    DAMAGE IDENTIFICATION OF BEAM STRUCTURE BASED ON HYBRID NEURAL GENETIC ALGORITHM by WANG MingYue, MIAO BingRong, Li XuJuan, YANG ZhongKun

    Published 2017-01-01
    “…It has established that a crack has an important effect on the dynamic behavior of a structure.To identify the location and depth of a crack on a structure,a method is presented which uses hybrid neuro-genetic technique.This method combines genetic algorithm(GA) with neural network,and uses genetic algorithm to optimize the BP network.Though the finite element analysis,acquire the first three natural frequencies of the beam,which used as inputs into neural network models for damage assessment.Genetic algorithm(GA) optimizes the weights and thresholds of the network,and using the optimization results as the initial value of the three layer BP neural network.Though the training of the sample data,then establish the suitable network.Finally,using the theoretical natural frequencies as the test values,obtain the predicted results of crack parameters.Comparing the theoretical value with the predicted value,the results show that this algorithm can identify the damage structure accurately.…”

    Coordinated air-ground scheduling for UAV-assisted cell-free massive MIMO by Danhao DENG, Chaowei WANG, Fan JIANG, Weidong WANG

    Published 2022-08-01
    “…Cell-free massive multiple-input multiple-output (MIMO) technology uses a large number of access points (AP) to provide efficient communication services for terrestrial users.However, massive APs and users increase the demand for channel state information detection, especially for users with high moving speeds.In order to reduce the consumption of pilot resources, a dual system architecture that integrates unmanned aerial vehicle-assisted (UAV-assisted) communications and cell-free massive MIMO communications was proposed.The architecture was able to predict the movement trajectories of high-speed users and use UAVs to provide them with reliable communications.A UAV trajectory design and user scheduling scheme based on deep reinforcement learning (DRL) was further proposed, which maximized the system sum rate under the premise of satisfying various constraints.Simulation results demonstrate that the proposed scheme is able to predict user trajectories and improve system sum rate compared with existing schemes.…”

    An adjustment method for electricity sales forecasting result considering the effects of spring festival by Jian LIU, Jiakui ZHAO, Yuze CHEN, Xuemin FANG, Yuxi LIU, Shulong WANG, Yan CHEN, Hong OUYANG

    Published 2019-03-01
    “…The effects of Spring Festival on electricity sales of different trades were considered and an adjustment method for electricity sales forecasting result was proposed.Firstly,the month-quarter ratio of historical electricity sales in each trade of every month in the first quarter and the distance between Spring Festival and the first day of every month in the first quarter was used to create a functional relationship.Then,the distance between Spring Festival and the first day of every month in the first quarter of the target year was used as input and the predicted month-quarter ratio of electricity sales of each trade of every month in the first quarter of the target year was calculated according to the functional relationship.The adjusted electricity sales forecasting result can then be computed by using the predicted month-quarter ratio and the electricity sales forecasting of each trade of every month in the first quarter of the target year before adjustment.The adjustment result shows that the proposed method can effectively lower the error of electricity sales forecasting in the first quarter.…”

    Application of Grey Self-Memory Model Based on Smoothing Method Without Seasonal Fluctuations on Monthly Runoff Forecast by WAN Yang, YANG Haiyan, TANG Jingjing

    Published 2021-01-01
    “…Affected by the monsoon climate,there are abrupt changes,non-smoothing and variation in monthly runoff.However,good accuracy cannot be realized if the monthly runoff is simulated and predicted directly by the gray self-memory model.This paper proposes a new monthly runoff smoothing method (that is,smoothing method without seasonal fluctuations).First,the seasonal index is used to remove the “seasonal fluctuations” of monthly runoff,then,the three-point smoothing method is applied to smooth the monthly runoff without seasonal fluctuations,and finally the gray self-memory model is adopted to simulate and predict the smoothed data.After being applied to the Yanling Hydrological Station in Hunan Province,the results show that the average error of fitting and forecasting value of monthly runoff after seasonal fluctuation removing and smoothing is less than 20% compared with the measured value.At the same time,the short-term monthly runoff data is used to simulate and forecast monthly runoff by this method,which also meets the requirements of the specification.…”
