Several base elements for the provision of quality of service guarantees have been developed in the recent past. Of these, the Differentiated Services (DiffServ) architecture stands out as the most promising. In spite of this, various issues remain, especially when multidomain DiffServ services are concerned. In this case, some forms of distributed management of Service Level Agreements that allow the specification, exchange, enforcement and monitoring of quality of service data must be in place. Although, again, some isolated solutions exist for each of these problems, considerable effort is necessary to make them work together. The project presented in this paper tried to assess the feasibility of providing differentiated quality of service in satellite IP networks, by developing a dynamic Service Level Agreement management solution for an IP over Digital Video Broadcast Satellite system. The functionality of the implemented system comprises system configuration, dynamic SLA negotiation, QoS monitoring and metering, SLA conformance checking, and QoS reporting to customers.
RESUMO -Neste trabalho, as sementes de açaí (Euterpe Olerácea) in natura e impregnadas com solução aquosa de hidróxido de sódio (NaOH) 2 mol/L foram submetidas ao processo de Pirólise em escala Piloto para produção de Biocarvão, Bioóleo e Gases Condensáveis. Os processos de pirólise foram realizados em um reator de 143 L a 350°C, 400°C, 450°C e 1 atm. Após a obtenção dos produtos foram realizados os cálculos de rendimento para cada fração obtida. Com os resultados foi possível perceber principalmente um aumento de até 5,99, 3,76 e 6,56 % (m/m), no rendimento de biocarvão, bio-óleo e biogás, respectivamente, e uma redução significativa de até 11,67% (m/m) para a produção de água no processo com caroços impregnados em comparação com as pirólises de caroços in natura. Os resultados mostraram a eficiência do processo de impregnação em solução alcalina do caroço de açaí para a realização da Pirólise, no que diz respeito, ao incremento da produção de biocarvão bio-óleo e biogás.
