This hierarchical deployment of cells introduces the necessity of effective frequency planning for mitigation of interference between different layers of network. As the scarce spectrum resources are likely to be reused to increase spectral efficiency, interference free signal reception has to be guaranteed to ensure better quality of service (QoS). In this paper we propose a dynamic frequency reuse scheme for the deployment of femtocells within a macrocell with the femtocells reusing the spectrum of neighbouring macrocells. We also provide a protective scheme for cell edge femtocell users as they are vulnerable to interference signals from neighbouring macrocells. A detailed frequency planning is provided to maximize spectral reuse while providing maximum throughput. We compare our proposed scheme with other frequency allocation schemes already described in literature. Simulation results shows that our scheme provides better throughput and ensures lower outage probability.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125153396","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 presents a novel multi-step level set (LVS) method for segmenting cytoplasm and nuclei from overlapping cells in a single EDF image produced from Pap smear images of multi-layer cervical cell volumes. The first step segments the clump consisting of free or overlapping cells using a region-and edge-based level set method on the Gaussian filtered image. The second step segments the nuclei by a multi-step level set method from the original image. And finally, the most critical step of cytoplasm segmentation is done using level set method optimized by criteria such as curvature of the cytoplasm, duration of retaining the segmented area of the cytoplasm, edge information and a speed regulator depends on the homogeneity of the cell. The performance of the proposed algorithm is evaluated on the real cervical cell image provided by the second overlapping cervical cytology image segmentation challenge at ISBI 2015. Clump detection shows good result in spite of the weak clump boundary. Nuclei detection also shows good result in spite of congestion of nuclei. We are also able to segment two overlapping cells in the real Pap smear image.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"373 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407668","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}

First, the EEG epochs are decomposed into different real and imaginary coefficient bands and then, some statistical features like norm entropy and mean absolute deviation (MAD) have been calculated. These features are combined into a single feature space and after that optimal features have been selected automatically imposing some feature selection criteria from this combined feature space. The selected features have been justified as suitable to classify different kinds of motor imagery EEG signals by statistical hypothesis testing (e.g., one way ANOVA) and graphical analyses (e.g., scatter plots). Finally, K-nearest neighbor (kNN) based classifiers are developed using these selected features for classifying 2 types of imagery hand movements. 90.36% overall accuracy is achieved in publicly available BCI competition II Graz data set which is shown to be superior than several existing methods.","PeriodicalId":410572,"journal":{"name":"2015 IEEE International Conference on Telecommunications and Photonics (ICTP)","volume":"23 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113984641","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}
