Rolling perception without rolling motion.
The texture of a rolling circle depicts the translational and rotational components of its motion. In the case of a homogeneous circle, however, visual cues to the rotational component of motion are absent. To examine how the visual system resolves undetermined motion cues, optically neutral circles were displaced so that changes in their orientation were invisible. Contextual cues systematical...

متن کاملRolling friction and bistability of rolling motion
The rolling motion of a rigid cylinder on an inclined flat viscous surface is investigated and the nonlinear resistance force against rolling, FR(v), is derived. For small velocities FR(v) increases with velocity due to increasing deformation rate of the surface material. For larger velocity it decreases with velocity due to decreasing contact area between the rolling cylinder and the deformed ...
متن کاملCylinder Rolling on Another Rolling Cylinder
This problem was suggested by Bradley Klee. For the related case of one cylinder rolling inside another, see [1]. When one cylinder is directly above the other, we define the line of contact of the lower cylinder, 1, with the horizontal plane to be the z-axis, at x = y = 0. Then, the condition of rolling without slipping for the lower cylinder is that when it has rolled (positive) distance x1, ...
متن کاملThe State of SLIT
As was noted in last month’s editorial, significant progress has been made in the past year in many aspects of Allergy and Immunology worldwide, especially in areas that are spearheaded by WAO. One of the critical aspects of our discipline is the use of allergen specific immunotherapy as treatment for allergic diseases. Originally, the empiric institution of this therapy was found to have profo...
