PV cells have seen great efficiency improvements in the past years, furthermore according to Swanson's law PV cells become more and more affordable, but a lot of obstacles in effective utilization are still present. Energy harvesting systems with solar tracker can obtain significant improvement in solar energy exposure in comparison with static systems. The aim of this paper is to investigate the efficiency improvement given by a dual axis automated solar tracker and the maintenance and evaluation benefits of a real-time monitoring system.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127763826","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}

However, compression and transmission processes introduce visible artifacts in video signal. Thus video quality needs to be monitored and evaluated continuously. In this work a new solution that enables the additional offline analysis of detected video artifacts is proposed. The solution is based on Real-time Audio and Video Artifacts Detection Tool (AVADT) and it displays the timeline accompanied by the markers of different artifacts in different moments of video stream. Furthermore, in the proposed solution the reproduction of video segments that contain detected artifacts is enabled. By using the proposed solution, video service providers can perform the extended analysis and check existing trends related to artifact occurrence during video streaming.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132449244","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}

Cooperating nodes communicate applying either a threshold-based or an Automatic Repeat reQuest (ARQ) protocol. Closed-form analytical expressions are derived when the network destination node applies maximal ratio combining, and are further verified through Monte Carlo simulations. The effects of type of protocol used, average signal-to-noise ratio values, network dimension and fading severity is discussed. Based on the presented results, the choice of internode protocol is considered a trade-off between the low-latency requirement and communication with no data loss.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"508 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132235487","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 geomagnetic field measurements require very precise instrumentation which is mostly spacious. On the other hand, the chosen magnetometer — HMC5883L — is very tiny but suffers from lower resolution and high noise floor. The objective is to examine possibility of geomagnetism investigation made by an integrated widespread magnetometer, to evaluate its precision and to detect some outer space events by geomagnetism observations. There was proposed and constructed measuring device including AMR chip. The measuring device including the AMR chip was proposed and produced. A long-term measurement was recorded in collaboration with the geomagnetic observatory Budkov, Czech Republic (Institute of Geophysics of the CAS, v. v. i.; INTERMAGNET). The post-processing was designed in order to suppress sensor noise and temp-drift. The post-processing used was standardized by INTERMAGNET especially for geomagnetic observatories. Finally, with the constructed device there were detected the day-night variations of the Earth magnetic field and a solar storm of 4th grade of k-index.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121348932","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 the proposed method propagation conditions between the localized objects and the anchors forming system infrastructure are classified into one of three categories: LOS (Line-of-Sight), NLOS and severe NLOS. Non-Line-of-Sight detection is conducted based on first path signal component power measurements. For each of the categories, average NLOS inducted time of arrival bias and bias standard deviation have been estimated based on results gathered during a measurement campaign conducted in a fully furnished apartment. To locate a tag, an EKF (Extended Kalman Filter) based algorithm is used. The proposed method of NLOS mitigation consists in correcting measurement results obtained in NLOS conditions and lowering their significance in a tag position estimation process. The paper includes the description of the method and the results of the conducted experiments.","PeriodicalId":422501,"journal":{"name":"2017 25th Telecommunication Forum (TELFOR)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115388386","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}
