How to shrinkwrap a critical point : an algorithm for the adaptive triangulation of iso-surfaces with arbitrary topology
No full textSHRINKWRAP: AN ADAPTIVE ALGORITHM FOR POLYGONIZING AN IMPLICIT SURFACE
No full textAn algorithm is presented which generates a triangular
mesh to approximate an equi-potential surface. The algorithm is
adaptive in the sense that the lengths of the sides of the triangles
in the mesh vary with the local curvature of the underlying surface.
A quantitative analysis of the accuracy of the algorithm is given
along with an empirical comparison with earlier algorithms.We are currently acquiring citations for the work deposited into this collection.

An Object-Oriented Interactive System for Scientific Simulations:Design and Applications
Get PDFBetter insight in complex physical processes requires integration of scientific visualization and numerical simulation in a single interactive framework. This paper presents an object-oriented environment which combines the tasks of numerical simulation, visualization, simulation specification, run-time monitoring and steering. We first review the different existing approaches to the above tasks and outline their relative limitations. Next, we present a model for a framework which attempts to provide a general approach to the tasks of simulation specification and steering in an object-oriented manner. An implementation of the framework is described. We have built an object-oriented library for finite element computations and integrated it into the simulation system. An example in which our system has been used to solve a practical engineering problem illustrates the combination of object-oriented numerics and interactivity

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
