A Single Interruption
نویسنده
چکیده
Traffic queue formed when a stochastic vehicle stream is interrupted by a single duration of blockage, or of red signal, is analysed. It is assumed that the delayed vehicles depart with constant intervals when the interruption is terminated. The probability distribution of the number of delayed vehicles, the moments of that distribution and the expected total delay are obtained using Wa1d's identity in sequential analysis. The expressions for those quantities are rigorous with a Poisson input stream and are approximated with the general input stream. In addition, the influence of initial condition of interruption is discussed with relation to the bounds on mean number of delayed vehicles.

Analysis of a Single Server Queue with Working Vacation and Vacation Interruption
In this paper, an M/M/1 queue with working vacation and vacation interruption is investigated. The server is supposed to take a working vacation whenever the system becomes empty and if there are at least N customers waiting in the system at a service completion instant, vacation interruption happens and the server resumes a normal working period. A matrix geometric approach is employed to obta...
متن کاملSingle Server Bulk Queue with Service Interruption, Two Phase Repairs and State Dependent Rates
This paper reports a study on a single server queue with bulk arrival and bulk service patterns wherein the incoming traffic depends on the state of the server which may be in operating or breakdown state. The repair of the breakdown server is performed in two phases. The operating duration of server, repair duration of both phases of repairing as well as job's inter-arrival times and service t...
متن کاملEvaluation of Probiotic Survivability in Yogurt Exposed To Cold Chain Interruption
In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb-12 or L. rhamnosus HN001 or L. paracasei...
متن کاملInnovation of a method to decrease interruption time during treatment of pelvic area carcinomas
Background: The presence of small intestine in the radiation field during pelvic cancers treatment causes an interruption in radiotherapy. A non-invasive method was developed to exclude small intestine during conventional radiotherapy. Materials and Methods: The incidence of the radiation therapy interruption is highly dependent upon the area of the small intestine included in the portals and i...

متن کاملInterruption-deficient mutants of bacteriophage T5: analysis of single-site mutants.
The properties of viable mutants of bacteriophage T5 that lack, singly, each of the four major sites at which single-chain interruptions normally occur in T5 DNA are described. The mutations responsible for loss of each interruption were mapped by analysis with HhaI, a restriction endonuclease with a cleavage site (pGCGC) that occurs at the 5' termini of the major interruptions (B. P. Nichols a...
