Join the family Trotter with their get-rich-quick scheming and back-of-a-lorry sales pitch. This collection covers the first five series of the hilarious BBC sitcom and contains specially-written, original material, including the Trotter Dictionary, Rodney's CV and the Trotter Guide to Seduction.

Das Problem des Gleitlagers zeichnet sich durch eine ausserordent- liche Vielfaltigkeit aus. Von der Hydrodynamik der Schmierung als der theoretischen Grundlage der Lagerreibung fuhrt es uber die Werkstoff- kunde, uber die Physik und Chemie der Oberflachen fester Koerper bei Fehlen und Vorhandensein von Schmiermitteln, uber Konstitutions- fragen dieser Schmiermittel bis zur Lagergestaltung, Lagerfertigung und Prufung und Bewahrung der Lager in Laboratorium und Betrieb. Diese Sachlage bringt es mit sich, dass ubersichtliche Bearbeitungen zumeist nur ein Teilgebiet des gesamten Fragenkomplexes betreffen. Neben mehreren Darstellungen der hydrodynamischen Theorie der Lagerrei- bung gibt es umfassende uberblicke uber das Gebiet der Gleitlagerwerk- stoffe und eingehende Behandlungen der Schmiermittelfragen. uber das neuerdings als so wesentlich erkannte Gebiet der Wechselwirkung von Gleitwerkstoff und Schmiermittel ist kurzlich das Werk "The friction and lubrication of solids" von T. P. BOWDEN und P. TABOR erschienen. Im deutschen Schrifttum, das zahlreiche interessante Originalarbeiten aufweist, fehlt hieruber ein entsprechender, den augenblicklichen Stand kennzeichnender uber blick. Alle diese Umstande liessen es uns reizvoll erscheinen, den Versuch zu unternehmen, eine umfassende Darstellung des gesamten Fragen- komplexes ohne besondere Betonung des einen oder anderen Teilgebietes zu versuchen als Unterlage fur die Beschaftigung mit dem Gebiet des Gleitlagers, welcher Art immer sie sei. Mitveranlassung fur die Verwirk- lichung unseres Vorhabens war weiterhin eine Anregung seitens des Herrn Dr. K. RIEDERER, Stuttgart. Wesentlich zuruckgreifen konnten wir bei der Darstellung auf lange gemeinsam bei der Metallgesellschaft A. G., Frankfurt/Main verbrachte Arbeitsjahre.

Entrepreneurship education at tertiary institutions ranks high on policy agendas in Europe and the US. The increase in resources allocated to this kind of education comes along with a growing demand for justifying these investments. A better understanding of the size and nature of entrepreneurship education effects is critical. Richard Weber addresses this question and analyzes the effects of a large-scale compulsory entrepreneurship course on students' entrepreneurial intentions by employing a quasi-experimental approach. Moreover, he highlights the role of social interactions among students in building entrepreneurial skills. The results yield important implications for public policy, sponsors and lecturers of entrepreneurship education.?

In 1989 the first edition of this book set out Gittins' pioneering index solution to the multi-armed bandit problem and his subsequent investigation of a wide of sequential resource allocation and stochastic scheduling problems. Since then there has been a remarkable flowering of new insights, generalizations and applications, to which Glazebrook and Weber have made major contributions. This second edition brings the story up to date. There are new chapters on the achievable region approach to stochastic optimization problems, the construction of performance bounds for suboptimal policies, Whittle's restless bandits, and the use of Lagrangian relaxation in the construction and evaluation of index policies. Some of the many varied proofs of the index theorem are discussed along with the insights that they provide. Many contemporary applications are surveyed, and over 150 new references are included. Over the past 40 years the Gittins index has helped theoreticians and practitioners to address a huge variety of problems within chemometrics, economics, engineering, numerical analysis, operational research, probability, statistics and website design. This new edition will be an important resource for others wishing to use this approach.

Recent advances in technology, combined with the deregulation of the telecommunication market and the proliferation of the Internet, have created a highly competitive environment for communication service providers. There is no simple recipe for pricing network service contracts in all contexts. Pricing is a complex subject, which depends on parameters of the actual market - including the degree of competition and customer demand - and parameters of technology, such as resource consumption, network architecture, resource availability, and cost. Pricing Communication Networks: Economics, Technology and Modelling covers many important issues in providing new services, the relation between pricing and resource allocation in networks, and the emergence of the Internet and its pricing. It provides a framework of mathematical models for pricing multidimensional contracts with quality of service guarantees, and includes a useful background on network services and contracts, network technology, basic economics, and pricing strategy. *Provides a broad overview of network services and contracts. *Includes a primer on modern network technology and the economic concepts relevant to pricing and competition. *Discusses mathematical models for multiplexing bursty traffic flows, and applies these to measuring network capability and deriving pricing strategies for services with statistical quality guarantees. *Discusses definitions of cost for communication networks and explains the intricacies of cost-based pricing. *Explains congestion pricing and its potential applications in the Internet. *Illustrated throughout by detailed examples and figures. *Includes coverage of specialist topics, such as regulation, multicasting, interconnection, and auctions. Pricing Communication Networks: Economics, Technology and Modelling is an essential reference for graduate students, researchers and practitioners from electrical engineering, computer science, economics and operations research. It can be used by economists to fill in the gaps in their knowledge of network services and technology and by engineers and operational researchers to gain the background in the economics that is required to understand how to price communication networks effectively.
