Marcellliesz's lectures delivered on October 1957 -January 1958 at the Uni versity of Maryland, College Park, have been previously published only infor mally as a manuscript entitled CLIFFORD NUMBERS AND SPINORS (Chap ters I - IV). As the title says, the lecture notes consist of four Chapters I, II, III and IV. However, in the preface of the lecture notes lliesz refers to Chapters V and VI which he could not finish. Chapter VI is mentioned on pages 1, 3, 16, 38 and 156, which makes it plausible that lliesz was well aware of what he was going to include in the final missing chapters. The...

"Great progress has been made in electrical science, chiefly in Germany, by cultivators of the theory of action at a distance. The valuable electrical measurements of W. Weber are interpreted by him according to this theory, and the electromagnetic speculation which was originated by Gauss, and carried on by Weber, Riemann, F. and C. Neumann, Lorenz, etc., is founded on the theory of action at a distance, but depending either directly on the relative velocity of the particles, or on the gradual propagation of something, whether potential or force, from the one particle to the other. The great...

In recent years, analysts, researchers and environmental policy makers have been faced with a serious shortage of empirical data on environmental phenomena. In fact, the information gathered by various organisations has not yet been systematically classified into a consistent system of accounts.
This book presents the results of a joint research effort by the Fondazione Eni Enrico Mattei and Italy's Central Statistical Office (ISTAT) to design a system of accounts for natural and environmental resources. The resulting environmental accounts can be integrated with the existing system of...

Mining Very Large Databases with Parallel Processing addresses the problem of large-scale data mining. It is an interdisciplinary text, describing advances in the integration of three computer science areas, namely intelligent' (machine learning-based) data mining techniques, relational databases and parallel processing. The basic idea is to use concepts and techniques of the latter two areas - particularly parallel processing - to speed up and scale up data mining algorithms.
The book is divided into three parts. The first part presents a comprehensive review of intelligent...

The American public has a fascination with railroad wrecks that goes back a long way. One hundred years ago, staged railroad accidents were popular events. At the Iowa State fair in 1896, 89,000 people paid $20 each, at current prices, to see two trains, throttles wide open, collide with each other. "Head-on Joe" Connolly made a business out of "cornfield meets" holding seventy-three events in thirty-six years. Picture books of train wrecks do good business presumably because a train wreck can guarantee a spectacular destruction of property without the messy loss of life associated with...

Economics of Urban Highway Congestion and Pricing offers the most extensive examination to date of the relationship between congestion tolls and highway capacity in the long run. This study breaks new ground in the economic theory of optimal road capacity by including theoretical contributions, empirical studies, and simulation experiments that all pertain to the general topic reflected in the title. The book is organized into four sections: 1) highway traffic flow; 2) commuter choice of tollways versus freeways; 3) congestion pricing in the short run; and 4) road capacity and...

Symbolic Analysis in Analog Integrated Circuit Design provides an introduction to computer-aided circuit analysis and presents systematic methods for solving linear (i.e. small-signal) and nonlinear circuit problems, which are illustrated by concrete examples. Computer-aided symbolic circuit analysis is useful in analog integrated circuit design. Analytic expressions for the network transfer functions contain information that is not provided by a numerical simulation result. However, these expressions are generally extremely long and difficult to interpret; therefore, it is necessary...

The 17 chapters in this book, which evolved from a conference on measuring the contributions of ITS sponsored by the California Department of Transportation in February 2002, examine the costs and benefits of ITS in an economic and business policy context.
Section 1 examines the broad theme of how and what ITS contributes to the economy and how one makes a business case for ITS. Section 2 includes three chapters on ITS applications in mass transit. Section 3 explores ITS applications in the automobile/highway system. Section 4 considers integrative issues including how ITS is perceived...

To honour the remarkable contribution of Michel David in the inception, establishment and development of Geostatistics, and to promote the essence of his work, an international Forum entitled Geostatistics for the Next Century was convened in Montreal in June 1993. In order to enhance communication and stimulate geostatistical innovation, research and development, the Forum brought together world leading researchers and practitioners from five continents, who discussed-debated current problems, new technologies and futuristic ideas. This volume contains selected peer-reviewed papers from the...

Economics of the U.S. Commercial Airline Industry: Productivity, Technology and Deregulation illustrates the impact of upstream technological change in capital goods (aircraft and aircraft engines) on demand, productivity, and cost reduction in the U.S. airline industry for the years 1970-1992. The aim is to separate supply-side technology push from demand pull in determining investment in aircraft in the US airline industry. The focus of inquiry in this study is at the company level, so the measures are sensitive to company differences such as financial costs, payload, and...
