A Numerical Scheme for the Quantum Boltzmann Equation Efficient in the Fluid Regime
Numerical Scheme Quantum Boltzmann Equation Efficient
2010/12/8
Numerically solving the Boltzmann kinetic equations with the small Knudsen number is challenging due to the stiff nonlinear collision term. A class of asymptotic preserving schemes
was introduced in ...
A generalized backwards scheme for solving non monotonic stochastic recursions
Stochastic recursions Stationary solutions Enriched probability space
2010/12/1
We propose an explicit construction of a stationary solution for a stochastic recursion of the form X ◦q = j(X) on a partially-ordered Polish space, when the monotonicity of j is not assumed. Un...
A symmetrized conjugacy scheme for orthogonal expansions
orthogonal expansions conjugacy Riesz transforms conjugate Poisson integra
2010/12/2
We establish a symmetrization procedure in a context of general orthogonal expansions associated with a second order differential operator L, a ‘Laplacian’. Combined with a unified conjugacy scheme fu...
In this paper a secret sharing scheme based on the word prob-lem in groups is introduced. The security of the scheme and possible variations are discussed in section 2. The article concludes with the ...
Cirrus clouds in a global climate model with a statistical cirrus cloud scheme
Cirrus clouds a global climate model a statistical cirrus cloud scheme
2010/8/13
A statistical cirrus cloud scheme that accounts for mesoscale temperature perturbations is implemented in a coupled aerosol and atmospheric circulation model to better represent both subgrid-scale sup...
The Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) for estimation of land surface heat fluxes
Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) estimation land surface heat fluxes
2010/4/7
A Two-layer Surface Energy Balance Parameterization Scheme (TSEBPS) is proposed for the estimation of surface heat fluxes using Thermal Infrared (TIR) data over sparsely vegetated surfaces. TSEBPS is ...
Passive scheme with a photon-number-resolving detector for decoy-state quantum key distribution with an untrusted source
photon-number-resolving decoy-state quantum
2010/3/10
A passive scheme with a photon-number-resolving (PNR) detector and a beam splitter which are used to monitor the statistical characteristics of photon source, is proposed to verify the security of vac...
New scheme to provide £1.3 m extra funding to students for high cost training in animal physiology
£ 1.3 m extra funding high cost training animal physiology
2010/1/27
From today (25 January), research institutions with PhD students funded by the Medical Research Council (MRC) or Biotechnology and Biological Sciences Research Council (BBSRC) can apply for additional...
A Novel Scheme to Search for Fractional Charge Particles in Low Energy Accelerator Experiments
Fractional Charge Particles Low Energy Accelerator Experiments
2010/3/15
In the Standard Model of particle physics, the quarks have fractional charge equal to $\pm1/3$ or $\pm2/3$ of the electron's charge. There have been a large number of experiments in searching for frac...
An explicit finite difference scheme for a compressible Heisenberg chain equations
compressible Heisenberg chain equations explicitness
2010/9/14
In this paper, we consider a class of compressible Heisenberg chain equations with periodic initial value problem. An explicit finite difference scheme is proposed. Moreover, its convergence and stabi...

Land-atmosphere interactions high resolution atmospheric simulation data assimilation scheme
2009/12/8
A valid tool for the retrieving of the turbulent fluxes that characterize the surface energy budget is constituted by the remote sensing of land surface states. In this study sequences of satellite-de...
A consistent molecular hydrogen isotope chemistry scheme based on an independent bond approximation
