Effects Of The Gravity Gradient On The Path Of 1i/‘Oumuamua, Hannah R. Richardson

Poster Presentations

In October 2017, the asteroid 1I/’Oumuamua first passed into viewing range [1]. The asteroid is notable for being the first interstellar object to enter the solar system. 1I/’Oumuamua was also unusual in its geometry; it is thought to have an aspect ratio of 6:1 and a length of approximately 400 m [2] [3]. The asteroid was observed to experience a non-Keplerian acceleration estimated to be on the order of 1×10−6 m s-2 Several theories have been proposed for the cause of this acceleration, all of which are non-gravitational in nature: volatile outgassing, photon pressure, and solar winds [1][4]. However, none …

How Do Simulated Phishing Attacks Impact Cybersecurity Awareness And The Enhancement Of Security Protocols Among Faculty Members In A University Environment?, Navnoor Sandhu

University Honors Program Senior Projects

Phishing attacks are cyber threats where attackers deceive users into performing actions that compromise the user’s security and benefit the attacker. In 2024 alone, phishing attacks have resulted in estimated damages of around 800 million dollars [1]. In response, many institutions have implemented internal simulated phishing attacks to enhance their employees' cybersecurity awareness. This training exercise has been proven beneficial in improving cybersecurity awareness on an enterprise scale[4]. This study aims to evaluate the potential effectiveness of a simulated phishing attack within a university setting, which is a relatively unseen practice thus far. Universities, like other secure organizations, store sensitive …

Theses, Dissertations and Culminating Projects

The value of seagrasses as essential fish habitat is well recognized, but limited data exist on the value of one particular species, Ruppia maritima (widgeon grass), as habitat for fish and invertebrates. During the summer of 2024, I evaluated R. maritima, Zostera marina (eelgrass) and mixed beds to assess their relative value as habitat in Barnegat Bay, New Jersey. Results from throw traps indicated significant monthly differences for pipefish, gobies, blue crabs, grass shrimp, and sand shrimp, driven by active recruitment events. When evaluating habitat type, we found no taxa that were significantly more abundant in Z. marina habitat as …

Gaussian Process Regression And Nested Sampling For Planetary Parameter Prediction, Alexandro Balarezo

Physics

In this project, we implemented a Gaussian Process (GP) regression framework using MATLAB to model two planetary (Earth) parameters, the surface temperature and albedo, as functions of planetary rotation rate and insolation (the amount of sunlight impinging on the planet). We used simulation data from the NASA ROCKE-3D general circulation model developed by the NASA Goddard Institute for Space Studies (GISS). The GP model generates a joint multivariate Gaussian distribution that is entirely captured by a covariance matrix and the output of a training data set. The covariance matrix is determined by the input data and the three hyperparameters a …

School of Biomedical Sciences

We are surrounded, in both indoor and outdoor environments, by air containing particles of biological origin (bioaerosols). We constantly inhale them, and, depending upon their size, they deposit in different parts of our airways. Despite their ubiquitous nature and our constant exposure, bioaerosol diversity and composition of the environment are not well characterized, and we understand little about which bioaerosols we are exposed to and how this impacts our health, either positively or negatively. Indoor/Outdoor Bioaerosols Interface and Relationships Network (BioAirNet), a Clean Air Programme-funded network, has recognized the need for the bioaerosol community to reflect on the current challenges …

Sevoflurane Sedation – Blind Alley Or Cunning Plan?, J Robert Sneyd, Anthony R. Absalom

More Faculty of Health Research

Low-dose inhaled sevoflurane sedation impaired volunteers' ability to complete a button-press task, without significant cardiorespiratory compromise. Patient-controlled sedation using sevoflurane might be feasible, however regulatory hurdles require proof of safety and efficacy through clinical trials. Whilst a promising concept, it must be demonstrated that patients cannot induce unconsciousness on their own, despite any interactions with opioid analgesics. Significant steps remain before practical, patient-controlled sevoflurane sedation can be implemented.

Development And Characterization Of A Pro-Angiogenic Peptide Amphiphile For Deep Dermal Burn Healing Via Spray Delivery, Loria Dimartino

Honors Theses

Severe burns and other dermatological injuries are frequently accompanied by a range of comorbidities and aesthetic challenges that patients must contend with. The complexity of burn care is exacerbated by the lack of a standardized surgical protocol, as treatment strategies are tailored to individual patient factors, including overall health status, wound size and location, as well as the expertise and resources available to the surgical team. Most commonly, deep dermal burns are treated through grafting, which effectively covers the injury site, but requires the creation of a second wound on the body of approximately the same size. This produces a …

Tailoring The Morphology Of Block Copolymers Via Solvent-Vapor Annealing, Bayleigh Madelin Loving

Honors Theses

Triblock polystyrene-polyisobutylene-polystyrene (PS-PIB-PS) copolymers have widespread applications from thermoplastic elastomers to protective coatings for ballistic applications. The incompatibility between the soft PIB and hard PS phases leads to phase separation and subsequent formation of morphological domains like lamellae and cylinders. The structures are stabilized by physical crosslinks, which can greatly improve the toughness of the triblock systems by preventing chain pullout during tensile deformation. We tailored the morphologies (achieving different morphologies with the same block copolymer) by changing the annealing conditions of the block copolymers. Solvent vapor annealing was used to selectively activate the mobility of a particular block, causing …

Globally Adaptive Exponential Integrators For Stiff Systems Of Odes, Anzhelika Vasilyeva

Honors Theses

This thesis introduces a novel method for solving systems of Ordinary Differential Equations (ODEs) resulting from the spatial discretization of Partial Differential Equations (PDEs). The proposed approach builds upon an existing technique that employs Krylov projection, which requires evaluating a matrix function at each timestep. The innovation of the new method lies in its reuse strategy, which shifts the perspective from direct matrix function evaluation to polynomial interpolation. Numerical experiments conducted on constant and variable coefficient heat equations, with both smooth and discontinuous initial data, demonstrate the computational time advantage of the new approach. The results indicate that this method …

Letters From The Periphery: L.E. Faulkner’S Crusade Against Communism, Cameron Melendez

Honors Theses

This thesis explores L.E. Faulkner’s political activism. Faulkner, a railroad executive from Hattiesburg, Mississippi, launched a number of anti-communist crusades throughout the 1940s and 1950s. Utilizing his personal correspondence, political articles, and newspapers, this thesis argues that anti-communist networks were influential and powerful tools used by Faulkner and other local activists to shape the national discourse around anti-communism. Faulkner created an interconnected web of anti-communists that linked protestant fundamentalism, capitalist advocacy, racial politics, and Americanism. His 1943–1944 civic education campaigns with Rotary International and Kiwanis International and his 1954 opposition to the World Council of Churches serve as case studies …
