We introduce CHAMP, an algorithm for online Bayesian changepoint detection in settings where it is difficult or undesirable to integrate over the parameters of candidate models. Rather than requiring integration of the parameters of candidate models as in several other Bayesian approaches, we require only the ability to fit model parameters to data segments. This approach greatly simplifies the...
Summary The Illumina Infinium HumanMethylationEPIC BeadChip is the new platform for high-throughput DNA methylation analysis, effectively doubling the coverage compared to the older 450 K array. Here we present a significantly updated and improved version of the Bioconductor package ChAMP, which can be used to analyze EPIC and 450k data. Many enhanced functionalities have been added, including ...
In this paper, Spherical Cap Harmonic Analysis (SCHA) method was applied to model the geomagnetic field over Vietnam and adjacent area between 15°S 25°N latitude 90°E 130°E in longitude by using magnetic data recorded on CHAMP Swarm satellites. The characteristic parameters of were set at maximum index Kint = 8 for internal fields, spherical cap half-angle θ0 20°. regional areas are modelled tw...
the grace mission has substantiated the low–low satellite-to-satellite tracking (ll-sst) concept. the ll-sst configuration can be combined with the previously realized high–low sst concept in the champ mission to provide a much higher accuracy. the line of sight (los) acceleration difference between the grace satellite pair is the most frequently used observable for mapping the global gravity f...
Cophasing six telescopes from the CHARA array, the CHARA-Michigan Phasetracker (CHAMP) and Michigan Infrared Combiner (MIRC) are pushing the frontiers of infrared long-baseline interferometric imaging in key scientific areas such as starand planet-formation. Here we review our concepts and recent improvements on the CHAMP and MIRC control interfaces, which establish the communication to the rea...
The MIDAS (Multi-Instrument Data Analysis System) algorithm performs a 4dimensional mathematical inversion. It is designed to assimilate a number of different measurement techniques, thus allowing the spatial and temporal factors to be accounted for in the inversion. In this study ionospheric data have been collected together from a number of observations in Europe. The MIDAS program incorporat...
