All ... sorry for being late again. I hope you can still accept this?
This is the last one. Greg

Web-Based Molecular Simulation using Agent-Based Modeling Techniques
Note: This poster reports on an ongoing study that began at SwarmFest
2002 (Seattle, WA) when one of the investigators presented a research
problem and requested opinions on the feasibility of using Swarm on the
study. Those opinions, along with practical advice, contributed to the
following successful results.
Natural organic matter (NOM), a heterogeneous mixture of molecules,
plays a crucial role in the evolution of soils, the transport of
pollutants, and the change of global weather. The evolution of NOM over
time is an important research area in biology, geochemistry, ecology,
soil science, and water resources. Due to its complexity and structural
heterogeneity, new simulation approaches are needed to help to better
understand the structure and the evolution of NOM. We present a new
stochastic model, implemented using Java/Swarm, which explicitly treats
NOM as a large number of discrete heterogeneous molecules. The NOM,
micro-organisms, and their environment are taken together as a complex
system, and simulated using an agent-based modeling approach. The
global properties of NOM evolution over time can be studied by
simulating the physical and chemical reactions between individual
agents with temporal and spatial properties. Unlike the previous
stand-alone simulation models, the NOM simulation model serves as an
example of E-science, in which we do science on the Web by combining
recent information technologies (Java 2 Enterprise Edition, J2EE) with
an agent-based computational approach. An intelligent Web-based
interface is developed to allow scientists to access the remote
simulation model from a standard Web browser. The Web-based interface
enables scientists to remotely provide parameters for their
simulations, start and stop the simulations, and view the results. The
initial users of the NOM simulation model includes a geographically
separated group of NSF sponsored scientists from different research
areas. A NOM collaboratory is built to promote collaboration among
these scientists and allow them to share their data and information
across distributed sites. A XML-based Markup Language, NOML, is
provided to build the XML-based Web components and facilitate Web
services development in the future.
