1 Hu, Helen H.; Creem, Sarah H.; Gooch, Amy A.; Thompson, William B.Visual cues for perceiving distances from objects to surfaces (Abstract)An accurate perception of the distance between an object and a nearby surface can increase a viewer?s sense of presence in an immersive environment, particularly when a user is performing actions that affect or are affected by this distance. Two experiments were conducted examining the effectiven...Distance perception; immersive environment2002-02-03

Look for file "pci_pvs_files.tag.gz" in the TR directory.Bus transaction; Ordering problem1999
3 Sikorski, KrisA note on optimal algorithms for fixed pointsWe present a constructive lemma that we believe will make possible the design of nearly optimal 0(dlog | ) cost algorithms for computing eresidual approximations to the fixed points of d-dimensional nonexpansive mappings with respect to the infinity norm. This lemma is a generalization of a two-...Fixed points; Constructive lemma2009

5 Parker, Steven G.; Johnson, Christopher R.Interactive manipulation of contour data using the layers programThe "layers" program is useful for visualizing and editing large sets of contour data. These datasets arise frequently when trying to extract geometry from MRI slices. Due to the imprecise nature of the MR imaging and segmentation processes, the contours extracted may not accurately reflect the huma...Contour data; Layers program; MRI slices1994
6 Kniss, Joe; Ikits, Milan; Lefohn, Aaron; Hansen, Charles D.Closed-form approximations to the volume rendering integral with Gaussian transfer functionsIn direct volume rendering, transfer functions map data points to optical properties such as color and opacity. We have found transfer functions based on the Gaussian primitive to be particularly useful for multivariate volumes, because they are simple and rely on a limited number of free paramet...Volume rendering2003-07-25

9 Breaderson, Dean J.The I3Stick: an inexpensive, immersive, interaction deviceVirtual environments require interaction devices that are intuitive and ergonomic, yet capable of many input parameters. Many devices satisfying these requirements can be expensive, difficult to manipulate, and often require the integration of large software libraries with existing applications. We ...Virtual environments; I3Stick; Interaction devices1999
10 Riesenfeld, Richard F.Computer aided geometric designThis book contains the edited proceedings of the first International Conference on Computer Aided Geometric Design, an important new field that draws on the principles of computer science, mathematics, and geometric design. The list of contributors includes most of the leading researchers in the...Computer aided geometric design1973
11 Henderson, Thomas C.Reaction-diffusion processes as a computational paradigmTuring introduced reaction diffusion systems (RD-systems) as a mechanism which made possible the differentiation of morphological structure. We have shown how these systems can be used to provide an information network for smart sensor systems. However, we propose here that reaction diffusion system...Reaction diffusion systems; RD-systems; Computational paradigm2000
12 Henderson, Thomas C.Shortest paths in sensor snowWe propose to deploy and exploit a large number of non-mobile inexpensive distributed sensor and communication devices (called Smart Sensor Snow) to obtain information and guide mobile robots over a wide geographic area. Sensors may be of diverse physical natures: acoustic, IR, seismic, chemical, ma...Sensor snow; Distributed sensor; Smart Sensor Snow; Sensors1999
13 Michell, NickA gallium arsenide mutual exclusion elementA mutual exclusion element is a key component in building asynchronous and self-timed circuits. As part of our effort to design high performance self-timed circuits, we have designed a mutual exclusion element in gallium arsenide. This circuit has been fabricated in a 1.2? process and tested. A test...Mutual exclusion element; Self-timed circuits1993
14 Henderson, Thomas C.Agent-based engineering drawing analysisInterpretation of paper drawings has received a good deal of attention over the last decade. Related areas such as direct interpretation of human drawings (HCI), search and indexing of graphics databases, and knowledge representation in the domain of graphics and drawing understanding have also s...Interpretation; Human drawings; HCI; Graphic databases2002-02-04
15 Henderson, Thomas C.Apparent symmetries in range dataA procedure for extracting symmetrical features from the output of a range scanner is described which is insensitive to sensor noise and robust with respect to object surface complexity. The acquisition of symmetry descriptors for rigid bodies from a range image was in this case motivated by the ne...Symmetry descriptors; Range data; Range scanner; Dextrous manipulation systems1987
16 Henderson, Thomas C.Leadership protocol for S-NetsSmart Sensor Networks are collections of non-mobile devices (S-elements) which can compute, communicate and sense the environment; they must be able to create local groups of devices (S-cliques). We propose here a protocol to solve the leadership problems for S-Nets. We sketch the correctness of thi...Smart Sensor Networks; S-Nets2001
17 Boll, Steven F.Improving linear prediction analysis of noisy speech by predictive noise cancellationThe analysis of speech using Linear Prediction is reformulated to account for the presence of acoustically added noise and a technique is presented for reducing its effect on parameter estimation. The method, called Predictive Noise Cancellation (PNC), modifies the noisy speech autocorrelations ...Linear prediction; Predictive Noise Cancellation; Noisy speech; Sppech analysis1977
18 Shirley, Peter S.; Parker, Steven G.Single sample soft shadowsA simple extension to ray tracing is presented that creates visually plausible "soft" shadows with little extra computation. Although these soft shadows are approximate, they are robust and have penumbra widths that behave in a believable way, including accurate placement of singularities where penu...Soft shadows; Ray tracing; Penumbra width; Image generation1998
19 Brunvand, Erik L.Speed without fear: composable self-timed GaAs circuitsWe have designed a set of self-timed gallium arsenide building blocks that are suitable for composing into larger systems.

21 Cohen, ElaineA hole-filling algorithm for triangular meshesData obtained by scanning 3D models typically contains missing pieces and holes. These can be caused due to scanning artifacts or artifacts in the surface due to wear and tear. We provide a method based on the Moving Least Squares projection to fill holes in triangular meshes obtained during the ...Hole-filling algorithm; Triangular meshes; 3D models; Scanning2004-12-20
22 Henderson, Thomas C.Evolutionary teleomorphologyThe physical layout of organs and neural structures in biological systems is important to their functioning, and is the result of evolutionary selection forces. We believe this is true even at the individual neuron level, and should be accounted for in any bio-based approach. In particular, when tr...Evolutionary teleomorphology; Bio-based approach; Physical layout problem; PLP; Neurons; Nodes1995
23 Weinstein, DavidLocalization of multiple deep epileptic sources in a realistic head model via independent component analysisEstimating the location and distribution of current sources within the brain from electroencephalographic (EEG) recordings is an ill-posed inverse problem. The ill-posedness of the problem is due to a lack of uniqueness in the solution; that is, different configurations of sources can generate ident...EEG; Current sources; Head model2000
