Taschenbuch. Zustand: Neu. Neuware -This volume is dedicated to 'Mechanics in Architecture', that is, the science of structural mechanics, including the behaviour of structures, internal forces, and deformation, as well as the development of new structural systems to resist thrusts as a result of new architectural forms. It is a field of enquiry that examines a particular aspect of the relationships between architecture and the mathematical sciences. Some of the papers in this issue were presented at the Nexus 2006 conference during a special session dedicated to mechanics. Other research papers focus on an eighteenth-century Belgian pyramid, aspects of 'fractal' architecture, and properties of a family of irrational values. The issue also includes a description and evaluation of a university-level course in architecture and mathematics, Rachel Fletcher's Geometer's Angle column, and book reviews.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 228 pp. Englisch.

Taschenbuch. Zustand: Neu. Neuware -Understanding, modeling and prediction of mesoscale processes in the atmosphere, ocean and environmental systems, have gained importance in the last decade or so. This is because of the availability of more sophisticated observational systems, provided by technological innovations and more realistic simulations using advanced dynamical models.This volume contains many original findings on mesoscale processes in atmospheric and oceanic systems through mathematical modeling, numerical simulations and field experiments. These scientific papers examine and provide the latest developments on a range of topics that include tropical cyclones/hurricanes, mesoscale variability and modeling, seasonal monsoons and land surface processes including atmospheric boundary layer. This volume will be useful as a reading material in graduate level courses dealing with mesoscale systems, weather, climate, monsoon variability and boundary layer. The scientific community at large will find this book a useful addition to their personal and institutional libraries.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 468 pp. Englisch.

Buch. Zustand: Neu. Neuware -It is now accepted that T cell activation by an antigen-presenting cell requires the organization of a supramolecular structure ¿ the immune synapse. This structure, with different types of molecules spatially segregated, is involved in the delivery of quantitative and qualitative signals critical for T cell activation, and therefore in controlling the nature of the immune response. This volume discusses the progress in manipulating components of the immune synapse as a strategy to regulate the immune response in immune pathology, such as transplantation, autoimmunity and allergy. Donnadieu reviews the current knowledge on the molecular composition and organization of the immune synapse and how the formation of this structure can be modulated by chemokines. It is also known that the immune synapse formation is critical for the activation of naive T cells, as well as their functional polarization. The second chapter discusses the conversion of naive T cells into regulatory T cells (Treg) when components of the immune synapse are manipulated in such a way that the T cells receive suboptimal activation signals.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 212 pp. Englisch.

Buch. Zustand: Neu. Neuware -Thepresentbookdealswithvarioustypesoffactorizationproblemsformatrixand operator functions. The problems appear in di erent areasof mathematics and its applications. A uni ed approach to treat them is developed. The main theorems yield explicit necessaryand su cient conditions for the factorizations to exist and explicit formulas for the corresponding factors. Stability of the factors relative to a small perturbation of the original function is also studied in this book. The unifying theory developed in the book is based on a geometric approach which has its origins in di erent elds. A number of initial steps can be found in: (1) the theory of non-selfadjoint operators, where the study of invariant s- spaces of an operator is related to factorization of the characteristic matrix or operator function of the operator involved, (2) mathematical systems theory and electrical network theory, where a cascade decomposition of an input-output system or a network is related to a fact- ization of the associated transfer function, and (3) thefactorizationtheoryofmatrixpolynomialsintermsofinvariantsubspaces of a corresponding linearization. In all three cases a state space representation of the function to be factored is used, and the factors are expressed in state space form too. We call this approach the state space method. It hasa largenumber of applications.For instance, besides the areasreferred to above, Wiener-Hopf factorizations of some classes of symbols can also be treated by the state space method.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 428 pp. Englisch.
