Abstract This paper proposes a wavelet-based data compression method to compress the recorded data of oscillations in power systems for wide-area measurement systems.Actual recorded oscillations and simulated oscillations are compressed and reconstructed by the wavelet-based data compression method to select the best wavelet functions and decomposi
Wear analysis has been carried out on aluminum tube in parallel triangular tube bundle with P/D ratio of 1.45 and the baffle plate placed at the mid-span of the bundle.The cross-flow velocity of water ranges from 0.18 m/s to 0.55 m/s.For each flow velocity, tests were performed on five different flow velocities and three-time spans (tube-baffle int
