Incorporating Histograms Of Oriented Gradients Into Monte Carlo Localization, Michael K. Norris

Master's Theses

This work presents improvements to Monte Carlo Localization (MCL) for a mobile robot using computer vision. Solutions to the localization problem aim to provide fine resolution on location approximation, and also be resistant to changes in the environment. One such environment change is the kidnapped/teleported robot problem, where a robot is suddenly transported to a new location and must re-localize. The standard method of "Augmented MCL" uses particle filtering combined with addition of random particles under certain conditions to solve the kidnapped robot problem. This solution is robust, but not always fast. This work combines Histogram of Oriented Gradients (HOG) …

Comparison Of Energy Analysis Platforms For Title 24compliance, Holli L. Tripp

Construction Management

The 2013 Building Energy Efficiency Standards for Low-Rise Residential Buildings allow users to demonstrate compliance via two methods: performance or prescriptive. Prescriptive documentation requires analysis to be conducted by-hand while performance compliance utilizes computer modeling software to analyze trade-offs, and demonstrate compliance through alternative building design parameters. Typically computer demonstrated compliance via the performance method is the most popular choice because it allows for complex buildings to be analyzed using their actual metrics which results in a more accurate report of proposed energy consumption (Ross, 2016). This method however requires additional software outside of the tools that architects and designers …

Just Meat: Chicken-Pain, Intergenerational Justice, And The American Diet, Stephen Scales

Between the Species

Peter Singer’s arguments against the morality of the typical American diet focus on the pain of animals, and lead to the conclusion that we must become committed vegans. His approach ignores the impact that different psychological capacities can legitimately have on our moral appraisal of the interests of beings. Although we ought to eat less meat because of the externalized environmental costs that factory farming inflicts upon future people, an ideal diet may contain some environmentally sustainably raised meat. Finally, the perception of ethical puritanism in committed vegans may be an obstacle to achieving the real reductions in animal suffering …
