Image-based View Synthesis
We present a new method for rendering novel images of exible 3D objects from a small number of example images in correspondence. The strength of the method is the ability to synthesize images whose viewing position is signi cantly far away from the viewing cone of the example images (\view extrapolation"), yet without ever modeling the 3D structure of the scene. The method relies on synthesizin...
متن کاملDetecting pitting corrosion and its severity using wavelet entropy in electrochemical noise measurement
Entropy as a measure of uncertainty was used to represent the results of the wavelet technique in electrochemical noise analysis. The experimental signals were obtained by recording the electrochemical potential and current noise of 7075 aluminum alloy in 3.5% NaCl solution. The electrochemical potential and current noise were decomposed into 16 levels using Daubechies wavelets. Wavelet output ...
متن کاملDETERIORATION OF PITTING CORROSION OF 316 STAINLESS STEEL BY SENSITIZATION HEAT TREATMENT
In this research pitting Corrosion of a sensitized 316 stainless steel was investigated employing potentiodynamic, potentiostatic techniques. Sensitization process was carried out on as-received alloy by submitting the specimen in electric furnace set at 650°Cfor five hours and then the specimen was quenched 25°C water. Potentiodynamic polarization of as received and sensitized specimens in 1M ...

A significant feature of alloys is the surfaces hardness that is always accompanied by challenges when it’s measured by common mechanical techniques. In this investigation, we used Laser Induced Breakdown Spectroscopy (LIBS) as a replacement method for common mechanical techniques to measure the surfaces hardness of different alloys. After recording the spectrum of alloy samples in order to ide...
متن کاملPretreatment of Gray Cast Iron for Hard Chromium Electroplating (RESEARCH NOTES)
From the standpoint of processing, hard chromium layer plate may be applied to steels, cast iron, aluminum and nickel base alloys. Cast iron can be plated provided that the surface is capable of conducting the required current and is reasonably free of voids, pits, gross silicate inclusions, and massive segregation. There are many difficulties arising from graphite phase and deposition of hydro...
