Perceptual grouping leads to objecthood effects in the Ebbinghaus illusion

Michael Herzog, Aline Françoise Cretenoud, Einat Rashal

The Ebbinghaus illusion is argued to be a product of low-level contour interactions or a higher cognitive comparison process. We examined the effect of grouping on the illusion by manipulating objecthood, i.e., the degree to which an object is a cohesive p ...

Uncontrolled manifold analysis of the effects of a perturbation-based training on the organization of leg joint variance in cerebellar ataxia

Silvestro Micera

Walking patterns of persons affected by cerebellar ataxia (CA) are characterized by wide stride-to-stride variability ascribable to: the background pathology-related sensory-motor noise; the motor redundancy, i.e., an excess of elemental degrees of freedom ...

The performance of collars on scour reduction at tandem piers aligned with different skew angles

Anton Schleiss, Giovanni De Cesare, Sargol Memar

Local scouring is a leading cause of bridge collapses. To protect bridges against local scouring, different countermeasures have been proposed and tested in the literature. In this study, the performance of collars was evaluated for scour reduction at two ...

Investigation of local scour around tandem piers for different skew-angles

Anton Schleiss, Giovanni De Cesare, Sargol Memar

In the present study the effect of the skew-angle of the alignment of tandem piers on local scour depth around them is investigated. The tandem piers were aligned with different skew-angles of 𝜃𝜃 = 0°, 30°, 45°, 60°, 90° with respect to the flow direction. ...

Optical prism for creating multiple views of an image

Theo Lasser, Marcel Leutenegger, Stefan Geissbuehler

Optical prism comprising two external parallel and reflecting surfaces, one internal interface, parallel to said surfaces and acting as light splitter; said prism furthermore comprising an entrance side forming an angle β with respect to said interface and ...

Seam Carving for Text Line Extraction on Color and Grayscale Historical Manuscripts

Sabine Süsstrunk, Nikolaos Arvanitopoulos Darginis

We propose a novel algorithm for automatic text line extraction on color and grayscale manuscript pages without prior binarization. Our algorithm is based on seam carving to compute separating seams between text lines. Seam carving is likely to produce ...

A new approach to accurate measurement of uniaxial joint angles based on a combination of accelerometers and gyroscopes

Kamiar Aminian, Hooman Dejnabadi

A new method of measuring joint angle using a combination of accelerometers and gyroscopes is presented. The method proposes a minimal sensor configuration with one sensor module mounted on each segment. The model is based on estimating the acceleration of ...

12C(n, n), (n, n') and (n, n') 3a reactions at 14.1 MeV

The 12C(n, n), (n, n') and (n, n') 3 α reactions have been studied at 14.1 MeV by a time-of-flight method, with a scintillating scatterer. The angular distributions and integrated cross sections were obtained for the following channels: Q = 0 (0+) and -4.4 ...
