Disproportionality of Black Males in Special Education: A Case Study Analysis of Educator Perceptions in a Southeastern Urban High School
… students in special education is the result of subjective testing practices and eligibility processes that stem from societal beliefs and staff biases rather than objective measures used to diagnose the presence of specific disabilities. While Black male students are historically overrepresented …

Movements in Binaural Space: Issues in HRTF Interpolation and Reverberation, with applications to Computer Music
… perform better than a minimum-phase method in subjective testing. The accurate, artefact-free dynamic source processing afforded by the above methods is harnessed in a binaural reverberation model, based on an early reflection image model and Feedback Delay Network diffuse field, with accurate …

Measuring Interactivity in Audio Teleconferencing using Conversation Analysis
… task selection and design for conversation-based testing. This work has been achieved through the implementation of a series of conversation-based subjective tests which required over 100,000 data points to be manually reviewed. This work will also consider the design of a more effective …

Ride and handling assessment of vehicles using four-post rig testing and simulation
… expensive procedure and commonly relies on the subjective judgements of test drivers to assess various aspects of ride and handling. The work in this thesis aims to create a testing and tuning technique using four-post rig testing and vehicle simulation to significantly reduce the amount of …

Head Mounted Microphone Arrays
… to be performed. Results of psychoacoustic testing with a prototype headset array are presented and examined. Subjective testing shows statistically significant improvements over occluded localization when equipped with this new transparent hearing system prototype.

Wavelet-based Image Compression Using Human Visual System Models
… quantitative metric. The performance in terms of subjective quality is typically not evaluated. Moreover, the sensitivities of the human visual system (HVS) are often not incorporated into compression schemes. This paper develops new wavelet models of the HVS and illustrates their performance for …

Experimental evaluation of the efficiencies of certain non- parametric statistics
… quality control systems for such activities as subjective testing between a control group and a group receiving some particular treatment, the effects of which cannot be measured in any definite units. In addition to information of a general nature concerning these tests, this thesis also hopes …

Design and evaluation of real-time Voice-Over-IP (VOIP) systems with high perceptual conversational quality
… is the use of adaptively scheduled off-line subjective comparison tests to efficiently and accurately learn users' subjective preferences among the alternative trade-offs in order to guide the run-time control schemes to achieve high perceptual quality. In order to illustrate the application …
