This item is printed on demand - it takes 3-4 days longer - Neuware -Tchebycheff (or Haar) and weak Tchebycheff spaces play a central role when considering problems of best approximation from finite dimensional spaces. The aim of this book is to introduce Haar-like spaces, which are Haar and weak Tchebycheff spaces under special conditions. It studies topics of subclasses of Haar-like spaces, that is, classes of Tchebycheff or weak Tchebycheff spaces, spaces of vector-valued monotone increasing or convex functions and spaces of step functions. The notion of Haar-like spaces provides a general point of view which includes the theories of approximation from the above spaces. The contents are largely new. Graduate students and researchers in approximation theory will be able to read this book with only basic knowledge of analysis, functional analysis and linear algebra. 120 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Inventory changes constitute in all countries a small fraction of the Gross National Product but also a major source or an indicator of cyclical fluctuations. In this volume both possible ways of propagation are investigated by examining in the first part what macroeconomists have learned and still have to learn about inventories in the light of statistical definitions and problems. In the second part, the role of monetary shocks in propagating business cycles is considered through liquidity effects and in relation to inventory adjustment. A possible linkage between inventory and labor market is shown. Finally, new evidence and theoretical insights are provided on the linear-quadratic inventory model and its ability to discriminate econometrically among competing firm behavior. 287 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume is based on the International Conference Logic at Work, held in Amsterdam, The Netherlands, in December 1992. The 14 papers in this volume are selected from 86 submissions and 8 invited contributions and are all devoted to knowledge representation and reasoning under uncertainty, which are core issues of formal artificial intelligence.Nowadays, logic is not any longer mainly associated to mathematical and philosophical problems. The term applied logic has a far wider meaning, as numerous applications of logical methods, particularly in computer science, artificial intelligence, or formal linguistics, testify. As demonstrated also in this volume, a variety of non-standard logics gained increased importance for knowledge representation and reasoning under uncertainty. 252 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The favourable reception of the first edition and the encouragement received from many readers have prompted the author to bring out this new edition. This provides the opportunity for correcting a number of errors, typographical and others, contained in the first edition and making further improvements. This second edition has a new chapter on simplifying Dynamical Systems covering Poincare map, Floquet theory, Centre Manifold Theorems, normal forms of dynamical systems, elimination of passive coordinates and Liapunov-Schmidt reduction theory. It would provide a gradual transition to the study of Bifurcation, Chaos and Catastrophe in Chapter 10. Apart from this, most others - in fact all except the first three and last chapters - have been revised and enlarged to bring in some new materials, elaborate some others, especially those sections which many readers felt were rather too concise in the first edition, by providing more explana tion, examples and applications. Chapter 11 provides some good examples of this. Another example may be found in Chapter 4 where the review of Linear Algebra has been enlarged to incorporate further materials needed in this edition, for example the last section on idempotent matrices and projection would prove very useful to follow Liapunov-Schmidt reduction theory presented in Chapter 9. 336 pp. Englisch.…

Neuware -This volume contains papers from the OOPSLA-93 Conference Workshop on Security for Object-Oriented Systems, held in Washington DC, USA, on 26 September 1993. The workshop addressed the issue of how to introduce an acceptable level of security into object-oriented systems, as the use of such systems becomes increasingly widespread. The topic is approached from two different, but complementary, viewpoints: the incorporation of security into object-oriented systems, and the use of object-oriented design and modelling techniques for designing secure applications. The papers cover a variety of issues, relating to both mandatory and discretionary security, including security facilities of PCTE, information flow control, the design of multilevel secure data models, and secure database interoperation via role translation. The resulting volume provides a comprehensive overview of current work in this important area of research.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 244 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - Print on Demand Titel. Neuware -The Functional Programming Group at the University of Glasgow was started in 1986 by John Hughes and Mary Sheeran. Since then it has grown in size and strength, becoming one of the largest computing science research groups at Glasgow and earning an international reputation. The first Glasgow Functional Programming Workshop was organised in the summer of 1988. Its purpose was threefold: to provide a snapshot of all the research going on within the group, to share research ideas between Glaswegians and colleagues in the U.K. and abroad, and to introduce research students to the art of writing and presenting papers at a semi-formal (but still local and friendly) conference. The success of the first workshop has led to an annual series: Rothesay (1988), Fraserburgh (1989), Ullapool (1990). Portree (1991), Ayr (1992), and the workshop reported in these proceedings: Ayr (1993). Most participants wrote a paper that appeared in the draft proceedings (distributed at the workshop), and each draft paper was presented by one of the authors. The papers were all refereed by several other participants at the workshop, both internal and external, and the programme committee selected papers for these proceedings. Most papers have been revised twice, based firstly on feedback at the workshop, and secondly using the referee reports.Springer-Verlag KG, Sachsenplatz 4-6, 1201 Wien 300 pp. Englisch.…

