Alocação de canais para roteamento geográfico em redes de sensores e atuadores sem fio empregando a teoria dos jogos
(Universidade Federal de Santa Maria, 2012-05-25)
Wireless sensor and actuator networks are expected to grow quickly in size due to the
decreasing cost of nodes. For such large scale networks, the geographic routing algorithm
is a suitable approach. It finds a route for ...
Análise do ciclo de vida da tecnologia dos veículos com motores de combustão interna e dos veículos eletrificados
(Universidade Federal de Santa Maria, 2023-03-31)
In the current scenario, about 99.8% of transports are powered by internal
combustion engines (ICE). Transport is still responsible for 24% of direct CO2
emissions through the burning of fuels. Presently, efforts have ...
Recuperação de compostos bioativos de resíduos oriundos do processamento de óleos vegetais por meio da aplicação do processo combinado de esterificação-destilação molecular
(Universidade Federal de Santa Maria, 2023-04-14)
The vegetable oil refining process generates residues that can be reused to recover
compounds with high-added value. The deodorized distillates are a source for the
recovery of vitamin E, phytosterols, and squalene. Among ...
