What Is Energy?: An Answer Based on the Evolution of a Concept (History of Physics)
By Ricardo Lopes Coelho. 2024
This book provides a solution to the problem with the energy concept. This problem manifests itself in the fact that…
physicists clearly diverge regarding the question of what energy is. Some define it but others state that we do not know what it is. Although this is a problem for physicists who need to explain the concept, it is not a problem for physics that can be solved by laboratory means. Penetrating into the origin of the notion of energy, this book offers a clear idea of what was discovered and what was invented to interpret the findings.Following the development of the concept, it provides an explanation of the trends in contemporary textbooks. The author's repetition, in his "History and Philosophy of Physics Laboratory", of Joule’s famous experiment – the paddle wheel experiment – with a calorimeter as originally used by Joule and with a calorimeter as proposed in textbooks, is presented, yielding new insight into the phenomenon. Thus, science teachers and students will benefit from reading the book as well as historians, philosophers, students of the history and philosophy of science, and all who are interested in knowing about what it is that we call energy.Critical Infrastructure Protection in the Light of the Armed Conflicts (Advanced Sciences and Technologies for Security Applications)

This book summarizes the latest findings in critical infrastructure protection and related research areas. Armed conflicts and wars are now…
closer to Europe than at any time in the last several decades, and the protection of critical infrastructures has gained new prominence. This situation has also revealed the vulnerability of critical infrastructure and the importance of its protection. The development of technologies, cybertechnologies, and digitalization in all aspects of our daily lives implies new security challenges in critical infrastructure protection and security science and this book addresses the four main dimensions of critical infrastructure protection: 1. Physical protection 2. Cybersecurity 3. Political security 4. Individual security The issue of physical security has accompanied humanity since its birth. Nowadays, this issue has become even more important due to technological advances, as this is the security area that people physically experience—physical protection, including protection against explosions and ballistic attacks, but also defense of objects and guaranteeing transportation security. Cyberspace represents the fifth domain of warfare and a central security question in our age. The base of cyberspace defense is high-quality hardware and expert support. With our lives increasingly digital, cybersecurity's core elements include safety awareness and informatics. Political security, the third dimension, is shaped by diverse political ideologies influencing economies, societies, and other aspects of life. This book explores topics such as migration policies, defense against terrorism, national and international security, and public safety.The fourth dimension, individual security, spans healthcare, food safety, energy supplies, and economic security. Each chapter of this book emphasizes security, focusing on Central Europe while addressing global concerns. Authored by researchers, experts, and scholars, this book is invaluable for Ph.D. students, professionals, and educators worldwide.The fourth dimension, individual security, spans healthcare, food safety, energy supplies, and economic security.

