Description
An in-depth analysis on the effects vortex generators cause to the boundary layer separation that occurs when an internal flow passes through a diffuser is presented. By understanding the effects vortex generators demonstrate on the boundary layer, they can be utilized to improve the performance and efficiencies of diffusers and other internal flow applications. An experiment was constructed to acquire physical data that could assess the change in performance of the diffusers once vortex generators were applied. The experiment consisted of pushing air through rectangular diffusers with half angles of 10, 20, and 30 degrees. A velocity distribution model was created for each diffuser without the application of vortex generators before modeling the velocity distribution with the application of vortex generators. This allowed the two results to be directly compared to one another and the improvements to be quantified. This was completed by using the velocity distribution model to find the partial mass flow rate through the outer portion of the diffuser's cross-sectional area. The analysis concluded that the vortex generators noticeably increased the performance of the diffusers. This was best seen in the performance of the 30-degree diffuser. Initially the diffuser experienced airflow velocities near zero towards the edges. This led to 0.18% of the mass flow rate occurring in the outer one-fourth portion of the cross-sectional area. With the application of vortex generators, this percentage increased to 5.7%. The 20-degree diffuser improved from 2.5% to 7.9% of the total mass flow rate in the outer portion and the 10-degree diffuser improved from 11.9% to 19.2%. These results demonstrate an increase in performance by the addition of vortex generators while allowing the possibility for further investigation on improvement through the design and configuration of these vortex generators.

Description
This experiment used hotwire anemometry to examine the von Kármán vortex street and how different surface conditions affect the wake profile of circular airfoils, or bluff bodies. Specifically, this experiment investigated how the various surface conditions affected the shedding frequency and Strouhal Number of the vortex street as Reynolds Number is increased. The cylinders tested varied diameter, surface finish, and wire wrapping. Larger diameters corresponded with lower shedding frequencies, rougher surfaces decreased Strouhal Number, and the addition of thick wires to the surface of the cylinder completely disrupted the vortex shedding to the point where there was almost no dominant shedding frequency. For the smallest diameter cylinder tested, secondary dominant frequencies were observed, suggesting harmonics.

Description
The purpose of this paper is to discover what geometric characteristics of a wing and airfoil help to maximize leading edge suction through experimental testing. Three different stages of testing were conducted: a Proof of Concept, a Primary Experiment, and a Secondary Experiment. The Proof of Concept shows the effects of leading edge suction and the benefits it can posses. The Primary Experiment provided inconclusive data due to inaccuracies in the equipment. As a result, the Secondary Experiment was conducted in order to reduce the error effect as much as possible on the data. Unfortunately the Secondary Experiment provided inaccurate data as well. However, this paper does provide enough evidence to begin to question some of the long held beliefs regarding theoretical induced drag and whether it is true under all circumstances, or if it is only a good approximation for airfoils with full leading-edge suction effects.

Description
This interdisciplinary thesis examines the possible relationship between the public speaking experience for women and the gender gap in political ambition. First, a historical analysis of women public speakers ranging from the 1800s to the Suffragettes to female politicians in the 1900s reveals a pattern of female public speakers in politics receiving extreme criticism for their communicative behavior. The thesis then turns to the socialization of young girls, highlighting how gameplay in children translates into gendered communicative behavior in adult women. Next, an examination of the pedagogy of public speaking showcases how the public speaking experience is different for women than it is for men, and how public speaking traditionally is taught in a masculine style. Then, through a review of the literature on the gender gap in political ambition, it is seen that not only are women severely underrepresented in political office in the United States, but women have far less political ambition than men. And a case study of the 2008 presidential primaries and elections, highlighting modern women in politics, demonstrates that the few women who are politically ambitious in the 21st century face criticism that mirrors those faced by political women decades and centuries prior. Finally, the thesis offers possible solutions to changing the experience of women as public speakers and fostering political ambition in women.

"The Hunger Games: What a Dystopic World Reveals about Modern Society" is an interdisciplinary thesis that examines the impossibility of revolutionary stories or concepts in popular culture by specifically analyzing the Hunger Games project. First, an analysis of what young adult fiction is and how it is written is provided. The formulaic way in which modern adolescent literature is written provides the basic structure for Suzanne Collins' Hunger Games trilogy. The second chapter examines the main character of the Hunger Games series, Katniss Everdeen. The way in which this young female heroine relinquishes her independence and courage due to being consistently undermined by the men and political leaders in her life is traced by following the development of the story throughout the three novels. The third chapter of the thesis delves into how the entire Hunger Games project of novels and films fits into current popular culture. An analysis of the mass production of the novels, and then turning the books into films, merchandise, and further commercialization of the story is discussed in detail throughout the chapter. Finally, the thesis discusses the responsibility authors of young adult literature should assume when addressing a young impressionable audience and how Collins took advantage of the position she had in telling the story of Katniss Everdeen.

