Estimation of electrical machine speed using sensorless technology and neural networks
(2008-12-01)
The use of sensorless technologies is an increasing tendency on industrial drivers for electrical machines. The estimation of electrical and mechanical parameters involved with the electrical machine control is used very ...
Topological design of Wireless sensor network: Formulations and exact algorithms
(Universidade Federal de Minas GeraisUFMG, 2018-08-31)
The subject of this thesis is the design of Wireless Sensor Networks (WSN). Given a limited set of sensors and a single sinks, we are particularly interested in the topological WSN design problem. This problem consists in ...
A survey on key management mechanisms for distributed Wireless Sensor Networks
(ELSEVIER SCIENCE BV, 2010)
Wireless Sensor Networks (WSNs) have a vast field of applications, including deployment in hostile environments. Thus, the adoption of security mechanisms is fundamental. However, the extremely constrained nature of sensors ...
Sensor nodes fault detection for agricultural wireless sensor networks based on NMF
(Elsevier B.V., 2018)
Nowadays, Wireless Sensor Networks (WSN) are widely been employed to solve agricultural problems related to the optimization of scarce farming resources, decision making support, and land monitoring. However, the small ...
Computational simulation of wireless sensor networks for pesticide drift control
(SpringerNetherlands, 2014-06)
The efficient application of low cost pesticides is a challenge for agricultural production. Pesticide drift is a major cause of environmental contamination. At the time of application, it is essential to know the environmental ...
