However MIMO OFDM suffers from high PAPR, this demands expensive linear amplifiers with wide dynamic range. In MIMO OFDM systems, a straightforward way for PAPR reduction is to apply existing techniques separately on each transmit antenna, then the overall PAPR reduction is obtained. A proposed technique based on modified partial transmit sequences (PTS) using circular shifting and phase rotation is employed to achieve more reduction in the overall PAPR in MIMO OFDM, it exploits the extra degree of freedom provided by MIMO to reduce the overall PAPR. Two sub-optimal solutions for modified PTS are suggested, to reduce the complexity and side information in MIMO OFDM, with slight loss of PAPR reduction performance.","PeriodicalId":256564,"journal":{"name":"2013 9th International Computer Engineering Conference (ICENCO)","volume":"56 6 Suppl 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132030141","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}

Not only can stack store items at the top, but also can store items at the bottom, side(s), as outer ring, inner ring or randomly. The purpose of this paper is to develop the mathematical foundations and their programming algorithms for the necessary handling of the insertion and deletion operations in each of six generalized stacks. A Generalized Data Stacking Programming (GDSP) model is proposed to simulate what happen in the real world. GDSP uses the growing/shrinking matrix based implementation which is a generalization of the known array representation to be another way of implementing the stack.","PeriodicalId":256564,"journal":{"name":"2013 9th International Computer Engineering Conference (ICENCO)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133744234","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}

Firstly, preprocessing phase which converts CT image into binary image using adaptive threshold method that examine the intensity values of the local neighborhood of each pixel. Then, the second phase is to apply multi-scale morphological operators to filter tissues nearby liver and to preserve the liver structure and remove the fragments of other organs. The third phase is a post-processing that uses connected component labeling algorithm (CCL) to remove small objects and false positive regions. The algorithm is tested using two different datasets and the experimental results obtained, show that the proposed approach are promising which could segment liver from abdominal CT in less than 0.6 s/slice and the overall accuracy obtained by the proposed approach is 93%.","PeriodicalId":256564,"journal":{"name":"2013 9th International Computer Engineering Conference (ICENCO)","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134090685","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 high frequency components of the combined image and the image source are correlated. The result of correlation is used in classifying the pixel whether belongs to image source or zero. The experiment is applied on the other image source and the combined image.

These features are used for automatic eye screening systems that provide an accurate and efficient tool for the early detection of many eye diseases. A method for detecting these features is presented in this paper. First, the blood vessels are detected by using the mathematical morphology. Then, based on the percentage of the brightest pixels in the OD, the temporal side is detected since it contains the brightest region in the OD. By combining the information from temporal side and blood vessels, the whole OD is segmented. Finally, the macula is extracted by using the spatial relationship with the OD. The proposed method is tested on two publicly databases DRIVE and DIARETDB1. The detection of the OD achieved a success rate of 97.5% and 95.5% for DRIVE and DIARETDB1 respectively while the macula is detected correctly with a success rate of 100% and 97.6% respectively.","PeriodicalId":256564,"journal":{"name":"2013 9th International Computer Engineering Conference (ICENCO)","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130483579","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}
