Modeling Distances Between Various Attractions And Nearest City Parks Using Exponential Distribution, Ashley Hall
Modeling Distances Between Various Attractions And Nearest City Parks Using Exponential Distribution, Ashley Hall
Scholars Week
We examine the park data in Twin Cities Metropolitan Area (TCMA) to understand the distances between various attractions (water features, transit stops, bike paths, sport fields, etc.) and nearest city parks. We verify our research hypothesis that these distance variables are exponentially distributed using histograms and chi-squared goodness-of-fit test. Our findings suggest that most of the distance variables are indeed exponentially distributed except the one that measures the distance between the metropolitan area and the nearest city parks. Based on that, we further hypothesize that the locations of the various attractions relative to the nearest city parks follow the spatial …
Polycarbodiimides And Polyguanidines : Their Reactivity And Applications In Covalent Adaptable Networks, Alberto Melchor Bañales
Polycarbodiimides And Polyguanidines : Their Reactivity And Applications In Covalent Adaptable Networks, Alberto Melchor Bañales
Scholars Week
We have recently discovered a new chemical transformation in which N,N’,N’’ tri-substituted guanidines undergo a thermal exchange reaction. Kinetic investigations indicate that the transformation is first order with respect to the guanidine, indicating a dissociative mechanism in which a carbodiimide and amine are formed as intermediates. This new reaction has been applied to polymer systems. Polycarbodiimides were shown to undergo postpolymerization modification with amines to form polyguanidines at room temperature under an hour. Polyguanidines undergo the newly found chemical transformation to form different substituted polyguanidines. This exchange reaction will be applied to the preparation of a covalent adaptable network by …

Some of these problems can be CPR training, etc. Used as an evaluation platform of suggested hardware to get a desired (or best fit) set of smart objects, or combinations with computer vision. Cost model to determine best fit based on: accuracy, lowest cost, easiest deployment, etc.
Vibrations On Networks, Zachary Pontrantolfi
Vibrations On Networks, Zachary Pontrantolfi
Scholars Week
Studying vibrations on networks helps inform our understanding of random processes on other networks with similar geometry. We discuss two physical models to build up intuition about their eigenvectors. We conclude with a hidden connection between the rate of convergence of random walks, and the ground state energies of molecules.
Performance Annotation Framework, Quentin Jensen, Chloe Dawson
Performance Annotation Framework, Quentin Jensen, Chloe Dawson
Scholars Week
Large scale applications developers have many tools at their disposal to optimize and verify their software. One of which is Caliper, an annotation-based performance measurement tool. Caliper is very powerful and versatile, however, can be cumbersome to apply to complex applications. To solve this problem, we have created a framework to automatically prepare an application for performance measurement. This framework provides a layer of abstraction between the user and the source-code annotations and library linking. As a result, the process of measuring the performance of an application can be fully automated away – a huge step towards automatic software optimization.
Resources For Interdisciplinary Understanding Of Energy, Alessandra Hughes, Jessica Trottier
Resources For Interdisciplinary Understanding Of Energy, Alessandra Hughes, Jessica Trottier
Scholars Week
In most undergraduate curricula, students are expected to have the ability to apply, or transfer, a learned concept to new coursework. In the sciences, students are often introduced to energy ideas with discipline-specific vocabulary and tasks which encourage compartmentalized, surface-level understandings of energy concepts. Our research investigates student transfer of energy ideas within a coherent science course series, where physics is the foundational course. Similar modeling tools and vocabulary are used in the classes to help students see energy as a unifying framework. We seek to identify and describe what transfer “looks like” in this idealized context by interviewing students …

