چکیده

Previously we have reported on our work on coating a truncated-cone-shaped \engineering" (not high quality in terms of smoothness) mandrel and have removed the layers, intact, on the inside of an electroform with a cylindrical, truncated-cone geometry. We have advanced to using a high quality (about 0.5 nm) smooth truncated cone. We report our latest advances in re ning our fabrication techniques and the results of X-ray measurements. The X-ray measurements made at the Argonne APS SRI-CAT 2-BM-B beam-line were at 10 and 30 keV. The results showed that we had produced excellent Si/W multilayers on the inside of a 10 cm long by about 10 cm diameter truncated cone shaped mirror. We estimate the re ectivity of the layers at the primary Bragg peak to be well above 10%. We also show that the multilayers were uniform around the mirror.

Steel Coated with Cationic Poly (Ethylenimine) (PEI) and Anionic Poly (Vinylsulfate) (PVS) Polyelectrolyte Multilayer Nanofilm with Different Benzotriazole Inhibitor Concentrations

Nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. The mild steels were pretreated electrochemically to modify the mild steel surface. The modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

Study of multilayer and multi-component coatings deposited using cathodic Arc technique on H-13 hot work steel for die-casting applications

Die casting process is used since long, but even today problems like erosion, corrosion, soldering and sticking affect die life. These dies undergo thermal cyclic loads from 70 oC to 600 oC during processing. Physical Vapor Deposition (PVD) hard coating can play an important role in such extreme applications. In the present work, we report the use of Chromium based multila...

Asymptotic Theory of Locally Conic Models and its Application to Multilayer Neural Networks

This paper discusses the maximum likelihood estimation in a statistical model with unidentiÞability, using the framework of conic singularity. The likelihood ratio may diverge in unidentiÞable cases, though in regular cases it converges to a χ distribution. A useful sufficient condition of such divergence is obtained, and is applied to neural networks. The exact order for multilayer perceptrons...
