This thesis examines, documents, and evaluates the process of designing the lighting for a production of Spring Awakening, produced by Temple University's Department of Theater. I will discuss the initial design process, the execution of the design, and evaluate the finished design. / Theater

This document sets out to describe the process of creating the artistic and technical endeavor that culminated in the lighting design for Temple University Theater's October 2015 production of Anything Goes. This is an in-depth reflection and analysis of the initial impressions, personal goals, script analysis, lighting concept, and execution that went into the creation of the design from first reading to realized design. / Theater

This Thesis presents the various materials that evolved while designing the lighting for the Theatre Arts - University Theatre's production of A Little Going Away Party. Through various meetings with production staff the design objectives and styles of the premiere production were established. We determined that the production was dealing with an upcoming death in a positive manner and that the production elements should reflect this. The lighting design created a coolly lit cellar that was warmed progressively to reflect the growth of one of the characters as the story developed. The design also aided in drawing the audience's focus to different areas of the stage when action and dialogue required it. / M.F.A.

As a growth industry, tremendous cost pressures are pushing the LED lighting market away from traditional power electronics converters and towards solutions that are more unconventional. Lower quality LED lights use simple low-cost converters, whereas high end product may add complexity in order to achieve a more dramatic energy savings. SIMO technology represents an opportunity in LED lighting to combine the low cost of single-stage converters with the energy saving capability of a two-stage, multiple string solution. This paper describes the modeling, analysis, design, and testing of a Multiple Independently Regulated Output Flyback (MIROF) converter, used in LED lighting for the purpose of multiple string control. This converter is based upon SIMO technology applied to a PFC Flyback converter. The result was the development of a novel control method and an operational demonstration unit. A cost comparison of the MIROF and a conventional two-stage driver shows a promising cost reduction benefit for the former, and comparative testing shows favorable performance of the MIROF converter compared to the two-stage approach. / Master of Science

This research effort was directed at the development of legibility prediction models for flat-panel electronic displays used under typical office illumination (i.e., fluorescent) and various phases of daylight illumination. The models are intended to permit the manipulation of candidate display technologies and pertinent display characteristics such that legibility is maximized with respect to specified viewing conditions. Further, the legibility prediction models are intended to serve as an aid to the display designer in the intelligent selection of a display device for a known application. Critical legibility parameters were identified and relevant display measurement techniques were developed. A multiple degree of freedom daylight simulation apparatus capable of simulating the desired office and daylight illumination was designed and constructed. Reading speed performance data was collected from 14 subjects representative of both an age 18 to 30 group and an age 50 to 70 group. Each subject performed a numeral identification task using seven candidate flat-panel display technologies under 120 different symbol subtense/illumination/viewing angle arrangements. In addition, complete display characterization through microphotometric and microradiometric measurements was conducted for the seven flat-panel technologies under each of the viewing conditions. The results of the experiment revealed significant differences and complex interactions among the display technologies and viewing conditions which provided an excellent basis for the development of legibility prediction models. Extensive regression analyses were performed in which the human performance data was compared to both the critical legibility parameters and the display characterization measurements. Multiple sets of technology-based legibility prediction equations were successfully derived for each age group along with a generalized flat-panel display legibility prediction model. The models developed permit the evaluation and comparison of candidate display devices based on predicted reading speed as an indicant of legibility for a specified viewing environment. The required display characterization measurements can be collected in the field or under simulated conditions using commercially available hand-held measurement devices. In the absence of specific measures, careful estimation through comparison with similar display measurements contained in this report may be acceptable for certain applications. In their final form, the legibility prediction models serve as an aid in the evaluation and selection of electronic displays for a known application. In addition, the generalized legibility prediction equation developed holds the potential for application to other similar display technologies beyond those flat-panel candidates examined in the present study. Further, use of the models may permit the evaluation of new displays and display concepts without the immediate need for purchase, prototype construction, or complicated simulation. / Ph. D.
