We deal with well-posedness and asymptotic dynamics of a class of coupled systems consisting of linearized 3D Navier–Stokes equations in a bounded domain and a classical (nonlinear) elastic plate/shell equation. We consider three models for plate/shell oscillations: (a) the model which accounts for transversal displacement of a flexible flat part of the boundary only, (b) the model for in-plane...

A one-dimensional divergence of the monochromatic heat flux for wall-affected attenuating thingas, is developed from general considerations. Here Ebl. K~ cy and r, respectively denote the monochromatic values of the emissive power, absorption coefficient of gas, wall emissivity and optical thickness; , E, is the second exponential integ-ral, y the -4' coordinate normal to boundary. infinite geo...

The present investigation deals with study of laminar natural convection flow of a viscous fluid over a semi-infinite flat plate inclined at a small angle to the horizontal with internal heat generation and variable viscosity. The dimensionless boundary layer equations are solved numerically for a negatively inclined plate using a very efficient marching order implicit finite difference scheme....

Automatic license plate identification has many application in traffic system like electronic toll collection, custom check points. License plate recognition basically has three steps: license plate detection, segmentation of character and plate character recognition. In the first step of number plate identification system we use vertical projection method and edge detection method for number p...

Most solar collectors in Nigeria are mounted without consideration of optimum tilt angle for maximum radiation. To address the gap, a flat plate surface collector area 0.15 m2, hinged on horizontal support quick adjustment inclination between 0 to 90o was fabricated marked out at 1o intervals telescopic leg graduated degrees. Measurement radiation varying degrees taken 12:00 noon and 2.00 pm 4 ...

The purpose of this research is to establish a scale for comfort with regard to whole-body vibration by the category judgment method. Experiments were conducted with random signals as stimuli. These stimuli consisted of three types of signal, namely stimulus F, with flat PSD (Power Spectrum Density) ranging from 1 to 100 Hz, stimulus H with PSD, which became 20 dB higher at 100 Hz than at 1 Hz,...

In the computation of turbulent flows via turbulence modeling, the treatment of the convective terms is a key issue. In the present work, we present a numerical technique for simulating two-dimensional incompressible turbulent flows. In particular, the performance of the high Reynolds κ-ε model and a new high-order upwind scheme (adaptative QUICKEST by Kaibara et al. (2005)) is assessed for 2D ...

Laser welding has been increasingly utilized to manufacture a variety of components thanks to its high quality and speed. For components with complex shapes, the welding position needs be continuously adjusted during laser welding, which makes it necessary to know the effects of the welding position on the quality of the laser welds. In this paper, the weld quality under two (flat and horizonta...

We have observed that a featureless polymer thin film on a flat plate that is separated from another flat plate by a liquid filled gap can self-assemble into a periodic micropillar array. Moreover, we have observed that if there is a pattern on one of the plates, the boundary of the pillar array will align with the boundary of the pattern resulting in single domain arrays. The phenomenon is bel...

a r t i c l e i n f o a b s t r a c t USArray has facilitated significant advancement in tomographic models and methodologies. While there persists a fundamental tradeoff between horizontal and vertical resolution due to the components of the wave train analyzed, advances in joint inversions are continuing to refine the tomographic images generated with USArray. The DNA13 model incorporates tel...
