A model of such four-resonator interdigital filter is made and the results of its experimental investigations are given.

A method for monitoring the performance of built-in protection systems of modern HF equipment is proposed if the output power exceeds the limits of allowable values under single fault conditions.

Business stability ensuring mechanism of enterprise model in modern economy digitalization conditions is grounded based on complex casual-consequential chains of business management metrics system of the enterprise with its marketing complex. Each component of the business management metrics system of the modern enterprise is proved to form particular components of the general model for business stability ensuring mechanism. Thus, the business stability of modern digital enterprises should be defined as a cortege (complex) of three consequently connected stability ensuring systems: «organizational stability < market stability < economic stability». Each system, in its turn, consists of components that are functional (operational) stability types. Each stability type factor should form through a logical combination of particular business policies range from proposed by the author matrix «business management metrics system — marketing complex» of particular strategic behavioral guidelines of the enterprise to interact with its target market within {i — business metrics; j — marketing complex} pair. Every behavioral guideline should include an appropriate economically grounded quantitative key (integral) indicator. Business stability of modern enterprise in transition to digital economy conditions is defined as a complex enterprise ability to react quickly and adequately to violations in the business processes of consumer business value creation chain for partners and customers trust maintenance, ensuring competitiveness and further continuous development of their business. The conclusion is that further problem study prospects of the enterprise business stability ensuring in modern market conditions may be connected with quantity trend analysis of business value creation chains for every business metric of modern digital (SMART) enterprise considering proposed by authors model for business stability ensuring mechanism creation based on strategic planning matrix «SBC-MM».","PeriodicalId":139019,"journal":{"name":"Measurements infrastructure","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131664028","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}

Comparisons of measurement standards are not performed often. Number of participants is limited. CMCs are difficult to obtain.

Interlaboratory comparisons and calibrations should be directly linked to comparisons of measurement standards in the Network. Interlaboratory comparisons initiated in the Network differ from comparisons of measurement standards only in the factor that they will be initiated for working measurement standards and instruments.

For those measurements, different metrological traceability chains are used, both in the international normative documents and at the national level. Different measurement standards used to calibrate breath analysers reproduce different quantities: on the one hand, an «actual» ethanol mass concentration, and, on the other hand, the operationally defined «ethanol mass concentration by Dubowski (or Harger)». This makes the comparability of the breath alcohol measurements questionable. According to various studies, the discrepancy between the operationally defined quantity and the concentration not related to the empirical interphase distribution coefficients, lays within (1-2) %, although there is also an evidence of a larger deviation. It is possible to construct a common metrological traceability chain by using reference gas mixtures in cylinders and dynamic gas mixture generators based on the principles not related to empirical equations, as well as determining more accurately the interphase distribution coefficient and evaluating its uncertainty. SE «Ukrmetrteststandart» possesses internationally recognised calibration and measurement capabilities for measuring ethanol concentration and producing reference materials: calibration gas mixtures of ethanol with nitrogen or air in cylinders and reference aqueous solutions of ethanol that provide metrological traceability for the breath alcohol measurements.","PeriodicalId":139019,"journal":{"name":"Measurements infrastructure","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134350488","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}

A hierarchical scheme for gas flow measuring instruments and a corresponding metrological traceability chain are presented. Described is a PVTt method, on which the primary standards of gas flow rate used in the USA, France, Japan, and Taiwan are based. The need to create in Ukraine primary measurement standards of gas flow rate at high pressure covering different parts of the total flow rate interval from 0,3 m3/h to 1800 m3/h at a pressure of 1 MPa to 5 MPa is substantiated. Metrological traceability of gas flow measurements is realized through a sequence of critical flow Venturi nozzles, which play a role of the reference flow rate material measures. The standards might be used to calibrate the primary reference Venturi nozzles of the most common 0,1 mm to 8 mm diameters. The characteristics and parameters of the standards are determined. By their metrological and technical characteristics, the standards will correspond to the state-of-the-art level. According to the programme of developing the measurement-standard facilities in Ukraine, in 2019 the primary standard PVTt-65 was created and work had started on the development of the primary standard PVTt-1800 and the working standard PE-5400. A detailed study of the metrological characteristics of the measurement standards will be the topic of further work.","PeriodicalId":139019,"journal":{"name":"Measurements infrastructure","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130684051","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}
