Hydrogen gas is useful when trying to understand galaxies because it helps make
stars. In space, hydrogen gas is in many cases in a form called neutral hydrogen
(HI). This gas emits a faint type of light called the 21 cm line, which is a
type of radio wave. This light is useful because it can go through dust in
space, unlike optical light. This means we can use it to look inside galaxies
and study the gas even if there is dust that is in front of stars in the galaxy.
In my research I was given data from a telescope called the Very Large Array
(VLA), which produces data cubes containing information about the intensity of
emission as a function of position and velocity. The Very Large Array (VLA) uses
advanced interferometry and a large collecting area to gather high-sensitivity
data more quickly, making observations faster and with better resolution, and it
can observe 21cm emission. These clear radio images show where the hydrogen gas
is, how it moves, and how much of it there is in a galaxy. This gives us
information about how stars are forming and how galaxies change.
In this project, I studied a galaxy called Markarian 54 (MRK54). MRK54 is
interesting to study because it is a galaxy merger. When this happens, the gas
gets pulled into elongated structures, like tidal tails, and stars can start
forming in new places. By looking at where the gas is and how it is moving, we
can learn how galaxy collisions change the shape of a galaxy and what happens to
the gas during and after the galaxies have merged. I looked at the 21 cm radio
waves from the hydrogen gas in MRK54 and I created moment maps to show where the
gas is, how it moves, and how turbulent it is. These maps are tools that help us
learn more about the hydrogen makeup in the galaxy.
To make these maps, some challenges I faced in analyzing this data included
cleaning up the data by removing noisy parts and adjusting errors in the
measurements. I also used the galaxy’s redshift (z =0.0449), which is a number
that tells us how far away the galaxy is. This redshift was found in a study by
Leitet and others in 2013. I used the equations for the moment maps from another
study by Walter and others in 2008.
An insight and analysis into the process of directing an engaging and meaningful
production of children’s theatre through Alison Gregory’s Junie B. Jones Is Not
a Crook, adapted from Barbara Park’s vibrant stories. This examination considers
how a thoughtful directorial approach can elevate a play beyond entertainment,
using the unique power of children’s theatre to inspire joy, curiosity, and
learning, not only to entertain, but also to enrich the minds of all who
experience it. Through a careful study of the directorial process, this work
explores how a well executed piece of children’s theatre can create an impactful
experience for audiences of all ages, fostering a shared space of growth,
learning, and fun.
Gymnastics is a popular sport with hundreds of thousands of participants.
Gymnastics also has a high injury rate among participants. Unfortunately,
gymnastics requires specific rehabilitation and not much information exists on
how to properly rehab gymnasts. The goal of this paper was to find existing
literature about treating gymnasts’ injuries and analyze the results. Finally,
recommendations were made in terms of future research.
Dans cette thèse, j'analyserai le film Taafe Fanga (Pouvoir de Pagne en
français), un film de 1997 du Mali, réalisé par Adama Drabo. Le film suit
l'histoire du village de Yanda où des femmes, avec l'aide d'un masque qui
invoque la peur dans des hommes, changent des rôles de genre, leur permettent de
prendre le rôle masculin et dominant et mettent des hommes dans les rôles que
les femmes tenaient avant. J'examinerai ce film d'un angle womaniste. J’affirme
que, bien que les femmes dans le film d'Adama Drabo qui s'appelle Taafe Fanga
luttent pour les droits des femmes, ce n'est pas une perspective féministe, mais
womaniste. Je soutiens que ce film est womaniste, un terme a créé par des
Africaines, plutôt que féministe, parce que le womanisme est conçu pour des
expériences africaines comme qui créé par des Africaines, pendant que le
féminisme a traditionnellement a organisé soi-même autour des expériences et des
épreuves des femmes occidentales, plus spécifiquement des femmes blanches.
Le womanisme a émergé quand des Africaines trouvaient que le féminisme de
l'ouest n'alignait pas leurs expériences. Alors, des Africaines ont formulé un
terme nouveau à décrire leur lutte pour les droits des femmes, dans leurs
propres buts. Les womanismes de Clenora Hudson-Weems et Chikwenye Ogunyemi sont
plus détaillés et érudites et alignent le plus avec des expériences africaines,
plutôt que les womanismes des femmes comme Alice Walker qui focalise plus sur
les expériences des femmes afro-américaines. Cette distinction est importante
parce que le film que j’étudierai a lieu en Afrique, non aux États-Unis. Pendant
l’analyse de ce film, la théorie et la recherche womaniste et non la recherche
cinématographique, mènent ma méthodologie à cause du nombre limité de la
recherche sur des films africains.
L’analyse qui existe n’emploie pas souvent de nom ou de terme pour comment les
films représentent les femmes et les droits des femmes. J’ajouterai une analyse
womaniste à ces deux films.
When you look at baseball at every level today, it’s clear that the sport has
become predominantly a "white man's" game. The lack of African American
representation at both the player and fan levels has become a significant issue,
and many wonder how the sport can reclaim its connection with African American
communities and revitalize its cultural relevance in the years to come.
Not only has such a shortage prevailed within the MLB, but also at a collegiate
level. According to the NCAA’s 2014-15 student-athlete ethnicity report, only
four percent of baseball players at the Division I, II, and III levels combined
were African American (NCAA, 2015). This disparity continues down through high
school, youth, and recreational baseball, specifically within inner-city areas.
The decline of baseball in inner-city areas has led to diminished participation,
reduced diversity in the sport, and altered the trajectory of baseball’s
popularity and development over time. The purpose of this paper is to examine
the roots of the racial disparity within the game, specifically focusing on
inner-city youth, and to investigate the factors contributing to this issue.
