In this article, we exploit the Bayesian inference and prediction for an M/G/1 queuing system with optional second re-service. A service unit attends customers arriving following a Poisson process and demanding service according to a general distribution and some of customers need to re-service with probability "p". First, we introduce a mixture of truncated Normal distributions on to approxima...

This document provides guidelines for mapping service classes, and traffic management features and parameters between Internet and ATM technologies. The service mappings are useful for providing effective interoperation and end-to-end Quality of Service for IP Integrated Services networks containing ATM subnetworks. The discussion and specifications given here support the IP integrated services...

Most current autonomous mobile service robots are either expensive commercial platforms or custom manufactured for research environments, limiting their availability. We present the design for a lowcost service robot based on the widely used TurtleBot 2 platform, with the goal of making service robots affordable and accessible to the research, educational, and hobbyist communities. Our design u...

A multiple optional vacation policy for the unreliable server batch arrival queueing system with essential and multi optional services under N-policy is investigated. According to vacation policy, the server takes an essential phase of vacation after the completion of service of an individual customer when queue becomes empty. On returning from the vacation, if the server finds the queue empty,...

In this paper, we consider a two-phase queueing system with impatient customers and multiple vacations. Customers arrive at the system according to a Poisson process. They receive the first essential service as well as a second optional service. Arriving customers may balk with a certain probability and may depart after joining the queue without getting service due to impatience. Lack of servic...

This study explored how pre-service teachers integrated literacy in middle level social studies. This study was conducted in the context of the Common Core State Standards (CCSS) and their focus on disciplinary literacy, the Council for the Accreditation of Educator Preparation (CAEP) Standards and their focus on rich clinical experiences, and concepts of interdisciplinary and integrated curric...

This paper examines the Bernoulli admission control policy for the two phase bulk arrival retrial queueing system wherein the customers has the option either to take second phase of service or to leave the system after completing first essential phase of service. In addition, the arrival rate of the customers depends upon the server status. After the service completion of each individual custom...

We consider a discrete-time Geo/G/1 retrial queue with starting failures in which all the arriving customers require a first essential service while only some of them ask for a second optional service. We study the Markov chain underlying the considered queueing system and its ergodicity condition. Explicit formulae for the stationary distribution and some performance measures of the system in ...
