Due to its fast maximum-likelihood(ML) decoding, STBC is commonly used in MIMO system. However, most of the existing STBC methods rely on the availability of accurate channel state information (CSI) at the receiver. Furthermore, the complexity of the ML algorithm grows exponentially with the number of transmit antennas and constellation size. Especially when the number of transmit antenna is more than two, in order to enhance the symbol transmission rate, its complexity increases greatly. Therefore, intelligent receiver based on RBF neural networks is designed for 3 transmit antennas and 4 receive antennas MIMO system, in which a PCA approach is applied to process the train samples and online sequential extreme learning machine (OS-ELM) is adopted to adjust the parameters of the of RBF neural network. Compared with ML decoder, the proposed receiver has a high precision and good performance to track the variations of the fading channels. The result of simulation illustrates the effectiveness and feasibility of the receiver introduced.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115533536","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}

These web services can be selected statically during design-time or dynamically during run-time. The functional and non-functional QoS requirements are typically captured in the Service Level Agreement (SLA) that is mutually agreed between the service provider and the service consumer. Whenever an SLA violation happens, the service provider incurs a penalty. In order to minimize such penalties, the application that is built through a design-time composition of web services needs to be monitored. Whenever a violation of SLA is predicted, those statically composed web services are dynamically reconfigured. This is called as dynamic reconfiguration in SOA. In this case, even the alternate service selection happens at design-time itself. On the other hand, whenever the web services needed for an SOA application development are selected and composed dynamically at run-time, it is called as dynamic composition. The turnaround time involved in both these approaches for mission-critical applications with stringent SLA requirements is compared. It has been inferred that the dynamic reconfiguration approach not only maintained the turnaround time always within the accepted limits, it also incurred only less overhead when compared to dynamic composition approach.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126895305","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}

Detection of diabetic retinopathy (DR), Glaucoma and Edema are the ones in which OD detection finds the meaning and need. The method proposed here introduces a unique concept of fractal analysis in its own way, exploiting the geometric structure of eye called Pixel Based Multi Fractal Analysis (PBMFA). At the very outset the retinal fundus images are pre-processed employing a modified Contrast Limit Adaptive Histogram Equalization (CLAHE) method. Furthering Mean Based Localization is carried out on the pre-processed image to locate the Region of Interest (ROI) over which further processes are carried out helping in improvising time complexity and efficiency of the algorithm developed. Modified Canny Edge detection leveraged with Gabor operator is performed over the ROI located, resulting in extraction of blood vessels from the retinal image. Pixel Based Multi Fractal Analysis is done locating the origin of vascular tree (center of the OD), based on the fact that it carries highest fractal dimension. This helps us locate the center most accurately followed by which OD of the retinal image is traced. This algorithm was implemented on DSK6713T making it a real time system and also an end product ready. Hardware implementation results in improvisation of the time complexity of the system too. An evaluation of the proposed algorithm was run over a set of 50 images each from STARE, MESSIDOR and DRIVE projects, containing images from both normal and pathological subjects. Detection and tracing of Optic Disc was found to be accurate up to 98.66%. Abnormal cases like expansion OD in the final stage of diabetic retinopathy were also detected successfully.","PeriodicalId":269595,"journal":{"name":"2017 International Conference on Computer, Communication and Signal Processing (ICCCSP)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126453728","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}
