Research ArticleOpen accessIn the abstractWarranty Cost Models using Accelerated Life Tests on Dagum DistributionEman A. El-Dessouky NassefWarranty one of the main factors which effect on the decision to purchase any product whether it is non repairable or repairable, therefore, in market the manufacturers can compete by using warranty service. The cost of warranty are wanted to predict which are mirrored on the price and profitability of products. To achieve this goal, the research is concerned with … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 3 Aug 2020 · 6,193 accessesView PDFCite
Research ArticleOpen accessIn the abstractUsing a Hierarchical Weibull model to Predict Failure Strength of Different Glass Edge ProfilesDavid Thomas Kinsella, Johan LindströmThe edge strength of glass is analyzed using a Weibull statistical framework based on 78 data samples from a range of experiments recorded in literature. Based on the analysis, a 45 MPa strength value (computed as the lower bound in a one-sided confidence interval at the 75% level for the 5-percentile in the distribution) could be conservatively used with arrised, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 30 Apr 2020 · 8,280 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Inverse Weibull Distribution: Properties and ApplicationsMona Mustafa Elbiely, Haitham M. YousofIn this work, we introduce a new flexible extension of the Inverse Weibull distribution. Some important mathematical properties of the proposed model are derived along with a numerical analysis of mean, variance, skewness and kurtosis measures of the proposed model. The performance of the maximum likelihood method is assesses via a comprehensive simulation studies in terms of mean squared errors. … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 25 Mar 2019 · 7,509 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransverse Bed-Slope, Lateral Bed-Load Rate and Bed-Load Deviation Angle in Meandering Alluvial StreamsYoussef Ismail HafezA novel expression for the deviation angle of the bed-load discharge is developed which allows its distinction with the other deviation angles of the flow velocity and boundary shear stress. A transverse bed-slope equation is developed which compares very well with experimental data and field data at the Fall River and Muddy Creek, USA. Stream-wise computations are successfully performed of … …American Journal of Environmental Sciences, Vol. 20, Issue 1 · 9 Sep 2024 · 4,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractStress Analysis of an Artificial Human Elbow Joint: Application of Finite Element AnalysisStephen K. ArmahThe elbow joint is frequently affected by two kinds of arthritis (degenerative arthritis and rheumatoid arthritis) following some kind of injuries. There have been efforts since the eighteenth century by various individuals and organizations in modeling permanent implants for the elbow joint, but some of the prostheses have been disappointing because of lack of understanding of the biomechanics of the … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 1 · 4 Jan 2018 · 9,540 accessesView PDFCite
Research ArticleOpen accessIn the abstractCavern Design Philosophy under High Stress Rock Condition a Case Study in Sri LankaBahram SalehiFor stabilizing of rock cavern stress condition and orientation, rock properties and cavern geometry have determinant effects. Numerical and analytical study and knowledge about self-support arching can assist to designer in appropriate understanding of cavern and ground interaction. The comparative studies by E. Hoek, showed that the mushroom shaped cavern was not an acceptable design because of high value stress … …American Journal of Applied Sciences, Vol. 14, Issue 3 · 21 Mar 2017 · 7,982 accessesView PDFCite
