In this paper, we consider a discrete-time multiserver queueing system with infinite buffer size, geometric service times and a FCFS (first-come-first-served) queueing discipline. A relationship between the probability distributions of the system contents and the packet delay is established. The relationship is general in the sense that it doesn’t require knowledge of the exact nature of the ar...

We present a novel classification method for splice sites prediction using support vector machine (SVM). The method first represents input sequences by sequence-based features, including the information of the distribution of tri-nucleotides and the conserved features surrounding the splice sites characterized by Markov model. An F-score based feature selection method is then used to select inf...

This paper investigates the queueing process of a bulk service queueing system under Bernoulli schedule. It also generalizes some known scenarios concerning the choice of service and re-service types. The queueing process is studied both in discrete time and in continuous time. Performance measures are derived and used to implement an optimal management policy of the system.

The genome of MM1 (40,248 bp), a temperate bacteriophage from the Spain(23F)-1 multiresistant epidemic clone of Streptococcus pneumoniae, is organized in 53 open reading frames (ORFs) and in at least five functional clusters. Bioinformatic and N-terminal amino acid sequence analyses enabled the assignment of possible functions to 26 ORFs. Analyses comparing the MM1 genome with those of other ba...

This note presents a concurrent estimation technique that broadens the set of queueing systems where concurrent estimation techniques are applicable. Our technique utilizes a proportional relation and concurrently estimates performance measures with respect to various buffer capacity values in a queueing system. Our technique applies to a queueing system that characterizes a router/switch in pa...

Queueing network models have used lucratively to analyze the validation of multi resource system such as Computer systems and Communication Networks. This paper covenantal with the Stochastic analysis of queueing network with several classes of customers. Stochastic analysis describes the nature of the queueing networks and their applications, calculating the system performance. The measurable ...

Abstract In recent years, dramatic outbursts have been identified toward massive protostars via infrared and millimeter dust continuum molecular maser emission. The longest lived outburst (>6 yr) persists in NGC 6334 I-MM1, a deeply embedded object with no near-IR counterpart. Using FORCAST HAWC+ on SOFIA, we obtained the first mid-IR images of this field since began. Despite being undetecte...
