Creating A Virtual Reality Experience In Service To A Non-Profit Agency, Frank Deese, Susan Lakin, Isabelle Anderson

Frameless

In the summer of 2018, RIT Professors Susan Lakin and Frank Deese discussed with the principal officers of the Society for the Protection and Care of Children (SPCC) in Rochester how the new technology of Virtual Reality might be used to not only impart information to viewers, but generate empathy for those receiving services from the organization as well as those performing those services. Their ultimate goal was to create an experience that could be viewed with VR headsets at fundraising events and on a website using low-cost Google Cardboard.

Can We Walk In Our Patients’ Shoes? Immersive Virtual Reality As An Empathy Training Tool For Medical Students, Riham Alieldin, Raffaella Borasi, Anne Nofziger, Karen Deangelis, Sarah Peyre

Frameless

Empathy is arguably the “backbone” of the patient-physician relationship. It has been shown to have numerous positive clinical outcomes especially in a patient-centered careservice. Nevertheless, studies have shown a disintegration of empathy and compassion in physicians during medical school and residency training due to the lack of standardization of empathy training in medical education.

A Review Of Xr Classrooms In Institutions Of Higher Education, Brandon Patterson, Tallie Casucci

Frameless

This talk will review the literature and examine existing physical spaces using virtual reality (VR) and augmented reality (AR), often referred together as extended reality (XR), to teach learners in an academic setting. Attendees will better understand best practices and ways of addressing potential challenges when designing a physical XR classroom space for higher education. A physical XR classroom provides institutions with a dedicated space for educational courses and workshops, which utilize XR for both one- off sessions and an entire semester (Pirker, Holly, and Gütl 2020). The talk will help answer the question, why a dedicated XR classroom?

Applied Math In Introductory Chemistry, Ji Kim, Grace Pai

Open Educational Resources

Students, particularly those who are non-science majors, often struggle with college-level science courses required for graduation due to the applied mathematics needed to successfully complete the course. This resource includes four activities on the topics of units and measurements, dimensional analysis, density, and gases. These topics were specifically designed to teach the mathematics embedded in these topics in a culturally responsive way. Throughout the activities, we incorporate these four elements of culturally relevant pedagogy (Ladson-Billings, 2009) in order to engage students in successfully solving basic mathematics in chemistry while promoting their interest in learning chemistry.

H-Atom And O-Atom Methods: From Balancing Redox Reactions To Determining The Number Of Transferred Electrons, Pong Yuen, Cheng Man Diana Lau

Faculty Publications

Defining and balancing redox reaction requires both chemical knowledge and mathematical skills. The prevalent approach is to use the concept of oxidation number to determine the number of transferred electrons. However, the task of calculating oxidation numbers is often challenging. In this article, the H-atom method and O-atom method are developed for balancing redox equations. These two methods are based on the definition of redox reaction, which is the gain and loss of hydrogen or oxygen atoms. They complement current practices and provide an alternate path to balance redox equations. The advantage of these methods is that calculation of oxidation …

How Failures Cascade In Software Systems, Barbara W. Chamberlin

Theses and Dissertations

Cascading failures involve a failure in one system component that triggers failures in successive system components, potentially leading to system wide failures. While frequently used fault tolerant techniques can reduce the severity and the frequency of such failures, they continue to occur in practice. To better understand how failures cascade, we have conducted a qualitative analysis of 55 cascading failures, described in 26 publicly available incident reports. Through this analysis we have identified 16 types of cascading mechanisms (organized into eight categories) that capture the nature of the system interactions that contribute to cascading failures. We also discuss three themes …

The Perception Of At-Risk Students On Caring Student-Teacher Relationships And Its Impact On Their Productive Disposition, Brittany Hopper

Theses and Dissertations

The importance of a positive, caring relationship with students in the classroom is under-researched in mathematics education. Research shows that a positive student-teacher relationship can have many long-term positive results for the student. Many of these results directly impact a student's productive disposition towards mathematics. At-risk students are in greater need of positive relationships and an increase in productive disposition. Using Joan Tronto's (1993) elements of care, I examine the student perspective of these kinds of relationships and how the student sees development of their own productive disposition.

