2015 marks the 50th anniversary of Moore's law, which has described the exponential progress in semiconductor patterning technologies, enabling creation of smaller circuitry features at greater densities. These continued hardware developments, economically mass manufactured, have made possible...
The present study has focused on the effects of Powdered Activated Carbon (PAC) in fly ash on the air-entraining admixture demand and consequent properties of concrete. An extensive laboratory test program was completed during this investigation. Three series of mixes were designed to evaluate...
The analysis of wide-angle cellular light scattering patterns is a challenging problem. Small changes to the organization, orientation, shape, and optical properties of scatterers and scattering populations can significantly alter their complex two-dimensional scattering signatures. Because of...
Data based abnormality detection is a growing research field focussed on extracting information from feature rich data. They are considered to be non-intrusive and non-destructive in nature which gives them a clear advantage over conventional methods. In this study, we explore different streams...
High-dimensional biological data have been increasingly made available for tackling complex health problems. As with any Big Data opportunities, this has led to methodological challenges for extracting relevant information from such data, particularly in settings where biologically-sensible and...
Functional Magnetic Resonance Imaging (fMRI) measures the dynamic activity of each voxel of a brain. This dissertation addresses the challenge of learning a diagnostic classifier that uses a subject’s fMRI data to distinguish subjects with neuropsychiatric disorders from healthy controls. fMRI...
Estimation of relative transport properties of fuel cell and electrolyzer transport layers by pore network and continuum based direct simulationsDownload
Improvements in the imaging techniques have enabled the capturing of images with high resolution, thereby permitting the reconstruction of complex porous media that can be analyzed by computer simulations. The two most popular methods for numerically analyzing transport in porous media are pore...
Chrome carbide samples prepared using submerged arc welding procedures were subjected to physical abrasion testing in a modified machine similar to the ASTM G65 standard, in an investigation of media particle shape contribution to abrasive wear. The primary intent of this study was to determine...
Image processing and analysis has been used in the sciences since before the advent of the personal computer, beginning as early as the 1920s (Gonzalez & Woods, 2002, p. 3-4). The need to improve image quality spurred the beginnings of scientific image processing, in which images are prepared...
