Here, an error detection and correction method of TIADC based on genetic algorithm (GA) optimization is presented. The algorithm based on sine fitting is used for the first estimation and rough correction of the input signal, and GA is used for the second detection and fine correction of channel mismatch errors on the signal after frequency domain filtering. Experimental results show that the SNDR of the TIADC system is enhanced to 92.24 dB, the SFDR is enhanced to 102.05 dB, the ENOB is enhanced to 15.03 bits and the spectrum spurs are reduced. This method provides a new idea for error detection and correction of high-resolution TIADC systems with more than 16 bits.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130237552","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}

Although China’s entrepreneurial education in the past ten years has achieved certain results, the current situation of college students’ entrepreneurship is still not satisfactory. Although in recent years, there are more logistics graduate students in various higher vocational colleges, it is still difficult to meet the logistics enterprises’ demand for logistics talents. We Can combine entrepreneurship education with higher vocational education. Uniting “employment education” with “entrepreneurial education”, “employment skills” and “entrepreneurial skills” can better cope with the new challenges facing higher vocational education. Based on this, this paper establishes the evaluation index system of logistics talents quality in Higher Vocational colleges, and on this basis, uses the analytic hierarchy process to evaluate logistics talents in Higher Vocational colleges. Through the evaluation of logistics talents in Higher Vocational colleges, we can find the existing problems of logistics talents in Higher Vocational colleges, which has certain guiding significance for improving the quality of logistics talents in Higher Vocational colleges.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122128418","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}

The nonlinear model predictive control method was used to solve the collaborative obstacle avoidance problem, and the specified UAV behavior pattern was used to shear the search space to improve the search efficiency of the method.

The IRE treatment method is to place a minimally invasive needle electrode in or around the target area to generate a series of short electrical pulses. This therapy uses electrical pulses to generate an external electric field to change the transmembrane potential of the cell membrane through a non-thermal mechanism, which can irreversibly destroy tumor cells. The effect of IRE treatment on the tissue is related to the distribution of the electric field in the tissue, which depends on the pulse parameters used and the conductivity of the tissue. We built a conductivity measurement system for porcine liver tissue based on a pulse signal generator, and tested the conductivity change of porcine liver tissue due to the electroporation effect of cells. We fitted the experimentally measured conductivity to the applied pulse intensity and got good results. The measurement system built in the experiment is simple and easy to use. Our accurate measurement of conductivity under different pulse width and electric field intensity can effectively improve the accuracy of the numerical model in the treatment planning.","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130955743","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}

Reusing the channels is an excellent way to reduce the cost, but it also causes interferences. Therefore, optimising the methods of the allocation remains critical. This paper shows that the combination of Simultaneous Water-Filling and Fractional Frequency Reuse with specific reuse factors of Integer Frequency Reuse applied to the centre part of the cells performs compellingly. Besides, the reuse factor should be chosen carefully to avoid both interference and the separation of total power. The results demonstrate how Simultaneous Water-Filling works and how the reuse factor plays a role in preventing disturbances among multiple base stations. The result shows, in Fractional Frequency Reuse network, the method with Simultaneous Water-Filling is always better than that without it. Besides, the combined method works well when the reuse factor is low (being 1) or high (being 7), but not good when the reuse factor is medium (being 3).","PeriodicalId":219763,"journal":{"name":"2021 International Conference on Electronics, Circuits and Information Engineering (ECIE)","volume":"170 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116627736","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}
