{"title":"ANALYSIS OF THE METHODS FOR THE DETERMINATION OF THE MINIMUM REFLECTION CHARACTERISTIC IN THE PROCESS OF THE SURFACE PLASMON RESONANCE (Ukr)","authors":"H. Dorozinska","doi":"10.31649/2307-5376-2020-1-1-7","DOIUrl":"https://doi.org/10.31649/2307-5376-2020-1-1-7","url":null,"abstract":"The paper analyzed the most widely used methods for the determination of the reflection characteristic minimum in the process of the surface plasmon resonance and considers the impact of the refraction index change of the studied environment and its temperature on the accuracy of the measurements, performed by these methods, applying the numerical modeling. It is known that the accuracy of the minimum reflection characteristic determination greatly depends on the mathematical methods of its determination. The most widely used methods of the minimum reflection characteristic determination are the methods of the polynomial approximation, which depend on the form of the reflection characteristic, that influences the accuracy of the minimum determination. The developed alternative method of the center line provides smaller measurement error when the refraction indices change from 1.33 to 1.5 times as compared with the methods of the polynomial approximation for the area of the reflection characteristic with the angular range of 0.125 ang. deg. and almost 8.5 times for the angular range of 0.2 ang. deg, that proves the expediency of the new method application. The smallest absolute error is characteristic for the method of the center line for the area of the reflection characteristic of 0.4, that is connected directly with the number of points, comprising the area of the minimum determination. The method of the center line, used for the study of the temperature changes of the analyte also provides smaller absolute error of minimum determination as compared with the polynomial approximation and has smaller error values scattering in the range of the higher temperatures. As compared with the polynomial methods the center line method has higher accuracy of the determination of the reflection characteristic minimum, because it is less dependent on its asymmetry, which is connected with the flow of the physical processes on the surface of the surface of the plasmons excitation. The results of the numerical analysis, carried out, may be useful for the development of the algorithms of the direct measurements processing by measuring devices on the base of the surface plasmon resonance.","PeriodicalId":404659,"journal":{"name":"Scientific Works of Vinnytsia National Technical University","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132824214","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}

Yukhymchuk","doi":"10.31649/2307-5376-2022-3-10-20","DOIUrl":"https://doi.org/10.31649/2307-5376-2022-3-10-20","url":null,"abstract":"The important component for the solution of the problem of decentralized coordination of the distributed cyber-physical systems (DCPS) control is obtaining of the primary information, needed for searching the optimal control. Such information may be divided into conditional constant – the parameters of the controlled object, and variable – state of the controlled object. Determination of the object parameters is carried out by means of identification problem solution. Object persistence and correspondingly, the possibility of changing its elements state during the coordination cycle stipulates the need to forecast the processes in DCPS. In greater part of the research, dealing with the forecasting problem methods are considered where in this or that way expert assessments and conclusions are used. This concerns mainly social-economic processes, forecasts in the sphere of medicine, education, etc. In the given study the forecasts for the cyber-physical systems are considered, although, in this case models of physical processes and formal methods of the forecasting play far more important role , however, at certain stages expert assessments are also used, in particular, regarding the ranges of possible change of the parameters, list of influencing factors, etc. The prediction method of the state of the distributed cyber-physical systems with the continuous objects on the base of space-time spectral approach to the prediction of DCPS state with continuous and discrete object states has been improved, study of the characteristic of DCPS state prediction has been performed. The possibility of the realization of the prediction method, using the machine learning and simulation modelling has been considered. The expediency of the prediction depth as with the increasing of the depth (interval) of the prediction the fuzziness of the prediction results increases. At the same time, computational resources and time are spent for the prediction. Gradually the situation arises, when the positive effect of the prediction becomes less than the expenses for its realization, this determines the expedient maximum depth of the prediction.","PeriodicalId":404659,"journal":{"name":"Scientific Works of Vinnytsia National Technical University","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122067653","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}
