Abstract (sommario):

Series of GNSS receiver tests allowed to determine real accuracy of RTN measurements. Repeated measurements allowed to estimate accuracy in function of used navigation satellite system, duration of measurements and field conditions on measurement site which are related to horizon visibility by obstacles (bushes). Research results indicate no dependency between the technology used and the measurement accuracies obtained and significant impact of the conditions on set-up on the measurement's results.

Abstract (sommario):

To assess the reliability of dc energy measurement equipment on-board trains, a setup was developed to characterize current transducers under realistic operating conditions. The operating principle is based on a current ratio measurement technique. The reference sensor is a high-precision zero-flux current transducer in combination with a broadband high-precision current shunt. The influence of ac distortion on this reference sensor was found to be within a few parts in 10 <sup>6</sup> using an initial version of the setup, in which ac distortion was applied through a separate windin

Abstract (sommario):

In this paper, we generalize the notion of measurement error on deterministic sample datasets to accommodate sample data that are random-variable-valued. This leads to the formulation of two distinct kinds of measurement error: intrinsic measurement error, and incidental measurement error. Incidental measurement error will be recognized as the traditional kind that arises from a set of deterministic sample measurements, and upon which the traditional measurement error modelling literature is based, while intrinsic measurement error reflects some subjective quality of either the measurement too

The electroacoustic measurement model is an explicit model of an entire ultrasonic measurement system, including the pulser/receiver, cabling, and transducers. A summary is given of the measurement procedures needed for characterizing all the system elements contained in this measurement model, including a description of a new pulse-echo method for obtaining the sensitivity and impedance of an ultrasonic transducer. It is demonstrated that these models and measurement procedures can be combined to accurately simulate the measured voltage of a pulseecho immersion system.

With the ongoing progress of optoelectronic components, laser-based measurement systems allow measurements of position as well as displacement, strain and velocity with unbeatable speed and low measurement uncertainty. The performance limit is often studied for a single measurement setup, but a fundamental comparison of different measurement principles with respect to the ultimate limit due to quantum shot noise is rare. For this purpose, the Cramér-Rao bound is described as a universal information theoretic tool to calculate the minimal achievable measurement uncertainty for different measure

ABSTRACT THE EVALUATION AND treatment of spinal deformities begins with the accurate measurement of appropriate spinal parameters. The surgeon must ensure that the patient is positioned properly for all necessary x-ray scans and that the proper studies are completed. The relevant measurements must be identified and recorded for each study. Understanding the proper measurement techniques will increase the accuracy and reliability of the measurements. From these precise measurements the surgeon can begin to determine key characteristics of the deformity and develop an appropriate treatment plan.

Neutron reflectometry (NR) is a powerful technique for interrogating the structure of thin films at interfaces.

Abstract (sommario):

Product and process conformance are determined by measurements that are taken by a measurement system. A clear understanding of the results of any measurement system requires an understanding of the possible errors within this system. Measurement system errors can be classified into two categories: accuracy and precision. The accuracy of a measurement system is usually broken into three components: bias, linearity and stability and the precision into repeatability and reproducibility. There are a number of procedures which are used, in the automotive and other industries to assess these statis

Abstract (sommario):

To analyze the metrological characteristics of measuring instruments, it was proposed to expand the conversion equation into a Taylor series. The components of this series yield equations that describe the instrument’s sensitivity as well as its additive and multiplicative errors. Additionally, a mathematical model is introduced, allowing the conversion of these additive and multiplicative errors into measurement uncertainty. The proposed models were tested using a measurement model for ion concentration based on ion-selective electrodes. The measurement accuracy assessment methodology demonst

Abstract (sommario):

Analysis of error in measuring electric energy and maximum power within direct and half-indirect measurement system at the voltage of 0.4kV is presented in the paper. The analysis involved all the elements of the measurement system, i.e. calibration and testing of the transformer-operated and direct digital energy meters and measuring current transformers. This equipment was also used for measurements in the transformer substation aiming at error analysis at measurements made under the real conditions. The results obtained show significant negative measurement error introduced by the energy me

Abstract (sommario):

Urgency of the research. There are several types of measurement devices. Industrial practice needs simple, fast and cheap measurement system for inspection of produced parts. There is a need for system like toolmakers microscope. Target setting. Toolmakers microscope is very popular because of its simplicity, but producer often do not provide information about the errors during the measurements. Actual scientific researches and issues analysis. Toolmakers microscope uses two methods of measurements – micrometer head slides in two axes XY and CCD camera for measurements of very small dimensions
