The influence of scintillators volume and irradiation geometry on the MDA evaluation of the measurement uncertainty was studied. It is shown that the estimated expanded MDA measurement uncertainty interval on 137Cs is 21—23 per cent. The absolute value of the MDA measurement uncertainty when changing geometry of irradiation increases 10 times. Change in the volumes of the examined PS causes a change of MDA measurement uncertainty within 10 per cent.","PeriodicalId":308704,"journal":{"name":"2019 IEEE 8th International Conference on Advanced Optoelectronics and Lasers (CAOL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130088859","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 realizations of the process (input and output signals) are converted to the sum of individual components (modes) based on the Hilbert-Huang transform, and then the corresponding modes of this transformation are used for the virtual subsystem identification. The identification quality depends on the measurement uncertainty of both the signal and its Hilbert-Huang modes. The influence of measurements uncertainty of the signal on the individual modes’ uncertainty, considering important factors, is analyzed in the article. The obtained results extend the conditions for solving the problems of system identification.","PeriodicalId":308704,"journal":{"name":"2019 IEEE 8th International Conference on Advanced Optoelectronics and Lasers (CAOL)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129158034","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 was found that with an increase in the concentration of nanoparticles to a value of 4•10−4 mM, the emission energy of nanocomposites increases. It was observed both for nanocomposites containing one dye and for nanocomposites with a mixture of these dyes, between the molecules of which donor-acceptor transfer of excitation energy is possible. It is shown that the increase in emission energy is due to the appearance of strong plasmon-induced optical pumping fields in the vicinity of the nanoparticles. In a nanocomposite with a donor-acceptor mixture of dyes, strong local fields arise not only at the pump radiation frequency but also at the donor emission frequency. This is equivalent to an increase in the efficiency of excitation energy transfer in the donor-acceptor pair of molecules. The effect of an increase in the excitation rate prevails with an increase in the concentration of nanoparticles to a value of 4•10−4 mM. With a greater concentration of nanoparticles, the losses due to nanoparticle scattering and absorption become significant, which leads to a decrease in the lasing energy.","PeriodicalId":308704,"journal":{"name":"2019 IEEE 8th International Conference on Advanced Optoelectronics and Lasers (CAOL)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127643550","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 was shown that laser light is not able to decrease the constant of association especially with liposomes containing cardiolipin. Mechanisms of established effect are under consideration.
