Do the mechanisms that underlie the perception of translational and rotational object motion show evidence of independent processing? By probing the perceived speed of translating and/or rotating objects, we find that an object's form contributes in independent ways to the processing of translational and rotational motion: In the context of translational motion, it has been shown that the more ...

Devices for the rotational culture of cells and the study of biological reactions have been widely applied in tissue engineering. However, there are few reports exploring the effects of rotational culture on cell morphology, nitric oxide (NO) production, and cell cycle of the endothelial cells from human umbilical vein on the stent surface. This study focuses on these parameters after the cells...

A new type of micro-joint based on an elastic design concept is proposed for large rotational movement. The proposed new 3D micro-joint was designed based on a cross-spring that has precise and reliable motion. However, the cross-spring has a limitation in the range of rotational angle. To improve the range of rotational movement, the proposed 3D micro-joint was modified with a helical structur...

In this article, turbulent flow heat transfer in the air gap between rotor and stator of a generator under nonhomogeneous heat flux is studied experimentally. The rotor consists of four symmetrical triangular grooves. The stator surface is smooth and does not include any grooves. The relative heat flux between the rotor and the stator is 1 to 3. Temperature and heat flux are measured locally at...

Because the force required to rotate a body about an axis is directly proportional to its rotational inertia about the axis, it is likely that animals with high rotational inertia would be constrained in their turning abilities. Given that rotational inertia scales with mass(1.67) in geometrically similar animals, whereas the ability to apply torque scales with mass(1.00), larger animals would ...

In fractured rock masses, discontinuities control the mechanical response of slopes. They even define geometry a potential failure, known kinematically controlled failure. Hence, proper characterization and description are needed to assess their stability. Accordingly, in this work, reliability assessment wedges' stability was performed by Monte Carlo simulation. The orientation modeled as rand...
