ATTENTION, INTENTIONS, AND THE STRUCTURE OF DISCOURSE

by Barbara J. Grosz, Candace L. Sidner , 1986
"... In this paper we explore a new theory of discourse structure that stresses the role of purpose and processing in discourse. In this theory, discourse structure is composed of three separate but interre-lated components: the structure of the sequence of utterances (called the linguistic structure), a ..."

), a struc-ture of purposes (called the intentional structure), and the state of focus of attention (called the attentional state). The linguistic structure consists of segments of the discourse into which the utter-ances naturally aggregate. The intentional structure captures the discourse

Finding structure in time

by Jeffrey L. Elman - COGNITIVE SCIENCE , 1990
"... Time underlies many interesting human behaviors. Thus, the question of how to represent time in connectionist models is very important. One approach is to represent time implicitly by its effects on processing rather than explicitly (as in a spatial representation). The current report develops a pro ..."

of prior internal states. A set of simulations is reported which range from relatively simple problems (temporal version of XOR) to discovering syntactic/semantic features for words. The networks are able to learn interesting internal representations which incorporate task demands with memory demands

Virtual time and global states of distributed systems.

by Friedemann Mattern - Proc. Workshop on Parallel and Distributed Algorithms, , 1989
"... Abstract A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized \ r eal world" and helps to solve problems like getting a c ..."

Image Quality Assessment: From Error Visibility to Structural Similarity

by Zhou Wang, Alan C. Bovik, Hamid R. Sheikh, Eero P. Simoncelli - IEEE TRANSACTIONS ON IMAGE PROCESSING , 2004
"... Objective methods for assessing perceptual image quality have traditionally attempted to quantify the visibility of errors between a distorted image and a reference image using a variety of known properties of the human visual system. Under the assumption that human visual perception is highly adapt ..."
Abstract - Cited by 1499 (114 self) - Add to MetaCart
adapted for extracting structural information from a scene, we introduce an alternative framework for quality assessment based on the degradation of structural information. As a specific example of this concept, we develop a Structural Similarity Index and demonstrate its promise through a set

Crystallography & NMR system: A new software suite for macromolecular structure determination.

by Axel T Brünger , Paul D Adams , G Marius Clore , Warren L Delano , Piet Gros , Ralf W Grosse-Kunstleve , Jian-Sheng Jiang , John Kuszewski , Michael Nilges , Navraj S Pannu , Randy J Read , Luke M Rice , Thomas Simonson , Gregory L Warren - Acta Crystallogr. D Biol. Crystallogr. , 1998
"... Abstract A new software suite, called Crystallography & NMR System (CNS), has been developed for macromolecular structure determination by X-ray crystallography or solution nuclear magnetic resonance (NMR) spectroscopy. In contrast to existing structure determination programs the architecture o ..."

of CNS is highly flexible, allowing for extension to other structure determination methods, such as electron microscopy and solid state NMR spectroscopy. CNS has a hierarchical structure: a high-level hypertext markup language (HTML) user interface, task-oriented user input files, module files, a

The Theory of Hybrid Automata

by Thomas A. Henzinger , 1996
"... A hybrid automaton is a formal model for a mixed discrete-continuous system. We classify hybrid automata acoording to what questions about their behavior can be answered algorithmically. The classification reveals structure on mixed discrete-continuous state spaces that was previously studied on pur ..."

An algorithm for drawing general undirected graphs

by Tomihisa Kamada, Satoru Kawai - Information Processing Letters , 1989
"... Graphs (networks) are very common data structures which are handled in computers. Diagrams are widely used to represent the graph structures visually in many information systems. In order to automatically draw the diagrams which are, for example, state graphs, data-flow graphs, Petri nets, and entit ..."

Statecharts: A Visual Formalism For Complex Systems

by David Harel , 1987
"... We present a broad extension of the conventional formalism of state machines and state diagrams, that is relevant to the specification and design of complex discrete-event systems, such as multi-computer real-time systems, communication protocols and digital control units. Our diagrams, which we cal ..."
Abstract - Cited by 2704 (56 self) - Add to MetaCart
call statecharts, extend conventional state-transition diagrams with essentially three olements, dealing, respectively, with the notions of hierarchy, concurrency and communication. These transform the language of state diagrams into a highly structured' and economical description language

Monads for functional programming

by Philip Wadler , 1995
"... The use of monads to structure functional programs is described. Monads provide a convenient framework for simulating effects found in other languages, such as global state, exception handling, output, or non-determinism. Three case studies are looked at in detail: how monads ease the modification o ..."

A theory of type polymorphism in programming

by Robin Milner - Journal of Computer and System Sciences , 1978
"... The aim of this work is largely a practical one. A widely employed style of programming, particularly in structure-processing languages which impose no discipline of types, entails defining procedures which work well on objects of a wide variety. We present a formal type discipline for such polymorp ..."
