In the visual cortex of the monkey the horizontal organization of the preferred orientations of orientation-selective cells follows two opposing rules: 1) neighbors tend to have similar orientation preferences, and 2) many different orientations are observed in a local region. Several orientation models which satisfy these constraints are found to differ in the spacing and the topological index...

In this article a distinction between a pragmatic and a critical orientation of action research is made. These orientations can be considered, implicitly or explicitly, to be the main alternatives in AR today. What are the assumptions behind, and practical implications for, AR projects with different orientations? A number of themes are introduced where a tension between the two are identified ...

Abstract The quality of the components fabricated using fusion deposition modelling (FDM) can be tailored by proper selection process parameters values. Print orientation is a key parameter in FDM which has strong influence on defect formation and thereby mechanical properties components. To address print orientation, Polyethylene terephthalate glycol (PETG) samples were tested. different orien...

BACKGROUND AND PURPOSE Left-sided breast cancer patients pose a difficult clinical challenge when significant heart and contralateral breast irradiation are present, particularly with tangential uniform beams. The aims of the study are: (1) to design and evaluate a simplified intensity-modulated radiotherapy (IMRT) (SI) solution using pre-defined segments, (2) to compare the SI technique with a...

We examined how much depth we perceive when viewing a depiction of a slanted plane in which binocular disparity and monocular perspective provide different slant information. We exposed observers to a grid stimulus in which the monocular--and binocular-specified grid orientations were varied independently across stimulus presentations. The grids were slanted about the vertical axis and observer...
