On Modeling Profiles instead of Values
[article]
2012
arXiv
pre-print
Instead of maximum likelihood, which maximizes the probability of the ob served values, we propose a different estimate, the high-profile distribution, which maximizes the probability of the observed profile ...
, the high-profile and maximum-likelihood distributions are roughly the same, but when the number of symbols is large, the distributions differ, and high-profile better explains the data. ...
It is based on the simple premise that the underlying distribution should be estimated based not on the specific values observed, but only on the number of values appearing any given number of times. ...

These 3 restrictions above, can be combined in the following one: all profiles that have a maximum value of contrast less than 0.1 have been processed; we have taken a maximum value of 0.1 instead of zero ...

However, since one of our conclusions (which remains unchanged) is that UC models are marginally inferior to CF and IN ones, we report these numbers only for completeness. ...
For Figure 11 , the caption should read τ = 0.12 (instead of τ = 2). For Figure 18 , the caption should read τ = 0.12 and 0.37 for the IN and UC models, respectively (instead of τ = 2). ...

Single and joint statistics of ducting layer parameters determined from vertical profiles of atmospheric refractivity
2011
2011 XXXth URSI General Assembly and Scientific Symposium
Vertical profiles of atmospheric refractivity measured on 150 m mast are fitted with a modified Webster duct model. Time series of duct model parameters are obtained with one minute resolution. ...
Empirical single and joint statistics of duct model parameters are determined from 7 month data. Interrelations between the duct parameters are discussed. ...
Instead, it should be taken as simply one parameter of (1) that in combination with the other four parameters models a particular vertical profile. ...

Profile shape parameterization of JET electron temperature and density profiles

The temperature and density profiles of the Joint European Torus are parameterized using log-additive models in the control variables. ...
The L-mode normalized density shape depends primarily on the ratio of line average density, n̅, to the edge safety factor, q_95. As n̅/q_95 increases, the profile shape broadens. ...
If the effective charge is added, the PAR value is .0632, while using the line average density instead of Z ef f yields a worse value of .0640. ...
