A new method of justification of the requirements for measuring equipment (ME) is proposed. For the first time, the method accounts for the potential variability of the product structure during its intended use, and thus, allows minimizing the requirements concerning the probability of estimating the values of diagnostic parameters of the product during its current repair (CR), thereby reducing the cost of ME. In addition, partial (in particular, time between failures and average recovery time) and multi-component (in particular, the readiness/non-readiness factors) values of the reliability indices are quantitatively estimated and which meet the requirements. The task is solved algorithmically using the approaches of technical diagnostics and metrology. Based on the prescribed requirements for the reliability indices of the product, the justified ME for CR is selected. To achieve the goal, recent advances in modelling the reliability of large-scale facilities and systems with variable structure, as well as metrology methods for assessing the impact of the reliability of the ME on the value of the average recovery time of multimode facilities during their CR are involved. To our best knowledge, the application of these possibilities has not been reported yet. The paper formalizes the procedure for applying the obtained results in the form of an algorithm, which allows increasing the efficiency of the method, benefiting from its advantages. The application of the proposed method is illustrated for a piece of real communication equipment, namely a subsystem controlling the functioning of a high-power radio transmitter. It is demonstrated that, based on the requirements stated in the guidance documents regarding the value of the average recovery time of an object with variable structure, the selection of metrological characteristics and type of ME can be justified. Alternatively, the problem can be solved based on the given value of the reliability index of a multicomponent product, the so-called readiness factor. An example of assessing the efficiency by the proposed method is presented. The proposed method is recommended for the development of metrological support for CR of prospective radio-electronic tools with variable structure.
提出了一种证明测量设备(ME)要求合理性的新方法。该方法首次考虑到了产品结构在预期使用期间的潜在变化,因此可以最大限度地降低对产品当前维修(CR)期间诊断参数值估计概率的要求,从而降低测量设备(ME)的成本。此外,还能定量估算出符合要求的部分(特别是故障间隔时间和平均恢复时间)和多组件(特别是就绪/未就绪系数)可靠性指数值。这项任务是利用技术诊断和计量学方法通过算法解决的。根据对产品可靠性指数的规定要求,为 CR 选择合理的 ME。为了实现这一目标,需要对大型设施和可变结构系统的可靠性进行建模,并采用计量学方法评估多模设施在 CR 期间 ME 的可靠性对平均恢复时间值的影响。据我们所知,这些可能性的应用尚未见报道。本文以算法的形式正式确定了应用所获结果的程序,从而提高了该方法的效率,并从其优势中获益。本文以实际通信设备为例,说明了所提方法的应用,即控制大功率无线电发射机运行的子系统。结果表明,根据指导文件中对可变结构物体平均恢复时间值的要求,可以合理选择计量特性和 ME 类型。另外,还可以根据多组件产品的可靠性指数给定值(即所谓的准备系数)来解决问题。本文举例说明了如何利用所建议的方法评估效率。建议使用所提出的方法为具有可变结构的未来无线电电子工具的 CR 提供计量支持。

As of today, Ukraine maintains a number of primary radio measurement standards established at the end of the last century. However, there is an abundance of high-tech multi-functional measuring equipment being widely spread for the purpose of metrological support (verification, repair, calibration). This circumstance requires the adaptation of the domestic infrastructure of metrological support and revision of the principles and approaches to the metrological support system itself. The essence of the new approach lies in the maximum use of both our methodological experience in metrology and technological solutions of modern instrumentation. When establishing a new primary measurement standard for frequency deviation, these new principles are implemented. The paper shows that the main tendencies in the instrumentation in the field of electro-radio measurements are not only aimed at the improvement of metrological characteristics, but also at the wide use of digital and software solutions, which requires new approaches to metrological support. The experience of developing the primary measurement standard for frequency deviation of frequency-modulated (FM) oscillations, as well as the study of the measurement standard for amplitude-modulated (AM) oscillations, shows the effectiveness of using digital methods for the generation of precise complex broadband signals, and software methods for the implementation of complex measurement algorithms. Thanks to the programming, such methods as “zeros of the Bessel function” and “combination frequencies” have been implemented, which in the analogue version are very cumbersome and difficult to apply in practice. The experimental estimation of metrological characteristics of the most important equipment devices (generators and demodulators) during their operation by analogue and digital methods is described, and the results of comparative measurements are given. It is shown that, in addition to the increasing number of metrological capabilities, digital and software approaches allow creating flexible multifunctional calibration complexes in the field of radio measurements.
