In developing countries, testing for detection of this cancer involves visual microscopic test of cytology samples such as Fine Needle Aspiration Cytology (FNAC) taken from the patient's breast. The result of analysis on this sample by Cyto-pathologist is crucial for breast cancer patient. The wavelet transform has become an important tool for many biomedical image and signal application, which at the detection and analysis of image features. In this paper, clusters of nucleus in the sub-band images of FNAC samples is investigated after decomposition by means of the Complex Discrete Wavelet Transform (CDWT) and a new method is developed to compute the variability and other nucleus statistical textural features. The experimental data are taken from FNAC samples of benign and malignant cases. The calculated variance parameters and texture features permit the characterization of nucleus clusters variable and distinguish malignant samples from benign in cytological breast fine needle aspirate images.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121644414","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}

With increase in number of components integrated to single System-on-Chip (SoC), there is corresponding increase in communication between them. This makes on-chip bus based communication a major challenge in current SoC technology. A segmented bus architecture shows potential for improving both speed and power related features of a bus-based system. Due to segmentation of the bus, parallel transactions can take place, thus increasing the performance of the bus. In order to reduce arbitration and communication delay in the existing segmented bus, new reconfigurable architectures which will completely avoid the complicated higher level arbitration over-head with a small modification in local arbiter is proposed in this paper. The bus architectures are modeled using VHDL and simulated using Xilinx ISE 9.2i. The simulation results show that the proposed architecture performs better than the existing segmented bus, in terms of operating frequency, communication delay and bandwidth. Hence the proposed architecture can be used for high speed real-time applications.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131490590","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}

A simulation study has been carried out to evaluate performance of such WSN employing space diversity in terms of optimal transmit power. Optimal transmit power is the minimum power required to sustain the network connectivity while maintaining a predefined maximum tolerable Bit Error Rate (BER) in WSN. Optimization of transmit power is of great importance in WSN since sensor nodes are battery driven and optimization helps to increase battery life by reducing inter node interference significantly. The impact of Maximal Ratio Combining (MRC) based space diversity on optimal transmit power is investigated in presence of Rayleigh fading. Use of MRC space diversity in Rayleigh fading channel shows a significant reduction in optimal common transmit power. Average number of retransmissions for successful delivery of a packet is also evaluated considering an infinite Automatic Repeat Request (ARQ) scheme.","PeriodicalId":106953,"journal":{"name":"2010 5th International Conference on Industrial and Information Systems","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131852940","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 governing delay-differential equations of dynamic systems are converted into linear algebraic equations by using the operational matrices of integration, delay and product of BPFs. Thus, the problem of finding optimal control law is reduced to the problem of solving algebraic equations obtained via the operational matrices.
