Structure balance theory studies the unbalanced relationships in signed networks. The computation of structural balance aims to search for the least unbalance degree of a signed network to transform an unbalanced network into balanced one with the least cost. In this study, under the weak definition of structural balance theory, a node influenced memetic algorithm, called NIMA, is proposed to minimize the objective function. There are three main parts in NIMA. Firstly, a neighbor node influence-based initialization operation is applied to create an initial population for speeding the convergence process. Secondly, a node degree-based genetic operation is employed as the global search method. Moreover, a multi-level greedy local search is adopted to approach the potential optimum effectively. Extensive experiments on 9 real-world signed networks demonstrate that the proposed NIMA performs more efficiently, compared to other classic algorithms, on computing the structural balance of signed networks.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126821370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a MPPT torque controller is designed for variable-speed wind turbines (VSWT) based on the bounded uncertainty and disturbance estimator (UDE). First, the optimal rotor speed is calculated according to the relationship between the wind turbine's power coefficient and the tip speed ratio. Based on the dynamic model of VSWT, a torque controller based on UDE, which can eliminate the control deviation caused by the uncertainties and disturbances, is designed. However, traditional UDE control have integral phenomenon, which will affect the tracking performance and even causes the system to run out of control. To deal with this, a bounded UDE torque controller along with a time-varying constraint coefficient is developed. It can avoid the integral windup issue caused by the input torque of the VSWT exceeding the maximum boundary of the actuator, and achieve a more stable optimal speed tracking performance. Finally, the effectiveness of the proposed MPPT torque controller is verified through the FAST (Fatigue, Aerodynamics, Structures, and Turbulence) platform.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130613190","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the development of intelligent detection technology, as the state of the art model, target detection model based on deep neural network adopts different scale feature extraction mechanism, which is easy to generate false alarm for important targets and difficult to overcome the contradiction between false detection and missed detection. The attention mechanism can fully learn the features of the target and improve the accuracy of target detection. Considering the characteristics of seabed exploration task and underwater target, we propose a deep convolution network based on dual channel attention mechanism (DCNet), This model can strengthen the features of the target of interest while weakening the irrelevant background noise information, so as to improve the detection accuracy of the target and enhance the detection ability of the underwater target. The experimental results show that the average accuracy of the dual channel attention mechanism can achieve higher accuracy than the original model, and is superior to other target detection models in accuracy and performance. This research has important practical significance for improving the task of underwater target detection of sonar images and has a wide range of engineering application prospects in the detection of underwater acoustic systems.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132715179","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clustering algorithm is a kind of unsupervised learning algorithm. Although many clustering algorithms have been studied in modern science and applied in many fields, it is their common problem that the quantity of clusters has to be specified. Based on EM algorithm, this paper proposes a cluster centers learning algorithm (CCL) which can self-adaptively calculate the quantity and parameters of clusters according to the characteristics of samples themselves. The algorithm tentatively fills the shortage of existing clustering algorithms. The paper proposes the elementary merger and splitting criteria. The criteria can determine whether a point is the cluster center according to the characteristics of samples. Based on the elementary criteria, the algorithm proposed by the paper can adapt to calculate the correct quantity of clusters and gives the corresponding clustering parameters. Monte Carlo simulation is used to evaluate the effectiveness of the proposed algorithm. The experimental results show that the algorithm proposed by the paper can start from an arbitrary given cluster center and calculates the cluster centers close to the actual cluster centers of the samples themselves, so as to complete the self-adaptive unsupervised clustering.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127103092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking the baggage palletizing experiment platform as the application scenario, the trajectory of the pick-up segment for accurately picking up the baggage with the pallet is planned. The 4-3-4 polynomial interpolation method is used to plan the trajectory of the placement segment, and MATLAB is used to simulate the trajectory. The simulation results show that the planned trajectory is smooth and continuous, there is no major impact during operation. Finally, the multi-ob-jective particle swarm optimization (MOPSO) algorithm is used to optimize the trajectory with the target of trajectory running time, luggage pallet motion impact and angular acceleration. Field experiments in the laboratory show that the actual trajectory of the robot is basically consistent with the planned trajectory. The optimized trajectory running time is less than 7 seconds, the trajectory running is stable. The angular acceleration distribution of each axis is relatively uniform, which can realize the accurate retrieval and stable placement of baggage, and effectively improve the accuracy and efficiency of baggage pick-up and placement.","PeriodicalId":211213,"journal":{"name":"2022 12th International Conference on Information Science and Technology (ICIST)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116525172","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
