This deployment strategy has however, resulted in the need for high capacity, low cost backhaul systems. Millimeter-wave (mmW) technologies with inherent Gbps capacity are currently being considered as possible solutions. However, like all wireless systems deployed in urban, mmW backhaul solutions will require clear line-of-sight for proper operation. The systems must also have autonomous capabilities to achieve the scalability and flexibility expected of 5G transport systems. Recent measurement campaigns have shown that usable links based on diffracted signals are achievable under non-line-of-sight (NLOS) conditions in urban environments. In our earlier work, an intelligent NLOS SCB system which uses diffracted signals has been proposed. In this paper we study existing propagation models for urban environments. We use the Single Knife Edge Diffraction (SKED) model to predict diffraction loss on the propagation path due to knife edge obstructions for street level to roof top NLOS SCB links. Using ideal SKED parameter values to be used in the design and optimization of typical NLOS SCB systems, a numerical analysis of the effect of varying these parameters on diffraction loss is carried out. The results obtained show that the model can be used in the development of algorithms for SCB radio devices with cognitive and self-organizing capabilities. Future work will involve the development of such algorithms using Genetic Algorithm.","PeriodicalId":133824,"journal":{"name":"IEEE EUROCON 2015 - International Conference on Computer as a Tool (EUROCON)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115148257","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}

Although it cannot be cured, its progression may be prevented if it is early detected. Expert ophthalmologists use as a sign of suffering from the disease, the evaluation of the relationship between optic disc and cup areas in retinal fundus images and, therefore, image processing techniques applied to glaucoma has become an emerging research line. This paper presents a novel technique for the detection of the optic cup in retinal fundus images, which may be included in a glaucoma computer aided diagnosis tool. The method, based on a color space related to human perception and adapted to surrounding conditions, JCh from CIECAM 02 (International Commission on Illumination Color Appearance Model), utilizes a random forest classifier to obtain cup edge pixels. As vessels tend to bend in the edge of the cup, the classifier does not consider all the pixels in the image. In fact, only those belonging to vessels and possessing the highest curvature among their neighbors are taken into account. Another prior knowledge used in the proposed method is the fact that cup area usually posses a bright yellow color. Therefore the feature vector serving as an input for the classifier is made with the curvature, the color of the candidate pixel and its location relative to the OD center. Finally, a basic post processing is performed to join the selected pixels with a smooth curve. The method has been tested in a publicly available database, GlaucomaRepo, from where we used 35 images for training and 55 for test. Five numerical parameters were calculated and a comparison against three color spaces was performed. The results obtained indicate the effectiveness of the approach.","PeriodicalId":133824,"journal":{"name":"IEEE EUROCON 2015 - International Conference on Computer as a Tool (EUROCON)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116776760","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}

As femtocells are user-installed devices, subscribers will be more interested in acquiring them. Nonetheless, femtocells come with their challenges and one of the main problem associated with femtocells is interference. Interference can occur between macrocells and femtocells (cross-tier) or amidst femtocells (co-tier). This paper proposes a power control scheme which attempts at mitigating both co-tier and cross-tier interference. The benefit of this scheme is the significant reduction in the femtocell transmit power particularly at low traffic load. In contrast, to previous power control schemes, 100% and 76% decrease in the transmitting power of the femtocell is noted at low traffic loads for the user located furthest away from the access point, when the access point is positioned at the center and near the house edge of the ground floor respectively. Besides, 95% reduction in signal leakage out of the house is observed considering highest channel bandwidth compared to previous power control schemes when the access point is positioned in the middle of the house.","PeriodicalId":133824,"journal":{"name":"IEEE EUROCON 2015 - International Conference on Computer as a Tool (EUROCON)","volume":"342 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122759922","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}
