In summer, the traditional two-ray model is expanded to three rays, where the new ray penetrates the top layer of ground until it is reflected by a change in the earth medium. In the winter, a five-ray model is used where snow covers the same ground. A genetic algorithm is used to determine the electrical characteristics of the ground and snow layers based on results from measurements taken from multiple positions and heights, in summer and winter. At a frequency of 2.35 GHz, the snow covering the ground during the winter campaign was found to have a relative permittivity of 11.3.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125750807","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}

Proposed design have stable frequency response up to 60 degrees of incidence angles. In the proposed hybrid design, three-armed geometry is placed in the center and two armed geometries are placed in each quadrant of the unit cell in order to reflect the incoming waves in 26.5 GHz frequency band. Two-legged geometries are placed in corners and square loop geometries are placed in each quadrant of the unit cell in order to reflect the incoming waves in 40 GHz frequency band. Analysis of the proposed surfaces are executed with Ansoft HFSS v.19 software. Simulation results show that proposed dual-band FSS reflects incoming electromagnetic waves between 25.5-27.3 GHz and 41.8-45.1 GHz frequencies. Achieved return losses are less than 0.55 dB in the desired frequency bands for the incident angles between 0° and 60° at both TE and TM polarizations. Proposed FSS can be used as a subreflector in multiband reflector antenna designs for satellite communication applications. Obtained results are also compared with similar works and discussed.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127643407","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}

With employing Time Slotted Channel Hopping (TSCH) mode, 6TiSCH can meet critical requirements in the industrial sector such as reliability, determinism and real time. 6TiSCH is currently focusing on monitoring applications. This paper considers its applicability in industrial control, in which sensor and actuator are coexistent in the network. We first investigate applicable wireless sensor-actuator models based on 6TiSCH. Then, an efficient data transmission scheme between sensor and actuator is proposed. Through simulation results, we show that our solution achieves a significant improvement in terms of end-to-end latency and energy consumption compared to the bursty transmission in the 6TiSCH networks.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134415547","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}

Vertical application areas like smart mobility, energy networks, industrial IoT applications, and AR/VR enhanced services all pose different requirements on the use of 5G networks. Some applications need low latency, whereas others need high bandwidth or security support. The goal of this paper is to identify the requirements and to understand the limitations for 5G driven applications. We review application areas and list the typical challenges and requirements posed on 5G networks. A main challenge will be to develop a network architecture being able to dynamically adapt to fluctuating traffic patterns and accommodating various technologies such as edge computing, blockchain based distributed ledger, software defined networking, and virtualization. To inspire future research, we reveal open problems and highlight the need for piloting with 5G applications, with tangible steps, to understand the configuration of 5G networks and the use of applications across multiple vertical industries.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126703747","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 is focused on coding the parameters of a hybrid genetic fuzzy system that is designed to use a genetic algorithm for optimizing the knowledge base of a previously created fuzzy system. The hybrid context-driven rule-based system (GFSSAM=Genetic Fuzzy Software System for Asset Management) is a real-time software system for supporting the decision process in managing investment assets. In the investment process stakeholders analyse, model, use raw data, and make decisions in which the perspective context plays a key role and so any software system in this area has to provide reliable context-aware results. GFSSAM is developed and tested on real-time data from the stock exchange in a project for extensive research on optimization of the inference machine and knowledge base of a fuzzy system through hybridization.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122386520","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}

Mathematical description of the observed surface is presented. A waveform with linear frequency modulation (LFM) reflected by the surface is used to produce a two-dimensional (2-D) SAR signal model presented as a sum of Hadamard products of two-and four-dimensional matrices (arrays) with a specially defined rectangular function. It is proven that the SAR signal formation and image reconstruction can be interpreted as direct and inverse projection operations. Based on linearization of the inverse projection, two-dimensional inverse Fourier transform is applied to obtain a complex image known as a Single Look Complex (SLC) image, which can be used for interferogram generation. To verify the proposed SAR kinematics and geometry, surface geometry, signal models and image reconstruction algorithms a numerical experiment is carried out.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"27 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133683506","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 a previous paper, we have proposed a top-down approach for modeling context-aware vehicle navigation systems. We have also proposed an innovation concerning the technical aspects of navigation. Furthering this work, we discuss in the current paper more thoroughly the issue of GPS shadows identification and our proposed ways of overcoming them. It is important to mention that overcoming GPS shadows is considered complementary with regard to a typical GPS navigation. We therefore assume a context-aware service provisioning where an \"A Scenario\" GPS navigation gives way to an alternative \"B Scenario\" navigation in the event of encountering GPS shadows. We especially focus on the latter, by super-imposing GPS shadows calculation and corresponding real-time measurements, for the sake of precision. Counting on those two \"channels\" is expected to provide an adequate \"B Scenario\" alternative to the typical GPS navigation when obstacled by GPS shadows.","PeriodicalId":409637,"journal":{"name":"Proceedings of the Seventh International Conference on Telecommunications and Remote Sensing","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131440033","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}
