Title: A Novel Signal Processing Method of Coriolis Mass Flowmeter Based on SVR and Hilbert Transform

Abstract: The traditional Coriolis flowmeter signal processing method obtains the mass flow by calculating the time difference. However, in the actual measurement, noise and changes in the surrounding environment will affect the accuracy of the mass flow measurement. To improve the measurement accuracy of mass flow and reduce the impact of noise, a novel signal processing method for Coriolis mass flowmeter based on SVR and Hilbert transform is proposed in this paper. The Hilbert transform is performed on the vibration signal obtained by the sensor firstly, the phase difference extracted by the Hilbert transform and the mass flow of the standard meter are used as the sample feature and the label value respectively to build the support vector regression machine model. Apply the trained model to the test set to make predictions on the data. The test result shows that the mean square error of the prediction result obtained by this algorithm is 1.0003E-03, which is better than 3.937E-03 of the checked meter.

Title: Research on acoustic emission intelligent monitoring in grinding engineering ceramics

Abstract: Acoustic emission (AE) signal analysis by use of short time Fourier transform is used to monitor the grinding heat by ues of laser. The relationship between the acoustic emission signal of high speed grinding of engineering ceramics and grinding force, grinding temperature are studied. High precision AE monitoring of diamond grinding wheel wear in engineering ceramics grinding were carried out. The variance of wavelet decomposition coefficient of AE signal in alumina grinding is used as the input feature of support vector machine. The empirical mode decomposition (EMD) of grinding AE signal is used to extract the effective value, variance and energy coefficient of its intrinsic mode function as the input features of least squares support vector machine. The convolution neural network is used to monitor the grinding surface roughness by use of AE. The research solved the problem of acoustic emission monitoring in engineering ceramics grinding!

Title: ReseaSwarm intelligence optimization: advances in algorithms and applications

Abstract: The traditional deterministic methods produce unsatisfactory solutions in solving complex real-world problems. Swarm intelligence optimization algorithms (SIOAs), inspired by the collaborative behavior of organisms, have provided encouraging results for solving complex optimization problems. In this talk, I will introduce the current popular SIOAs and a novel technique called Remora Optimization Algorithm (ROA). Analyzing their search mechanism and existing limitations in different optimization tasks. In addition, I present a series of studies we have undertaken to address these challenges.
