The sharpness of the images in metallography

open access: yesЛитьë и металлургия, 2018
The article presents the issues of sharpness of images of the structure of materials in metallographic studies. The use of the concept of depth of field to obtain images of the structure of various objects – fractures, microsection polished specimen ...

A method for estimating the errors in many-light rendering with supersampling

open access: yesComputational Visual Media, 2019
In many-light rendering, a variety of visual and illumination effects, including anti-aliasing, depth of field, volumetric scattering, and subsurface scattering, are combined to create a number of virtual point lights (VPLs).

Prediction of Bridge Pier Scour Depth and Field Scour Depth Monitoring

open access: yesE3S Web of Conferences, 2018
In practice, it is a major challenge in real-time simulation and prediction of bridge pier scour depth, especially using 3-D numerical model. The simulation time spend too much to use 3-D numerical model simulation and inefficiently to predict bridge ...

Supersonic axial-force characteristics of a rectangular-box cavity with various length-to-depth ratios in a flat plate [PDF]

open access: yes
A wind-tunnel investigation has been conducted at Mach numbers of 1.50, 2.16, and 2.86 to obtain axial-force data on a metric rectangular-box cavity with various length-to-depth ratios. The model was tested at angles of attack from -4 deg to -2 deg.
