Grid-Free Simulation of the Spatially Growing Turbulent Mixing Layer
Grid-Free Simulation Spatially Growing Turbulent Mixing Layer
2016/5/18
The spatially developing, unforced, turbulent mixing layer is simulated via a grid-free vortex method. Vortex filaments composed of straight tubes are used as the computational element with new vortex...
AN IMPROVED ENDMEMBER EXTRACTION ALGORITHM BY INVERSING LINEAR MIXING MODEL
Hyperspectral Remote Sensing Spectral Indices Image Understanding Simulation Extrapolation
2015/12/31
In hyperspectral imagery there are some cases when no pure pixels present due to the limitation of the sensors' space resolution and the complexity of the ground components, and then the endmembers ex...

Linear mixing spectral correction laboratory measurements hyperspectral imaging
2016/1/15
In order to understand the characteristics of the data collected by hyperspectral imaging systems, it is important to discuss the physics behind the scene radiance field incident on the imaging system...
The fastest mixing Markov process on a graph and a connection to a maximum variance unfolding problem
Markov process fast mixing second smallest eigenvalue semidefinite programming dimensionality reduction
2015/8/10
We consider a Markov process on a connected graph, with edges labeled with transition rates between the adjacent vertices. The distribution of the Markov process converges to the uniform distribution ...
The Role of Small-Scale Topography in Turbulent Mixing of the Global Ocean
Turbulent Mixing Global Ocean
2015/7/29
Maintenance of the observed basin-scale thermohaline (temperature T and salinity S) structure of the world's oceans appears to require mixing to provide dense abyssal waters, which are formed at high ...

Simulated Biomass Bed Reactor a Center Feeding Tube
2014/10/23
Producing gasoline-type fuels from lignocellulosic biomass has two advantages over producing alcohol-type fuels from plant sugars: gasoline has superior fuel characteristics and plant lignin/cellulose...
Analysis of Occupational Accidents by Mixing and Crushing Machines
Analysis of Occupational Accidents Mixing Crushing Machines
2013/9/30
Every year, there are about 10 fatal occupational accidents, and about 250 accidents involving at least 4 days of lost work time, that involved mixing and crushing machines. However, the degrees to wh...
THz-Wave Generation from GaP THz Photonic Crystal Waveguides under Difference-Frequency Mixing
THz-Wave Generation Photonic Crystal Waveguide Nonlinear Optical Effect
2013/1/30
GaP terahertz (THz) two-dimensional (2D) photonic crystal (PC) waveguides with line defects were fabricated using inductively-coupled plasma reactive-ion etching (ICP-RIE) in Ar/Cl2 gas chemistries. T...
This work investigates the effect of phase fluctuation averaging on phase fluctuation induced by intrachannel four-wave mixing (IFWM) in highly dispersed differential phase-shift keying transmission s...
Mixing in viscous fluids is challenging, but chaotic advection in principle allows ecient mixing. In the best possible scenario, the decay rate of the concentration pro le of a passive scalar should ...
The platinum nuclei: concealed configuration mixing and shape coexistence
