Computational remodeling has been well established in lone bone community and a range of mathematical formulae have been available with acceptable accuracy and effectiveness. However, there has been limited information and remodeling data available for dental scenarios, despite its predominate importance and popularity in clinic. An in-vivo frequency test technique was developed to determine the extent of osseointegration and remodeling passively. It could not help predict on-going healing and consequence of implantation. This paper develops a predictive model to relate osseointegration and bone remodeling to a progressive change in natural frequencies, thereby better utilizing the data acquired from experiments. The results allow us to establish a more realistic remodeling formula, thereby making a patient-specific prediction possible.","PeriodicalId":178669,"journal":{"name":"2009 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133948473","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 particular, we show that under some conditions, that we introduce and present in this paper, related to the interconnected links time-delays, the less connected a given dynamical system is, the longer it will take for the overall system to stabilize. We address the conditions for obtaining an estimate of the convergence time of the system based on the system interconnections weights and time delays. In particular, we study the conditions under which such property is conserved when homogenous and/or heterogeneous time delays are introduced to the links of the interconnected system considered. Analysis of the affect of arbitrary heterogeneous time delays on the dynamical system links, system stability, and convergence time is also presented.","PeriodicalId":178669,"journal":{"name":"2009 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134445312","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}

This paper aims to construct a three-dimensional finite element (FE) model to examine the current flow path in different surrounding tissues involved. The MRI data is processed to generate solid model and then FE model for the numerical analysis, which contains gray and white matters of the brain that was assembled and was analyzed in ABAQUS.

In the AWF, the optimization of the normalized weights is obtained with the constrained quadratic programming. Depending on the prediction errors of the CNNs from one input sample to another, the AWF can adaptively adjust the weights which are assigned to the CNNs. The results of the function approximation experiments on six benchmark data sets demonstrate that the AWF method can effectively help the multi-learner system achieve higher accuracy (measured in terms of mean-squared error) of prediction, in comparison with the popular the Bagging algorithm.","PeriodicalId":178669,"journal":{"name":"2009 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127073953","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}

By collecting, analysing and preprocessing some of the data available in the system it is possible to recognize and/or predict error situations arising in the system. This can be done without detailed knowledge of the system, nor of the data available. Hence the presented methods could be used in similar system without significant changes. The TDAQ system, and in particular the main components related to this work, is described together with the test setup used. We simulate a number of error situations in the system and simultaneously gather both performance measures and error messages from the system. The data are then preprocessed and neural networks and support vector machines are applied to try to detect the error situations, achieving classification accuracy ranging from 88% to 100% for the neural networks and 90.8% to a 100% for the support vector machines approach.","PeriodicalId":178669,"journal":{"name":"2009 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications","volume":"21 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129577322","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 this paper, we present a novel method for accelerating the setting of Q-values in the well-known Q-learning algorithm. Fuzzy rules indicating the state values will be used, and the knowledge will be transformed to the Q-table or Q-function in some first training experiences. There have already been methods to initialize the Q-values using fuzzy rules, but the rules were the kind of state-action rules and needed the expert to know about environment transitions on actions. In the method introduced in this paper, the expert should only apply some rules to estimate the state value while no appreciations about state transitions are required. The introduced method has been examined in a multiagent system which has the shepherding scenario. The obtaining results show that Q-learning requires much less iterations for getting good results if using the fuzzy rules estimating the state value.","PeriodicalId":178669,"journal":{"name":"2009 IEEE International Conference on Computational Intelligence for Measurement Systems and Applications","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129246653","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}
