Multiple probes are required in a measurement setup for obtaining these correlation data. As the amount of data collected in such a measurement can be substantial, principal component analysis (PCA) can be utilized to reduce the complexity in the subsequent data processing and also for separating statistically independent sources. In cyclostationary problems, cycle frequencies need to be identified before formation of the correlation spectra. PCA is applied by an eigenvalue decomposition of the correlation matrix. Singular value decomposition of a Hankel matrix formed from the observed signal vector yields an identification of cycle frequencies.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"113 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123792949","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}

Industry, power plants, traffic, factories are the main pollutants in big cities. On the other hand, the same technological advancement can also be used to decrease this bad influence. One of the ways is a smart city sensor network with applications that can predict air quality for the next few days and warn the population in the case of the upcoming severe pollution. The prediction task in this paper is conducted by using state-of-the-art algorithms such as CatBoost, with additional features that help improve the quality of the model. Three models are examined, regular CatBoost, CatBoost with additional variable, and the new approach where CatBoost model is boosted with another model.

This antenna operates efficiently for three resonant frequencies - 25.57 GHz, 28.03 GHz, 30.25 GHz and this proves the successful operation of the antenna in two bands i.e. the K-band and Ka-band. To achieve this multi band nature, some slots in the front and the rear part of the antenna are utilised. The front patch of the antenna is made of copper and is devised in a peculiar dome shape which provides a novelty to this antenna. The antenna shows some great results when simulated giving an overall efficiency of more than 90%, A high gain is also recorded for the frequencies and an extremely high gain for 30.25 GHz. Furthermore, the return loss dips(S11) for the three resonant frequencies are stated to be below -30 dB and reaching to as low as -55 dB at the second resonant frequency.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127375782","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}

Interesting biomedical applications use cooperative sensors to monitor the patients’ health status. Such set of cooperative sensors, sometimes equipping wearable or implantable devices, constitute the so called Biomedical Measurement Systems (BMS). In this context, the cooperation among sensors is possible only if they share a common sense of time and the synchronization accuracy is a key factor for the accuracy and the reliability of the monitoring. In this paper a consensus based algorithm to overcome two typical synchronization challenges are taken into account: the trade-off accuracy versus network lifetime and the degradation of the synchronization accuracy in the case a new sensor is added in the network.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125952447","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}

Transmitting (Tx) and receiving (Rx) at the same time and over the same frequency channel results in significant improvements in communication systems throughput and spectral efficiency. The chief challenge associated with STAR systems is the required high Tx/Rx isolation that may be obtained with transceivers that combine multiple layers of self-interference (SI) cancellation including digital back-end processing. Since transceivers \"start and end\" with apertures, the antenna layer is therefore critically important for STAR operation. Nowadays, ~40-50% of the required isolation can be achieved with a well-designed IBFD antenna subsystem inching us ever closer to meeting this, not so long ago considered impossible task. This review focuses on the role of antennas in IBFD systems. Performances of various antennas designed to cover different bandwidths, fields of view, and concepts of use are overviewed. What was deemed impossible a decade ago is now likely.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114818017","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 ceramic materials, regarding higher miniaturization and integrations, the structure analysis is very important. The main contribution of this research is related to relation between perovscites ceramics electronic properties, especially BaTiO3 and NZT-ceramics and structural characteristics. We applied advanced analysis, based on fractal nature and introduced complex fractal correction in defining the very important electromagnetic parameter inductivity (L). The samples consolidation includes both, powder pressing (cold sintering) and hot sintering. The fractal characterization performs very important role from powders up to the final structures, through which exists structure influence on electro-physical and other ceramic properties. We report the experimental results of BaTiO3 and NZT-ceramics processing. Also, this is the first time that we apply complex fractal correction (influence of grains and pore surface and as well as particles Brownian motion) on fundamental thermodynamic temperature in Currie-Weiss law. This application includes the influence of Housdorff dimension (DH) from the microstructure images and connect fractal corrections in Currie-Weiss law, for relative dielectric constant ϵr and magnetic permeability μr. Through ϵr and μr, on this way, for the first time in this scientific area, we present direct relation to inductivity. This complex relation opens quit new advance understanding in structures and parameters in area of ferroelectic-magnetic applications in telecommunications, by introducing the fractals.","PeriodicalId":228464,"journal":{"name":"2021 15th International Conference on Advanced Technologies, Systems and Services in Telecommunications (TELSIKS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131305445","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}
