Each is introduced, with characteristics then discussed in detail. Finally, this book discusses future research directions to inspire further investigation in the field of vehicular channels from three different perspectives.

This book provides an introduction to classical celestial mechanics. It is based on lectures delivered by the authors over many years at both Padua University (MC) and V.N. Karazin Kharkiv National University (EB). The book aims to provide a mathematical description of the gravitational interaction of celestial bodies. The approach to the problem is purely formal. It allows the authors to write equations of motion and solve them to the greatest degree possible, either exactly or by approximate techniques, when there is no other way. The results obtained provide predictions that can be compared with the observations. Five chapters are supplemented by appendices that review certain mathematical tools, deepen some questions (so as not to interrupt the logic of the mainframe with heavy technicalities), give some examples, and provide an overview of special functions useful here, as well as in many other fields of physics. The authors also present the original investigation of torus potential. This book is aimed at senior undergraduate students of physics or astrophysics, as well as graduate students undertaking a master's degree or Ph.D.

This monograph explores the analysis and design of model-free optimal control systems based on reinforcement learning (RL) theory, presenting new methods that overcome recent challenges faced by RL.  New developments in the design of sensor data efficient RL algorithms are demonstrated that not only reduce the requirement of sensors by means of output feedback, but also ensure optimality and stability guarantees.  A variety of practical challenges are considered, including disturbance rejection, control constraints, and communication delays.  Ideas from game theory are incorporated to solve output feedback disturbance rejection problems, and the concepts of low gain feedback control are employed to develop RL controllers that achieve global stability under control constraints.Output Feedback Reinforcement Learning Control for Linear Systems will be a valuable reference for graduate students, control theorists working on optimal control systems, engineers, and applied mathematicians.

This book presents a compilation of lectures delivered at the São Paulo School of Advanced Sciences on Nonlinear Dynamics, categorized into four groups: parametric resonance, nonlinear modal analysis and model reduction, synchronization, and strongly nonlinear dynamics. Interwoven seamlessly, these groups cover a wide range of topics, from fundamental concepts to practical applications, catering to both introductory and advanced readers. The first group, consisting of chapters 1 and 2, serves as an introduction to the theory of parametric resonance and the dynamics of parametrically excited slender structures. Chapters 3, 4, and 5 form the second group, offering insights into normal forms, nonlinear normal modes, and nonlinear system identification. Chapters 6 and 7 delve into asynchronous modes of structural vibration and master-slave topologies for time signal distribution within synchronous systems, respectively, representing the third group. Finally, the last four chapters tackle the fourth group, exploring nonlinear dynamics of variable mass oscillators, advanced analytical methods for strong nonlinear vibration problems, chaos theory, and dynamic integrity from the perspectives of safety and design. This book harmoniously combines theoretical depth and practical relevance to provide a comprehensive understanding of nonlinear dynamics.

A dynamic system¿s performance and stability can be significantly impacted by regular disturbance. Techniques for disturbance rejection control aim to reduce the effects of disturbances while maintaining desired system behavior. This book explores the definition, objectives, mechanisms of control, and applications of disturbance rejection control. It also examines the theoretical underpinnings and practical implementations of various disturbance rejection control systems with a focus on the significance of flexibility and resilience. Disturbances will occur in any dynamic system and they can be brought on by both internal and external uncertainties. The performance of the system is significantly impacted by these interruptions, which can also cause it to depart from intended set points or trajectories. To mitigate the impact of disturbances and maintain desired system behavior, disturbance rejection control mechanisms are employed. This book provides a summary of disturbance rejection control and its importance in numerous applications.

Angriffe aus den eigenen Reihen durch sogenannte Innentäter sind für Unternehmen nur schwer zu erkennen. Unter Innentätern versteht man Personen, die in Unternehmen oder Organisationen vorsätzlich dolose Handlungen vornehmen. Ihnen fällt es aufgrund ihres Wissens über Interna leichter, etablierte Schutzmaßnahmen zu überwinden. Unternehmensinhaber trifft im Rahmen des mehrdeutigen Begriffs unternehmerischer Compliance auch eine Pflicht, in ihrem Betrieb für regelgetreues Verhalten der Beschäftigten zu sorgen. Es besteht insofern ein Spannungsverhältnis zwischen dem Recht auf informationelle Selbstbestimmung des Beschäftigten, welches durch das Datenschutzrecht geschützt wird, und der Pflicht des Arbeitgebers, in seinem Unternehmen für rechtskonformes Verhalten zu sorgen. Gegenstand des Buchs ist daher die Frage, welche Konsequenzen die Datenschutz-Grundverordnung sowie die Gesetzgebung auf nationalstaatlicher Ebene für den Beschäftigtendatenschutz im Allgemeinen sowie für die Umsetzung der neuen Anforderungen bei unternehmensinternen Compliance-Maßnahmen hat.

This monograph represents the outcome of research effort of the authors on scalable synchronization of large-scale multi-agent systems (MAS). Cooperative control of multi-agent systems has been growing in popularity and is highly interdisciplinary in recent years. The application of synchronization of MAS includes automobile systems, aerospace systems, multiple-satellite GPS, high-resolution satellite imagery, aircraft formations, highway traffic platooning, industrial process control with multiple processes, and more. Most of the proposed protocols in the literature for synchronization of MAS require some knowledge of the communication network such as bounds on the spectrum of the associated Laplacian matrix and the number of agents. These protocols suffer from scale fragility wherein stability properties are lost for large-scale networks or when the communication graph changes. In the past few years, the authors of this monograph have worked on developing scale-free protocol design for various cases of MAS problems. The key contribution of the monograph is to offer a scale-free design framework and provide scale-free protocols to achieve synchronization, delayed synchronization, and almost synchronization in the presence of input and communication delays, input saturation and external disturbances. The scale-free design framework solely is based on the knowledge of agent models and does not depend on information about the communication network such as the spectrum of the associated Laplacian matrix or size of the network. Drawing upon their extensive work in this area, the authors provide a thorough treatment of agents with higher-order dynamics, different classes of models for agents, and the underlying networks representing actions of the agents. The high technical level of their presentation and their rigorous mathematical approach make this monograph a timely and valuable resource that will fill a gap in the existing literature.

