BACKGROUND The Deepwater Horizon (DH) blowout resulted in fisheries closings across the Gulf of Mexico. Federal agencies, in collaboration with impacted Gulf states, developed a protocol to determine when it is safe to reopen fisheries based on sensory and chemical analyses of seafood. All federal waters have been reopened, yet concerns have been raised regarding the robustness of the protocol ...

In group communications, we find that current multicast protocols are far from “one size fits all”: they are typically geared towards and optimized for particular scenarios. As a result, when deployed in different scenarios, their performance and overhead often degrades significantly. A common problem is that most of these protocols incur high overheads with a high density of group members and ...

This paper is concerned with the use of patterns to support the development of software for reliable, resource-constrained, embedded systems. The specific focus is on systems with a time-triggered architecture in which task pre-emption can occur. The paper introduces one new abstract pattern (CRITICAL SECTION), and four new design patterns (DISABLE TIMER INTERRUPT, RESOURCE LOCK, PRIORITY INHER...

We propose a framework called \World Trade League," which is expected to become a standard problem in multi-agent economics. The rst purpose of World Trade League is to propose a network game in the context of economic and social systems. Such a game in World Trade League is executed by several players (countries), where each of country consists of heterogeneous agents such as product makers, s...
