The spatial sign covariance matrix (SSCM), also known as the normalized sample (NSCM), has been widely used in signal processing a robust alternative to (SCM). It is well-known that SSCM does not provide consistent estimates of eigenvalues shape (normalized scatter matrix). To alleviate this problem, we propose BASIC (Bias Adjusted SIgn Covariance), which performs an approximate bias correction...

The objective of this study was to assess biothermal conditions in the selected Polish health resorts for specific forms climatic therapy. We calculated Universal Thermal Climate Index (UTCI) ten-year period (2008- 2017) and then added adjustment terms, taking into account changes metabolic rates during various physical activities from resting vigorous exercise. adjusted UTCI values increased w...
