We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain ...
Suppression of displacement in severely slowed saccades
Saccadic suppression of displacement Slowed saccades
2015/7/31
Severely slowed saccades in Spinocerebellar ataxia have previously been shown to be at least partially closed-loop in nature,
their long duration means that they can be modified in-flight...
Evaluation of Geometrical Accuracy In Displacement Monitoring of Engineering Structures Using Close-range Photogrammetry
Close range Monitoring Non-metric
2015/7/15
Almost every part of the earth's surface and even man-made structures are subject to variations of size, shape and position with time.
The period of these changes differs from case to case depending ...