截至目前,乌克兰仍保留着上世纪末制定的一系列无线电测量主要标准。然而,大量高科技多功能测量设备正在广泛传播,用于计量支持(验证、维修、校准)。在这种情况下,需要对国内的计量支持基础设施进行调整,并对计量支持系统本身的原则和方法进行修订。新方法的精髓在于最大限度地利用我们在计量方法方面的经验和现代仪器的技术解决方案。在建立新的频率偏差主要测量标准时,这些新原则得到了贯彻。本文表明,无线电测量领域仪器设备的主要发展趋势不仅在于改进计量特性,还在于广泛使用数字和软件解决方案,这就需要新的计量支持方法。制定频率调制(FM)振荡频率偏差初级测量标准的经验,以及对幅度调制(AM)振荡测量标准的研究表明,使用数字方法生成精确复杂的宽带信号,以及使用软件方法实施复杂的测量算法,都是非常有效的。通过编程,"贝塞尔函数的零点 "和 "组合频率 "等方法得以实现,而这些方法在模拟版本中非常繁琐,难以实际应用。文中介绍了模拟和数字方法对最重要设备(发生器和解调器)运行期间计量特性的实验估算,并给出了比较测量的结果。结果表明,除了不断增加的计量功能外,数字和软件方法还可以在无线电测量领域创建灵活的多功能校准综合体。

Visual lighting effects have been seriously studied for more than 500 years. It was not until 2002 that physicians and biologists paid attention to the fact that the light that enters the human eye has non-visual, biological effects. Human Centric Lighting (HCL) examines the visual effects of light on human activity. Electric lighting plays a critical role in maintaining human health in today’s world, as most of us spend much of our time indoors. In 2002, a third type of photoreceptor was discovered – a nerve node cell in the retina (photosensitive, Retinal Ganglion Cell, pRGC). pRGC cells contain melatonin pigments (melanopsin) and are responsible for the spectral response of photosensitive cells. The maximum response of melatonin is achieved at a wavelength of approximately 480 nm. Fig. 1 also shows the response curves of L-, M-, and S-cones and rods based on their specific pigments. Using the response curves of L-, M-, and S-cones and rods, and having the spectra of light sources and the amount of light on the outer surface of the eye, it is possible to determine the spectrally weighted illuminances for five photopigments in the human eye. For research purposes, it is desirable to record the illuminance values for all five α illuminances. They indicate which of the photoreceptors is responding and where the light of the current lamp type is emitting. The manufacturers of light sources should be able to provide α-wave illuminances for their lamps. The International Commission on Illumination (CIE) suggested Exeltoolbox, which allows calculating these illuminances based on the spectral distribution of the lamp power. Cone-dominant metrics such as CCT (correlated colour temperature), illuminance, and luminance are not comprehensive, so melanopsin-based photosensitivity should be considered in specifications, guidelines, and during research.
