The solution consists of several stages. The clustering is a critical step. The clustering of feature points of the image is consuming and important step that needs to simplify and speed up. For this task, it is proposed to use the properties of a random walk on the graph. The random walk can lead to a measure of cluster cohesion. This approach is closely related to spectral graph theory. The paper presents formulas, steps of the algorithm and an example of calculations. Experiments and comparisons are made with the closest analogue, the method of normalized cut.","PeriodicalId":423038,"journal":{"name":"2015 International Conference on Mechanical Engineering, Automation and Control Systems (MEACS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127764607","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 the basis of the energy approach developed a mathematical model describing the mechanism of relaxation of residual stresses in the ring parts in the multicyclic loading. This model takes into account the geometrical dimensions of the part, physical and mechanical properties of the material and technological modes of processing. We received an analytically expression defining vibro-mechanical processing time, required for the complete removal of residual stresses in the ring parts. It has been established that exceeding the specified time leads to an accumulation of residual stresses until the onset of destruction of products. Experimental studies that describe the change in the internal stress in the multicyclic loading are conducted.","PeriodicalId":423038,"journal":{"name":"2015 International Conference on Mechanical Engineering, Automation and Control Systems (MEACS)","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133580394","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}
