These filters are a part of the input circuits of the analog-to-digital interface of the instrumentation and control systems (ICSs) and serve to reduce the value of the aliasing error (the anti-alias filters). The signal delay in the filters causes significant dynamic errors in the instrumentation and control systems that reduce the tolerance frequency of the sensor signal sampling. Using the Filter Solution application programs and the NI LabVIEW software environment the analytical expressions for the delay times of three types of filters at linear and polynomial approximation were obtained. The analysis of the obtained results enabled us to turn attention to the significant value of the dynamic errors due to the signal delay of the sensor in the anti-alias filter that makes their use in some instrumentation systems problematic.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125508497","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}

Unlike the traditional radiochemical deactivation methods, which form the large volume of a liquid radioactive waste (LRW), the proposed technology allows to condense the removed radionuclides in a compact solid form. This technology is important both for the decommissioning of a NPP (including the deactivation of irradiated reactor graphite) and in the current operations and planned repairs of nuclear reactors. In addition, the another important opportunity of the technology is producing of new materials like a beta-active “nano-micro-sandwich” (enriched with radioisotope 14C or other.) for the useful applications, e.g. in a nuclear medicine and for a new type of betavoltaic batteries.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123089120","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 is typically done by fitting kinetic models to experimental data, which are mostly multivariate nowadays. These data often bear ill properties like noise and/or rank deficiency, which may ruin the relevance of the obtained results. In the present work we tested the ability of three well defined multivariate curve resolution approaches (model-free MCR-ALS, model-based MCR-ALS and full-matrix non-linear least square fit) to recover rate constants from simple simulated kinetic data when the spectra of components are almost linearly dependent. Model-free estimation of concentrations produced incorrect estimates. Model-based analysis was possible, but the quality of estimates of rate constants and convergence were strongly degraded by rank deficiency. Full-matrix non-linear least square fit displayed the best results both with respect to accuracy of the estimates and calculation performance. It proved its known value of the method of choice. The quality of the estimates depended strongly on the ratio between the rate constants: cases with highly similar and highly dissimilar rate constants were more problematic. The reasons of poor convergence of ALS algorithms and sources of bias in the estimates of rate constants are discussed.","PeriodicalId":296618,"journal":{"name":"2018 IEEE International Conference on Electrical Engineering and Photonics (EExPolytech)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122285176","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}
