Dynamical Systems with Applications Using Mathematica®
Dynamical Systems with Applications using Mathematica® provides an introduction to the theory of dynamical systems with the aid of the Mathematica computer algebra package. The book has a very hands-on approach and takes the reader from basic theory to recently published research material.
Dynamical Systems : Examples of Complex Behaviour
Our aim is to introduce, explain, and discuss the fundamental problems, ideas, concepts, results, and methods of the theory of dynamical systems and to show how they can be used in specific examples. Itis also important to find out when a certain dynamic behavior is stable under small perturbations, as well as to understand the various scenarios of instability. Finally, an essential aspect of a dynamic evolution is the transformation of some given initial state into some final or asymptotic state as time proceeds. The temporal evolution of a dynamical system maybe continuous or discrete, but it turns out that many of the concepts to be introduced a reuseful in either case.
Dynamical Oceanography
This textbook provides a mathematical introduction to the theory of large-scale ocean circulation and is accessible for readers with an elementary knowledge of mathematics and physics, including continuum mechanics and solution methods for ordinary differential equations. The book consists of four parts. Part I (chapters 1 - 4) is a very brief introduction to ocean circulation and the mathematical formulation of the governing equations of ocean flows. In addition, concepts are introduced that are necessary to describe and understand large-scale ocean currents. In part II (chapters 5 - 10), the theory of mid-latitude wind-driven ocean circulation is presented. Part III (chapters 11 - 12) focuses on the understanding of equatorial currents and El Nino. In the last part IV, chapters 13 - 16, the theory of planetary scale flows is presented, covering topics such as the thermocline problem, the Antarctic Circumpolar Current, the stability of the thermohaline circulation and the Arctic Ocean circulation.
Dynamic Population Models
The book is well organized and clearly written so that it is accessible to those with only a minimal knowledge of calculus. It begins with a review of fixed rate population models, from the basic life table to multistate stable populations. The process of convergence to stability is described, and the regularities underlying change in the size and composition of any population are explored. Techniques for estimating rates from multistate population distributions are presented, and new multi-age, multistate dynamic models are developed.
Drug delivery aspects : Expectations and realities of multifunctional drug delivery systems ; Vol.4 : Expectations and realities of multifunctional drug delivery systems
Reviews additional features of drug delivery systems, along with the standard formulation development, like preclinical testing, conversion into solid dosage forms, roles of excipients and polymers used on stability and sterile processing. There is a focus on formulation engineering and related large scale (GMP) manufacturing, regulatory, and functional aspects of drug delivery systems. A detailed discussion on biologics and vaccines gives insights to readers on new developments in this direction.
DNA Methylation : Basic Mechanisms
The structural and functional importance of the correct patterns of DNA methylation in all parts of a mammalian genome is not well understood. The stability, inheritability, and developmental flexibility of these patterns point to a major role that these patterns appear to play in determining structure and function of the genome.
Divorce in Europe : New Insights in Trends, Causes and Consequences of Relation Break-ups
This book collects the major discussions in divorce research in Europe. It starts with an understanding of divorce trends. Why was divorce increasing so rapidly throughout the US and Europe and do we see signs of a turn? Do cohabitation breakups influence divorce trends or is there a renewed stability on the partner market?
Dissipative Systems Analysis and Control : Theory and Applications
Dissipative Systems Analysis and Control (second edition) presents a fully revised and expanded treatment of dissipative systems theory, constituting a self-contained, advanced introduction for graduate students, researchers and practising engineers. It examines linear and nonlinear systems with examples of both in each chapter; some infinite-dimensional examples are also included. Throughout, emphasis is placed on the use of the dissipative properties of a system for the design of stable feedback control laws. The theory is substantiated by experimental results and by reference to its application in illustrative physical cases (Lagrangian and Hamiltonian systems and passivity-based and adaptive controllers are covered thoroughly).
Disruptive trends in automation technology
The industrial sector is being transformed by the convergence of information technology and operational technology. The latter is another name for automation technology and covers established systems such as supervisory control and data acquisition (SCADA), programmable logic controllers (PLC), fieldbuses, and automation and control systems. As this technology is connected to the Internet and 5G networks, some monitoring, control, and analytic functionalities are deployed to the edge or cloud, and researchers are challenged to ensure the security, dependability, real-time performance, and maintainability of the resulting systems. The big data that is accessible from these systems create opportunities for artificial intelligence applications that can further disrupt the established practices in the automation domain.
Disordered Materials : An Introduction
This self-contained text introduces the physics of structurally disordered condensed systems at the level of advanced undergraduate and graduate students. Among the topics are the geometry and symmetries of the structural units used as building blocks of extended structures, the various kinds of disorder, the phenomenology and the main theories of the glass transition, the structure of amorphous systems and the techniques to investigate it, the evolution of system's structure with its size (clusters) and the presence of orientational order in the absence of translational order (quasicrystals). In the second edition, the treatment of the mode coupling theory of the glass transition has been enlarged and connects now to a new section on collective excitations in disordered systems. Special attention has been devoted to nanometer-sized disordered systems, with emphasis on cluster-assembled materials. Questions of what governs the occurrence and stability of quasicrystals, the features of the amorphous to quasicrystal transformation and its reverse transition are discussed. The conditions leading to nano-quasicrystalline phases of technological interest are examined. Throughout the text relevant recent experimental and theoretical results are discussed so as to give readers insight into the currently most vibrant research topics.
