THE EFFECTS OF MANDATORY SEAT BELT LAWS ON DRIVING BEHAVIOR AND TRAFFIC FATALITIES
DRIVING BEHAVIOR TRAFFIC FATALITIES
2015/7/17
This paper investigates the effects of mandatory seat belt laws on driver behavior and trafŽ c fatalities. Using a unique panel data set on
seat belt usage in all U.S. jurisdictions, we analyze ...
A CONSERVATIVE MESH-FREE SCHEME AND GENERALIZED FRAMEWORK FOR CONSERVATION LAWS

2015/7/3
We present a novel mesh-free scheme for solving partial differential equations. We first derive a conservative and stable formulation of mesh-free first derivatives. We then show tha...
An Edge-Averaged Semi-meshless Framework for Numerical Solution of Conservation Laws
Edge-Averaged Semi-meshless Framework Numerical Solution Conservation Laws
2015/7/3
Despite the continuous improvement of technology, generation of high-quality meshes around complicated geometry remains a time consuming and even laborious task. In this paper, we propose a semi-meshl...

2015/6/17
Curvelets provide a new multiresolution representation with several features that set them apart from existing representations such as wavelets, multiwavelets, steerable pyramids, and so on. They are ...
The scaling in the overlap region of turbulent wall-bounded flows has long been the source of
controversy, and until recently this controversy could not be addressed because measurements
did n...

Global Warming Species Extinction Ecology Power-Laws Species Variability Model
2013/2/26
A model based on Watson’s power law for the species-area relationship predicts that full global warming, projected up to the year 2050, could provoke the disappearance of roughly one-quarter of existi...
Scaling laws prediction from a solvable model of turbulent thermal convection
Turbulent flows, convection and heat transfer Turbulence simulation and modeling
2011/8/31
A solvable turbulent model is used to predict both the structure of the boundary layer and the scaling laws in thermal convection. The transport of heat depends on the interplay between the thermal, v...