Reaction to breakdowns is more expensive, by many orders of magnitude, than prevention. This again became clear during the COVID-19 pandemic and is evinced in the sustainability crisis. The dynamics of living matter transcends deterministic reaction. Embodied in machines, determinism empowered the human being, providing the path to prosperity. However, in conjunction with reductionism, it does away with complexity, in which life is couched.The living is by necessity anticipatory. Awareness of the future means preserving life not in reaction to, but in anticipation of change. Living entities, from the simplest bacteria, to plants and insects, to human beings, are adaptive, goal-oriented, and capable of self-healing. Anticipatory actions are expressed through non-deterministic processes that unfold in concert with reactions. They engage the wholeness of life, including its interactions with the environment. Awareness of consequences, together with memory of the past, informs actions that reflect the creative nature of human beings. Redefining science¿and implicitly, medicine¿is not a negation of its past, but rather an affirmation of trust in explaining life¿s capacity to renew itself. As opposed to increasingly expensive medicine as a practice of repair, to prevent and to heal is to make life sustainable. The moment of truth can no longer be postponed. At stake is the future of humankind and even of life on planet Earth. Reductionist determinism informs the obsession with progress at any cost. Awareness of the fact that the human condition transcends that of the matter in which it is embodied explains, and indeed justifies, the call to Disrupt Science in its current state. The age of the digital machine, in particular of artificial intelligence, is one of opportunities that pale when compared to its inherent risks. The record of breakdowns (including so-called natural disasters), by now global in scale, is part of the empirical premise for the call for completing the Cartesian Revolution. A ¿Second Revolution in Science¿ could unleash humanity¿s remaking, free of surrendering to want. Science has the opportunity not only to measure everything¿life included¿and accumulate data and process it for its own sake, but also to realize its meaning. The future matters. Baruch Gorkin is celebrated internationally for exquisite typefaces and for books reflecting meaning-driven design.

This open access book gives a systematic introduction into the spectral theory of differential operators on metric graphs. Main focus is on the fundamental relations between the spectrum and the geometry of the underlying graph.The book has two central themes: the trace formula and inverse problems.The trace formula is relating the spectrum to the set of periodic orbits and is comparable to the celebrated Selberg and Chazarain-Duistermaat-Guillemin-Melrose trace formulas. Unexpectedly this formula allows one to construct non-trivial crystalline measures and Fourier quasicrystals solving one of the long-standing problems in Fourier analysis. The remarkable story of this mathematical odyssey is presented in the first part of the book.To solve the inverse problem for Schrödinger operators on metric graphs the magnetic boundary control method is introduced. Spectral data depending on the magnetic flux allow one to solve the inverse problem in full generality, this means to reconstruct not only the potential on a given graph, but also the underlying graph itself and the vertex conditions.The book provides an excellent example of recent studies where the interplay between different fields like operator theory, algebraic geometry and number theory, leads to unexpected and sound mathematical results. The book is thought as a graduate course book where every chapter is suitable for a separate lecture and includes problems for home studies. Numerous illuminating examples make it easier to understand new concepts and develop the necessary intuition for further studies.

This book concisely describes the technologies, human perception, and cognition issues relevant to autonomous vehicles. It also gives an insight in the changes bring about our future everyday lives.Autonomous vehicles are the future of the automobile industry. Automated driving (AD), also called self-driving, raises however several multiple questions, among them those of user safety and acceptation. Comprehensive HMI system design, with windshield display technics, will be necessary to deal with driving task delegations, bringing the use of VR or augmented reality (AR) technologies. In addition, the use of VR for all the vehicle interiors will progressively be proposed for entertainment, online business activities and for modified visual motion perception to alleviate car sickness, a form of motion sickness. Indeed, car sickness is already well known for many passengers, especially when reading or operating smartphones or other display devices. It is called to increase significantly with the introduction of autonomous vehicles where all users will be for long periods in various sitting positions. These two new trends, AD and VR, are already modifying our relationship with the world and the society. All together, they will change our way of life forever. The book will be of interest to professionals in the auto industry, researchers in automotive engineering and computer science and all those interested in the future of transport.

This is the first book to articulate how to address interlinkages among sustainable development goals (SDGs), which are keys to implementing those goals by 2030. At the heart of the book is a resilience approach to the enabling relevant systems, practices, and education and research. While SDGs are well known at different levels from local to global spheres, a major gap can be seen between goals and approaches, as approaches are lacking for addressing interlinkages among SDGs. The United Nations General Assembly in 2015 acknowledged interlinkages as being of crucial importance in ensuring the purpose of the goals. However, few actual approaches have been specified to address the interlinkages or interconnections at both the policy and practical levels. Thus, it is urgent to face the question of how to address the interlinkages by stakeholders¿not only policy communities and researchers but also practitioners and students, especially innovators who can go beyond existing boundaries. By highlighting that challenge, this book lays out a path for addressing interlinkages among SDGs by applying a resilience approach to the issues of a sustainable society. The resilience approach has been developed from combinations of different modes of thinking and practices, including the systems approach, systems and design thinking, and resilience thinking and practices. Based on this overarching approach, innovators seek out the relevance of that approach to their SDGs-related practices at the system, local, and educational levels. The book therefore serves as a guide to how the resilience approach can contribute to accelerating implementation of SDGs by 2030.