Baseball, often referred to as America’s pastime and once one of the most
popular sports in the country, now faces an alarming decline in African American
participation. This research will explore the reasons behind this decline and
discuss ongoing efforts to address the problem.
This paper describes relighting neural radiance fields for novel view synthesis.
View synthesis is the problem of using input images with corresponding camera
angles to produce a photorealistic 3D model of an environment and its objects.
Neural radiance fields (NeRFs) were created as a solution to view synthesis.
Neural radiance field models work well for generating realistic 3D models from
2D image inputs; how-ever, they do not support changing the lighting or placing
the objects from the input images into different environments. The problem comes
from the fact that NeRFs rely on a neural network that is essentially overfitted
to the original environment used in the training. This means an object in a
given scene cannot be placed into a different scene using the NeRF neural
network model. A new model, relightable neural radiance fields (ReNeRFs), has
been proposed to combat this issue. ReNeRFs have the ability to control the
lighting of an object and place it into novel environments using an image-based
relighting approach.
The increasing use of AI for code generation presents significant security
challenges, as these tools often lack inherent security awareness and can
produce vulnerable code. This paper investigates these security risks, outlining
common types of vulnerabilities (such as injection flaws and improper resource
handling) found in AI-generated code. It further explores and evaluates
mitigation techniques aimed at im-proving code security, including model
fine-tuning and adversarial strategies like Security Verifier Enhanced Neural
Steering (SVEN). Findings indicate that while current methods offer promising
ways to reduce vulnerabilities, ongoing research and development are crucial for
the secure and responsible deployment of AI in software development.

Franklin Delano Roosevelt (FDR) was the 32nd president of the United States of
America. He served an unprecedented four terms in office and delivered four
inaugural speeches. He set himself up for success in his first inaugural
address, claiming, “there is nothing to fear but fear itself.” This famous
passage, among others in FDR’s first inaugural address, worked as rhetorical
maneuvers meant to both introduce FDR to the presidency as well as leave a
lasting impression on the citizens of the United States facing hardship due to
the Great Depression. Through the application of Lloyd Bitzer’s “rhetorical
situation,” Edward Corbett and Robert Connors’ definitions of stylistic devices
and Karlyn Campbell, Kathleen Jamieson and Elizabeth Dudash’s genre
requirements, this paper works to rhetorically examine FDR’s first inaugural
address.
Monte Carlo tree search (MCTS) is a probabilistic algorithm that uses
lightweight random simulations to selectively grow a game tree. MCTS has
experienced a lot of success in domains with vast search spaces which
historically have challenged deterministic algorithms [3]. This paper discusses
the steps of the MCTS algorithm, its application to the board.
As costs of landfilling and incinerating waste rise, many campuses are beginning
to consider alternatives for dealing with food waste generation. In August of
2012, the University of Minnesota, Morris began composting its food waste and
food-soiled paper using the turned windrow method. While hailed as a sustainable
alternative, with benefits including reduced need for chemical fertilizers,
water, and pesticides, higher crop yields, revitalization of poor soils,
avoidance of methane and leachate generation in landfills, pollution prevention,
and extension of landfill life, many costs are also incurred with the composting
alternative ranging from the need to purchase organics collection bins to the
time needed each day to manage the actual composting site. The question,
therefore, is whether it is worth continuing an on-site composting program at
Morris. The cost-benefit analysis includes the steps outlined in Boardman,
Greenberg, Vining, and Weimer’s textbook Cost Benefit Analysis Concepts and
Practice: specify the set of alternative projects, determine standing, identify
the impact categories, estimate the impacts, monetize all impacts, calculate net
present values, perform sensitivity analysis, and make a recommendation. Despite
significant costs, I found that the data clearly stands to support the project’s
continuance. While the project is still in its fledgling state, this analysis
can be used as a justification to continue the composting project and serve as a
model for other campuses to follow.
Within society it appears that dissatisfaction with one’s body is seen as a
female-exclusive problem. However, limited research on men and body
dissatisfaction suggests that men do experience body dissatisfaction, and these
rates are increasing over time. The present literature review seeks to tie
together consistent themes seen within these studies, and proposes a model based
on these connections that may explain the growth in prevalence rates over time.
Two theories, threatened masculinity theory and self-discrepancy theory, are
also applied within the model. The model presented within this review can help
give new direction to future research on men and body dissatisfaction. By
improving research, we can help eliminate the stereotype that body
dissatisfaction is a “female-exclusive” issue and men who experience clinical
levels of body dissatisfaction can receive the treatment they require.
Spammers always find new ways to get spammy content to the public. Very commonly
this is accomplished by using email, social media, or advertisements. According
to a 2011 report by the Messaging Anti-Abuse Working Group roughly 90% of all
emails in the United States are spam. This is why we will be taking a more
detailed look at email spam. Spam filters have been getting better at detecting
spam and removing it, but no method is able to block 100% of it. Because of
this, many different methods of text classification have been developed,
including a group of classifiers that use a Bayesian approach. The Bayesian
approach to spam filtering was one of the earliest methods used to filter spam,
and it remains relevant to this day. In this paper we will analyze 2 specific
optimizations of Naive Bayes text classification and spam filtering, looking at
the differences between them and how they have been used in practice. This paper
will show that Bayesian filtering can be simply implemented for a reasonably
accurate text classifier and that it can be modified to make a significant
impact on the accuracy of the filter. A variety of applications will be explored
as well.
