Lower bounds for the variance of uniformly minimum variance unbiased estimators
… estimators. The lower bounds of Cramer and Rao, Bhattacharyya, Hammersley, Chapman and Robbins, and Kiefer were derived and discussed. Each was compared with the other, showing their relative merits and shortcomings. Of the lower bounds considered all are greater than or equal to the Cramer-Rao …

Feature selection for cancer classification using microarray gene expression data
… data. For two-group classification problem, the Bhattacharyya distance is proposed to measure the dissimilarity in gene expression levels between the two groups. For any particular gene, we calculate the Bhattacharrya distance between the two groups based on the expression levels of that …

Robust Unconstrained Face Detection and Lip Localization Using Gabor Filters
… as a visual front end to AVASR systems. A novel Bhattacharyya-based face detection algorithm is used to compare candidate regions of interest with a unique illumination-dependent face model probability distribution function approximation. Following face detection, a lip-specific Gabor …

Arithmetic regularity lemmas and applications
… of the induced arithmetic removal lemma of Bhattacharyya, Fischer, and Lovett [6] for translation-invariant arithmetic patterns, extending it to partition-regular patterns of complexity 1; this also strengthens the result of Fox, Tidor and Zhao [16] for general complexity-1 patterns. Chapter …

Machine Learning-Driven Corrosion Detection and Classification in Pipelines
… Decomposition with Adaptive Noise (CEEMDAN) and Bhattacharyya Variance Distance (BVD) algorithms to enhance signal quality. Key features indicative of pipeline condition were extracted and subjected to clustering analysis using the K-means algorithm, categorizing the data into distinct groups …

Hearing health care in the United States: A multi-scale spatial & political economic analysis of health care policy and access to audiology services
… compared with the general population (Jung and Bhattacharyya, 2012). Therefore, this project examines audiologists, focusing on how their scope of practice and autonomy as professionals are constrained by health policy at the federal and state levels and the broader political economy of …

Transform texture classification
… by several orders of magnitude. The statistical Bhattacharyya distance measure is then used to rank dominant features according to their discrimination power. Experimental results of applying the new algorithm to the three transform matrix classes show a strong increase in performance by texture …

Synthetic sensing systems in Saccharomyces cerevisiae
The yeast Saccharomyces cerevisiae is a major chemical production platform in the biotechnological industry. It is also increasingly being used as a whole cell biosensor. One method of developing such whole cell biosensors in yeast is by exploiting its mating pathway, which is normally induced by …

Using palm-mat geotextiles for soil conservation on arable loamy sands in the United Kingdom
To date, most studies on the effectiveness of geotextiles on soil erosion rates were conducted in laboratory experiments for <1 h. Hence, at Hilton, East Shropshire, UK, this study investigated the effectiveness of palm-mat geotextiles (Borassus and Buriti mats) in reducing rainsplash erosion, …

Satellite imagery evaluation of soil moisture variability in north-east part of Ganges Basin, India
Soil moisture variability across four river systems in Ganges Basin, from the Tista and Kosi Rivers in the east to the Gandak and Ghaghra-Rapti Rivers in the west, was assessed using Landsat TM Band 6 imagery dating from 1999-2003. The Band 6 thermal channel of Landsat is sensitive to soil …

Aspects of holography in Lorentz-violating gravity
<p>The study of black hole thermodynamics has provided deep insights into the nature of quantum gravity. In particular, it is almost universally accepted nowadays that 'quantum gravity is holographic', so that the maximum amount of information allowed in a given region of spacetime is proportional …

HOW CONTEXT MATTERS IN DIGITAL LIBRARY USE
<p>This research investigates how organizational context contributes to the use of digital libraries, an ICT-enabled information infrastructure. Traditionally digital-library use is measured with the help of statistical analysis of download and other related data, but statistics alone have limited …

Three Essays on the Impact of Medicaid Expansion on Cancer Care and Mis-Measured Self-Reports of Cancer Screening Status
The dissertation consists of three essays attempting to assess the impact of expanded health insurance policy on cancer care continuum and measure the unbiased program effects after taking care of mis-measured cancer screening self-reports. The first essay examines the impact of the Affordable Care …

NMR Characterization of Novel Materials for Battery Electrolyte Applications
<p>The extensive application of renewable and non-renewable energy storage devices in commercial products and services and the global warming have created significant motivations to accelerate research in battery technology. In addition, the risk factors generated by the high heat generation and …

Escape of hydrogen from the exosphere of Mars
After decades of exploration, the martian neutral hydrogen exosphere has remained poorly characterized. The first measurements of this layer by Mariner 6 and 7 revealed it to be optically thick in Lyman α emission, along with a characteristic temperature that was higher than the majority of the …

Environmental Risk Choices: An Empirical Analysis of EPA's Pesticide Rules
The major policy implications are that given the importance of the participation variables and risk estimates, greater resources and attention need to be focussed on better managing these two aspects of the rule-making process. Results also point to the need for focussing attention on improved risk …
