The book focuses on the fluid dynamics of cavitation with special reference to high power density turbopumps, where it represents the major source of performance and life degradation. While covering the more fundamental aspects of cavitation and the main kinds of cavitating flows, there is focus on the hydrodynamics and instabilities of cavitating turbopumps. The book also illustrates the alternative approaches for modeling and engineering simulation of cavitating flows.

Traditionally, the study of internal combustion engines operation has focused on the steady-state performance. However, the daily driving schedule of automotive and truck engines is inherently related to unsteady conditions. In fact, only a very small portion of a vehicle's operating pattern is true steady-state, e. g. , when cruising on a motorway. Moreover, the most critical conditions encountered by industrial or marine engines are met during transients too. Unfortunately, the transient operation of turbocharged diesel engines has been associated with slow acceleration rate, hence poor driveability, and overshoot in particulate, gaseous and noise emissions. Despite the relatively large number of published papers, this very important subject has been treated in the past scarcely and only segmentally as regards reference books. Merely two chapters, one in the book Turbocharging the Internal Combustion Engine by N. Watson and M. S. Janota (McMillan Press, 1982) and another one written by D. E. Winterbone in the book The Thermodynamics and Gas Dynamics of Internal Combustion Engines, Vol. II edited by J. H. Horlock and D. E. Winterbone (Clarendon Press, 1986) are dedicated to transient operation. Both books, now out of print, were published a long time ago. Then, it seems reasonable to try to expand on these pioneering works, taking into account the recent technological advances and particularly the global concern about environmental pollution, which has intensified the research on transient (diesel) engine operation, typically through the Transient Cycles certification of new vehicles.

Almost 50 years after the launch of Sputnik, the diversity and criticality of the technology and applications already in place to exploit the high-frontier is impressive. And it is no exaggeration to state that a precondition for meeting human needs, coping with environmental problems, and maintaining security is the successful exploitation of space. Yet no one overview exists to document what we have so far done, and soon plan to accomplish, to utilize the near-Earth space environment. Utilization of Space aims to serve as an authoritative overview for professionals and interested laymen by explaining scientific space utilisation, commercial and entrepreneurial issues, and technological applications. The chapters are written by leading specialists in the respective fields and on a level comprehensible to an educated, but not necessarily technically-trained, reader. Enhanced by informative color illustrations, it is intended not only to transmit useful and timely information to readers, but also to share with them the fascination attached to space activities experienced by those actively engaged in them.

Stefan Baerisch applies a combination of feature modelling and code generation, for which he uses a model-driven approach, in order to facilitate the design of tests by non-programmers. This combination of modelling and code generation allows for a more integrated and more efficient testing process.

There is a growing interest in applying model predictive control techniques to automotive systems, often for different reasons: the simple handling of constraints, the easy use of preview information or the flexibility of the method. Some long-standing problems with this approach, like the high computational burden, have been solved or at least substantially mitigated.

Even so, many issues remain to be elucidated, and, at the same time, papers and results in the increasingly rich literature are not always comparable.

Against this background, the proceedings of the Automotive Model Predictive Control: Models, Methods and Applications workshop investigates whether constrained predictive control is reasonable in automotive control and what is necessary for its application. The workshop, held at the University of Linz on 9th 10th February 2009 brought together workers from academia and industry from three key automotive branches: modeling, control and the application. The workshop included three keynote presentations, each of them contributing to the solution of an essential question.

Which problems in automotive applications need constrained optimal control?

Models of emissions for modern engines for model based control?

Industrial methods and requirements for control schemes?

The results of testing control strategies on a dynamical engine test bench give a feeling for the necessary computing power, the model plant mismatch, etc. and thus for the real application of control laws in production cars."

This important collection of papers from a conference organised by the University of Sussex presents you with twenty-four papers, which Peter Childs and Richard Stobart have collectively drawn together. They present you with distinct areas of automotive design and engineering in order to broaden the perspectives of designers frequently engaged in narrow, specialized activities and therefore, contribute to the advancement of vehicle technology. The papers individually address aspects of: Vehicle dynamics and control; Control and design of the power train; Vehicle safety; Human centered design; Environmental vehicle propulsion; Vehicle design; Experimental techniques; and Control systems technology.

Andreas Riener studies the influence of implicit interaction using vibro-tactile actuators as additional sensory channels for car-driver feedback and pressure sensor arrays for implicit information transmission from the driver toward the vehicle. The results of his experiments suggest the use of both vibro-tactile notifications and pressure sensor images to improve vehicle handling performance and to decrease the driver s cognitive workload.

