Automatic Determination Of Mechanical Properties From Molecular Dynamic Stress-Strain Curves Using Regression Fringe Response, Josh Kemppainen, Tristan Muzzy, Travis Wavrunek, Gregory Odegard

Michigan Tech Publications

Molecular dynamics (MD) simulations have become a powerful tool for studying polymers, designing new materials, and composites. Mechanical behavior in MD simulations are typically evaluated through stress-strain curves. However, MD-generated stress-strain curves are often obscured by thermal noise from atomic vibrations. This noise complicates the reliable derivation of mechanical properties and hinders objective and reproducible analysis. The noise in the stress-strain curves has been removed by using a Butterworth low-pass filter, enabling clearer interpretation of stress-strain data. Building on this, a novel analysis framework the Regression Fringe Response (RFR) is introduced to systematically determine the Young's modulus, yield strength, and …

Numerical Study On Mechanical Characteristics Of Positive-Negative Batter Pile Combinations At Embankment Slope Toe Under Different Pile Length Ratios, Zhou Yi, Chen Wei, Xie Zhuqing, Xia Wang, Zhou Dequan

Journal of China & Foreign Highway

Embankment filling on weak subgrades is prone to sliding and collapse failures. Positive-negative batter pile combinations were proposed to be installed at the embankment slope toe to constrain lateral deformations, but systematic inquiries into the mechanical characteristics of positive-negative batter pile combinations are still lacking. The mechanical responses of positive-negative batter pile combinations under lateral loads with different pile length ratios (1/2, 2/3, 1, 3/2, and 2/1) were systematically investigated by the finite element software Abaqus, and calculation and verification were conducted by the structural mechanics force method, providing a basis for the design of positive-negative batter pile combinations at …

Experimental Study On Compressive And Flexural Behaviors Of Pva Fiber-Reinforced Cement Soil, Lu Peng, Lu Bin, Zhang Jiahu, Zhou Siwei, Wang Jin, Hou Lijun

Journal of China & Foreign Highway

To address the problems of low toughness and poor deformation ability of cement soil, short-chopped polyvinyl a lcohol (PVA) fibers were added to modify and toughen the cement soil in this paper, and unconfined compressive and flexural tests were conducted on the PVA fiber-reinforced cement soil with different cement contents. The results show that compared with plain cement soil, the fiber-reinforced cement soil has stronger compressive deformation capacity, a flatter descending branch of the compressive stress –strain curve, a higher residual stress level, and better compressive toughness. When the cement content increases from 5% to 10%, the overall growth rates …

This paper compared and analyzed the similarities and differences between the highway carbon emission accounting systems of China and Britain, so as to explore their respective policy backgrounds, accounting methods, and application effects and provide relevant suggestions for highway carbon emission reduction in China. Through literature analysis and case …

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 …

Photochemical Activation Of Cyanine-Based Nanogels For Controlled Drug Delivery, Presley Clary

Chemistry and Chemical Engineering Student Publications

Cyanines are highly conjugated molecules with useful properties, such as ease of aggregation and fluorescence. In this project, they were incorporated into an acrylamide-based nanogel made through organic synthesis to exploit these properties for controlled drug delivery. Exposing the nanogel to nearinfrared (NIR) light causes it to react with reactive oxygen species (ROS), forming an unstable intermediate. The intermediate splits into two fragments, releasing the nanogel's cargo.1 The cargo, temozolomide, is an alkylating agent which can be used to disrupt the DNA of cancer cells.

Phenotype Variations Among Chlamydomonas Reinhardtii Under Quorum-Sensing Conditions, Marcel Pedrosa

Biomedical Engineering and Sciences Student Publications

Quorum sensing (QS) is a cell-to-cell communication system that allows unicellular microorganisms like the eukaryote C. reinhardtii to regulate phenotypic switching as a function of cell density due to the accumulation of signaling molecules.  The goal of this study is to evaluate whether QS in C. reinhardtii is regulated by nutrient availability. We propose that in a nutrient-limited environment (low nitrogen TAP (N-TAP)), cells of C. reinhardtii (cc124) would adjust their motility-driven dispersion of cells and upregulate chlorophyll and carotenoid production per cell.

