An immersed-boundary method was employed to perform a direct numerical simulation (DNS) of flow around a wall-mounted cube in a fully developed turbulent channel for a Reynolds number Re = 5610, based on the bulk velocity and the channel height. Instantaneous results of the DNS of a plain channel flow were used as a fully developed inflow condition for the main channel. The results confirm the ...

We studied the impact of different visual objects such as a moving hand and a moving cube on the bioelectrical brain activity (i.e., electroencephalogram; EEG). The moving objects were presented in a virtual reality (VR) system via a head mounted display (HMD). Nine healthy volunteers were confronted with 3D visual stimulus presentations in four experimental conditions: (i) static hand, (ii) dy...

The calculation of the pressure field on and around solid bodies exposed to external flow is paramount importance a number engineering applications. However, conventional measurement techniques are inherently linked problems principally caused by their point-wise and/or intrusive nature. In present paper, we attempt calculate time-averaged two-dimensional integrating PIV (particle image velocim...

A 2D analytical method for magnetic vector potential calculation in inner rotor surface mounted and surface inset permanent magnet machines considering slotting effects, magnetization orientation and winding layout has been proposed in this paper. The analytical method is based on the resolution of Laplace and Poisson equations as well as Maxwell equation in quasi- Cartesian coordinate by using...

In this paper, a novel structure of a axial flux switching machines for use in wind speed turbines at low speeds has been proposed, which in addition to the previous advantages, has a simple and economical design for the production of this type of machines. In this proposed machine, the magnets are placed on the surface of stator, and the three-phase winding is located in the space between the ...

With specially arranged inducing elements on a white surface of uniform luminosity, a phenomenally complete Necker cube can be seen in any array where only the 'corners' of the cube are physically represented. The subjectively seen bars of the cube disappear when the inducing 'discs' are seen as 'holes' in an interposing surface, through which the corners of a partially occluded cube are viewed...

In this work we give an approach to analyse a surface topology complexity inside a cube in the Marching Cube (MC) algorithm. The number of the isosurface intersections with the cube diagonals is used as the complexity criterion. In the case of the trilinear interpolation we have the cubic equation on the each cube diagonal and there is a possibility to find the coordinates of the three intersec...
