Buch. Zustand: Neu. Neuware - Those charged with protection of resources falling within the public domain, including submerged sites, continuously strive to find the best management solutions. Given the advent of recreational diving in the last half century and advances in underwater survey and exploration technology, pressures have increased dramatically on submerged archaeological sites. Users of these p- lic resources fall into groups with various needs and agendas, including divers, fishermen, salvers, scientists, and the tourism industry (Kauru and Hoagland, 1994). To insure that all people are represented in the decision-making process, site managers have increasingly argued that public outreach and education is vitally important. 'Without public appreciation of the importance of archa- logical sites and information,' states one early proponent, 'there can be no effective protection of sites. ' Archaeologist Charles McGimsey (1972:6) c- tinues, '. . . the greater one's knowledge of archaeology, regardless of formal training in the subject, the greater the responsibility to take the initiative to lead, to teach, and to persuade others to do likewise. ' Some also suggest that rather than rely solely on museum interpretive displays the public should be allowed to observe heritage resources in their original setting, which can strengthen the spirituality and meaningfulness of the experience (Carter and Horneman, 2001:67-68). Managers must be aware that from a purely archaeological perspective, public access is not a preferred option for those sites that still retain significant, undo- mented remains.

Buch. Zustand: Neu. Neuware - Advances for In-Vehicle and Mobile Systems: Challenges for International Standards is organized to bring together the most active scholars working on the latest techniques, standards, and emerging deployment on 'living in the age of wireless communications and smart vehicular systems.' The objective is to incorporate speech, dialog, video, image, vehicular sensory data, and wireless communication modalities to model the total behavior of the driver and use that model towards personalization of the vehicle to provide a more comfortable and safer driving experience. The format of this work centers on four themes: driver and driving environment recognition, telecommunication applications, noise reduction, and dialog in vehicles.Advances for In-Vehicle and Mobile Systems: Challenges for International Standards, is appropriate for researchers, engineers, and professionals working in signal processing technologies, next generation vehicle design, and networks for mobile platforms.

Buch. Zustand: Neu. Neuware - Marianne Horinko Executive Vice President, Global Environment and Technology Foundation On August 7, 1978, President Carter declared a state of emergency in the community of Love Canal, New York. The President urged residents of Love Canal to evacuate, not because of a recent catastrophic event, but because of something that occurred in the 1940's and 1950's. This Niagara Falls community had been developed on land that was formerly used as a landfill. Although the landfill was closed in 1953, it had been a dumping ground for tons of chemical wastes, and that waste would eventually create an environment extremely dangerous to human health. The image of chemicals seeping into the basements of American homes would produce widespread panic, but would also raise the environmental consciousness of a nation, and produce a legislative response that was equal to the task. Americans celebrated the first Earth Day in April, 1970. Throughout the rest of the decade, we passed legislation intended to fulfill the promise of that day: to create a clean and safe environment. However, there were still holes in our environmental protection in 1978, evidenced by the problems at Love Canal. In response, Congress passed the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) or, as many people call it, Superfund. Passed in 1980, this law was intended to address problems like the ones faced at Love Canal.

Buch. Zustand: Neu. Neuware - Introduction to Contact Mechanics, Second Edition is a gentle introduction to the mechanics of solid bodies in contact for graduate students, post doctoral individuals, and the beginning researcher.This second edition maintains the introductory character of the first with a focus on materials science as distinct from straight solid mechanics theory. Every chapter has been updated to make the book easier to read and more informative. A new chapter on depth sensing indentation has been added, and the contents of the other chapters have been completely overhauled with added figures, formulae and explanations.The author begins with an introduction to the mechanical properties of materials, general fracture mechanics and the fracture of brittle solids. This is followed by a detailed description of indentation stress fields for both elastic and elastic-plastic contact. The discussion then turns to the formation of Hertzian cone cracks in brittle materials, subsurface damage in ductile materials, and the meaning of hardness. The author concludes with an overview of practical methods of indentation.

Buch. Zustand: Neu. Neuware - With dramatic increases in on-chip packing densities, routing congestion has become a major problem in integrated circuit design, impacting convergence, performance, and yield, and complicating the synthesis of critical interc- nects. The problem is especially acute as interconnects are becoming the performance bottleneck in modern integrated circuits. Even with more than 30% of white space, some of the design blocks in modern microprocessor and ASIC designs cannot be routed successfully. Moreover, this problem is likely to worsen considerably in the coming years due to design size and technology scaling. There is an inherent tradeo between choosing a minimum delay path for interconnect nets, and the need to detour the routes to avoid 'tra c jams'; congestion management involves intelligent allocation of the available int- connect resources, up-front planning of the wire routes for even distributions, and transformations that make the physical synthesis ow congestion-aware. The book explores this tradeo that lies at the heart of all congestion m- agement, in seeking to address the key question: how does one optimize the traditional design goals such as the delay or the area of a circuit, while still ensuring that the circuit remains routable It begins by motivating the c- gestion problem, explaining why this problem is important and how it will trend. It then progresses with comprehensive discussions of the techniques available for estimating and optimizing congestion at various stages in the design ow.

Buch. Zustand: Neu. Neuware - Although some examples of phase portraits of quadratic systems can already be found in the work of Poincaré, the first paper dealing exclusively with these systems was published by Büchel in 1904. By the end of the 20th century an increasing flow of publications resulted in nearly a thousand papers on the subject.This book attempts to give a presentation of the advance of our knowledge of phase portraits of quadratic systems, paying special attention to the historical development of the subject. The book organizes the portraits into classes, using the notions of finite and infinite multiplicity and finite and infinite index. Classifications of phase portraits for various classes are given using the well-known methods of phase plane analysis.