Description
A model has been developed to modify Euler-Bernoulli beam theory for wooden beams, using visible properties of wood knot-defects. Treating knots in a beam as a system of two ellipses that change the local bending stiffness has been shown to improve the fit of a theoretical beam displacement function to edge-line deflection data extracted from digital imagery of experimentally loaded beams. In addition, an Ellipse Logistic Model (ELM) has been proposed, using L1-regularized logistic regression, to predict the impact of a knot on the displacement of a beam. By classifying a knot as severely positive or negative, vs. mildly positive or negative, ELM can classify knots that lead to large changes to beam deflection, while not over-emphasizing knots that may not be a problem. Using ELM with a regression-fit Young's Modulus on three-point bending of Douglass Fir, it is possible estimate the effects a knot will have on the shape of the resulting displacement curve.

Description
The lack of diversity for minorities and especially women of color is astounding in the film industry. Film is supposed to imitate life, but that can't happen successfully unless more stories are told about different kinds of people. The following thesis focuses on the diversity struggle, specifically for black women by analyzing Hollywood films and critiquing the structure of the film industry. I chose to focus on films made in Hollywood because they are extremely ubiquitous, meaning they can reach many different people from around the world. Hollywood films set the tone and build impressions in other countries about what certain types of people look and act like and the stereotypes associated with these films reach millions of minorities as well. Essentially, solving the diversity problem will make a larger impact not only in America, but around the world. The four chapters of this thesis focus on the history of blacks in film, representation of black women, black women behind the screen, and improvement for the future of the industry.

Description
This thesis seeks to compile the best practices described in popular advice literature for women in leadership. The analyzed books are roughly categorized into two types, which will be labeled the Take No Prisoners and Girl Power approaches. The thesis then further transitions into discussions on three separate issues that women face during their careers. The first issue addresses the initial mindset that women must overcome in order to begin a path to success: "Striving for Perfection." Continuing from that is the issue of "Working with Others," which refers to the need to network and engage in mentoring. It represents the many stepping stones that all business leaders must use, but that womyn need to navigate differently than men. Next, the thesis will discuss the topic of "Assertiveness." While this advice is helpful, it becomes apparent that not all of it is applicable to women in the Millennial generation. To address this, the thesis will conclude with an analysis of the texts' relevancy to Millennial women, as they begin their careers and/or begin to enter leadership roles within their careers. This section will also include a prediction on how such professional advice texts will differ once Millennial women progress in their careers and pass down their own knowledge and experiences.

A home holds so much more meaning and power than the physical structure of a house. As much as our personal space serves as an extension of ourselves, it also affects us. Furthermore, whichever state a home environment is in has a major impact on psychological well-being. This thesis is an investigation of the idea of home design as a means of addressing psychological anxiety through the point of view of a college student. The information is divided into three chapters; which are Overview of Relevant Scholarly Literature, Design Philosophies, and Personal Experience. Within the scholarly literature, well-being and anxiety are two trends in the studies of environmental psychology, positive psychology, and the humanities. There is still limited knowledge in these areas, so it is important to expand the understanding of the home environment's influence. Based on this research, well-known philosophies, and personal experience, design philosophies are an effective way to potentially improve well-being and reduce anxiety, especially for college students. While Hygge and Wabi-sabi are both design philosophies rising in recognition, Feng Shui is already widespread around the world. Some of the recommendations discoverer were to add cozy décor and lower lighting options to soften the room, get rid of extra clutter taking up space, or bring in nature with greenery and fresh flowers. However, these objects have countless interpretations and there is not a single correct answer. In the end, adjusting the space to be individualized will bring more comfort and these efforts will begin to make a difference in the user’s state of mind.

Description
The thesis is an investigation on current regulations of commercial aircraft landing and take-off procedures and an analysis of potential weaknesses within the regulatory system for commercial aerospace. To determine such flaws, an area of worse-case scenarios with regard to the aforementioned flight operations was researched. The events selected to best-depict these scenarios where incidents of aircraft overrunning the runway, referred to as runway excursions. A case-study conducted of 44 federal investigations of runway excursions produced data indicating four influential factors within these incidents: weather, pilot error, instrument malfunction, and runway condition. Upon examination, all but pilot error appeared to have federal enforcement to diminish the occurrence of future incidents. This is a direct result of the broad possibilities that make up this factor. The study then searched for a consistent fault within the incidents with the results indicating an indirect relationship of thrust reversers, a technique utilized by pilots to provide additional braking, to these excursions. In cases of thrust reverser failure, pilots' over-reliance on the system lead to time being lost from the confusion produced by the malfunction, ultimately resulting in several different runway excursions. The legal implication with the situation is that current regulations are ambiguous on the subject of thrust reversers and thus do not properly model the usage of the technique. Thus, to observe the scope of danger this ambiguity presents to the industry, the relationship of the technique to commercial aerospace needed to be determined. Interviews were set-up with former commercial pilots to gather data related to the flight crew perspective. This data indicated that thrust reversers were actively utilized by pilots within the industry for landing operations. The problem with the current regulations was revealed that the lack of details on thrust reverser reflected a failure of regulations to model current industry flight operations. To improve safety within the industry, new data related to thrust reverser deployment must be developed and enforced to determine appropriate windows to utilize the technique, thus decreasing time lost in confusion that results from thrust reversers malfunction. Future work would be based on producing simulations to determine said data as well as proposing the policy suggestions produced by this thesis.
