A Hybrid Variational Front Tracking-Level Set Mesh Generator For Problems Exhibiting Large Deformations and Topological Changes
Front Tracking Arbitrary-Lagrangian-Eulerian Mesh Method
2015/12/11
We present a method for generating 2-D unstructured triangular meshes that undergo large deformations and
topological changes in an automatic way. We employ a method for detecting when topological ch...
The Skewes number for twin primes: counting sign changes of $π_2(x)-C_2 \Li_2(x)$
Primes twins Skewes number Number Theory
2011/9/6
Abstract: The results of the computer investigation of the sign changes of the difference between the number of twin primes $\pi_2(x)$ and the Hardy--Littlewood conjecture $C_2\Li_2(x)$ are reported. ...
Detecting changes in functional linear models
functional data projections weak dependence change point weak convergence
2011/6/15
We observe two sequences of curve which are connected via an integral operator. Our model includes linear models as well as autoregressive models in Hilbert spaces. We wish to test the null hypothesis...
Order flow dynamics around extreme price changes on an emerging stock market
Order flow dynamics price changes emerging stock market
2010/4/27
We study the dynamics of order flows around large intraday price changes using ultra-high-frequency data from the Shenzhen Stock Exchange. We find a significant reversal of price for both intraday pri...
Controlling Effect of Geometrically Defined Local Structural Changes on Chaotic Hamiltonian Systems
Chaotic Hamiltonian Systems Local Structural Changes
2010/4/1
An effective characterization of chaotic conservative Hamiltonian systems in terms of the curvature associated with a Riemannian metric tensor derived from the structure of the Hamiltonian has been ex...
Productivity changes of the wood product manufacturing sector in the U.S.
Data Envelopment Analysis productivity change wood industry
2010/9/10
The wood product manufacturing is one of the important manufacturing industries in the United
States. Similar to other manufacturing industries, it has been facing many challenges including
an incre...
