it of the context of its use. By context, we refer to any information that characterizes a situation related to the interaction between humans, applications and the surrounding environment. Context-aware applications promise richer and easier interaction, but the current state of research in this field is still far

coupled with parsimonious parametric models for the correlations. They are not linear but can often be estimated very simply with univariate or two step methods based on the likelihood function. It is shown that they perform well in a variety of situations and provide sensible empirical results.

This paper proposes a new logic programming language called GOLOG whose interpreter automatically maintains an explicit representation of the dynamic world being modeled, on the basis of user supplied axioms about the preconditions and effects of actions and the initial state of the world

We present a method that uses measured scene radiance and global illumination in order to add new objects to light-based models with correct lighting. The methodusesahighdynamicrangeimagebasedmodelofthescene, ratherthansyntheticlightsources,toilluminatethe new objects. Tocomputetheillumination

A framework for understanding the etiology of organizational behavior is presented. The framework is ]based on theory and research from interactional psychology, vocational psychology, I/O psychology, and organizational theory. The framework proposes that organizations are functions of the kinds

upon their social experience and expertise to structure their interactions with one another. To motivate and focus our ideas we develop a vision of knowledge communities, conversationally based systems that support the creation, management and reuse of knowledge in a social context. We describe our

, Stanton, and Whitelaw (1997), who find that a 3-factor model explains over 90 percent of Ginnie Mae yields, but that the remaining variation apparently cannot be explained by the changes in the yield curve. 2 In contrast, our multiple-factor model explains only about one-quarter of the variation in credit

In this paper we argue that the predominant models of Situation Awareness (SA) are inadequate for the study of systems operated by teams. The reason for this is that these models are based on mentalistic assumptions focusing almost exclusively on individuals. We suggest that, to study the control

. This paper describes this concept as a recursive interrelationship between different environments, which, together with a model of constructive memory, provides the foundation of a situated FBS framework. The eight fundamental processes are then reconstructed within this new framework to represent designing

applications, building on the recently announced JXTA Framework. We describe the goals and main services this infrastructure will provide and the architecture to connect Edutella Peers based on exchange of RDF metadata. As the query service is one of the core services of Edutella, upon which other services
