Using Visual Analytics to Maintain Situation Awareness in Astrophysics

Description: We present a novel collaborative visual analytics application for cognitively overloaded users in the astrophysics domain. The system was developed for scientists needing to analyze heterogeneous, complex data under time pressure, and then make predictions and time-critical decisions rapidly and correctly under a constant influx of changing data. The Sunfall Data Taking system utilizes severalnovel visualization and analysis techniques to enable a team of geographically distributed domain speci… more

A Visual Analytics Approach for Correlation, Classification, and Regression Analysis

Description: New approaches that combine the strengths of humans and machines are necessary to equip analysts with the proper tools for exploring today's increasing complex, multivariate data sets. In this paper, a novel visual data mining framework, called the Multidimensional Data eXplorer (MDX), is described that addresses the challenges of today's data by combining automated statistical analytics with a highly interactive parallel coordinates based canvas. In addition to several intuitive interaction ca… more

Guided Text Search Using Adaptive Visual Analytics

Description: This research demonstrates the promise of augmenting interactive visualizations with semi- supervised machine learning techniques to improve the discovery of significant associations and insights in the search and analysis of textual information. More specifically, we have developed a system called Gryffin that hosts a unique collection of techniques that facilitate individualized investigative search pertaining to an ever-changing set of analytical questions over an indexed collection of open-… more

Analytics for Cyber Network Defense.

Description: This report provides a brief survey of analytics tools considered relevant to cyber network defense (CND). Ideas and tools come from fields such as statistics, data mining, and knowledge discovery. Some analytics are considered standard mathematical or statistical techniques, while others reflect current research directions. In all cases the report attempts to explain the relevance to CND with brief examples.

Network Traffic Analysis With Query Driven VisualizationSC 2005HPC Analytics Results

Description: Our analytics challenge is to identify, characterize, and visualize anomalous subsets of large collections of network connection data. We use a combination of HPC resources, advanced algorithms, and visualization techniques. To effectively and efficiently identify the salient portions of the data, we rely on a multi-stage workflow that includes data acquisition, summarization (feature extraction), novelty detection, and classification. Once these subsets of interest have been identified and aut… more

Graph Generator Survey

Description: The benchmarking effort within the Extreme Scale Systems Center at Oak Ridge National Laboratory seeks to provide High Performance Computing benchmarks and test suites of interest to the DoD sponsor. The work described in this report is a part of the effort focusing on graph generation. A previously developed benchmark, SystemBurn, allowed the emulation of dierent application behavior profiles within a single framework. To complement this effort, similar capabilities are desired for graph-centr… more

Calculation of Particle Bounce and Transit Times on General Geometry Flux Surfaces

Description: A viable nuclear fusion reactor must confi ne energetic plasmas long enough so that the fusion energy produced exceeds the energy consumed to heat the plasma and maintain confi nement. It is well-known that magnetohydrodynamic (MHD) or plasma fl uid instabilities limit confi nement. One such important instability is the resistive wall mode (RWM). Plasma rotation faster than a critical frequency has been observed to stabilize the RWM. Some theories predict that the critical frequency will vary i… more