Spectral Analysis Of Stratigraphy At Eberswalde Crater, Mars, Cory Hughes
Scholars Week
We will analyze spectral characteristics of stratigraphy in the catchment and deposit at Eberswalde Crater, Mars. This crater is a frequent contender for the preferred destination of future Mars rover and human science missions in the search for evidence of life on the Red Planet.
Strategy Flexibility: Choosing Different Systems To Apply The Work Energy Principle, Grace Baker, Thanh Le
Strategy Flexibility: Choosing Different Systems To Apply The Work Energy Principle, Grace Baker, Thanh Le
Scholars Week
An important goal of physics instruction is to help students become adaptive problem solvers so that they can approach a wide range of situations. One aspect of adaptive problem solving is strategy flexibility — knowing multiple ways to approach a problem and choosing the most appropriate approach. In this study, we examine the role of meta strategic judgements in students’ application of strategy flexibility. Specifically, we study students’ meta-strategic judgements when choosing a system with which to apply the work-energy principle to various scenarios. College students enrolled in an introductory mechanics course were interviewed about their rationales for their system …
Engineering Sortase; Activity And Selectivity Of New Hybrid And Ancestral Variants Of Sortase A, Sarah Struyvenberg
Engineering Sortase; Activity And Selectivity Of New Hybrid And Ancestral Variants Of Sortase A, Sarah Struyvenberg
Scholars Week
Bacterial sortase enzymes are a beneficial tool in innovative mechanisms of protein engineering. However, important limitations to utilization of sortases for engineered purposes exist; namely, that sortase A (SrtA) is a relatively poor enzyme and very specific for the substrate containing LPATXG motif. Exciting previous work from our collaborators reveals that sortases from different species recognize different sequences and that activity can vary. Therefore, we wanted to create and investigate hybrid sortase enzymes between SrtA from S. aureus and Streptococcus pneumoniae, wherein we swapped a substrate-interacting loop between the beta-E and beta-F strands. Our hypothesis is that these residues are …
A Quantitative Assessment Of The Diabetes Self-Management Education Program, Grace Mcfarlane
A Quantitative Assessment Of The Diabetes Self-Management Education Program, Grace Mcfarlane
Scholars Week
A Diabetes Self-Management Education (DSME) program offered in an inner-city health center run by the Cincinnati Health Department, which started in 2014, was created to help those in an underserved population learn how to manage their diabetes. Two key measurements, A1C (glycated hemoglobin) and BMI (body mass index), were taken over time to monitor their progress. In this study, we analyzed quantitatively whether or not there was a significant improvement in their BMI and A1C values over the course of two years since they joined DSME program as any improvement would imply a potentially healthier lifestyle in regards to their …
A Simulation Platform For Generation Of Synthetic Videos For Human Activity Recognition, Gary Plunkett
A Simulation Platform For Generation Of Synthetic Videos For Human Activity Recognition, Gary Plunkett
Scholars Week
The field of human activity recognition from video data has recently made great strides. However, the large amount of labelled data needed to train activity recognition models remains a common bottleneck. We introduce a simulation platform to procedurally generate synthetic videos of household activities, which randomizes portions of the virtual scene like camera position, human model, and interaction motion to introduce video variation.

An Automated Spectrogoniometer System With Planetary Science Applications, Kathleen Hoza
Scholars Week
Reflectance spectroscopy is a major technique for characterizing the composition of planetary surfaces, and has led to key findings such as the characterization of alteration minerals indicative of an aqueous, neutral-pH environment in Mars’ past. When a reflectance spectrometer collects data, it does so at some viewing geometry, which is defined by the angular relationships between the light source illuminating the surface, the target material, and the detector. In the lab, this is usually at a standard viewing geometry (e.g. incidence=0, emission=30). In situ measurements taken by spacecraft, however, may be taken at a wide range of viewing geometries. This …

A Day In The Life Of A Supercomputer, William Clem, Sean Mcculloch
Scholars Week
We are developing an interactive dashboard for visualizing the statistics of how users interact with nodes of a supercomputer. The intended purpose of the dashboard is to periodically provide with the overview of the load and bandwidth utilization of the nodes of a large supercomputer and details of each node and job as selected by the user. The dashboard will be interactive which will enable users to zoom in on interesting parts of the visualizations to investigate in details.
Bottom-Up Shape Engineering Of Organic Molecular Single-Crystals, Griffin Reed
Bottom-Up Shape Engineering Of Organic Molecular Single-Crystals, Griffin Reed
Scholars Week
The ability to fabricate complex submicron-scale components from inorganic crystalline semiconductor materials such as c-Si enables countless modern technologies, from microelectromechanical systems to integrated circuits. For single-crystal molecular materials on the other hand, comparable approaches to defining micron- and submicron-scale structure are much less well developed, in part because weak intermolecular binding forces make molecular crystals vulnerable to damage by conventional techniques such as reactive ion etching, wet etching, and energetic beam milling. Here we show how the same weak forces that are problematic for top-down patterning of molecular crystals can be exploited to enable controlled bottom-up growth, by leveraging …
