In this context, the study proposes a modeling method of thermal error compensation for the displacement of the cutter position. In the X-direction, the mechanical structure is closer to symmetrical form, which evenly distributes the thermal energy, so the thermal error is always small. Therefore, this study only deals with the thermal error in the Y and Z directions. The explanatory power improvement of the multiple regression model largely depends on the feature selection. The paper proposes the backward elimination (BE) algorithm base on mean squares of K-fold errors minimization as feature selection of multiple regression model to establish thermal error compensation modeling. Firstly, BE fits the complete model with all features, and then deletes the feature one by one using the selected test criterion until deleting any feature cannot improve the model explanatory power. The K-fold Cross Validation (KCV) evaluates model performance in limited training data and be used as a criterion for model selection. KCV cut the data into K subsets to keep k-1 subsets as model training, and the remaining subsets as model validation. The procedure is repeated k-times until the last subset is set as the validation set, then the average error across all k trials is computed. To evaluate each feature to be eliminated through KCV, the smallest mean squares error is selected from the N results to determine the variable for elimination each time, where N is the number of features. The multiple regression model was established by using the features selected for the Y and Z axes. Test results show that the method can reduce the peak-to-peak value of thermal error from about 55 μm to below 14 μm in the Y direction, and in Z direction is from about 74 μm to below 19 μm.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130512783","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}

Thus, continuous management is necessary. Recently, the automated anomaly detection system is adopted for reducing human exhaustion. Moreover, for improving the cost-effectiveness and monitoring stability, edge device computing is considered on system construction. For enabling edge computing, we need to achieve high performance with a low-complex anomaly detection model, considering the constrained resource. In this paper, we empirically evaluate various anomaly detection architectures from two perspectives for designing a cost-effective model. One of the perspectives is the feature aggregation method and the other one is whether to adopt the bottleneck structure or not for constructing autoencoder. The effectiveness and efficiency are improved by adopting linear feature aggregation and non-bottleneck structured auto-encoder. By combining the above two methods, the computational cost is reduced by 2 in 10k, while losing only 1.972% of the averaged anomaly detection performance.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"254 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121324980","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, The heat transfer enhancement and the pressure drop were investigated using CFD to obtain an optimal compromise between the temperature uniformity and the pressure drop gain. It was found that a helix length of 40d is an optimal compromise between the temperature uniformity and the pressure drop gain. In this paper, another two important parameters regarding the operation of an SFT, the helix amplitude and the helix pitch are investigated to get a more thorough understanding of the SFT performance. The pressure decreases to a larger extent for a larger helix amplitude and the pressure drop is nearly proportional to the helix amplitude. In addition, the temperature increases with the helix amplitude, and the improvement in temperature uniformity index enhances with increasing helix amplitude. Concerning the influence of the helix pitch, the pressure decreases to a larger extent for a smaller helix pitch and the pressure drop is nearly inversely proportional to the helix pitch. The temperature decreases with the helix pitch and the improvement in temperature uniformity index are enhanced by decreasing the helix pitch.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121669702","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 designing the security control scheme, there is one critical requirement taken into consideration for minimally changing the original configuration of SCADA systems. To validate the feasibility of the proposed security proxy approach, techniques for protecting the privacy and integrity of Modbus protocol messages are implemented in the proxy functions. Advanced encryption system (AES) is adopted by the proxy function to encrypt the messages before transmitting to prevent commands or data from being interpreted easily. In addition, the hash function is employed to generate an authentication token to make sure the received message is the same as the sender sent. The extra processing delay time required for each Modbus message after passing through the proxy functions is treated as the important factor for the success of the proposed approach in SCADA systems. Based on the experiments with replay and man-in-the-middle (MITM) attacks, satisfactory results are obtained, demonstrating the usefulness of applying the proposed security approach to network-based SCADA systems.","PeriodicalId":176225,"journal":{"name":"2021 IEEE 3rd Eurasia Conference on IOT, Communication and Engineering (ECICE)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115450473","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}
