Through the jet simulation of three standard nozzles with different outlet sizes under different boundary conditions, the relationship between outlet diameter and boundary conditions and jet turbulence intensity and near-field and far-field noise is studied. The simulation results show that the outlet cross-sectional area affects the value and range of the turbulence intensity, and has a great change in the mixing region of the turbulent boundary layer. However, under the excitation of the sound source quadrupole, it has no great impact on the propagation trend and extreme value of the sound wave.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134378799","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}

This paper proposes an improved network based on YOLO-lightweight. The attention mechanism module is embedded in the backbone network, focusing on the important features from different channels. CBAM-FPN (Convolution Block Attention Module and Feature Pyramid Networks) structure is adopted in the network neck to reduce the loss of network features. Attention mechanism module is added in the bottom-up feature fusion process. Finally, CIOU is used as the edge optimization loss function to accelerate the network convergence and optimize the network model. Compared with YOLOv4-tiny, the precision is improved by 3.8%, reaching 87.5%. The detection speed reaches 60.3fps. The improved network only occupies 23.4M memory, which is convenient for embedding mobile devices. The improved network meets the real-time detection requirements.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130582778","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 paper, we propose an extended event graph named Probability Event Graph (PEG) to predict the opponent’s future events. Compared with the basic event graph model, the element of event node, logical node, causal edge and time window is redefines in PEG. Through these novel elements, PEG can describe the event and causal relationship about the system comprehensively. The PEG model is the fundamental of forecast analysis. Firstly, the behaviour characteristics of opponents are analysed and the corresponding PEG model is established according to domain knowledge. Then, the parameters are acquired by training data generated by simulation. Finally, the reasoning algorithm based on PEG model is proposed, and the possibility and principal analysis are carried out.","PeriodicalId":290902,"journal":{"name":"International Conference on Mechatronics Engineering and Artificial Intelligence","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122337790","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, the finite element model (FEM)of shell-rod structure was established, and the feasible direction method (MFD) was used to optimize the wing structure size.

It is difficult to obtain the relationship between mud transportation concentration and pumping hatch, mud pump, high-pressure flushing, submarine diversion valve and pipeline through mechanism analysis. Aiming at this problem, this paper proposes a prediction method of instantaneous output of trailing suction dredger pumping and bank blowing based on BP neural network. Through the training of historical construction data, PSO and GA algorithms are used to optimize respectively, and the prediction model of instantaneous output of trailing suction dredger pumping and bank blowing is established.

The data model of Modbus is built by object-oriented technology. According to the principle of hierarchical semantic equivalence, the mapping relationship of information and service models among Modbus, IEC61850 and MMS is established.
