FTTH involves the installation of optical fiber network from a central service provider to individual users. An innovative technology for FTTH implementation is Passive Optical Network (PON), which provides unprecedented bandwidth. The attributes of modern passive optical network (PON) such as high reliability, low cost, passive functionality are mainly responsible for the proliferation of optical fiber access. The recent trends in fiber access passive optical networks include Ethernet Passive Optical Network (EPON), Gigabit Passive Optical Network (GPON) and Wavelength Division Multiplexing Passive Optical Network (WDM PON). This paper focuses on PON such as GPON and next generation WDM PON. This paper discusses key technological aspects, and challenges of GPON, and next generation WDM PON and aims to provide insights to a reader by doing a comparative study of the two fiber access passive networks on the basis of cost, capacity and flexibility.","PeriodicalId":422275,"journal":{"name":"2014 International Conference on Recent Trends in Information Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122344247","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}

All clustering techniques have some assumptions on the underlying dataset. We can get accurate clusters if the assumptions hold good. But it is difficult to satisfy all assumptions. Currently, not a single clustering algorithm is available to find all types of cluster shapes and structures. Therefore, an ensemble clustering algorithm is proposed in this paper in order to produce accurate clusters. Moreover, the existing clustering ensemble methods require more number of clusters in advance to produce final clusters. In this paper, we propose a novel method which groups a set of clusters into accurate final clusters to enhance the decision accuracy. This method does not need the number of clusters as input but produces the clusters automatically assuming the no of clusters.","PeriodicalId":422275,"journal":{"name":"2014 International Conference on Recent Trends in Information Technology","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121120703","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 novel technique using Bayesian Network Model Based (BNMB) Image Segmentation, which is a probabilistic graphical model for segmentation of lung tissues from the X-ray Computed Tomography (CT) images of chest, is proposed. Goal of this work is to present an automated approach to segmentation of lung parenchyma from the rest of chest CT image. This is implemented with help of a probabilistic graph construction from an over-segmentation of the image to represent the relations between the super pixel regions and edge segments. Using an iterative procedure based on the probabilistic model, we identify regions and then these regions are merged. The BNMB is evaluated on many CT image databases and the result shows higher accuracy and efficiency for both segmenting the CT image of lung and also extraction of the Region Of Interest (ROI) from affected CT image.","PeriodicalId":422275,"journal":{"name":"2014 International Conference on Recent Trends in Information Technology","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116292855","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 principle components and local space variations are extracted and represented in the form of Eigen vectors. Matching of a knuckle images for personal identification is done by means of a classifier using correlation. Matching scores obtained from various finger knuckles of the same person are fused by means of sum-weighting rule of matching score level fusion. From the exhaustive experiments conducted using two publically available database for FKP, viz.

Traditional architectures for cognitive radio networks (CRNs), such as cognitive cellular networks and cognitive ad hoc networks, impose energy-consuming cognitive radios to SUs' devices for communication and cannot efficiently utilize the spectrum harvested from the primary users (PUs). To enhance the spectrum and energy efficiencies of CRNs, we have designed a new architecture, which is called the Cognitive Capacity Harvesting network (CCH). In CCH, a collection of relay stations (RSs) with cognitive capability are deployed to facilitate the accessing of SUs. In this way, the architecture not only removes the requirement of cognitive radios from SUs and reduces their energy consumption, but also increases frequency reuse and enhances spectrum efficiency. In view of the importance of the RSs on the improvement of spectrum and energy efficiencies, in this paper, we study the RS placement strategy in CCH. We design a framework of heuristic algorithms to compute the near-optimal solutions. The simulation result show that the proposed algorithms outperform the random placement strategy and is always within 2 times of that in the optimal solution.","PeriodicalId":422275,"journal":{"name":"2014 International Conference on Recent Trends in Information Technology","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122060698","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}

In this paper, data from social tagging systems are extracted for every individual considering the correlations between users, items, and tag information. Tag information from users is the most decisive factor to predict the personalized suggestion for web users. Here, we rank the available content based tag information with the inclusion of temporal decay of users' behavior over time and the centrality of every node in the network.

Three planes of the noisy image are denoised separately through Legendre Fenchel Transformation. Later, these three planes are concatenated and compared with results obtained by Euler-Lagrange ROF model. Simulation results show that Legendre Fenchel ROF is highly convergent and less time consuming. To add evidence to the outcomes, quality metrics such as variance and PSNR for noisy and denoised images are calculated.
