A Performance Survey Of Text-Based Sentiment Analysis Methods For Automating Usability Evaluations, Kelsi Van Damme

Master's Theses

Usability testing, or user experience (UX) testing, is increasingly recognized as an important part of the user interface design process. However, evaluating usability tests can be expensive in terms of time and resources and can lack consistency between human evaluators. This makes automation an appealing expansion or alternative to conventional usability techniques.

Early usability automation focused on evaluating human behavior through quantitative metrics but the explosion of opinion mining and sentiment analysis applications in recent decades has led to exciting new possibilities for usability evaluation methods.

This paper presents a survey of modern, open-source sentiment analyzers’ usefulness in extracting and …

Analytical, Numerical, And Computational Methods To Analyze The Time To Empty Open, Closed, And Variable-Topped Inverted Bottles, Callen Schwefler

Master's Theses

Recent unexpected experimental observations of the emptying of inverted bottles with perforations has generated interest in modeling and simulation of this phenomenon. It was observed that as a perforation, i.e., a small hole at the "top" of the inverted bottle, is added and enlarged, the overall emptying time first increases to a maximum value and then decreases until it reaches a lower limit. The change in emptying time is associated with a transition from jetting, where only water exits the neck, to glugging, a competition between air and water flows at the neck of the bottle.

This paper develops analytical …

Perishable Food Waste Reduction Through Technological Implementation At The Retail Level Of The Food Supply Chain, Cassandra Harriman

Master's Theses

No prior research had considered the primary goal of reducing food waste while preserving retailer profit through technological implementation. This paper quantifies the effects …

Dependencyvis: Helping Developers Visualize Software Dependency Information, Nathan Lui

Master's Theses

The use of dependencies have been increasing in popularity over the past decade, especially as package managers such as JavaScript's npm has made getting these packages a simple command to run. However, while incidents such as the left-pad incident has increased awareness of how vulnerable relying on these packages are, there is still some work to be done when it comes to getting developers to take the extra research step to determine if a package is up to standards. Finding metrics of different packages and comparing them is always a difficult and time consuming task, especially since potential vulnerabilities are …

Power Output Modeling And Optimization For A Single Axis Tracking Solar Farm On Skewed Topography Causing Extensive Shading, Logan J. Smith

Master's Theses

Many utility-scale solar farms use horizontal single axis tracking to follow the sun throughout the day and produce more energy. Solar farms on skewed topography produce complex shading patterns that require precise modeling techniques to determine the energy output. To accomplish this, MATLAB was used in conjunction with NREL weather predictions to predict shading shapes and energy outputs. The MATLAB models effectively predicted the sun’s position in the sky, panel tilt angle throughout the day, irradiance, cell temperature, and shading size. The Cal Poly Gold Tree Solar Farm was used to validate these models for various lengths of time. First, …

Failure Analysis Of The Ulnar Collateral Ligament For Youth Baseball Pitchers, Carlos Soto

Master's Theses

The objectives of this study were to (1) use kinetics from motion analysis and inverse dynamics to calculate the stress experienced by the ulnar collateral ligament (UCL) during a typical pitch cycle, (2) compare calculated maximum UCL pitching stresses to failure properties, and (3) investigate correlations between UCL stress with anthropometric and pitching biomechanical parameters. Prior motion analysis experiments of eighteen 10- to 11- year-old baseball pitchers throwing 10 fastballs were analyzed. Maximum internal elbow varus torques were calculated using inverse dynamics methods during a typical pitch cycle. Calculations used axial loading stress equations and maximum internal elbow varus torques …

The Impact Of Myoblast Transplantation On Collateral Capillary Arteriogenesis And Macrophage Phenotype, Christine Hue Do

Biomedical Engineering

Gangrene, pain, loss of limb function, amputation, and death are only few of the grievous consequences associated with peripheral arterial disease (PAD), a vascular disease caused by an obstruction that narrows the blood vessels. Since some patients have collateral vessels that can re-route blood to its downstream destination, much focus has been spotlighted upon discovering the mechanism of this process, termed arteriogenesis, as well as cell therapies to increase arterial diameter of collateral vessels. Since some patients do not have native pre-existing collateral vessels, another method to re-route blood is through arterialized collateral capillaries (ACC), which is the conversion of …

