Although access to grid resources is realized through a standardized interface, independent grid resources are not only managed autonomously but are also accessed as independent entities. Such environment results in configuration differences among individual resources forcing users that access those resources to deal with the variability in resource configurations. This behaviour breaks the con...

In this paper we present a distributed discovery method allowing individual nodes to gather information about resources in a wide-area distributed system made up of autonomous systems linked together by a network technology substrate. We introduce an algorithm and a model for distributed awareness and a framework for dynamic assembly of agents monitoring neliwork resources. Whenever an agent ne...

BACKGROUND The resource-based view of the firm suggests that organizations must obtain valuable resources from external sources to obtain lasting benefits. Professional associations today exist in every industry and offer resources to assist their affiliates' organizations and individual members. Today, there are more than 23,000 national and 64,000 state, local, and regional professional assoc...

Natural zeolite was used as a bed medium for plantation of lettuce seedlings and its effects on growth and chemical composition of red tilapia and lettuce were investigated in a pisciponic system. The place of study was the Aquatic Resources Technology Laboratory, Faculty of Agriculture, at the University Putra Malaysia, in 2002. The mean individual weight and biomass of fish in the treatment w...

Studies of consumer-resource interactions suggest that individual diet specialisation is empirically widespread and theoretically important to the organisation and dynamics of populations and communities. We used weighted networks to analyze the resource use by sea otters, testing three alternative models for how individual diet specialisation may arise. As expected, individual specialisation w...

Differentiated services architecture is receiving wide attention as a framework for providing different levels of service in the Internet. Current architecture allows customers to mark their packets and the network provider to check them for conformance to service contracts. This paper looks at the problem of achieving speci®c QoS goals of individual ̄ows by ̄exibly managing resources available...

BACKGROUND Previous research suggests individual-level socioeconomic circumstances and resources may be especially salient influences on mortality within the broader context of social, economic, and environmental factors affecting urban 19th century mortality. OBJECTIVE We sought to test individual-level socioeconomic effects on mortality from infectious and often epidemic diseases in the con...
