Item Advancing lighting for aquaria(2014-05) Wittke-Bender, Dawn Marie; Habeck, Michelle M.In this thesis I will explore the creation of a professionally advanced aquatic lighting fixture that will offer more flexibility than is currently available in the professional aquatic lighting field. I will investigate how the flexible fixture can enhance aquatic microenvironments through application of a design approach. In this investigation I will focus on the visual composition of light within the aquarium, while providing physiologically supportive light to the living inhabitants of the microenvironment. In order to explore this process I will create a LED aquatic lighting unit that shares many of the properties of a traditional theatrical lighting grid; specifically: flexible positioning, focusability of light sources, color control, and intensity control. I will design and build this flexible unit, and demonstrate its capabilities on a minimum of three contrasting aquatic microenvironments. The project will be displayed in an exhibit within the Winship Theatre building, where the human viewing environment will be designed to provide a soothing light and sound enhanced experience.Item Bruce Goff: the luminous environment in selected residential designs(Texas Tech University, 1986-12) Anderson, Georgina Marie LairdNot availableItem Cine-anim?: adaptations of realistic lighting styles(Texas A&M University, 2005-11-01) Trinh, Ellen Man NgocAnim?, a style of Japanese animation, has begun to evolve into more than a simple animation. The stories found in anim? have reached a level of complexity similar to traditional cinema. However, lighting in anim?, has been minimal. Using computers to create anim?, rather than creating it traditionally by hand, has allowed greater opportunities to be creative with lighting. Color and computer-generated (CG) effects can be integrated with traditional line drawings to create beautiful images in anim?. Since cinematic lighting exhibits some of the finest examples of lighting, this thesis will analyze lighting styles from three different cinematographers and adapt them to three anim??e style scenes in 3D. The scenes will be modeled, lit, and rendered using Alias/Wavefront MAYATM, and textured using Adobe PhotoshopTM. The result will be a visual CG piece that adapts the lighting style of certain distinctive cinematographers, while retaining the look of anim?.Item Computer classroom wall color preference and personality type of college students(Texas Tech University, 2003-08) Wang, HongWith the advent of the digita! era, computers are commonly used in teaching and leaming systems. The computer classroom is widely used in colleges and high schools in the United States. In order to create a more comfortable and effective teaching and studying environment, the most desirable wall colors for a computer classroom were identified in this study. Also, interior design students' classifications, and personality types were tested to determine if these factors have impact on their wall color preference. Two instmments were used: the Wall Color Preference Test, and the Myers-Briggs Type Indicator. The population for this study were 145 undergraduate students majoring in interior design at a university located in the southwestem United States. Students were asked to voluntarily participate in the Wall Color Preference Test. For this test, students ranked 15 slides displayed on a screen that depicted the same computer classroom and under the same lighting condition (8 parabolic fluorescent lighting fixtures) but with 15 different wall colors. The students also completed the Myers-Briggs Type Indicator. Personality type was examined in regards to its influence on preference for interior color applications. A pilot study using the same methodology was conducted prior to the population test in order to identify any problem with the questionnaire and with the procedure selected to coUect data. Data from the study were analyzed by using one-way repeated measure analysis of variance (ANOVA), Boferroni HSD post hoc test, and bivariate correlation analysis to detemiine overall preference and to reveal relationships between students' personality types, classifications and knowledge background have on their preference for wall colors of computer classrooms. The results determined that the interior design students do have color preference for the 15 images. The results also revealed that students' classifications, knowledge background had impact on colors used in image2, 6, and 12, but not on others. Results also found that students' personality types had no impact on their wall color preference for a computer classroom. This study suggested cool colors in the Master Palette Color System are more desirable colors for walls of a computer classroom.Item Correlation of moment capacity with material properties of transformer bases(Texas Tech University, 1997-12) Kumar, RiteshUntil the early 1970's, the light poles on the highways were directly fixed to the concrete foundation with the help of a base plate and bolts. Increasing fatality rates during vehicular impact on steel or concrete poles installed on the U.S. highways concerned the highway authorities. Out of this consideration evolved the concept of breakaway supports. The breakaway supports are placed between light poles and foundations, are made up of an aluminum alloy which has a certain strength, are brittle and can be molded. Since these bases house the transformers, they are also called transformer bases (t-bases). Initially, the t-bases had a height of 20 inches that was based on the 1975 American Association of State Highway and Transportation Officials (AASHTO) standard. In 1990, the Federal Highway Administration (FHWA) adopted a more stringent 1985 AASHTO light pole/t-base breakaway requirement, due to which t-bases of height 17 inches were manufactured. The new standard also required that the t-bases should be more fragile, but resist certain wind loads in addition to the breakaway requirements. Figure 1.1 shows an actual t-base installed in the field.Item Creating computer generated scene lighting in the style of Edward