Indifferentiability of Confusion-Diffusion Networks
Indifferentiability Confusion-Diffusion Networks
2016/1/22
We show the first positive results for the indifferentiability security of the confusion-diffusion networks (which are extensively used in the design of block ciphers and hash functions).In particular...
DynaDiffuse: A Dynamic Diffusion Model for Continuous Time Constrained Influence Maximization
A Dynamic Diffusion Model Constrained Influence Maximization
2016/1/22
Studying the spread of phenomena in social networks is critical but still not fully solved. Existing influence max-imization models assume a static network, disregarding its evolution over time. We in...
Energy stable flux reconstruction schemes for advection–diffusion problems
High-order Unstructured Discontinuous Galerkin
2015/7/3
High-order methods for unstructured grids provide a promising option for solving chal lenging problems in computational fluid dynamics. Flux reconstruction (FR) is a framework which unifie...

High-order Discontinuous Galerkin Spectral difference
2015/7/3
The Flux Reconstruction (FR) approach unifies several well-known high-order schemes for unstructured grids, including a collocation-based nodal discontinuous Galerkin (DG) method and all types o...
EFFECT OF ARTIFICIAL DIFFUSION SCHEMES ON MULTIGRID CONVERGENCE
EFFECT ARTIFICIAL DIFFUSION SCHEMES MULTIGRID CONVERGENCE
2015/7/1
The effect of artificial diffusion schemes on the convergence of an implicit method is investi-gated. A multigrid code using a symmetric lim-ited positive scheme in conjunction with a lower-upper symm...
Artificial Diffusion, Upwind Biasing, Limiters and their Effect on Accuracy and Multigrid Convergence in Transonic and Hypersonic Flows
Artificial Diffusion, Upwind Biasing, Limiters Accuracy Multigrid Convergence Transonic Hypersonic Flows
2015/7/1
The theory of non-oscillatory scalar schemes is developed in this paper in terms of the local extremum diminishing (LED) principle that maxima should not increase and minima should not decrease.
Heavy-Quark Diffusion and Hadronization in Quark-Gluon Plasma
Heavy-Quark Diffusion Hadronization Quark-Gluon Plasma
2011/6/29
We calculate diffusion and hadronization of heavy quarks in high-energy heavy-ion collisions implementing the notion of a strongly coupled quark-gluon plasma in both micro- and macroscopic components....
On the Dynamics of Human Proximity for Data Diffusion in Ad-Hoc Networks

2011/6/29
We report on a data-driven investigation aimed at understanding the dynamics of mmessage spreading in a real-world dynamical network of human proximity. We use
data collected by means of a proximity-...
Experimenting with Immediate Re-Routing on an Information-Diffusion-Based Routing Test-Bed
Networks Networks,assignment routing algorithms
2011/5/21
We propose an immediate re-routing (IRR) extension to RSVP-TE signaling and implement it on our IDBR test-bed. By allowing wavelength conversion during the re-routing process, the proposed scheme can ...

2011/1/24
Micro-structure related behavior of diffusion bonding joints is a crucial issue in device and reactor fabrication of Micro Chemo Mechanical Systems. However, the previous studies have been focused on ...
An Information-Diffusion-Based Routing Scheme in Wavelength-Routed WDM Mesh Networks
Networks Networks assignment routing algorithms
2010/6/5
We propose a novel information-diffusion-based routing (IDBR) scheme in wavelength routed WDM mesh networks. The IDBR scheme has the fast convergence and the low bandwidth consumption of OSPF-TE while...
