Urban Scale Vehicle-To-Building-To-Grid Integration Leveraging Human Mobility Modeling, Yapan Liu

Dissertations - ALL

In the United States (U.S.), the buildings sector consumes about 76% of electricity use and 40% of all primary energy use and associated greenhouse gas emissions. Occupant behavior, which includes the presence of people in the space, interactions between the occupant and building systems, and occupant adaptations to the built environment, has a significant impact on the energy consumption of buildings. Many researchers have investigated occupant behaviors at a single building scale, however, very few studies have been conducted at the community scale or urban scale. Our previous review study introduced human mobility modeling approach from other domains into the …

Pedestrian Crossing Environmental Impact Statement, Alyssa Gaither

Undergraduate Honors Capstone Projects

Logan, Utah is divided by US Highway 89/91, which bisects much of the city. This makes it difficult to pass to the other side without a vehicle. A pedestrian crossing has been proposed to connect the eastern and western sides of Logan without impacting traffic flow. The Environmental Impact Statement aims to look at reasonable alternatives and identify many resources that will be affected by its implementation. Four main alternatives were considered: an underpass, an overpass with an elevator, an overpass with a ramp, and the no-change alternative to be used as a baseline alternative. The underpass is the preferred …

Recent major investments in infrastructure in the United States and globally present a crucial opportunity to embed equity within the heart of resilient infrastructure decision-making. Yet there is a notable absence of frameworks within the engineering and scientific fields for integrating equity into planning, design, and maintenance of infrastructure. Additionally, whole-of-government approaches to infrastructure, including the Justice40 Initiative, mimic elements of process management that support exploitative rather than exploratory innovation. These and other policies risk creating innovation traps that limit analytical and engineering advances necessary to prioritize equity in decision-making, identification and disruption of mechanisms that cause or contribute to …

Developing More Useful Equity Measurements For Flood-Risk Management, Adam Pollack, Casey Helgeson, Carolyn Kousky, Klaus Keller

Dartmouth Scholarship

Decision-makers increasingly invoke equity to motivate, design, implement and evaluate strategies for managing flood risks. Unfortunately, there is little guidance on how analysts can develop measurements that support these tasks. Here we analyse how equity can be defined and measured by surveying 167 peer-reviewed publications that explicitly state an interest in equity in the context of flood-risk management. Our main result is a taxonomy that systematizes how equity has been, and can be, defined and measured in flood-risk research. The taxonomy embodies how equity is a pluralistic and unavoidably ethical concept. Despite this, we find that most quantitative studies fail …

Floating Treatment Wetlands For Zinc Phytoremediation, Grace Duong

Undergraduate Research Conference at Missouri S&T

Stormwater pollution from urban and mining areas can pose challenges to downstream waters because of zinc contamination. Floating treatment wetlands (FTWs) have demonstrated the ability to mitigate nutrient and metal contamination. To investigate the effectiveness of native Missouri plants in FTWs, fourteen 10-liter mesocosms were constructed, dosed with nutrients, and placed in a greenhouse. Four mesocosms acted as controls, five contained pickerelweed, and five contained palm sedge. After one week of acclimation, mesocosms were dosed with ZnCl2 in concentrations of 0, 5, and 10 mg/L of zinc. Objectives of this study include characterizing zinc immobilization and assessing both pickerelweed and …

Leveraging Systems Thinking For Global Environmental Health, Martha M. Mcalister

USF Tampa Graduate Theses and Dissertations

Environmental health inequities such as household air pollution, inadequate water, sanitation, and hygiene, and chemical pollution persist globally and have myriad consequences on individual and societal well-being. Unfortunately, while billions of dollars and countless hours of research have been applied towards addressing these issues in development, humanitarian, and environmental justice contexts, attempts to reduce the environmental burden of disease can seem successful at first, but then backslide to pre-intervention conditions (or worse). This is indicative of policy resistance, a tendency of complex systems that makes it very difficult to enact change if the “rules” of the system are misunderstood. There …

Modeling Recovery Of The Florida Electric Transmission Grid After Severe Weather Event, Wei B. Guan

Theses and Dissertations

Predicted changes to the climate are expected to increase the frequency and severity of extreme weather events. The Florida electric grid is a critical infrastructure system susceptible to severe weather events, especially hurricanes, causing widespread damage and outages. A foundational concept of the electric grid’s resilience is its ability to recover after extreme weather events, such as hurricanes and flooding. The recovery of the electrical grid after an extreme event is predicated upon the electrical asset's remoteness and the component's level of damage. Using fragility analysis, previous models have assessed the mean time to recover for transmission towers and substations …

The United States Environmental Protection Agency (US EPA) manages the clean up of contaminated sites that pose a significant risk to human health and the environment under the Superfund program. A site can become contaminated if hazardous waste from industrial operations are mismanaged or dumped into the environment, in an uncontrolled manner. In this study, a proposed Superfund site (Mohawk Tannery in Nashua, New Hampshire), an active Superfund site (Ciba-Geigy Corp. in Toms River, New Jersery), and a …

A Study Of Multimodal Accessibility Equity And Spatio-Temporal Relationships Between Transit, Job Density And Modal Split, Seyedsoheil Sharifiasl

Planning Dissertations - Archive

In North American cities, the land use and transportation systems are associated with low-density, suburban-type urban development, where the built environment contributes to a mobility pattern that is extremely reliant on automobiles. Several studies in the past decades have documented noticeable and concerning patterns of unjust and unsustainable transportation in this context. As a result, for those population groups with limited access to private transportation, this form of urban structure is equivalent to limited access to opportunities, leading to various environmental and social problems. These problems exacerbate inequities in access to transportation, disproportionately affecting marginalized communities. From a sustainable development …
