Implementação do protocolo de comunicação DTN aplicado para cidades inteligentes
(Universidade Federal de Santa Maria, 2018-08-31)
In a Smart City context, collecting and distributing relevant information to provide every type of service is far beyond necessary. To achieve this connectivity the network have to be prepared to sustain a heavy traffic ...
Exchange bias em bicamadas de NiFe/FeMn: um estudo em função da espessura da camada antiferromagnética
(Universidade Federal de Santa Maria, 2018-12-04)
The exchange bias (EB) arises, generally, from the interfacial coupling between a ferromagnetic
layer (FM) and an antiferromagnetic layer (AFM). The most well-known manifestations
of this phenomenon, in samples with a ...
Síntese de novos pirróis derivados de aminocumarinas
(Universidade Federal de Santa Maria, 2018-07-19)
In this work, the synthesis of new pyrroles derived from aminocoumarins was
developed. First, the synthesis of pyrroles derived from 4-amino-2H-chromen-2-one
was carried out by the Paal-Knorr and Clauson-Kaas reactions, ...
