The purpose of this study was to investigate the home remodeling
being done during a period of varying economic conditions. A
population of owner-occupants who had purchased building permits to
spend $100 or more remodeling between 1965 - 1970 was collected
from the files of the Building Inspector's Office, Department...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
OBJECTIVES: Secondary caries is the most common reason for composite restoration replacement and usually forms between dentin and the filling. The objective of this study was to investigate the combined effect of cyclic loading and bacterial exposure on bacterial penetration into gaps at the interface between dentin and resin composite...
Missing data can lead to biased and inefficient estimation if the missing mechanism is not taken into account in the analysis. In this dissertation we propose two estimators that, under fairly general conditions, are asymptotically unbiased. The first proposed estimator assume the data are missing at random (MAR) and does...
To facilitate the design of Natural and Nature-Based Features (NNBF) for flood protection, this thesis expands an existing engineering design methodology to NNBF systems. The existing approach is a Level III reliability method for the performance-based design of traditional coastal engineering systems. The expanded methodology incorporates uncertainties inherent to both...
Radiochromic film dosimetry offers many advantages over standard film that requires wet chemical processing. Radiochromic film offers: a permanent color change upon irradiation; high spatial resolution; a response that is independent of energy, particle type, and angle of incidence; near tissue equivalence; and a wide dosimetric range. However, there are...
Qualitative data analysis (QDA) is a time consuming and, potentially unreliable research activity. In qualitative research, a number of tasks must be repeated for every new research case, even if each case is closely related or is in the same area of study.
Existing QDA applications provide users with a...
Digital Human Modeling (DHM) is a computational design tool that allows designers to use virtual prototypes of design for exploring ergonomics requirements. DHM brings in the advantage of reducing the time and finances committed to building the physical prototypes as well as minimizing the efforts put on performing human subject...
Wavelet analysis is an analytical and modeling tool for optimizing sampling efficiency and accuracy, particularly in the context of designing long-term, large-scale monitoring plans. As a pattern analysis method that accommodates and preserves non-stationarity, wavelet analysis provides novel visualization and analytical capabilities for increased insight into interactions between multi-scalar heterogeneous...
Nanoparticles (NPs), defined by their size (1-100 nm), are increasingly incorporated into commercial and industrial products due to their high surface area and unique properties. They can be designed for specific applications by manipulating composition, size, shape, and surface functionalization. As NP production and complexity increases, there is a need...