对视觉照明效果的认真研究已有 500 多年的历史。直到 2002 年,医生和生物学家才注意到,进入人眼的光线具有非视觉的生物效应。以人为本的照明(HCL)研究了光对人类活动的视觉影响。在当今世界,电气照明在维护人类健康方面发挥着至关重要的作用,因为我们大多数人的大部分时间都是在室内度过的。2002 年,人们发现了第三种光感受器--视网膜上的神经节细胞(光敏视网膜神经节细胞,pRGC)。pRGC 细胞含有褪黑激素色素(黑光素),负责光敏细胞的光谱响应。褪黑激素的最大反应波长约为 480 纳米。图 1 还显示了 L 锥体、M 锥体、S 锥体和杆状体根据其特定色素的响应曲线。利用 L 锥体、M 锥体、S 锥体和视杆细胞的响应曲线以及光源的光谱和眼睛外表面的光量,可以确定人眼中五种光色素的光谱加权照度。出于研究目的,最好记录所有五种 α 照度的照度值。它们表明哪个光感受器正在作出反应,以及当前灯泡类型的光正在向哪里发射。光源制造商应能提供其灯具的 α 波照度。国际照明委员会(CIE)建议使用 Exeltoolbox,它可以根据灯功率的光谱分布来计算这些照度。CCT(相关色温)、照度和亮度等锥形主导指标并不全面,因此在规格、指南和研究过程中应考虑基于黑色素的光敏性。

The creation of a scientifically substantiated quality assurance system for dosimetry and the optimization of medical exposure of the population of Ukraine during diagnostic and therapeutic procedures (and the possibility of dosimetric control and monitoring of emergency situations) falls within the field of the application of ionizing radiation sources (IRs). Trends in modern medicine in most countries, including Ukraine, prove a continued increase in the share of medical exposure. The main requirements and recommendations for the use of IRs for medical purposes while ensuring the radiation safety requirements for patients are provided in the documents of such International Organizations as the International Commission on Radiological Protection (ICRP), the International Atomic Energy Agency (IAEA), the World Health Organization (WHO) and the European Commission (EC). One of the key factors to ensure the quality of radiation therapy is metrological and dosimetric support. To enhance the effectiveness of radiation treatment and reduce the number of complications in the future, it is necessary to irradiate the local target within the patient’s body with a dose error of no more than 5%. Control of the radiation output of the therapeutic device, i.e., the calibration of the therapeutic beam used in the treatment process, is an essential element of radiation therapy. Radiation protection programmes are based on checking the accuracy of the calibration of remote radiotherapy devices using thermoluminescent dosimeters (TLDs) – small plastic capsules filled with thermoluminescent powder that are sent by post to radiology centres for exposure to a specific dose in a water phantom. Radiation therapy in Ukraine is primarily conducted using cobalt machines, X-ray therapy devices and linear accelerators. The results of the study include the examination of the dependency of measurement results on various exposure parameters using the automatic reader PCL-3, the determination of dosimetric characteristics of the thermoluminescent powder TLD-100, and the development of a calibration method for thermoluminescent dosimeters under standard irradiation conditions on a remote gamma therapy device. Therefore, the accuracy of beam calibration using TLD dosimeters has been studied, which will enable to timely detect errors in clinical dosimetry and reduce the number of cases of radiation-related complications for patients during their treatment.
在诊断和治疗过程中,为剂量测定和优化乌克兰居民的医疗照射(以及对紧急情况进行剂量测定控制和监测的可能性)建立一个有科学依据的质量保证系统属于电离辐射源(IRs)应用领域。包括乌克兰在内的大多数国家的现代医学趋势证明,医疗照射的比例在持续增加。国际辐射防护委员会(ICRP)、国际原子能机构(IAEA)、世界卫生组织(WHO)和欧盟委员会(EC)等国际组织的文件中规定了将电离辐射源用于医疗目的并确保患者辐射安全的主要要求和建议。 确保放射治疗质量的关键因素之一是计量和剂量测定支持。为了提高放射治疗的效果,减少未来并发症的数量,有必要对患者体内的局部目标进行照射,剂量误差不得超过 5%。控制治疗设备的辐射输出,即校准治疗过程中使用的治疗光束,是放射治疗的基本要素。 辐射防护计划的基础是使用热释光剂量计(TLDs)检查远程放射治疗设备校准的准确性,热释光剂量计是一种装有热释光粉末的小塑料胶囊,通过邮局寄往放射中心,在水模型中接受特定剂量的照射。 乌克兰的放射治疗主要使用钴机、X 射线治疗设备和直线加速器。 研究结果包括使用自动阅读器 PCL-3 检验测量结果对各种照射参数的依赖性,确定热释光粉 TLD-100 的剂量学特性,以及在远程伽马治疗设备的标准照射条件下开发热释光剂量计的校准方法。 因此,研究使用热释光剂量计进行射束校准的准确性,可以及时发现临床剂量测定中的误差,减少患者在治疗过程中出现与辐射相关的并发症。

