Multi-channel search for squarks and gluinos in sqrt(s)=7 TeV pp collisions with the ATLAS detector
ATLAS Collaboration
A search for supersymmetric particles in final states with zero, one, and two leptons, with and without jets identified as originating from b-quarks, in 4.7 fb-1 of sqrt(s)=7 TeV p…
Discrete Surface Modeling Based on Google Earth: A Case Study
Gang Mei, John C. Tipper, Nengxiong Xu
Google Earth (GE) has become a powerful tool for geological, geophysical and geographical modeling; yet GE can be accepted to acquire elevation data of terrain. In this paper, we p…
A Hybrid Approach for Optimizing Planar Triangular Meshes
Gang Mei, John C. Tipper, Nengxiong Xu
Modified Direct Method (MDM) is an iterative scheme based on Jacobi iterations for smoothing planar meshes [4]. The basic idea behind MDM is to make any triangular element be as cl…
An Algorithm for Finding Convex Hulls of Planar Point Sets
Gang Mei, John C. Tipper, Nengxiong Xu
This paper presents an alternate choice of computing the convex hulls (CHs) for planar point sets. We firstly discard the interior points and then sort the remaining vertices by x-…
Ear-clipping Based Algorithms of Generating High-quality Polygon Triangulation
Gang Mei, John C. Tipper, Nengxiong Xu
A basic and an improved ear clipping based algorithm for triangulating simple polygons and polygons with holes are presented. In the basic version, the ear with smallest interior a…
T-Base: A Triangle-Based Iterative Algorithm for Smoothing Quadrilateral Meshes
Gang Mei, John C. Tipper, Nengxiong Xu
We present a novel approach named TBase for smoothing planar and surface quadrilateral meshes. Our motivation is that the best shape of quadrilateral element (square) can be virtua…
