Heart rate, frequency of skin conductance responses, and self-reported anxiety were measured during performance of a computer version of the Stroop Color-Word Interference Test, and during a non-conflicting control task involving the color naming of color patches. Stroop and control stimuli were presented individually in order to vary task pacing. Subjects(More)
The classification accuracy of a Support Vector Machine is dependent upon the specification of model parameters. The problem of finding these parameters, called the model selection problem, can be very computationally intensive, and is exacerbated by the fact that once selected, these model parameters do not carry across from one dataset to another.

The objective of this study was to assess the ability of humans to detect the presence of DC electric field and ion currents. An exposure chamber simulating conditions present in the vicinity of high-voltage DC (HVDC) lines was designed and built for this purpose. In these experiments, the facility was used to expose observers to DC electric fields up to 50(More)
This paper introduces the Course-Petri net, a specialization of Petri net which is used as the foundation for development of an advising system, SASSY. The system suggests courses for an advisee based on (i) Frequency of the course offering (ii) Balancing the course load, (iii) Shortening the path length to graduation, (iv) Preference of advisee, and (v)(More)
