Description
This Creative Project was carried out in coordination with the capstone project, Around the Corner Imaging with Terahertz Waves. This capstone project deals with a system designed to implement Around the Corner, or Non Line-of-Sight (NLoS) Imaging. This document discusses the creation of a GUI using MATLAB to control the Terahertz Imaging system. The GUI was developed in response to a need for synchronization, ease of operation, easy parameter modification, and data management. Along the way, many design decisions were made ranging from choosing a software platform to determining how variables should be passed. These decisions and considerations are discussed in this document. The resulting GUI has measured up to the design criteria and will be able to be used by anyone wishing to use the Terahertz Imaging System for further research in the field of Around the Corner or NLoS Imaging.

Description
The purpose of this thesis is to study the issue of animal agriculture and why people chose to consume sentient beings such as pigs, chickens, and cows yet house equally as sentient and intelligent beings such as dogs and cats. I want to understand people’s reasoning and logic behind discriminating who they love versus who they eat. This thesis intends to help readers become more aware of the cognitive dissonance behind the food choices that most Americans make up to three times a day. Data was collected through Google Form surveys for freshman living in the dorms at Barrett, The Honors College. The results showed that animal intelligence did not factor in people’s decision to consume their parts. Additionally, this study concluded that participants are more likely to feel less guilty when they are under the false belief that the meat they purchased was mislabeled with terms such as ‘humane slaughter.’

Description
As urban populations increase, so does the demand for innovative transportation solutions which reduce traffic congestion, reduce pollution, and reduce inequalities by providing mobility for all kinds of people. One emerging solution is self-driving vehicles, which have been coined as a safer driving method by reducing fatalities due to driving accidents. While completely automated vehicles are still in the testing and development phase, the United Nations predict their full debut by 2030 [1]. While many resources are focusing their time on creating the technology to execute decisions such as the controls, communications, and sensing, engineers often leave ethics as an afterthought. The truth is autonomous vehicles are imperfect systems that will still experience possible crash scenarios even if all systems are working perfectly. Because of this, ethical machine learning must be considered and implemented to avoid an ethical catastrophe which could delay or completely halt future autonomous vehicle development. This paper presents an experiment for determining a more complete view of human morality and how this translates into ideal driving behaviors.
This paper analyzes responses to deviated Trolley Problem scenarios [5] in a simulated driving environment and still images from MIT’s moral machine website [8] to better understand how humans respond to various crashes. Also included is participants driving habits and personal values, however the bulk of that analysis is not included here. The results of the simulation prove that for the most part in driving scenarios, people would rather sacrifice themselves over people outside of the vehicle. The moral machine scenarios prove that self-sacrifice changes as the trend to harm one’s own vehicle was not so strong when passengers were introduced. Further defending this idea is the importance placed on Family Security over any other value.
Suggestions for implementing ethics into autonomous vehicle crashes stem from the results of this experiment but are dependent on more research and greater sample sizes. Once enough data is collected and analyzed, a moral baseline for human’s moral domain may be agreed upon, quantified, and turned into hard rules governing how self-driving cars should act in different scenarios. With these hard rules as boundary conditions, artificial intelligence should provide training and incremental learning for scenarios which cannot be determined by the rules. Finally, the neural networks which make decisions in artificial intelligence must move from their current “black box” state to something more traceable. This will allow researchers to understand why an autonomous vehicle made a certain decision and allow tweaks as needed.

Description
The objective of this paper is to find and describe trends in the fast Fourier transformed accelerometer data that can be used to predict the mechanical failure of large vacuum pumps used in industrial settings, such as providing drinking water. Using three-dimensional plots of the data, this paper suggests how a model can be developed to predict the mechanical failure of vacuum pumps.

