The paper describes a mechanical model ruling bearing devices' defects. The proposed model concerns defects related to surface waviness, flaking defects as well as those due to unbalanced rotor's effects. The defects' detection is formulated in the frame of vibratory analysis.","PeriodicalId":350490,"journal":{"name":"6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134368678","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}

Yong, Wang Rui","doi":"10.1109/CISIM.2007.18","DOIUrl":"https://doi.org/10.1109/CISIM.2007.18","url":null,"abstract":"A multi-frequency lossless watermarking algorithm is proposed in this paper. Bandelet and optimal matrix norms are used to draw the geometric feature and the statistic feature. The bandelet transform is applied to the image, and the texture and edge traced by using the geometric flow via feature of the image to build the high frequency lossless watermarking. A low frequency watermarking scheme is also achieved, by selecting optimal matrix norm to process the low frequency part of wavelets coefficients. The experiments show the offered watermarking system is evaluated against standard watermarking attacks.","PeriodicalId":350490,"journal":{"name":"6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126044733","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}

Semi-Automatic Segmentation of Fibrous Liver Tissue 肝纤维组织的半自动分割

{"title":"Semi-Automatic Segmentation of Fibrous Liver Tissue","authors":"P. Andruszkiewicz, C. Boldak, J. Jaroszewicz","doi":"10.1109/CISIM.2007.57","DOIUrl":"https://doi.org/10.1109/CISIM.2007.57","url":null,"abstract":"This article presents a semi-automatic segmentation of the fibrous liver tissue in the in-vivo liver biopsy color images. The segmentation is performed using a tree-based classifier, with decision rules as tree leaves and binary operators (AND, OR) as tree nodes. Several image's local characteristics have been exploited, based on the image points' intensity levels, as well as taken from the texture analysis domain (fractal dimension, FFT, Gabor filters). Their effectiveness concerning quality of extraction has been compared using real clinical images with a manual delimitation given by physicians, as a reference. A user friendly application has been developed which enables the operator to interactively create and store the classifiers. It also offers to a physician a predefined set of the best found classifiers, to allow him an effective work in his every-day practice. The method is semi-automatic - it still leaves to the operator, beside the classifier choice, a possibility to manually (with the mouse) adjust the main parameter (s) which visually, on the fly, grows/shrinks the extracted fibrous region.","PeriodicalId":350490,"journal":{"name":"6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122049087","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 paper presents a dimensionality reduction algorithm based on informed feature selection. Terms describing the document are based on histogram-like statistics which can be computed as well as incrementally updated at low complexity. The document representation can adapt to changing document collection characteristics. Along with the fundamental concepts we present an empirical verification of the approach.","PeriodicalId":350490,"journal":{"name":"6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127831379","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}

ORRP: Optimal Reactive Routing Protocol for Mobile Ad-Hoc Networks ORRP:移动Ad-Hoc网络的最佳响应路由协议
N. Chaki, R. Chaki
{"title":"ORRP: Optimal Reactive Routing Protocol for Mobile Ad-Hoc Networks","authors":"N. Chaki, R. Chaki","doi":"10.1109/CISIM.2007.55","DOIUrl":"https://doi.org/10.1109/CISIM.2007.55","url":null,"abstract":"An ad-hoc network is a self-supporting collection of mobile nodes that happen to exist within a close proximity in an interval of time. In this paper, a reactive routing protocol has been proposed that computes the shortest path in between any source-destination pair on demand. The approach, unlike other reactive protocols, finds a loop-free, optimal path between the end nodes. It does not use broadcasting like DSR or some other reactive protocols. In fact ORRP exchanges only (n-1) control packets, in the best case. A comparative performance evaluation establishes the advantages of ORRP. The paper is a substantial extension of our earlier work reported in [S. Dulta et al., 2006].","PeriodicalId":350490,"journal":{"name":"6th International Conference on Computer Information Systems and Industrial Management Applications (CISIM'07)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127146062","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}
