State Estimation and Stabilization of Nonlinear Systems: Theory and Applications (Studies in Systems, Decision and Control #491)
by Mohamed Ali Hammami Omar Naifar Abdellatif Ben MakhloufThis book presents the separation principle which is also known as the principle of separation of estimation and control and states that, under certain assumptions, the problem of designing an optimal feedback controller for a stochastic system can be solved by designing an optimal observer for the system's state, which feeds into an optimal deterministic controller for the system. Thus, the problem may be divided into two halves, which simplifies its design. In the context of deterministic linear systems, the first instance of this principle is that if a stable observer and stable state feedback are built for a linear time-invariant system (LTI system hereafter), then the combined observer and feedback are stable. The separation principle does not true for nonlinear systems in general. Another instance of the separation principle occurs in the context of linear stochastic systems, namely that an optimum state feedback controller intended to minimize a quadratic cost is optimal for the stochastic control problem with output measurements. The ideal solution consists of a Kalman filter and a linear-quadratic regulator when both process and observation noise are Gaussian. The term for this is linear-quadratic-Gaussian control. More generally, given acceptable conditions and when the noise is a martingale (with potential leaps), a separation principle, also known as the separation principle in stochastic control, applies when the noise is a martingale (with possible jumps).
State Estimation for Nonlinear Continuous–Discrete Stochastic Systems: Numerical Aspects and Implementation Issues (Studies in Systems, Decision and Control #539)
by Gennady Yu. Kulikov Maria V. KulikovaThis book addresses the problem of accurate state estimation in nonlinear continuous-time stochastic models with additive noise and discrete measurements. Its main focus is on numerical aspects of computation of the expectation and covariance in Kalman-like filters rather than on statistical properties determining a model of the system state. Nevertheless, it provides the sound theoretical background and covers all contemporary state estimation techniques beginning at the celebrated Kalman filter, including its versions extended to nonlinear stochastic models, and till the most advanced universal Gaussian filters with deterministically sampled mean and covariance. In particular, the authors demonstrate that, when applying such filtering procedures to stochastic models with strong nonlinearities, the use of adaptive ordinary differential equation solvers with automatic local and global error control facilities allows the discretization error—and consequently the state estimation error—to be reduced considerably. For achieving that, the variable-stepsize methods with automatic error regulation and stepsize selection mechanisms are applied to treating moment differential equations arisen. The implemented discretization error reduction makes the self-adaptive nonlinear Gaussian filtering algorithms more suitable for application and leads to the novel notion of accurate state estimation. The book also discusses accurate state estimation in mathematical models with sparse measurements. Of special interest in this regard, it provides a means for treating stiff stochastic systems, which often encountered in applied science and engineering, being exemplified by the Van der Pol oscillator in electrical engineering and the Oregonator model of chemical kinetics. Square-root implementations of all Kalman-like filters considered and explored in this book for state estimation in Ill-conditioned continuous–discrete stochastic systems attract the authors’ particular attention. This book covers both theoretical and applied aspects of numerical integration methods, including the concepts of approximation, convergence, stiffness as well as of local and global errors, suitably for applied scientists and engineers. Such methods serve as a basis for the development of accurate continuous–discrete extended, unscented, cubature and many other Kalman filtering algorithms, including the universal Gaussian methods with deterministically sampled expectation and covariance as well as their mixed-type versions. The state estimation procedures in this book are presented in the fashion of complete pseudo-codes, which are ready for implementation and use in MATLAB® or in any other computation platform. These are examined numerically and shown to outperform traditional variants of the Kalman-like filters in practical prediction/filtering tasks, including state estimations of stiff and/or ill-conditioned continuous–discrete nonlinear stochastic systems.
State Estimation for Robotics
by Timothy D. BarfootA key aspect of robotics today is estimating the state, such as position and orientation, of a robot as it moves through the world. Most robots and autonomous vehicles depend on noisy data from sensors such as cameras or laser rangefinders to navigate in a three-dimensional world. This book presents common sensor models and practical advice on how to carry out state estimation for rotations and other state variables. It covers both classical state estimation methods such as the Kalman filter, as well as important modern topics such as batch estimation, the Bayes filter, sigmapoint and particle filters, robust estimation for outlier rejection, and continuous-time trajectory estimation and its connection to Gaussian-process regression. The methods are demonstrated in the context of important applications such as point-cloud alignment, pose-graph relaxation, bundle adjustment, and simultaneous localization and mapping. Students and practitioners of robotics alike will find this a valuable resource.

State of the Art in Deep Geothermal Energy in Europe: With Focus on Direct Heating (SpringerBriefs in Earth System Sciences)
by Johanna Fink Elisa Heim Norbert KlitzschSince nearly 50 % of Europe's energy demand is in the heating and cooling sector, it is expected that geothermal energy will play an important role in the transition to a decarbonized energy system. However, deep geothermal energy is currently harvested mainly from areas with very favorable geothermal conditions. As these areas are geographically limited, the use of geothermal energy in less favorable regions is essential for unleashing the full potential of geothermal energy, since they make up the majority of the total geothermal potential in Central Europe. Motivated by the growing interest in deep geothermal energy among, e.g., energy companies and communities, this text reviews the state of the art in deep geothermal energy with focus on direct heating in geothermally less favorable regions. It provides an overview of technologies used to generate heat from the deep underground and discusses main technical and non-technical risks associated with deep geothermal projects. The text addresses readers with an interest in geothermal energy but does not require a background in geoscience or engineering sciences. It is suitable as textbook for Geothermal Energy courses for undergraduate students from different disciplines.
State-Level Changes in Energy Intensity and Their National Implications
by Mark A. Bernstein Sam Loeb David S. Loughran Katya FonkychThe 2001 National Energy Policy calls for continued reductions in energy intensity (energy consumption per dollar of gross economic output). This study was part of an effort to identify state-level factors that may contribute to efficient energy use nationwide. The authors examined changes in energy intensity in 48 states and in the states' energy-consuming sectors from 1977 through 1999. Some factors that may explain differences in states' energy intensity are energy prices, new construction, capacity utilization, population, climate, tech innovations, and government energy policies.

