The Role Of Adverse Childhood Experiences And Associated Features On Criminality In Emerging Adults, Jessica L. Harangozo

ETD Archive

Adverse Childhood Experiences (ACEs) are associated with a variety of negative outcomes, including criminal and violent behaviors (Milaniak & Widom, 2015). Prior research indicates that antisocial personality traits such as callousness may play a mediating effect on the relationship between ACEs and criminality (Baglivio et al., 2020). Further, the developmental period in which childhood maltreatment occurs may be related to greater criminality (Thornberry et al., 2010). This research project aims to examine how ACEs relate to criminality in emerging adults, with consideration of antisocial personality traits and the developmental period of experiencing childhood abuse. This study hypothesizes: (A) Both higher …

Physics-Based Proxy Modeling Of Co2 Sequestration In Deep Saline Aquifers, Aaditya Khanal, Md Fahim Shahriar

Jasper Department of Chemical Engineering Faculty Publications and Presentations

The geological sequestration of CO2 in deep saline aquifers is one of the most effective strategies to reduce greenhouse emissions from the stationary point sources of CO2. However, it is a complex task to quantify the storage capacity of an aquifer as it is a function of various geological characteristics and operational decisions. This study applies physics-based proxy modeling by using multiple machine learning (ML) models to predict the CO2 trapping scenarios in a deep saline aquifer. A compositional reservoir simulator was used to develop a base case proxy model to simulate the CO2 trapping mechanisms (i.e., residual, solubility, and …

Four-Field Hamiltonian Fluid Closures Of The One-Dimensional Vlasov-Poisson Equation, C. Chandre, Bradley Allan Shadwick

Department of Physics and Astronomy: Faculty Publications

We consider a reduced dynamics for the first four fluid moments of the one-dimensional Vlasov-Poisson equation, namely, the fluid density, fluid velocity, pressure and heat flux. This dynamics depends on an equation of state to close the system. This equation of state (closure) connects the fifth order moment—related to the kurtosis in velocity of the Vlasov distribution—with the first four moments. By solving the Jacobi identity, we derive an equation of state which ensures that the resulting reduced fluid model is Hamiltonian. We show that this Hamiltonian closure allows symmetric homogeneous equilibria of the reduced fluid model to be stable.
