The UA Campus Repository is experiencing systematic automated, high-volume traffic (bots). Temporary mitigation measures to address bot traffic have been put in place; however, this has resulted in restrictions on searching WITHIN collections or using sidebar filters WITHIN collections. You can still Browse by Title/Author/Year WITHIN collections. Also, you can still search at the top level of the repository (use the search box at the top of every page) and apply filters from that search level. Export of search results has also been restricted at this time. Please contact us at any time for assistance - email repository@u.library.arizona.edu.

| dc.description.abstract | Accurately and consistently determining depth of anesthesia during surgical procedures is a significant problem. A more objective technique than traditional methods is required. Different concentrations of anesthetic drugs have been shown to affect the Electroencephalograph; results, however, are inconsistent when using only visual inspection of the EEG. An automated technique using Neural Networks for classifying anesthetic depth from EEG data is proposed. Neural Networks are reviewed. Reasons for choosing a Backpropagation Network (BPN) are discussed. Ambiguities in previous BPN research are presented. Over 3,000 networks are formed, demonstrating training and classification properties while altering network topologies, parameters and performance criteria. Tests are performed on the Power spectrum and Phase portions of the EEG data. Optimal BPN parameters and topologies are shown. Results are compared with a statistical paradigm. | |
