This paper presents the theory and key experimental findings for an investigation into the generation of bimodal resonance
(frequency splitting) phenomena in mutually over-coupled inductive sensors, and its exploitation to evaluate relative separation and
angular displacement between coils. This innovative measurement technique explores the bimodal resonant phenomena observed
between two coil designs - solenoid and planar coil geometries. The proposed sensors are evaluated against first-order analytical

The synthetic dataset was developed in the Power Electronics and Electrical Drive Laboratory (Laboratório de Eletrônica de Potência e Acionamento Elétrico – LEPAC, in portuguese) at the Federal University of Espírito Santo (UFES), Brazil. The dataset was generated from a computer simulation of a three-phase squirrel cage induction motor model with the insertion of faults in the rotor, specifically broken bars. The induction motor mathematical model with broken bar fault is based on reference [1].

An experimental study was conducted on a high-voltage glass-type disc (LD-160) to investigate the effect of string arrangements on pollution and icing flashover characteristics. Two Artificial Neural Network (ANN) applications were developed to simulate and calculate the flashover voltage based on the experimental results. The test results showed that the inverted T-type arrangement can improve the pollution flashover voltage and increase the icing flashover voltage of insulator strings compared to the traditional arrangement of the I-string.

Due to the diversity of battery types and capacities, wireless power transfer (WPT) systems for autonomous underwater vehicles (AUVs) have large variations in charging voltages and currents. Conventional solutions of using DC/DC converters to adapt to different specifications may cause increased cost and volumeand reduced overall efficiency. To address this issue, this video presents a new AUV WPT system with DC-link series/parallel AC-link parallel rectifiers for different charging voltages and currents.
