Flux-corrected transport : Principles, algorithms, and applications
Addressing students and researchers as well as CFD practitioners, this book describes the state of the art in the development of high-resolution schemes based on the Flux-Corrected Transport (FCT) paradigm. Intended for readers who have a solid background in Computational Fluid Dynamics, the book begins with historical notes by J.P. Boris and D.L. Book. Review articles that follow describe recent advances in the design of FCT algorithms as well as various algorithmic aspects. The topics addressed in the book and its main highlights include: the derivation and analysis of classical FCT schemes with special emphasis on the underlying physical and mathematical constraints; flux limiting for hyperbolic systems; generalization of FCT to implicit time-stepping and finite element discretizations on unstructured meshes and its role as a subgrid scale model for Monotonically Integrated Large Eddy Simulation (MILES) of turbulent flows. The proposed enhancements of the FCT methodology also comprise the prelimiting and 'failsafe' adjustment of antidiffusive fluxes, the use of characteristic variables, and iterative flux correction. The cause and cure of detrimental clipping/terracing effects are discussed. Many numerical examples are presented for academic test problems and large-scale applications alike.

Fluid Transport in Nanoporous Materials : Proceedings of the NATO Advanced Study Institute, held in La Colle sur Loup, France, 16-28 June 2003
The most promising include molecular sieves which are being developed as inorganic or polymeric systems with 0. 3-30nm in pore dimensions. These nanoporous solids have a broad spectrum of applications in chemical and biochemical processes. The unique applications of molecular sieves are based on their sorption and transport selectivity. Yet, the transport processes in nanoporous systems are not understood well. At the same time, the theoretical capabilities have increased exponentially catalyzed by increases in computational capabilities. The interactions between a diffusing species and the host solid are being studied with increasing details and realism. Further, in situ experimental techniques have been developed which give an understanding of the interactions between diffusing species and nanoporous solids that was not available even a few years ago. The time was ripe to bring together these areas of common interest and study to understand what is known and what has yet to be determined concerning transport in nanoporous solids. Molecular sieves are playing an increasing role in a broad range of industrial petrochemical and biological processes. These include shape-selective separations and catalysis as well as sensors and drug delivery. Molecular sieves are made from inorganic as well as organic solids, e. g. , polymers. They can be employed in packed beds, as membranes and as barrier materials. Initially, the applications of molecular sieves were dominated by the use of zeolites.
Fields and Galois Theory
The pioneering work of Abel and Galois in the early nineteenth century demonstrated that the long-standing quest for a solution of quintic equations by radicals was fruitless: no formula can be found. The techniques they used were, in the end, more important than the resolution of a somewhat esoteric problem, for they were the genesis of modern abstract algebra. This book provides a gentle introduction to Galois theory suitable for third- and fourth-year undergraduates and beginning graduates. The approach is unashamedly unhistorical: it uses the language and techniques of abstract algebra to express complex arguments in contemporary terms. Thus the insolubility of the quintic by radicals is linked to the fact that the alternating group of degree 5 is simple - which is assuredly not the way Galois would have expressed the connection.
Field Emission in Vacuum Microelectronics
Field emission is a phenomenon described by quantum mechanics. Its emission capability is millions times higher than that of any other known types of electron emission. Nowadays this phenomenon is experiencing a new life due to wonderful applications in the atomic resolution microscopy, in electronic holography, and in the vacuum micro- and nanoelectronics in general. The main field emission properties, and some most remarkable experimental facts and applications, are described in this book.
Ferro- and Antiferroelectricity : Order/Disorder versus Displacive
Solid-state systems are frequently classi?ed according to their physical, str- tural or chemical properties. Such schemes are extremely helpful since pr- erties related to any such classi?cation are typically known and facilitate id- tifying solids with special material classes. The best-known examples of these schemes are conductivity or resistivity measurements by means of which m- als are easily distinguishable from insulators. However, frequently clear-cut decisions between material classes are not possible, since anisotropy, chemical composition, binding forces and local effects wash out distinct properties and lead to competition or coexistence. Such unresolved situations are especially typical for transition metal oxides that exhibit a variety of ground-state properties in a fascinating way.
Exponentially Dichotomous Operators and Applications
In this monograph the natural evolution operators of autonomous first-order differential equations with exponential dichotomy on an arbitrary Banach space are studied in detail. Characterizations of these so-called exponentially dichotomous operators in terms of their resolvents and additive and multiplicative perturbation results are given. The general theory of the first three chapters is then followed by applications to Wiener-Hopf factorization and Riccati equations, transport equations, diffusion equations of indefinite Sturm-Liouville type, noncausal infinite-dimensional linear continuous-time systems, and functional differential equations of mixed type.
European Variations as a Key to Cooperation
This book offers a novel view on the benefits of a lasting variation between the member states in the EU. In order to bring together thirty very different European states and their citizens, the EU will have to offer more scope for variation. Unlike the existing differentiation by means of opt-outs and deviations, variation is not a concession intended to resolve impasses in negotiations; it is, rather, a different structuring principle. It takes differences in needs and in democratically supported convictions seriously
Essential Software Architecture
Job titles like "Technical Architect" and "Chief Architect" nowadays abound in the software industry, yet many people suspect that "architecture" is one of the most overused and least understood terms in professional software development. Gorton's book helps resolve this predicament. It concisely describes the essential elements of knowledge and key skills required to be a software architect. The explanations encompass the essentials of architecture thinking, practices, and supporting technologies.
Esercizi di finanza matematica = Mathematical finance exercises
This is a collection of exercises that illustrates some fundamental aspects of Mathematical Finance, in particular the valuation of derivatives. It is aimed at students of master's degree courses, but can also be successfully used in first level degree courses, by students who have adequate mathematical training (degree courses in mathematics, engineering). The resolution of the exercises is addressed with the use of methods of both Probability Theory (stochastic processes) and Mathematical Analysis (Partial Derivative Equations).

