Nowadays, data reduction is becoming increasingly important in dealing with the large amounts of scientific data. Existing multilevel compression algorithms offer a promising way to manage at scale, but may suffer from relatively low performance and quality. In this paper, we propose MGARD+, refactoring framework drawing on previous methods, achieve high-performance decomposition high-quality e...

In recent times, ultra-wideband (UWB)-based positioning systems have become popular in sport performance monitoring. UWB system uses time of arrival to calculate the range data between devices (i.e. anchors, tags), and then use trilateration algorithms estimate position coordinates. practical applications, non-line-of-sight transmissions multipath propagations lead inaccurate lower accuracy. Th...
