This companion volume to "Alternative Engines for Road Vehicles", discusses the future prospects for conventional and alternative fuels for road vehicle applications. The implications of the energy and emissions from the whole fuel cycle (from production to distribution and final usage) are considered, as are vehicular fuel consumption and exhaust emission characteristics. The book is structured such that each chapter, describing a particular alternative fuel, is self-contained. The reader is able to read about a particular subject that is of interest without having to refer to other chapters to gain a full understanding of the fuel's characteristics, notable developments and demonstration programmes underway worldwide. The final chapter provides an overview and inter-comparison of all the fuels discussed, including point-of-use and life cycle emissions, global warming impacts, fuel storage implications and likely costs. This volume should be of interest to mechanical and petrochemical engineers and anyone with a technical interest in the future developments of motor vehicle fuels.

Divided into two parts. The first part deals with issues relating to the characterization and the rational definition of seismic input and begins with a study of earthquake records that leads to the identification of their damage potential parameters such as the peak ground acceleration and the strong motion duration. Subsequent chapters concern themselves with the deterministic and probabilistic methodologies for producing seismic inputs. Further chapters are dedicated to the generation of artificial seismic input on the basis of stochastic or probabilistic approaches. The second part of this volume deals with ground motion effects on foundation elements and structural integrity. Particular emphasis is given to the interaction of foundation piles with vibrating soils, homogeneous or heterogeneous. The final two chapters are concerned with the possible connection between soil structure interaction (SSI) and structural damage. In both instances records of actual earthquake induce motion are used for such assessments.

Containing the latest in a long line of conferences covering the most recent advances in Boundary Elements and Mesh Reduction Methods (BEM/MRM), this book contains an important chapter in the history of this important method used in science and engineering. The BEM/MRM conference has long been recognised as THE international forum on the technique. The proceedings of the conference therefore constitute a record of the development of the method, running from the initial successful development of boundary integral techniques into the BEM, a method that eliminates the need for an internal mesh, to the recent and most sophisticated Mesh Reduction and even Meshless Methods. Since the boundary elements, mesh reduction, and meshless methods are used in many engineering and scientific fields, the book will be of great interest to all engineers and scientists working within the areas of numerical analysis, boundary elements and meshless methods. Topics covered include: Advanced formulations; Advanced meshless and mesh reduction methods; Structural mechanics applications; Solid mechanics; Heat and mass transfer, Electrical engineering and electromagnetics; Computational methods; Fluid flow modelling; Damage mechanics and fracture; Dynamics and Vibrations Engineering applications.

Biomass is a continuously renewed source of energy formed from or by a wide variety of living organisms. Through biochemical and thermochemical processes, it is converted into gaseous, liquid or solid biofuels, which already meet a significant share of the current world energy needs. Because of their contribution to the sustainability of energy supply, reduction of green house gas emissions as well as local employment and energy self-reliance, research interest and activity in enhancing biofuel energy output, efficiency and performance remain strong. The first part of this volume comprises five articles mainly concerned with biomass resource potential and management. More specifically, the reported investigations assess grass and lawn substrates, rapeseed straw and microalgae from Upflow Anaerobic Sludge Blanket (UASB) reactor effluents as possible sources of biogas, bioethanol and biodiesel, respectively. The emphasis in the subsequent group of eleven articles is on biomass conversion processes, aiming at assessing performance as well as output quality and diversity. Biodiesel, a fluid biofuel produced from biomass with high lipids such as rapeseed oil, sunflowers and soy beans, is the focus of two articles: the first investigates the effect of biodiesel blending with diesel fuel on diesel engine performance and emissions, the second assesses the efficiency of catalytic reforming of biodiesel into a gaseous mixture, used directly as Solid Oxide Fuel Cell (SOFC) fuel. In the last three articles, the prospects of biofuels as viable sources of energy are examined within European contexts. This volume addresses a significant number of important themes and thus combines subject breadth and density with in-depth study of biomass resourcing and processing as well as the issue of biofuel and renewable energy sustainability.

A marine engineer needs to have a broad background of knowledge within several aspects of marine design and operations. These aspects relate to the design and evaluation of offshore facilities. Such needs arise in the marine industries, in the offshore oil and gas industry as well as in the offshore renewable industry. Developed by a practicing engineer with four decades of experience dealing with engineering problems, Marine Technology and Operations: Theory &amp; Practice takes a practical and solid mathematical approach to marine engineering. The book covers areas of knowledge that the author has found from experience to be essential to marine engineers. It may also serve as a teaser for those who will go into more depth on the different thematic aspects discussed in the book. The book includes qualitative risk analysis which is considered an excellent tool to identify risks in marine operations. The book can serve as a handbook for PhD students and researchers who need a handy introduction to solving marine-technology related problems. It could also serve as an introductory textbook for master degree courses in marine sciences, as well as an inspiration for teachers who will extend the material into specialization courses on stability of vessels, higher order wave analysis, nonlinear motions of vessels, arctic offshore engineering, etc.

Recently a renewed emphasis on the benefits of proper use of natural light has focused attention on the need to define a new paradigm, to properly assess the variability of the amount light that can be used not only to enhance the presence of natural light as an instrument to outline indoor space expressively, but also to reduce the demand for electricity and thermal energy consumption in buildings. "Assessment of Daylight Performance in Buildings" deals with the many advantages associated with the use of natural light, comparing architectural experiences, technological devices and calculation methods. It explores the spatial qualities of built environments through the use of natural light, involving energy-saving strategies and visual comfort definition, although in current architectural practice, daylight is a greatly underexploited natural resource. A proper natural lighting system, tailored to the requirements of architectural form and customized to occupants functional desires is an essential support to modern climate control policies, as well as to energy-saving measures and to reducing thermal loads. An in-depth investigation of the different methods of assessment natural light reveals deficiencies and inaccuracies, showing the need to define a new calculation procedure that merges purely qualitative assessment with the new dynamic approach, involving users' preferences. Primarily intended for architects and designers, this book provides an introduction to the types of problems encountered and current available solutions to enhance and to convey the right dose of daylight inside the buildings, with a close attention to energy-saving strategies and to indoor visual comfort. Written for practitioners whose work is related to design and retrofit actions, the book will also be of interest to postgraduate students and lecturers dealing with indoor design optimization and energy-saving issues.