In accordance with the stated purpose of the study, the measurements and analysis of photodiodes were carried out, and the best alternative for the development of the trap detector was chosen. The paper substantiates the necessity for an alternative to the absolute cryogenic radiometer because of its highly expensive measurements. The need for more accurate measurement data has determined the use of trap detectors, including self-calibrating photodiodes. Such trap detectors can be used independently, without calibration by an absolute cryogenic radiometer. Thus, the cost of the study is reduced. Besides, the given approach does not affect the accuracy of the obtained measurement results. When reviewing modern approaches to the use of the above-mentioned trap detectors, it was discovered that trap detectors, together with self-calibrating photodiodes, are widely used both in state measurements of photometric quantities and for laboratory needs in many developed countries worldwide. The given analysis allows us to assert that the issues of developing, studying, and using new trap detectors, considering a significant advantage in their characteristics in comparison with the previously developed ones, make up an urgent scientific task. The paper defines selection criteria based on certain characteristics of photodiodes. When investigating the operating spectral range of the selected photodiodes, their internal quantum efficiency, geometrical dimensions of the receiving element of the selected photodiodes, and the coefficient of mirror and diffuse reflection of the receiving surface of the selected photodiodes, measurement results for all the stated characteristics were obtained. Based on these values, a screening of the photodiodes that do not meet the requirements for photodiodes specified for the development of the trap detector was made. Based on experimental studies, photodiodes S1337-1010BQ were selected.
根据研究的既定目标,对光电二极管进行了测量和分析,并选择了开发陷阱探测器的最佳替代方案。论文证实,由于绝对低温辐射计的测量费用非常昂贵,因此有必要为其提供替代品。对更精确测量数据的需求决定了陷阱探测器的使用,包括自校准光电二极管。这种陷阱探测器可以独立使用,无需绝对低温辐射计校准。因此,研究成本得以降低。此外,这种方法也不会影响测量结果的准确性。 在研究使用上述陷阱探测器的现代方法时,我们发现陷阱探测器与自校准光电二极管一起,在光度测量的状态测量和实验室需求中得到了广泛应用。通过上述分析,我们可以断言,开发、研究和使用新型陷阱探测器是一项紧迫的科学任务。 本文根据光电二极管的某些特性确定了选择标准。在对所选光电二极管的工作光谱范围、内部量子效率、所选光电二极管接收元件的几何尺寸以及所选光电二极管接收表面的镜面反射和漫反射系数进行研究时,获得了所有所述特性的测量结果。根据这些数值,筛选出了不符合开发陷阱探测器对光电二极管要求的光电二极管。根据实验研究,选定了光电二极管 S1337-1010BQ。

The main stages of calibration of measuring instruments are described.

The issue of replacing the term “upravlinnya/keruvannya” with the term “management” in the DSTU ISO 9000 series of standards is considered. The initiators of the replacement believe that the authors of the national standard DSTU ISO 9000:2015 Quality management systems. Fundamentals and vocabulary made erroneous translation of the term “management”, since the concept of “management” has a much broader meaning than the concept of “upravlinnya/keruvannya”, and this negatively affects the development of the Ukrainian economy. The initiators of the replacement insist on the immediate correction of this error in the DSTU ISO 9000 series of standards. To support these claims, the initiators have amassed numerous expert opinions, comments and other materials, the basis of which was the Russian-language edition of the ISO 9000:2015 standard, as well as long ago cancelled and replaced standards in the field of quality management. The reference to Russian-language publications is based on the fact that Russian is one of the three official languages of the ISO. The proposed replacement of the translation of the term “management” in the standard DSTU ISO 9000:2015 Quality management systems. Fundamentals and vocabulary was analysed. The equivalence of the concepts of “upravlinnya/keruvannya” and “management” is substantiated. The examples demonstrating the erroneous interpretation of the concept of “management” are given. Complying with the requirements of 6.1.5 DSTU 1.5:2015 National standardization. Rules of development and presentation of national normative documents for the use of foreign words and terms in the presence of equivalent words and terms in the Ukrainian language is stressed.
