Book SynopsisAn exploration of the technical, economic, and energy-saving aspects of the design, modeling, and operation of non-conventional cooling and heating systems Cooling and heating can collectively constitute one of the largest sources of energy consumption in a modern building, with attendant costs and sustainability concerns. As the global climate changes and temperature extremes produce demand for even greater energy consumption, energy-efficient methods for cooling interior spaces have become more important than ever. Our sustainable future demands non-conventional methods for cooling and thermal storage which can meet the demands of a changing climate and an efficient, renewable power grid. Advancements in Non-Conventional Cooling and Thermal Storage Strategies offers a detailed introduction to the latest cutting-edge space conditioning technologies for buildings. Beginning with an overview of activated carbon-based adsorbents and their potential heating a

Book SynopsisThe main objective of this book is to provide to mechanical scientists and engineers the kinetic modeling tools necessary for predicting the damage state of organic composite matrices submitted to hydrolytic and oxidative ageing. These tools are derived from the degradation mechanisms and their validity is successfully checked from many experimental data. They can be interfaced with existing or under development computer codes for predicting the lifetime of composite structures. Particular attention is paid to the relationships between damage state and use properties in view of defining structural end-of-life criteria. For this purpose the book is divided into three main parts. The first one is devoted to the presentation of the common aspects to all types of chemical degradation processes. Emphasis is put on specific aspects of composite structures, such as the role of interphase/interface or the anisotropy of reagent diffusion, but also on current issues in the field of material ageing such as the study of multiphysics couplings. The second part is focused on humid ageing. Physical processes linked to plasticization and swelling, are distinguished from chemical processes in particular from the matrix hydrolysis and its resulting damages at the microstructural scale (osmotic cracking, blistering, etc.). The third part concerns thermal ageing. The ultimate objective is to predict the consequences of thermal oxidation on thermomechanical properties of organic composite matrices, in particular on their glass transition temperature and elastic and fracture properties. In each part, the kinetic approach is illustrated by several practical examples.Table of ContentsIntroduction 1) Common aspects in composite ageing 2) Humid ageing 3) Thermal ageing Conclusion

Book SynopsisThis second edition with four additional chapters presents the physical principles and solution techniques for transient propagation in fluid mechanics and hydraulics. The application domains vary including contaminant transport with or without sorption, the motion of immiscible hydrocarbons in aquifers, pipe transients, open channel and shallow water flow, and compressible gas dynamics. The mathematical formulation is covered from the angle of conservation laws, with an emphasis on multidimensional problems and discontinuous flows, such as steep fronts and shock waves. Finite difference-, finite volume- and finite element-based numerical methods (including discontinuous Galerkin techniques) are covered and applied to various physical fields. Additional chapters include the treatment of geometric source terms, as well as direct and adjoint sensitivity modeling for hyperbolic conservation laws. A concluding chapter is devoted to practical recommendations to the modeler. Application exercises with on-line solutions are proposed at the end of the chapters.Trade Review"However, for practitioners this book can give an insight into physical phenomena of wave propagation in fluids."

Book SynopsisCharge and Energy Transfer Dynamics in Molecular Systems Comprehensive resource offering knowledge on charge and energy transfer dynamics in molecular systems and nanostructures Charge and Energy Transfer Dynamics in Molecular Systems provides a unified description of different charge and energy transfer phenomena in molecular systems with emphasis on the theory, bridging the regimes of coherent and dissipative dynamics and thus presenting classic rate theories as well as modern treatments of ultrafast phenomena. Starting from microscopic models, the common features of the different transfer processes are highlighted, along with applications ranging from vibrational energy flow in large polyatomic molecules, the motion of protons in solution, up to the concerted dynamics of electronic and nuclear degrees of freedom in molecules and molecular aggregates. The newly revised and updated Fourth Edition contains a more detailed coverage of recent developments in density matrix theory, mixed quantum-classical methods for dynamics simulations, and a substantially expanded treatment of time-resolved spectroscopy. The book is written in an easy-to-follow style, including detailed mathematical derivations, thus making even complex concepts understandable and applicable. Charge and Energy Transfer Dynamics in Molecular Systems includes information on: Electronic and vibrational molecular states, covering molecular Schrödinger equation, Born—Oppenheimer separation and approximation, Hartree-Fock equations and other electronic structure methods Dynamics of isolated and open quantum systems, covering multidimensional wave packet dynamics, and different variants of density operator equations Interaction of molecular systems with radiation fields, covering linear and nonlinear optical response using the correlation function approach Intramolecular electronic transitions, covering optical transition and internal conversion processes Transfer processes of electrons, protons, and electronic excitation energy Providing in-depth coverage of the subject, Charge and Energy Transfer Dynamics in Molecular Systems is an essential resource for anyone working on timely problems of energy and charge transfer in physics, chemistry and biophysics as well as for all engaged in nanoscience and organic electronics.Table of ContentsPreface to the Fourth Edition xiii Preface to the Third Edition xv Preface to the Second Edition xvii Preface to the First Edition xix 1

