The sensors are installed on the critical power grid equipments to acquire the essential grid datas such as voltage, current and system frequency. And the data acquisition in smart grids is particularly time sensitive: the accurate timestamp of information is required from the sensors so that the absolute time of acquisition can be determined. Due to the crystal manufacturing tolerance and working conditions, the clocks of sensor nodes oscillators are non-identical and drifting. Thus, the key enabling technology time synchronization, aiming to provide a common sense of timing, is required in distributed smart grids sensor networks. Inspired by Peskin's model for self-synchronization of cardiac pacemaker, the pulse-coupled oscillators is implemented to the wireless sensor nodes to ensure the wireless networks of smart grids be able to achieve a common timescale, it is also suitable for distributed deployment in large-scale smart grids. In addition, the intensive simulations of three kinds of single-hop wireless sensor networks have been carried out to evaluate the performance of linear pulse-coupled non-identical oscillators.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128698343","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 dual-polarization (VV+VH) Interferometric Wide (IW) swath mode image acquired on February 10th 2018 along descending orbit over Hyderabad city, India has been used. Data have been calibrated, terrain corrected, and filtered by a kernel using gamma filter method. For terrain correction a 30m resolution Shuttle Radar Topography Mission Digital Elevation Model (SRTM DEM) has been used. Radar data has been reduced to a spatial resolution of 20m. In general SAR images are well suited to detect urban areas thank to the strong signal responses by double-bounce scattering at the dihedral corner reflector between the ground and the building wall. Different combinations of VV and VH polarizations have been analyzed and the resulting classified images have been evaluated to assess the total classification accuracy. At the end it has been demonstrated that, combining dual-polarization Sentinal-1 data are suitable for producing accurate land cover maps in urban areas for metropolitan cities management purposes. This could represent a significant advantage in the case of regions frequently affected by clouds.","PeriodicalId":447143,"journal":{"name":"2018 5th International Symposium on Environment-Friendly Energies and Applications (EFEA)","volume":"80 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127422746","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}
