Parity-time Symmetry and Its Applications (Springer Tracts in Modern Physics #280)
by Demetrios Christodoulides Jianke YangThis book offers a comprehensive review of the state-of-the-art theoretical and experimental advances in linear and nonlinear parity-time-symmetric systems in various physical disciplines, and surveys the emerging applications of parity-time (PT) symmetry. PT symmetry originates from quantum mechanics, where if the Schrodinger operator satisfies the PT symmetry, then its spectrum can be all real. This concept was later introduced into optics, Bose-Einstein condensates, metamaterials, electric circuits, acoustics, mechanical systems and many other fields, where a judicious balancing of gain and loss constitutes a PT-symmetric system. Even though these systems are dissipative, they exhibit many signature properties of conservative systems, which make them mathematically and physically intriguing. Important PT-symmetry applications have also emerged. This book describes the latest advances of PT symmetry in a wide range of physical areas, with contributions from the leading experts. It is intended for researchers and graduate students to enter this research frontier, or use it as a reference book.

Partial Differential Equations: An Introduction (Mathematical Engineering, Manufacturing, and Management Sciences)
by Nita H. Shah Mrudul Y. JaniDifferential equations play a noticeable role in engineering, physics, economics, and other disciplines. They permit us to model changing forms in both mathematical and physical problems. These equations are precisely used when a deterministic relation containing some continuously varying quantities and their rates of change in space and/or time is recognized or postulated. This book is intended to provide a straightforward introduction to the concept of partial differential equations. It provides a diversity of numerical examples framed to nurture the intellectual level of scholars. It includes enough examples to provide students with a clear concept and also offers short questions for comprehension. Construction of real-life problems is considered in the last chapter along with applications. Research scholars and students working in the fields of engineering, physics, and different branches of mathematics need to learn the concepts of partial differential equations to solve their problems. This book will serve their needs instead of having to use more complex books that contain more concepts than needed.

Partial Identification in Econometrics and Related Topics (Studies in Systems, Decision and Control #531)
by Vladik Kreinovich Nguyen Ngoc Thach Nguyen Duc Trung Doan Thanh HaThis book covers data processing techniques, with economic and financial application being the unifying theme. To make proper investments in economy, the authors need to have a good understanding of the future trends: how will demand change, how will prices change, etc. In general, in science, the usual way to make predictions is: to identify a model that best fits the current dynamics, and to use this model to predict the future behavior. In many practical situations—especially in economics—our past experiences are limited. As a result, the authors can only achieve a partial identification. It is therefore important to be able to make predictions based on such partially identified models—which is the main focus of this book. This book emphasizes partial identification techniques, but it also describes and uses other econometric techniques, ranging from more traditional statistical techniques to more innovative ones such as game-theoretic approach, interval techniques, and machine learning. Applications range from general analysis of GDP growth, stock market, and consumer prices to analysis of specific sectors of economics (credit and banking, energy, health, labor, tourism, international trade) to specific issues affecting economy such as ecology, national culture, government regulations, and the existence of shadow economy. This book shows what has been achieved, but even more important are remaining open problems. The authors hope that this book will: inspire practitioners to learn how to apply state-of-the-art techniques, especially techniques of optimal transport statistics, to economic and financial problems, andinspire researchers to further improve the existing techniques and to come up with new techniques for studying economic and financial phenomena. The authors want to thank all the authors for their contributions and all anonymous referees for their thorough analysis and helpful comments. The publication of this book—and organization of the conference at which these papers were presented—was supported: by the Ho Chi Minh University of Banking (HUB), Vietnam, and by the Vingroup Innovation Foundation (VINIF). The authors thank the leadership and staff of HUB and VINIF for providing crucial support.
Partial Moments in System Identification (Lecture Notes in Control and Information Sciences #494)
by Régis Ouvrard Thierry Poinot Jean-Claude TrigeassouThis book provides a complete round-up of developments concerned with the application of partial moments in system identification and data-driven modelling; it captures the essence of work carried out at the Laboratoire d'Informatique et d'Automatique pour les Systèmes for more than 40 years. The book begins with introductory material, describing both the mathematical tools associated with partial moments and reinitialized partial moments and an example demonstrating their use. The authors then proceed to show how these tools can be used for the identification of continuous-time linear models, discrete-time linear models, continuous-time linear state-space models, linear parameter-varying models and multidimensional models based on partial differential equations. The properties and performances of each of these approaches are presented. The analogy with algebraic approaches is proved, thus opening perspectives for extension to other fields. The text removes some long-standing limitations on the implementation of partial-moment-based tools in system identification. This book is of interest to researchers and postgraduates studying system identification, control theory, applied mathematics and computer science. It is also useful for engineers working on industrial applications of the parametric estimation of mathematical models.

