In this paper, implementation of an extended form of a no-slip wall boundary condition is presented for the three-dimensional (3-D) lattice Boltzmann method (LBM) for solving the incompressible fluid flows with complex geometries. The boundary condition is based on the off-lattice scheme with a polynomial interpolation which is used to reconstruct the curved or irregular wall boundary on the ne...

Techniques for spherical osteotomy, such as rotational acetabular osteotomy, can help orthopaedic surgeons correct bony deformities and remove spherical acetabular components. Curved chisels are used during a spherical osteotomy, but they require skill and have a potential risk of damaging blood vessels or nerves. In order to perform a precise, quick and safe spherical osteotomy, we have develo...

in river meandering, when flow passes through a bend, reduction of flow velocity and rising hydrostatic pressure cause super elevation phenomena at outer side and reduction of water surface at inner-side of the bend. a helical motion results, causing erosion of the outer side of the bend. installation of submerged vanes on the stream bed can reduce erosion of the outer bank significantly. in th...

Temporal-integration functions and psychometric functions for detection were obtained in eight users of the Nucleus 22-electrode cochlear implant. Stimuli were 100-Hz, 200-microseconds/phase trains of biphasic pulses with durations ranging from 0.44 to 630.4 ms (1 to 64 pulses). Temporal-integration functions were measured for 21 electrodes. Slopes of these functions were considerably shallower...

Many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. On sloping basins, however, few such studies have been performed so that the issue requires more investigation. A significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. This study was carried ...

Determining the significance of slope differences is a common requirement in studies of self-thinning, ontogeny and sexual dimorphism, among others. This has long been carried out testing for the overlap of the bootstrapped 95% confidence intervals of the slopes. However, the numerical random re-sampling with repetition favours the occurrence of re-combinations yielding largely diverging slopes...

We demonstrate experimentally the x-ray lithography techniques to fabricate micro structures on curved surfaces such as convex and cylinder surfaces. In order to realize fabricate micro structures on curved surface, two x-ray lithography methods are described. One method is double x-ray exposures method with moving resist stage, the other is flexible mask on curved surface with rotating the res...

We describe an algorithm for computing boundary slopes of 2-bridge links. As an example, we work out the slopes of the links obtained by 1/k surgery on one component of the Borromean rings. A table of all boundary slopes of all 2-bridge links with 10 or less crossings is also included.

We consider drawings of graphs in the plane in which edges are represented by polygonal paths with at most one bend and the number of different slopes used by all segments of these paths is small. We prove that d 2 e edge slopes suffice for outerplanar drawings of outerplanar graphs with maximum degree ∆ > 3. This matches the obvious lower bound. We also show that d 2 e + 1 edge slopes suffice ...