Accurate Band Energies Of Metals With Quadratic Integration, Jeremy John Jorgensen

Theses and Dissertations

Materials play an important role in society. Historically, and even at present, materials have been discovered by trial and error, and many of the most useful materials have been discovered by chance. The high-throughput approach aims to remove (as much as possible) chance and guesswork at the experimental level by filtering out materials candidates that are not predicted to exist. Many successes have been recorded. In the high-throughput approach to materials discovery, machined-learned models of materials are created from databases of theoretical materials. These databases are the result of millions of density-functional-theory (DFT) simulations. The size and accuracy of the …

Tuning Properties Of Topological Insulators: An Ab-Initio Approach, Karunya Shailesh Shirali

LSU Doctoral Dissertations

This thesis develops a first-principles based approach to explore the tuning of topological properties of the tetradymite topological insulators. We begin by setting up a framework to systematically obtain the bulk and surface properties of topological insulators, treating the structural and electronic properties on an equal footing. We determine a consistent method for including the van der Waals interactions, which are responsible for the weak coupling between sets of atomic layers in this family of layered materials, which is important in obtaining accurate structural properties. We obtain close agreement with experimental values for both the bulk and surface states.

Sandworms And Computer Worms: An Assessment Of American Critical Infrastructure Cyber Vulnerabilities And The Russian Federation's Growing Offensive Capabilities, Spencer Johns

Honors Theses

Bottom Line Up Front: It is highly likely that the Russian GRU has the capability, resources, and intent to execute cyberweapon attacks against American critical infrastructure in times of heightened tensions, either as a warning or a first strike. I also assess that much of current American critical infrastructure is not secure enough to withstand a coordinated assault by the GRU, and very likely has numerous severe vulnerabilities known by the GRU.

Performance Improvements In Inner Product Encryption, Serena Riback

Honors Scholar Theses

Consider a database that contains thousands of entries of the iris biometric. Each entry identifies an individual, so it is especially important that it remains secure. However, searching for entries among an encrypted database proves to be a security problem - how should one search encrypted data without leaking any information to a potential attacker? The proximity searchable encryption scheme, as discussed in the work by Cachet et al., uses the notions of inner product encryption developed by Kim et al.. In this paper, we will focus on the efficiency of these schemes. Specifically, how the symmetry of the bilinear …

A Multidimensional Convolutional Bootstrapping Method For The Analysis Of Degradation Data, Jared M. Clark

Theses and Dissertations

While Monte Carlo methods for bootstrapping are typically easy to implement, they can be quite time intensive. This work aims to extend an established convolutional method of bootstrapping to work when convolutions in two or more dimensions are required. The convolutional method relies on efficient computational tools rather than Monte Carlo simulation which can greatly reduce the computation time. The proposed method is particularly well suited for the analysis of degradation data when the data are not collected on time intervals of equal length. The convolutional bootstrapping method is typically much faster than the Monte Carlo bootstrap and can be …

A Permutation-Based Confidence Distribution For Rare-Event Meta-Analysis, Travis Andersen

Theses and Dissertations

Confidence distributions (CDs), which provide evidence across all levels of significance, are receiving increasing attention, especially in meta-analysis. Meta-analyses allow independent study results to be combined to produce one overall conclusion and are particularly useful in public health and medicine. For studies with binary outcomes that are rare, many traditional meta-analysis methods often fail (Sutton et al. 2002; Efthimiou 2018; Liu et al. 2018; Liu 2019; Hunter and Schmidt 2000; Kontopantelis et al. 2013). Zabriskie et al. (2021b) develop a permutation-based method to analyze such data when study treatment effects vary beyond what is expected by chance. In this work, …

Trout Responses To Stocking Rates And River Discharge Within A Southeastern U.S. Hydropeaking Tailwater, Jonathan J. Spurgeon, Joseph Kaiser, Christy Graham, Steve Lochmann

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Freshwater fish populations often exist in systems characterized by novel ecological processes resulting from human alteration. Salmonid populations embedded within coldwater sections of warmwater rivers are spatially constrained by habitat availability. Tailwater fish contend with fluctuating river discharges and density-dependent processes associated with fish stocking and exploitation. Salmonid populations sustained through stocking versus natural reproduction may respond differently to changes in hydrologic patterns (e.g., hydropeaking) as well as declines in fish abundance. We assessed differences between stocked (Rainbow Trout Oncorhynchus mykiss) and naturalized (Brown Trout Salmo trutta) trout populations in Greers Ferry tailwater, Arkansas, regarding (1) spatial and …

Visual Attention Methods In Deep Learning: An In-Depth Survey, Mohammed Hassanin, Anwar Saeed, Ibrahim Radwan, Fahad Shahbaz Khan, Ajmal Mian

