Hence it is no longer necessary to convert inequality constraints into equality constraints by slack variables in order to reuse those results concerned only with equality constraints. Utilizing this technique, improved Lagrange nonlinear programming neural networks are devised, which handle inequality constraints directly without adding slack variables. Then the local stability of the proposed Lagrange neural networks is analyzed rigorously with Lyapunov's first approximation principle, and its convergence is discussed deeply with LaSalle's invariance principle. Finally, an illustrative example shows that the proposed neural networks can effectively solve the nonlinear programming problems","PeriodicalId":116729,"journal":{"name":"Sixth International Conference on Intelligent Systems Design and Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126372077","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}

Characterizing the pulmonary nodules in the multislice X-ray computed tomography (CT) images is notoriously difficult. This is due to the fact that the anatomical structures such as blood vessels, bronchi, and alveoli are subject to partial volume effects. Furthermore, the nodules connected with other dense anatomical structures increases the detection difficulties. In this paper, we propose a multiscale enhancement filter to improve the sensitivity for nodule detection, which is based on the undecimated wavelet transform and the eigenvalues of Yu matrix in multiplanar slices. As a preprocessing step of CAD for nodule detection, our enhancement filter can simultaneously enhance blob-like objects and suppress line-like structures. Therefore, it would be useful for reducing the number of false positives. We applied our enhancement filter to synthesized images and real medical images to demonstrate that it works well on enhancing a specific shape and suppressing other shapes. Our approach proposed in this paper is generic and can be applied for the analysis of blob-like structures in various other applications","PeriodicalId":116729,"journal":{"name":"Sixth International Conference on Intelligent Systems Design and Applications","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127404485","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 method shows how to recognize words without segmentation. The top and bottom views of the word are analyzed in order to create the feature vector.

And then, the reduced information table is used to develop classification rules and train SVM. The rationality of hybrid system is using rules developed by rough sets and SVM.

The interconnections are assumed to be bounded by a linear function of delayed states with unknown gains.

The adaptation laws are proposed to estimate such unknown bounds, and by making use of the LMI method, a class of decentralized robust adaptive controllers is constructed. Based on the Lyapunov stability theory and Lyapunov-Krasovskii functional, it is shown that the state trajectories of the large-scale systems are uniformly asymptotically to zero.
