The U.S. Navy and other amphibious military organizations utilize a derivation of the traditional side stroke called the Combat Side Stroke, or CSS, and tout it as the most efficient technique available. Citing its low aerobic requirements and slow yet powerful movements as superior to the traditionally-best front crawl (freestyle), the CSS is the go-to stroke for any operation in the water. The purpose of this thesis is to apply principles of Industrial Engineering to a real-world situation not typically approached from a perspective of optimization. I will analyze pre-existing data about various swim strokes in order to compare them in terms of efficiency for different variables. These variables include calories burned, speed, and strokes per unit distance, as well as their interactions. Calories will be measured by heart rate monitors, converting BPM to calories burned. Speed will be measured by stopwatch and observer. Strokes per unit distance will be measured by observer. The strokes to be analyzed include the breast stroke, crawl stroke, butterfly, and combat side stroke. The goal is to informally test the U.S. Navy's claim that the combat side stroke is the optimum stroke to conserve energy while covering distance. Because of limitations in the scope of the project, analysis will be done using data collected from literary sources rather than through experimentation. This thesis will include a design of experiment to test the findings here in practical study. The main method of analysis will be linear programming, followed by hypothesis testing, culminating in a design of experiment for future progress on this topic.

The definition of "beauty" can be interpreted in many ways but when defining it literally, it is considered as such: "a combination of qualities that pleases the intellect or moral sense" (Oxford Dictionaries). Beauty simply "pleases" the intellect; it does not say that intellect is a factor of beauty itself. Beauty is nice to look at, a mere pleasure to experience in the "moral sense." It does not have anything to do with one's actions, principles or intelligence, but instead the way one presents himself or herself. If someone is deemed as intellectual, does that mean they are not viewed as beautiful? Is that why beauty is rarely associated with brains and vice versa? Has a history of stereotypes and media interference convinced us that these two concepts cannot coexist? And what if we found out that they did? Could we take that person seriously? I decided to challenge the idea of beauty and brains, and see if beauty is in fact measured by its literal definition and controlled by its assumed stereotype, or if other factors apply when deciphering someone's "beauty." First, I will analyze the perceptions and stereotypes of engineers. By looking at the public opinion of both engineers and women engineers, I can show the common struggles engineers face. Next I will look at perceptions of cheerleaders, in particular, professional cheerleaders. Through analyzing current stereotypes and gender roles associated with these women in the spotlight, I can establish how opinions of these women are formed. I will also look at a survey of a sample of Arizona State University students in which we can confirm or deny the results found through research of previous studies. We will also be able to gather personal opinions about why these stereotypes exist and how to break them down. Finally, we will look at personal accounts of current or retired National Football League (NFL) cheerleaders. These will give first-hand examples of what it is like to be both a cheerleader and a woman in STEM (science, technology, engineering, and mathematics).
