This paper presents a coarse grained hierarchical time synchronization scheme `LevelSync' which synchronizes nodes in a sensor network with regards to their distance from the sink or master node. A hierarchical tree is dynamically constructed during the synchronization with master node acting as the root. The master node initiates and controls the synchronization phase and is responsible for normalizing the virtual time with the corresponding UTC. Each node is assigned a level and maintains a virtual clock which runs at a frequency different than that of its physical clock. Virtual clocks run at a fixed frequency calculated by the root or reference nodes hence are free from the drifts. LevelSync decreases the number of messages required for the synchronization and the resynchronization periods. We evaluate the performance and energy efficiency of the LevelSync through simulation and compare with existing time synchronization protocols. LevelSync is computationally light, energy efficient and achieves long lasting synchronizations.","PeriodicalId":444918,"journal":{"name":"2014 Seventh International Conference on Contemporary Computing (IC3)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116231445","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}

This paper proposes a novel way of arriving at a consensus clustering by an ensemble selection strategy. The method avoids considering the entire ensemble and judiciously select few clusterings in the ensemble without compromising on the quality of the consensus. It begins with sorting the ensemble by prioritizing clusterings based on diversity and frequency. It is observed that considering jointly the diversity and frequency helps in identifying few representative partitions that have high potentiality to form qualitatively better consensus than that of the entire ensemble. Finally a greedy strategy is used to select the clusterings in an iterative consensus generation technique that ensures the internal quality of clustering to be monotonically non-decreasing. Empirical results show that the consensus clustering obtained by the proposed algorithm gives better clustering accuracy for many datasets.","PeriodicalId":444918,"journal":{"name":"2014 Seventh International Conference on Contemporary Computing (IC3)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132412394","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}

Paper mainly describes all the features extraction mechanism for the SOM input and we devised an algorithm for creating the clusters of the raga based on their PCP (pitch class profiles) and the onsets detected. Our strategy is very promising that its providing better clusters of the raga patterns and the raga segments are very much clearly be distinguished from the other ragas, as we compared them with the formation of the key attributes. The Indian classical music history is very old and the need for identifying the music based on the raga onsets is very much helping for the music professionals and domestic users for identifying and detecting the raga types and using the same without the help or availability of any experts nearby. Thus our strategy is very promising in nature for the novice users and practitioners as well as home users. The very early learners would also find it very interesting and supportive after due course of frequent uses of it. At last we provided the future possibilities for the enhancements.","PeriodicalId":444918,"journal":{"name":"2014 Seventh International Conference on Contemporary Computing (IC3)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115128374","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}

High-resolution remote sensing satellite images contain more information in the discrete samples and after resampling process, it is desirable that the reconstructed image should maintain the same sharpness as the original image. Although several techniques are available, but it is essential to determine the best one for maintaining the sharpness and the pixel break at higher magnification level for photographic and digital display of high resolution satellite images. To preserve image quality, the interpolating function used for the resampling should be an ideal low-pass filter. In order to determine the best interpolation function, different resampling functions, namely Nearest Neighbor (NN), Bilinear (BL), Cubic Convolution ( α = 0 ), High-resolution Cubic Spline with Edge Enhancement ( α = -1 ), High-resolution Cubic Spline ( α = -0.5 ), Cubic Spline ( α = -2 ), Cubic Spline ( α = -.3/4), Cubic B-spline, Catmull-Rom Cubic, Quadratic Interpolation and Approximating Quadratic B-Spline have been analyzed on different spatial resolution Indian Remote Sensing (IRS) satellite images (LISS-III, LISS-IV and CARTOSAT-1). Performance of the above resampling methods has been evaluated by Visual interpretation, Digital Number Percentage (DN %) Analysis as well as other parameters likes Entropy and Image Noise Index (INI), MSE and PSNR. Investigation results have shown that with the change in the image processing operation, spatial resolution and evaluation parameter, the performance of resampling method changes, thereby emphasizing the need to judiciously select the resampling method.","PeriodicalId":444918,"journal":{"name":"2014 Seventh International Conference on Contemporary Computing (IC3)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125190813","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}
