Communicating expertise in system operation and fault diagnosis to non-expertsStaderman, William P. 01 May 2003 (has links)
The use of systems that span many knowledge domains is becoming more common as technology advances, requiring expert-performance in a domain from users who are usually not experts in that domain. This study examined a means of communicating expertise (in system operation and fault diagnosis) to non-experts and furthering the understanding of expert mental models. It has been suggested that conceptions of abstract models of system-functions distinguish expert performance from non-expert performance (Hanisch, Kramer, and Hulin, 1991). This study examined the effects on performance of augmenting a simple control panel device with a model of the functions of the device, interacting with the model, and augmenting the device with graphically superimposed procedural indicators (directions). The five augmented display conditions studied were: Device Only, Device + Model, Device + Procedural Indicators, Interactive Model, and Interactive Model + Procedural Indicators. The device and displays were presented on a PC workstation. Performance measures (speed and accuracy) and subjective measures (questionnaires, NASA TLX, and structured interviews) were collected. It was expected that participants who interact with the device + procedural indicators would exhibit the shortest performance time and least errors; however, those who interacted with the simplest display (device only) were fastest and exhibited the least errors. Results of this study are discussed in terms of building a mental model and identifying situations that require a mental model. / Ph. D.

Aquifer Modeling by Numerical Methods Applied to an Arizona Groundwater BasinFogg, Graham E., Simpson, Eugene S., Neuman, Shlomo P. 06 1900 (has links)
FLUMP, a recently developed mixed explicit -implicit finite -element
program, was calibrated against a data base obtained from a portion of
the Tucson Basin aquifer, Arizona, and represents its first application
to a real -world problem. Two previous models for the same region were
constructed (an electric analog and a finite -difference model) in which
calibration was based on prescribed flux boundary conditions along
stream courses and mountain fronts. These fluxes are not directly
measured and estimates are subject to large uncertainties. In contrast,
boundary conditions used in the calibration of FLUMP were prescribed
hydraulic heads obtained from direct measurement. At prescribed head
boundaries FLUMP computed time - varying fluxes representing subsurface
lateral flow and recharge along streams.
FLUMP correctly calculated fluctuations in recharge along the
Santa Cruz River due to fluctuations in storm runoff and sewage
effluent release rates. FLUMP also provided valuable insight into
distributions of recharge, discharge, and subsurface flow in the study
area.Properties of FLUMP were compared with those of two other programs
in current use: ISOQUAD, a finite -element program developed by Pinder
and Frind (1972), and a finite- difference program developed by the U.S.
Geological Survey (Trescott, et al., 1976). It appears that FLUMP can
handle a larger class of problems than the other two programs, including
those in which the boundary conditions and aquifer parameters vary
arbitrarily with time and /or head. FLUMP also has the ability to solve explicitly when accuracy requires small time steps, the ability to
solve explicitely in certain parts of the flow region while solving
implicitly in other parts, flexibility in mesh design and numbering of
nodes, computation of internal as well as external fluxes, and global
as well as local mass balance checks at each time step.
