Modeling of Physical Systems: Simulation and Control

by Raul G. Longoria Joseph J. Beaman

Introductory text on nonlinear and continuous-time dynamic systems using bond graph methodology to enable readers to develop and apply physical system models Through an integrated and uniform approach to system modeling, analysis, and control, Modeling of Physical Systems uses realistic examples to link empirical, analytical, and numerical approaches and provide readers with the essential foundation needed to move towards more advanced topics in systems engineering. Rather than use only a linear modeling methodology, this book also incorporates nonlinear modeling approaches. The authors approach the topic using bond graph methodology, a well-known and highly effective method for the modeling and analysis of multi-energy domain systems at the physical level. With a strong focus on fundamentals, this book begins by reviewing core topics which engineering students will have been exposed to in their first two years of study. It then expands into introducing systematic model development using a bond graph approach. Later chapters expand on the fundamental understanding of systems, with insights regarding how to make decisions on what to model and how much complexity is needed for a particular problem. Written by two professors with nearly a century of combined research and industry experience, Modeling of Physical Systems explores topics including: Basic Kirchoff systems, covering mechanical translation and rotation, electrical, hydraulic, and thermal systems, and ideal couplersA complete introduction to bond graph methods and their application to practical engineering system modelingComputer-based analysis and simulation, covering algebraic analysis of system equation and semi-analytical analysis for linear system responseMultiport fields, distributed systems and transmission elements, covering heat and magnetism power lines and wave propagation modeling with W- and H-LinesSignal and power in measurement and control, covering derivative control and effect of feedback Modeling of Physical Systems is an essential learning resource for mechanical, mechatronics, and aerospace engineering students at the graduate and senior graduate level. The text is also valuable for professional engineers and researchers, controls engineers, and computer scientists seeking an understanding of engineering system modeling.

Modeling the Electrochemo-poromechanics of Ionic Polymer Metal Composites and Cell Clusters (Springer Theses)

by Alessandro Leronni

This book presents a novel continuum finite deformation framework addressing the complex interactions among electrostatics, species transport, and mechanics in solid networks immersed in a fluid phase of solvent and ions. Grounded on cutting-edge multiphysics theories for soft active materials, the proposed model is primarily applied to ionic polymer metal composites (IPMCs). First, the influence of shear deformation on the IPMC response is analyzed through semi-analytical solutions obtained via the method of matched asymptotic expansions. Second, the novel electrochemo-poromechanical theory is used to predict the curvature relaxation and electric discharge that are observed in IPMC actuation and sensing, respectively, under a sustained stimulus. This newly formulated theory is, in turn, applied to biological cell clusters. Here, important mechanical considerations are integrated into classical bioelectrical models, thus offering novel insights into the interplay of mechanical and electrical signaling in the coordination of developmental processes.

Modeling the Fate of Chemicals in Products (Springer Theses)

by Li Li

This thesis provides a novel methodological basis for mechanistically understanding the dynamics of chemicals in products (CiPs) in the anthroposphere and physical environment and establishes a modeling continuum from production of a chemical to its concentrations in various environmental compartments. Using this framework, the thesis investigates how CiPs are transported and transformed and how they accumulate in the global environment. Furthermore, it identifies the measures needed to minimize their adverse effects on the environment and human society. It serves as an invaluable, interdisciplinary reference resource for industrial ecologists, environmental chemists and decision-makers involved in environmentally sound management of CiPs and associated waste.

Modeling the Health Risks of Climate Change: Workshop Summary

by Kellyn Betts

Climate change poses risks to human health and well-being through shifting weather patterns, increases in frequency and intensity of heat waves and other extreme weather events, rising sea levels, ocean acidification, and other environmental effects. Those risks occur against a backdrop of changing socioeconomic conditions, medical technology, population demographics, environmental conditions, and other factors that are important in determining health. Models of health risks that reflect how health determinants and climate changes vary in time and space are needed so that we can inform adaptation efforts and reduce or prevent adverse health effects. Robust health risk models could also help to inform national and international discussions about climate policies and the economic consequences of action and inaction. Interest in resolving some of the challenges facing health effects modelers and health scientists led the National Research Council's Standing Committee on Emerging Science for Environmental Health Decisions to hold a workshop on November 3-4, 2014, in Washington, DC, to explore new approaches to modeling the human health risks of climate change. Throughout the workshop, the discussions highlighted examples of current application of models, research gaps, lessons learned, and potential next steps to improve modeling of health risks associated with climate change. "Modeling the Health Risks of Climate Change" summarizes the presentation and discussion of the workshop.

Modeling the Interplay Between Human Behavior and the Spread of Infectious Diseases

by Alberto D'Onofrio Piero Manfredi

This volume summarizes the state-of-the-art in the fast growing research area of modeling the influence of information-driven human behavior on the spread and control of infectious diseases. In particular, it features the two main and inter-related "core" topics: behavioral changes in response to global threats, for example, pandemic influenza, and the pseudo-rational opposition to vaccines. In order to make realistic predictions, modelers need to go beyond classical mathematical epidemiology to take these dynamic effects into account. With contributions from experts in this field, the book fills a void in the literature. It goes beyond classical texts, yet preserves the rationale of many of them by sticking to the underlying biology without compromising on scientific rigor. Epidemiologists, theoretical biologists, biophysicists, applied mathematicians, and PhD students will benefit from this book. However, it is also written for Public Health professionals interested in understanding models, and to advanced undergraduate students, since it only requires a working knowledge of mathematical epidemiology.

