Fridge Tracker And Recipe Provider : Fridgechamp, Matt Dudek

Williams Honors College, Honors Research Projects

FridgeChamp is a website to allow people to track their fridge/pantry contents while providing them recipes they can make with said ingredients. Currently there are few ingredient trackers and recipe matchers that exist as websites, and of those many lack simplistic recipes that a home chef would use. In addition to lacking some recipes, many tracker/recipe apps do not have a function to remove from your stock what a recipe requires, making you tediously update the stock every time you cook/use something.

Whiteboard Drawing Device, Stefan Ilic, Andrew Adams, Vaughn Richards, James Medved

Williams Honors College, Honors Research Projects

Whiteboards have become a staple in many classrooms, especially in the context of STEM courses. However, when it comes to teaching complex topics, it can be difficult or impractical to provide accurate drawings and visualizations by hand, and in extreme cases may lead to misinterpretation of a particular topic. To fix this issue, the Whiteboard Drawing Device allows users to draw preset shapes to a whiteboard automatically, both quickly and accurately. Using either a smartphone application or a set of onboard controls, the device allows users to automatically draw straight lines, rectangles, triangles, sinusoidal waves, and circles on the whiteboard. …

Application Of Machine Learning Techniques For Traffic State Estimation, Pattern Recognition, And Crash Detection, Muhammad Usama

Dissertations

In the quest to optimize traffic management through machine learning (ML), this dissertation delves into three foundational areas: Traffic state estimation (TSE), traffic pattern classification, and traffic crash detection. The first facet of this dissertation focuses on TSE. Traditionally, TSE methods are categorized into two approaches: model and data-driven methodologies, each with its limitations. Data-driven ML models can falter with limited training data or misleading samples. Moreover, their “black-box” nature makes them hard to interpret. This research introduces a physics-based neural network (PINN) framework that combines the strengths of both TSE methods. The presented approach uses limited observational speed data …

Joint Sonar And Communication (Soncomm) System Using Solvable Chaos, Tamseel Mahmood Syed

Dissertations

An ever increasing number of actively interconnected wireless devices tend to exert congestion on the naturally limited resources provided by the electromagnetic spectrum. This fact imposes a significant engineering challenge on efficient utilization of communication channels. One method to lessen the stringency of the spectrum access is to combine functionality of wireless applications via jointly operational (multi-purpose) waveforms. Solvable chaos was previously shown to have inherent detection benefits when used independently in practical demonstrations of either acoustic ranging or communication. This dissertation focuses on the design of a joint sonar-communication (SonComm) system via solvable chaotic waveforms. First, individual hardware demonstrations …

Bioimpedance-Based Real-Time Wearable Physiological Monitoring, Robert Joseph Mathews

Modeling The Bidirectional Relationship Between Shared-Patient Physician Networks And Patient Longitudinal Treatment Patterns: Application To Physician Risky-Prescribing, Xin Ran

Dartmouth College Ph.D Dissertations

Risky-prescribing is a pressing public health concern in the United States. Opioids, benzodiazepines, and non-benzodiazepine sedative-hypnotics (sedative-hypnotics) are three commonly-prescribed but potentially risky drug groups, prescribed alone or in combination. Physician shared-patient networks provide a unique perspective in studying physician network characteristics and structures, as well as their association with the delivery of health care. Understanding how physician shared-patient networks are related to their prescribing may inform network-based interventions targeting risky-prescribing, which is yet to be fully studied.

We investigated patient receipt of risky prescriptions and physician risky-prescribing intensity through the scope of shared-patient networks. We used retrospective Medicare insurance …

Triangular Modular Curves Of Low Genus And Geometric Quadratic Chabauty, Juanita Duque Rosero

Dartmouth College Ph.D Dissertations

This manuscript consists of two parts. In the first part, we study generalizations of modular curves: triangular modular curves. These curves have played an important role in recent developments in number theory, particularly concerning hypergeometric abelian varieties and approaches to solving generalized Fermat equations. We provide a new result that shows that there are only finitely many Borel-type triangular modular curves of any fixed genus, and we present an algorithm to list all such curves of a given genus.

In the second part of the manuscript, we explore the problem of computing the set of rational points on a smooth, …

Icing Mitigation Via High-Pressure Membrane Dehumidification In An Aircraft Thermal Management, Danielle D. Hollon

Browse all Theses and Dissertations

Icing, or the formation of ice from water via freezing or water vapor via desublimation, is a phenomenon that commonly occurs within air cycle-based refrigeration systems and requires thermal control that limits system performance. In aircraft applications icing frequently occurs in the heat exchangers and turbine(s) that are part of the air cycle machine, the refrigeration unit of the environmental control system. Traditionally, water vapor is removed from an air cycle machine via condensing in a heat exchanger and subsequent high-pressure water separation. This approach is not capable of removing all of the vapor present at low altitude conditions, corresponding …

Nitrate-Stimulated Release Of Naturally Occurring Sedimentary Uranium, Jeffrey Westrop, Pooja Yadav, Pj Nolan, Kate M. Campbell, Rajesh Singh, Sharon E. Bone, Alicia H. Chan, Anthony Kohtz, Donald Pan, Olivia Healy, John R. Bargar, Daniel D. Snow, Karrie A. Weber

Department of Earth and Atmospheric Sciences: Faculty Publications

Groundwater uranium (U) concentrations have been measured above the U.S. EPA maximum contaminant level (30 μg/L) in many U.S. aquifers, including in areas not associated with anthropogenic contamination by milling or mining. In addition to carbonate, nitrate has been correlated to uranium groundwater concentrations in two major U.S. aquifers. However, to date, direct evidence that nitrate mobilizes naturally occurring U from aquifer sediments has not been presented. Here, we demonstrate that the influx of high-nitrate porewater through High Plains alluvial aquifer silt sediments bearing naturally occurring U(IV) can stimulate a nitrate-reducing microbial community capable of catalyzing the oxidation and mobilization …

Data clustering is used in multiple fields, including health, finance, social networks, education, and science. Sequential processing of clustering algorithms, like the K-Means, Minibatch K-Means, …

Establishing Roots Before Branching Out: Parameter Recovery In Item Response Tree Models, Tyler Ryan

Browse all Theses and Dissertations

Item Response Trees are a type of item response model that incorporates information about conditional responding to items using a rooted tree graph structure. Researchers have used item response trees for common measurement tasks and for testing novel hypotheses. Previous simulation studies investigating item response trees either lack generalizability to the broad domain of their use or lack thorough investigation and reporting of the results. I conducted a simulation study to explore how sample size, test length, item characteristics, and tree structure affect both item and person parameter recovery for 1PL and 2PL models. The results suggested that, as with …

Rankine Cycle Investigation On Meeting Power And Thermal Requirements Of High-Speed Aircraft, Jacob J. Spark

Browse all Theses and Dissertations

This work is investigating a dual mode Rankine cycle for aircraft applications, specifically meeting vehicle thermal and power requirements. This multiconfigurational approach allows the Thermal Management System (TMS) to be controlled based on aircraft needs. In this design, waste heat is removed from critical areas of the aircraft (e.g., propulsion, structure, subsystems) using the fuel as a heat sink. Hot fuel is then forced through a heat exchanger actively boiling water. The vapor byproduct is fed to a turbine coupled to a generator, providing power. The low-pressure steam is then condensed using cold fuel drawn from its tank; however, when …
