The Long And Winding Road To Carbon Neutrality: Can California’S Zero Emission Vehicle Survive The Twists And Turns Of The Legal System?, Erin Hudak Jun 2023

The Long And Winding Road To Carbon Neutrality: Can California’S Zero Emission Vehicle Survive The Twists And Turns Of The Legal System?, Erin Hudak

San Diego Journal of Climate & Energy Law

The effects of climate change are becoming more and more obvious every year, evidenced by extreme weather events, rising sea levels, and increased global temperature. In an effort to mitigate the damage caused by greenhouse gases, California Governor Gavin Newsom announced a goal to have all new passenger vehicles sold in California be Zero-Emission Vehicles (“ZEVs”) by 2035. This Article explores the possible legal issues that California’s ZEV mandate faces now and may face in the future. First, California will likely face a federal preemption challenge under the Clean Air Act. Second, the California Air Resources Board’s authority to mandate …


Prediction & Active Control Of Multi-Rotor Noise, Samuel O. Afari Apr 2023

Prediction & Active Control Of Multi-Rotor Noise, Samuel O. Afari

Doctoral Dissertations and Master's Theses

Significant developments have been made in designing and implementation of Advanced Air Mobility Vehicles (AAMV). However, wider applications in urban areas require addressing several challenges, such as safety and quietness. These vehicles differ from conventional helicopter in that they operate at a relatively lower Reynolds number. More chiefly, they operate with multiples of rotors, which may pose some issues aerodynamically, as well as acoustically. The aim of this research is to first investigate the various noise sources in multi-rotor systems. High-fidelity simulations of two in-line counter-rotating propellers in hover, and in forward flight conditions are performed. Near field flow and …


Seeing Environmental Injustice Through Moss-Colored Glasses: Neighborhood Monitoring Of Toxic Metal Air Pollution Disparities With Orthotrichum Lyellii, Allison Hayes Jan 2023

Seeing Environmental Injustice Through Moss-Colored Glasses: Neighborhood Monitoring Of Toxic Metal Air Pollution Disparities With Orthotrichum Lyellii, Allison Hayes

WWU Graduate School Collection

Toxic air pollution in the United States has been regulated through the Clean Air Act (CAA) since the 1970’s. Yet, a growing body of research suggests that the CAA’s air pollution management system has several blind spots. The CAA’s inability to identify and remedy pollution hot spots across the country. These hot spots are areas where air pollution exists but are often entirely overlooked because of the extreme hyperlocal scale and the current methods for identifying areas of concern outlined in the CAA for the Environmental Protection Agency. Researchers find that these hot spots are more prevalent in minority and …