The general theme of the CE2009 Conference is the recognised requirement for advancements in Concurrent Engineering (CE) with a global perspective for competitive enterprise, economy and ecology. CE appeared in the '80s as the concept of parallel performing engineering design activities and the integration of all related processes. This concept is based on the general assumption that different components of the product life cycle should be considered together and relatively early. The main goal of CE is to make processes more efficient and more resistant to errors.

Since then the whole CE approach has evolved into different forms with different names and has become omnipresent. The industrial presence of CE differs from well established corporation implementations to SME applications. The last twenty years have brought many changes to the organization of product design and manufacturing: engineers have developed narrower specializations; engineers have developed a global presence; engineers work in firms which are final producers or suppliers; sometimes firms create alliances; engineers cooperate and collaborate; and they use different methods and tools to support their engineering activities. As a result the CE approach supports engineers in many ways.

The role of information systems in CE has always been treated as very important. First methodologies and tools were concentrated on offering the possibility to contact people and processes, to make the right information and knowledge available at the right time. The presence of computer tools in CE is treated as standard.

If one looks now at what is going on and at how many different issues are important in design, manufacturing, supply, distribution, etc., one will understand why the context of CE is so rich and so complicated, why there are so many CE specializations and why the main topic of the CE2009 Conference is of great relevance. The plurality of CE specializations mentioned above was reflected in the following CE2009 Conference tracks: Systems Engineering, PLM, Advanced Manufacture, Product Design, Mass Customization, Lean Thinking, Design for Sustainability, Customer Value, Environmental Impact, Knowledge Engineering, SCM, Concurrent System Architecturing, Collaborative Engineering, Web Technologies, Standards, Digital Manufacture, Service Solutions, Purchasing/Procurement, Emotion Engineering. Apart from the above tracks the conference also has seven special sessions in RFID, Collaborative Product Development, Multi-disciplinary Design and Optimization, Design Knowledge Utilization, Competitive Supply Chain Performance, Value Engineering, and Competitive Design.

The proceedings contain 94 papers, demonstrating the multitude of different perspectives contained in this volume. There are papers which are theoretic and conceptual, as well as papers which have very strong industrial roots. There are also very detailed, highly specialized paper, which are closely linked to specific industrial case studies. The reader will also find papers which are based on real processes, but which operate on abstract models and which offer a bridge between industrial reality and academic research.

CE does not develop equally in each area; the direction of development depends on many factors. The content of this volume reflects the variety of issues in today's CE methods and phenomena; consequently, readers will be able to build their own view of the present problems and methods involved in CE.

World War I had an enormous impact on American civilian motor vehicle manufacturers, contributing to the success of some and the failure of others. Beginning with the 1916 Punitive Expedition against Pancho Villa, this history shows how over 200 manufacturers contributed to the war effort, many benefiting strongly from government contracts to produce vehicles for military use. It examines how military mechanization and the automotive industry developed symbiotically, each affecting the other in profound ways. Industrialized warfare didn't necessarily mean efficient production - standardization and mass production techniques were still in their infancy, and some manufacturers were better positioned to take advantage of the crucible of war.

A Clear Outline of Current Methods for Designing and Implementing Automotive Systems

Highlighting requirements, technologies, and business models, the Automotive Embedded Systems Handbook provides a comprehensive overview of existing and future automotive electronic systems. It presents state-of-the-art methodological and technical solutions in the areas of in-vehicle architectures, multipartner development processes, software engineering methods, embedded communications, and safety and dependability assessment.

Divided into four parts, the book begins with an introduction to the design constraints of automotive-embedded systems. It also examines AUTOSAR as the emerging de facto standard and looks at how key technologies, such as sensors and wireless networks, will facilitate the conception of partially and fully autonomous vehicles. The next section focuses on networks and protocols, including CAN, LIN, FlexRay, and TTCAN. The third part explores the design processes of electronic embedded systems, along with new design methodologies, such as the virtual platform. The final section presents validation and verification techniques relating to safety issues.

Providing domain-specific solutions to various technical challenges, this handbook serves as a reliable, complete, and well-documented source of information on automotive embedded systems.

This book constitutes the thoroughly refereed post-proceedings of the First Automotive Software Workshop, ASWD 2004, held in San Diego, CA, USA in January 2004. The 10 revised full papers presented were carefully reviewed and selected from 26 lectures held at the workshop that brought together experts from industry and academia, working on highly complex, distributed, reactive software systems related to the automotive domain.

