences attributed to the different dimensions of the territories, the very discrete territoriality - falling within the symbolic territory - is perhaps finally the the most important territorial vector in terms of education in certain areas (rural Montagnards, for example), particularly as regards educational and vocational guidance, but not only. Lastly, it is not uninteresting to note that the theme it bears is spreading more and more today beyond scientific circles: the problem of inequalities in education and orientation of territorial origin is fueling - recently - the controversies and the reflections of the French educational policy which is thus sometimes echoed - in declarative terms essentially for the moment! - scientific advances in this area
The risk of explosion is inseparable from industrial activity, as we are often reminded by the news. In order to avoid an explosion, it is necessary to understand the phenomena surrounding it, and take the necessary preventive measures to protect society if it comes to the worst-case scenario. This book will detail these phenomena. The Mechanisms of Explosions presents theoretical aspects from a physicochemical point of view and proposes various methods adapted to each type of explosion, including ATEX explosions. The author shares his knowledge of the mechanisms of explosions, acquired during numerous investigations. These 27 case studies - detailing circumstances, mechanisms and the nature and intensity of explosive effects - were selected to cover all of the possible physical or chemical phenomena, substances and mechanisms, without limiting themselves to the most common situations. This book, packed full of information, is designed to benefit those who analyze and investigate explosions, particularly insurance and judicial experts, prevention engineers, security managers and trainers.
Organizations, both private and public, are now evolving in a globalized "information society" that has been accelerated by digitization. They find themselves drawn into a spiral of transformations fueled by the incessant reinvention of information and communication technologies (ICT) that are changing digital uses and practices. They transform through the mediating action of ICTs, work activities and associated action situations. Platform and Collective Intelligence analyzes a specific declination of an organization that has become irreversibly reticular: the "platform organization". The network, at the heart of this new conception, proposes a model combining cybernetics and computing. The organization can thus be seen as an interface for contact, via its information systems, for employees or citizens, whatever their geographical location. With a view going beyond technocentrism and technological determinism, this book combines collective intelligence and sociotechnics with the platform to arrive at the notion of "organizational experience".
The text sets out in simple and accessible terms the various methods of acoustic analysis of speech, placing them in their historical context, allowing a better understanding of the mathematical and technical solutions adopted today in phonetics and experimental phonology. Without mathematical complications, the operating bases of the many speech analysis software currently available are exposed so that everyone can understand the limits and avoid errors and misinterpretations in their implementation.
This book is the first of two volumes on random motions in Markov and semi-Markov random environments. This first volume focuses on homogenous random motions. This volume consists of two parts, the first describing the basic concepts and methods that have been developed for random evolutions. These methods are the foundational tools used in both volumes, and this description includes many results in potential operators. Some techniques to find closed-form expressions in relevant applications are also presented. The second part deals with asymptotic results and presents a variety of applications, including random motion with different types of boundaries, the reliability of storage systems and solutions of partial differential equations with constant coefficients, using commutative algebra techniques. It also presents an alternative formulation to the Black-Scholes formula in finance, fading evolutions and telegraph processes, including jump telegraph processes and the estimation of the number of level crossings for telegraph processes.
The wild beauty of deserts has always been a source of fascination the world over. Mankind and Deserts 2 ? the second of three volumes ? focuses on water, its absence or indeed its extreme scarcity, as well as on the ways in which salts come to be formed in areas such as these. Aridity of the climate does not exclude rainfall, after which deserts flourish; wet mists, dew, exceptional events separated by years of total drought. Water flows into temporary and disorganized networks but, occasionally, large rivers cross the deserts, giving rise to vibrant civilizations: the Nile, Tigris and Euphrates, Niger, to name a few. Temporary or permanent lakes collect water in basins without outlet to the ocean, referred to as endorrheic basins, such as Lake Chad. This results in salt accumulation and evaporitic formations. A large variety of salts crystallize, in addition to halite, among which is potash. Halite ? common salt ? is an essential resource and its trade leads to the creation of salt caravans, used to exchange it with gold, even on a 1-1 weight basis, generating subsequent wealth. From ancient, almost mythical, exploration to modern scientific studies, deserts have come to be better known yet still hold great appeal. This book traces the history of their knowledge while providing a basis for understanding their features and the tools needed for their protection, in an ever-changing world.
