1 Johnson, Robert R.Patterns of patternsPurpose of this Poster is to demonstrate that it takes the patterns of values in all the many dimensions to place each patient in the final patterns shown in each of the 5 charts. The final patterns determine the ability of each technology to identify or distinguish patients in each class. It is p...Gene patterns; Colon cancer; Trapeze Interactive poster2010-03-15
2 Venkatasubramanian, SureshEfficient protocols for distributed classification and optimizationA recent paper [1] proposes a general model for distributed learning that bounds the communication required for learning classifiers with e error on linearly separable data adversarially distributed across nodes. In this work, we develop key improvements and extensions to this basic model. Our first...2012-01-01
3 Hansen, Charles D.Recent developments in parallel renderingUsing parallel computers for computer graphics rendering dates back to the late 1970s. Several papers published then focused on image space decompositions for theoretical parallel machines. Early research concentrated on algorithmic studies and special-purpose hardware, but the growing availability...Parallel rendering; Massively parallel processors1994
4 Hansen, Charles D.Reconstruction and visualization of planetary nebulaeAbstract-From our terrestrially confined viewpoint, the actual three-dimensional shape of distant astronomical objects is, in general, very challenging to determine. For one class of astronomical objects, however, spatial structure can be recovered from conventional 2D images alone. So-called planet...2005-09
5 Hansen, Mark S.; Healy, Lindsey J.; Johnson, Christopher R.; Capecchi, Mario R.; Keller, Charles; Jones, Greg M.Virtual histology of transgenic mouse embryos for high-throughput phenotyping.A bold new effort to disrupt every gene in the mouse genome necessitates systematic, interdisciplinary approaches to analyzing patterning defects in the mouse embryo. We present a novel, rapid, and inexpensive method for obtaining high-resolution virtual histology for phenotypic assessment of mouse ...Forkhead Transcription Factors; Paired Box Transcription Factors2006
6 Freire, Juliana; Silva, Claudio T.Provenance for computational tasks: a surveyThe problem of systematically capturing and managing provenance for computational tasks has recently received significant attention because of its relevance to a wide range of domains and applications. The authors give an overview of important concepts related to provenance management, so that poten...Provenance management; Computational tasks2008-05
7 Bhanu, BirSegmentation of images having unimodal distributionsA gradient relaxation method based on maximizing a criterion function is studied and compared to the nonlinear probabilistic relaxation method for the purpose of segmentation of images having unimodal distributions. Although both methods provide comparable segmentation results, the gradient method h...Gradient relaxation method; Image segmentation; Segmentation algorithm1982
8 Bhanu, BirShape matching of two-dimensional objectsIn this paper we present results in the areas of shape matching of nonoccluded and occluded two-dimensional objects. Shape matching is viewed as a "segment matching" problem. Unlike the previous work, the technique is based on a stochastic labeling procedure which explicitly maximizes a criterion ...Shape matching; Two-dimensional objects; Segment matching1984
9 Freire, JulianaSiphoning hidden-web data through keyword-based interfacesIn this paper, we study the problem of automating the retrieval of data hidden behind simple search interfaces that accept keyword-based queries. Our goal is to automatically retrieve all available results (or, as many as possible). We propose a new approach to siphon hidden data that automatically ...2004-01-01
10 Gouraud, HenriComputer display of curved surfacesThis research describes a method for producing shaped pictures of curved surfaces. It uses a small polygon approximation of the surface to solve efficiently the nidden parts detection, and then computes the shading on each polygon in such a way that visual discontinuities between adjacent polygons d...Curved surfaces; Computer display1971
11 Kirby, Robert MichaelStochastic collocation for optimal control problems with stochastic pde constraintsWe discuss the use of stochastic collocation for the solution of optimal control problems which are constrained by stochastic partial differential equations (SPDE). Thereby the constraining SPDE depends on data which is not deterministic but random. Assuming a deterministic control, randomness withi...2012-01-01
12 Evans, DavidDisplay of complex three dimensional finite element modelsComplex three dimensional models can be displayed after an automatic generation of a finite element (panel) mapping. although this automatic generation algorithm fails at certain levels of model complexity, the elimination of these failures can be accomplished through user interaction. This report p...Three dimensional models; Finite element models1978
