Autonomous Unmanned Ground Vehicle For Non-Destructive Testing Of Fiber Reinforced Polymer Bridge Decks, Anthony Scott Mercer
Graduate Theses, Dissertations, and Problem Reports
The objective of this research is to develop an Unmanned Ground Vehicle (UGV) that can autonomously gather data for analysis of FRP bridge decks. Both ground penetrating radar (GPR) and infrared thermography (IRT) have shown promise in the field of non-destructive detection of defects in FRP decks. Even though both technologies can be effective, they each have certain limitations. For example, GPR is sensitive to water-filled defects while IRT is more sensitive to air-filled defects. This thesis investigates the effectiveness of combining and automating the data acquisition for each technique. Since both IRT and GPR analysis are subjective in nature, …
Recognition Capacity Of Biometric-Based Systems, Francesco P. Nicolo
Recognition Capacity Of Biometric-Based Systems, Francesco P. Nicolo
Graduate Theses, Dissertations, and Problem Reports
Performance of biometrics-based recognition systems depends on various factors: database quality, image preprocessing, encoding techniques, etc. Given a biometric database and a selected encoding method, the capability of a recognition system is limited by the relationship between the number of classes that the recognition system can encode and the length of encoded data describing the template at a specific level of distortion. In this work, we evaluate constrained recognition capacity of biometric systems under the constraint of two global encoding techniques: Principal Component Analysis and Independent Component Analysis. The developed methodology is applied to predict capacity of different recognition channels …

Sulfate Sorption Of Acidified Forest Soils In The Otter Creek Wilderness Area, Autumn Leah Bryson
Sulfate Sorption Of Acidified Forest Soils In The Otter Creek Wilderness Area, Autumn Leah Bryson
Graduate Theses, Dissertations, and Problem Reports
Acid deposition has caused tremendous stress to forest ecosystems. Increased soil acidification due to acidic inputs from acid deposition may cause declines in forest productivity through the depletions of soil nutrients, increased mobility of aluminum and increases in acid anion concentrations, primarily nitrate and sulfate. The retention of sulfate in soil is a critical mechanism regulating soil acidification. Sulfate adsorption acts as a buffer delaying the elevation of solution sulfate concentrations. A soil will continue to adsorb sulfate until all the sites are filled and sulfate saturation is reached at which point leaching resumes. Therefore it is important to measure …
Development Of An Animal Model Of Choice Between Aversive Events, James W. Diller
Development Of An Animal Model Of Choice Between Aversive Events, James W. Diller
Graduate Theses, Dissertations, and Problem Reports
The present study examined variables controlling choice between aversive events using pigeons as subjects. Initially, a titration procedure using variable-interval (VI) schedules of food and shock delivery contingent on keypecking was conducted to determine a moderately aversive shock intensity and duration. Subjects were then presented with a choice between food delivery followed by either a single shock or three shocks in a discrete-trials procedure. The change in context affected the aversiveness of the shock. In the VI condition, shock presentation resulted in 40-60% decrease in response rates. In the discrete-trials procedure, however, responding was "all-or-none." Thus, an attempt to redetermine …
