Evolving robots to play dodgeball
In nearly all videogames, creating smart and complex artificial agents helps ensure an enjoyable and challenging player experience. Using a dodgeball-inspired simulation, we attempt to train a population of robots to develop effective individual strategies against hard-coded opponents. Every evolving robot is controlled by a feedforward artificial neural network, and has a fitness function based on its hits and deaths. We evolved the robots using both standard and real-time NEAT against several teams. We hypothesized that interesting strategies would develop using both evolutionary algorithms, and fitness would increase in each trial. Initial experiments using rtNEAT did not increase fitness substantially, and after several thousand time steps the robots still exhibited mostly random movement. One exception was a defensive strategy against randomly moving enemies where individuals would specifically avoid the area near the center line. Subsequent experiments using the NEAT algorithm were more successful both visually and quantitatively: average fitness improved, and complex tactics appeared to develop in some trials, such as hiding behind the obstacle. Further research could improve our rtNEAT algorithm to match the relative effectiveness of NEAT, or use competitive coevolution to remove the need for hard-coded opponents.

Limiting Sample Damage In Laser Diagnostics
Tests conducted comparing the effect exposure of Paracetamol to a laser with oven heating a sample to a temperature above its melting point, 169 degrees Celsius showed similarities. This implies that the primary cause of sample damage during Raman spectroscopy is heating. It was found that inserting a piece of glass between the sample and the microscope lens dramatically reduced the ability of the laser to damage samples. Computer models indicate that rotating a sample at 8 rotations per minute could be an effective method of limiting sample damage, and is a potential alternative to active cooling if this becomes financially and logistically viable in industry. Active sample cooling was investigated, but results proved inconclusive. This is a key area for any future research on the topic.
Challenging Environmental Colonialism
In this journal, I will discuss modern day environmental exploitation as it relates to native americans. In my research, I found no shortage of opposition to the dangers of natural resource extraction on tribal lands. While tribes remain sovereign nations, the overarching authority and loopholes of federal and state governments force many indigenous people to remain vulnerable to the violences of capitalism. Against all odds, native individuals and organizations throughout the country, and globe, meet these offenses with fervent opposition. Here, I will explore the tactics and victories of Indigenous North Americans.

CoppeTeX - A LaTeX toolkit for writing thesis and dissertations
The aim of the CoppeTeX project is to provide a LaTeX framework suitable for writing thesis and dissertations according to the formatting rules established by the Alberto Luiz Coimbra Institute for Graduate Studies and Research in Engineering (COPPE/UFRJ). It is also intended to construct a friendly environment where users can discuss general LaTeX issues, and to which all COPPE students (but not exclusively) are pleasantly invited.
The CoppeTeX toolkit comprises a LaTeX document class, and BibTeX and Makeindex styles. Its document class allows the composition of MSc dissertations, DSc qualifying exams, and DSc thesis. The BibTeX style creates numbered lists of bibliographic references whose entries are sorted in the order they are cited. The Makeindex style helps to create sorted lists of abbreviations and symbols. There is still a mailing list where people can post questions concerning the distributed material, as well as TeX/LaTeX related problems.

Automatic Glossaries in LaTeX
This example shows how to generate automatic glossaries with the glossaries package. For more information, there's a good guide in the LaTeX wikibook, and also in the package documentation.
