Book Description
With an increasingly challenging commercial environment, and the need imposed by safety principles to reduce both fuel consumption and pollutant emissions, the development of new engines can now benefit from the advances of computational fluid dynamics. Engine CFD is a most challenging simulation problem. This is caused by the spread of time and space scales, the excursion amplitude of most parameters, the high quasi-cyclic unstationarity of engine flows, the importance of minor geometry details, the number of physical and chemical processes including turbulent combustion and multi-phase flows to model. However, engine CFD has now reached a state where it has become a widely used tool, not only for engine understanding, but also increasingly for engine design. Undoubtedly, laser diagnostics in optical access engines have also brought significant help.Contents: 1. State of the art of multi-dimensional modeling of engine reacting flows. 2. Simulation of the intake and compression strokes of a motored 4-valve SI engine with a finite element code. 3. A parallel, unstructured-mesh methodology for device-scale combustion calculations. 4. Large-eddy simulation of in-cylinder flows. 5. Simulation of engine internal flows using digital physics. 6. Automatic block decomposition of parametrically changing volumes. 7. Developments in spray modeling in diesel and direct-injection gasoline engines. 8. Cyto-fluid dynamic theory of atomization processes. 9. Influence of the wall temperature on the mixture preparation in DI gasoline engines. 10. Simulation of cavitating flows in diesel injectors. 11. Recent developments in simulations of internal flows in high pressure swirl injectors. 12. 3D simulation of DI diesel combustion and pollutant formation using a two-component reference fuel. 13. Modeling of NOx and soot formation in diesel combustion. 14. Multi-dimensional modeling of combustion and pollutants formation of new technology light duty diesel engines. 15. 3D modeling of combustion for DI-SI engines. 16. Combustion modeling with the G-equation. 17. Multi-dimensional modeling of the aerodynamic and combustion in diesel engines. 18. CFD aided development of a SI-DI engine. 19. CFD engine applications at FIAT research centre. 20. Application of a detailed emission model for heavy duty diesel engine simulations. 21. CFD based shape optimization of IC engine.

Book Description
This volume contains reviewed papers. The invited lectures considered the many challenges posed by adding one element to the base formed by others: turbulence and turbulent mixing in the absence of combustion through to turbulent mixing dominated by chemistry and combustion. The Symposium benefited from experimental, theoretical and computational contributions, which were focussed on either fundamental or more practical questions. Extensive discussions that followed each paper are included and add to the richness of the Proceedings.

Book Description
The three-volume set LNCS 7510, 7511, and 7512 constitutes the refereed proceedings of the 15th International Conference on Medical Image Computing and Computer-Assisted Intervention, MICCAI 2012, held in Nice, France, in October 2012. Based on rigorous peer reviews, the program committee carefully selected 252 revised papers from 781 submissions for presentation in three volumes. The third volume includes 79 papers organized in topical sections on diffusion imaging: from acquisition to tractography; image acquisition, segmentation and recognition; image registration; neuroimage analysis; analysis of microscopic and optical images; image segmentation; diffusion weighted imaging; computer-aided diagnosis and planning; and microscopic image analysis.

Book Description
The history of urban development is associated with the degradation of rivers - the deterioration of water quality, increased flooding, and the loss of ecological resources. The story of urban streams and rivers is as much a social history as it is a technological one. The control of nature and exploitation of natural resources was at the heart of the industrialisation process and of advances in the co-ordination and effective administration of water-and land-management schemes. Today, new approaches to the management of urban water are a response to advances in scientific knowledge and technology, and of a new concern for quality of life. Environmental improvement and ecological restoration demonstrate confidence in an area, which can enhance economic competitiveness. Along with improvements in air quality, building stock and transport networks, the restoration of stream and river corridors can make a major contribution to the success of urban regeneration schemes. Urban Rivers provides an illustrated overview of the effects of urbanisation on the aquatic environment, potential solutions to the resulting problems, and new opportunities for the regeneration of urban streams and rivers, and of land along their corridors and of adjacent urban areas. The book is written to be accessible to a broad audience and should provide a stimulating and informative introduction to the subject for all those concerned with the urban river environment.

Book Description
This volume reviews recent hydrological and environmental issues resulting from human-induced water pollution practices while providing case studies on the physical, chemical, and eco-biological techniques used to mitigate the impacts of river ecosystem pollution in South Asian countries. The book demonstrates the key methods of measurement, monitoring, mapping, and modeling of river water quality and how it is impacted by pollution and incorporates contemporary geospatial technological applications for the management and sustainability of future water resources. The major topics that the book addresses are the fundamental concepts of river ecosystem health, riverine ecology and habitats, risk assessment of riverine pollution, and technology-based river pollution control strategies. The book will serve as an interdisciplinary guide for researchers, students, and GIS specialists working in various disciplines, including pollution hazards, river ecosystem restoration, water quality, remote sensing, zoology, natural resources management, and environmental geography.
