The area of total coloring is a more recent and less studied area than vertex and edge coloring, but recently, some attention has been given to the Total Coloring Conjecture, which states that each graph's total chromatic number xT is no greater...
Various vision tasks are usually confronted by appearance variations due to changes of illumination. For instance, in a recognition system, it has been shown that the variability in human face appearance is owed to changes to lighting conditions...

Environmental or air quality impacts of Intelligent Transportation Systems (ITS)
are very difficult to measure. Some researchers have attempted to quantify the effects of
individual ITS application on emissions; yet, the effects of ITS as a whole...

Gold nanoparticles (GNPs) have shown beneficial properties for biomedical use, e.g., their non-toxic nature and surface properties for easy modification. Upon receiving light, they generate a strong surface plasmon field, which can alter the...
Planar fiber-optic chips (FOC) take advantage of the evanescent field effects of side-polished fibers, exhibiting usefulness in fluorescence, absorbance, electrochemical investigations, and as presented here Raman spectroscopy. The fabrication of...
The Combinatorial Nullstellensatz can be used to solve certain problems in combinatorics. However, one of the major complications in using the Combinatorial Nullstellensatz is ensuring that there exists a nonzero monomial. This dissertation looks...
Microfabricated planar solar cells with an active solar collection area of 0.04cm2 were fabricated on n-type silicon wafers to test the viability of sputtered amorphous thin film photovoltaics for potential use in amorphous multijunction cells or...
Outerplanar graphs are planar graphs that have a plane embedding in which each vertex lies on the boundary of the exterior region. An outerplanar graph is maximal outerplanar if the graph obtained by adding an edge is not outerplanar. Maximal...
Understanding the nucleation and early stage growth of crystals from the vapor phase is important for realizing large-area single-crystal quality films, controlled synthesis of nanocrystals, and the possible discovery of new phases of materials....
Older people--Mental health; Rural health; Urban health
Depression is one of the most prevalent psychiatric conditions experienced by older adults and represents a major public health concern. Rural/urban residence may affect the prevalence of depression as rural older adults differ from their urban...
This thesis lays the groundwork for creation of a graduate-level computer forensics course. It begins with an introduction explaining how computing has invaded modern life and explains what computer forensics is and its necessity. The thesis then...
We study a sensor location problem that minimizes the total number of sensors to install at road intersections in a transportation network so that the traffic flows on the entire network are uniquely determined. We employ the concepts of hidden...
Residential buildings account for a large portion of total energy consumption in the United States. Residential energy usage can be dramatically reduced by improving the efficiency of building envelope systems. One such method is to incorporate...
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...
Understanding of the band structure of the new nano materials is essential to have a deeper insight into their optical and electrical properties. Along with the existing techniques used for characterization of nano-materials, it is also important...
QSOs, providing distant, luminous sources of radiation, provide a means to detect gas by absorption in the interstellar and intergalactic medium. Of particular interest to astronomers studying metal line systems in lines of sight to QSOs are the...

Large-scale emergencies caused by earthquake, tornado, pandemic flu, terrorism attacks and so on can wreak havoc to communities. In order to mitigate the impact of the events, emergency stockpiles of food, water, medicine and other materials have...
Remote terminal units (RTUs) are perimeter supervisory control and data acquisition (SCADA) devices that measure and control actual physical devices. Cyber security was largely ignored in SCADA for many years, and the cyber security issues that now...
This dissertation explores how presidential inaugural speeches reflect the overarching mindset of the government, and how, in the postmodern era, this mindset manifests the same sort of African American erasure that has existed since Middle...
