A Conceptual Framework and a Toolkit for Supporting the Rapid Prototyping of Context-Aware Applications

by Anind K. Dey, Gregory D. Abowd, Daniel Salber , 2001
"... Computing devices and applications are now used beyond the desktop, in diverse environments, and this trend toward ubiquitous computing is accelerating. One challenge that remains in this emerging research field is the ability to enhance the behavior of any application by informing it of the context ..."

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

Dynamic Conditional Correlation: A simple class of multivariate Generalized Autoregressive Conditional Heteroskedasticity Models.

by Robert Engle - Journal of Business & Economic Statistics , 2002
"... Abstract Time varying correlations are often estimated with Multivariate Garch models that are linear in squares and cross products of the data. A new class of multivariate models called dynamic conditional correlation (DCC) models is proposed. These have the flexibility of univariate GARCH models ..."

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.

GOLOG: A Logic Programming Language for Dynamic Domains

by Hector J. Levesque, Raymond Reiter, Yves Lespérance, Fangzhen Lin, Richard B. Scherl , 1994
"... 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. This allo ..."

Rendering Synthetic Objects into Real Scenes: Bridging Traditional and Image-based Graphics with Global Illumination and High Dynamic Range Photography

The people make the place.

by Benjamin Schneider , Benjamin Schneider - Personnel Psychology, , 1987
"... 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 of ..."

Social translucence: An approach to designing systemsthat mesh with social processes.",

by Thomas Erickson , Wendy A Kellogg - Trans. Computer-Human Interaction, , 2002
"... We are interested in designing systems that support communication and collaboration among large groups of people over computer networks. We begin by asking what properties of the physical world support graceful human-human communication in face-to-face situations, and argue that it is possible to d ..."

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

The Determinants of Credit Spread Changes.

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

, 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

Situation Awareness as Distributed Cognition. In

by Henrik Artman, Christer Garbis - Eds.) Cognition and Cooperation. Proceedings of 9th Conference of Cognitive Ergonomics , 1998
"... 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 of ..."

The Situated Function-Behaviour-Structure Framework

by John S. Gero, Udo Kannengiesser - Design Studies , 2002
"... This paper extends the Function-Behaviour-Structure (FBS) framework, which proposed eight fundamental processes involved in designing. This framework did not explicitly account for the dynamic character of the context in which designing takes place, described by the notion of situatedness. This pape ..."
Abstract - Cited by 155 (46 self) - Add to MetaCart
. 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

EDUTELLA: A P2P Networking Infrastructure Based on RDF

by Wolfgang Nejdl, Boris Wolf, Changtao Qu, Stefan Decker, Michael Sintek Ambjörn Naeve, Mikael Nilsson, Matthias Palmer, Tore Risch , 2001
"... Metadata for the World Wide Web is important, but metadata for Peer-to-Peer (P2P) networks is absolutely crucial. In this paper we discuss the open source project Edutella which builds upon metadata standards defined for the WWW and aims to provide an RDFbased metadata infrastructure for P2P applica ..."

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
