Effect of Load, Load dependent nature of Micro hardness measurement and Doping Effect on untreated samples and Micro hardness studies on the effect of charge due to electrical stress on the samples of pure and Rhodamine doped PMMA with different weights proportions have been carried out using Vicker’s micro hardness testing for hardened networks plasticization and crystallization. Some selected...

statement of problem: there are controversial reports regarding physical and mechanical properties of resin composites and glass ionomer cements. some revealed higher strength and hardness for resin composites while others showed a comparable value for glass ionomer cements. evaluation of mechanical properties of different types of resin composites in comparison with resin modified glass ionome...

The mechanical properties of wrought iron from multiple elements of six late 19th-century truss bridges is evaluated by a program of destructive and nondestructive testing, including hardness testing and tension tests to evaluate the yield stress (Fy), tensile strength (Fu), and ductility of the material. The yield stress and tensile strengths are found to be in accordance with those published ...

High-fluence N+-implantation in steel is monitored by use of nondestructive and contactless photothermal measurements during the implantation process. The modulated reflectivity is correlated with the results of Knoop hardness testing. On-line measurements on the steel surface and direct ion beam monitoring from the back side of a monitor sample are demonstrated. The maximum of the ion implanta...

in this research, the compositing of the surface of az31b magnesium alloy with cnt was studied by fsp. the parameters under study were rotational speed (500-1500 rpm), transverse speed (12-44 mm/min), number of passes (1-4), and cnt weight fraction (0-2%). microhardness testing, optical metallography, fesem, and eds analysis were employed for the characterization of the samples. the suitable li...

This paper is about two related decision theoretic problems, nonparametric two-sample testing and independence testing. There is a belief that two recently proposed solutions, based on kernels and distances between pairs of points, behave well in high-dimensional settings. We identify different sources of misconception that give rise to the above belief. Specifically, we differentiate the hardn...

One of the fundamental problems of computational algebra is to classify polynomials according to the hardness of computing them. Recently, this problem has been related to another important problem: Polynomial identity testing. Informally, the problem is to decide if a certain succinct representation of a polynomial is zero or not. This problem has been extensively studied owing to its connecti...
