A blinded observational cross-sectional in vitro study was conducted to compare the diagnostic accuracy of observers viewing images made using cone beam computerized tomography (CBCT), panoramic radiography and linear tomography. The sample...
A combination of three techniques – high resolution micro computed tomography (micro CT) scanning, Archimedes-based volume fraction measurement and serial sectioning or milling – were used to determine the volume fraction, trabecular thickness,...
A common problem faced by most organizations in today's world is one of worker-task assignments. Assigning a large number of complex tasks to workers at various training levels can be a complicated process which has the potential to cost or to save...
A common research interest in medical, biological, and engineering research is determining whether certain independent variables are correlated with the survival or failure times. Standard statistical techniques cannot usually be applied for...
A connected matching in a graph is a set of disjoint edges such that, for any pair of these edges, there is another edge of the graph incident to both of them. This dissertation investigates two problems related to finding large connected matchings...
Medical policy--Kentucky--Louisville; Political planning--Kentucky--Louisville; Cities and towns--Growth--Kentucky--Louisville
A disciplined-configurative case study design was carried out to explore whether a growth machine exists and shapes local healthcare policy in Louisville. A historical analysis first explored whether a growth machine existed in Louisville in the...
A hyper basis function network (HyperBF) is a generalized radial basis function network (RBF) where the activation function is a radial function of a weighted distance. The local weighting of the distance accounts for the variation in local scaling...
A k-term quasi-progression of diameter d is a sequence {Xl,... ,xk} for which there exists a positive integer l such that l < Xi-Xi-1 < l+d, for all i = 2, ... ,k. Quasi-progressions may be thought of as arithmetic progressions with a certain...
Medical records--Data processing; Data mining; Databases--Design
A major problem with integrating information from multiple databases is that the same data objects can exist in inconsistent data formats across databases and a variety of attribute variations, making it difficult to identify matching objects using...
Coronary heart disease--Treatment--Cost effectiveness; Angioplasty; Medical laws and legislation--Kentucky
A myocardial infarction (MI) occurs when blood supply to the heart is cut off by a blockage in one of the coronary arteries. Most hospitals treat a patient with thrombolysis or a percutaneous coronary intervention (PC I). The latter has been...
Football teams--Ratings and rankings; Ranking and selection (Statistics)
A new method to rank football teams with the concepts associated with the Analytic Hierarchy Process(AHP) and Graph theory is developed in this thesis. A set of games is interpreted as a graph, in which every vertex represents a team, and every...
A new procedure has been developed for determining
the location of the source of certain EEG discharges
given the measured surface potentials. The
source is modeled as a single current dipole with arbitrary
position and orientation, while the head...
A projected high penetration of battery electric vehicles (BEV s) in the market will introduce an additional load in the electricity grid. Furthermore, uncontrolled BEV charging from residential users will exacerbate the existing peak load during...
Emergency medicine--Diagnosis; Emergency medical services
A retrospective study involving the secondary analysis of public health surveillance records was undertaken to characterize the reliability and validity of an EMS dispatch data-based scheme for assigning emergency patients to surveillance syndromes...
A significant amount of effort has been put in developing tools to interpret Ground Penetrating Radar signals obtained during surveys. Currently, skilled and experienced users do most of GPR image interpretation. They use experience in deciphering...
A system for analysis of the traffic flow on public streets and highways through the use of Floating Car Data (FCD) relies completely on the number of simultaneously contributing vehicles, a fact that is no barrier for the phases of conception and...
A wireless sensor network consists of a large number of low-power nodes equipped with wireless radio. For two nodes not in mutual transmission range, message exchanges need to be relayed through a series of intermediate nodes, which is a process...
Activity-based rehabilitation is important for clinically treating spinal cord injury (SCI). Advances in SCI research are dependent on quality animal models, which rely on our ability to detect functional differences in animals following injury....
Web search engines; Automatic abstracting; Graph theory--Data processing
After a user types in a search query on a major search engine, they are presented with a number of search results. Each search result is made up of a title, brief text summary and a URL. It is then the user's job to select documents for...
An ensemble consists of a set of individual predictors whose predictions are combined. Generally, different classification and regression models tend to work well for different types of data and also, it is usually not know which algorithm will be...