Ocusensus: Real-Time Force Detection Strabismus Hook, Asa Barnhart, Niko Burger, Patricia Carrelo-Creque, Kristie Fonseca

Biomedical Engineering and Sciences Student Publications

Strabismus affects approximately 2–5% of the general population [1]. Primary treatment is (strabismus) surgery but current methods result in approximately 36% of patients undergoing reoperation within 5 years [2]. One factor proposed to contribute towards reoperation is insufficient force applied to extraocular muscles during surgery. Excessive force triggers the oculocardiac reflex (OCR) which lowers heart rate by >20%[3]

Carmen Manrique De Quintero: A Forgotten Legacy In Colombian Piano Music, Lina Maria Luisa Marín Diaz

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This doctoral document investigates the life and piano works of Carmen Manrique de Quintero (1871–1931), a pivotal yet overlooked figure in Colombian music history. Positioned as a stylistic bridge between the nineteenth-century estética del salón [salon aesthetics] and the professionalization of the Colombian composer, Manrique de Quintero’s output represents a sophisticated synthesis of European forms and Colombian national rhythms. Despite her membership in the influential Garay artistic lineage and her prolific body of work, her legacy has suffered from editorial blurring, fragmented documentation, and systematic intellectual appropriation. Using a multidisciplinary approach of genealogical reconstruction and artistic archaeology, this study restores …

Humanoid Lidar–Rgb-D Calibration For Environment- Agnostic 3d Auto-Alignment, Howard Hua

Electrical and Systems Engineering Undergraduate Student Research

This paper presents an environment-agnostic automatic LiDAR-RGB-D calibration method for a Unitree G1 humanoid platform. The proposed pipeline reconstructs depth-camera observations into 3D point clouds and aligns them directly with LiDAR point clouds, avoiding the need for calibration targets or manual adjustment. The method applies explicit preprocessing, coarse simulated annealing, polish simulated annealing, a symmetric nearest-neighbor alignment objective, and final point-to-plane local refinement. Experimental results show that the coarse simulated annealing stage provides most of the calibration correction, while the polish stage and local refinement further improve convergence and alignment accuracy. Overall, this framework demonstrates a practical target-free approach for …

Worldview-Bench: A Benchmark For Evaluating Global Cultural Perspectives In Large Language Models, Abdullah Mushtaq, Imran Taj, Rafay Naeem, Ibrahim Ghaznavi, Junaid Qadir

All Works

Background: Large Language Models (LLMs) are predominantly trained and aligned in ways that reinforce Westerncentric epistemologies and socio-cultural norms, leading to cultural homogenization and limiting their ability to reflect global civilizational plurality. Existing benchmarking frameworks fail to adequately capture this bias, as they rely on rigid, closed-form assessments that overlook the complexity of cultural inclusivity. Objectives: To address this cultural bias problem, we introduce WorldView-Bench, a benchmark designed to evaluate Global Cultural Inclusivity (GCI) in LLMs by analyzing their ability to accommodate diverse worldviews. Methods: Our approach is grounded in the Multiplex Worldview proposed by Senturk et al., which distinguishes …

Repurposing An Old Pc Into A Self-Hosted Cloud And Media Server, Riley Biggins

Honors Theses

Commercial cloud platforms rely heavily on subscription models, so everyday users fall into a "cloud trap" summarized by perpetual fees, forfeited privacy, and a lack of true asset ownership. At the same time, functioning consumer electronics get discarded as e-waste when they fail to meet the hardware requirements of modern operating systems. This project presents a sustainable and cost-effective alternative to both issues by repurposing a 2017 HP Pavilion laptop into a personal cloud and media server.

Despite severe hardware constraints, my software architecture rivals the utility of paid services. By replacing Windows with a headless installation of Ubuntu Server, …

Price Dispersion In Online Markets Increases During Periods Of Higher Demand As Firms Use Dynamic Pricing Strategies To Maximize Revenue Under Demand Uncertainty., Brooke Stewart

Honors Theses

This study investigates the phenomenon of price dispersion in online retail markets during high-demand periods, focusing on the role of dynamic pricing under conditions of demand uncertainty. Although online markets operate in a transparent way, and consumers find it cheap to search them, the price dispersion phenomenon, when the same product is sold at varying prices by various vendors, persists. The study discusses the case of higher dispersion of prices in high-demand times like holidays, sales events, or shortages of goods when there is uncertainty about the future demand, causing dynamic pricing models. In analyzing the price of 25 the …

Is Dpph A Candidate Molecule For Quantum Computing Research At Room Temp Via Esr Spectroscopy?, Amber Mcnaughton

2026 Undergraduate Research Showcase

Quantum computing is a rapidly developing field in physics with the potential to solve complex problems that are beyond the capabilities of classical computers. This advantage comes from the use of qubits, which can exist in multiple states rather than the fixed binary states of classical bits. A major challenge in quantum computing research, however, is that most experiments require extremely low temperatures — often near −270°C — to maintain quantum behavior. Achieving these temperatures demands expensive, specialized equipment, making such research difficult to access for many scientists.

The organic molecule diphenyl-picryl-hydrazyl (DPPH) offers a promising solution to this limitation. …

Climate Controls On Glacier Snow Cover Variability In Western North America, Madelyn R. Woods, Ellyn M. Enderlin, Rainey Aberle
