The calculation method of the Arithmetic Mean Deviation (Ra) is presented for rotational turning. necessary equations Ra are given beginning from equation cut surface theoretical profile, and we determine values in studied range technological parameters. Cutting experiments with these data were performed roughness machined surfaces measured. Then carried out a comparative analysis measured calc...

Abstract At present, it has become very convenient to collect channel state information (CSI) from ubiquitous commercial WiFi network cards, and the location or activity of a human who affects CSI can be recognized by analyzing change CSI. Therefore, wireless sensing technology based on received widespread attention. However, existing CSI-based gesture recognition methods still have some proble...

The Shewhart X¯- and S-charts are most commonly used for monitoring the process mean variability based on assumption of normality. However, many distributions may follow a positively skewed distribution, such as lognormal distribution. In this study, we discuss construction three combined jointly standard deviation. simulation results show that more effective when distribution is skewed. A real...

convolution each of the BOLD responses with a single universal transfer function, modeled BOLD signals were generated which when differenced with the measured BOLD signals showed residual signals which were smaller than the measurement uncertainty. The root mean square (RMS) of the residual signal (left number) was compared with the averaged standard deviation (SD) of the measured data (right n...
