Buch. Condizione: Neu. Neuware - Written for students at upper-undergraduate and graduate levels, it is suitable for advanced physics courses on nonlinear physics. The book covers the fundamental properties of nonlinear waves, dealing with both theory and experiment. The aim is to emphasize established tools and introduce new methods underpinning important new developments in this field, especially as applied to solid-state materials. The updated edition has been extended to emphasize the importance of thermodynamics in a description of modulated crystals and contains new chapters on superconductivity that can be interpreted by the soliton mechanism. It is also updated to include new end-of-chapter problems.…

Buch. Condizione: Neu. Neuware - This book provides non-specialists with a basic understanding of the underlying concepts of quantum chemistry. It is both a text for second- or third-year undergraduates and a reference for researchers who need a quick introduction or refresher. All chemists and many biochemists, materials scientists, engineers, and physicists routinely use spectroscopic measurements and electronic structure computations in their work. This book is designed to help the novice user of these tools achieve a basic understanding of the underlying concepts of quantum chemistry. The emphasis is on explaining ideas rather than enumerating facts or presenting procedural details makes this an excellent foundational text. This new edition features extensive changes to increase clarity and to accommodate new material, including additional problems. a comprehensive list of resources and an introduction to computational quantum chemistry, while preserving the book's concise and accessible nature.Key Features - Updated and extended new edition - Accessible and concise introduction - Includes new additional problems with hints and solutions - Features an introduction to computational quantum chemistry, - Includes lists of print and online resources to support teaching.…

Buch. Condizione: Neu. Neuware - We are now living in the multimessenger era in which often weak and elusive astrophysical phenomena need to be studied using different and orthogonal probes and information carriers in order to be fully understood. This book is designed to give advanced undergraduate students a description of the most popular techniques and instrumentation employed in modern astrophysics. Focusing on electromagnetic radiation and its detection spanning from radio- to X-ray wavelengths, it gives a general description of astrophysical observables, such as flux, brightness, throughput, and magnitude. It describes general concepts about geometrical and physical optics at different wavelengths, in an astronomical context, including the concepts of lenses, mirrors, antennas, telescopes, the focal plane, angular resolution, the field of view, and the diffraction limit. The origin of noise and the extraction of a signal from it is also covered, including noise reduction techniques such as filtering, amplification, as well as cryogenic techniques. The theory of signals and the theorems related to digital electronics are also introduced. A set of student laboratory activities is included to illustrate the concepts covered in the book.Key Features - Provides a comprehensive introduction to modern astrophysical techniques and instrumentation - Covers astronomical optics, telescopes, noise, the theory of signals and digital electronics - Describes different receiving techniques such as coherent radiometers, semiconductor and superconductor thermal bolometers, charge-coupled devices (CCDs), and X-ray calorimeters - Includes a set of student laboratory activities to illustrate the concepts covered in the book.…

Buch. Condizione: Neu. Neuware - This book is intended to facilitate the testing of dynamic imaging systems to ensure safety of the systems. The aim is to discuss methods and techniques that may be used to commission and perform quality control (QC) measurements of dynamic x-ray imaging systems; the primary function of which is real time imaging to provide visualization of dynamic anatomical and other processes as they occur. Since dynamic imaging equipment is used for a wide range of clinical applications, the report includes a general description of the characteristics and operational aspects to assist the medical physicist with clinical setup and performance evaluation strategies. The automatic close rate control (ADRC) plays a significant role in determining the balance between patient dose and image quality, therefore the function and evaluation of ADRC plays a significant role in determining the balance between patient dose and image quality, therefore the function and evaluation of ADRC devices is discussed extensively. Key Features- Discuss methods and techniques that may be used to commission and perform quality control (QC) measurements of dynamic X-ray imaging systems.- Includes a general description of the characteristics and operational aspects to assist the medical physicist with clinical setup and performance evaluation strategies.- Function and evaluation of ADRC devices is discussed extensively.…

Buch. Condizione: Neu. Neuware - Quantum mechanics is perhaps the greatest scientific breakthrough ever achieved. It brought with it a seismic paradigm shift in our way of thinking about nature, and at the same time, it underpins most of the dramatic technological innovations of the modern era, as well as providing a profound lasting impact on our metaphysical conception of reality. This book provides oversight of many views on the interpretation of quantum physics and the wide philosophical debate that still embroils this subject. Following an introduction to quantum mechanics according to the Copenhagen interpretation and the many-worlds formalism, the reader is taken on a journey exploring the many physical results and theorems of quantum philosophy with an emphasis on quantum entanglement and Bell's theorem before proceeding to explore Hawking radiation and the corresponding information loss problem and its unitary resolution and the connection between spacetime geometry and quantum entanglement. The book then explores the issues of time and consciousness as both are intimately related to the foundation of quantum mechanics and concludes with a synthesis based on quantum dualism, i.e. the fact that the Copenhagen interpretation provides the local view of reality whereas the many-worlds formalism provides the manifold view and the two views are complementary, not contradictory. The breadth of coverage and renewed interest surrounding the interpretation of quantum physics will make the book essential reading for physicists working in or interested in the field of quantum physics and quantum reality, as well as those studying philosophy of science. Key Features Pedagogical exposition Accessible to students, built on graduate lecture courses Synthesis of interpretation ideas A fundamental topic of paramount importance with many unresolved issues.…

Buch. Condizione: Neu. Neuware - Gas sensors are traditionally used as part of an industrial safety system, but they are also increasingly found in a range of settings including home and vehicle security, ventilation systems and environmental monitoring. The technology also holds great promise in non-invasive medical applications and as an essential component in the future Internet of Things. Metal oxide semiconductors are the most common materials exploited for gas sensing. However, in recent years there have been significant advances in both fundamental research and industrial development of gas sensors using new and novel materials. This is being driven by efforts to achieve better selectivity, higher sensitivity and lower power consumption as gas sensors are finding more widespread applications. This book reviews the developments and applications of traditional and emerging materials for gas sensors. Each chapter considers a sensor material and discusses the mode of operation, intrinsic material properties, preparation, device construction and areas of application opened by the novel modes of action and properties of the sensing material. With coverage spanning n- and p-type metal oxides, graphene, 2D metal chalcogenides, carbon nanotubes, ionic liquids and conducting polymer composites. This up-to-date synthesis will provide invaluable reading for industrial and academic researchers and engineers developing and exploiting new materials for the increasingly diverse areas of applications for modern gas sensors.Key Features - Suitable to broad readership from advanced students to research scientists. - Interdisciplinary readership, from material scientists to sensor developers - Includes latest materials for sensor development. - Encompasses industrial and other applications.…
