In this thesis, the perturbation-based decomposition technique developed by Szlavik [1] was used in an attempt to solve the inverse problem in EEG source localization. A set of dipole locations were forward modeled using a 4-layer sphere model of the head at uniformly distributed lead locations to form the vector basis necessary for the method. Both a two-dimensional and a pseudo-three-dimensional versions of the model were assessed with the two-dimensional model yielding decompositions with minimal error and the pseudo-three-dimensional version having unacceptable levels of error. The utility of interpolation as a method to reduce the number of data points to …

College Students' Disenfranchised Grief Following A Breakup: The Effect Of Relationship Closeness And Perceived Stigma On Grief, Jennifer E. Reimer

Master's Theses

Grief is a universal reaction to loss. Losses are often associated to the death of a loved one, however, they may also originate from the end of an intimate partner relationship. Whereas studies have focused on grief after a divorce or on symptomology students endure after a death, this article attends to the understudied college student experience of grief following a breakup. Within emerging adulthood, the loss of a close romantic relationship may be challenging to navigate alongside the daily stressors of college. Stigmatization by means of social cues convey sentiments, such as the need to get over an ex-partner, …

A Comparison Of Water Main Failure Prediction Models In San Luis Obispo, Ca, Kyle Eric Aube

Master's Theses

This study compared four different water main failure prediction models: a statistically simple model, a statistically complex model, a statistically complex model with modifications termed the 2019 model, and an age-based model. The statistically complex models compute the probability of failure based on age, size, internal pressure, length of pipe in corrosive soil, land use, and material of the. These two values are then used to prioritize a water main rehabilitation program to effectively use the municipality’s funds. The 2019 model calculates the probability of failure and consequence of failure differently than the statistically complex model by considering corrosive soil …

Cloneless: Code Clone Detection Via Program Dependence Graphs With Relaxed Constraints, Thomas J. Simko

Master's Theses

Code clones are pieces of code that have the same functionality. While some clones may structurally match one another, others may look drastically different. The inclusion of code clones clutters a code base, leading to increased costs through maintenance. Duplicate code is introduced through a variety of means, such as copy-pasting, code generated by tools, or developers unintentionally writing similar pieces of code. While manual clone identification may be more accurate than automated detection, it is infeasible due to the extensive size of many code bases. Software code clone detection methods have differing degree of success based on the analysis …

System Design And Analysis For Creating A 3d Virtual Street Scene For Autonomous Vehicles Using Geometric Proxies From A Single Video Camera, Timothy Wong

Master's Theses

Self-driving vehicles use a variety of sensors to understand the environment they are in. In order to do so, they must accurately measure the distances and positions of the objects around them. A common representation of the environment around the vehicle is a 3D point cloud, or a set of 3D data points which represent the positions of objects in the real world relative to the car. However, while accurate and useful, these point clouds require large amounts of memory compared to other representations such as lightweight polygonal meshes. In addition, 3D point clouds can be difficult for a human …

Smart Dc Wall Outlet Design With Improved Load Voltage Detection, Patrick Donovon Granieri
