scholarly journals A Analysis on Queuing System with Setup Time in Revamp Process

In this paper, we study about a M/G/1 Queuing model with single stage of service. Service interrupts during the time of service. The server does not get into the repair process immediately. It gets into a Set up time stage for the prior work to be done. On completion of set up stage service, the server will get into the repair process consisting of two stages, in which first stage is compulsory and the second stage of service is optional. For the model defined, we get the steady state results in closed form in terms of the probability generating functions and all the other execution performance measures of the model defined.

Typically, Christian theology includes an understanding of human afterlife consisting of two stages. The first is a disembodied existence as an immaterial being in the time between death and resurrection. Normally, it’s affirmed that some disembodied humans go to Heaven/Paradise between one’s death and resurrection; this is a state I call The Intermediate State. The second stage is the bodily resurrection. In this paper, I focus on The Intermediate State. Though the majority of the Christian tradition affirms it, I think it’s mistaken. To show two reasons why, I argue that a traditional metaphysics of human persons deployed to explicate The Intermediate State brings with it one or the other of at least two untoward consequences for Christian theology.

The Civil Procedure Rules 1998 (CPR) require the parties to give advance notice to their opponents of all the material documentation in their control. This is done in two stages. At the first stage the parties send each other lists of documents, a process called ‘disclosure’. The second stage is ‘inspection’, which is the process by which the other side can request copies of documents appearing in the list of documents, typically with photocopies being provided by the disclosing party. This chapter discusses these processes. It covers lawyers’ and clients’ responsibilities; the stage when disclosure takes place; disclosure orders; standard disclosure; menu option disclosure; duty to search; list of documents; privilege; inspection; orders in support of disclosure; documents referred to in statements of case, etc.; admission of authenticity; and collateral use.

This paper considers the MAP/G/1 queue under N-policy with a single vacation and set-up. We derive the vector generating functions of the queue length at an arbitrary time and at departures in decomposed forms. We also derive the Laplace-Stieltjes transform of the waiting time. Computation algorithms for mean performance measures are provided.

Sheet metal parts have been widely used in industry and much information for parts has been accumulated in a database. In planning the manufacturing process of a sheet metal part, if the process plan of a similar part can be retrieved from the database, the process planning would be faster and more consistent. In this paper, an effective method of searching the sheet metal parts based on bending process similarity is proposed. This method consists of two stages. In the first stage, flat pattern drawings of the parts with the same set-up numbers are classified into several topological structures. In the second stage, the parts that possess a similar bending process to the target part are selected. The bending process similarity is defined by the grasping position of a robot gripper. The number of reposition and grasping positions are decided by taking the geometric element of the flat pattern into consideration. The effectiveness of this method is described and illustrative examples are shown.


This paper explores an investigation on Queuing framework in E-trade. Online business (electronic trade) is the acquiring and selling of product and adventures, or the transmitting of benefits or data, over an electronic system, basically the web. It is the trading of things or administrations using PC systems like Internet or online casual networks. Here the Business is led utilizing PCs, phones, fax machines, standardized tag per users, Visas, ATM or other electronic apparatuses without the trading of paper-based records or physically moving to a strip mall. It incorporates exercises, for instance, acquirement, request passage, trade handling, online installment, verification, stock control, request satisfaction, shipment, and client support. In the Queuing arrangement of E trade, the clients touches base in Batch with Reneging happens at the set-up time organize and Optional second stage where breakdown happens just as fix procedure will be done. Moreover, we accept that the clients may renege amid the Initial stage because of eagerness (Slow server) or Non-Satisfaction in acquiring the items from the specific site. At the season of Repair process, Strictly Non-acceptability of the clients is executed. The model is well analyzed and solved by supplementary variable method .The system performance measures are derived. Numerical analysis and graphical representation of the model clearly justifies the model to a fullest satisfaction.

In March 1994, 141 Aberdeen general practitioners (GPs) were surveyed to clarify why Hillylands Disabled Living Centre (DLC) appeared to receive few direct referrals from this professional group. This was carried out in two stages. The first consisted of a postal questionnaire which received a 77% response rate. This identified that 90% of the 108 respondents knew of Hillylands' existence but only 24% were fully aware of the services it offered. Forty-six per cent had advised someone to visit Hillylands DLC, although only 17% of GPs had visited the centre themselves. The second stage, a telephone interview of 46 volunteer GPs, indicated that some GPs recognised a need to increase their awareness. Some felt that it was not appropriate that they visit Hillylands DLC, although those who had done so had found their visit useful. Recommendations are made to extend the mailing list at Hillylands and to set up a monitoring system to ensure regular liaison and supply of publicity material. It is also suggested that the feasibility of developing a comprehensive publicity initiative be investigated.


In a recent paper Gayler (1937) has dealt with the various theories of age hardening and has put forward the view that ageing takes place in two stages: in the first stage the solute atoms diffuse to planes about which precipitation proper will ultimately take place, and this gives rise to an increase in resistance to deformation and an increase in electrical resistivity without change in lattice parameter. The second stage follows the first and takes place nearly simultaneously. Some of the diffusing atoms will form molecules gradually form groups which will tend to produce a gradual decrease in resistivity and a diminution in the rate of hardening. When the molecular groups have grown to such an extent that the parent solid solution can no longer withstand the stresses set up, release of these stresses is caused by rejection of the groups, i. e. precipitation proper takes place. Once precipitation has set in them, according to Gayler's view, softening should begin. This theory tends to combine the "Knot" theory (Gayler and Preston 1932), which states that age-hardening occurs due to the formation of clusters or groups of atoms inside the parent lattice (the first stage, according to Gayler), and the precipitation theory (Merica and other 1919) which attributed hardening to the presence of large numbers of precipitated particles, probably ultramicroscopic in size, dispersed throughout the material. Naturally the formation of clusters or knots will occur at a lower temperature than precipitation, so that at low temperatures hardening will occur by the mechanism of the first stage. At high temperatures hardening may take place due to precipitation, the first stage being masked entirely. The question as to which of the tow processes is likely to be more effective in any particular alloy when heat-treated to give the maximum hardness obtainable in the hardening range is not specifically dealt with by Gayler, although it is stated that the experimental evidence available suggests that the second stage is, in general, more important. The work of Cohen (1936) on the silver-copper alloy containing 7∙5 % copper supports this contention, since his results show that hardening due to knot formation even at low temperatures (100-150°C) is very small indeed.

The objective of this study is to propose, implement, and test a framework of assigning relevant Library of Congress (LC) subject headings to tweet messages. In this study, the task of assigning LC headings is considered an automatic classification task that identifies relevant LC subject headings for given tweets. The classification task is conducted in two stages. In the first stage, tweets are clustered so that similar tweets are grouped together. In the second stage, the degree of similarity between a cluster of tweets and LC subject headings is measured by a popular similarity metric, Jaccard Coefficient (JC). In this pilot study, five selected tweet clusters and nine LC subject headings were carefully chosen and used. This pilot study demonstrates a positive result forthe proposed approach of identifying subject headings for tweets. In three cluster cases out of the five, JC selected the most relevant headings as the largest degrees of similarity. For the other two cases, JC was not successful in ranking the most relevant within the top three headings. In the next step, a more sophisticated clustering method will be explored and applied. Also, all possible LC subject headings will be employed to identify LC subjects for tweets in the next steps of this study.
