Our proposal incorporates a large number of parameters, such as body temperature, heart rate (HR), heart rate variability (HRV), oxygen saturation, the pressure exerted by feet, sweat and the level of activity. Low-cost sensors were considered for our proposal to be available to a large ...
and arrhythmic events that can be measured with these recordings are the RR interval changes between consecutive beats and after spontaneous ventricular premature complexes, which can be used for the analysis of the heart rate variability (HRV) and the heart rate turbulence (HRT), respectively [3...
The basic compositions of PSAs and HMPSAs consist of physical blends of polymer and low molecular weight resin (also named as tackifier), although small amounts (less than 10 wt%) of additives such as oils, plasticizers, stabilizers, or fillers can also be added. The thermal, surface, ...

Introduction Low-specific-speed centrifugal pumps have the characteristics of small flow rate, large head, and low efficiency, which are widely used in aerospace, military industry, electric power, water conservancy, chemical industry, and other important fields. After decades of efforts, with the ...
