Solving Interoperability within the Smart Building: a Real Test-Bed

Internet of Things (IoT) is a key pillar in various smart-* domains, including smart home, smart building, intelligent transportation systems, industrial Internet, to name a few. Its potential in terms of value creation is extraordinary, according to economic estimates from many market sectors. At the same time, there are some technical challenges to face, which could refrain IoT adoption. In this study, the attention is focused on interoperability and data quality issues from a pragmatic standpoint. In particular, a real smart building testbed has been set-up by integrating two different IoT platforms: TLSensing and NetwOrked Smart Object (NOS). The former has been developed to enable the quick deployment of a IPv6 over the TSCH mode of IEEE 802.15.4e (6tisch) IoT network and to expose the data gathered from sensors through a web interface. The latter is a middleware that handles heterogeneous data sources and offers a unifying view to users. The resulting IoT system is able to: (i) gather data from multiple sources, including multimedia ones; (ii) expose network resources to user through a common interface; (iii) enforce security and data quality checks. The performance of this system has been experimentally analyzed to demonstrate a satisfactory responsiveness and ability to meet the aforementioned requirements

A Inconfidência Mineira e Tiradentes vistos pela imprensa: a vitalização dos mitos (1930-1960)

Este artigo analisa as apropriações, pela imprensa, das representações da Inconfidência Mineira e especialmente de Tiradentes, entre as décadas de 30 e 60 do século XX, quando foi muito intensa a preocupação com a memória do movimento e de seu mais ilustre personagem. A análise da produção jornalística sobre o herói nacional procura identificar os principais elementos constituidores desses textos indicando, por um lado, a vitalidade dos mitos e, por outro, o poder persuasivo das associações estabelecidas entre o sacrifício heróico de Tiradentes e as condutas dos que se colocam como seus herdeiros, buscando no passado a legitimação para as ações do presente.<br>This article shows how Brazilian press appropriates the representations of the Inconfidência Mineira and specially of Tiradentes between the decades of 1930 and 1960. It intends to identify the main elements of these elaborations, such as the vitality of the national hero myth and the persuasive power of the associations between Tiradentes's sacrifice and his modern heirs. The legitimation of present actions is based on past events
