Parameter estimation of superdiffusive motion of energetic particles upstream of heliospheric shocks

, 2015
In-situ spacecraft observations recently suggested that the transport of energetic particles accelerated at heliospheric shocks can be anomalous, i.e. the mean square displacement can grow non-linearly in time. In particular, a new analysis technique has

Local correlation-based transition model for aerodynamic flows in wide speed range

Engineering Applications of Computational Fluid Mechanics
A local correlation-based transition model is developed for aerodynamic flows in a wide speed range. New localized methods for the momentum-thickness Reynolds number are introduced for constructing local transition indicators. New transition correlations

Time-dependent Hamiltonian estimation for Doppler velocimetry of trapped ions

, 2015
The time evolution of a closed quantum system is connected to its Hamiltonian through Schroedinger's equation. The ability to estimate the Hamiltonian is critical to our understanding of quantum systems, and allows optimization of control.

Simulation of the 2010 September 9 Solar Energetic Particle Event by Using a Data-constrained Transport Model

The Astrophysical Journal
Solar energetic particles (SEPs) can cause damage to spacecraft systems and affect human activities in space. On 2010 September 9, a gradual SEP event was observed by spacecraft STEREO-A, Solar and Heliospheric Observatory (SOHO), and STEREO-B at widely ...

Thermal Radiation Transport with Tensor Trains

The Astrophysical Journal
We present a novel tensor network algorithm to solve the time-dependent, gray thermal radiation transport equation. The method invokes a tensor train (TT) decomposition for the specific intensity.

MODELING OF ROUGH WALL BOUNDARY LAYERS WITH AN INTERMITTENCY TRANSPORT MODEL

TASK Quarterly, 2010
The paper presents a new extension of the γ-Reθt model to account for both the laminar-turbulent transition and the surface roughness. The new modeling approach takes into account the pressure gradient, turbulence intensity and roughness height and ...
