At the beginning, the article presents issues related to the subject of the need to analyze the quality of electricity. Then the phenomenon of “spectrum leakage” is discussed. For selected test signals, FFT spectral analysis was carried out using the MATLAB program. In the next part, a constructed measuring station is presented, which enabled the analysis of the considered phenomenon based on actual experimental research. In addition, for the same signals, a simulation test was carried out. Metrological interpretation of the obtained results and formulations of conclusions were presented in the paper.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115201201","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 calibration function estimated from the calibration experiment is further used for predicting the value of the unobservable stimulus from the future indication (measured response) received by using the calibrated measurement device, together with its associated measurement uncertainty. In this contribution, we present a brief overview of results known for linear and polynomial comparative calibration and raise a natural question about the effect of using inverse relationship in modeling the calibration function, i.e., by changing the standard roles of the stimulus and the response in the considered calibration function.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122495482","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}

Body surface potential maps (BSPMs) measured during stimulation by a catheter in the right ventricle were recorded in 116 leads on the patient torso. Patient's ventricular model was used to simulate the initial depolarization started in positions close to the catheter position and corresponding BSPMs were computed. Correlations between the recorded and simulated BSPMs were computed during 20 ms at the beginning of the activation. The best mean correlation between the measured and simulated BSPMs was 0.89 or 0.91 for homogeneous or inhomogeneous torso model, respectively. The distance between the real position of the stimulating catheter and the starting points used for the best BSPMs was 23 or 22 mm. The simulations using the proposed model could serve for additional verification of the results obtained by the inverse solution when finding the origin of premature ventricular activation.","PeriodicalId":129350,"journal":{"name":"2019 12th International Conference on Measurement","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126586896","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}

Dynamical systems are a useful tool for modeling many real-world processes. The subject of this work is the detection of causality between two dynamical systems.