Energy and environmental security are truly major problems facing our global economy. Fossil fuels, particularly crude oil, are confined to a few regions of the world and the continuity of supply is governed by dynamic political, economic and ecological factors. These factors conspire to force volatile, often high fossil fuel prices while, at the same time, our environmental policies are demanding a reduction in greenhouse gases and toxic emissions. Thus a coherent energy strategy is required, addressing both energy supply and demand, taking account of the whole energy lifecycle including fuel production, transmission and distribution, and energy conversion, and the impact on energy equipment manufacturers and the end-users of energy systems. In the short term, our aim should be to achieve higher energy efficiency and increased energy supply from local energy sources, in particular renewable energy sources. In the long term, a hydrogen-based economy will have an impact on all these sectors. In view of technological developments, vehicle and component manufacturers, transport providers, the energy industry, and even householders are seriously looking at alternative energy sources and fuels and more efficient and cleaner technologies especially hydrogen and hydrogen-powered fuel cells."

With the rise of shared and networked vehicles, autonomous vehicles, and other transportation technologies, technological change is outpacing urban planning and policy. Whether urban planners and policy makers like it or not, these transformations will in turn result in profound changes to streets, land use, and cities. But smarter transportation may not necessarily translate into greater sustainability or equity. There are clear opportunities to shape advances in transportation, and to harness them to reshape cities and improve the socio-economic health of cities and residents. There are opportunities to reduce collisions and improve access to healthcare for those who need it most-particularly high-cost, high-need individuals at the younger and older ends of the age spectrum. There is also potential to connect individuals to jobs and change the way cities organize space and optimize trips. To date, very little discussion has centered around the job and social implications of this technology. Further, policy dialogue on future transport has lagged-particularly in the arenas of sustainability and social justice. Little work has been done on decision-making in this high uncertainty environment-a deficiency that is concerning given that land use and transportation actions have long and lagging timelines. This is one of the first books to explore the impact that emerging transport technology is having on cities and their residents, and how policy is needed to shape the cities that we want to have in the future. The book contains a selection of contributions based on the most advanced empirical research, and case studies for how future transport can be harnessed to improve urban sustainability and justice.

Alternative Fuel Vehicles gives full coverage of all associated qualifications and awards in the emerging field of alternative fuels. It is an essential introduction to the ever-growing demand for vehicles that operate using non-conventional fuels. This first book on AFVs endorsed by the IMI begins with an overview of the subject, ideal for beginners, before outlining what is meant by alternative fuels, why they are necessary, and why climate change and associated legislation are key drivers. Details of how alternative fuels are made, the supply infrastructure, and how these vehicles work are all included. A chapter on fuel cells introduces learners to the use of hydrogen, and one on engines and engine management includes coverage of combustion as an aid to understanding why changing the type of engine fuel is complex. Some basic engine technology is included to help readers new to the subject. Real-life case studies and examples are used to illustrate different technologies in current use, and to speculate on new developments. This book is an ideal companion to any unit of study on alternative fuel, but will also be of interest to working technicians and keen amateurs.

This edited volume presents new insights and challenges in the field of electric mobility in relation to new mobility and infrastructure concepts as well as to renewable energies.

In late 1910, three American adventurers set off on a remarkable around-the-world journey by automobile. Sponsored by the Hupp Motor Car Corporation, the trip was intended to publicize the durability of the Hupmobile and help stimulate export sales. The car was first driven from Detroit to San Francisco-a very difficult journey in its own right in 1910. From San Francisco, the car and its drivers took a steamship to Hawaii, and from there to Fiji, Australia, New Zealand, and Tasmania, unloading and touring at each port of call. The men and their machine spent the next five weeks attempting to drive through the Philippines, and then pushed on to Japan and China, where they managed to stay one step ahead of the Chinese revolution. They then drove across India, and from there, sailed to Egypt, brining the first automobile ever to be seen in that country. Next, the Hupmobilists sailed to Italy. In Rome, the adventurers met Pope Pius X, and then drove north to Germany and France. They crossed the English Channel to Folkstone, toured England, and then ferried from Liverpool to Ireland. They returned to New York in time for the 1912 auto show. In the end, the Hupmobile was driven 41,000 miles and transported by steamship another 28,000. A new world was dawning, both for transportation and for American business enterprise.
