A back substitution circuit is shared at the first and third phases. A high-speed vector-dense-matrix multiplier is well designed for the second phase, which offers tradeoffs between speed and memory. The proposed encoding method just removes some nonzero circulants of a sparse parity-check matrix $pmb{H}$. while the classical Richardson-Urbanke (RU) approach splits $pmb{H}$ into multiple submatrices and destroys its integrity. It is shown that the proposed encoder runs fast, has low complexity, and is well compatible with multiple code rates.","PeriodicalId":6573,"journal":{"name":"2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"48 1","pages":"1189-1193"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88715402","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 existing seam feature information extraction technology has a good effect on thin plate, but its extraction accuracy is low when dealing with thick plate and deep weld groove. Based on the point scanning laser sensor, a method of image information preprocessing and feature extraction for thick plate is proposed, and the related algorithms are optimized. Aiming at the common right angle and oblique inflection point in the weld groove, the slope extreme value method and the oblique intercept method are used to extract the weld seam feature points respectively. Finally, the effectiveness of the proposed algorithm is verified by experiments.","PeriodicalId":6573,"journal":{"name":"2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"9 1","pages":"1538-1542"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89366226","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}

However, processing data measured by extra equipment on the machine tool are all in time dimension, while cutting position parameters of the machine tool are in spatial dimension. Thus, there is no one-to-one correspondence between the monitoring data and cutting position, which is inconvenient to research various coupling relationships of the workpiece in machining process. This paper presents a time-position mapping method for the monitoring data and the cutting position, where data are collected by the acquisition device and the data acquisition software in the same frequency. Time zeroing at the marked position synchronizes the data acquisition processes in time dimension, which realizes the time-position mapping between the monitoring data and the cutting position. Based on Siemens 840D numerical system, linear and curvilinear motion milling experiments with different feed rates verify the accuracy of the collected data from the acquisition software. Boss with different heights cutting experiments show the correctness of the time-position mapping between the monitoring data and the cutting position.","PeriodicalId":6573,"journal":{"name":"2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"24 1","pages":"1281-1287"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87031609","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}

We put forward the boundary condition by the force analysis of the actual physical model, and establish the integral equation on the boundary crack L°, + L1 by using the D.I. Sherman method, which is based on the relevant elastic mechanics knowledge. Then by inverse transformation the original problem is reduced to the singular integral equations on crack L1, which is discreted by using the Gauss formula afterwards, to get the numerical solution of it. Finally, we use MATLAB to simulate the numerical solution to get the trend chart of the crack displacement, which is affected by external force and crack inclination angle. It intuitively shows the change rule of crack and all parameters.","PeriodicalId":6573,"journal":{"name":"2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"65 1","pages":"2482-2486"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90725047","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 people hear their favorite music more accurately, various recommendation algorithms emerge one after another. KNN is one of the best neighboring algorithms based on collaborative filtering. However, when the ratings that from the users' changed, the error rate of the KNN recommendation algorithm is higher. In this paper, we point the disadvantages of the KNN algorithm that is greatly affected by the rating. And then we propose the improved algorithm KNN-Improved which is based on the KNN algorithm and makes use of the mean value's thought of the Baseline algorithm, besides, we add to the standard deviation of the rating. These measures can effectively reduce the impact of too high or too low about user ratings, reduce the error rate of the recommendation algorithm, and then achieve better recommendation results. Finally, different recommendation algorithms are compared for performance and improved algorithms are applied.","PeriodicalId":6573,"journal":{"name":"2018 IEEE 3rd Advanced Information Technology, Electronic and Automation Control Conference (IAEAC)","volume":"23 1","pages":"777-781"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90832299","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}
