The measurement of volume pulse waves may be easily affected based on the measured position (different fingers or toes), body posture, as well as other factors. Therefore, interferences during measurement need to be removed. For this study, relevant parameters of volume pulse wave were obtained by changing the affecting factors. The data were analyzed in order to indicate the differences in vol...

In this paper, trend detection of wave parameters such as significant height, energy period, and power along the Italian seas was carried out. To purpose, time series in period 1979–2018 taken from global atmospheric reanalysis ERA-Interim by European Center for Medium-Range Weather Forecasts (ECMWF) were considered. Choosing a significance level equal to 90%, use Mann–Kendall test allowed esti...

In this paper, a 60-GHz millimeter-wave cluster channel model for various office environments was developed, and the impact of characteristics on wireless data transmission investigated. To develop model, double-directional measurement campaigns were conducted in university laboratory environment. A custom-developed sounder with an angular resolution 6° delay 2.5 ns at 58.32 GHz used mea...

Quasicircular binary black hole mergers are described by 15 parameters, of which gravitational wave observations can typically constrain only $\ensuremath{\sim}10$ independent combinations to varying degree. In this work, we devise coordinates that remove correlations, and disentangle well- poorly-measured quantities. Additionally, identify approximate discrete symmetries in the posterior as pr...

Total electron content measurements by using dual-frequency signals of global navigation satellite systems (GNSS) makes it possible to obtain the distribution density ionosphere with high spatial and temporal resolution. Such resolution allows explore small-scale traveling ionospheric disturbances generated terrestrial geophysical events, including seismic activity, solar terminator passage, at...
