A C2 Polar Jet Subdivision [article]

K. Karciauskas, A. Myles, J. Peters
2006 Symposium on geometry processing : [proceedings]. Symposium on Geometry Processing  
Each vector defines partial derivatives, referred to as jets in the following and subdivision computes new jets from old jets. By default, the jets are automatically initialized from a design mesh.  ...  We describe a subdivision scheme that acts on control nodes that each carry a vector of values.  ...  Polar jet subdivision is inspired by this approach but uses local jets in place of an explicit guide surface.  ...

1997 Monthly notices of the Royal Astronomical Society  
Using a simple lens model, we show that the image configuration is consistent with lensing by a galaxy, represented by a potential with a small ellipticity.  ...  By matching radio spectra and polarization properties, we identify which components are likely to be gravitational images of the same part of the source.  ...  For part of this work, UK was supported by a PP ARC/SERC PhD studentship. UK is very grateful to the Astrophysics Department, Oxford University, for hospitality.  ...

No evidence of a signal is seen. A lower limit on the mass of the Standard Model Higgs boson of 107.7 GeV/c2 at 95% confidence level is set.  ...  In the MSSM, lower limits of 91.2 and 91.6 GeV/c2 are derived for the masses of the neutral Higgs bosons h and A, respectively.  ...  Analyses Signal The three-branch subdivision in the NN stream four-jet final state was replaced by a simpler and similarly sensitive two-branch treatment: the first branch (4b) containing the events selected  ...

Heavy Cold-Season Precipitation in the Northwestern United States: Synoptic Climatology and an Analysis of the Flood of 17–18 January 1986

1999 Weather and forecasting  
There is also a smaller contribution from a stationary anticyclone over the southwestern United States.  ...  The first objective is accomplished through a 46-case composite spanning the years 1962-88; the second objective is addressed through diagnosis of a flooding event that occurred on 17-18 January 1986.  ...  This feature suggests a southward shift of the polar front jet stream over the Pacific relative to its climatological position.  ...
