Goal-directed Requirements Acquisition

by Anne Dardenne , Axel van Lamsweerde, Stephen Fickas - SCIENCE OF COMPUTER PROGRAMMING , 1993
"... Requirements analysis includes a preliminary acquisition step where a global model for the specification of the system and its environment is elaborated. This model, called requirements model, involves concepts that are currently not supported by existing formal specification languages, such as goal ..."

Real-Time 3D Model Acquisition

by Szymon Rusinkiewicz, Olaf Hall-Holt, Marc Levoy , 2002
"... The digitization of the 3D shape of real objects is a rapidly expanding field, with applications in entertainment, design, and archaeology. We propose a new 3D model acquisition system that permits the user to rotate an object by hand and see a continuously-updated model as the object is scanned. Th ..."

Model-Driven Data Acquisition in Sensor Networks

by Amol Deshpande , Carlos Guestrin, Samuel R. Madden, et al. - IN VLDB , 2004
"... Declarative queries are proving to be an attractive paradigm for interacting with networks of wireless sensors. The metaphor that "the sensornet is a database" is problematic, however, because sensors do not exhaustively represent the data in the real world. In order to map the raw sensor ..."

approximations with probabilistic confidences, significantly more efficient to compute in both time and energy. Utilizing the combination of a model and live data acquisition raises the challenging optimization problem of selecting the best sensor readings to acquire, balancing the increase in the confidence

Efficient Variants of the ICP Algorithm

by Szymon Rusinkiewicz, Marc Levoy - INTERNATIONAL CONFERENCE ON 3-D DIGITAL IMAGING AND MODELING , 2001
"... The ICP (Iterative Closest Point) algorithm is widely used for geometric alignment of three-dimensional models when an initial estimate of the relative pose is known. Many variants of ICP have been proposed, affecting all phases of the algorithm from the selection and matching of points to the minim ..."

Cognitive load during problem solving: effects on learning

by John Sweller - COGNITIVE SCIENCE , 1988
"... Considerable evidence indicates that domain specific knowledge in the form of schemes is the primary factor distinguishing experts from novices in problem-solving skill. Evidence that conventional problem-solving activity is not effective in schema acquisition is also accumulating. It is suggested t ..."

capacity which is consequently unavailable for schema acquisition. A computational model and experimental evidence provide support for this contention. Theoretical and practical implications are discussed.

3D Model Acquisition from Extended Image Sequences

by Paul Beardsley, Phil Torr, Andrew Zisserman , 1995
"... This paper describes the extraction of 3D geometrical data from image sequences, for the purpose of creating 3D models of objects in the world. The approach is uncalibrated - camera internal parameters and camera motion are not known or required. Processing an image sequence is underpinned by token ..."

The effect of national culture on the choice of entry mode

by Bruce Kogut, Harbir Singh - Journal of International Business Studies , 1988
"... Abstract. Characteristics of national cultures have frequently been claimed to influence the selection of entry modes. This article investigates this claim by developing a theoretical argument for why culture should influence the choice of entry. Two hypotheses are derived which relate culture to en ..."

to entry mode choice, one focussing on the cultural distance between countries, the other on attitudes towards uncertainty avoidance. Using a multinomial logit model and controlling for other effects, the hypotheses are tested by analyzing data on 228 entries into the United States market by acquisition

On Language and Connectionism: Analysis of a Parallel Distributed Processing Model of Language Acquisition

by Steven Pinker, Alan Prince - COGNITION , 1988
"... Does knowledge of language consist of mentally-represented rules? Rumelhart and McClelland have described a connectionist (parallel distributed processing) model of the acquisition of the past tense in English which successfully maps many stems onto their past tense forms, both regular (walk/walked) ..."

Eliciting self-explanations improves understanding

by Michelene T. H. Chi, Nicholas De Leeuw, Mei-hung Chiu, Christian Lavancher - Cognitive Science , 1994
"... Learning involves the integration of new information into existing knowledge. Generoting explanations to oneself (self-explaining) facilitates that integration process. Previously, self-explanation has been shown to improve the acquisition of problem-solving skills when studying worked-out examples. ..."

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 ..."

removed from that vision. This is due to three main problems: (1) the notion of context is still ill defined; (2) there is a lack of conceptual models and methods to help drive the design of context-aware applications; and (3) no tools are available to jump-start the development of context
