Designing a Collaborative Visual Analytics Tool for Social and Technological Change Prediction
Found in: IEEE Computer Graphics and Applications
By Pak Chung Wong, L. Ruby Leung, Ning Lu, Michael J. Scott, Patrick Mackey, Harlan Foote, James Correia Jr., Z. Todd Taylor, Jianhua Xu, Stephen D. Unwin, Antonio Sanfilippo
Issue Date:September 2009
pp. 58-68
GreenOracle is a collaborative visual analytics tool for interactively modeling future social and technological changes. The development project involves an interdisciplinary team of scientists from atmospheric physics, electrical engineering, building eng...
 
A Novel Visualization Technique for Electric Power Grid Analytics
Found in: IEEE Transactions on Visualization and Computer Graphics
By Pak Chung Wong, Kevin Schneider, Patrick Mackey, Harlan Foote, George Chin Jr., Ross Guttromson, Jim Thomas
Issue Date:May 2009
pp. 410-423
The application of information visualization holds tremendous promise for the electric power industry, but its potential has so far not been sufficiently exploited by the visualization community. Prior work on visualizing electric power systems has been li...
 
Graph Signatures for Visual Analytics
Found in: IEEE Transactions on Visualization and Computer Graphics
By Pak Chung Wong, Harlan Foote, George Chin Jr., Patrick Mackey, Ken Perrine
Issue Date:November 2006
pp. 1399-1413
<p><b>Abstract</b>—We present a visual analytics technique to explore graphs using the concept of a data signature. A data signature, in our context, is a multidimensional vector that captures the local topology information surrounding ea...
 
Dynamic Visualization of Graphs with Extended Labels
Found in: Information Visualization, IEEE Symposium on
By Pak Chung Wong, Patrick Mackey, Ken Perrine, James Eagan, Harlan Foote, Jim Thomas
Issue Date:October 2005
pp. 10
The paper describes a novel technique to visualize graphs with extended node and link labels. The lengths of these labels range from a short phrase to a full sentence to an entire paragraph and beyond. Our solution is different from all the existing approa...
 
Dynamic Visualization of Transient Data Streams
Found in: Information Visualization, IEEE Symposium on
By Pak Chung Wong, Harlan Foote, Dan Adams, Wendy Cowley, Jim Thomas
Issue Date:October 2003
pp. 13
We introduce two dynamic visualization techniques using multi-dimensional scaling to analyze transient data streams such as newswires and remote sensing imagery. While the time-sensitive nature of these data streams requires immediate attention in many app...
 
Global Visualization and Alignments of Whole Bacterial Genomes
Found in: IEEE Transactions on Visualization and Computer Graphics
By Pak Chung Wong, Kwong Kwok Wong, Harlan Foote, Jim Thomas
Issue Date:July 2003
pp. 361-377
<p><b>Abstract</b>—We present a novel visualization technique to align whole bacterial genomes with millions of nucleotides. Our basic design combines the descriptive power of pixel-based visualizations with the interpretative strength of...
 
Vector Fields Simplification - A Case Study of Visualizing Climate Modeling and Simulation Data Sets
Found in: Visualization Conference, IEEE
By Pak Chung Wong, Harlan Foote, Ruby Leung, Elizabeth Jurrus, Dan Adams, Jim Thomas
Issue Date:October 2000
pp. 36
In our study of regional climate modeling and simulation, we frequently encounter vector fields that are crowded with large numbers of critical points. A critical point in a flow is where the vector field vanishes. While these critical points accurately re...

TOPIC ISLANDS™ — A Wavelet-Based Text Visualization System
Found in: Visualization Conference, IEEE
By Nancy E. Miller, Pak Chung Wong, Mary Brewster, Harlan Foote
Issue Date:October 1998
pp. 189
We present a novel approach to visualize and explore unstructured text. The underlying technology, called TOPIC-O-GRAPHY™, applies wavelet transforms to a custom digital signal constructed from words within a document. The resultant multiresolution wavelet...
 
Organic data memory using the DNA approach
Found in: Communications of the ACM
By Harlan Foote, Kwong-kwok Wong, Pak Chung Wong
Issue Date:January 1988
pp. 95-98
For very long-term storage and retrieval, encode information as artificial DNA strands and insert into living hosts. As vectors, bacteria, even some bugs and weeds, might be good for hundreds of millions of years.
