Crowdsourced demarcations of object boundaries in images (segmentations) are important for many vision-based applications. A commonly reported challenge is that a large percentage of crowd results are discarded due to concerns about quality. We conducted three studies to examine (1) how does the quality of crowdsourced segmentations differ for familiar everyday images versus unfamiliar biomedic...

The application of the frequency detector method for measuring phase noise spectrum semiconductor lasers has been experimentally demonstrated. is based on an unbalanced Mach-Zehnder interferometer and a photodetector. Analytical relations are obtained that allow one to choose parameters perform experimental calibration system. A technique proposed spectral components in presence slow drift dela...

In the Cochrane Database of Systematic Reviews (CDSR) 75% reported meta-analyses contain five or fewer studies. For a small dataset reasonable goodness-of-fit test on statistical model cannot be performed since either it requires large sample size for validity asymptotic approximation might not powerful enough to detect deviation from target model. Random effects under assumption normality is c...
