Effect Of Specific Data Variations On Automated Speaker Recognition, Ethan David Meighen
Effect Of Specific Data Variations On Automated Speaker Recognition, Ethan David Meighen
Graduate Theses, Dissertations, and Problem Reports (ETD)
Speaker recognition is not a new biometric modality but there are still many obstacles in the way in order for it to become as used as fingerprint recognition, facial recognition, and iris recognition. Many real-world environmental conditions, hardware device variations, and human behavior present serious challenges to the use of opportunistic voice or speaker samples for identification purposes. Non-idealities, identified as nuisance factors, include environmental noise, input device quality, length of utterance, sample rate variation, and unscripted data are common nuisance factors that can impact speaker recognition match score performance. The impact of the nuisance factors listed above were evaluated …

Flexor Dysfunction Following Unilateral Transient Ischemic Brain Injury Is Associated With Impaired Locomotor Rhythmicity, Kiril Tuntevski
Graduate Theses, Dissertations, and Problem Reports (ETD)
Functional motor deficits in hemiplegia after stroke are predominately associated with flexor muscle impairments in animal models of ischemic brain injury, as well as in clinical findings. Rehabilitative interventions often employ various means of retraining a maladapted central pattern generator for locomotion. Yet, holistic modeling of the central pattern generator, as well as applications of such studies, are currently scarce. Most modeling studies rely on cellular neural models of the intrinsic spinal connectivity governing ipsilateral flexor-extensor, as well as contralateral coupling inherent in the spinal cord. Models that attempt to capture the general behavior of motor neuronal populations, as well …
