Performance Bounds and Distance Spectra of Variable Length Codes in Turbo/Concatenated Systems
Abstract--Variable length codes (VLCs), used in data compression, are very sensitive to error propagation in the presence of noisy channels. Addressing this problem with joint sour...

Free-flowing granular materials with two-way solid coupling
We present a novel continuum-based model that enables efficient simulation of granular materials. Our approach fully solves the internal pressure and frictional stresses in a gran...

Boundary Handling and Adaptive Time-stepping for PCISPH
We present a novel boundary handling scheme for incompressible fluids based on Smoothed Particle Hydrodynamics (SPH). In combination with the predictive-corrective incompressible ...

Urban-X: Towards distributed channel assignment in cognitive multi-radio mesh networks
Researches about multi-radio mesh networks have mostly focused on channel allocation under internal interference. However, the deployment of WMNs in unlicensed bands of dense urban...
