Impactful Interactivity Within Video Games, Luke Robert Maeser

Theses

Despite half a century of existence and dedicated academic programs educating next generations of game developers, conclusive evidence does not exist as to if video games are beneficial to learning or costly. Examining the notion of benefit versus cost, it is important to assess the value of video games when leveraged as tools for learning as traditional educational methodologies are not infallible. This paper explores how video games can generate psychological responses; and therefore, one must conclude learning has occurred. The following is encompassed: meaningful interactivity within video games (regarding narrative and gameplay), video games as educational tools, video game …

Static Binary Rewriting For Rop Gadget Removal, Hans Verhoeven

Masters Theses & Doctoral Dissertations

Return-Oriented Programming (ROP) is an exploitation technique that is commonly used by malicious users. It works by leveraging return statements in binaries to gain control over the execution of programs. Some mitigations for ROP include changing the binary during compilation time, rewriting the binary after compilation, and adding runtime checks to the binary. The focus of this study was rewriting the binary after compilation. Rewriting during compilation time requires end users to have access to source code, which, in most cases, they will not. Adding runtime checks adds additional overhead to the target binary.

The areas this study aimed to …

Investigating Programmer Bias Transfer To Computer Tasks Among Hispanic Csci/Cmpe Students In A Minority-Serving Institution, Ana Cecilia Sánchez Ramos

Theses and Dissertations

Algorithm-driven systems are increasingly being used across a variety of settings (Center for Democracy and Technology, 2020; O’Neil, 2017; Sauppé and Mutlu, 2015). However, many everyday technologies are imbued with racial biases that unfairly discriminate against racially marginalized groups (Hankerson et al, 2016; Crawford, 2016; O’Neil, 2017). While sources of bias like the unintended overrepresentation of elements in an algorithm’s dataset have been well researched (Hankerson et. al, 2016; Lee, 2015), the transfer of personal prejudices onto a system remains understudied. Here I address this issue and draw from Sociological literature on organizational theory, assimilation, and colorblind ideology to develop …

Faculty Research, Scholarly, and Creative Activity

Accidental patient harms occur frequently in healthcare, but their exact prevalence and interventions that will best prevent them are still poorly understood. In rare cases, healthcare providers who have contributed to accidental patient harm may be criminally prosecuted to obtain justice for the patient and family or to set an example, which theoretically prevents other providers from making similar mistakes due to fear of punishment. A recent case where this strategy was chosen is the RaDonda L. Vaught vs. Tennessee (2022) criminal case. The present article discusses this case and its ramifications, as well as provides concrete recommendations for actions …

Experimental Analysis Of Nonlinear Wave Propagation In Bistable Mechanical Metamaterials With A Defect, Samuel R. Harre

Department of Mechanical and Materials Engineering: Dissertations, Theses, and Student Research

Mechanical metamaterials built up of compliant units can support the propagation of linear and nonlinear waves. A popular architecture consists of a one-dimensional chain of bistable elements connected by linear springs. This type of chain can support nonlinear transition waves that switch each element from one stable state to the other as they propagate along the chain. One way to manipulate the propagation of such waves is via introduction of a local inhomogeneity, i.e., a defect in the otherwise periodic chain. Recent analytical and numerical work has shown that based on its initial velocity, a transition wave may be reflected, …

On Dyadic Parity Check Codes And Their Generalizations, Meraiah Martinez

Department of Mathematics: Dissertations, Theses, and Student Research

In order to communicate information over a noisy channel, error-correcting codes can be used to ensure that small errors don’t prevent the transmission of a message. One family of codes that has been found to have good properties is low-density parity check (LDPC) codes. These are represented by sparse bipartite graphs and have low complexity graph-based decoding algorithms. Various graphical properties, such as the girth and stopping sets, influence when these algorithms might fail. Additionally, codes based on algebraically structured parity check matrices are desirable in applications due to their compact representations, practical implementation advantages, and tractable decoder performance analysis. …
