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...
The motivation to determine a viable alternative to petroleum based energy has risen in recent years due to increased greenhouse gas emissions, environmental pollution, and the fear of exhausting oil and natural gas reserves. Biodiesel derived from...
Vehicles--Environmental aspects; Traffic flow--Environmental aspects; Motor vehicles--Motors--Exhaust gas
The purpose of this dissertation is to develop a methodology to estimate the temporal Environmental Traffic Capacity (ETC) for urban streets. The approach constitutes the main procedure of ETC calculation and an experimental process of developing...
Accelerated life testing; Reliability (Engineering); Service life (Engineering)
This dissertation is focused on finding lower confidence limits for the reliability of systems consisting of Wei bull components when the reliability demonstration testing (RDT) is conducted with zero failures. The usual methods for the parameter...
Missing data is very common in survey research. However, currently few guidelines exist with regard to the diagnosis and remedy to missing data in survey research. The goal of this thesis was to investigate properties and effects of three selected...
The research problem presented herein involved the
structural determination of several a,~-unsaturated acids
and esters. The solution to this problem was sought in the
nuclear magnetic resonance (n.m.r.) spectra of these compounds.
The n.m.r....
Drug delivery systems; Curcumin--Therapeutic use--Administration
Curcumin, a plant derived compound has shown significant potency against various chronic diseases like cancer in cell culture and animal studies. However, the introduction of this compound into clinical setting is limited by its poor oral...
The process of transition from high school to adult life is particularly important for students with mild disabilities because these students show a pattern of overwhelmingly low expectations and progress. Transition services, self-determination,...
Optimizing queries in a distributed database is quite difficult. This work proposes defining new generalized quantifiers which operate on sets rather than tuples. These quantifiers would allow for easier optimization in a horizontally distributed...
The separation of C02 from light gases is a very important environmental and energy issue. The state-of-the-art process for the purification of C02 uses amine adsorption, which is a complex, and costly. Membrane technology is far less expensive...
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...
Working class in motion pictures; Motion pictures--Great Britain
Britain was the first country to industrialize with the Industrial Revolution and therefore had the world's first industrial working class. In the 20th century, the traditional British working class went through many social and political changes,...
Band directors--Attitudes; High school principals--Attitudes; Bands (Music)--Instruction and study
The purpose of this study was to survey secondary school administrator and band director perceptions regarding the implementation of Kentucky's Core Content for Assessment 4.1 (CCA 4.1) in Music in the band programs at their schools. Secondary...
The management of power and the optimization of systems generating and using power are critical technologies. A new architecture is developed to advance the current state of the art by providing an intelligent and autonomous solution for power...
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...
This dissertation presents a research whose objective is to design and develop an intrusion detection and response model for Mobile Ad hoc NETworks (MANET). Mobile ad hoc networks are infrastructure-free, pervasive and ubiquitous in nature, without...
Right-wing extremists--Germany; Political culture--Germany; Germany--Politics and government--1990-; Voting--Germany
Despite twenty years of political reunification Germany remains a politically, socially, and economically divided country. This has fuelled inequalities, which are used by extreme political parties to garner votes from citizens who have become...
Nanoparticles are a class of materials that exhibit unique physical and chemical properties compared to those of the same material at the bulk scale. One method of enhancing the thermal conductivity, and hence the heat transfer coefficient, of a...
Asian Americans--Cultural assimilation; Acculturation--United States; Sports spectators--United States; Consumer behavior--Social aspects--United States
According to the U.S. Census Bureau (2011), ethnic minority populations in the
U.S. constituted over one-third (approximately 126 million) of the total U.S. population
in 2010 (approximately 300.8 million) (U.S. Census Bureau, 2011). With such...