Coverage includes concepts for partial module integration and corresponding communication architectures, floorplanning of the on-FPGA resources, physical implementation aspects starting from constraining primitive placement and routing all the way down to the bitstream required to configure the FPGA, and verification of reconfigurable systems.
A Partially Auxetic Metamaterial Inspired by the Maltese Cross (Elements in Emerging Theories and Technologies in Metamaterials)
by Teik-Cheng LimA partially-auxetic metamaterial is introduced, inspired by the Maltese cross. Each unit of this metamaterial consists of a pair of counter-rotating equal-armed crosses, which is interconnected to neighboring units via hinge rods and connecting rods. Based on linkage theory, the on-axes Poisson's ratio was established considering a two-fold symmetrical mechanism, while the (anti)tetrachiral mechanisms were identified for on-axes uniaxial compression. A shearing mechanism is suggested for pure shearing and diagonal loading of the metamaterial with square array. Results suggest that the approximated infinitesimal models are valid for the Poisson's ratio of the two-fold symmetrical and the (anti)tetrachiral mechanisms under on-axis tension and compression, respectively; however, the finite model is recommended for quantifying the Poisson's ratio under pure shear and off-axis loading. This metamaterial manifests microstructural trinity, in which three different loading modes result in three different groups of deformation mechanisms. Finally, suggestions are put forth for some unsolved predictive problems.
Partially Coherent Optical Transmission Theory in Optical Wireless Communication (Optical Wireless Communication Theory and Technology)
by Xizheng KeThis book introduces the theory and research methods of partially coherent optical, points out the significance of this study, analyzes the basic theories involved in partially coherent light, and explains the complete coherence of laser is not a necessary condition for good directivity, and partially spatially coherent optical sources can also produce the same far-field intensity distribution as lasers. This type of beam with good directivity but only partial spatial coherence is called a Gaussian Schell model beam, which can be used as a physical model to describe multimode lasers under certain conditions. This book is applicable to the large number of engineers and technicians involved in wireless optical communication and college teachers. It can also be used as a teaching material for graduate students and senior undergraduates in related fields.

They evaluate the strengths and weaknesses of these efforts and suggest specific ways to improve on future PAR efforts.
Participatory Design: Principles and Practices
by DOUGLAS SCHULER AND AKI NAMIOKAThe voices in this collection are primarily those of researchers and developers concerned with bringing knowledge of technological possibilities to bear on informed and effective system design. Their efforts are distinguished from many previous writings on system development by their central and abiding reliance on direct and continuous interaction with those who are the ultimate arbiters of system adequacy; namely, those who will use the technology in their everyday lives and work. A key issue throughout is the question of who does what to whom: whose interests are at stake, who initiates action and for what reason, who defines the problem and who decides that there is one. The papers presented follow in the footsteps of a small but growing international community of scholars and practitioners of participatory systems design. Many of the original European perspectives are represented here as well as some new and distinctively American approaches. The collection is characterized by a rich and diverse set of perspectives and experiences that, despite their differences, share a distinctive spirit and direction -- a more humane, creative, and effective relationship between those involved in technology's design and use, and between technology and the human activities that motivate the technology.
Participatory Design and Self-building in Shared Urban Open Spaces: Community Gardens And Casitas In New York City (Urban Agriculture Ser.)
by Carolin MeesThe book investigates the development of community gardens with self-built structures, which have existed as a shared public open space land use form in New York City’s low-come neighborhoods like the South Bronx since the 1970s. These gardens have continued to be part of the urban landscape until today, despite conflicting land use interests, changing residents groups and contradictory city planning. Both community gardens and self-built structures are created in a participatory design and self-built effort by urban residents and are an expression of the individual gardeners’ preferences, their cultural background and the decisions made by the managing residents’ group in regards to the needs of their neighborhood. Ultimately community gardens with self-built structures are an expression of the people’s will to commonly use this land for open and enclosed structures next to their homes in the city and need to be included in future urban planning.
Participatory Plant Breeding: Concept and Applications
by Atul Bhargava Shilpi SrivastavaPlant breeding has played a significant role in the development of human civilizations. Conventional plant breeding has significantly improved crop yield by genetically manipulating agronomically important traits. However, it has often been criticized for ignoring indigenous germplasm, failing to address the needs of the marginal and the poor farmers, and emphasizing selection for broad instead of local adaptation. Participatory plant breeding (PPB) is the process by which the producers and other stakeholders are actively involved in a plant-breeding programme, with opportunities to make decisions throughout. The Working Group on Participatory Plant Breeding (PPBwg) was established in 1996 under the framework of the Consultative Group on International Agricultural Research (CGIAR). Research in PPB can promote informed participation and trust in research among consumers and producers, and in recent years, PPB has had a significant impact on food production by quickly and cost-effectively producing improved crop varieties. At the same time, there has been significant research in the area. PPB offers significant advantages that are particularly relevant to developing countries where large investments in plant breeding have not led to increased production, especially in the marginal environments. In addition to the economic benefits, participatory research has a number of psychological, moral, and ethical benefits, which are the consequence of a progressive empowerment of the farming communities. PPB can empower groups such as women or less well-off farmers that are traditionally left out of the development process.This book explores the potential of PPB in the coming decades. The topic is more relevant since international breeding efforts for major crops are aimed at decentralizing local breeding methods to better incorporate the perspective of end users into the varietal development process. The first book incorporating the upcoming research on this novel breeding approach, it reviews the important tools and applications of PPB in an easy-to-read, succinct format, with illustrations to clarify these complex topics. It provides readers with a basic idea of participatory plant breeding as well as advances in the field and insights into the future to facilitate the successful integration of farmers into breeding programmes.This book is a valuable reference resource for agriculturists, agricultural advisers, policy makers, NGOs, post-doctoral students and scientists in agriculture, horticulture, forestry and botany.
Participatory Politics
by Elisabeth SoepAlthough they may disavow politics as such, civic-minded young people use every means and media at their disposal to carry out the basic tasks of citizenship. Through a mix of face-to-face and digital methods, they deliberate on important issues and debate with peers and powerbrokers, redefining some key dynamics that govern civic life in the process. In Participatory Politics, Elisabeth Soep examines the specific tactics used by young people as they experiment with civic engagement. Drawing on her scholarly research and on her work as a media producer and educator, Soep identifies five tactics that are part of effective, equitable participatory politics among young people: Pivot Your Public (mobilizing civic capacity within popular culture engagements); Create Content Worlds (using inventive and interactive storytelling that sparks sharing); Forage for Information in public data archives; Code Up (using computational thinking to design tools, platforms, and spaces for public good); and Hide and Seek (protecting privacy and information sources). After describing these tactics as they manifest themselves in a range of youth-driven activities -- from the runaway spread of the video Kony 2012 to community hackathons -- Soep discusses concrete ideas for cultivating the new literacies that will enable young people to participate in public life. She goes on to consider some risks associated with these participatory tactics, including simplification and sensationalism, and ways to avoid them, and concludes with implications for future research and practice.

