DEPARTURES FROM A QUEUE WITH MANY BUSY SERVERS

by Ward Whitt , 1984
"... To analyze networks of queues, it is important to be able to analyze departure processes from single queues. For the Mf M/s and M/G/«i models, the stationary departure process is simple (Poisson), but in general the stationary departure process is quite complicated. As a basis for approximations, th ..."

, this paper shows that the stationary departure process is approximately Poisson when there are many busy slow servers in a large class of stationary G/GI/s congestion models having.; servers, infinite waiting room, the first-come first-served discipline, and mutually independent and identically distributed

Data Mining: Concepts and Techniques

by Jiawei Han, Micheline Kamber , 2000
"... Our capabilities of both generating and collecting data have been increasing rapidly in the last several decades.

A Survey of Approaches to Automatic Schema Matching

by Erhard Rahm, Philip A. Bernstein - VLDB JOURNAL , 2001
"... Schema matching is a basic problem in many database application domains, such as data integration, E-business, data warehousing, and semantic query processing. In current implementations, schema matching is typically performed manually, which has significant limitations. On the other hand, previous ..."

A model of growth through creative destruction

by Philippe Aghion, Peter Howitt , 1990
"... This paper develops a model based on Schumpeter's process of creative destruction. It departs from existing models of endogeneous growth in emphasizing obsolescence of old technologies induced by the accumulation of knowledge and the resulting process or industrial innovations. This has both ..."

a tendency for laissez-faire economies to generate too many innovations, i.e too much growth. This "business-stealing" effect is partly compensated by the fact that innovations tend to be too small under laissez-faire. The model possesses a unique balanced growth equilibrium in which

Inflation and Growth

by Robert J. Barro , 1996
"... In recent years, many central banks have placed increased emphasis on price stability. Monetary policy—whether expressed in terms of interest rates or growth of monetary aggregates—has been increasingly geared toward the achievement of low and stable inflation. Central bankers and most other obs ..."

QoS-aware middleware for web services composition

by Liangzhao Zeng, Boualem Benatallah, Anne H. H. Ngu, Marlon Dumas, Jayant Kalagnanam, Henry Chang - IEEE TRANS. SOFTWARE ENG , 2004
"... The paradigmatic shift from a Web of manual interactions to a Web of programmatic interactions driven by Web services is creating unprecedented opportunities for the formation of online Business-to-Business (B2B) collaborations. In particular, the creation of value-added services by composition of ..."

"... ABSTRACT Using dealer's quotes and transactions prices on straight industrial bonds, we investigate the determinants of credit spread changes. Variables that should in theory determine credit spread changes have rather limited explanatory power. Further, the residuals from this regression are ..."

like Treasury bonds, and (2) low-grade bonds are more sensitive to stock returns. The implications of these studies may be limited in many situations of interest, however. For example, hedge funds often take highly levered positions in corporate bonds while hedging away interest rate risk by shorting