Description
In vitro gametogenesis (IVG) research has been growing in countries like Japan, US, and China after the development of stem cell research and other scientific advancements as well as because of the perception of infertility as a domestic and international problem. IVG research’s progress has been deliberated internationally, with discussion of questions, challenges, and possibilities that have arisen and may arise in the future as the technology is adopted by different countries. The first section introduces the meaning of IVG, explains the importance of review by scientists and citizens for IVG, and describes a rise in infertility reported in multiple developed countries that could be addressed by IVG. The second section discusses IVG’s applications and implications using 5 ethical categories articulated by Obama’s Presidential Commission for the Study of Bioethical Issues: Public Beneficence, Responsible Stewardship, Intellectual Freedom and Responsibility, Democratic Deliberation, and Justice and Fairness. These five ethical principles were intended for analysis of emerging technologies, and IVG is an emerging technology with possible integration into clinical settings. Among the principles, it seemed that a major weak point of inquiry concerns LGBT+ and disability inclusion, especially of gender dysphoric and transgender people who may experience higher rates of infertility and have a harder time conceiving due to a mix of discrimination, gender dysphoria, and infertility due to hormone replacement therapy (HRT) treatment or gender/sex reassignment surgeries (GRSs/SRSs) that may impair or remove reproductive body parts. A number of other ethical considerations arise about this technology.

Whistleblowing in Biomedical Research and Medicine: An Analysis of Ethical Expectations and Dilemmas
Description
In biomedical research institutions and medical institutions alike, whistleblowing, or the reporting of misconduct, has been severely retaliated against. Whistleblowers report misconduct by adhering to institutional whistleblowing policies, and do so in order to maintain ethical practice within their institution; it is important to note that by taking this ethical action, whistleblowers are aiming to protect the future of biomedical research and medicine. Despite these intentions, whistleblowing has developed a negative stigma due to the misconception that whistleblowers have self-proclaimed authority and are unable to function as part of a team. The retaliation against whistleblowers has been connected to psychological and professional fallout for the whistleblower, and it has been found that many whistleblowers suffer as a direct result of a lack of institutional support. The problems with whistleblowing culture demonstrate issues surrounding how ethics are maintained in institutions, who ethics policies apply to, and who has authority. The retaliation seen against whistleblowers outlines inherent institutional failures, and highlights the need for institutional change in order to both promote ethical practice and protect the whistleblowers who adhere to ethics policies. This thesis discusses such failures in detail, and outlines several broad solutions in order to combat this issue.

Description
Power spectral analysis is a fundamental aspect of signal processing used in the detection and \\estimation of various signal features. Signals spaced closely in frequency are problematic and lead analysts to miss crucial details surrounding the data. The Capon and Bartlett methods are non-parametric filterbank approaches to power spectrum estimation. The Capon algorithm is known as the "adaptive" approach to power spectrum estimation because its filter impulse responses are adapted to fit the characteristics of the data. The Bartlett method is known as the "conventional" approach to power spectrum estimation (PSE) and has a fixed deterministic filter. Both techniques rely on the Sample Covariance Matrix (SCM). The first objective of this project is to analyze the origins and characteristics of the Capon and Bartlett methods to understand their abilities to resolve signals closely spaced in frequency. Taking into consideration the Capon and Bartlett's reliance on the SCM, there is a novelty in combining these two algorithms using their cross-coherence. The second objective of this project is to analyze the performance of the Capon-Bartlett Cross Spectra. This study will involve Matlab simulations of known test cases and comparisons with approximate theoretical predictions.