Particle Accelerators, Colliders, and the Story of High Energy Physics
by Raghavan JayakumarThe Nordic mythological Cosmic Serpent, Ouroboros, is said to be coiled in the depths of the sea, surrounding the Earth with its tail in its mouth. In physics, this snake is a metaphor for the Universe, where the head, symbolizing the largest entity - the Cosmos - is one with the tail, symbolizing the smallest - the fundamental particle. Particle accelerators, colliders and detectors are built by physicists and engineers to uncover the nature of the Universe while discovering its building blocks. "Charming the Cosmic Snake" takes the readers through the science behind these experimental machines: the physics principles that each stage of the development of particle accelerators helped to reveal, and the particles they helped to discover. The book culminates with a description of the Large Hadron Collider, one of the world's largest and most complex machines operating in a 27-km circumference tunnel near Geneva. That collider may prove or disprove many of our basic theories about the nature of matter. The book provides the material honestly without misrepresenting the science for the sake of excitement or glossing over difficult notions. The principles behind each type of accelerator is made accessible to the undergraduate student and even to a lay reader with cartoons, illustrations and metaphors. Simultaneously, the book also caters to different levels of reader's background and provides additional materials for the more interested or diligent reader.

In
Particle Damping Technology Based Structural Control (Springer Tracts in Civil Engineering)
by Zheng Lu Sami F. Masri Xilin LuThis book presents a systematic introduction to particle damping technologies, which can be used to effectively mitigate seismic-induced and wind-induced vibration in various structures. Further, it offers comprehensive information on the latest research advances, e.g. a refined simulation model based on the discrete element method and a simplified simulation model based on equivalent principles. It then intensively studies the vibration attenuation effects of particle dampers subjected to different dynamic loads; in this context, the book proposes a new damping mechanism and “global’’ measures that can be used to evaluate damping performance.Moreover, the book uses the shaking table test and wind tunnel test to verify the proposed simulation methods, and their satisfactory damping performance is confirmed. To facilitate the practical engineering application of this technology, optimization design guidelines for particle impact dampers are also provided. In closing, the book offers a preliminary exploration of semi-active particle damping technology, which holds great potential for extension to other applications in which the primary system is subjected to non-stationary excitations.
