Characterization of Machined Surface Topography Based on the Normal Declination Angle of Microfacets

open access: yesMicromachines, 2021
It is important to characterize surface topography in order to study machined surface characteristics. Due to the features of periodicity and randomness of machined surface topography, the existing topographical parameters may not describe its features ...

Do Explicit Estimates of Angular Declination Become Ungrounded in the Presence of a Ground Plane?

open access: yesI-Perception, 2018
In a series of seven experiments (total N  = 220), it is shown that explicit angular declination judgments are influenced by the presence of a ground plane in the background. This is of theoretical importance because it bears on the interpretation of the

Design and research of single‐sided slotted waveguide antenna with a large beam declination

open access: yesIET Microwaves, Antennas & Propagation, 2021
The slot of the conventional longitudinal slot antenna is alternately opened on both sides of the broadside. A novel single‐sided slot array with a large‐declination (biased towards the load) is proposed, in which the slots are only biased to the same ...

Perceptual Scale Expansion: An Efficient Angular Coding Strategy For Locomotor Space [PDF]

open access: yes, 2011
Whereas most sensory information is coded on a logarithmic scale, linear expansion of a limited range may provide a more efficient coding for the angular variables important to precise motor control.
