In a 2004 paper, John Nagy raised the possibility of the existence of a hypertumor \emph{i.e.}, a focus of aggressively reproducing parenchyma cells that invade part or all of a tumor. His model used a system of nonlinear ordinary differential equations to find a suitable set of conditions for which these hypertumors exist. Here that model is expanded by transforming it into a system of nonlinear partial differential equations with diffusion, advection, and a free boundary condition to represent a radially symmetric tumor growth. Two strains of parenchymal cells are incorporated; one forming almost the entirety of the tumor while the much more aggressive strain

appears in a smaller region inside of the tumor. Simulations show that if the aggressive strain focuses its efforts on proliferating and does not contribute to angiogenesis signaling when in a hypoxic state, a hypertumor will form. More importantly, this resultant aggressive tumor is paradoxically prone to extinction and hypothesize is the cause of necrosis in many vascularized tumors.

In competitive Taekwondo, Electronic Body Protectors (EBPs) are used to register hits made by players during sparring. EBPs are comprised of three main components: chest guard, foot sock, and headgear. This equipment interacts with each other through the use of magnets, electric sensors, transmitters, and a receiver. The receiver is connected to a computer programmed with software to process signals from the transmitter and determine whether or not a competitor scored a point. The current design of EBPs, however, have numerous shortcomings, including sensing false positives, failing to register hits, costing too much, and relying on human judgment. This thesis will thoroughly delineate the operation of the current EBPs used and discuss research performed in order to eliminate these weaknesses.

The college experience is enlightening, empowering, educational, but can also be overwhelming and stressful. If one investigates the atmosphere at your standard university campus, there is no doubt that all students are exhausted in their own unique way. The various responsibilities and obligations inherent in the academic course load, student organizations, sports teams, and other extracurricular activities that a student commits to fosters this stress. A common pattern, especially among students, is the progression from stress to exhaustion to lack of motivation, or helplessness. The Mayo Clinic published an article stating: “when stress begins to accumulate from negative or challenging events in life that just keep coming, you can find yourself in a state of feeling emotionally worn out and drained” (https://www.facebook.com/MayoClinicHealthSystem, 2020). That being said, the implementation of gamification in the college experience can significantly improve intrinsic motivation within students, thus reducing the stress and exhaustion. Gamification with regards to higher education is the use of game design elements in non-game contexts in order to engage and motivate learners. The primary purpose of gamification is to make learning more fun and interesting, as well as to increase learners’ engagement, motivation, and productivity. Video games and the concept of gamification in general have shown positive signs of relieved anxiety and increased enjoyment in many different aspects of life, such as education. The overarching goal of introducing gamification into the college environment is simple: To increase satisfaction, learning, participation, engagement, and retention among the student population.
