However, one of the fatal shortcomings of traditional ART-2 is that its final results heavily depend on a pre-defined fixed vigilance threshold parameter, which makes it infeasible to be applied in different complicated applications. Another disadvantage of traditional ART-2 method is that the number of categories in the network will increase all the time with the continuous input. Considering these points, an improved algorithm of ART-2 has been presented in this paper called the Robust ART-2. We first systematically analyze the dynamic changes of the optimal vigilance threshold with the succession inputs and propose a new adaptive method to make the network itself can automatically choose the optimal threshold in various situations. Then we introduce a constraint parameter to confine the scale of ART-2 network by limiting the maximal number of categories of network. Simulation experiments including artificial and benchmark data sets demonstrate the effectiveness of our algorithm.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130605068","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}

Taking equivalent circuit model parameters of Titania humidity sensor as optimizing object, an equivalent circuit optimization method is proposed based on improved genetic algorithm. Elitist strategy is added in select option of algorithm, and fitness function is suitably adjusted. Thereby, operational efficiency and accuracy of the algorithm are enhanced. Fitting curves and fitness function plots are obtained. The correctness of equivalent circuit is proved intuitionally by fitting curves. And the operating effects of algorithm are even more clearly expressed by fitness function plots. At the same time, the iterative method is used to compute parameter values of the equivalent circuit.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134043675","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 primary idea is to first build multivariate exponentially weighted moving average (MEWMA) model based on the originally measured variables to keep the memory effect of the process trend. Then introduce a unified Mahalanobis distance based monitoring statistic, which makes full use of the feature of the normal distribution of the process variables, to better capture the deviation of the process variables. A case study of the Tennessee Eastman process (TEP) is used to demonstrate the superiority of the proposed method over other conventional ones in performance and workload of the gradual small shifts monitoring.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129999984","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 process of forming penetrators is depicted in the test together with the process of penetration, which shows that under the same condition of diameter, the one with higher axis can form the rod-shaped penetrator with high velocity, large slenderness and rational mass distribution, but the effectiveness of caviting is much worse than the other two. Under the concrete model of Johnson-Holmquist-Concrete(JHC), the process of concrete board damage are analyzed, and we also obtained the data related to the depth and the cavity radius at the same time.

This bemuses workers, limits working efficiency, and may even lead to accidents. Additionally, prolonged exposure to such noise results in damage to the human hearing system. A better isolation of people from the noisy machines is frequently technologically unfeasible or very expensive. Communication headsets available on the market are not ergonomic. On the other hand, they are not accepted in warm and humid environments because wearing them may cause skin galls. Therefore, at some places in mines, power plants, car factories, assembly lines, etc., the workers use earplugs made from an elastic noise absorbing material, and communication between them is limited to a set of gestures only. The aim of the paper is to present NoiseCom — a complex ergonomic earplug-based communication-improvement solution, integrating high passive and active noise reduction, enhancement of speech intelligibility and wireless speech transmission for a group of workers. Developed algorithms are presented and obtained results are reported based on recordings in real industrial conditions.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125576650","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}

Signals from some distinguishing individuals aggregate through the network so that every agent could collect enough information about the true state. The observation from expert Bayesian agents will drive the average belief of the true state in the network convergence with possibility of 1 as time grows infinite. Instead of using a fully Bayesian manner, we choose a linear combination of some neighbor's Bayesian observation and the other's view directly. Under some mild assumption of existing at least an expert agent, the agent's beliefs of the underlying state of the world will increase by time, and the possibility of all agent's beliefs finally convergence to the underlying true state of the world become 1.","PeriodicalId":210380,"journal":{"name":"Proceedings of 2011 International Conference on Modelling, Identification and Control","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124201864","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}
