Microplastics (<5mm) are a ubiquitous environmental pollutant that have the potential to cause significant harm in many fish species. Therefore, understanding the quantities at which they are being consumed by living organisms is crucial for characterizing risk. There are currently gaps in the microplastic literature regarding microplastic data from finfish...
This research was an attempt at gaining insight into the nature of the incompressibility conditions of the Navier-Stokes Equations on the Unit Circle. We realized the Riesz transformation is given in R^3 after taking the Fourier Transform of the Neumann Boundary Value problem, but this is not well defined on...
In this article, we price American options under Heston's stochastic volatility model using a radial basis function (RBF) with partition of unity method (PUM) applied to a linear complementary formulation of the free boundary partial differential equation problem. RBF-PUMs are local meshfree methods that are accurate and flexible with respect...
Plastic contamination in the world’s oceans is a considerable threat to the health of the environment, marine ecosystems and humans. In this study, the distribution and quantity of microplastics amongst mussels (Mytilus californianus) was investigated. Mussels were collected and outplanted for a year at 9 sites along the Oregon and...
We investigate the modular properties of a new partition rank, the M-d-rank of overpartitions. In fact this is an infinite family of ranks, indexed by the positive integer d, that gives both the Dyson rank of overpartitions and the overpartition M-2-rank as special cases. The M-d-rank of overpartitions is the...
The physical properties of hydrochloric acid and deuterium chloride were derived through the use of the harmonic oscillator and rigid rotor quantum mechanical models. By first obtaining angular momentum quantum values for HCl and DCl through Fourier Transform Infrared Spectroscopy, these two systems could be summed and processed with additional...
In this work we examine the dispersion of conservative tracers (bromide and fluorescein) in an experimentally constructed three-dimensional dual-porosity porous medium, and in the absence of adjustable parameters. The medium is highly heterogeneous (σ2 Y = 5.7), and consists of spherical, low-hydraulic-conductivity inclusions embedded in a high-hydraulic-conductivity matrix. The bi-modal...
Ground level electric fields arising from geomagnetic disturbances (GMDs) are used by the electric power industry to calculate geomagnetically induced currents (GICs) in the power grid. Current industry practice is limited to electric fields associated with 1‐D ground electrical conductivity structure, yet at any given depth in the crust and...
Liquid transportation fuels require costly and time-consuming tests to characterize metrics, such as Research Octane Number (RON) for gasoline. If fuel sale restrictions requiring use of standard Cooperative Fuel Research (CFR) testing procedures do not apply, these tests may be avoided by using multivariate statistical models to predict RON and...
