The first part of this paper is focused on the basic concepts of antenna systems. Next, the synthesis and design of an antenna array is described. Finally, the results of the simulation feeding network based on the SIW structure are presented along with verification of these results.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"5 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":"123299051","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}

We use a convolutional neural network (CNN) for bright lesions detection and evaluate achieved results using criterion based on proper comparison of each lesion with ground truth images scored by the ophthalmologist. As input data we use original and geometrically transformed retinal images from Messidor database divided into smaller blocks. In that way we enlarge the training dataset and increase classification accuracy.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"66 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":"124599259","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}

It introduces a number of different quality indicators (connected to the sharpness of image, the expression of subject and image contrast) and describes their effect on the results of the convolutional network. It attempts to give recommendations on the ideal values for these indicators in order to choose the best candidate from the video sequence on which to perform the recognition algorithm.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"7 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":"114469451","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 combinations are characterized by a large wavelength, which enables a robust ambiguity resolution even in the presence of uncorrected geometric and ionospheric biases at the price of a slightly increased noise level.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"1 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":"114081376","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 local-entropy-based algorithm has been introduced in literature as an automatic method for signal denoising, however its application has so far been limited to white noise removal. The algorithm's effects on signals corrupted by pink (flicker) and blue noise, reported in this paper, are consistently beneficial for signals with different noise power spectra, proving the algorithm's ability to perform well in various environments. The algorithms's performance in pink and blue noise is shown on examples of dolphin's and bat's calls.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"25 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":"125750716","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 this paper, we describe a Real-Time Kinematic (RTK) positioning method, that uses both GPS and Galileo measurements with a common reference satellite, estimates a pseudorange multipath error for each satellite to prevent a mapping of multipath errors into the position, and performs a hypothesis testing for ambiguity fixing. The proposed method is tested on the new Multi-Sensor, Multi-GNSS RTK positioning module of ANavS, which includes up to 3 GNSS receivers, an inertial sensor, a barometer and a processor for RTK positioning on a single board. The measurement results show a repeatable millimeter-level positioning accuracy.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"172 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":"132520544","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}

Decision makers in the public sector have been facing budgetary restrictions along with significant market demand for new technologies. The solution could be found in private sector participation. The main aim of such cooperation is the risk and reward principle. Both the public and the private sectors retain their own identity and responsibility while the co-operation is based on clearly defined divisions of tasks and risks. The private sector has a new opportunity to raise maximum value for money while the public sector can deliver better quality of infrastructure at lower prices or same quality but with significant savings.","PeriodicalId":175742,"journal":{"name":"2018 International Symposium ELMAR","volume":"37 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":"129519632","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}
