The general public is being exposed to robots more often every day. This thesis focused on the advancement of research by analyzing whether or not the type of information provided by a robot determined the level of trust humans have for a robot. A study was conducted where the participants were asked to answer two different types of questions: mathematical/logical and ethical/social. The participants were divided into two different conditions: controlled and misinformed. A humanoid robot provided its own spoken answer after the participants said their answers. The participants then had the chance to select whose answers they would like to keep. During the misinformed condition, there were times when the robot purposely gave incorrect answers. The results of the study support the hypothesis that the participants were more likely to select the robot’s answers when the question type was mathematical/logical, whether the robot provided a correct or incorrect response.

Cementitious materials obtained from different sources, while evaluated and classified by the same methods and criteria, often produce concrete with compressive strength variance despite other inputs remaining constant. The focus of this thesis was to enumerate and illustrate the possible compressive strength variation when cementitious material sources are interchanged, and investigate the influence that aggregate can have on this variation. This was accomplished by compiling and analyzing compressive strength data from previous research initiatives, and concluded that coefficient of variation (COV) and range values at the 14-, 28-, and 56-day timeframes due to a cement source change varied between 15.3% and 18.1% and 1,988 psi and 2,728 psi in concrete, and 16.1% and 22.9% and 3,406 psi and 5,884 psi in paste or mortar. Concrete that included supplementary cementitious material (SCM) displayed up to 4.1% higher COV values versus non-SCM mixtures, and specific aggregate/cementitious material combinations influenced compressive strength variability.

Identification of source code authorship can be a useful tool in the areas of security and forensic investigation by helping to create corroborating evidence that may send a suspected cyber terrorist, hacker, or malicious code writer to jail. When applied to academia, it can also prove a useful tool for professors who suspect students of academic dishonesty, plagiarism, or modification of source code related to programming assignments. The purpose of this dissertation is to determine whether or not cross-entropy approaches to source code authorship analysis will succeed in predicting the correct author of a given piece of source code. If so, this work will try to identify factors that affect the accuracy of the algorithm, how programmer experience determines accuracy, and whether a cross-entropy approach performs better than some known source code authorship approaches. The approach taken in the research effort will manufacture a corpus of source code writings from various authors based on the same system descriptions and varying system descriptions, from which benchmarks of different approaches can be measured.

A laser ion source was investigated for a laser produced spatially bound plasma and the production of cluster ions. The design of a unique geometry for the target was fabricated to have a hollow cylindrical structure where the plasma is ignited inside the narrow volume. The study clarified the difference in the plasma dynamics of the laser ion source operation using the hollow cylinder target as the plasma was allowed to interact with the target surface. The proposed scheme, aiming to produce a low plasma temperature condition, was observed to the increase the probability for agglomeration and generated cluster ions. / 博士(工学) / Doctor of Philosophy in Engineering / 同志社大学 / Doshisha University

This study investigated the pollutant removal performance of a constructed wetland treating stormwater runoff from a residential townhome complex in Manassas, Virginia. The facility was constructed by retrofitting a dry detention basin to retain a permanent shallow pool and included additional temporary storage to detain roughly the first half inch of rainfall for approximately 24 hours. Vegetation was allowed to establish itself through volunteer colonization, rather than active planting of selected wetland species. Flow measurements showed substantially greater volume passing through the outlet than entering through the single gaged inlet. The extra volume (about 41% of the total) was attributed to ungaged overland flow which drained a wooded/grassy area adjacent to the site. Mass balance calculations employing the rational method with a runoff coefficient of 0.2 to estimate the flow from this area showed good agreement between long-term total estimated inflow and measured outflow. However, this method was not effective in accounting for the discrepancies between inlet and outlet volumes of individual storms. Thirty-three runoff events were monitored between April, 1996 and May, 1997. Because of greater flow volumes passing through the outlet, constituent mass calculations which ignored the overland contribution generally exhibited higher loads exiting than entering the facility. With the results from a limited number of grab samples representing concentrations in overland input, estimated efficiencies improved substantially, showing overall net removal for most constituents. Less than one year after being retrofitted, the basin showed signs of beginning to develop a diverse wetland flora. / Master of Science