Computer Vision Faculty Publications

Inspired by the human cognitive system, attention is a mechanism that imitates the human cognitive awareness about specific information, amplifying critical details to focus more on the essential aspects of data. Deep learning has employed attention to boost performance for many applications. Interestingly, the same attention design can suit processing different data modalities and can easily be incorporated into large networks. Furthermore, multiple complementary attention mechanisms can be incorporated in one network. Hence, attention techniques have become extremely attractive. However, the literature lacks a comprehensive survey specific to attention techniques to guide researchers in employing attention in their deep models. …

Modeling Air Pressure Propagation Through Wind Cave And Jewel Cave: How Can Air Pressure Signals Inside Barometric Caves Be Predicted From Surface Pressure Measurements?, Annika K. Gomell, Andreas Pflitsch

International Journal of Speleology

Recent speleoclimatological research has shed new light on air pressure dynamics inside barometric caves by identifying pressure-modifying processes and resulting systematic differences between cave and surface air pressure. Based on these new findings, a multi- step quantitative model is developed and explored to predict air pressure inside Wind Cave and Jewel Cave – two major barometric cave systems in the Black Hills of South Dakota, USA – from external surface measurements. Therefore, each identified speleoclimatological pressure process is translated into a mathematical operation. Model evaluation based on Pearson correlation and mean (absolute) deviation between model outputs and control measurements yields …

We investigated the effect of the phenyl spacer on the azaborine unit. The substituent effects of different electronic moieties were investigated by the insertion of electron –withdrawing and –donating moieties to the phenyl spacer. We examined the role of the electron –donating …

Gravimetric Determination Of The Adsorption Capacity Of Zirconium Hydroxide For Isopropanol, Riley Bennett

Symposium of Student Scholars

Zirconium hydroxide’s adsorption properties make it useful for the decomposition of chemical warfare agents and toxic industrial chemicals. In the current study, isopropanol is used to examine the adsorption behavior of the zirconium hydroxide surface sites through a series of microreactor experiments. Initially, the mass delivery of isopropanol is calibrated as a function of temperature and gas flow rate. Separate experiments can then be done by flowing the isopropanol mixture through a sample of zirconium hydroxide to quantitatively determine the amount of isopropanol that can adsorb onto a sample of zirconium hydroxide. FT-IR spectra of the gas mixtures flowing from …

The Investigation Of Geologically Relevant Metal Phosphites As A Plausible Source Of Phosphorus In Prebiotic Chemistry, James Quarles, Amelia Shengaout, Kimberly Meyberg, Heather Abbott-Lyon

Symposium of Student Scholars

To understand the origin of life, the abiotic incorporation of phosphorus in energy-promoting molecules like adenosine triphosphate (ATP) need to be identified. However, a consensus has not been reached on the source of phosphorus for prebiotic chemistry on Archaean Earth. One hypothesis is that metal phosphites were an important source of phosphorus for prebiotic chemistry. The primary issue with this hypothesis is the lack of phosphites in the geological rock record, where different phosphorus compounds (mostly inorganic phosphates) are observed instead. Two geologically relevant metal phosphites with varying waters of hydration, CaHPO3 and MgHPO3, were synthesized, structurally characterized, and thermally …

Finding cost-effective novel technology for storing and sharing student's credentials among academic institutions and potential employers is a demand. Within the current conventional approach, ensuring authentication of a candidate’s credentials is costly and time-consuming which gives burdens to thousands of prospective students and potential employees. As a result, candidates fail to secure opportunities for either delay or non-submission of credentials all over the world. Blockchain technology has the potential for students' control over their credentials; …

Synthesis And Characterization Of Chiral Magnetic Oxide: Mnmoteo6, Chase Hames, August Meads

Symposium of Student Scholars

The chiral materials lack mirror reflection symmetry in their crystal structures like right and left hands. Such materials often host unique non-collinear or topological magnetic textures such as magnetic skyrmions. If such magnetic textures are formed in insulating oxides with coupled electric and magnetic properties, then such magnetic structures can be controlled and manipulated using electric fields rather than electric current. With this motivation, we are synthesizing and characterizing chiral materials belonging to MMoTeO₆ (M=Mn, Co, Fe, Cu, Ni) family. I will discuss about the phase formation and solid-state synthesis of MnTeMoO₆ along with its structural, electrical and …
