AA7050 is an aluminum alloy with superior mechanical properties; however, it prone to hot tearing (HT) during its production via direct-chill casting. This study focuses on extracting constitutive parameters of the thermomechanical behavior in semi-solid state as well gaining insight failure behavior. Tensile tests were performed using Instron 5944 at solid fractions between 0.85 (550 °C) and 1...

The shape parameter estimation using the minimum-variance linear estimator with hyperparameter (MVLE-H) method is believed to be effective for a wear-out failure period in small sample. In process of estimation, our uses and estimate parameters MVLE-H method. To obtain optimal c, it takes long time, even case main purpose this paper remove restriction samples. We observed that if we set paramet...

Aim: The chief aim of this study was monitoring laboratory parameters chronic kidney failure in elderly patients. Methods: All samples were taken and processed by standard methods according to the principles good practice. Data collected an organized systematic manner form a questionnaire with respect ethical as such analyzed statistical tests analyses (Student's t-test, Analysis variance-ANOVA...