审议了在DSTU ISO 9000系列标准中用“管理”一词代替“upravlinnya/keruvannya”的问题。更换的发起者认为,国家标准DSTU iso9000:2015质量管理体系的作者。基础知识和词汇错误地翻译了“管理”一词,因为“管理”的概念比“upravlinnya/keruvannya”的概念具有更广泛的含义,这对乌克兰经济的发展产生了负面影响。更换的发起者坚持立即纠正DSTU ISO 9000系列标准中的这一错误。为了支持这些主张,发起者收集了大量专家意见、评论和其他材料,其基础是俄语版iso9000:2015标准,以及很久以前取消和替换的质量管理领域标准。提到俄文出版物是因为俄文是ISO三种正式语文之一。建议替换标准DSTU iso9000:2015质量管理体系中“管理”一词的翻译。分析了基础知识和词汇。“upravlinnya/keruvannya”和“管理”概念的等价性得到证实。举例说明了对“管理”概念的错误解释。符合6.1.5 DSTU 1.5:2015国家标准化要求。强调了在乌克兰语中存在等价词和术语的情况下使用外来词和术语的国家规范性文件的制定和呈现规则。

High voltages of alternative current (AC) are important because they are needed for numerous applications in physics and engineering. High AC voltages are also used to test insulating materials for their dielectric properties. Calibrations of instruments for high-voltage measurements should provide metrological traceability to national standards. This applies to the requirements for both voltage measuring instruments and current measuring instruments. The transformer for high-voltage measurements is used to reduce the values of currents and voltages during measurements in high-voltage electrical networks. Voltage transformers (VTs) are used to accurately measure high AC voltages. Current transformers (CTs) are used to convert line currents in power systems to levels that are acceptable for other measuring instruments, which are necessary to trip protective devices. There are measuring installations that are well known for accurate measurements of the CT coefficient for large primary currents, and systems for determining the behaviour of the industrial current and VT under distorted waveforms, etc. The calibration of a high voltage measuring system must be traceable to national or international measurement standards. Mutual comparisons of calibration results of CT and VT standards are carried out with the participation of several national laboratories. The results of high voltage transformer measuring systems (GULFMET.EM-S6) and high current transformer measuring systems (GULFMET.EM-S7) supplementary comparisons are described. The comparisons were carried out between national laboratories from three Regional Metrology Organizations. In general, the participants of both comparisons have demonstrated a good agreement of the results in the ratio error and phase displacement for high voltage and current. The comparison results may be used to improve the participants’ existing calibration and measurement capabilities entries in the Key Comparison Database (KCDB) of the International Bureau of Weights and Measures  (BIPM).
