In this paper we present a new type of profiling analysis called Variational Path Profiling (VPP). ...
We present a profiling and analysis approach to find these variational paths, so that they can be communicated back to a programmer to guide optimization. ...
Variational Path Profiling In this section we describe the sampling approach used to gather the variational path profiles. ...

Three models for nonuniform reflectivity variation along the precipitation path are studied. ...
It is shown that the estimate of specific differential phase over a nonuniform rainfall path is biased, and the bias increases with increased reflectivity variation along the path. ...
However, the bias is independent of the sign of the reflectivity variations because of symmetry of K DP and ⌽ DP profiles about the uniform path model profile. ...

The statistics of RMS delay spread and the received power in the multipath profiles are computed and compared for these experimental variations. ...
The database is divided into two classes: spatial and short time variations. ...
This is because there are usually more paths in an OLOS than in an LOS profile and hence fluctuations also occur in more paths in an OLOS profile. ...

This variation may result from known structural differences among nerve fiber bundles that serve different retinal regions. Constant ⌬n along bundles is consistent with this hypothesis. ...
⌬n profiles on circles of different diameter were similar, suggesting that ⌬n did not vary along nerve fiber bundles. CONCLUSIONS. RNFL birefringence varies with position around the ONH. ...
To show the variation in the SLP measurement alone, one OCT scan path was used to extract an R profile from each of the three SLP images. ...
