The paper studies the multi-objective optimization task resource offloading algorithm for edge terminal server, such as computing power, service time, bandwidth, memory and so on. Firstly, the offloading model of edge computing resources for multi-objective optimization is proposed. On this basis, an improved genetic offloading algorithm is proposed to reduce the probability of population algorithm falling into local optimum by self-adaptation coefficient and factors of age and longevity. Meanwhile, the probability of finding the optimum solution is improved.

Based on that, the time-frequency eigenvalue boundary for identifying different bushing defects is constructed, and the bushing state diagnosis method based on the time-frequency characteristics of spectrum is proposed according to the distribution results of the Teq - Feq graph.

In order to cope with the difficulty of identifying the faulty reflected wavefront caused by TW attenuation and noise interference, a TW wavefront detection method using progressive kurtosis is developed to capture the precise arrival time of the reflected wave, which can significantly eliminate the influence of false wave head calibration existing in conventional methods. The correlation coefficient is used to compare the polarities of the initial and the second reflected TWs, so as to identify the source of the second reflected wave, and thus identifying the faulty segment. Finally, the precise fault distance can be calculated through the appropriate TW fault location formula.

Air cooling and liquid cooling are two common solar PV/T cooling solutions. The air-cooled PV/T system has numerous variables, and the heat transfer mathematical model is quite complicated. The BP (Back Propagation) neural network method can be used to create a simulation prediction model, which can be used to simulate and predict the thermal and electrical performance of a solar PV/T system. The simulation is based on data from a single-day experiment conducted during the heating season, and it records the BP neural network's six types of temperature difference prediction and electric power prediction under various input parameters (groups 2-group 4-group 6). The appropriate level of training has been attained. The electrical and thermal efficiency of PV/T systems can be calculated using these BP neural networks. The fitting degree of the anticipated value and the actual value of the BP neural network model fulfils the requirements when compared to the experimental data gathered over two days and the prediction results of the BP neural network model. On the two projected days, the prediction accuracy R2 of electric power value were 0.97009 and 0.95538, respectively. The temperature difference numerical fitting degree is somewhat worse than the electric power value. The R2 values were 0.90114 and 0.93547, respectively, for forecast accuracy.
