Artificial neural networks applied to DGA for fault diagnosis in oil-filled power transformers

Dissolved Gas Analysis (DGA) is a popular method to detect and diagnose different types of faults occurring in power transformers. This objective is obtained by employing different interpretations of dissolved gases in the mineral oil insulation of such transformers. This paper engages these interpretations and applies appropriate Artificial Neural Networks (ANN) to classify the different faults. Each interpretation...

Radio access network (RAN) architecture development for a 4G Mobile system with reduced interference

The fourth-generation wireless network communications technology standard is called 4G. Users of 4G devices will have the ability to access applications ranging from basic voice communication to seamless real-time video streaming. This paper proposes new techniques for the 4G mobile system, which include base station and cell distribution, channel allocation, and carrier frequencies. In addition, the connection between...
