5. Methods for truck dispatching in open-pit mining.
Material transportation is one of the most important aspects of open-pit mine operations. The problem usually involves a truck dispatching system in which decisions on truck assignments and destinations are taken in real-time. Due to its significance, several decision systems for this problem have been developed in the last few years, improving productivity

9. Model checking underwater vehicles control architectures: a formal specification based approach. / Checagem de arquiteturas de controle de veículos submarinos: uma abordagem baseada em especificações formais.
The development of control architectures for Underwater Vehicles is a complex task. These control architectures might be chracterised by the following attributes: real-time, multitasking, concurrency, and distributed over communication networks. In this scenario, we have multiple processes running in parallel, possibly distributed, and engaging in communicat

12. AnÃlise de sistemas operacionais de tempo real
Critical Real-Time Systems are becoming more used each day. The great complexity in creating real-time applications favors the sprouting of new resources that facilitate the designer to adapt such systems to his/her needs. Among them there are the Real-Time Operating Systems (RTOS). A consequence of this is that RTOS adoption have significantly increased, ma
