Determining the Speed of Light
When measuring a speed, the most common way to calculate it is by recording
how far something went and the time it took to go that far. In the case of light,
this is very difficult. One could conceivably shine a light over a vast distance
and have someone else record when they see the light, but this would be difficult
even at large distances. The person recording when they see it will need to have
terrific reflexes to accurately measure a correct time as the time will be very
short. A better method involves the use of a quickly rotating mirror and a beam
of light. By aiming a beam of light o the rotating mirror, then reflecting it
o a second stationary mirror back into the rotating mirror, calculations can be
made on the speed of light. After first hitting the rotating mirror, the mirror
will rotate very slightly in the time it takes the beam of light to return and
will reflect back to a different position from where it came from. By measuring
the displacement of the round trip, a measurement of the speed of light can be
Projeto de Controlador PID por múltiplos pontos da resposta em frequência
O objetivo deste trabalho, desenvolvido para a disciplina de Sistemas de Controle II da UFRGS, é a identificação de pontos da resposta em frequência de uma planta de nível d'água localizada no LASCAR, por meio do uso dos conceitos de função descritiva e ciclo limite. Ademais, será projetado um controlador PID e analisada a dinâmica do sistema em questão, usando-se as informações referidas.

A Statistical Analysis of the Simpson College Football Offense
This project explores the predictability of play-calling of the Simpson College football offense during the years of 2012-2014. The models used to assess the predictability include simple analysis as well as linear and logistic regression.
