The presented technique combines the merits of hyperbolic tangential sliding surface (HTSS) and adaptive neuro-fuzzy inference system (ANFIS). The HTSS not only has the robustness of classic SMC but increases the system trajectory convergence speed. However, once a highly nonlinear load occurs, the chattering still exists. The chattering causes high total harmonic distortion (THD) in DC-AC power converter output voltage, thus yielding the instability and unreliability of advanced material machining. The ANFIS is thus employed to eliminate the chattering and simultaneously the HTSS provides finite system-state convergence time. By combining HTSS with ANFIS, the DC-AC power converter of AMM will achieve robust performance. Experimental results are given to conform that the proposed technique can obtain low total harmonic distortion (THD) and fast transience even under phase-controlled loads. Owing to the notable superiorities, e.g. computational quickness, practical simplicity, and programmable easiness in the proposed technique, this paper will be a helpful reference to researchers of related advanced material machining.","PeriodicalId":239044,"journal":{"name":"Journal of Automation and Control Engineering","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130388929","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 have focused on the static analyses of software systems with the function-call graph and empirically found them to reveal small-world, scale-free features similar to those identified in sociological and technological systems. Another crucial step when studying the structure of networks is to identify communities. Most existing approach to this problem in the previous literature simply ignored the edge direction and applied methods for community detecting in undirected networks. In this paper, we consider the problem of finding communities in directed weighted networks and develop a new community detection algorithm for the networks. Our method regards communities as groups of links rather than nodes in contrast to the existing detection algorithms. This algorithm is tested on function-call graph of artificial system and our experiment is shown to finding communities on the test directed weighted network successfully.","PeriodicalId":239044,"journal":{"name":"Journal of Automation and Control Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127750067","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}

After each learner issues a short text post on the online discussion platform, a feature selection approach is adopted to derive the input parameters of a Support Vector Machines (SVMs) classifier. The classifier then determines if the learners’ posts are related to the concept maps previously outlined by the instructor. Notably, a feedback rule construction mechanism is used to issue feedback messages to learners in cases where the online short text assessment mechanism detects that the learners have strayed astray from the expected learning topics in their posts.
