2015/6/1
This paper presents an approach to process raw lidar 3-D point clouds over urban area and extract terrain, buildings and other urban
features. In the initial step, “non-ground points” are separated ...

2014/12/22
The use of SU(3) chiral perturbation theory in the analysis of low energy meson-baryon interactions is discussed. It is emphasized that short distance effects, arising from propagation of Goldstone bo...

2010/6/30
We establish a systematic way to calculate multiloop amplitudes of infrared safe massless models with Implicit Regularization (IR), with a direct cancelation of the fictitious mass introduced by the p...
The effect of subfilter-scale physics on regularization models
subfilter-scale Lagrangian-averaged Navier-Stokes alpha-model magnetohydrodynamics
<
2010/4/6
The subfilter-scale (SFS) physics of regularization models are investigated to understand the regularizations' performance as SFS models. The strong suppression of spectrally local SFS interactions an...
Regularization parameters for the self-force of a scalar particle in a general orbit about a Schwarzschild black hole

2010/3/18
The interaction of a charged particle with its own field results in the "self-force" on the particle, which includes but is more general than the radiation reaction force. In the vicinity of the parti...
