The perceived depth of regions within a stereogram lacking explicit disparity information can be captured by the surface structure of regions where disparity is explicit: stereo capture. In two experiments, observers estimated surface curvature/depth of an untextured object (a 'ribbon') superimposed on a cylinder textured with dots, the cylinder curvature being defined by disparity (stereo dept...

an s-curve to describe the gradual transition between exhaust pressure and intake or inlet pressure. The start of compression, which marks the end of the intake process, does not necessarily occur at the same time as the close of the intake valve (IVC). The intake valve closes after bottom center (BC) while the volume in the cylinder is decreasing. The engine speed determines the point at which...

Creep behavior of thick-walled functionally graded cylinder consisting of AlSiC and subjected to internal pressure and high temperature has been analyzed. The functional relationship between strain rate with stress can be described by the well known threshold stress based creep law with a stress exponent of five. The effect of imposing non-linear particle gradient on the distribution of creep s...

We report three-dimensional direct numerical simulations of the turbulent flow between counter-rotating concentric cylinders with a radius ratio 0.5. The innerand outer-cylinder Reynolds numbers have the same magnitude, which ranges from 500 to 4000 in the simulations. We show that with the increase of Reynolds number, the prevailing structures in the flow are azimuthal vortices with scales muc...

in this paper, an analytical solution for computing the linear plastic stresses and critical pressure in a fgm hollow cylinder under the internal pressure due to non-axisymmetric loads is developed. it has been assumed that the modulus of elasticity was varying through thickness of the fgm material according to a power law relationship. the poisson's ratio was considered constant throughou...

In this paper we develop a method to parameterize tubular surfaces onto the cylinder. The cylinder can be seen as the natural parameterization domain for tubular surfaces since they share the same topology. Most present algorithms are designed to parameterize disc-like surfaces onto the plane. Surfaces with a different topology are cut into disc-like patches and the patches are parameterized se...

A sequence of rainbows is produced in light scattering by a particle of high symmetry in the short-wavelength limit, and a supernumerary interference pattern occurs to one side of each rainbow. Using both a ray-tracing procedure and the Debye-series decomposition of first-order perturbation wave theory, I examine the spacing of the supernumerary maxima and minima as a function of the cylinder r...

The numerical simulation of the three-dimensional flow upwind of a vertical cylinder over a flat plate is achieved with a parallel LES code which is called DNSUTA Version III. The preliminary computational results with a coarse grid find that the flow structure is similar to experimental observations. The bow shock is very clear, and a separation shock is formed ( Λ -structure). Inside the sepa...

The cylinder (of radius a) and the plates of the capacitor (in the planes y = ±b) can move independently and without friction in the x-direction, where the z-axis is that of the cylinder. That axis can be electrically charged with the opposite sign to that of the cylinder such that the cylinder as a whole has zero charge. The (linear, isotropic) medium between the capacitor plates, including th...

A new implicit monotonized scheme of second-order accuracy and Newton's method for solving the grid equations approximated the Navier-Stokes equations were developed to simulate the two-dimensional hypersonic viscous flow about a plate located in the wakes of a cylinder. The strong influence of the geometrical factor of interference between a plate and a cylinder (characterized by the normalize...
