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...
This work examines our perception of distance within "action space" (about 2m ~ 30m), an ability that is important for various actions. Two general problems are addressed: what information can be used to judge distance accurately and how...
This dissertation deals with various imidazole compounds with emphasis on hydrogen bond interactions and weaker intermolecular forces. New amide functionalized polyimidazole metal binding pockets are able to form intramolecular six-membered...
Background: Light cured composite resin can be time consuming for bonding orthodontic brackets. A new Blue light diode laser may reduce curing times for composite resins. Hypothesis: The laser will achieve similar bond strengths in half the time...
Nonparametric statistics; Estimation theory; Distribution (Probability theory)
Multistate models are a type of multi-variate survival data which provide a framework for describing a complex system where individuals transition through a series of distinct states. This research focuses on nonparametric inference for general...
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...
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...
Nitrile hydratase (NHase) is a metalloenzyme that contains a non-heme iron (III)
or non-corin cobalt (III) in a non-redox active role. NHase is used as biocatalyst in the
industry for the hydrolysis of nitriles to arnides. The trivalent metal ions...
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...
The Faroe Islands are a small archipelago in the North Atlantic. With a current population of approximately 49,000 individuals and evidence of high levels of genetic drift, the Faroese are thought to have remained highly homogeneous since their...
The revolution in information technology and the explosion in the use of computing devices in people's everyday activities has forever changed the perspective of the data mining and machine learning fields. The enormous amounts of easily...
The main purpose of this research is to make a comparative study of the physical mechanisms related to highway noise barrier insertion loss and to evaluate and improve the accuracy of insertion loss of FHWA Traffic Noise Model (TNM) 2.5 comparedw...
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...
Metastasis is a complex process requiring directed migration of metastatic cells to favorable microenvironments. Increased CXCR4 expression has been implicated in more invasive, aggressive and metastatic tumor phenotypes and poor patient survival...
Human being can easily acquire information by showing the object than reading the description of it. Our brain stores images that the eyes are seeing and by the brain mapping, people can analyze information by imagination in the brain. This is the...
Objective . To compare the in vitro reliability and accuracy of linear measurements between cephalometric landmarks on CBCT 3D images with varying basis projection images to direct measurements on human skulls. Methods . Sixteen linear dimensions...
All terrain vehicles--Automatic control; Motor vehicles--Automatic control; Intelligent control systems
When tracked vehicles traverse terrain such as sand, soil, or even concrete,
they may encounter a variance in density or viscosity of the medium that the
vehicle is traveling along. When this happens, one track begins to move faster or
slower...
This study focuses on the variation in structural response to synthetic ground motions derived from the latest attenuation models developed for the Central Eastern United States (CEUS) and used by the USGS to develop the latest edition (2008) of...
Periodontitis--Age factors; Natural immunity; Age factors in disease
Age-related alterations in innate immunity are poorly understood. The identification of those mechanisms, which are dysfunctional in old age, will shed light on potential therapeutic strategies for chronic inflammatory diseases prevalent in the...
Representing the complex data in a concise and accurate way is a special stage in data mining methodology. Redundant and noisy data affects generalization power of any classification algorithm, undermines the results of any clustering algorithm and...
