Theoretical Study on Graphite and Lithium Metal as Anode Materials for Next-Generation Rechargeable Batteries (Springer Theses)
by Gabin YoonThis thesis describes in-depth theoretical efforts to understand the reaction mechanism of graphite and lithium metal as anodes for next-generation rechargeable batteries. The first part deals with Na intercalation chemistry in graphite, whose understanding is crucial for utilizing graphite as an anode for Na-ion batteries. The author demonstrates that Na ion intercalation in graphite is thermodynamically unstable because of the unfavorable Na-graphene interaction. To address this issue, the inclusion of screening moieties, such as solvents, is suggested and proven to enable reversible Na-solvent cointercalation in graphite. Furthermore, the author provides the correlation between the intercalation behavior and the properties of solvents, suggesting a general strategy to tailor the electrochemical intercalation chemistry. The second part addresses the Li dendrite growth issue, which is preventing practical application of Li metal anodes. A continuum mechanics study considering various experimental conditions reveals the origins of irregular growth of Li metal. The findings provide crucial clues for developing effective counter strategies to control the Li metal growth, which will advance the application of high-energy-density Li metal anodes.
Theoretical Thermotics: Transformation Thermotics and Extended Theories for Thermal Metamaterials
by Ji-Ping HuangThis book focuses on theoretical thermotics, the theory of transformation thermotics and its extended theories for the active control of macroscopic thermal phenomena of artificial systems, which is in sharp contrast to classical thermodynamics comprising the four thermodynamic laws for the passive description of macroscopic thermal phenomena of natural systems. The book covers the basic concepts and mathematical methods, which are necessary to understand thermal problems extensively investigated in physics, but also in other disciplines of engineering and materials. The analyses rely on models solved by analytical techniques accompanied with computer simulations and laboratory experiments. This book serves both as a reference work for senior researchers and a study text for zero beginners.
Theoretical Treatment of Electron Emission and Related Phenomena
by Benjamin Seznec Tiberiu Minea Philippe Dessante Philippe Teste Gilles MaynardThis book introduces readers to the physics governing electron emission under high voltages and temperatures, and highlights recent modeling and numerical developments for describing these phenomena. It begins with a brief introduction, presenting several applications that have driven electron emission research in the last few decades. The authors summarize the most relevant theories including the physics of thermo-field electron emission and the main characteristic parameters. Based on these theories, they subsequently describe numerical multi-physics models and discuss the main findings on the effect of space charges, emitter geometry, pulse duration, etc.Beyond the well-known photoelectric effect, the book reviews recent advanced theories on photon-metal interaction. Distinct phenomena occur when picosecond and femtosecond lasers are used to irradiate a surface. Their consequences on metal electron dynamics and heating are presented and discussed, leading to various emission regimes – in and out of equilibrium. In closing, the book reviews the effects of electron emission on high-voltage operation in vacuum, especially breakdown and conditioning, as the most common examples. The book offers a uniquely valuable resource for graduate and PhD students whose work involves electron emission, high-voltage holding, laser irradiation of surfaces, vacuum or discharge breakdown, but also for academic researchers and professionals in the field of accelerators and solid state physics with an interest in this highly topical area.

Theories and Methods for Minimizing Cadmium Pollution in Crops: Case Studies on Water Spinach
by Zhongyi Yang Chuntao He Junliang XinThe cadmium (Cd) contamination has raised increasingly global concern on food safety. The book was composed to bring comprehensive and valuable thoughts about the food safety management against heavy metal contamination. In this book, current status of cadmium contamination in agricultural soils and crops is systematically summarized. In order to reduce the risk of Cd pollution in crops, Cd pollution-safe cultivar (Cd-PSC) strategy, i.e. identifying, breeding and applying the cultivars with particularly low Cd accumulation capacity in edible parts even when grown in Cd contaminated soil, is proposed as a most effective, low-cost and environmental-friendly method for minimizing Cd pollution in crops. To describe the framework of the Cd-PSC strategy, a series research results on water spinach (Ipomoea aquatica Forsk) are summarized as a typical case. The latest findings about the Cd-PSCs of water spinach, including cultivar variation in shoot Cd accumulation, identification and verification of low- and high-Cd accumulating cultivars, stability of Cd accumulation capacity at the cultivar level, biochemical and molecular mechanisms of the cultivar-dependent Cd uptake, transfer and accumulation, breeding methods for improving Cd-PSCs, and so on, have been covered. This book will provide valuable theoretical and practical understandings for controlling Cd pollution in crops grown on agricultural soils with known or unknown risk of Cd contamination.

