An investigation was made into the relative costs of excavation retention by two systems: conventional soldier pile-wale-tieback support, and support by soil nailing. The investigation included design of excavation supports by the two...
In the electronic and microfabrication industry, die separation is one of the most critical steps in producing an undamaged, stand-alone micro-scale device. For silicon based devices, it is the predominant step governing resistance to die failure...
Mathematics--Study and teaching (Middle school)--Ohio; Educational tests and measurements--Ohio
Classroom tests from nine eighth-grade mathematics teachers were collected from the 2003-04 and 2005-06 school years. These years represent one school year prior to the eighth-grade Ohio Achievement Test (OAT) in mathematics being implemented and...
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...
A significant amount of effort has been put in developing tools to interpret Ground Penetrating Radar signals obtained during surveys. Currently, skilled and experienced users do most of GPR image interpretation. They use experience in deciphering...
A potential source of fine grained suspended sediments in a stream system is the
upper hillslopes of the drainage. Quantifying the sediment produced and transported to a
stream from these hillslopes is challenging because of the complex nature of...
Computer vision; Pattern recognition systems; Human face recognition (Computer science)
Humans have the uncanny ability to perceive the world in three dimensions (3D), otherwise known as depth perception. The amazing thing about this ability to determine distances is that it depends only on a simple two-dimensional (2D) image in the...
Human-computer interaction; Computer vision; Human-machine systems; Nonverbal communication
Hand gesture recognition (HGR) is an important research topic because some
situations require silent communication with sign languages. Computational HGR
systems assist silent communication, and help people learn a sign language.
In this thesis. a...
Water treatment facilities strive to provide potable drinking water to the community which they service. The most common way of insuring drinkable water that is free of pathogens is water chlorination, but this can lead to the production of...
In 2003, Wilson Creek running through Bernheim Arboretum and Research Forest in central Kentucky was restored to its original winding path through a valley field. Early 20th century settlers had previously redirected this creek to run a straight...
In recent years, a number of computational and statistical problems for identifying SNP-SNP interactions in high dimensional survival data have been studied, and several data mining approaches have been proposed. However, the relative performance...
A new procedure has been developed for determining
the location of the source of certain EEG discharges
given the measured surface potentials. The
source is modeled as a single current dipole with arbitrary
position and orientation, while the head...
Aims. The primary aim of this randomized, blinded, controlled clinical trial was to compare the percent root coverage obtained using acellular dermal matrix allograft and connective tissue graft using the coronally positioned tunnel technique 4...
The following thesis examines the relationship between site geology and ground motion amplification for medium sized earthquake events in the Ohio Valley area. This thesis also includes a Rapid Screening Guide that can be used to estimate...
Indians of North America--Kentucky--Bullitt County--Antiquities; Excavations (Archaeology)--Kentucky--Ashworth Rockshelter site; Ashworth Rockshelter site (Ky.)
Reinvestigation of a National Register property, the Ashworth Rockshelter (15BU236), northeast of Shepardsville, Bullitt Co., Kentucky, revealed stratified Early Archaic through Mississippian components (ca. 7900 B.C.-1500 A.D.). Primary occupation...
Aims. The primary aim of this randomized, blinded, controlled clinical trial was to compare the percent root coverage obtained using a coronally positioned tunnel surgery plus an acellular dermal matrix allograft (ADM) with single tooth sling...
High dynamic range imaging involves imaging at a bit depth higher than the typical 8-12 bits offered by standard video equipment. We propose a method of imaging a scene at high dynamic range, 14+ bits, to detect motion correlated with changes in...
Calculators--Study and teaching (Middle school); Functions--Study and teaching (Middle school); Algebra--Graphic methods; Computer-assisted instruction
The purpose of this study was to determine the effect of TI-Nspire graphing calculator use on student achievement and on teacher behavior variables of planning, teaching, and assessing. This study investigated the teaching of functions by teachers...
This thesis and exhibition examine the connection between neurobiology and Op Art. Neurobiological explanations of Op Art's effects are explored as a means to offer insight into the processes of the human mind and eye, and to provide explanations...
Stream riparian zones are ecotones between terrestrial and aquatic environments. Studying these areas in urban environments is important since they lie adjacent to stream water supplies. I conducted a study of riparian woody and groundcover...
