A C2 Polar Jet Subdivision
[article]
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. ...

Multifrequency radio observations of the gravitational lens system 1938 + 666
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. ...

Searches for neutral Higgs bosons in e+e− collisions at centre-of-mass energies from 192 to 202 GeV
2001
Physics Letters B
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 ...

Atmospheric Chemistry and Physics Discussions
<br><br> In this work, a classification system (Identification and Classification of Cirrus or IC-CIR) is introduced to identify cirrus clouds by their formation mechanisms. ...
Through a comparison to convection-permitting model simulations and back-trajectory based analysis, it is shown that the regimes can provide extra information on the properties and origin of cirrus that ...

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. ...

Saturn from Cassini-Huygens
The silicate fraction inferred from its density of 1:68 g cm 2 is probably differentiated into a core, though we have not direct evidence for differentiation. ...
Above the core there is probably a global or regional liquid water layer, inferred from several models of tidal heating, and an ice shell thick enough to support the 1 km amplitude topography seen on Enceladus ...