Description
Complex human controls is a topic of much interest in the fields of robotics, manufacturing, space exploration and many others. Even simple tasks that humans perform with ease can be extremely complicated when observed from a controls and complex systems perspective. One such simple task is that of a human carrying and moving a coffee cup. Though this may be a mundane task for humans, when this task is modelled and analyzed, the system may be quite chaotic in nature. Understanding such systems is key to the development robots and autonomous systems that can perform these tasks themselves.
The coffee cup system can be simplified and modeled by a cart-and-pendulum system. Bazzi et al. and Maurice et al. present two different cart-and-pendulum systems to represent the coffee cup system [1],[2]. The purpose of this project was to build upon these systems and to gain a better understanding of the coffee cup system and to determine where chaos existed within the system. The honors thesis team first worked with their senior design group to develop a mathematical model for the cart-and-pendulum system based on the Bazzi and Maurice papers [1],[2]. This system was analyzed and then built upon by the honors thesis team to build a cart-and-two-pendulum model to represent the coffee cup system more accurately.
Analysis of the single pendulum model showed that there exists a low frequency region where the pendulum and the cart remain in phase with each other and a high frequency region where the cart and pendulum have a π phase difference between them. The transition point of the low and high frequency region is determined by the resonant frequency of the pendulum. The analysis of the two-pendulum system also confirmed this result and revealed that differences in length between the pendulum cause the pendulums to transition to the high frequency regions at separate frequency. The pendulums have different resonance frequencies and transition into the high frequency region based on their own resonant frequency. This causes a range of frequencies where the pendulums are out of phase from each other. After both pendulums have transitioned, they remain in phase with each other and out of phase from the cart.
However, if the length of the pendulum is decreased too much, the system starts to exhibit chaotic behavior. The short pendulum starts to act in a chaotic manner and the phase relationship between the pendulums and the carts is no longer maintained. Since the pendulum length represents the distance between the particle of coffee and the top of the cup, this implies that coffee near the top of the cup would cause the system to act chaotically. Further analysis would be needed to determine the reason why the length affects the system in this way.

Description
The Centralia Council, representative of a small Pennsylvania borough, arranged for an illegal controlled burn of the Centralia landfill in late May 1962. It happened the same way every year. As Memorial Day drew closer, the Council contracted volunteer firefighters to burn the top layer of refuse in the landfill in preparation for the day’s festivities, but intentionally burning landfills violated state law. A tangle of events over the years saw the “controlled” burn develop into an underground mine fire and then into a coal seam fire. Excavation costs lie far beyond the state’s budget, and Pennsylvania plans to let the fire burn until its natural end--anticipated at another 240 years. The tangled mess of poor decisions over 21 years begs one question: did the people or the fire kill Centralia?
This paper’s field of study falls into the cross section of geology and fire science, history, social conflict, public service ethics, and collaborative failures. I explore how a series of small choices snowballed into a full, government funded relocation effort after attempts at controlling the anthracite coal seam fire failed. Geology and fire science worked in tandem during the mine fire, influencing each other and complicating the firefighting efforts. The fire itself was a unique challenge. The history of Centralia played a large role in the government and community response efforts. I use the borough and regional history to contextualize the social conflict that divided Centralia. Social conflict impaired the community’s ability to unify and form a therapeutic community, and in turn, it damaged community-government relationships. The government agencies involved in the mine fire response did their own damage to community relationships by pursuing their own interests. Agencies worried about their brand image, and politicians worried about re-election. I study how these ethical failures impacted the situation. Finally, I look at a few examples of collaborative failures on behalf of the government and the community. Over the course of my research, it became apparent the people killed Centralia, not the fire.

Description
In the past several years, the long-standing debate over freedom and responsibility has been applied to artificial intelligence (AI). Some such as Raul Hakli and Pekka Makela argue that no matter how complex robotics becomes, it is impossible for any robot to become a morally responsible agent. Hakli and Makela assert that even if robots become complex enough that they possess all the capacities required for moral responsibility, their history of being programmed undermines the robot’s autonomy in a responsibility-undermining way. In this paper, I argue that a robot’s history of being programmed does not undermine that robot’s autonomy in a responsibility-undermining way. I begin the paper with an introduction to Raul and Hakli’s argument, as well as an introduction to several case studies that will be utilized to explain my argument throughout the paper. I then display why Hakli and Makela’s argument is a compelling case against robots being able to be morally responsible agents. Next, I extract Hakli and Makela’s argument and explain it thoroughly. I then present my counterargument and explain why it is a counterexample to that of Hakli and Makela’s.
