Pattern recognition systems; Cluster analysis; Data mining
Despite the large number of existing clustering methods, clustering remains a challenging task especially when the structure of the data does not correspond to easily separable categories, and when clusters vary in size, density and shape. Existing...
Clustered longitudinal data is often collected as repeated measurements on subjects over time arising in the clusters. Examples include longitudinal community intervention studies, or family studies with repeated measures on each member. Meanwhile,...
In this dissertation research, we aim to solve problems of two types of survival data, clustered survival data with potentially informative cluster size and sojourn time data. The methods for these two types of data are different. However, both...
The advent of larger storage spaces, affordable digital capturing devices, and an ever growing online community dedicated to sharing images has created a great need for efficient analysis methods. In fact, analyzing images for the purpose of...
Swarm Intelligence (SI) techniques were inspired by bee swarms, ant colonies, and most
recently, bird flocks. Flock-based Swarm Intelligence (FSI) has several unique features, namely
decentralized control, collaborative learning, high exploration...
How do words represent emotional states, and how closely are they clustered to an actual emotion? Opinions vary as to how many emotions there are, and whether (or which) emotions are basic. Generally, many agree that basic emotions include fear,...
Images, Photographic--Databases; Image processing--Digital techniques; Data mining; Cluster analysis
The performance of content-based image retrieval systems has proved to be inherently constrained by the used low level features, and cannot give satisfactory results when the user's high level concepts cannot be expressed by low level features. In...
Pattern perception--Data processing; Pattern recognition systems; Land mines--Detection; Data mining
For complex detection and classification problems, involving data with large intra-class variations and noisy inputs, no single source of information can provide a satisfactory solution. As a result, combination of multiple classifiers is playing...
Data mining; Lungs--Cancer; Outcome assessment (Medical care)
Lung cancer is the leading cause of cancer death in the United States and the world, with more than 1.3 million deaths worldwide per year. However, because of a lack of effective tools to diagnose Lung Cancer, more than half of all cases are...
Recent advances in high throughput methodologies offer researchers the ability to understand complex systems via high dimensional and multi-relational data. One example is the realm of molecular biology where disparate data (such as gene sequence,...
The purpose of this research study is to examine the use of time series forecasting and text mining to investigate the prescription of antibiotics. The specific objective is to examine the relationship between the total payments, private insurance...
Pattern recognition systems; Land mines--Detection; Pattern perception--Data processing; Data mining
Traditional machine learning and pattern recognition systems use a feature descriptor to describe the sensor data and a particular classifier (also called "expert" or "learner") to determine the true class of a given pattern....
In blood coagulation, the serine protease thrombin is a multifaceted enzyme that interacts with multiple proteins. Thrombin utilizes two anion binding exosites (ABE-I and II) to supplement binding to fibrinogen and to the platelet receptor GpIbα,...
Nerves--Regeneration; Spinal cord--Wounds and injuries--Treatment
These studies set out to identify strategies to rescue and repair the adult nervous system. First, we investigated the role of ciliary neurotrophic factor (CNTF) in 5HT1A receptor-induced neurogenesis in the rodent brain. Systemic treatment with an...
Energy independence requires that the nation reduce its dependence on foreign oil imports. This can be achieved through electrification of transportation vehicles if proper battery technology can be developed. In addition, the renewable energy...

Louisville & Nashville Railroad grade crossing at Baxter Avenue, Louisville, Kentucky. Close-up of an engine on a bridge (photographed from behind) and the profile of a man on the bridge in the sunlight, wearing a suit and hat. Another man is...
Buildings; Military facilities; Armories; Fires; Kentucky. National Guard
Close-up of fire at Arsenal building of the (Frankfort) Kentucky National Guard. The arsenal caught on fire during the night of June 30, 1933, after an explosion on the second floor. A cluster of men spray a fire hose at the smoke coming from the...
Aerial view of OFC Distillery, Frankfort, Kentucky. View of buildings at center, farmland behind and river in front. There is a cluster of about seven buildings with dark roofs. There is also a water tower, amid trees. Stamp: "Bowman-Park Aero...