Enabling Sustainable Energy Transitions : Practices of legitimation and accountable governance
This book reframes sustainable energy transitions as being a matter of resolving accountability crises. It demonstrates how the empirical study of several practices of legitimation can analytically deconstruct energy transitions, and presents a typology of these practices to help determine whether energy transitions contribute to sustainability.
Economic Geology of Natural Gas Hydrate
This is the first book that attempts to broadly integrate the most recent knowledge in the fields of hydrate nucleation and growth in permafrost regions and marine sediments. Gas hydrate reactant supply, growth models, and implications for pore fill by natural gas hydrate are discussed for both seawater precursors in marine sediments and for permafrost hydrate. These models for forming hydrate concentrations that will constitute targets for exploration are discussed, along with exploration methods. Thermodynamic models for the controlled conversion of hydrate to natural gas, which can be recovered using conventional industry practices, suggest that a number of different types of hydrate occurrence are likely to be practical sources of hydrate natural gas. Current progress in the various aspects of commercial development of hydrate gas deposits are discussed, along with the principal extractive issues that have yet to be resolved.

Satellite remote sensing for Earth science data has been rapidly expanding during the last decade. Volume 1 of this two volume monograph covers missions/sensors, such as Sea-viewing Wide Field-of-view Sensor (SeaWiFS), Tropical Rainfall Measuring Mission (TRMM), Total Ozone Mapping Spectrometer (TOMS), Atmospheric Infrared Sounder (AIRS), and Advanced Microwave Sounding Unit (AMSU). It also discusses the NPOESS and NPP missions. Emphasis was placed on the recently launched Moderate Resolution Imaging Spectroradiometer (MODIS) on board of both Terra and Aqua. Some key MODIS science team members were invited to contribute several chapters. The core of this monograph arose from the workshop for Earth Science Satellite Remote Sensing held at George Mason University (GMU) in October 2002. Both volumes are designed to give scientists and graduate students with limited remote sensing background a thorough introduction to current and future NASA, NOAA and other Earth science remote sensing missions.
Earth Observation of Global Change : The Role of Satellite Remote Sensing in Monitoring the Global Environment
Global Change is increasingly considered a critical topic in environmental research. Remote sensing methods provide a relevant tool to monitor global variables, since they offer a systematic coverage of the Earth Surface, at different spatial, spectral and temporal resolutions. The data provided by Earth Observation Satellites are being operationally used for monitoring atmospheric conditions, ice sheets and glaciar movements, crop dynamism and land use changes, deforestation and desertification processes, as well as water conditions. The book includes an analysis of the leading missions in global Earth observation, and then reviews the main fields in which remote sensing methods are providing vital data for global change studies.
