We establish normal forms for conformal vector fields on pseudo-Riemannian manifolds in the neighborhood of a singularity. For real-analytic Lorentzian manifolds, we show that the vector ʂ...
Marc Bloch et les crises du savoir.
The Weather Research and Forecasting meteorological (WRF) model has been coupled to the Soil–Plant–Atmosphere (SPA) terrestrial ecosystem model to produce WRF-SPA.
通过对超声速湍流边界层中横向声速喷流的计算,对一种混合大涡/雷诺平均Navier-Stokes(LES/RANS)模拟方法进行了测试,该方法采用一个依赖于到壁面的距离及当地湍流参数的混合函数结合两方程k-ω SST(shear stress transport)湍流模型和混合尺度亚格子模型来封闭湍流项.计算结果表明:混合模拟方法能够捕捉到喷流/湍流边界层相互干扰的非定常大尺度结构,且对分离区长度、...
Abstract: We pursue Arthur's invariant trace formula for certain coverings of connected reductive groups by deducing explicit formulas for its spectral side. This is based on some results in local har...
Abstract: We establish some results in local harmonic analysis which are necessary for Arthur's invariant trace formula for coverings of connected reductive groups. More precisely, for local coverings...
将两方程k-ω SST湍流模型和Sagaut的混合尺度亚格子模型通过一个混合函数相结合, 构造出一种混合大涡/雷诺平均N-S方程模拟方法(hybird large eddy simulation/reynolds-averaged navier-stokes, Hybrid LES/RANS), 采用这种混合模拟方法结合5阶WENO格式对Ma=2.8平板湍流边界层进行了数值模拟, 并在计算区域上游...
We establish a character formula for admissible unitary representations of p-adic almost algebraic solvable groups and we deduce the Plancherel measure in the unimodular case.
Cette thèse traite des aspects géométriques et d’intégrabilité associés aux modèles de matrices aléatoires. Son but est de présenter diverses applications des modèles de matrices aléatoires allant d...
Let p and q be two distinct prime numbers, and Xpq/wq be the quotient of the Shimura curve of discriminant pq by the Atkin-Lehner involution wq. We describe a way to verify in wide generality a criter...
1.1. Les classes Xr+1,n(q). — On consid`ere un probl`eme de g´eom´etrie projective com- plexe, auquel nous ont conduits nos travaux r´ecents sur l’alg´ebrisation des tissus de...
The low flux infrared imaging needs performant high wavelength detectors. Quantum Well Infrared Photodetectors (QWIP), thanks to the maturity of GaAs, the possibility to adjust the detected wavelengt...
Parametric functions are currently used to represent droplet spectra in clouds and to develop bulk parameterizations of the microphysical processes and of their interactions with radiation. The most f...
The sensitivity of a stratocumulus-capped mixed layer to a change in cloud droplet concentration is evaluated with a large-eddy simulation (LES) and a mixed layer model (MLM). The strength of the seco...
