The detection of the primordial B-mode spectrum of the polarized cosmic microwave background (CMB) signal may provide a probe of inflation. However, observation of such a faint signal requires excellent control of systematic errors. Interferometry proves to be a promising approach for overcoming such a challenge. In this paper we present a complete simulation pipeline of interferometric observa...

Keywords: geometric matching, aircraft tracks, systematic errors of radars A problem of processing the measurements from air surveillance radars is considered. The measurements are provided by observation of air traffic. This processing aims at matching the tracks of aircrafts obtained by various radars and estimation of their systematic errors. The error estimates are built in the form of a " ...

Although individual observational groups vigorously test their data sets for systematic errors, the pre-WMAP CMB observational data set has not yet been collectively tested. Under the assumption that the concordance model is the correct model, we have explored residuals of the observational data with respect to this model to see if any patterns emerge that can be identified with systematic erro...

Large knowledge bases, such as DBpedia, are most often created heuristically due to scalability issues. In the building process, both random as well as systematic errors may occur. In this paper, we focus on finding systematic errors, or anti-patterns, in DBpedia. We show that by aligning the DBpedia ontology to the foundational ontology DOLCEZero, and by combining reasoning and clustering of t...
