This allowed a faster and more accurate computation of likelihood models within our BEAST analyses.
This system was supplemented by a range and range-rate system which was expected to permit the more accurate computation of the orbit parameters in a shorter time, especially in the case of the highly eccentric orbit in which the satellite spent a large fraction of its time at large distances from the Earth where the angular rates are very low.
More accurate computation results can be obtained using 3D algorithms.
In addition, for more accurate computation and stable level set evolution, we need to regularize the level set function by penalizing its deviation from a signed distance function [13, 28], which can be characterized by the following energy functional P ϕ = ∫ Ω 1 2 ∇ ϕ x − 1 2 d x (21).
For this second case, since the numerical methods and physical models used in the present work have been noticeably improved compared to the original publication (finer grid, higher level of convergence, more accurate computation of the activity coefficient…), considerable differences in the findings are observed.
This is expected, as having more PRDs in the training set allows for more accurate computation of covariation scores and the construction of more informative prediction models.
More accurate computation can be done using FastRT web page which takes into consideration, the latitude, dietary consumption of vitamin D, duration and time of exposure, etc. Clouds aerosols, thick ozone events, can reduce the vitamin D synthesis and force a "vitamin D winter" even near the equator.
For more accurate computation, we defined the initial number of dusts 10,000, the max power distance of center dust 5, and the epochs 1,000, which was the same as used in GA and SA (for more information of detail parameters, please see description of GFA).
We kept these values constant to simplify computation; a more accurate approach would be to account for the brief shock these activities give to indoor PM2.5 levels stochastically.
