Research ArticleOpen accessIn the abstractAdhoc on Demand Multipath Reliable and Energy Aware Quality of Service Routing for Mobile Adhoc NetworksV. Thilagavathe, K. DuraiswamyProblem statement: In a mobile adhoc network, there are a number of challenges for providing quality of service routing for multimedia applications and real time applications like voice transmission. The QoS parameters considered in this study are link reliability and energy consumption. Existing studies estimate the link reliability constraint between two nodes using exponentially distributed epoch lengths. The major problem … …Journal of Computer Science, Vol. 8, Issue 2 · 7 Nov 2011 · 7,842 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComparison of the Bayesian and Maximum Likelihood Estimation for Weibull DistributionAl Omari Mohammed Ahmed, Hadeel Salim Al-Kutubi, Noor Akma IbrahimProblem statement: The Weibull distribution has been widely used especially in the modeling of lifetime event data. It provides a statistical model which has a wide variety of applications in many areas, and the main advantage is its ability in the context of lifetime event, to provide reasonably accurate failure analysis and failure forecasts especially with extremely small samples. The … …Journal of Mathematics and Statistics, Vol. 6, Issue 2 · 30 Jun 2010 · 10,955 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordProbabilistic Mechanics of Glass Suggests a Model for COVID-19 EpidemicsGabriele Pisano, Antonio Bonati, Gianni Royer CarfagniThe presented statistical model allows us to identify the degree of development of an epidemic starting from the observation of the number of deaths in the invested region, categorized by the age of the victims. Recognition of which cases are associated with the disease is not necessary, as this results from the comparison with data on deaths in pre-epidemic conditions. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 26 Jan 2023 · 8,910 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Dual Exponentiated Weibull ModelMona Mustafa ElbielyA new lifetime model with various shapes of the hazard rate function for modeling uni-modal and bimodal data sets is introduced and studied along with its statistical properties. Before using the maximum likelihood method for estimating the unknown model parameters, we assessed its performance via a simulation study. The flexibility of the new model is illustrated via plots of the … …Journal of Mathematics and Statistics, Vol. 15, Issue 1 · 29 Jun 2019 · 6,511 accessesView PDF Cite
