Item A variable speed single phase wind generator(Texas Tech University, 1977-12) Tsai, Yue-guoNot availableItem Design and analysis of wheel hub to provide in-hub electric motor for HMMWV vehicle(Texas Tech University, 2004-05) Thakur, Sandeep SinghThis thesis describes the design of the wheel hub of hybrid HMMWV so as to introduce an electric in-hub motor inside the hub. Chapter I explains the consumption and detrimental effect of fossil fuels. Limitations of present alternative fuels are also explained. In Chapter 2 deals with hybrid electric vehicle concept, various types and configurations and the different military hybrid vehicles. In subsequent chapters vehicle performance characteristics such as velocity, acceleration and gradability are studied for different cases and gear ratio calculation is explained. Design constraints are listed and design was done based upon available space and taking weight factor into consideration. Further, the design was tested for the vehicle crushing forces known as 20G and 8G forces. High strength steel was used as the material for the design. Results are verified with available data for strength of the design. The Von Mises stresses are less than yield stresses in all the cases. Nodal displacements are within the acceptable range. Pro E is used for modeling the components and Algor is used for analysis.Item Optical power concentrations on aligned and misaligned receivers in solar gridiron power systems(Texas Tech University, 1978-08) Leung, HipsumA powerful strategy, the ROSA approach, has been developed for calculation of optical power concentrations produced by solar collectors. The ROSA method is yery general and can be applied to concentrators and receivers of any geometrical shape. In addition, the method can be used for light from a source of finite extent undergoing any number of multiple reflections on the collector mirror. The work presented here is applied to optical concentrations on a conical receiver suspended in a spherical segment collector as appropriate for a Solar Gridiron Power System. Optical power concentrations on both aligned and misaligned receivers are described for various solar inclinations. A simplified approach for calculating azimuthally averaged power concentrations on a perfectly aligned receiver is also presented.Item Optical-DSC for analysis of energy processes in transparent microscopic systems(2001-08) Yuan, Shuming; Diller, K.