交流电(AC)的高电压是重要的,因为它们在物理和工程中的许多应用中都需要。高交流电压也用于测试绝缘材料的介电性能。高压测量仪器的校准应提供国家标准的计量可追溯性。这适用于电压测量仪器和电流测量仪器的要求。用于高压测量的变压器用于在高压电网中测量期间降低电流和电压值。电压互感器(VT)用于精确测量高交流电压。电流互感器(CT)用于将电力系统中的线路电流转换为其他测量仪器可接受的水平,这些测量仪器是跳闸保护装置所必需的。有一些测量装置是众所周知的,用于精确测量大一次电流的CT系数,以及用于确定失真波形下工业电流和VT行为的系统等。高压测量系统的校准必须可追溯到国家或国际测量标准。在几个国家实验室的参与下,对CT和VT标准的校准结果进行了相互比较。介绍了高压变压器测量系统(GULFMET.EM-S6)和大电流变压器测量系统的补充比较结果。这些比较是在三个地区计量组织的国家实验室之间进行的。总的来说,两次比较的参与者都证明了高电压和高电流的比率误差和相位位移结果的良好一致性。比较结果可用于改进国际度量衡局(BIPM)关键比较数据库(KCDB)中参与者现有的校准和测量能力条目。

The paper considers the development and implementation of a method for integral assessment of the application level of the multipurpose real estate cadastre at the regional level. Factors affecting the formation and application of the multipurpose real estate cadastre are singled out. The technology for the formation of information-analytical and spatial support of the results of an integrated assessment deserves attention. In addition, the European experience of forming and applying the multipurpose cadastre, determining the factors affecting its creation, and constructing a theoretical and methodological platform for the real estate identification is systematized. In modern conditions, the creation of a quantitative basis for the formation and application of the multipurpose real estate cadastre is realized applying the method of integral assessment for making reasonable management decisions at the regional level and developing recommendations for increasing the efficiency of the real estate use. Based on the formed quantitative basis based in turn on the results of an integral assessment, it is proposed to carry out mathematical modelling and determine the points of growth of the efficiency of the use of the real estate at the regional level using a multipurpose cadastre. The impact of spatial, urban planning, investment and environmental factors on the formation and application of the multipurpose real estate cadastre is determined.

A proposed new definition of measurement uncertainty 提出了测量不确定度的新定义
IF 0.1 Pub Date : 2023-07-05 DOI: 10.24027/2306-7039.2.2023.286696
Walter Bich
A new definition of the measurement uncertainty (MU) was proposed by the Working Group 1 of the Joint Committee for Guides in Metrology, JCGM-WG1. This definition avoids any quantitative aspect of the measurement uncertainty and focuses on its subjective nature. The proposed new definition reads as follows: doubt about the true value of the measurand that remains after making a measurement. Here, MU is no longer quantitative; it is rather a (subjective) state of mind. MU is the concept, and its quantitative measures, such as the standard measurement uncertainty, are different in nature. This separation greatly contributes to clarity. Being defined as a state of mind, MU is subjective and reflects the belief of the experimenter in the result. There is no “true uncertainty” in nature to be estimated. There exists the measurand, and the uncertainty about its true value is a personal matter. Of course, the state of belief is based on objective data, and a good experiment is conceived in such a way as to minimise subjectivity. Yet, the hope to eliminate subjectivity from a measurement or from science at large is just a hope. The proposed new definition explicitly uses the term “true value”. Perhaps, at the philosophical level, the concept can be questioned, whereas in the context of parameter estimation, the mathematics behind calculations needs a unique true value, which is ideally represented by a unique real number. The doubt is about the unknown value of the measurand, not about the estimate. The estimate is viewed as a realization of a random variable describing the state of knowledge about the measurand. As such, the estimate is fixed and has no uncertainty. Randomness is in the variable, not in its realizations.
计量指南联合委员会JCGM-WG1第一工作组提出了测量不确定度的新定义。该定义避免了测量不确定性的任何定量方面,并侧重于其主观性质。拟议的新定义如下:对测量后剩余的被测量值的真实值表示怀疑。在这里,MU不再是定量的;这是一种(主观的)心态。MU是一个概念,其定量测量,如标准测量不确定度,本质上是不同的。这种分离极大地提高了清晰度。MU被定义为一种精神状态,它是主观的,反映了实验者对结果的信念。自然界中不存在“真正的不确定性”。被测量是存在的,其真实值的不确定性是个人的事情。当然,信仰状态是基于客观数据的,一个好的实验是以尽量减少主观性的方式构思的。然而,希望从测量或整个科学中消除主观性只是一种希望。拟议的新定义明确使用了“真正的价值”一词。也许,在哲学层面上,这个概念可能会受到质疑,而在参数估计的背景下,计算背后的数学需要一个唯一的真值,理想情况下用一个唯一实数来表示。怀疑的是被测值的未知值,而不是估计值。该估计被视为描述被测量知识状态的随机变量的实现。因此,估计是固定的,没有不确定性。随机性存在于变量中,而不存在于其实现中。