Discrete-time Markov jump linear systems
Safety critical and high-integrity systems, such as industrial plants and economic systems, can be subject to abrupt changes - for instance, due to component or interconnection failure, sudden environment changes, etc. Combining probability and operator theory, Discrete-Time Markov Jump Linear Systems provides a unified and rigorous treatment of recent results for the control theory of discrete jump linear systems, which are used in these areas of application. The book is designed for experts in linear systems with Markov jump parameters, but is also of interest for specialists in stochastic control since it presents stochastic control problems for which an explicit solution is possible - making the book suitable for course use.
Differential Models : An Introduction with Mathcad
Differential equations are often used in mathematical models for technological processes or devices. However, the design of a differential mathematical model is crucial and difficult in engineering.
Differential Information Economies
One of the main problems in current economic theory is to write contracts which are Pareto optimal, incentive compatible, and also implementable as a perfect Bayesian equilibrium of a dynamic, noncooperative game. The question arises whether it is possible to provide Walrasian type or cooperative equilibrium concepts which have these properties. This volume contains original contributions on noncooperative and cooperative equilibrium notions in economies with differential information and provides answers to the above questions. Moreover, issues of stability, learning and continuity of alternative equilibria are also examined.
Device Applications of Nonlinear Dynamics
This edited book is devoted specifically to the applications of complex nonlinear dynamic phenomena to real systems and device applications. While in the past decades there has been significant progress in the theory of nonlinear phenomena under an assortment of system boundary conditions and preparations, there exist comparatively few devices that actually take this rich behavior into account. "Device Applications of Nonlinear Dynamics" applies and exploits this knowledge to make devices which operate more efficiently and cheaply, while affording the promise of much better performance. Given the current explosion of ideas in areas as diverse as molecular motors, nonlinear filtering theory, noise-enhanced propagation, stochastic resonance and networked systems, the time is right to integrate the progress of complex systems research into real devices.
Developing Organogel of CoEnzyme Q10
Coenzyme Q10 is a small lipophilic molecule composed of a benzoquinone ring and a hydrophobic isoprenoid tail and is present in all cell membranes. It is also an antioxidant. It plays a substantial role in energy production by acting as a mobile electron carrier in the electron transport chain. It has poor intestinal absorption and is prepared in topical forms. Organogel is a non-crystalline, non-glassy thermoreversible (thermoplastic) solid material and viscoelastic system can be regarded as a semi-solid preparation which has an immobilized external apolar phase, it is compatible with high molecular weight ingredients. The objective of present work is to prepare new dosage form with studying of different factors and conditions affecting preparation. Materials and methods: stearic acid and Flaxseed oil organogel was prepared by three methods and confirmed by quality assessment methods including: transparency, structure analysis, inverted tube test, kinetic of organogalation and stability test.
Developing burn ointment using seasam oil, tea tree oil, and,shea butter
The objective of our research project is to develop a burn healing ointment (Meburn) and to compare it with a well-known ointment, MEBO®. The second formula shows very good accelerated stability test results, its histology test was very promising, its ability to accelerate blood vessel formation in heat burns is significant, and, the rats that have been treated with (Meburn and Mebo®) started to get back to their normal weight after 2 weeks in approximate results. Results obtained from our study using rats as an animal model, showed that our proposed ointment (Meburn) has burn healing efficacy similar to Mebo® ointment.
Design of Hybrid Structures : Where Steel Profiles Meet Concrete
Focuses on design approaches for concrete structures reinforced in an unconventional way by steel profiles. It explains force transfer mechanisms of steel profiles and oncrete interfaces, and an analysis of the characteristics of hybrid structures, including slendercomponents. Several types of hybrid designs are addressed: walls and columns with several embedded steel profiles, connections strengthened by steel profiles between steel and composite or reinforced concrete components, including the specific case of shear keys connecting deep beams or flat slabs to columns. The transition zones in partly reinforced concrete and partly composite columns are also covered.
Desertification in the Mediterranean Region : A security issue ; Proceedings of the NATO Mediterranean Dialogue Workshop, held in Valencia, Spain, 2-5 December 2003
This book focuses on two basic concepts: security and desertification in the Mediterranean Region and their linkages. Desertification is recognized as a process of land degradation in arid, semi-arid, and dry sub-humid areas of the world that is the result of natural phenomena (e.g. climate variation) and anthropogenic factors. The outcome of this type of degradation has typically been considered to be either a reduction or a loss of both biological and economic productivity. The scope of the book includes the identification of the physical processes of desertification specific to both the north and south Mediterranean Region. Additionally, it specifically questions how changing environmental conditions may potentially reduce stability and peace in the world and thus affect "environmental security."
Dental gold alloys and gold nanoparticles for biomedical applications
Focuses on recent advances in dental gold alloys and gold nanoparticles (GNPs) for biomedical applications. Dental gold alloys combine several highly desirable mechanical properties, such as high strength, ductility, and elasticity, with an extremely robust chemical stability in the mouth.
Delft Pneumatic Bipeds
Walking is simple for most of us, but two-legged robots (bipeds) are often slow, complex, inefficient, heavy, and have robotic-looking motions. What makes human walking so graceful? Can this be replicated with human-like robots? Martijn Wisse and Richard Q. van der Linde provide a detailed description of their research on pneumatic biped robots at the Delft University of Technology, The Netherlands. The book covers the basic theory - passive dynamic walking - and explains the implementation of pneumatic McKibben muscles in a series of successful prototypes.
