Unfortunately, the far field beam pattern in ultrasound is a sinc function, which has a better main lobe (the resolution of ultrasound imaging) and high side-lobe about -13dB down from the maximum on axis value (the contrast of ultrasound imaging). The result for that is one of a famous artifact in medical ultrasound that the anatomy of the organ outside the main beam to be mapped into the main beam. In this work we used different types of FIR filter to round edges of the aperture that taper towards zero at the ends of the aperture to create low side-lobe levels and reduce the false echo. We used the windowing function (Blackman, Kaiser (β=10), Parzen and Bohman) as apodization function to the reconstructed image to reduce the effect of the side-lobes. We computed the SNR for each image as well as for the main lobe and the side-lobe. The results showed that there is trade-off in selecting these functions: the main lobe of the beam broadens as the side-lobes lower. However, Kaiser (β =10) gave the best SNR (188.75 db) and best compensation between the contrast and resolution (main lobe=1.10 db and the side-lobe= -71.7 db). We found that if we use the Kaiser filter (β =10) this would reduce the side-lobe and improve the false echo in the ultrasound imaging.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"344 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120883174","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 proposed Design which includes a programmable DDS, mixer and three cascaded stages of programmable digital filters has been simulated with Matlab, designed with Xilinx system generator and synthesized with Xilinx Synthesis Tool (XST) targeting Spartan 3A based xc3sd1800a FPGA. The Dual-mode feature is achieved by using a control unit which loads the filters coefficients of each system from ROM to the programmable digital filters upon desired System. The programmable DDS module is generated by Xilinx DDS Compiler and can operate at maximum frequency of 61.44MHz and provide the flexibility for multi-carrier base station. The results show that the system design flow based on Xilinx System Generator is simple and feasible and meets the performance requirements for the downlink transmit path for each system. The proposed design is consuming very less resources available on target device to provide cost effective solution for SDR based wireless applications.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130656027","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}

Credit scoring models have been applied by many researchers to improve the process of assessing credit worthiness by differentiating between prospective loans on the basis of the likelihood of repayment. Thus, credit scoring is a very typical Data Mining (DM) classification problem. Many traditional statistical and modern computational intelligence techniques have been presented in the literature to tackle this problem. The main objective of this paper is to describe an experiment of building suitable Credit Scoring Models (CSMs) for the Sudanese banks. Two commonly discussed data mining classification techniques are chosen in this paper namely: Decision Tree (DT) and Artificial Neural Networks (ANN). In addition Genetic Algorithms (GA) and Principal Component Analysis (PCA) are also applied as feature selection techniques. In addition to a Sudanese credit dataset, German credit dataset is also used to evaluate these techniques. The results reveal that ANN models outperform DT models in most cases. Using GA as a feature selection is more effective than PCA technique. The highest accuracy of German data set (80.67%) and Sudanese credit scoring models (69.74%) are achieved by a hybrid GA-ANN model. Although DT and its hybrid models (PCA-DT, GA-DT) are outperformed by ANN and its hybrid models (PCA-ANN, GA-ANN) in most cases, they produced interpretable loan granting decisions.","PeriodicalId":256793,"journal":{"name":"2013 INTERNATIONAL CONFERENCE ON COMPUTING, ELECTRICAL AND ELECTRONIC ENGINEERING (ICCEEE)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132121088","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}