Theories and Simulations of Complex Social Systems
by Vahid Dabbaghian Vijay Kumar MagoResearch into social systems is challenging due to their complex nature. Traditional methods of analysis are often difficult to apply effectively as theories evolve over time. This can be due to a lack of appropriate data, or too much uncertainty. It can also be the result of problems which are not yet understood well enough in the general sense so that they can be classified, and an appropriate solution quickly identified. Simulation is one tool that deals well with these challenges, fits in well with the deductive process, and is useful for testing theory. This field is still relatively new, and much of the work is necessarily innovative, although it builds upon a rich and varied foundation. There are a number of existing modelling paradigms being applied to complex social systems research. Additionally, new methods and measures are being devised through the process of conducting research. We expect that readers will enjoy the collection of high quality research works from new and accomplished researchers.

Theorising Institutional Change: The Impact of the European Integration Process on the Development of Space Activities in Europe (Springer Theses)
by Nina-Louisa RemussThe book provides a structural analysis of the European space effort from an institute change perspective. It analyzes the EU-ESA inter-institutional relationship, gives an overview of the development of space policy in Europe, and advances the debate about the impact of the European integration process on existing institutional actors. While European Space collaboration was initially developed outside the competences of the European Union (EU) with space programmes being carried out almost exclusively under the framework of European Space Agency (ESA) and national agencies, the EU has gained “shared competences” (Art. 2, TFEU) in space policy following the adoption of the Lisbon Treaty. Currently the EU and ESA work together under a Framework Agreement. In 2016, the EU Commission has published a Communication entitled “European Space Policy” (ESP). Even though ESA’s Member States have agreed to keep ESA as an intergovernmental organisation during the ESA Ministerial Council of 2014, the discussion about ESA becoming part of the EU framework continues. The EU’s ambitions for leadership in European space policy raise question concerning the future of ESA. The study of institutions lies at the heart of political sciences. Strikingly the theoretic framework qualifying institutional change and making it comparable leaves room for more concrete and testable dimensions of institutional change.
Theorising Personalised Education
by Barbara Garrick Donna Pendergast David GeelanThis book examines the theoretical underpinning of the concept of personalised education and explores the question: What is personalised education in the contemporary higher education sector and how is it implemented? A broad, sophisticated definition of personalised learning has the potential to serve as a basis for more effective educational practices. The term 'personalised education' is, and continues to be, one with a variety of definitions. The authors' definition both incorporates earlier concepts of personalised education and critically reassesses them. The book then adds a further dimension: personalised instruction in electronically mediated environments, where the goal is to achieve learning towards mastery individually with the help of differentiated and individualised electronic learning platforms. This book assesses the various arguments concerning personalised education, examining each through the lens of educational theory and pedagogy and subsequently positing a number of qualitative characteristics of personalised education that have the potential to influence policy and practices in the higher education sector.
Theorizing Transboundary Waters in International Relations (Springer Water)
by Kinga Szálkai Máté SzalaiThis book is the first collection of state-of-the-art research projects analyzing water conflict and cooperation with an explicitly theoretical point of view. Its fourteen chapters offer a comprehensive and up-to-date overview on how the application of various theoretical perspectives can support the work of scholars and practitioners in mitigating water conflict and developing cooperation.The volume starts out from a literature review on the theorization of transboundary waters in International Relations, which prepares the ground for the demonstration of the latest approaches of scholars currently working on this field. The discussion of their findings is divided into four main sections. The first section deals with reflections and critiques on the grand theories of International Relations, proposing new and more nuanced frameworks for understanding and managing transboundary water relations by going beyond the traditional assumptions. The second section focuses on the catalysts and barriers of cooperation, applying theoretical frameworks which reveal the consequences of the dynamics in power relations and institutional frameworks. The third section investigates into the perspectives at the intersections of theory and practice related to the most practical field within the scope of the volume: water diplomacy. The fourth section introduces new perspectives to provide specific entry points for understanding and managing water conflict and cooperation.Overall, the work intends to demonstrate that the theorization of transboundary waters can significantly contribute to the deeper understanding and the more efficient management of water conflicts and cooperation from several aspects.The authors come from diverse backgrounds, and their individual careers are often related to the intersections of theory and practice in the field of transboundary water management. Their expertise covers water issues from all around the globe, which is reflected in the range of the analyzed case studies. The diversity of the experts involved, their backgrounds, their perspectives, the applied theories, and the analyzed cases was an important priority for the editors.
