Queueing Systems and the Web, then present an important numerical algorithm based on the computation of Markov chains for ranking webpages. This is a modern application of Markov chains though the numerical methods used are classical.

Manufacturing and Re-manufacturing Systems,ring systems. We adopt . (HPP) policy as a production control policy. We note that in a queueing system, there are servers, customers, and waiting spaces. To model a . manufacturing system by a queueing system, one may regard a server as a machine. The customers can be regarded as the inventory of p

Markov Decision Processes for Customer Lifetime Value,ins is that the model can take into account the customers switching between the company and its competitors. Therefore customer relationships can be described in a probabilistic way, see for instance Pfeifer and Carraway . Stochastic dynamic programming is then applied to solve the optimal allo

veness of different radiations is expressed as a ratio of absorbed doses, and dose or dose equivalent are the intermediaries through which the risk from one radionuclide is estimated from risk data on another. Because of the wealth of information on the skeletal effects of radiation in humans accumu

Sociologically and technologically, it is therefore impossible to divorce metals from society. Metals featured prominently in quotidian items of everyday use; they featured strongly in religious ceremonies and were an impor
