Description
This thesis deals primarily with contemporary Brazilian civil-military relations. For most of the 20th century Brazil’s political system was stuck in a cycle of repeated military intervention. At present, Brazil operates as an electoral democracy and has kept the military out of politics since 1985. In order to understand the likelihood of another coup d’état, this thesis considers threats to the military’s corporate interests and deflations of the government’s political legitimacy within Brazil. Given the lack of significant threats to the military’s self-interest and the absence of serious legitimacy deflations, the Brazilian government appears unlikely to have a coup d’état in the near future. It is, however, important to remember that the 2014 World Cup and 2016 Summer Olympics could challenge Brazil’s current political stability and alter the likelihood of military intervention.

For my honors creative project, I decided to create and teach an elementary school Latin curriculum. As a Classics major, I love the Latin language and I was thrilled to be able to introduce my students to the Latin language in an interesting and fun way. I have taught weekly Latin lessons for this school year on Friday afternoons at a local private school. Each class is forty-five minutes long and involves students from kindergarten through eighth grade. The Latin classes were an optional offering after school. The creative element of this honors creative project was recording and compiling my weekly lesson plans. Since these lesson plans were taught in an after school setting, I wanted to ensure that my students found the lessons enjoyable. Therefore, each lesson has a project for the students to work on which enforces the concepts learned in each lesson. I tried to teach the students a variety of vocabulary that would be found in any introductory Latin course. In addition to teaching Latin nouns and verbs, I also tried to teach the class Latin roots that are found in English. I supplemented these lesson plans with stories of Roman mythology or Roman history, so that my students would have a greater appreciation for the Latin language. Almost all of these stories had to be simplified to ensure that they would be age-appropriate to tell to my class. Although my students all had taken Spanish classes, none of them had experience with Latin instruction. It was therefore unsurprising that most of the class showed huge improvement in their pre and post tests, given at the beginning of the school year in August, and again in March. I supplemented these lesson plans in my honors project with a literature review on the history and benefits of Latin instruction. Additionally, I included an extensive annotated bibliography of scholarly and didactic works useful to Latin instructors.

Within the vast array of classical literature, many authors still have not been thoroughly examined. Among these, Palladas of Alexandria, a prominent epigrammatist in the Palatine Anthology, seems to import Epicurean themes. Based on the content and motifs of his poetry, I argue that Palladas leaned on Epicurean philosophy as presented in Lucretius's De Rerum Natura to salvage pagan identity in the midst of Christianity's increased popularity.

The origin of the Latin alphabet has a long history. I am studying the different scripts that contributed to the Latin alphabet and linking how they came into contact through trade routes and wars. Staring as early as the 19th century BC, there are many scripts with their own origins and personalities that are being taken into consideration and picked apart to determine the exact origin of the Latin script.

Description
Unmanned aerial vehicles have received increased attention in the last decade due to their versatility, as well as the availability of inexpensive sensors (e.g. GPS, IMU) for their navigation and control. Multirotor vehicles, specifically quadrotors, have formed a fast growing field in robotics, with the range of applications spanning from surveil- lance and reconnaissance to agriculture and large area mapping. Although in most applications single quadrotors are used, there is an increasing interest in architectures controlling multiple quadrotors executing a collaborative task. This thesis introduces a new concept of control involving more than one quadrotors, according to which two quadrotors can be physically coupled in mid-flight. This concept equips the quadro- tors with new capabilities, e.g. increased payload or pursuit and capturing of other quadrotors. A comprehensive simulation of the approach is built to simulate coupled quadrotors. The dynamics and modeling of the coupled system is presented together with a discussion regarding the coupling mechanism, impact modeling and additional considerations that have been investigated. Simulation results are presented for cases of static coupling as well as enemy quadrotor pursuit and capture, together with an analysis of control methodology and gain tuning. Practical implementations are introduced as results show the feasibility of this design.

Description
I investigate how complementizers, which connect subordinate clauses to the main sentence, develop from other parts of speech, namely prepositions and adverbs. This occurs by the process of grammaticalization, in which a word loses lexicality and gains grammatical function instead. I use computer-based corpus analysis to determine how often certain words are used as each part of speech in my selected texts, and whether they are accompanied by other grammatical words. I use two Old English glosses of the Latin gospels, the Rushworth and Lindisfarne glosses, in order to analyze possible diachronic and geographical differences between the texts. I demonstrate that prepositions develop into adverbs and thence into complementizers with the assistance of certain grammatical accessory words which are later lost. This occurs by the process of reanalysis, in which the language user interprets a word or phrase differently than before.

Description
The Roman satirist Persius composed six satires and one prologue, each displaying his unique style and voice. Persius' voice is often difficult to analyze given his complex language and deliberate obscurity, but a detailed reading of his satires allows the reader glean his message. The Prologue and First Satire illustrate Persius' literary mission and values: to separate himself from his peers by innovating the satires of Lucilius and Horace in order to promote his literary values of Roman-ness, self-sufficiency, and resentful restraint.

Description
De Plantis Aegypti is a medical botany text from 1592, written by Prospero Alpini in Latin. In this text, Alpini details a variety of plants native and grown in Egypt, how they are grown, how they are processed, what they look like, and what if any edible and medical uses are documented. This project focused on transcribing and editing the Latin text, translating the Latin text into English, and comparing the medical claims to the modern scientific literature. This is the first translation of this text into English or any other language. Alpini also wrote two other books, which also have never been translated. The intended goal was to demonstrate that renaissance scholars understood medicine well, if not the mechanisms through which those medicines worked. After analyzing the modern scientific literature on the plants mentioned within the text, it was found that every medical use referenced in the text was either directly supported, indirectly supported, or there was no data from the literature. In other words, none of the medical uses were found to be disproved. On the other hand, quite a few of the plants actually had similar efficacies as modern pharmaceuticals. In addition to the notes on the modern science, there are also quite a few notes based on the grammar and the orthography of the text. This project is but a sampling of the plants mentioned De Plantis Aegypti, there are dozens more, which I plan on translating and doing a similar analysis on at a later date.

Description
There has been a vast increase in applications of Unmanned Aerial Vehicles (UAVs) in civilian domains. To operate in the civilian airspace, a UAV must be able to sense and avoid both static and moving obstacles for flight safety. While indoor and low-altitude environments are mainly occupied by static obstacles, risks in space of higher altitude primarily come from moving obstacles such as other aircraft or flying vehicles in the airspace. Therefore, the ability to avoid moving obstacles becomes a necessity
for Unmanned Aerial Vehicles.
Towards enabling a UAV to autonomously sense and avoid moving obstacles, this thesis makes the following contributions. Initially, an image-based reactive motion planner is developed for a quadrotor to avoid a fast approaching obstacle. Furthermore, A Dubin’s curve based geometry method is developed as a global path planner for a fixed-wing UAV to avoid collisions with aircraft. The image-based method is unable to produce an optimal path and the geometry method uses a simplified UAV model. To compensate
these two disadvantages, a series of algorithms built upon the Closed-Loop Rapid Exploratory Random Tree are developed as global path planners to generate collision avoidance paths in real time. The algorithms are validated in Software-In-the-Loop (SITL) and Hardware-In-the-Loop (HIL) simulations using a fixed-wing UAV model and in real flight experiments using quadrotors. It is observed that the algorithm enables a UAV to avoid moving obstacles approaching to it with different directions and speeds.
