"When an application is built, an underlying data model is chosen to make that application effective. Frequently, other applications need the same data, only modeled differently. The solution of copying the underlying data and modeling is costly in terms of storage and makes data maintenance and evolution impossible. View mechanisms are a technique to model data differently for various applicat…
This final report of the Stanford Lisp Performance Study, conducted over a three year period by the author, describes implementation techniques, performance tradeoffs, benchmarking techniques, and performance results for all of the major Lisp dialects in use today. A popular highlevel programming language used predominantly in artificial intelligence, Lisp was the first language to concentrate …
Large transaction-processing applications, such as banking, flight reservations, telecommunications, and networking, demand increasingly high throughput and fast response times. Coupling multiple systems for database transaction processing can provide these systems with higher capacity and availability at a lower cost. Data sharing is one promising architecture for such an environment.This mono…
What is the status of the Free and Open Source Software (F/OSS) revolution? Has the creation of software that can be freely used, modified, and redistributed transformed industry and society, as some predicted, or is this transformation still a work in progress? Perspectives on Free and Open Source Software brings together leading analysts and researchers to address this question, examining spe…
We live in a dynamic economic and commerical world, surrounded by objects of remarkable complexity and power. In many industries, changes in products and technologies have brought with them new kinds of firms and forms of organization. We are discovering news ways of structuring work, of bringing buyers and sellers together, and of creating and using market information. Although our fast-moving…
How recent research in cognitive science offers new ways to understand the interaction of people and computers and develops a new literacy for well-informed, sensitive software design.OCLC-licensed vendor bibliographic record.
Along with text and graphics, images are fast becoming a generic data type for general-purpose computer systems. This poses new problems for the systems designer, who must be able to preprocess digital image data for a wide variety of video and hard copy displays. Digital halftoning, the method by which the illusion of continuous-tone images are created through the arrangement of binary picture…
This volume explores alternative cultural encounters with and around information technologies, encounters that counter dominant, Western-oriented notions of media consumption. The contributors include media practices as forms of cultural resistance and subversion, 'DIY cultures', and other non-mainstream models of technology production and consumption. The contributors - leading thinkers in sci…
Complex communicating computer systems -- computers connected by data networks and in constant communication with their environments -- do not always behave as expected. This book introduces behavioral modeling, a rigorous approach to behavioral specification and verification of concurrent and distributed systems. It is among the very few techniques capable of modeling systems interaction at a …
The Digital Diolectic is an interdisciplinary jam session about our visual and intellectual cultures as the computer recodes technologies, media, and art forms. Unlike purely academic texts on new media, the book includes contributions by scholars, artists, and entrepreneurs, who combine theoretical investigations with hands-on analysis of the possibilities (and limitations) of new technology. …
