One of the main challenges on the creation of glass pieces in casting, is to obtain a surface of the glass as clean as possible, without adhering residues, or devitrification. In glass Sculptures where the surface is not flat, the polishing process becomes very complicated, and …

Nusselt numbers and discharge coefficients were measured for a square array of confined, in-line, submerged, cylindrical jets impinging onto a normal target surface at distances ranging from greater than to less than one jet diameter. Jet-to-jet spacing was varied from two to fo…
Solar energy is one of the most promising energy sources in the world. The amount of sun's radiation reaching the earth's surface can be utilized for producing power. The conversion of solar energy to electrical energy is attainable by the utilization of Photovoltaic (PV) techno…
Three studies examined the microenvironment, heat stress, sweat rate, cooling response and psychological factors associated with wearing Islamic athletic clothing (IC) in various ambient environments. A detailed review of the literature addressing practical considerations of ath…
Advanced thermal management systems for internal combustion engines can improve coolant temperature regulation and servo-motor power consumption to positively impact the tailpipe emissions, fuel economy, and parasitic losses by better regulating the combustion process with multi…
The development of TES applications and materials takes the attention of many researchers, but the current literature rarely involves studies concerning medium temperature applications. This thesis compares available phase change materials (PCMs) for the medium temperature range…
Here we document and explain a general trend in the performance of refrigeration and heat pump systems: larger installations are more efficient. We show analytically why the performance of the system must increase with the size of the installation. The second law efficiency of r…
Aqueous lyotropic liquid crystals (LLCs) comprise a class of ordered morphologies formed by self-assembly of amphiphiles in water. LLCs assume a variety of concentration- and temperature-dependent structures including lamellae (bilayers), bicontinuous networks, hexagonally-packe…
Plate tectonics convectively cools the Earth at present. Debate remains in defining plate tectonics as a dynamic system. What is the primary resistor to plate motions: plates, mantle viscosity, some mixture of the two? Here I shed some light on this debate. First, I quantify the…
Since the Mesozoic, the west coast of North America has experienced near continuous right-lateral shear. Over this time, a series of exotic crustal terranes accreted to and translated along the expanding westward edge of the continent. In this dissertation, I use low-temperature…
