Representation for Dynamic Situation Modeling

by unknown authors
"... In dynamic situation modeling we do not know at design time all the entities in a situation, their types, or the relationships in which they participate. We present a status report on JPF, a Framebased probabilistic representation and reasoning system with embedded support for hypotheses about the s ..."

Understanding Interactive Dynamic Situations

by Jérôme Thoméré , Simon King , Sophie Motet , François Arlabosse
"... Abstract The system presented here is developed to interpret dynamic situations involving several moving objects in a known environment. It is part of the ESPRIT VIEWS project and processes data coming from sequences of video frames. These numerical data are interpreted to identify in real-time sit ..."

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 ..."

Feedforward Control in Dynamic Situations

by Björn Johansson , 2003
"... This thesis proposal discusses control of dynamic systems and its relation to time. Although much research has been done concerning control of dynamic systems and decision making, little research exists about the relationship between time and control. Control is defined as the ability to keep a targ ..."

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 ..."

Dynamo: A Transparent Dynamic Optimization System

by Vasanth Bala, Evelyn Duesterwald , Sanjeev Banerjia - ACM SIGPLAN NOTICES , 2000
"... We describe the design and implementation of Dynamo, a software dynamic optimization system that is capable of transparently improving the performance of a native instruction stream as it executes on the processor. The input native instruction stream to Dynamo can be dynamically generated (by a JIT ..."

Fusion Metrics for Dynamic Situation Analysis

by Erik P. Blasch, Mike Pribilski, Brian Daughtery, Brian Roscoe, Josh Gunsett - Proceedings SPIE, Signal Processing, Sensor Fusion, and Target Recognition XIII,5429 , 2004
"... To design information fusion systems, it is important to develop metrics as part of a test and evaluation strategy. In many cases, fusion systems are designed to (1) meet a specific set of user information needs (IN), (2) continuously validate information pedigree and updates, and (3) maintain this ..."
Abstract - Cited by 17 (13 self) - Add to MetaCart

UCSF Chimera—a visualization system for exploratory research and analysis

by Eric F. Pettersen, Thomas D. Goddard, Conrad C. Huang, Gregory S. Couch, Daniel M. Greenblatt, Elaine C. Meng, Thomas E. Ferrin - J. Comput. Chem , 2004
"... Abstract: The design, implementation, and capabilities of an extensible visualization system, UCSF Chimera, are discussed. Chimera is segmented into a core that provides basic services and visualization, and extensions that provide most higher level functionality. This architecture ensures that the ..."

session interactively despite being at separate locales. Other extensions include Multalign Viewer, for showing multiple sequence alignments and associated structures; ViewDock, for screening docked ligand orientations; Movie, for replaying molecular dynamics trajectories; and Volume Viewer, for display

Routing in a Delay Tolerant Network

by Sushant Jain, Kevin Fall, Rabin Patra , 2004
"... We formulate the delay-tolerant networking routing problem, where messages are to be moved end-to-end across a connectivity graph that is time-varying but whose dynamics may be known in advance. The problem has the added constraints of finite buffers at each node and the general property that no con ..."

Network Coding for Large Scale Content Distribution

by Christos Gkantsidis, Pablo Rodriguez Rodriguez
"... We propose a new scheme for content distribution of large files that is based on network coding. With network coding, each node of the distribution network is able to generate and transmit encoded blocks of information. The randomization introduced by the coding process eases the scheduling of bloc ..."

We study the performance of network coding in heterogeneous networks with dynamic node arrival and departure patterns, clustered topologies, and when incentive mechanisms to discourage free
