Large eddy simulation of buoyant plumes [PDF]

, 2003
A 3d parallel CFD code is written to investigate the characteristics of and differences between Large Eddy Simulation (LES) models in the context of simulating a thermal buoyant plume. An efficient multigrid scheme is incorporated to solve the Poisson

Kalman Filter and Its Application in Data Assimilation

Atmosphere, 2023
In 1960, R.E. Kalman published his famous paper describing a recursive solution, the Kalman filter, to the discrete-data linear filtering problem.

Fast simulation of large‐scale growth models [PDF]

Random Structures & Algorithms, 2011
AbstractWe give an algorithm that computes the final state of certain growth models without computing all intermediate states. Our technique is based on a “least action principle” which characterizes the odometer function of the growth process. Starting from an approximation for the odometer, we successively correct under‐ and overestimates and ...

Holocene temperature response to external forcing: assessing the linear response and its spatial and temporal dependence [PDF]

Climate of the Past, 2019
Previous studies show that the evolution of global mean temperature forced by the total forcing is almost the same as the sum of individual orbital, ice sheet, greenhouse gas and meltwater single forcing runs in the last 12 000 years in three ...

Large scale traffic simulations [PDF]

, 1997
Large scale microscopic (i.e. vehicle-based) traffic simulations pose high demands on computational speed in at least two application areas: (i) real-time traffic forecasting, and (ii) long-term planning applications (where repeated {open_quotes}looping{close_quotes} between the microsimulation and the simulated planning of individual person`s behavior

Large scale multiagent simulation on the grid [PDF]

CCGrid 2005. IEEE International Symposium on Cluster Computing and the Grid, 2005., 2005
Simulating large scale, distributed systems of autonomous decision-makers, e.g. global logistics supply networks, is a huge challenge for hardware and software infrastructure as well as managing the process of simulation. Facing this challenge, we are going to introduce an architecture for large scale grid-based simulation infrastructure to enable high

Advances and visions in large-scale hydrological modelling : findings from the 11th Workshop on Large-Scale Hydrological Modelling [PDF]

, 2008
Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the German-speaking community for discussing recent ...

Comparison of Subgrid-scale Viscosity Models and Selective Filtering Strategy for Large-eddy Simulations [PDF]

, 2013
Explicitly filtered large-eddy simulations (LES), combining high-accuracy schemes with the use of a selective filtering without adding an explicit subgrid-scales (SGS) model, are carried out for the Taylor-Green-vortex and the supersonic-boundary-layer ...

Investigating tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯

European Physical Journal C: Particles and Fields, 2019
In the framework of the quark delocalization color screening model, we investigate tetraquarks composed of $$us\bar{d}\bar{b}$$ usd¯b¯ and $$ud\bar{s}\bar{b}$$ uds¯b¯ in two structures: meson-meson structure and diquark–antidiquark structure.
