EXTRACTION OF ICE SHEET LAYERS FROM TWO INTERSECTED RADAR ECHOGRAMS NEAR NEEM ICE CORE IN GREENLAND
Cryosphere Ice sheet layering Radar echo sounding Sub-glacial ice flow NASA IceBridge
2016/11/23
Accumulation of snow and ice over time result in ice sheet layers. These can be remotely sensed where there is a contrast in electromagnetic properties, which reflect variations of the ice density, ac...
Vectorising Bitmaps into Semi-Transparent Gradient Layers
Semi-Transparent Gradient Layers Vectorising Bitmaps
2016/5/24
We present an interactive approach for decompositing bitmap drawings and studio photographs into opaque and
semi-transparent vector layers. Semi-transparent layers are especially challenging to extra...

A NEW MEAN VELOCITY SCALING FOR TURBULENT BOUNDARY LAYERS
TURBULENT BOUNDARY LAYERS MEAN VELOCITY SCALING
2014/12/30
A new scaling, originally developed for the mean velocity
profile of turbulent pipe flow, was extended to the case of zero
pressure gradient turbulent boundary layers. At low Reynolds
numbers, the ...