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -1. 1 Experimental Diabetes in the Sand Rat 1. 1. 1 Zoology Experimental diabetes has been used in numerous animals, of which rodents have been predominant because of their ease of maintenance and handling (Herberg 1979), but some species of ape and monkey have also occasionally been used (Brunk 1971; Malaisse and Malaisse-Lagae 1970). Herberg et al. (1976) divided rodent species into two groups based on the similarity of their metabolic response to the induction of diabetes to the onset of diabetes mellitus in man. In one of these groups (mouse, Mongolian gerbil, Tuco tuca) , the response of the metabolism to the induction of diabetes was similar to the changes seen in the onset of adult-type diabetes mellitus in man; while the other group, which included the sand rat, spiny mouse, Chinese hamster, and Djungarian hamster, responded to diabetes induction in a way suggestive of juvenile insulin-dependent diabetes. Such a subdivision is not without prob lems, however, particularly since difference occur not only between the various species of a group (Herberg et al. 1976), but, in our experience, also between animals of the same species (for instance the sand rat). Hence, the zoology of animals used for experimental purposes must also be taken into account. 1 The sand rat is classified as follows : Species: obesus Genus: Psammomys Subfamily: Gerbillinae Family: Cricetidae Suborder: Myomorpha Order: Rodentia Subclass: Placentalia Class: Mammalia Subphylum: Vertebrata Phylum: Chordata Psammomys obesus was first described by the zoologist P.

In einigen Fallen wird sich dabei leider zeigen, daB sehr 'schlanke' Unternehmen nicht mehr uber die erforderliche Substanz verfugen, um einer dynamischen Marktentwicklung folgen oder gar voranschreiten zu kennen. Fur Unternehmen aller dings, die sich beizeiten darauf vorbereitet haben, ergeben sich groBe Chancen. Konjunkturzyklen sind ein bekanntes Phanomen; jeder seit langerer Zeit Berufstatige hat mehrere solcher Phasen mit gemacht. Damit verbunden ist die Erwartung, daB die Ver haltnisse wieder werden wie in besseren Tagen. Vieles deutet jedoch darauf hin, daB das groBe Revirement zu Beginn der neunziger Jahre einen tiefen Einschnitt in der Industriegeschichte unseres Landes markieren wird. Die erfolgreichen Unternehmen der nahen Zukunft werden sich in einer Welt des Wandels behaupten, komplexe Wertschepfungsprozesse beherrschen, Abschied genommen haben von linearem Denken, ihre Mitarbeiter zu Mitunternehmern gemacht haben, uberlegene Methoden und Instrumente zur Anwendung bringen. Ein Patentrezept fur den Schritt in die Zukunft gibt es nicht. Die Vielfalt der Anforderungen und EinfluBgreBen erfordert individuelle Vorgehensweisen. Deren Konturen werden je doch immer deutlicher. Viele Beispiele aus der Praxis kennen schon heute als Orientierungspunkte dienen. Die Vermittlung von Anforderungen und Rahmenbedingungen, insbesondere aber von Lesungsansatzen und Methoden ist Anliegen dieser Tagung.
