Sommario/riassunto |
|
Le dictionnaire retient que les organisations qui se créent sont le fruit des projets ou des desseins des hommes. Mais cette idée, qui semble frappée d’une certaine évidence, n’a guère suscité de développements dans la sphère académique pour théoriser l’entreprise et plus généralement l’action collective. Si l’on considère qu’il s’agit bien d’un manque, ou si l’on a l’intuition de l’importance du projet collectif pour penser l’action collective, il convient d’en montrer la portée. C’est l’objet de ce livre qui vise à établir que l’action collective naît d’un projet collectif, que ce projet s’exprime par des règles et dans des régulations constitutives de l’acteur collectif lui-même. L’action collective comme communauté de projet se comprend comme communauté de règles vécues, communauté d’apprentissage, avec pour enjeu une capacité d’action commune. Un agir projectif est en jeu aussi bien à l’échelle individuelle que collective, celui-ci doit être pleinement intégré dans l’e ort de théorisation de l’action. |

Sommario/riassunto |
|
This is the revised and extended second edition of the successful basic book on computer arithmetic. It is consistent with the newest recent standard developments in the field. The book shows how the arithmetic and mathematical capability of the digital computer can be enhanced in a quite natural way. The work is motivated by the desire and the need to improve the accuracy of numerical computing and to control the quality of the computed results (validity). The accuracy requirements for the elementary floating-point operations are extended to the |

customary product spaces of computations including interval spaces. The mathematical properties of these models are extracted into an axiomatic approach which leads to a general theory of computer arithmetic. Detailed methods and circuits for the implementation of this advanced computer arithmetic on digital computers are developed in part two of the book. Part three then illustrates by a number of sample applications how this extended computer arithmetic can be used to compute highly accurate and mathematically verified results. The book can be used as a high-level undergraduate textbook but also as reference work for research in computer arithmetic and applied mathematics. |
