Complex environments for ATM based telecommunication services assume high availability and reliability of the network resources as well as the services. In order to reduce the cost of building and maintaining wide area ATM networks, efficient and cost-effective resource management techniques are needed to avoid over-allocation of resources. This requires building a network having the intelligen...

Optical burst switching (OBS) technology is one of the promising solutions for the next generation Internet backbones. One of the major issues in the design of optical burst-switched networks is the estimation of the availability of network resources needed for the transmission of an input traffic while ensuring the required quality of service (QoS). A few works have addressed the availability ...

BACKGROUND The school food environment is important to target as less healthful food and beverages are widely available at schools. This study examined whether the availability of specific food/beverage items was associated with a number of school environmental factors. METHODS Principals from elementary (n=369) and middle/high schools (n=118) in British Columbia (BC), Canada completed a surv...
