Condition Monitoring of VSD-fed Induction Motors by Ralikalakala, Lebohang

“…A similar trend is observed in speed and torque pulsations of the motor under the respective faults. Similarly, the method of diagnostic variables has proven valid for both simulation and experimental results and is able to detect and localise inverter open switch fault for single and double switch fault. …”

Efficient radio resource management in integrated terrestrial and non-terrestrial networks by Birabwa, Denise Joanitah

“…Moreover, the multi-agent deep Q network (MADQN) solution is also simulated as an additional benchmark algorithm. Simulation results reveal that as the number of users in the network increases, the acquired data rate of the MA3DQN is within 0.48% and 0.42% of that achieved by the GA and ILP, respectively, and outperforms all other algorithms. …”