State-of-the-Art in Skin Grafting (Biomedical Materials for Multi-functional Applications)
by Vivek Gupta Arnab Chanda Shubham GuptaThis book discusses the different skin grafting methods, latest trends in graft designing, and its relationship with the burn injuries. An introduction to several conventional and modern skin grafting methods and how crucial the innovation is for recovery of large burns will be presented. The technologies involved in the development of skin grafts incisions, and study of their effect on the mechanical properties and systematically modified skin graft patterns, will be covered at length. The development of skin grafts using conventional, auxetic, and hierarchical patterns through computational and experimental frameworks will be discussed in detail. Also, the role of skin graft patterns on the mechanical stresses, expansion ratio or meshing ratio, will be presented. Additionally, the role of degree of burn, size of burn, and region of burn will be discussed, and its generalizability will be covered in detail. Finally, the challenges with the existing skin graft meshers and latest development in this niche area will be highlighted. This book is anticipated to serve as a key reference for medical and research professionals working in the skin grafting domain as well as the product manufacturing industries. For example, skin grafting plays an important role to cure the serious burn injuries. Current innovative skin graft patterns which cover higher area compared to traditional skin graft patterns are anticipated to help in surgery and faster recovery of larger burnt areas. Also, the current skin graft mesher, which is used to develop traditional skin grafts, cannot produce claimed expansions clinically. This book helps design novel mesher devices to reduce the difference between actual and claimed expansions clinically and increase the skin graft coverage area to recover burn sites with lesser available skin. This book is equally useful for students of medical practices, manufacturing engineering, and design engineering.
State-of-the-Art of Millimeter-Wave Silicon Technology (Lecture Notes in Electrical Engineering #945)
by Saurabh Sinha Jaco du PreezThis book examines the critical differences between current and next-generation Si technologies (CMOS, BiCMOS and SiC) and technology platforms (e.g. system-on-chip) in mm-wave wireless applications.

States of Nature: Science, Agriculture, and Environment in the Spanish Caribbean, 1760-1940
by Stuart George MccookThe process of nation-building in Latin America transformed the relations between the state, the economy, and nature. <P><P>Between 1760 and 1940, the economies of most countries in the Spanish Caribbean came to depend heavily on the export of plant products, such as coffee, tobacco, and sugar. After the mid-nineteenth century, this model of export-led economic growth also became a central tenet of liberal projects of nation-building. As international competition grew and commodity prices fell over this period, Latin American growers strove to remain competitive by increasing agricultural production. By the turn of the twentieth century, their pursuit of export-led growth had generated severe environmental problems, including soil exhaustion, erosion, and epidemic outbreaks of crop diseases and pests.

Static Compensators (STATCOMs) in Power Systems
by Sumedha Rajakaruna Farhad Shahnia Arindam GhoshA static compensator (STATCOM), also known as static synchronous compensator, is a member of the flexible alternating current transmission system (FACTS) devices. It is a power-electronics based regulating device which is composed of a voltage source converter (VSC) and is shunt-connected to alternating current electricity transmission and distribution networks. The voltage source is created from a DC capacitor and the STATCOM can exchange reactive power with the network. It can also supply some active power to the network, if a DC source of power is connected across the capacitor. A STATCOM is usually installed in the electric networks with poor power factor or poor voltage regulation to improve these problems. In addition, it is used to improve the voltage stability of a network. This book covers STATCOMs from different aspects. Different converter topologies, output filters and modulation techniques utilized within STATCOMs are reviewed. Mathematical modeling of STATCOM is presented in detail and different STATCOM control strategies and algorithms are discussed. Modified load flow calculations for a power system in the presence of STATCOMs are presented. Several applications of STATCOMs in transmission and distribution networks are discussed in different examples and optimization techniques for defining the optimal location and ratings of the STATCOMs in power systems are reviewed. Finally, the performance of the network protection scheme in the presence of STATCOMs is described. This book will be an excellent resource for postgraduate students and researchers interested in grasping the knowledge on STATCOMs.

Static and Dynamic Buckling of Thin-Walled Plate Structures
by Tomasz KubiakThis monograph deals with buckling and postbuckling behavior of thin plates and thin-walled structures with flat wall subjected to static and dynamic load. The investigations are carried out in elastic range. The basic assumption here is the thin plate theory. This method is used to determination the buckling load and postbuckling analysis of thin-walled structures subjected to static and dynamic load. The book introduces two methods for static and dynamic buckling investigation which allow for a wider understanding of the phenomenon. Two different methods also can allow uncoupling of the phenomena occurring at the same time and attempt to estimate their impact on the final result. A general mathematical model, adopted in proposed analytical-numerical method, enables the consideration of all types of stability loss i.e.local, global and interactive forms of buckling. The applied numerical-numerical method includes adjacent of walls, shear-lag phenomenon and a deplanation of cross-sections.
