We investigate the control problem of the optimal choice of idle server (if any) for arriving customer in order to minimize the mean system time (waiting time + service time). The considered MAP/MAP/N queue consists of a common infinite buffer and multiple identical servers with MAP service processes whose phases (internal states) are known. Customers arrive according to a MAP (whose phase is a...

considering the increasing awareness and expectations of our customers in today's competitive dynamic market, enterprises must improve their level of understanding and knowledge of their market and take steps toward a deeper identification of customer needs. indeed, such organizations need to improve their sense making capabilities. companies that have high sense making capability can bett...

biglar permo-triassic bauxite deposit is located in ~15 km northwest of abgarm, southwest of ghazvin province, west of central iran. it consists of 8 stratiform and discontinuous bauxite lenses lying along the contact of ruteh (permian) and elika (triassic) carbonate formations. petrographically, the bauxite ores exhibit collomorphic-fluidal, pseudo-breccia, pseudo-porphyritic, panidio-morphic-...

This study investigated the effect of numerical customer identification (i.e., assigning numbers to identify customers) in service context on numbered customers' reaction failures. We manipulated different ways (room number, table and order number) measured tolerance services across various settings (in a restaurant, spa, café) four studies. The results demonstrated that after being identified ...

As an aggregate of cyclists, a peloton exhibits collective behavior similar to flocking birds or schooling fish. Positional analysis of cyclists in mass-start velodrome (track) races allows quantitative descriptions of peloton phases based on observational data. Data from two track races are analyzed. Peloton density correlates well with cyclists’ collective power output in two clear phases, on...

Surgical resection of pulmonary tissue exerts a proregenerative stretch stimulus in the remaining lung units. Whether this regeneration process reenacts part or whole of lung morphogenesis developmental program remains unclear. To address this question, we analyzed the stretch-induced regenerating lung transcriptome in mice after left pneumonectomy (PNX) in its developmental context. We created...