Calibrated Tensioner For Total Knee Arthroplasty Gap Balancer, Lauren Henigman, Jaypreet Dhanota, Corey Catuara

Biomedical Engineering

The purpose of this project was to design a device that interfaces with the previously created gap balancer to simultaneously measure the gap between the femur and tibia and measure the tension in the ligaments of the knee. First, we met with Dr. Delagrammaticas to outline the key customer requirements: we wanted the device to be precise, sterilizable, reliable, and compatible with the gap balancer. Based on the customer requirements, we outlined the specifications that would drive our design and testing, which included precision, ease of use, size, and material properties.

Stair Wagon To Heaven, Maria Cristina Solis Andrade, Nick Ryan Dion, Alexander Pham

Biomedical Engineering

Our design process began with developing a list of questions for our sponsor based on the problem statement we were provided. We took these questions to interview our sponsor. From this interview, we derived a series of customer requirements, which were then used to develop our more specific engineering specifications (Table 8.1). We used these engineering specifications to develop a design morphology. Each of our group mates used the concepts from our design morphology to develop their own full concept sketches. We used Pugh charts to compare the different aspects of each design. The designs were compared based off their …

A Critique Of Scanlon On The Scope Of Morality, Benjamin A. Elmore

Between the Species

In this essay, I argue that contractualism, even when it is actually used to construe our moral duties towards non-human animals, does not do so naturally. We can infer from our experiences with companion animals that we owe moral duties to them because of special relationships we are in with them. We can further abstract that we owe general moral duties to non-human animals because they are the kinds of beings that we can have relationships with, and because of the capacities that make possible this relational capacity. This type of approach better explains our duties to non-human animals and …

Wild Animal Suffering And The Laissez-Faire Intuition, Beka Jalagania

Between the Species

Are we required to assist wild animals suffering due to natural causes? The laissez-faire intuition (LFI) says that we are not. On this view, although we may have special duties to assist wild animals, there are no general requirements to care for them. In this article I critically examine the origins of the LFI and assess its reliability. In particular, I attempt to provide answers to the questions such as how people who have come to endorse this intuition form it and whether it is a genuine moral intuition. I conclude that the LFI is the result of various external …

Review Of Andy Lamey's Duty And The Beast: Should We Eat Meat In The Name Of Animal Rights?, Angus Taylor

Between the Species

In Duty and the Beast, Andy Lamey confronts arguments for what he calls new omnivorism – recent arguments that profess to undermine the moral injunction against eating meat that is so prominent in the animal protection (animal rights) movement. Instead of rejecting animal protection as such, the new critics claim that in the pursuit of this objective the consumption of some meat is permissible or even obligatory.

Arguing For Vegetarianism: (Symbolic) Ingestion And The (Inevitable) Absent Referent — Intersecting Jacques Derrida And Carol J. Adams, Mariana Almeida Pereira

Between the Species

In this paper I draw together the notion of the absent referent as proposed by Carol J. Adams, and the notions of literal and symbolical sacrifice by eating the other — or ingestion — advanced by Jacques Derrida, to characterize how animals are commonly perceived, which ultimately forbids productive arguments for vegetarianism. I discuss animals as being literally and definitionally absent referents, and I argue, informed by Derrida’s philosophy, that it is impossible to aim at turning them into present referents without reinforcing symbolic ingestion by linking symbolic ingestion to epistemic appropriation or conceptualization. With this, I highlight the ethical …

Review Of Lorraine Daston's Against Nature, Kyle Johannsen

Between the Species

Lorraine Daston's Against Nature seeks to explain why, in spite of compelling objections to the contrary, human beings continue to invest nature with moral authority. More specifically, she claims that our propensity to moralize nature is traceable in part to human nature. Though I criticize Daston for not paying adequate attention to John Stuart Mill's narrow sense of 'nature', I also highly recommend her book.
