We describe a simple load-measure-model method for analyzing the scalability of distributed virtual environments (DVEs). We use a load simulator and three metrics to measure a DVE's engine with varying numbers of simulated users. Our load simulator logs in as a remote client and plays according to how users played during the conducted user study. Two quality of virtuality metrics, fidelity and consistency,...
The phytochemical investigation of Trichodesma amplexicaule guided by bioassay, to isolation of triterpenoids and aliphatic phytoconstituents. To evaluate the anti-inflammatory activities of isolated phytoconstituents, models with carrageenan-induced acute arthritis and complete Freund's adjuvant (CFA)-induced chronic arthritis in rats were conducted. The investigated results showed that alkanoic...
The cognitive agent architecture (Cougaar) is a distributed agent architecture framework originally developed to build large scale logistics applications for the Department of Defense. In order to facilitate rapid development of complex military and commercial Cougaar applications, we are devising "recipes" on how to automate the Cougaar application development process. The envisioned Cougaar...