The Upper Cretaceous (Maastrichtian) Belqa Group in Jordan consists predominantly of organic-rich carbonate mudrocks that represent excellent source rocks but are still immature to just entering the oil window. Therefore, they offer a unique opportunity to study lithology, source rock composition, and geochemistry prior to the onset of maturation and expulsion of hydrocarbons. Our study examines the lithological and geochemical characteristics of these high-quality source rocks. To define the lithofacies and analyze the heterogeneities, 23 samples were investigated for their composition and texture using optical microscopy, SEM/EDS, XRD, and XRF). Geochemistry analyses were based on total organic carbon (TOC), Rock-Eval pyrolysis, and vitrinite reflectance. Four lithofacies were defined in this study: Strongly bioturbated calcareous mudstone (LF1), Slightly laminated calcareous mudstone (LF2), Parallel laminated calcareous mudstone to wackestone (LF3), Fine to coarse silicified wackestone to packstone (LF4), all containing significant organic content (TOC varies from 6 to 20 wt.%) and Sulphur contents (1.3-4.7 wt.%). Kerogen types are predominantly II-S with high HI (Hydrogen Index) values of >700 mg HC/g TOC. XRD results show that the rocks are mainly composed of calcite (75% on average) and quartz (10% on average). Minor amounts of clay (< 7%), pyrite (up to 6%), gypsum (up to 4%), and dolomite (up to 3%) also exist. Our results evidenced the high heterogeneity in the lithofacies of the MCM formation samples. Despite the traditional interpretation of low-energy suspension settling, we demonstrated the presence of bottom currents during the deposition of the Upper Cretaceous source rocks in Jordan (ripples, rip-up mud, reworking material, and fossil-rich lenses) and insight into the bottom water conditions (anoxic and oxic). The integration of the data obtained through the different techniques used in this study, together with the unique characteristics of these source rocks, allowed the characterization of the geological and geochemical properties of the defined lithofacies associations in these immature, Upper Cretaceous source rocks. This, in turn, helped to better evaluate the occurrence and distribution of the different litho- and organic facies and estimate hydrocarbon source potential.

The beta dose distributions in red bone marrow equivalent material due to imbedded continuous sources were measured experimentally with ultra thin LiF thermoluminescent dosimeters near planar interfaces of cortical bone (CB) and red bone marrow (RBM), and RBM and air. It has been also investigated numerically by Cyltran, the Monte Carlo code. In the Monte Carlo approach, the dose enhancement ratio for a planar CB-RBM interface increases with electron energy and reaches a plateau at 0.50 MeV while the dose reduction ratio for a planar vacuum-RBM interface decreases to a steady value from 1.00 MeV onwards. With a semi-infinite source of 32P, dose enhancement ratios at 0-9, 79-88, and 157-166 mg/cm2 separations from a planar CB-RBM interface were measured to be 1.07±0.01, 1.03+0.03 and 0.99+0.03 respectively. The dose reduction ratios at these separations from a planar AIR-RBM interface were found to be 0.82±0.01, 0.94+0.03 and 0.97+0.03 respectively. Both the dose enhancement ratios and dose reduction ratios agree with the results calculated by the Monte Carlo approach within one standard deviation except for the dose reduction ratio at 0-9 mg/cm2 from the AIR-RBM interface. The experimental result in this case is about three standard deviations less than the Monte Carlo results. Using the same Monte Carlo code, the dose enhancement ratio at 0-20 micron separation from a planar CB-RBM interface due to a point or plane source of 0.50 MeV electrons at the interface reaches saturation at approximately 0.22 times the CSDA range of 0.5 MeV electron in CB for both plane and point source configurations. The saturation dose enhancement ratio for both configurations is 1.06±0.01. / Thesis / Master of Science (MS)

The Borexino solar neutrino detector is a real-time liquid scintillator detector designed to measure sub-MeV neutrinos. With its unprecedented level of radio-purity, Borexino is poised to provide the most precise measurements to-date of solar neutrino and geo-antineutrino fluxes. However, in order to reduce the systematic errors to sub-5% levels, the detector must be care- fully calibrated to understand, among other things, the position and energy reconstructions. To that end, the Virginia Tech component of the Borexino collaboration has constructed a system for deploying and locating calibration sources within the detector. The system was used in four separate calibration campaigns and deployed numerous sources in almost 300 locations throughout the detector. The data from the calibrations have already resulted in the reduction of several sources of systematic error by a factor of two or more. With the results from the calibration, the Borexino detector has entered a new era of low- energy, high-precision, neutrino detection. This work was supported by NSF Grant 0802114 / Ph. D.
