Abstract Double-sided lapping is an precision machining method capable of obtaining high-precision surface. However, during the process thin pure copper substrate, workpiece will be warped due to influence residual stress, including stress and initial which deteriorate flatness ultimately affect performance components. In this study, finite element (FEM) was adopted study effect stress-related ...

Result and Conclusion: Data from numerical studies indicate that stress at the top of the vertical bar was larger within the scope of load; and the horizontal bar and brace participated in the work of the scaffold. The internal force that came through the two types of bars enabled us to realize the redistribution in every vertical bar in order to decrease the stress from the top to the bottom o...

A New electrical method, using charge-pumping (CP) technique under bias thermal stress (BTS), has been described in this paper. This technique is based on the charge-pumping measurement which in turn used to extract the flat-band voltage before and after an applied bias voltage at high temperature. The obtained flat band voltage shift, that is due to redistribution of the mobile ionic charges, ...

The article describes a model of interaction dynamics between a dislocation and dipolar dislocation loops. The interaction is essential for dipolar dislocation structure formation in early stages of a hardening process. For the description of the dislocation curve a direct parametric approach is employed whereas the loops are treated as rigid objects. The model equations are solved approximatel...

In the quest for the "ideal" soft tissue filler, many diverse products have been developed. The expanding market of available fillers is a testament that no one product will ideally suit all patients or clinicians. In addition, the challenge of satisfying the criteria of an ideal filler has driven researchers to take a variety of development paths. This has resulted in multiple categories to ch...

The goal of this study was to determine the prognostic utility of the exercise thallium-201 stress test in ambulatory patients with chest pain who were also referred for cardiac catheterization. Accordingly, 4 to 8 year (mean +/- 1SD, 4.6 +/- 2.6 years) follow-up data were obtained for all but one of 383 patients who underwent both exercise thallium-201 stress testing and cardiac catheterizatio...

SUMMARY We investigated the induced seismicity, source mechanisms and mechanical responses of a decametre-scale hydraulic stimulation pre-existing shear zone in crystalline rock, at Grimsel Test Site, Switzerland. The analysis reveals metre-scale complexity stimulation, which remains hidden reservoir-scale. High earthquake location accuracy allowed separation four distinct clusters, three were ...
