Accurate Range-Based Indoor Localization Using Pso-Kalman Filter Fusion, Paul Bupe Jr

College of Graduate Studies: Theses & Dissertations

Accurate indoor localization often depends on infrastructure support for distance estimation in range-based techniques. One can also trade off accuracy to reduce infrastructure investment by using relative positions of other nodes, as in range-free localization. Even for range-based methods where accurate Ultra-WideBand (UWB) signals are used, non line-of-sight (NLOS) conditions pose significant difficulty in accurate indoor localization. Existing solutions rely on additional measurements from sensors and typically correct the noise using a Kalman filter (KF). Solutions can also be customized to specific environments through extensive profiling. In this work, a range-based indoor localization algorithm called PSO - Kalman Filter Fusion …

The Effects Of Boring Sponge Infestation On Condition, Growth, And Sex Change In Crepidula Fornicata, Nicole L. Kleinas

College of Graduate Studies: Theses & Dissertations

The Atlantic slipper limpet, Crepidula fornicata, is a sequential hermaphrodite whose size at sex-change is plastic with respect to social and population cues. As an organism allocates energy between growth, reproduction and maintenance, an increased cost of one process may affect another. In this paper, I evaluate whether the presence of an epibiotic sponge (Cliona celata) affects the growth, condition and sex-change of C. fornicata individuals. Population surveys demonstrate a variable effect of Cliona presence on C. fornicata condition. The results of a twelve-week in situ experiment demonstrated a decrease in growth when C. celata was present. …

Evolution Of Two-Element Directive Antennas, Tyler J. Mcpherson

College of Graduate Studies: Theses & Dissertations

The classic Yagi antenna is often utilized to provide directional radiation. Many facets of the Yagi antenna can be improved. This thesis focuses on the evolution of the two-element directive antennas, such as the Yagi antenna, in three ways. First, the inter-element spacing is reduced beyond those previously mentioned in literature. Next, an electrically-small version of the two-element Yagi with extremely close inter-element spacing is explored with a linear polarized and a circularly polarized configuration. Finally, further analysis of a wideband, circularly polarized, two-element, directive antenna with standard interelement spacing is performed.

For the second study, we analyzed mental health data tuning the parameters of the decision tree (splitting method, depth and entropy). …

Phase-Locked Loop Control In Low-Inertia Grid-Connected Voltage-Source Converters, Ifechukwude Gideon Odogwu

College of Graduate Studies: Theses & Dissertations

As the integration of renewable energy on the grid increases, the number of voltage-source converters (VSC) installed also does. VSC controls both switch turn-on and turn-off, allowing a dc voltage source to be switched between phases. For the converter to accurately synchronize with the grid, a phase-locked loop (PLL) is used for the frequency measurements of the grid. However, the implementation of PLL with measurement delay introduces harmonics, noise, high frequency, and voltage oscillation to the system due to its dynamics. The dynamics introduced to the grid can be ignored under stiff grid conditions, but power from renewable sources decreases …

Although handwritten character recognition from the manuscript image is challenging, the advancement of modern machine learning techniques makes it astonishingly manageable. The problem of accurately recognizing handwritten character remains of high practical interest since a large number of manuscripts are currently not digitized, and hence inaccessible to the public. We create our repository of the datasets by cropping each letter image manually from the manuscript images. The availability of datasets is …

Place Vulnerability Assessment In Coastal Georgia, Usa, Bless Dupeh

College of Graduate Studies: Theses & Dissertations

The complexity of vulnerability to natural hazards requires a thorough assessment of both physical and social factors. Physical vulnerability explains the occupancy within hazardous zones and social vulnerability determines how a community can cope, respond to, and recover from disasters. The determination of both physical and social vulnerability helps find the overall vulnerability of a place and this in turn helps with hazard mitigation. This study assesses the overall place vulnerability by examining both physical and social vulnerability in six Coastal Georgia counties. This study also uses Principal Component Analysis (PCA) to generate a social vulnerability index. To obtain the …

The Mechanical Development For An Autonomous Forest Service Robot, James P. Walker

Honors College Theses

Georgia’s forests are under threat from numerous invasive species of plant, both herbaceous and woody. A primary factor in the invasive potential of any given non-native plant is the lack of natural predators and rapid reseed and regrowth cycles. To combat invasive plants, this thesis proposes an artificial, robotic predator to provide a means of controlling invasive species. Although autonomous robots are currently being developed for similar agricultural purposes, none have emerged for forestry related tasks, such as proposed in this work. The chassis, inspired by rocker bogie and similar suspension systems, has been redesigned to have eight wheels, to …
