The Louisville Leader was an African-American newspaper published from 1917 to 1950 by I. Willis Cole in Louisville, Kentucky. This issue says Vol. 28. No. 48. but is actually Vol. 28. No. 49. This issue is four pages.
Wind energy provides an attractive power source as an alternative to fossil fuels because it is abundant, clean, and produces no harmful emissions. To extract more energy from the wind we need to increase the wind turbine size. However, the...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
Cumberland Falls State Park (Ky.); Historic preservation--Kentucky
This thesis is an examination of Louisville Times editor Tom Wallace's fight to prevent the construction of a hydroelectric dam at Cumberland Falls, Kentucky between 1926 and 1931. By mining Wallace's recently cataloged personal papers, this study...
The management of power and the optimization of systems generating and using power are critical technologies. A new architecture is developed to advance the current state of the art by providing an intelligent and autonomous solution for power...
Brief Overview of the Problem: The Environmental Protection Agency (EPA), a government funded agency, provides both legislative and judicial powers for emissions monitoring in the United States. The agency crafts laws based on self-made regulations...
The purpose of this research is to understand how the process parameters surrounding the Direct Metal Deposition (DMD) process affect the properties of the deposition. The powder used in this research is pre-alloyed titanium powder (Ti-6Al-4V),...
In July 1995, National Science Foundation Award # 9551869 funded the development of a new inter-disciplinary microfabrication course under the primary leadership of Dr. Kevin Walsh at the University of Louisville. Along with this award, the...
Preventive maintenance is a broad term that encompasses a set of activities aimed at improving the overall reliability and availability of a system. Preventive maintenance involves a basic trade-off between the costs of conducting...
Protective coatings; Microelectromechanical systems
PARYLENE (poly-para-xylylene) is mostly used as a conformal protective polymer pin-hole free coating material to uniformly protect any component configuration on diverse substrates. This thesis describes in detail how the unique properties of...

Wind energy conversion systems; Wind power--Technological innovations; Wind power--Research
This thesis proposes a new Maximum Power Point Tracking (MPPT) algorithm employed in Wind Energy Conversion Systems (WECS). One of the major issues discussed in the literature concerning HCS is its inefficiency in detecting the peak power when...
Current wind power technology is not economically feasible throughout most of the United States due to low average wind speeds. A design for a small-scale wind concentrator device suitable for use in areas of low wind velocity was tested using...
Vertical axis wind turbines (VAWTs) are devices to convert wind energy into electricity. Unlike horizontal axis wind turbines (HAWT) where the main rotor shaft is set horizontally, VAWTs use vertical rotor shaft. Unlike HAWTs, VAWTs can be...
Wind power has the potential to provide access to electricity to areas lacking the resources to create industrial power plants, as well as supplement residential energy supplies. The low resource investment and ease of installation make it ideal...
