Analysis Of Microscopic Crack Propagation In Polyurethane-Cement Stabilized Crushed Stone Based On Discrete Element Method, Yu Xin, Huang Yujie, Chen Chen, Jiang Ziqi, Wang Min, Ling Chenxin

Journal of China & Foreign Highway

To study the effect of polyurethane grouting on the crack repair performance of cement stabilized crushed stone, a microscopic model of cement stabilized crushed stone was established by the discrete element method (DEM) in this paper. SCB fracture simulation tests were conducted on specimens with different initial notch-to-depth ratios to obtain load ‒ displacement curves, and sensitivity analysis of microscopic parameters was performed. Then, by comparing microscopic characteristics such as crack propagation paths, crack types, and particle displacements before and after grouting, the repair effect of polyurethane grouting materials was evaluated. The results indicate that the grouting filler significantly enhances …

Genetic Algorithms With Psychological Tension Analysis For Music (Gaptam), Andrew Bowman

Theses

This work investigates a structurally grounded approach to algorithmic music composition using a stochastic Context Free Grammar (CFG) evolved through a genetic algorithm. While existing systems such as live-coding environments, DAWs (Digital Audio Workstations), and statistical models generate musical material, they typically lack explicit hierarchical organization, despite evidence that listeners perceive music sequentially and structurally. In this framework, derivation trees generated from an CFG serve as compositional candidates, which are evolved using subtree-based crossover and mutation. Fitness evaluation combines prior melodic heuristics with tension-based insights from music cognition research, introducing musically informed structure into the evolutionary process. A genetic system …

Thermodynamics is one of the first classes an engineer will take, where you no longer learn practical ideas; instead, the concepts become theoretical. All of thermodynamics culminates in one of the most important cycles, the Rankine Cycle. This can be very overwhelming for students as everything they've learned throughout the semester is now being put into one cycle. The primary goal is to design and build an operational Rankine cycle to demonstrate to students how it works and what each component does.

The Atmospheric Effects On The Extratropical Transition Of Hurricane Sandy, Natalie Paone

Ocean Engineering and Marine Sciences Student Publications

• Hurricane Sandy formed in the Caribbean in late October 2012 and intensified to a Category 3 hurricane before making landfall in Cuba and later New Jersey (Blake et al., 2013). Sandy caused approximately $68.7 billion in damages and over 250 fatalities, making it one of the most impactful storms in U.S. history. 
• During extratropical transition (ET), tropical cyclones interact with midlatitude systems, leading to structural changes such as expansion of the wind field, development of frontal boundaries, and increased baroclinicity (Hart and Evans, 2001). Sandy is a key example of a hybrid cyclone where ET did not weaken impacts but …

Tiny Engineers: How Polycheateworms Can Extend Sedimentary Oxic Layers And Create Better Seagrass Habitats, Natalie Spohn

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is a shallow, well mixed estuary on the East Coast of Florida. Presently, the IRL is suffering eutrophication due to a cycle of harmful algal blooms (HABs) that deplete the water column of oxygen (2,5). Deposition of organic matter from HABs in the sediment leads to reduced sedimentary oxygen, continuing to support the cycle of eutrophication through benthic-pelagic coupling (1,5). Anaerobic sedimentary conditions can increase concentrations of ammonium and sulfide, leading to seagrass loss (3,4,6,7,10). Bioturbation by infauna can extend the oxic layer of sediments, promoting aerobic processes and helping to remove nitrogen and sulfur …

Ontogeny Of Microbial Community Structure In Shoal Grass Grown In Biochar-Amended Sediments, Sajeda Slhoub, Nicole Katz, Joey Ciocher, Jack Denvir, Jenisse Louis, Katelynn Zagami

Ocean Engineering and Marine Sciences Student Publications

The Indian River Lagoon (IRL) is one of the most biologically diverse estuaries in the United States and contributes over $55.4 billion annually to Florida’s economy. Since 2010, more than 52% of the IRL seagrass meadows have been lost, reducing both the ecological and the economic potential of this ecosystem. Biochar, a stable carbon material produced by pyrolysis, added to soil enhance organic productivity perhaps because of increased microbial activity in the soil (Lehmann et al., 2017). Our study evaluates the use of biochar to grow resilient strains of seagrass for ecosystem restoration in the IRL.

Thermoelectric Migraine Cooling Cap, Emily Ralston

Ocean Engineering and Marine Sciences Student Publications

Migraines affect millions of people and can cause serious pain and discomfort. Many people use ice packs or cooling wraps to try to reduce the pain, but these only stay cold for a short amount of time. Because of this, there is a need for a cooling system that can provide longer and more controlled cooling. This project focuses on designing and building a wearable cooling cap that uses thermoelectric cooling technology. The goal is to create a system that can cool the head while moving heat away toward the neck area and help reduce migraine discomfort.

Recycling Spent Brewing Yeast As A Shrimp Feed Supplement, John Denvir

Ocean Engineering and Marine Sciences Student Publications

The aquaculture industry relies heavily on commercial fish feed, which accounts for over 50% of production costs and limits farm profitability worldwide[1]. Breweries generate about 3 gallons of high-strength wastewater per gallon of beer produced, much of it discarded as an oxygen-depleting pollutant from spent yeast[2]. Therefore, this project tests recycling spent brewer's yeast into a sustainable fish feed supplement to cut aquaculture costs and divert brewery waste from waterways, promoting circular food systems.

Factors Contributing To The Intensity Of Two 2022 Lake Effect Snowstorms At Lake Erie, Johnny Murray

Ocean Engineering and Marine Sciences Student Publications

• Lake effect snow (LES) is a weather phenomenon in which cold mass air passes over relatively warm waters, forming localized bands of snowfall. (Niziol, 1987) 
• LES events are common during the winter months in Buffalo, NY due to the city’s location along the northeastern edge of Lake Erie.
• November 17-20 and December 23-27 in 2022 were two prominent LES events.
• Total maximum snowfall for the events were 81.2” in Nov and 51.9” in Dec. 
• High snowfall totals were in part due to the length of these events, being ~60 hours in Nov, and ~120 hours in Dec.

Gamma Ray Burst Afterglow Slopes, Brian Robbins

Aerospace, Physics, and Space Science Student Publications

The standard models for gamma ray bursts (GRBs) typically assume that shockaccelerated electrons follow a power law distribution of energies. However, this behavior is not what some gamma ray bursts show. In this project, it is suggested that the presence of thermal electrons causes temporal and spectral structure across the afterglow, which is significantly different from models assuming a pure power-law distribution of electrons. To model the afterglows, we decide on a large number of samples of GRBs from the Swift database and obtain the temporal and spectral indices at arbitrary times. By finding the temporal and spectral indices at …
