Humans can recover the structure of a three-dimensional object from motion cues alone. Recovery of structure-from-motion (SFM) from the projected 2D motion field of a rotating object has been studied almost exclusively in the condition where the axis of rotation lies in the frontoparallel plane. Here we assess the ability of humans to recover SFM in the general case, where the axis of rotation ...

Understanding the contact mechanics of rough tooth surfaces is critical in order to understand phenomena such as surface flash temperature, wear, and gear vibration. In this paper, behavior between meshing beveloid pairs with elliptical asperities focus. The area distribution function asperity was proposed for point curved by transforming elastic problem into an arbitrary radius curvature. addi...

  This study aimed to design a bycatch reduction device (BRD) for shrimp beam trawl, which is manufactured by flexible materials to reduce bycatch for the gear in the South Sea of Korea. The model test was carried out to understand the shape of the gear in the water and to measure the variation of flow speed due to the BRD in a circulating water channel. Catches were compared between a shrimp b...

Tooth root crack is considered as one of the crucial causes of failure in the gearing system and it occurs at the tooth root due to an excessive bending stress developed in the root region. The modern power transmission gear drives demand high bending load capacity, increased contact load capacity, low weight, reduced noise and longer life. These subsequent conditions are satisfied by the aid o...

Guang-Hong Chen University of Wisconsin–Madison Department of Medical Physics Madison, Wisconsin 53704 and University of Wisconsin–Madison Department of Radiology Madison, Wisconsin 53792 E-mail: [email protected] Abstract. We present a cone-beam image reconstruction algorithm for helical CT scanning with a tilted gantry and N-PI data acquisition. When the gantry is tilted, the effective source t...
