A proposed Computer-assisted Graphics-based instruction scheme for Stochastic Theory

by Faisal Hossain, David Huddleston - in Hydrological Sciences,” Computers in Education Journal. Vol. XVII , 2007
"... We describe the initial concept for a computer-assisted instruction strategy that can be developed to improve the current state of learning in the classroom of the following two topics in geoscience education: (1) stochastic theory in hydrologic sciences; and (2) the role of hydrologic process contr ..."

for this purpose. Through our proposed end-to-end graphics-based instruction system, students are expected to learn more effectively the following: (1) the implications of applying alternative stochastic theories on the simulation end-product (i.e., stream-flow from hydrologic models driven by satellite rainfall

Self-Explanatory Simulations : An integration of qualitative and quantitative knowledge

by Kenneth D. Forbus - Proceedings ofAAAI-90 , 1990
"... A central goal of qualitative physics is to provide a framework for organizing and using quantitative knowl-edge. One important use of quantitative knowledge is numerical simulation. While current numerical simula-tors are powerful, they are often hard to construct, do not reveal the assumptions und ..."

provide the accuracy of numerical models and the interpretive power of qualitative reasoning. We de-fine what self-explanatory simulations are and show how to construct them automatically. We illustrate their power with some examples generated with an imple-mented system, SIHGEN. We analyze

False Data Injection Attacks against State Estimation in Electric Power Grids

by Yao Liu, Peng Ning, Michael K. Reiter , 2009
"... A power grid is a complex system connecting electric power generators to consumers through power transmission and distribution networks across a large geographical area. System monitoring is necessary to ensure the reliable operation of power grids, and state estimation is used in system monitoring ..."

PixelFlow: High-Speed Rendering Using Image Composition

by Steven Molnar, John Eyles, John Poulton - Computer Graphics (Proc. SIGGRAPH , 1992
"... We describe PixelFlow, an architecture for high-speed image generation that overcomes the transformation- and frame-buffer– access bottlenecks of conventional hardware rendering architectures. PixelFlow uses the technique of image composition: it distributes the rendering task over an array of ident ..."

can be coupled to a parallel supercomputer to serve as an immediatemode graphics server, or it can maintain a display list for retainedmode rendering. The PixelFlow design has been simulated extensively at high level. Custom chip design is underway. We anticipate a working system by late 1993.

Generating Network Topologies That Obey Power Laws

by Christopher R. Palmer, J. Gregory Steffan - In GLOBECOM , 2000
"... Recent studies have shown that Internet graphs and other network systems follow power-laws. Do artificial network topologies commonly used in network simulation studies obey these power-laws? In this paper we show that current topology generators do not obey all of the power-laws, and we present two ..."

Behavioral theories and the neurophysiology of reward,

by Wolfram Schultz - Annu. Rev. Psychol. , 2006
"... ■ Abstract The functions of rewards are based primarily on their effects on behavior and are less directly governed by the physics and chemistry of input events as in sensory systems. Therefore, the investigation of neural mechanisms underlying reward functions requires behavioral theories that can ..."

Management System Implementation for Distributed Power Generation

by Sumeth Anantasate, Chaimongkon Chokpanyasuwan, Woraratana Pattaraprakorn, Pornrapeepat Bhasaputra
"... When power demand is foreseen to rapidly increase in near future, the need to upgrade the electrical sys-tem / equipment becomes apparent. When operation must proceed while any change is in progress, the revision is very difficult. Parallel operation of electri-cal equipment of various vintages and ..."
Abstract - Add to MetaCart
. The approach simulates creativity of the team member to generate new ideas. As a result of this study, numerous and qualitative recommendations have been made to elec-trical design the safety and operability problem out of the major power system upgrade. Among the recom-mendations are suggestions on protection