Theory, Analysis and Design of RF Interferometric Sensors
by Seoktae Kim Cam NguyenTheory, Analysis and Design of RF Interferometric Sensors presents the theory, analysis and design of RF interferometric sensors. RF interferometric sensors are attractive for various sensing applications that require every fine resolution and accuracy as well as fast speed. The book also presents two millimeter-wave interferometric sensors realized using RF integrated circuits. The developed millimeter-wave homodyne sensor shows sub-millimeter resolution in the order of 0.05 mm without correction for the non-linear phase response of the sensor's quadrature mixer. The designed millimeter-wave double-channel homodyne sensor provides a resolution of only 0.01 mm, or 1/840th of the operating wavelength, and can inherently suppress the non-linearity of the sensor's quadrature mixer. The experimental results of displacement and velocity measurement are presented as a way to demonstrate the sensing ability of the RF interferometry and to illustrate its many possible applications in sensing. The book is succinct, yet the material is very much self-contained, enabling readers with an undergraduate background in electrical engineering or physics with some experiences or graduate courses in RF circuits to understand easily.

Theory and Application of Acoustic Sources Using Complex Analysis: Complex Acoustic Sources, Green’s Functions and Half-Space Problems, Acoustic Radiation and Scattering Using Equivalent Source and Boundary Element Methods
by Martin Ochmann Rafael PiscoyaThis book highlights the mathematical and physical properties of acoustical sources with singularities located in the complex plane and presents the application of such special elements to solve acoustical radiation and scattering problems. Sources whose origin lies in the complex plane are also solutions of the wave equation but possess different radiating properties as their counterparts with real positions. Such mathematical constructions are known in the fields of optics and electrodynamics, but they are not common in acoustical research. The objective of the book is to introduce this concept to acousticians and motivate them to engage themselves in further research and application of complex sources. Such sources are particularly useful to formulate Green’s functions and related equivalent source and boundary element methods in half-spaces.
Theory and Application of Hydraulic Modeling: Interaction between Wave and Ground Motion
by Taro ArikawaThis edited volume from Japan’s Research Subcommittee on Methodology for Dealing with Geomaterials in Hydraulic Model Experiments presents readers with a state-of-the-art overview of experimental and computational methods used to address similarity scaling incompatibilities present in fluid–sediment flows.Readers will gain an understanding of complex phenomena in the boundary fields of hydraulics and geotechnical engineering. Chapter contributors focus on the phenomena that are affected by the interactions between fluid wave and ground in a complex field, which for many years have been challenging to process and model. In addition to describing the implementation of model tests and the concept of the law of similarity, this book contrasts these phenomena with the laws of similarity, describes models and numeral analysis methods, and explains important considerations using experimental case studies. Each chapter is written by leading researchers in Japan who are members of the Research Subcommittee on Methodology for Dealing with Geomaterials in Hydraulic Model Experiments. The chapters are closely linked but are written so that each can be read individually. Readers will be able to apply this knowledge to their work and to create models that more accurately simulate the interactions between wave and ground, allowing them to better understand these phenomena and devise more appropriate strategies for defense and so on when necessary.This collection provides information that can be used by young researchers and post-graduate students in the boundary fields of hydraulics and geotechnical engineering who aim at becoming civil engineers, and it will be of particular value to practicing engineers of all experience levels who must regularly analyze complex interactions between fluids and ground.
Theory and Application of Liapunov's Direct Method (Dover Books on Mathematics)
by Wolfgang HahnThe groundbreaking work of Russian mathematician A. M. Liapunov (1857–1918) on the stability of dynamical systems was overlooked for decades because of political turmoil. During the Cold War, when it was discovered that his method was applicable to the stability of aerospace guidance systems, interest in his research was rekindled. It has remained high ever since.This monograph on both the theory and applications of Liapunov's direct method reflects the work of a period when the theory had been studied seriously for some time and reached a degree of completeness and sophistication. It remains of interest to applied mathematicians in many areas. Topics include applications of the stability theorems to concrete problems, the converse of the main theorems, Liapunov functions with certain properties of rate of change, the sensitivity of the stability behavior to perturbations, the critical cases, and generalizations of the concept of stability.
