Modeling Vehicle Dynamics

Kelvin Than

In order to create successful control systems in vehicles to improve their fuel efficiency and cruise control capabilities, an effective vehicle model must be developed. This paper discusses a vehicle model that uses feedback control in conjunction with a longitudinal energy balance to calculate a velocity profile for input into the adaptive cruise control (ACC) system. Ultimately, with future road information and proper engine control, gasoline consumption can be reduced.

Evaluating Indoor Air Quality

Benjamin Chu

With data centers becoming bigger and bigger, their energy demands are becoming more and more severe. A large component of this is cooling. Economizers work by turning off the power consuming chillers and bringing in large amounts of cool outside air. This cutback of chiller operating hours results in energy savings. But, industry is hesitant to install economizers because indoor contamination can negate any energy savings. This paper explores whether the indoor air quality inside economizer- based data centers is clean enough for large-scale rollout.

Unmanned Aerial Vehicles

Hernan Acevedo, Kevin Krut, Quang Vu

Unmanned Aerial Vehicles (UAVs) are pilot-less aircraft that can potentially revolutionize our traffic in the sky. Currently, UAVs are mainly used in military aircraft, but also have some general applications. Intricate technology in computers, sensors, and guidance systems are on-board the aircraft. Advancement of UAV technology only enhances their importance in everyday life.
