Queuing models are important tools for studying the performance of complex systems, but despite the substantial queuing theory literature, it is often necessary to use approximations in the case the system is nonmarkovian. Phase type distribution is by now indispensable tool in creation of queuing system models. The purpose of this paper is to suggest a method and software for evaluating queuin...

We argue that there is a need for culture-specific measures of identity that delineate the factors that most make sense for specific cultural groups. One such measure, recently developed specifically for Māori peoples, is the Multi-Dimensional Model of Māori Identity and Cultural Engagement (MMM-ICE). Māori are the indigenous peoples of New Zealand. The MMM-ICE is a 6-factor measure that assess...

Using a queuing approach to describe a shared memory parallel computer system, it can be considered as a parallel computer system with a shared single ready queue. This can depict a single queue parallel server queuing model. Some models that are based on probability density function have been used to model the performance of the queuing system. This paper uses recursive models to evaluate the ...

Due to the complexi ty of real-world applications, the number of da tabases and the volumes of da ta in databases have increased tremendously. With the explosive growth in the amount and complexity of data, how to effectively organize the databases and utilize the huge amount of da ta becomes important . For this purpose, a probabilistic network tha t organizes a network of databases and manage...

The JAK2V617F mutation is present in most patients with polycythemia vera (PV) and in some patients with essential thrombocythemia (ET) and myeloid metaplasia/myelofibrosis (MMM). We sought to investigate the relationship between granulocyte clonality and JAK2V617F allelic ratio. A total of 168 of 190 female patients were informative for a clonality assay at the HUMARA locus; 80% of MMM, 75% of...

It has been proved by experiments that the metal magnetic memory (MMM) NDT method can effectively detect the stress concentration of ferromagnetic metal parts. But it is still hard to evaluate the stress concentration quantitatively because of the confusion in the mechanism of MMM method. In this paper experiments are designed and carried out to investigate the relationship between the MMM sign...

The study of type III RNases constitutes an important area in molecular biology. It is known that the pac1 gene encodes a particular RNase III that shares low amino acid similarity with other genes despite having a double-stranded ribonuclease activity. Bioinformatics methods based on sequence alignment may fail when there is a low amino acidic identity percentage between query sequence and oth...

Number 51 Recently, President Reagan signed a bill to reduce federal spending over the next three years by $130 billion. Almost as soon as the ink dried, Administration officials announced that further reductions totaling about $75 billion were needed to erase the federal budget deficit by 1984. Subsequently, it became evident that even that was not enough. It is clear that these budget plans w...
