This contribution addresses the critical question of sampling rates used to measure variables of interest by cyberphysical and environmental monitoring systems. The data used in this analysis were measured and recorded in a Brazilian forest canopy between 2007 and 2014. Through variogram analysis time series of air temperature, humidity, soil moisture and photosynthetically active radiation, this...
This paper analyzed the relationship between atmospheric temperature and blood pressure, and found out the correlation coefficients atmospheric temperature affect on blood pressure. It used Matlab as a tool and adopt cosine vector angle to quantitative analysis, and adopt FFT (fast Fourier transform algorithm) transform to frequency spectrum space to qualitative analysis. It has account the correlation...
