Whole farm experimentation: Making it profitable
(2022-12)
The first essay considers Bayesian Kriging (BK), which provides a way to estimate spatially varying coefficient regression models where the parameters are smoothed across space. The problem is that previous methods are too ...
To believe or not to believe: Religious/spiritual and secular identity group differences in quality of life and psychological distress in college students
(2022-07)
Religiosity and spirituality often provide core coping structures to believers. College students are regularly put into novel situations and environments in which they must rely on their coping mechanisms, including practices ...
Factors associated with lowered likelihood of suicidal ideation for trans and nonbinary individuals
(2022-07)
It is estimated that approximately one million people die by suicide each year around the world (World Health Organization, 2014). However, it has been demonstrated that marginalized individuals experience higher rates of ...
Application of surrogate modeling methods in simulation-based reliability and performance assessment of civil structures
(2020-12)
Structures and infrastructure systems are subjected to various deterioration processes due to environmental or mechanical stressors. Proper performance assessment approaches capable of detecting potential structural damage ...
Stability of 2D partially dissipative Boussinesq equations and 3D rotating Boussinesq equations
(2022-07)
Examining the stability of nonlinear partial differential systems near a physically relevant equilibrium with suitable perturbation is a fundamental problem in fluid dynamics. This dissertation solves the stability and ...
Interfacial effects on the chiral domain walls in ultrathin PT/CO/ALOₓ heterostructures for the futuristic spintronics devices
(2023-05)
Heavy metal /ferromagnet/metal oxide heterostructures are important due to their immense prospects for establishing spin textures such as chiral domain walls which are the basic ingredient of low power and capacious ...
Modeling the ionizing radiation environment in Earth's atmosphere
(2021-05)
The constant bombardment of the Earth by cosmic radiation leads to an atmospheric radiation environment comprised of many species of energetic secondary particle. Aside from carrying out full Monte Carlo simulations from ...
Exploring indigenous language and psychological health among Kickapoo Tribe bilinguals
(2020-07)
Studies show thinking and speaking in a foreign language provides a greater emotional and cognitive distance than the speaker’s native language (Keysar et al., 2012). The prospect of such a detachment of cognition is of ...
Spatial and temporal patterns of soil moisture: A study on soil moisture observation and modeling
(2020-05)
This dissertation addressed three research questions related to observing and modeling soil moisture spatial and temporal patterns. 1) What is the spatial pattern like for soil moisture at the mesoscale? A mobile device ...
Nutrient cycling in switchgrass and soil health as affected by cover crops
(2020-05)
The focus of these studies was nutrient management of specialty crops. Management practices for switchgrass fertilization in production of biofuel feedstock and forage hay are variable depending on climate, harvest timing ...