and soil water. Soil however is a complex entity with interacting biological, physical and chemical processes that are rarely modelled in its entirety. Additionally, for the sake of simplicity various soil properties are considered constants whereas in reality they are not. Soil as we observe it is the resultant of many processes driven by varying boundary conditions such as climate and organisms including men. This is not different when we study global change, thus modelling soil development under global change overlaps with modelling soil formation. This book gives an overview of what such model should entail, with ample descriptions to use SoilGen, a simulattion model to study pedogenesis.Wider die Borniertheit und den Chauvinismus – mit Paul K. Feyerabend durch absurde Zeiten
By Wolfgang Frindte. 2024
This book presents a novel comprehensive thermodynamic framework, suitable for the design of new macroscopic models, as well as the…
combination of existing models. Our goal is to popularize thermodynamics for model designers. The example series of models includes very classic solid and fluid models, such as Newtonian, viscoplastic and viscoelastic materials, but also new heat effects and original combinations of existing models. The aim of the new proposed framework is to allow a clear and easy development of constitutive equations that automatically satisfy the second principle. Instead of writing directly constitutive relations, model designers are encouraged to first specify the energy. This book is primarily intended for graduate students and researchers in applied mathematics, engineering sciences, computational mechanics and physics. The reader is assumed to be familiar with classical mechanics, together with matrix and tensors algebra.This book discusses acoustic waves in five chapters. Chapter 1 reviews the general properties of waves. Chapter 2 presents the…
acoustic waves in fluid and solids, including the wave equations in the respective media. Chapter 3 discusses the propagation of audible acoustic waves in the air. The discussion includes analyses of speech and music we hear in the time and frequency domains. Chapter 4 discusses the propagation of acoustic waves in solids. Unlike in the air, sound waves take complicated forms in solids; they can be both in longitudinal and transverse modes, and mode conversions can occur upon reflection. Although these behaviors make the analysis difficult, we can apply them to engineering problems. Chapter 5 describes the transduction of acoustic signals. It presents acoustic transmitters and sensors along with their operation principles. Finally, Chapter 6 presents several techniques used in engineering. It is also useful to consider applying acoustic and optical techniques to engineering problems.Industrial Color Physics (Springer Series in Optical Sciences #154)
By Georg A. Klein. 2010
Colors arise only in the brain, normally originating from electromagnetic waves from the outside world. This book is based on…
courses given by the author in the Department of Colors, Paints and Plastics at the University of Applied Sciences in Stuttgart and continued at the University of Applied Sciences in Esslingen, Germany. The development of color physics in industry began in the middle of the 19th century with the large-scale manufacturing of natural colors. Since that time, a great variety of new, especially synthetic, colorants have been produced in order to meet increasing demands for non-self-luminous colors with regard to color applications. The rapid progress in color physics and accompanying applications over the last three decades are the reasons for this work. Here, the fundamentals of color physics are outlined and the most important recent developments and applications in the color industry are discussed. 1 In comparison to the ?rst German edition, all chapters of the book have been revised and expanded with regard to effect pigments. After the introd- tory chapter, the optical fundamentals of absorbing and effect colorants are discussed. The exceptional spectral and colorimetric properties of effect p- ments are detailed in combination with further characterizing parameters. Color spaces are presented as well as the ef?ciency of recent color difference f- mulas. In addition to the normal spectral measuring methods for absorbing colorants, modi?ed procedures for effect colorations are outlined.Manifold Learning: Model Reduction in Engineering (SpringerBriefs in Computer Science)
By David Ryckelynck, Fabien Casenave, Nissrine Akkari. 2024
This Open Access book reviews recent theoretical and numerical developments in nonlinear model order reduction in continuum mechanics, being addressed…
to Master and PhD students, as well as to researchers, lecturers and instructors. The aim of the authors is to provide tools for a better understanding and implement reduced order models by using: physics-based models, synthetic data forecast by these models, experimental data and deep learning algorithms. The book involves a survey of key methods of model order reduction applied to model-based engineering and digital twining, by learning linear or nonlinear latent spaces.Projection-based reduced order models are the projection of mechanical equations on a latent space that have been learnt from both synthetic data and experimental data. Various descriptions and representations of structured data for model reduction are presented in the applications and survey chapters. Image-based digital twins are developed in a reduced setting. Reduced order models of as-manufactured components predict the mechanical effects of shape variations. A similar workflow is extended to multiphysics or coupled problems, with high dimensional input fields. Practical techniques are proposed for data augmentation and also for hyper-reduction, which is a key point to speed up projection-based model order reduction of finite element models.The book gives access to python libraries available on gitlab.com, which have been developed as part of the research program [FUI-25] MORDICUS funded by the French government. Similarly to deep learning for computer vision, deep learning for model order reduction circumvents the need to design parametric problems prior reducing models. Such an approach is highly relevant for image-base modelling or multiphysics modelling.Dieses Buch bietet einzigartige und umfassende konzeptionelle Erklärungen der Quantenfeldtheorie und des Standardmodells der Teilchenphysik.

Wellen im Vakuum existieren? Wie können solche Wellen Teilcheneigenschaften wie z. B. Trägheit haben? Was verbirgt sich hinter dem Begriff der virtuellen Teilchen? Warum und wie üben die Teilchen Kräfte aufeinander aus? Und nicht zuletzt: Was sind überhaupt Kräfte? Dies sind einige der zentralen Fragen, auf die die Quantenfeldtheorie und das Standardmodell der Teilchenphysik faszinierende Antworten geben. Leider sind diese Theorien hochgradig mathematisch, so dass die meisten Menschen - sogar viele Wissenschaftler - nicht in der Lage sind, ihre Bedeutung vollständig zu erfassen. Dieses Buch entwirrt diese Theorien auf eine konzeptionelle, nicht-mathematische Weise, indem es mehr als 190 Abbildungen und ausführliche Erklärungen verwendet und dadurch großartige Einsichten vermittelt, die in der populärwissenschaftlichen Literatur nicht zu finden sind. Diese vollständig überarbeitete und erweiterte zweite Auflage bietet bemerkenswerte Einblicke in den Übergang von der Quanten- zur klassischen Welt unter Verwendung des Konzepts der Quantendekohärenz, wobei auch der "Kollaps der Wellenfunktion", der Tunneleffekt und das Quantencomputing erklärt werden.Chaotic Dynamics in Planetary Systems (Springer Praxis Books)

Network (ANN) in seismology, earthquake early warning system, waveform inversion, moment tensor analysis, receiver function analysis, earthquake prediction, and earthquake early warning system applications. To minimize the losses due to an earthquake, it is better to understand the source properties, medium characteristics, site condition, and amplitude of a probable earthquake at a particular site. The evolutions of earthquake source models make it possible to understand the source dynamics. However, analysis of the source using a single-domain method does not provide a better understanding of the source dynamics. Therefore, this book combines methods from the earthquake spectrum to waveform inversion and joint inversion. The book also discusses earthquake prediction methods and their reliability around the globe, and techniques of simulation viz. stochastic, empirical, semi-empirical, and hybrid, along with their limitations and application. Seismology is an interdisciplinary subject. Therefore, the information presented in the book will appeal to a wider readership from students, teachers, researchers, planners engaged in developmental work, and people concerned with earthquake awareness.Recent Trends in Cancer Therapeutics: Plasmonic Photothermal-Based Multimodal Cancer Therapy (Materials Horizons: From Nature to Nanomaterials)
