Visual Duration but Not Numerosity Is Distorted While Running

There is increasing evidence that action and perception interact in the processing of magnitudes such as duration and numerosity. Sustained physical exercise (such as running or cycling) increases the apparent duration of visual stimuli presented during the activity. However, the effect of exercise on numerosity perception has not yet been investigated. Here, we asked participants to make either a temporal or a numerical judgment by comparing the duration or numerosity of standard stimuli displayed at rest with those presented while running. The results support previous reports in showing that physical activity significantly expands perceived duration; however, it had no effect on perceived numerosity. Furthermore, the distortions of the perceived durations vanished soon after the running session, making it unlikely that physiological factors such as heart rate underlie the temporal distortion. Taken together, these results suggest a domain-selective influence of the motor system on the perception of time, rather than a general effect on magnitude.

Pollution Severity Diagnose on Solid Insulators using the Partial Discharge and Flashover Characteristics

In this paper deals with the investigation of partial discharge and flashover characteristics of the ceramic and non-ceramic insulators in order to succeed a best diagnostic tool to determine the pollution severity of exterior insulators. In this experiment, laboratory based tests are achieve on the ceramic and non-ceramic insulators under AC voltage at various pollution levels manipulate the sodium chloride (NaCl) a as contaminant. Initially the test are conducted by the pure and contaminated at sample of insulators. In supplement, Partial discharge (PD) occurs on the contaminated surface of the sample insulator is to be measured and to investigate the PD wave form. The PD detection is sufficient to analyze maintenance of insulators of the transmission line. To evaluate the statistical analysis of PD patterns in order to accomplish a numerical judgment of pollution severity of the ceramic and non-ceramic insulators. In consequence, ceramic and non-ceramic insulator exhibit the pollution severity of the exterior insulators should be recognized from the partial discharge patterns investigation.
