Experimental study on permeability of phyllite talus in Whenchuan-Maerkang expressway considering fragment orientation

open access: yesYantu gongcheng xuebao, 2023
The phyllite talus is widely distributed along the Wenchuan-Maerkang expressway. Considering that the phyllite has obvious flat geometric characteristics, most of its spatial distribution in the talus has a certain degree of directionality, so that the ...

The effects of angle-arm length on judgments of angle magnitude and orientation contrast [PDF]

open access: yesPerception & Psychophysics, 1984
Acute angles frequently are overestimated, an effect that has been attributed to lateral inhibitory mechanisms. It can be derived from such theories that lengthening the arms of an angle should either reduce or not affect its judged subtense. However, in Experiments 1 and 2, it was found that angles with longer arms were judged larger. In Experiment 3,
