Visualizing Election Polls
A New, Animated, Interactive Way to Analyze Opinion Data Media Contacts
Oct. 6, 2008 - Do you want to know the percentage of white women who support vice presidential candidate Sarah Palin? What about college-educated versus high school-educated white women? Or those who also hunt?
University of Utah computer scientists have written software they hope eventually will allow news reporters and citizens to easily, interactively and visually answer such questions when analyzing election results, political opinion polls or other surveys.
NVIDIA Recognizes University Of Utah as a CUDA Center Of Excellence
University of Utah Latest in a Growing List of Exceptional Schools Demonstrating Pioneering Work in Parallel Computing
Santa Clara, CA & Salt Lake City, UT - July 31, 2008 - NVIDIA Corporation, the worldwide leader in visual computing technologies, and the University of Utah today announced that the university has been recognized as a CUDA Center of Excellence, a milestone that marks the beginning of a significant partnership between the two organizations.
Friends of Gene Golub gathered at Chris Johnson's and Kate Coles' home on February 29, 2008 to remember Gene.

The February 2008 Issue of Salt Lake magazine includes a profile of groundbreaking research being conducted at the University of Utah on the problem of Autism. Advancements in brain image analysis techniques developed by SCI researchers Guido Gerig, Ross Whitaker and P. Thomas Fletcher are specifically mentioned. (print version only)
Announcing VisTrails 1.0
Fig 1: The VisTrails history tree contains a node for each version of a workflow (or pipeline) as it evolves over time. This results in a complete audit trail of the steps that were taken in a computational task.
VisTrails is a new system that provides data and process management support for exploratory computational tasks. It combines features of both workflow and visualization systems. Like many workflow systems, it enables seamless integration of loosely-coupled resources such as specialized libraries, grid, and web services. Likewise, it parallels some visualization systems by providing a mechanism to perform parameter explorations and result comparisons. But unlike these systems, VisTrails was designed to manage exploratory activities, where computational tasks are iteratively refined as users formulate and test hypotheses. A key distinguishing feature of VisTrails is a comprehensive provenance infrastructure that maintains detailed history information about the steps followed and data derived in the course of an exploratory task. VisTrails leverages this information to provide novel operations and user interfaces that streamline this process.
The paper "Querying and Creating Visualizations by Analogy", by Carlos E. Scheidegger, Huy T. Vo, David Koop, Juliana Freire, and Cláudio Silva was selected as the "Best Paper" at IEEE Visualization 2007. In this paper, the authors introduce a new framework that allows users who are not necessarily programmers to query and refine pipelines (or workflows) by analogy. They describe a query-by-example interface which allows users to construct as complex, structure-based queries (e.g., find workflows that resample a data set before extracting an isurface) by example, using the same interface used to build pipelines. They also introduce analogy as a first-class operation to create and refine pipelines. The analogy operation allows casual users to modify pipelines without having to directly edit their definitions. These features have been implemented in their open-source workflow and provenance management system called VisTrails, which can be downloaded from the SCI Website.
Steve Parker Selected Member of DARPA Computer Science Study Group
Dr. Steve Parker has been selected by the Pentagon's Defense Advanced Research Projects Agency (DARPA) to be a member of the 2008 DARPA . The program supports university researchers with research grants for up to three years, while informing them of the Department of Defense's information technology needs and priorities. Dr. Parker will receive $100,000 the first year, and potentially as much as $750,000 during the second and third years.
CIBC Collaborator Mario Capecchi Wins Nobel Prize
The NIH Center for Integrative Biomedical Computing (CIBC) and the Scientific Computing and Imaging (SCI) Institute would like to join the international scientific community in extending our heartiest congratulations to our University of Utah colleague Dr. Mario Capecchi as one of the three recipients of the 2007 Nobel Prize in Physiology or Medicine. This award recognizes the ground-breaking work of Dr. Capecchi and his scientific contemporaries, Dr. Oliver Smithies of Cardiff University in the UK and Dr. Martin Evans of the University of North Carolina at Chapel Hill, in the development of genetic targeting of embryonic stem cells in mice. This novel technique selectively alters individual genes in the mouse DNA. Through studies employing genetic targeting, medical researchers now can better elucidate the roles that particular genes play in the animal development. The application of this method has revolutionized the study of mammalian biology and contributed to the development of new animal models for numerous human diseases in addition to cancers occurring in mice.
