In this study, based on the field emission theory and using carbon nanotubes as the cathode material of electron gun, the calculation method of the threshold value of open voltage on the surface of carbon nanotubes is proposed, and a model of electronic optical lens for four electrodes structure are constructed. By using multiple physics simulation software COMSOL, the structure parameters such as the distance between the deceleration lens and the anode, the thickness of the deceleration lens, the radius of the deceleration lens and the electrical parameters such as the voltage of the anode are simulated in this paper. According to the results, the divergence angle of the electron beam can vary from 18° to 33° by optimizing the structure parameters of the deceleration lens, and the energy of the electron beam is continuously adjustable in the range of 110 eV-135 eV. In addition, by adjusting the anode voltage, the divergence angle of electron beam can be further varied from 12° to 37° and the energy of electron beam can be continuously adjusted in the range of 95eV-145eV.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126474208","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}

Therefore, a self-developed strain gauge cutting force sensor is employed for cutting condition monitoring and machining quality analysis in this paper. Experiment results show that the cutting force sensor is able to measure dynamic cutting force reliably, and the measured cutting force can accurately reflect the changes of cutting parameter and cutting condition. Characteristic signals for reflecting machining quality and representing are also found in the cutting force data. The influence of cutting force on cutting vibration and surface smooth as well as cutting fault is preliminarily clarified. It proves that cutting force can be effectively used for monitoring cutting condition, optimizing cutting parameters and predicting cutting faults.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"133 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122760219","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}

Most existing pruning methods use threshold-like parameter to control the effects of pruning. Such approaches usually encounter difficulties in parameter tuning and the quality of pruning. A skeleton pruning method is proposed in this work. This method decomposes a skeleton into a number of skeletal components (SCs), and the terminal SCs are removed one by one according to a saliency measure. SCs may be merged into a new one after each removal. The removal process continues until the desirable number of terminals are achieved. The method can essentially be regarded as the sorting of the terminals, and the truncation of the terminals at the given number. This method is suitable for applications where the desired number of terminals can be determined a priori. Experimental results show that the method can effectively prune the skeletons from the test image bases, and it has the advantage that the terminal number parameter is very intuitive and easy to set for the applications under concern.","PeriodicalId":419168,"journal":{"name":"2019 14th IEEE International Conference on Electronic Measurement & Instruments (ICEMI)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126389537","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 3D finite element model of a 3mm deep-defective pipe was created for the artificial flaw on the inner wall of the 20# steel pipe. The fitting analysis of the corrosion defects data at different depths of the inner wall was performed by MATLAB. The polynomial relationship curves of the coil impedance and the corrosion defects at different depths were obtained. It was observed that both the amplitude and phase of the impedance exhibited a smooth and decreasing trend with the increasing of the corrosion depth.

Then, the applicability of GUM method is verified by the method given in JCGM 101:2008 GUM supplement1, and it is concluded that the GUM method is still applicable to the evaluation of uncertainty in the wind speed measurement of pitot tube.