Hopper(Texas A&M University, 2008-10-10) Jo, Hee YeonThe goal of this thesis is to study the lighting styles used in three selected Edward Hopper paintings: Morning Sun, Summer Evening, and Night Windows and to create an original, three-dimensional scene lit in a similar style. For a general understanding of the reference paintings, visual analyses were conducted before studying the lighting styles depicted in them. During the process of conducting this lighting study, the lighting styles in the three reference paintings were closely examined and digitally reproduced. The artistic inspiration gained from these three paintings and the lessons learned from the reproduction process are integrated into the creation of the original work which serves as the final project of this thesis. Consequently, the final project displays the lighting style represented in those of the reference paintings, refined by this researcher? s own style. This study defines an approach to develop the digital lighting that can dramatically enhance the moods in realistic scenes referenced by lighting in the three Hopper? s paintings.Item Elvis Machine : the making of a machine(2012-05) Doyle, Rowan Michaela; Isackes, Richard M.; Mickey, Susan EThis thesis explores the creation of Elvis Machine, a production that was created by The Duplicates Theater Company and premiered at the 2012 Fusebox festival in Austin, Texas. This paper examines the company’s history, process and work in relation to this production.Item Home lighting and educational planning(Texas Tech University, 1978-08) Smith, Marjorie WilhelmNot availableItem Light transport simulation in reflective displays(2012-05) Feng, Zhanpeng; Nutter, Brian; Mitra, Sunanda; Karp, Tanja; Gale, Richard O.; Westfall, Peter H.In the last several years, reflective displays have gained substantial popularity in mobile devices such as e-readers, because of their significant advantages in power consumption and sunlight readability. A typical reflective display consists of a stack of optical layers. Accurate and efficient simulation of light transport in these layers provides valuable information for optical design and analysis. Physically based ray tracing algorithms are able to produce simulation results that mirror the real world display performance in a wide range of illumination conditions, viewing angles, and distances. These simulation outcomes help system architects make far reaching decisions as early as possible in the design process. In this dissertation, a reflective display is modeled as a layered material, with a FOS (front of screen) layer on the top, a diffusive layer (diffuser) underneath the FOS, a transparent layer (glass) in the middle, and a wavelength-dependent reflective layer (pixel array) at the bottom. A set of simple and efficient spectral functions is developed to model the reflectance and absorption of FOS. A novel hybrid approach combining both spectro-radiometer based and imaging based measurement methods is developed to acquire high resolution reflectance data in both angular and spectral domains. A BTDF (bidirectional transmittance distribution function) is generated from the measured data to model the diffuser. A wavelength dependent BRDF (bidirectional reflectance distribution function) is used to model the pixels. Realistic light transport simulation requires interplay of three factors: surface geometry, lighting, and material reflectance. Monte Carlo ray tracing methods are used to link these factors together. Path tracing is employed to provide unbiased results. Stratified sampling and importance sampling are used for effective variance reduction. Stratified sampling produces well distributed random samples, and importance sampling helps Monte Carlo simulation converge more quickly. Different importance sampling methods are compared and analyzed. Simulation results of display performance, including reflectance, color gamut, contrast ratio, and daylight readability, are presented. The impact of different lighting conditions, diffusers, and FOS designs are studied. Measurement data and physically based analyses are used to confirm the validity of the simulation tool. The simulation tool provides the desired accuracy and predictability for display design in a wide range of lighting conditions, which makes it a valuable mechanism for display designers to find the optimal solution for real world applications.Item Lighting preferences of female shoppers on women's specialty retail store merchandise displays(Texas Tech University, 1999-12) Linsey-Arze, Karrie AnnAccent lighting is used to add visual impact to displays and compel the customers' attention. Large amounts of money are invested in retail lighting systems every year, making it imperative that retailers are sure their lighting costs produce a return on investment. The purpose of this research was to investigate what type of lighting enables merchandise from a women's specialty retail store to look most appealing to its customers. The experimental design used in this study is a one-shot design in which three forms of lighting are manipulated. The experiment took place in the Human Sciences building at Texas Tech University. The sample was drawn from the female faculty and staff (N=2061) within the Texas Tech University main campus system, and was composed of those with a minimum age of 21. The sample was asked to view three merchandise displays which were exactly alike except for the lighting being used. Participants were asked to complete a questionnaire after viewing the displays. Analysis was performed using the MANOVA test. Results showed that overall, participants preferred the metal halide and the tungsten halogen lamps over the fluorescent lamp.Item Wing it(2016-05) Sung, Po-Yang; Habeck, Michelle M.; Isackes, RichardThe purpose of this thesis is to explore the design of an airport wing in Taipei, Taiwan to provide a space in which services are provided to a variety of people from a global community. The terminal will service international travel and will consist of eight gates, twelve check in counters and four luggage claims designed for the Taiwanese airline carrier China Airlines.
