Analyses of a Markovian queue with two heterogeneous servers and working vacation
This paper analyzes an M/M/2 queueing system with two heterogeneous servers. Both servers goes on vacation when there is no customers waiting for service after this server 1 is always available but the other goes on vacation whenever server 2 is idle. The vacationing server however, returns to serve at a low rate as an arrival finds the other server busy. The system is analyzed in the steady st...
متن کاملBiclustering with heterogeneous variance.
In cancer research, as in all of medicine, it is important to classify patients into etiologically and therapeutically relevant subtypes to improve diagnosis and treatment. One way to do this is to use clustering methods to find subgroups of homogeneous individuals based on genetic profiles together with heuristic clinical analysis. A notable drawback of existing clustering methods is that they...

متن کاملPortfolio Performance Evaluation in a Modified Mean-Variance-Skewness Framework with Negative Data
The present study is an attempt toward evaluating the performance of portfolios using mean-variance-skewness model with negative data. Mean-variance non-linear framework and mean-variance-skewness non- linear framework had been proposed based on Data Envelopment Analysis, which the variance of the assets had been used as an input to the DEA and expected return and skewness were the output. C...
متن کاملA Multiplicative Random Regression Model for Test-Day Data with Heterogeneous Variance
Finnish genetic evaluation of dairy cattle is based on test-day (TD) yields, applying a multiple-trait random regression TD model. The model considers the first lactation milk, protein, and fat yield, plus the later lactation milk, protein, and fat yield as different traits, where all the later lactations are modelled as repeated observations (Lidauer et al., 2000). Currently, yields are scaled...
