The CFD simulation has been undertaken concerning natural convection heat transfer of a nanofluid in vertical square enclosure, whose dimension, width height length (mm), is 40 40 90, respectively. The nanofluid used in the present study is -water with various volumetric fractions of the alumina nanoparticles ranging from 0-3%. The Rayleigh number is . Fluent v6.3 is used to simulate nanofluid ...

A numerical simulation is conducted to investigate movement of iron ore fines by ship's rolling motion under saturated condition using the microscopic fluid coupling scheme devised in Discrete Element Method. The solves pore water pressure particle assemblies change void spaces and flows between them. Updated applied related particles around spaces. result shows liquefaction, that is, increases...

W e present a n algorithm for extracting and classifying two-dimensional motion in a n image sequence based o n mot ion trajectories. First, a multiscale segmentation is performed to generate homogeneous regions in each frame. Regions between consecutive frames are then matched to obtain 2-view correspondences. A f i n e transformations are computed f rom each pair of corresponding regions to d...

Prototypes have been designed and manufactured for a lightweight portable device which continually moves all the joints of the hand passively through a range of motion. Inflatable bag modules in the palm of the hand are ganged together to create the required range of motion. A battery-operated air pump cycles compressed air to the modules. Initial clinical experience with patients who have flex...

We found that a hand posture with the palms together located just below the stream/bounce display could increase the proportion of bouncing perception. This effect, called the hands-induced bounce (HIB) effect, did not occur in the hands-cross condition or in the one-hand condition. By using rubber hands or covering the participants' hands with a cloth, we demonstrated that the visual informati...
