A distributed adaptive control law is designed to identify the external environment, and the parameter convergence and the parameter consensus are achieved. The cooperative control law is easier to satisfy the persistently exciting condition. Using the containment control approach, a distributed control law is proposed to guarantee that the trajectory error and the parameter errors are uniformly ultimately bounded. The effectiveness of the proposed adaptive control laws is demonstrated by some simulation examples.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"09 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127457985","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}

On this basis, an LVQ neural network assisted integrated navigation fault detection method is developed for LVQ (Learning Vector Quantization) networks with few design parameters, simple network structure and non-normalized input vectors during usage. The optimal number of neurons in the competitive layer is determined by K-CV (Cross Validation) verification method, and LVQ neural network is used to identify and classify the soft and hard faults added at different times. The simulation results indicate that compared with traditional neural network, LVQ neural network achieves higher detection accuracy (93%) with lower CPU usage. Thus, it is convinced that the study has great engineering significance and practical value.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128914121","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}

Avoiding secondary injury to patients has become the core indicator of medical care quality evaluation. Falls are the most common and most dangerous behavior of children in hospital. And vision based abnormal action detection of children in wards is very challenging because of the unnoticeable appearance and the complex ward environment. Previous approaches achieve anomaly action detection in urban and industry by the skeleton of human. However, they cannot effectively detect and alarm abnormal actions of hospitalized children in the ward, because their model or Kinect cameras cannot obtain the accurate skeleton of the child in real time. In this paper, we propose an intelligent video surveillance system aimed at detecting and alarming abnormal actions of children in wards. Experimental results demonstrate that our system achieve 85% accuracy in detecting and alarming abnormal actions of children in wards, and our system can process information from two beds simultaneously with a speed of 12ms per frame. The daily video data of children in the ward is also saved locally, which is exceedingly useful for augmenting risk action datasets of hospitalized children. In the future, we will improve our proposed system by obtaining state information of children, thereby reducing the false positive rate of the system.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132009332","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 order to make this event-triggering method applicable to hybrid multi-agent systems, especially discrete time dynamics agents, the definition of hybrid combined measurement and its error is updated in this case. Then we apply simulation experiments to confirm the validity of this event triggering method.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134277979","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}

Existing studies mainly analyze word-of-mouth in tourism from internal factors (service level, price, facility condition, etc.), and there is a lack of extended studies focusing on external factors, e. g. the spatial distribution of tourist accommodations. Based on the Point of Interest and User Generated Content information of 71 accommodations around Chengdu Research Base of Giant Panda Breeding, this paper uses social network and sentiment analysis tools to filter relevant variables affecting word-of-mouth. Spatial econometric models are then built and examined, and we further identified the optimal model to discuss the key factors affecting word-of-mouth in the accommodation industry from the perspective of spatial distribution. Results show that: (1) there is significant spatial clustering and spillover effect of word-of-mouth in the study accommodations. (2) network structure has a significant impact on word-of-mouth, which enables reference for site selection. (3) the improvement of service level and geographical location of tourist accommodation has a significant positive effect on word-of-mouth.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133554066","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}

Different preparation methods have a great impact on the efficiency of shunting operation, therefore, mainly studying the preparation method of shunting Plan in depot in this paper, i.e. the plan is obtained by the Binary Sorted Tree (BST). Firstly, the BST in line with the shunting of the depot is established; Secondly, the shunting scheme is obtained by traversing the established BST, and the scheme is screened and evaluated to obtain the optimal scheme; Thirdly, using the computer simulate the collection process and generate the shunting plan.

First of all, the task of maritime oil spill emergency monitoring and the monitoring subjects carrying out the tasks are identified, and the specific types, difficulties and risks of the tasks are identified. Then, the task type is introduced to indirectly express the relationship between ‘monitoring subject-task’. On this basis, two concepts of task demand satisfaction and emergency monitoring subject capability competency are proposed to express the preference information of bilateral subjects. And then on the basis of redefining the specific connotation of the basic concept of bilateral matching theory under the background of maritime oil spill emergency monitoring task allocation, a bilateral matching model for task allocation of maritime oil spill emergency monitoring considering attribute priority is constructed. Finally, according to the specific characteristics of the model, a fast generation algorithm of feasible solution is designed to solve the problem. The model proposed in this paper standardizes the task allocation process of emergency monitoring in reality and plays an auxiliary role in improving the efficiency of emergency monitoring.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121881731","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}

A novel definition about bipartite containment is given to show that agents in different groups will reach different coordination, respectively.

To solve this problem, a novel robust control approach is proposed, consisting of a constrained controller and an integration compensator. The former is used to confine the internal errors within the predefined sets, against the model uncertainties and disturbances. The latter works during the DoS attacks to reconstruct the position information. In this way, the satisfactory dynamic positioning performance of the MSVs is guaranteed. Moreover, the control simplicity is preserved, i.e., there is no need to employ specific tools to approximate the model uncertainties, to estimate the disturbances, or to observe the system state. The simulation results on Cybership II illustrate the effectiveness of the proposed control approach.","PeriodicalId":348545,"journal":{"name":"2022 4th International Conference on Data-driven Optimization of Complex Systems (DOCS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128747859","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}
