Definition 3 (Polygonal Triangulation). Let K be a two-dimensional simplicial complex (i.e., a collection of triangles). If K is homeomorphic to a disk, then it is called a triangulation of a disk. Furthermore, if K is a k-gon divided by diagonals into k − 2 triangles, then K will be called a polygonal triangulation. See Figure 1. A k-gon dissected into k − 2 triangles will be called a k-triang...

We describe a method to approximate a closed surface triangulation using simulated annealing. Our approach guarantees that all vertices and triangles in an approximating surface triangulation are within a user-de ned distance of the original surface triangulation. We introduce the idea of atomic envelopes to guarantee error bounds that are independent of the surface geometry. Atomic envelopes a...

This article asserts that traditionally dominant models of health promotion in the US are fairly characterized by methodological individualism. This schema produces a focus on the individual as the node of intervention. Such emphasis results in a number of scientific and ethical problems. I identify three principal ethical deficiencies: first, the health promotions used are generally ineffectiv...

We introduce the restricted constrained Delaunay triangulation (restricted CDT). The restricted CDT generalizes the restricted Delaunay triangulation, allowing us to define a triangulation of a surface that includes a set of constraining segments. Under certain sampling conditions, the restricted CDT includes every constrained segment and suggests an algorithm that produces a triangulation of t...

A comprehensive uncertainty, baseline, and noise analysis in computing 3D points using a recent L1-based triangulation algorithm is presented. This method is shown to be not only faster and more accurate than its main competitor, linear triangulation, but also more stable under noise and baseline changes. A Monte Carlo analysis of covariance and a confidence ellipsoid analysis were performed ov...

AFSTRACT To PREPARE FUTI’RE INFORMATION PROFESSIONALS for the rapidly changing environment in which they will work, library and information science (LIS) educators have an obligation to ensure that their graduates understand, conceptually and pragmatically, the major methodological paradigms of research. Most LIS programs offer only a single course in research methods. Within that constraint, a...
