DISCUSSIONS AND SUGGESTIONS ON USING DIFFERENT POINT-TO-POINT PROTOCOLS FOR TRANSPORT AND DISPERSION MODEL EVALUATIONS
Historically, assessments of T&D models have involved comparisons to field trial data using quantities derived from
observations – maximum concentrations, plume widths, or integrated concentrations over arcs at various downwind ranges.
Recently several methodologies that compare observations and predictions paired in space and time have been developed. Two
different protocols designed to deal with low observed or predicted values have emerged. One of these protocols requires that both
the observation and the prediction must exceed a specified threshold before being considered in the comparison. The other protocol
requires that either the observation or the prediction must exceed a specified threshold before being considered in the comparison.
This presentation compares the potential effects of applying these two protocols to T&D model assessments
EVALUATION OF URBAN ATMOSPHERIC TRANSPORT AND DISPERSION MODELS USING DATA FROM THE JOINT URBAN 2003 FIELD EXPERIMENT
We have evaluated the performance of several urban atmospheric transport and dispersion models by comparing model
predictions to tracer gas concentrations measured during the Joint Urban 2003 field experiment in Oklahoma City, USA. These
models include the Urban Canopy, Urban Dispersion Model (UDM), and Micro-SWIFT/SPRAY (MSS) modes within the HPAC
modelling suite, QUIC-URB/QUIC-PLUME models, and the MESO/RUSTIC models. We discuss some of the results of these
comparisons, including relative model performance according to bias and scatter metrics, differences in model behavior for
predictions of daytime versus nighttime releases, and operational considerations such as runtime differences
Process mapping and scripting in the Accounting Information Systems (AIS) curriculum
The ability to understand, document, and suggest improvements for a business process is an important skill for an accounting student for the following reasons: (1) efficient business processes give businesses a competitive advantage; (2) business process analysis provides auditors with an assessment of business risk; and (3) successful enterprise resource planning implementation depends on understanding and improving existing business processes. It is suggested that students be introduced to process mapping and scripting in an accounting information systems (AIS) course to facilitate their understanding of business processes and help them visualize the interaction between functional areas. The specifics of process mapping are covered and advantages of incorporating process mapping into the AIS curriculum discussed. It is also proposed that scripting, which is used to facilitate configuration, testing of ERP software and communication between the accountant and the programmer, be included in the AIS course. Finally, suggestions for classroom activities are included.Business Processes, Process Mapping, Scripting, Ais Education, Ais Curriculum,
