Heterogeneous Objects Modelling and Applications : Collection of Papers on Foundations and Practice
Heterogeneous object modelling is a new and quickly developing research area. This book is one of the first attempts to systematically cover the most relevant themes and problems of this new and challenging subject area. It is a collection of invited papers and papers co-authored by the editors. Each chapter presents either new research results or a survey on the following topics:Formal models and abstractions of heterogeneous objects including geometric, topological, discrete and continuous models, operations forming special algebras and conversions between different model types.
Geometrical Geodesy : Using Information and Computer Technology
This book reviews developments in geodesy and hydrography, using a wide variety of electronic and acoustic instruments. The aim is to take stock of the latest fundamental geodetic constants for the 2000s, to focus on dissimilar ellipsoidal areas, distances, and conversion of applications, referenced to an abundant bibliography. It presents a mixture of issues, dealing with reference and time systems, datums, and s-transformations, elucidate multi-dimensional aspects of the information, communication, and computation technology, including the use of parallel computers. Stressing the hands-on methodology, the handbook is of interest to geodetic engineers, consultants, hydrographers, and engineers with an interest in the field of earth sciences.
Environmental Security and Public Safety ; Problems and Needs in Conversion Policy and Research after 15 Years of Conversion in Central and Eastern Europe
Although the end of the Cold War has paved the way to a substantial demilitarisation and conversion, the leftovers of this process – such as former military installations, military training areas, and huge quantities of unserviceable ammunition and equipment – still pose a severe threat to the environment of both NATO and Partner countries.The rehabilitation of these areas for civilian uses is extremely costly and is generally in the short and medium term not possible. For this reason, the development of new methods for the estimation avoidance of risks should receive special priority. In the context of this ARW, the reconnaissance and appraisal of conversion areas with respect to costs, returns, and legal considerations were discussed. The decades-long use of some areas led to the heavy loading of contaminates. Every task of conversion has as its goal the elimination of dangers to humans and nature, and the return of areas to civil use, such that these areas can be used realise economic interests of the society.
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.
Continuous-Time Sigma-Delta A/D Conversion : Fundamentals, Performance Limits and Robust Implementations
This comprehensive book deals with all relevant aspects arising during the analysis, design and simulation of the now widespread continuous-time implementations of sigma-delta modulators. The results of several years of research by the authors in the field of CT sigma-delta modulators are covered, including the analysis and modeling of different CT modulator architectures, CT/DT loop filter synthesis, a detailed error analysis of all components, and possible compensation/correction schemes for the non-ideal behavior in CT sigma-delta modulators. Guidance for obtaining low-power consumption and several practical implementations are also presented. It is shown that all the proposed new theories, architectures and possible correction techniques have been confirmed by measurements on discrete or integrated circuits. Quantitative results are also provided, thus enabling prediction of the resulting accuracy.
Calvinisms First Battleground : Conflict and Reform in the Pays de Vaud, 1528-1559
A specifically Calvinist identity and theology emerged out of two key conflicts in the region: first, the fight to turn away from Catholic practices and traditions a population that had been forced to convert to Protestantism by the Bernese after their conquest of Vaud in 1536; second, the struggle against the Zwinglian political and theological ideas that dominated the Swiss Confederation and differed from the Calvinists' understanding of ecclesiastical discipline, the Eucharist, and predestination. The Pays de Vaud was central to this struggle, for it was subject politically to Zwinglian, German-speaking Bern, but many of its ministers were more strongly influenced by Calvin. Calvin himself was initially excited about the prospects for reform in the region, but frustrations with the Swiss led him and the Genevans increasingly to focus their efforts on France.
Calibration Techniques in Nyquist A/D Converters
It is shown that in order to achieve high speed and high accuracy at high power efficiency, calibration is required. Calibration reduces the overall power consumption by using the available digital processing capability to relax the demands on critical power hungry analog components. Several calibration techniques are analyzed. The calibration techniques presented in this book are applicable to other analog-to-digital systems, such as those applied in integrated receivers. Further refinements will allow using analog components with less accuracy, which will then be compensated by digital signal processing. The presented methods allow implementing this without introducing a speed or power penalty.
Bioenergetics : Energy conservation and conversion
The present book addresses fundamental questions of biological energy transformation and conservation, with a focus on those processes which can now be understood on a structural basis.Current knowledge of selected examples of the biological energy conservation machinery such as cellular oxygen respiration, light-driven energy converters, and fermentation is reviewed. The machinery is highly variable, particularly that within microorganisms, but all of these devices universally rely on one unique underlying physico-chemical principle. The book is a rich source for specialists interested in recent developments in bioenergetics research and novices in the field alike.
