While the two-body problem (reduced after separation of the centre of mass motion to a one-body problem at zero energy) is a well-studied subject, the literature on many-body threshold problems is sparse. However, the authors' analysis covers for example the system of three particles interacting by Coulomb potentials and restricted to a small energy region to the right of a fixed nonzero two-body eigenvalue. In general, the authors address the question: How do scattering quantities for the many-body atomic and molecular models behave within the limit when the total energy approaches a fixed two-cluster threshold? This includes mapping properties and singularities of the limiting scattering matrix, asymptotics of the total scattering cross section, and absence of transmission from one channel to another in the small inter-cluster kinetic energy region. The authors' principal tools are the Feshbach-Grushin dimension reduction method and spectral analysis based on a certain Mourre estimate. Additional topics of independent interest are the limiting absorption principle, micro-local resolvent estimates, Rellich- and Sommerfeld-type theorems and asymptotics of the limiting resolvents at thresholds. The mathematical physics field under study is very rich, and there are many open problems, several of them stated explicitly in the book for the interested reader. ![]() Free Download Specialty Crops for Climate Change Adaptation: Strategies for Enhanced Food Security by Using Machine Learning and Artificial Intelligence by Chandrasekar Vuppalapati English | EPUB (True) | 2023 | 836 Pages | ISBN : 3031383982 | 181 MB Specialty crops are defined as fruits and vegetables, tree nuts, dried fruits, horticulture, and nursery crops including floriculture. The value of specialty crop production in the United States accounted for 18.44 % of the $433.569 billion in agriculture cash receipts collected in 2021. In 2020, that ratio was 21.47% of the $363.464 billion. Specialty crops are gaining increasing attention across nation as demonstrated in the 2018 farm bill (Agricultural Act of the 2018 Farm Bill (P.L. 115-334)) with the increased number of provisions addressing specialty crop issues, reflecting their growing role in the global economy. ![]() Free Download Spatial Observation of Giant Panda Habitat: Techniques and Methods by Xinyuan Wang , Jing Zhen , Qingkai Meng English | EPUB (True) | 2023 | 391 Pages | ISBN : 9811987939 | 149.7 MB This book evaluates the past, present, and future habitat suitability of giant pandas based on spatial observation technology involving optical remote sensing, microwave remote sensing, and LiDAR to discover the mysterious ecological environment of giant panda habitat. Considering the problems faced by the world natural heritage site protection, it takes the world natural heritage site "Sichuan Giant Panda Sanctuaries - Wolong, Mt Siguniang and Jiajin Mountains" as the research area, exemplifies systematically the various techniques and methodologies of spatial information technology for monitoring, evaluation, and prediction of rare and endangered species habitats, and provides scientific suggestions for sustainable development of giant panda habitat based on a series of comprehensive case analysis at Wolong national nature reserve and Ya'an prefecture, Sichuan province, China. The book serves both as a textbook in the field of natural heritage protection, remote sensing, and GIS application, as well as a reference for managing natural heritage sites.

![]() Free Download Spatial Encounters and Togetherness in the Metropolis: The Metrobuses of Istanbul by Özlem Cihan English | PDF EPUB (True) | 2024 | 300 Pages | ISBN : 3031600894 | 6.8 MB This book analyzes Istanbul's bus rapid transit, the metrobus, as an encountering space to unfold the perception and practice of togetherness. Based on field research with regular metrobus passengers, the book presents a layered analysis between everyday life, everyday mobility, and togetherness to emphasize the metropolitan impact on the socio-spatial experience and subjectification. By articulating Lefebvrian social space in a metropolitan context, the book discusses that Istanbul's spatially and temporally framed everydayness leads inhabitants to the need for bus rapid transit. On the other hand, the need for the metrobus produces transit modes of experience in regulars' socio-spatial relation and subjectification. As a result, encountering and being with the unfamiliar and diverse others undertake the framed typologies of the first two layers and produce a dissolving essence in the idea and practice of togetherness in Istanbul. ![]() Free Download Space Rescue: Ensuring the Safety of Manned Spacecraft by David J.

Bland English | PDF | 1961 | 107 Pages | ISBN : 0710043538 | 5.1 MB THIS book is an introduction both to Laplace's equation and its solutions and to a general method of treating partial differential equations. Chapter 1 discusses vector fields and shows how Laplace's equation arises for steady fields which are irrotational and solenoidal. In the second chapter the method of separation of variables is introduced and used to reduce each partial differential equation, Laplace's equa tion in different co-ordinate systems, to three ordinary differential equations. Chapters 3 and 5 are concerned with the solutions of two of these ordinary differential equations, which lead to treatments of Bessel functions and Legendre polynomials. Chapters 4 and 6 show how such solutions are combined to solve particular problems. This general method of approach has been adopted because it can be applied to other scalar and vector fields arising in the physi cal sciences; special techniques applicable only to the solu tions of Laplace's equation have been omitted. In particular generating functions have been relegated to exercises. After mastering the content of this book, the reader will have methods at his disposal to enable him to look for solutions of other partial differential equations. The author would like to thank Dr. W. Ledermann for his criticism of the first draft of this book. D. R. BLAND The University, Sussex. v Contents Preface page v 1.