Modeling, Analysis, Control and Removal of Oil and Hydrocarbon Spills (Earth and Environmental Sciences Library)

by Tatiana Chaplina

A large number of scientific works are devoted to the study and modeling of accidental oil spills. However, there is no single approach to the description of processes and a generally accepted system of models. An additional fundamental difficulty is the impossibility of conducting full-fledged full-scale experimental studies, which makes it difficult to verify the adequacy and accuracy of oil spill models. Our book is devoted to the problems of experimental investigation and theoretical description of spills, as well as the practical removal of various petroleum products from the water surface and ice. It provides an overview of the most well-known theoretical models of the process of spreading oil stains on the water surface. Also, in the relevant sections, an original spreading model based on an energy approach is proposed and analyzed. The results of new experimental studies of the dynamics of the process for various hydrocarbons on water, including variations in its temperatureand salinity, are presented. In the following chapters, a theoretical description of oil spreading on the upper and lower surfaces of floating ice is proposed, modeling phenomena in the Arctic and subarctic zones of the world ocean. New experimental data on the spreading of petroleum products on the ice surface are presented. The final part provides a brief overview of the existing most used and promising methods for removing of hydrocarbons from the water surface. New original constructive solutions to this problem are proposed, the technical characteristics of which have received theoretical justification and experimental confirmation.

Modellierungsverfahren für die Konzeption von komplexen Systemen in der Fernsehproduktion: Operationalisierung des Systems Engineering für die digitale Transformation im Fernsehen

by Christiane Janusch

Die Herstellungsprozesse in der Fernsehproduktion sind von einer unüberschaubaren Anzahl unterschiedlicher Varianten geprägt. Verschiedene Produktionsformen, wie beispielsweise die Aktualität, Live-Events oder Fiktionales Programm, erfordern ein vielfältiges Zusammenspiel der Funktionsbereiche eines Fernsehproduktionsunternehmens. Für die Optimierung der Herstellungsprozesse müssen redaktionell steuernde, administrativ begleitende und technisch ausführende Prozesse in übergreifend vernetzten, integrierten Produktionssystemen eng miteinander verknüpft werden. Vor dem Hintergrund dieser Komplexität bedarf es einer Gesamtsicht auf alle an der Produktion beteiligten Funktionsbereiche und deren Einbindung in den Herstellungsprozess. Es wird ein umfassendes Modellierungsverfahren vorgestellt, das in der Lage ist, sowohl die Gesamtbetrachtung zu fördern als auch Detailbetrachtungen vorzunehmen. Darüber hinaus wird die Anwendung der Methodik anhand von Praxisbeispielen erläutert. Es ist ein Vorschlag, den wissenschaftlichen Ansatz des Systems Engineering im Hinblick auf Problemstellungen in der Fernsehproduktion zu operationalisieren und den kontinuierlichen Optimierungsprozess zu unterstützen.

Modelling Approaches to Understand Salinity Variations in a Highly Dynamic Tidal River: The Case of the Shatt al-Arab River (IHE Delft PhD Thesis Series)

by Ali Dinar Abdullah

This book reports the first systematic monitoring and modelling study on water availability, water quality and seawater intrusion of the Shatt al-Arab River (SAR) on the border of Iraq and Iran, where causes and concentration levels of salinity have not yet been fully understood, let alone addressed, leading to conflicting perceptions of its origin (external or internal), the natural conditions and the practices that can explain the current critical conditions. Current scientific knowledge on the SAR salinity problem is deficient, partially due to the complex and dynamic interaction between marine and terrestrial salinity sources, including return flows by water users of the different water sectors in the Euphrates and Tigris rivers upstream of the SAR. The development of a new series of monitoring stations and various modelling approaches helped to better understand the interactions between these different sources. The comprehensive and detailed dataset formed the basis for a validated analytical model that can predict the extent of seawater relative to other salinity sources in an estuary, and for a hydrodynamic model that can predict salinity changes. The adaptability of the models to changing conditions makes them directly applicable by water managers. The procedure can be applied to other comparable systems.

Modelling Atomic Arrangements in Multicomponent Alloys: A Perturbative, First-Principles-Based Approach (Springer Series in Materials Science #346)

by Christopher D. Woodgate

This book provides a comprehensive overview of a computationally efficient approach for modelling the phase behaviour of multicomponent alloys from first principles, describing both short- and long-range atomic ordering tendencies. The study of multicomponent alloy systems, which combine three or more base elements in near-equal ratios, has garnered significant attention in materials science due to the potential for the creation of novel materials with superior properties for a variety of applications. High-entropy alloys, which contain four or more base elements, have emerged as a particularly fascinating subset of these systems, demonstrating extraordinary strength and fracture resistance, among other desirable properties. The book presents a novel modelling approach for studying the phase behaviour of these systems, which is based on a perturbative analysis of the internal energy of the disordered alloy as evaluated within the Korringa–Kohn–Rostoker (KKR) formulation of density functional theory (DFT), using the coherent potential approximation (CPA) to average over chemical disorder. Application of a Landau-type theory to an approximate form of the Gibbs free energy enables direct inference of chemical disorder/order transitions. In addition, the perturbative analysis facilitates extraction of atom-atom effective pair interactions for further atomistic simulations. The connection between the arrangement of atoms in a material and its magnetic properties is also studied. By outlining and applying the proposed modelling techniques to several systems of interest, this book serves as a valuable resource for materials scientists, physicists, and chemists alike, seeking to understand and develop new alloy systems with enhanced materials properties.
