The Aggregate Level Simulation Protocol (ALSP) concept was initiated by ARPA in January 1990, the first laboratory demonstration took place in January 1991, and the first fielding in support of a major military exercise took place in July 1992. Since then, the ALSP confederation of models has grown from the original two members to six. In support of this(More)
The venerable problem solving technique of simulation finds itself in the midst of a revolution. Where once it was regarded as a " technique of last resort " for systems analysis, today simulation is widely applied to support myriad purposes, including: training, interaction, visualization, hardware testing , and decision support in real-time.

The DOD High Level architecture (HLA) has recently become the required method for the interconnection of all DOD computer simulations. The HLA addresses the rules by which simulations are designed to facilitate interoperability, the method by which information exchanged between simulations is described, and a standard set of software services provided by a(More)
Competing demands for water have resulted in many wetlands becoming either more permanently flooded or more permanently dry. It has been stated that such changes may lead to a loss of diversity in wetland communities; yet to date, this has not been tested experimentally. In this study, we experimentally test the hypothesis that increasing the hydrologic(More)
A project is currently underway which involves testing a distributed system − the Run Time Infrastructure (RTI) component of the High Level Architecture (HLA). As part of this effort, a test suite has been designed and implemented to provide a coordinated and automated approach to testing this distributed system. This suite includes the creation and(More)
We describe a novel biotope at 633 to 762 m depth on a vertical wall in the Whittard Canyon, an extensive canyon system reaching from the shelf to the deep sea on Ireland's continental margin. We explored this wall with an ROV and compiled a photomosaic of the habitat. The assemblage contributing to the biotope was dominated by large limid bivalves, Acesta(More)
Globally, rain-fed wetlands provide critical habitat for a wide range of amphibian species, however, information on the use of rain-fed wetlands by Australian frog species is extremely limited. This study examined the distribution of frog breeding in rain-fed wetlands following the first significant rain event after a period of severe drought (2002–2009) in(More)
A new distributed test system is used to verify the Runtime Infrastructure (RTI) component of the High Level Architecture (HLA). As part of this effort, a test suite has been designed and implemented to provide a coordinated and automated approach to testing this distributed system. This paper describes the application of this test environment and its(More)
