The research in this dissertation describes a simple electrochemical approach for fabricating nanoscale (metal/metal) or molecular (metal/polymer or self assembled monolayer (SAM)/metal) junctions. The fabrication involves metal deposition on one...
The future of renewable energy technologies involves overcoming difficulties
with the creation of new materials. The use of nanotechnology has allowed for
inexpensive materials to achieve very interesting physical and electronic properties....
Computational grids are some of the largest computer systems in existence today. Unfortunately they are also, in many cases, the least reliable. This research examines the use of redundancy with permutation as a method of improving reliability in...
Medical appointments and schedules; Simulation methods
Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
From a computerized image analysis prospective, early diagnosis of lung cancer involves detection of doubtful nodules and classification into different pathologies. The detection stage involves a detection approach, usually by template matching,...
Data libraries--Security measures; Computer networks--Security measures; Information storage and retrieval systems; Digital preservation
Data centers (DC) are the core of the national cyber infrastructure. With the incredible growth of critical data volumes in financial institutions, government organizations, and global companies, data centers are becoming larger and more...
This dissertation is a participatory action research project with adults with mental retardation who reside in Louisville, Kentucky. It explores some of the history and ideologies that frequently have hindered persons with mental retardation from...
To manage large image databases, Content-Based Image Retrieval (CBIR) emerged as a new research subject. CBIR involves the development of automated methods to use visual features in searching and retrieving. Unfortunately, the performance of most...
This dissertation focuses on the mechanisms and implications of perceptual learning of binocular interactions. Perceptual learning is an important means of adapting to the changing environment, demonstrating the possibility of neural plasticity in...
In this work, micro fabrication techniques are explored not only to simplify the production of complex lab on-a-chip devices (LOC), but also micro fabrication will be utilized to create intelligent design features that will enhance an...
More than 50% of the total energy produced is typically rejected in the form of waste heat from various processes. The grand challenge is that most of this waste heat is released at temperatures much lower than 1000 C, which makes it difficult to...
Computer-assisted instruction; Three-dimensional imaging; Neuroanatomy--Study and teaching (Higher)
Visualizations in the form of computer-based learning environments are highly
encouraged in science education, especially for teaching spatial material. Some spatial
material, such as sectional neuroanatomy, is very challenging to learn. It...
No current microfabrication technique exists for producing room-temperature, high-precision, point-to-point polymer nanofibers in three dimensions. Producing rounded structures in a third dimension is particularly difficult to accomplish with...
III-nitrides (InN, GaN, AlN) are some of the most promising materials for making blue light emitting diodes (LED), blue laser diodes (LD) and high power, high temperature field effect transistors (FET). Current techniques produce GaN films with...
Enzymatic hydrolysis is the most common method of producing fermentable sugars from lignocellulosic biomass. Limitations to this step include the high cost of enzymes, and the time required to process the biomass. To increase the throughput and...
Corpus callosum; Diagnostic imaging; Autism--Diagnosis
Early detection of human disease in today’s society can have an enormous impact
on the severity of the disease that is manifested. Disease such as Autism and Dyslexia,
which have no current cure or proven mechanism as to how they develop, can...
4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are highly reactive á,â-unsaturated aldehydes. 4-HNE and acrolein are generated in vivo as products of lipid peroxidation. These aldehydes are implicated in the onset of several diseases...
Contamination can be very difficult to remove from water. Once this water seeps into the ground, the difficulty grows exponentially. The Paducah Gaseous Diffusion Plant, located in Paducah, Kentucky, has contaminated the groundwater. The...
