Redes De Petri Híbridas Diferenciais: Aplicação Na Modelagem E No Gerenciamento Dinâmico De Energia De Redes De Sensores Sem Fio

In this work a formalism named Differential Hybrid Petri Nets to model and simulate hybrid systems is presented. It is based on the main elements of the semantics of the hybrid automaton and the modeling power of Petri nets. Considering that Wireless Sensor Networks are hybrid systems, this formalism is applied to model a Dynamic Power Management technique based on battery Capacity (GDC). There...

Uma Proposta de Perfil de Conjuntos de Dados na Web com Enriquecimento Semântico

The lack of metadata to describe datasets published on the Web makes their location and access by search engines or applications more difficult. Providing a dataset profile facilitates communication between publishers and consumers and also the integrated use of datasets. This paper proposes an approach that describes datasets on the Web by the generation of a semantically enriched descriptive ...

Agregação e Predição de Dados Em Rede com Precisão Ajustável no Processamento de Consultas em Redes de Sensores Sem Fio

Over the past few years, many research works in Wireless Sensor Networks (WSN) have been focusing on node power saving. In order to achieve this goal, the amount of data sent over the node network is usually reduced. In this work, we propose an efficient strategy that aggregates and predicts data in WSN, aiming to reduce the data volume sent over the network and thus maximizing the network life...

Uso de design probes no design de tecnologias para terapeutas de crianças com autismo

Individuals with autism have difficulties in the areas of communication, social interaction and behavior. There is a large variation in the degree of difficulty among these individuals and it is critically important to develop customized therapies and materials for them. In general, the technologies for this audience don’t offer means of customization to meet the needs of each individual. In th...
