A tandem queueing system with infinite and finite intermediate buffers, heterogeneous customers and generalized phase-type service time distribution at the second stage is investigated. The first stage of the tandem has a finite number of servers without buffer. The second stage consists of an...

In this paper, we are concerned with the analytical treatment of an GI/M/1 retrial queue with constant retrial rate. Constant retrial rate is typical for some real world systems where the intensity of individual retrials is inversely proportional to the number of customers in the orbit or only...

We consider a multi-server retrial queue with the Batch Markovian Arrival Process (BMAP). The servers are identical and independent of each other. The service time distribution of a customer by a server is of the phase (PH) type. If a group of primary calls meets idle servers the primary calls...

The California Department of Transportation (Caltrans) replaced about 5 kilometers (total 20 lane-kilometers) of concrete pavement on Interstate 15 in Devore, California. The I-15 Devore II rehabilitation project was completed in six weekend closures with around-the-clock construction in early...

The Bank of Korea is strengthening its ability to identify risk factors at an early stage by monitoring the basis of macroprudential conditions. Through its Financial Stability Report, a semi-annual statutory report, the Bank assesses macroprudential conditions, delivers early warnings, and...

This paper reviews how the changing financial environment in Korea has affected the conduct of monetary policy and examines the extent to which the Bank of Korea now uses the short-term interest rate rather than money aggregates as an operating target. Empirical results from estimation of...

This publication is part of a collection of three profiles covering nine aquatic resources-dependent villages in the provinces of Stung Treng, Takeo and Siem Reap. The profiles are important because in most, if not all, of the aquatic-resources villages of Cambodia, critical data and information...

Under the impetus of the recent global financial crisis, there has been a growing recognition that the global imbalances are a systemic problem that has a great bearing on the macroeconomic policies of a number of countries as well as on cross-border capital flows, and that they might be linked...
