The Relationship Between Urban Tree Lai And Urban Heat, Amanda Sheepherd, Dr. Ryan Jensen

Journal of Undergraduate Research

It is well known that urban areas are warmer than the surrounding rural areas, with various negative (though sometimes not immediately perceived) consequences for urban residents and the environment. As the world’s human population becomes increasingly urban, methods of mitigating urban heat become more imperative to explore. Though not nearly as abundant as in many natural environments, trees are fairly common in urban areas and can be utilized to offset urban heat. Studying the cooling effects of trees on the surrounding areas can further our understanding of the relationship between trees and temperature. Leaf Area Index (LAI) is a specific …

A Diagnostic Metric For Predicting Tropical Cyclone And Mid-Latitude Floods, Jonathon Klepatzki, Shawn M. Milrad

Beyond: Undergraduate Research Journal

This study details a dynamic and thermodynamic metric (i.e., Extreme Flood Index [EFI]) designed to diagnose the frequency and intensity of extreme precipitation events associated with stagnant mid-latitude flow patterns (i.e., Rex blocks). As the global climate warms, rapid Arctic warming may be helping to slow the mid-latitude westerly jet stream, resulting in increased mid-latitude flow stagnation. The combination of long-duration ascent associated with easterly winds and warm moist air increases the severity of extreme precipitation events; as such, the EFI is specifically designed to detect this potent combination of ingredients. In 2013, a Rex block stalled a low-pressure system …

Patterns Of The Past: Mountain Hemlock And Pacific Northwest Climate, Aaron Snow, Dr. Matthew Bekker

Journal of Undergraduate Research

In July, 2016, I had the opportunity to attend the North American Dendroecological Fieldweek (NADEF) at Mount Rainier National Park, Washington. NADEF organizes the attendees into five different groups to undergo specific research projects all having to do with tree rings. My group, the intro group, hiked to the southern side of the park, assembled a chronology of mountain hemlock trees (Tsuga mertensiana), and observed notable attributes of the collected data. Because the fieldweek lasted only seven days, our research was minimal, which was why I applied for an ORCA grant in order to take the research to …

The Dangers Of Human-Like Bias In Machine-Learning Algorithms, Daniel James Fuchs

Missouri S&T’s Peer to Peer

Machine learning algorithms (MLAGs), frequently used in artificial intelligence (AI), rely on using patterns across sets of data to derive decision-making intelligence. In recent years, as society continues to give increasing authority to ML-driven AIs, these algorithms have demonstrated the ability to take on human-like discriminatory biases. Microsoft's "Tay," for example, a social media-based chatbot, went from resembling a normal teenage girl to displaying racist and sexist attitudes in a mere sixteen hours). Tay and many other ML-driven implementations across a wide variety of fields have replicated numerous human biases. In most cases, these human-like biases originated due to improper …

Golden Arm: A Probabilistic Study Of Dice Control In Craps, Donald R. Smith, Robert Scott Iii

UNLV Gaming Research & Review Journal

This paper calculates how much control a craps shooter must possess on dice outcomes to eliminate the house advantage. A golden arm is someone who has dice control (or a rhythm roller or dice influencer). There are various strategies for dice control in craps. We discuss several possibilities of dice control that would result in several different mathematical models of control. We do not assert whether dice control is possible or not (there is a lack of published evidence). However, after studying casino-legal methods described by dice-control advocates, we can see only one realistic mathematical model that describes the resulting …

Addressing The Regulator's Dilemma: A Self Drive Framework For Balancing Safety And Innovation, Craig Maughan

Brigham Young University Prelaw Review

Policymakers are tasked with creating regulations that responsibly oversee the growth and deployment of emerging technologies. I argue that the SELF DRIVE Act, currently being deliberated in Congress, offers one such intelligent regulatory structure for autonomous vehicles: it prioritizes public safety over adherence to outdated requirements, giving innovators greater freedom to field-test new designs. More importantly, I examine how key principles of the SELF DRIVE Act should be applied to other emerging technologies currently facing regulatory roadblock. Specifically, I suggest the drone industry be subject to regulatory changes that incentivize safety, allow exploration, and anticipate future growth. Such regulations allow …

How Effluent Compares To Storm Runoff In Relation With Surface Water Quality, Nicholas Krebs

D.U.Quark

Waste water treatment plants are considered simple solutions for poor surface water quality and are used in every developed and developing society. There are varying types of waste treatment plants. The systems are rarely able to purify all water that passes through the system. The problem with a mix-and-treat waste water system is the strain from sudden influxes of water. Systems that combine storm runoff accept variability in the volume of water that needs treating. Effluent is discharged when the plant cannot treat all the waste. The purpose of this review is to determine which system is the closest to …
