In this paper, by combining with the network structures of the twisted n cube and the crossed cube, the counterchanged crossed cube network is proposed, a rigorous recursive definition is made, and the network topology structure graph is offered. Basing on the definition of the counterchanged crossed cube, this paper also analyzes the basic properties of the network, proves that the network is ...

It has recently been reported that in cold rolled copper, cube-oriented volumes are frequently found in long thin bands next to bands whose orientation is related to the cube orientation by a 30-40° rotation about a common pole. This microstructure would suggest that during recrystallisation, cube in the deformed structure can growth easily into its neighbour due to the special misorienta...

My G4G8 exchange item is a screw-together cube made of two identically shaped nylon parts, one dyed red and one dyed yellow. It can be seen as a cube sliced by the propeller of an airplane flying through it. Formally, it is cube which has been split along a helicoid surface whose axis is aligned with a two-fold axis of the cube, i.e. passing from one edge midpoint to the opposite edge midpoint....

In a series of papers, I. J. Schoenberg [1 3] studied motions inside an n-dimensional cube with side length one, centered at the origin, of a point particle which moves like a billiard ball, that is, the particle always moves along a straight line until it encounters the boundary of the cube, when it is reflected in the usual way. Only non-trivial motions, that is, ones not contained in any hyp...

It is well known that the k-ary n-cube has been one of the most efficient interconnection networks for distributed-memory parallel systems. A k-ary n-cube is bipartite if and only if k is even. Let (X,Y ) be a bipartition of a k-ary 2-cube (even integer k ≥ 4). In this paper, we prove that for any two healthy vertices u ∈ X, v ∈ Y , there exists a hamiltonian path from u to v in the faulty k-ar...

We describe an Augmented Reality system using the corners of a color cube for camera calibration. In the augmented image the cube is replaced by a computer generated virtual object. The cube is localized in an image by the CSC color segmentation algorithm. The camera projection matrix is estimated with a linear method that is followed by a nonlinear refinement step. Because of possible missclas...

A collection of Il 3-cube decompositions of a graph G is said to have intersection size t if there is a set S, with 181 = t, of 3-cubes which is contained in every decomposition, and no 3-cube which is not in S occurs in more than one decomposition. We determine all integers n, t and Il, with Il ::; 12, for which there exists a collection of Il 3-cube decompositions of Kn with intersection size...

Before methods for drawing accurately in perspective were developed in the 15th century, many artists drew with divergent perspective. But we found that many university students draw with divergent perspective rather than with the correct convergent perspective. These experiments were designed to reveal why people tend to draw with divergent perspective. University students drew a cube and isol...

Turbulent flow over wall-mounted cube in a channel was investigated numerically using Large Eddy Simulation. The Selective Structure Function model was used to determine eddy viscosity that appeared in the subgrid scale stress terms in momentum equations. Studies were carried out for the flows with Reynolds number ranging from 1000 to 40000. To evaluate the computational results, data was compa...

This paper introduces the marching cube octree data structure, a new scheme for representing and generating the mesh of various level-of-details (LODs). The marching cube octree is based on the data structure of the Marching Cube algorithm [1 ], which is used to generate the mesh from the range data and the octree, this last widely used in computer graphics. Our LOD model can support adaptive s...