Book SynopsisFür alle, die es genauer wissen wollen: Band 1 der Neuauflage des unschlagbar präzisen Ansorge/Oberle-Lehrwerks zur Mathematik in den Ingenieur- und Naturwissenschaften In sämtlichen Ingenieurwissenschaften, insbesondere im Maschinenbau, im Bauingenieurwesen und in der Elektrotechnik, ist Mathematik unverzichtbar bei der Beschreibung, Modellierung und Lösung ingenieurwissenschaftlicher Probleme. Für Studierende dieser Fächer ist es daher unabdingbar, sich detailliert mit der Mathematik auseinanderzusetzen und Wissen zu erwerben, das über die reine Anwendung von "Kochrezepten" hinausgeht. Der vorliegende Band 1 des vollständig überarbeiteten und erweiterten Lehrwerks "Mathematik in den Ingenieur- und Naturwissenschaften" gibt eine Einführung in die Lineare Algebra und analytische Geometrie sowie die Differential- und Integralrechnung einer Variablen.

Book SynopsisAdvanced Chemical Process Control Bridge the gap between theory and practice with this accessible guide Process control is an area of study which seeks to optimize industrial processes, applying different strategies and technologies as required to navigate the variety of processes and their many potential challenges. Though the body of chemical process control theory is robust, it is only in recent decades that it has been effectively integrated with industrial practice to form a flexible toolkit. The need for a guide to this integration of theory and practice has therefore never been more urgent. Advanced Chemical Process Control meets this need, making advanced chemical process control accessible and useful to chemical engineers with little grounding in the theoretical principles of the subject. It provides a basic introduction to the background and mathematics of control theory, before turning to the implementation of control principles in industrial contexts. The result is a bridge between the insights of control theory and the needs of engineers in plants, factories, research facilities, and beyond. Advanced Chemical Process Control readers will also find: Detailed overview of Control Performance Monitoring (CPM), Model Predictive Control (MPC), and more Discussion of the cost benefit analysis of improved control in particular jobs Authored by a leading international expert on chemical process control Advanced Chemical Process Control is essential for chemical and process engineers looking to develop a working knowledge of process control, as well as for students and graduates entering the chemical process control field.Table of ContentsPreface xvii Acknowledgments xxi Acronyms xxiii

Book SynopsisVibration Testing: Theory and Practice, Second Edition is a step-by-step guide that shows how to obtain meaningful experimental results via the proper use of modern instrumentation, vibration exciters, and signal-processing equipment, with particular emphasis on how different types of signals are processed with a frequency analyzer. Thoroughly updated, this new edition covers all basic concepts and principles underlying dynamic testing, explains how current instruments and methods operate within the dynamic environment, and describes their behavior in a number of commonly encountered field and laboratory test situations.Trade Review"…is a good foundational text for engineers concerned with component vibration testing as it might relate to failure analysis, qualification testing, reliability testing, and machinery diagnostics. The book is well written and makes the presented concepts easy to understand. I recommend it both as an introduction to laboratory testing techniques for the relative novice and as a reference for experienced practitioners in the field."
