In this paper, we will provide the the finite element method for the electro-osmotic flow in micro-channels, in which a convection-diffusion type equation is given for the charge density ρe. A time-di...
The asymptotic error floor of LDPC ensembles under BP decoding
Binary no memory random elements the noise
2015/8/21
We consider communication over binary memoryless symmetric channels using random elements from irregular low density parity check code (LDPC) ensembles, and belief propagation (BP) decoding. Under the...
Jacobi-type Gauss-Seidel Smoother with Error Compensation for Parallel Multigrid
parallel multigrid parallel Gauss-Seidel JGS JGSEC
2012/8/10
Smoother is the most important component of parallel multigrid methods, however,
the widely used Gauss-Seidel smoother is difficult to be parallelized. This paper
proposes a new parallel smoother, J...
An Error Estimate For a Plane Elasticity Problem and The Enhanced Assumed Strain Method
2D-elasticity enhanced strain method shear locking nonconforming element
2012/8/8
The method of enhanced assumed strains (EAS) is a popular tool for avoiding locking
phenomena, e.g., a remedy for shear locking in plane elasticity. We consider bending-dominated
problems and prove ...
