This paper examines the relationship between various types of corn research and development (R&D) and corn prices in the United States through a fixed effects panel data model. This research explores R&D investment from both nonprofit and for-profit institutions and the effect these have corn prices. In addition, we look at the effect that corresponding exogenous changes in corn prices have on ...

CHIMERE is a chemical transport model widely used within the air quality scientific community. The actual version of CHIMERE is coupled with the MM5 mesoscale meteorological model. To facilitate model development, MM5 is replaced here with the Weather Research and Forecasting (WRF) model. With the accuracy of air quality models being highly dependent on the quality of meteorological drivers, th...

This paper reports on an effort to integrate symbolic and mathematical models to tailor the optimal output of an operations research model to tlie particular domain of a decision maker. AESOP combines tlie Blacli-Scholes model of stock options pricing with an expert system; the integrated model is designed for use by an options specialist on the American Stock Exchange. The specialist makes a n...

Modeling and simulation of military operational concepts has historically been exceedingly difficult and costly. This is in part due to the inherent complexity of military operations. This paper discusses a method of analysis, AgentBased Modeling, which brings an appropriate level of complexity to the task of evaluating military operational concepts. Techniques for military concept development ...

High frequency observations from a field campaign have been compared with time-step precipitation in the WRF regional climate model. Two microphysical schemes of different levels of sophistication have been tested. Both of the schemes generally reproduce the observed precipitation, yet the produced level of wetness is somewhat high, and the intensities rather low. Typical simulated intensities ...
