Marching cubes: A high resolution 3D surface construction algorithm
 COMPUTER GRAPHICS
, 1987
"... We present a new algorithm, called marching cubes, that creates triangle models of constant density surfaces from 3D medical data. Using a divideandconquer approach to generate interslice connectivity, we create a case table that defines triangle topology. The algorithm processes the 3D medical d ..."

ReTiling Polygonal Surfaces
 Computer Graphics
, 1992
"... This paper presents an automatic method of creating surface models at several levels of detail from an original polygonal description of a given object. Representing models at various levels of detail is important for achieving high frame rates in interactive graphics applications and also for speed ..."

This paper shows how a new set of vertices can be distributed over the surface of a model and connected to one another to create a retiling of a

Safely Unobstructing the Urethra
"... ■ When admitting young male cats in a medical crisis, always assess urinary bladder size. Cats with severe and prolonged urethral obstruction are depressed and dehydrated, and rarely present with signs referable to the urinary tract. ■ Remember the S.A.F.E. approach (Stabilize first, Accurate diag ..."

■ When admitting young male cats in a medical crisis, always assess urinary bladder size. Cats with severe and prolonged urethral obstruction are depressed and dehydrated, and rarely present with signs referable to the urinary tract. ■ Remember the S.A.F.E. approach (Stabilize first, Accurate diagnosis, Flush, don’t force, Extend the urethra caudally) for removing urethral obstructions in male cats. ■ Determining the cause of urethral obstruction is essential for developing an appropriate therapeutic plan to alleviate obstruction and recommend appropriate measures to prevent recurrence.
An Approximate MaxFlow MinCut Theorem for Uniform Multicommodity Flow Problems with Applications to Approximation Algorithms
, 1989
"... In this paper, we consider a multicommodity flow problem where for each pair of vertices, (u,v), we are required to sendf halfunits of commodity (uv) from u to v and f halfunits of commodity (vu) from v to u without violating capacity constraints. Our main result is an algorithm for performing th9 ..."

, 2004
"... Abstract. To perform surveillance tasks effectively, unobstructed views of objects are required e.g. unobstructed video of objects are often needed for gait recognition. As a result, we need to determine intervals for video collection during which a desired object is visible w.r.t. a given sensor. I ..."

Network Robustness and Fragility: Percolation on Random Graphs.
 Physical Review Letters
, 2000
"... Recent work on the Internet, social networks, and the power grid has addressed the resilience of these networks to either random or targeted deletion of network nodes or links. Such deletions include, for example, the failure of Internet routers or power transmission lines. Percolation models on ra ..."

Recognizing depthrotated objects: Evidence and conditions for threedimensional viewpoint invariance

Five experiments on the effects of changes of depth orientation on (a) priming the naming of briefly flashed familiar objects, (b) matching individual sample volumes (geons), and (c) classifying unfamiliar objects (that could readily be decomposed into an arrangement of distinctive geons) all reveal ..."

The viewer readily appreciates that it shows two different views of the same object, despite myriad differences in the two silhouettes and in the local image features (namely, vertices, lines, and length and curvature of these lines).
