Abstract:

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:

Abstract This study presents test measurements on a Lexsyg luminescence reader, acquired by the Giessen luminescence group. The reader is of the type Standard, hence designed for routine determination of palaeodoses using quartz or K-feldspars. The tests include measurements of the stimulation powers, preheat temperatures, OSL- and TL-curves, as well as dose recovery tests and calibration measurements using highly sensitised calibration quartz. A comparison of D e values determined using a Lexsyg reader with single grain D e-values, which have been previously obtained on a Risø reader, is also presented. The results imply that the Lexsyg reader is a highly reliable measurement device with high reproducibility, yielding instrumental uncertainties of around 0.3%.

Abstract:

Abstract Kite testing by flying in a horizontal circle, was developed in order to address the inevitable accuracy problems inherent in pre-existing kite measurement techniques. However the raw results from this circular flight method are not directly comparable with traditional kite performance measurements. To enable direct comparisons to be made, modifying equations have been developed to convert the raw circular flight results into the traditional measurements of lift to drag ratio, and lift coefficient. This paper derives the modifying equations, and presents experimental results comparing traditional measurements with both the raw and modified circular flight results. The modifying equations are applied to an example set of results to assess the sensitivity of the test environment parameters. It is concluded that for many cases, the discrepancy between the raw circular flight test results and traditional measurement techniques is small enough to ignore. Alternatively, the modifying equations given in the paper may readily be encoded so that traditional results may be quickly obtained from this novel test method.

Abstract:

AbstractThe paper presents several approaches to gauge repeatability and reproducibility (GRR) analysis regarding non-replicable measurements. Measurement systems have to deal with processes in which, by the nature of the measured object or by the type of measurement itself, measurements are not repeatable. In these cases, each sample unit can be measured only once. Such situations are referred as nonreplicable measurement systems. The aim of the paper is to map out the current approaches being used in GRR analysis in various cases of non-replicable tests and compare each other in order to find out the suitable use of analysis application. Approaches used are subject to critical analysis so that its review can serve a useful base for analysis of different non-replicable tests. At present, it is desirable to bring the improving actions in order to obtain the results of high quality from such kind of measurements. Since different non-replicable tests can measure a different quality characteristic, it is valuable to bring the appropriate designs for various tests. Subsequently, this review will serve an outline how to proceed in analyzing the results obtained by non-replicable tests. Specifically, GRR analysis works with two known designs named as “Crossed” and “Nested” design, which statistical software normally use. Doubtfully, crossed design is suggested to use at certain cases and nested at other specific cases. This is assessed and improving actions designed.

Abstract:

An article devoted to the development of the latest equipment for testing road structures during the diagnostics of roads both in the process of repair and construction, and in the process of operation. A measuring station for stamp tests of road structures and their layers has been developed, which unites the test equipment into a single automated complex mounted on the base car. This eliminates the need for manual labor of the operator, increases productivity and accuracy of tests, provides the ability to perform multiple loads. At the same time, any truck or road vehicle can be used to create the load. A measuring unit with special software installed on it is used for registration and processing of measurement results. The results of laboratory tests of the measuring station, which were carried out in the laboratory of the department of metrological support of measurements of geometric quantities of SE «Ukrmetrteststandard» are highlighted. The obtained results indicate that the values of measuring force, absolute error and range of measurements of the station of movement of the station meet the regulatory requirements.

Abstract:

The repeatability of dynamic strength tests was examined by calculating coefficients of variations (CV) for the forces exerted on lifting tests using the legs, torso and arms. Static strengths were also measured and compared to dynamic strengths. The CV for dynamic strengths, was in fact slightly lower than for static strengths, 9.79% vs. 10.6%. The correlations between the two types of strength measurements were large (r=.8l) and significant, indicating that along with good repeatability dynamic tests are an acceptable form of employee strength measurement.

Abstract:

The experimental test problem of the left–right polarization-dependent lifetime asymmetry is discussed. It shows that the existing experiments cannot demonstrate the lifetime asymmetry to be right or wrong after analyzing the measurements on the neutron, the muon and the tau lifetime, as well as the g-2 experiment. However, it is pointed out emphatically that the SLD and the E158 experiments, the measurements of the left–right integrated cross section asymmetry in Z boson production by e+e- collisions and by electron–electron Møller scattering, can indirectly demonstrate the lifetime asymmetry. In order to directly demonstrate the lifetime asymmetry, we propose some possible experiments on the decays of polarized muons. The precise measurement of the lifetime asymmetry could have important significance for building a muon collider, also in cosmology and astrophysics. It would provide a sensitive test of the standard model in particle physics and allow for exploration of the possible V+A interactions.

Abstract:

Abstract The paper presents the results of wind tunnel tests aimed at determining the model bottom drag in the case of rocket model tests. The balance measurement technique of the rocket model fixed in the wind tunnel test section by the rear sting was discussed. The model was equipped with the two parallel boosters. Based on the wind tunnel test of the rocket twin model the values of the bottom pressure was determined for tested Mach numbers. An algorithm of wind tunnel corrections was shown, which allowed the total drag determination in a case of the rocket active or passive rocket flight. The test results showed the necessity of the bottom drag measurements in wind tunnel tests.

Full text

Abstract:

The hybrid design of the Pierre Auger Observatory allows for the measurement of a number of properties of extensive air showers initiated by ultra-high energy cosmic rays. By comparing these measurements to predictions from air shower simulations, it is possible to both infer the cosmic ray mass composition and test hadronic interactions beyond the energies reached by accelerators. In this paper, we will present a compilation of results of air shower measurements by the Pierre Auger Observatory which are sensitive to the properties of hadronic interactions and can be used to constrain the hadronic interaction models. The inconsistencies found between the interpretation of different observables with regard to primary composition and between their measurements and simulations show that none of the currently used hadronic interaction models can provide a proper description of air showers and, in particular, of the muon production.

Abstract:

Two force reconstruction techniques were used to evaluate the impact test of a scale model nuclear transportation cask dropped 30 ft. onto an unyielding target. The two techniques are: the sum of weighted acceleration technique (SWAT) and the deconvolution technique (DECON). A brief description and the calibration of the techniques as applied to the cask are presented. For the impact test, both techniques yielded very similar resultant forces and provided more accurate definition of the force-time history for the cask than is available from conventional data reduction methods. An applied moment, measurement previously unobtainable from conventional accelerometer data reduction techniques, was determined with SWAT. The angular velocity calculated with SWAT was verified with photometric measurements.

Abstract:

Reaction time (RT) is one of the key factors in combat sports. Its high level is a predictor of sporting success. Therefore, RT tests are an important diagnostic tool in combat sports. The implementation of some conventional psychomotor tests in virtual settings can facilitate research and improve the objectivity and standardization of the measurement procedure. The main aim of the present study was to evaluate the reliability and validity of RT measurements, using the ruler drop method (RDM) implemented within immersive virtual reality (VR). Twenty-eight professional mixed martial arts (MMA) fighters were examined. The validity of the new VR measurement method was estimated by comparing the results obtained using the computer test and the conventional catch-the-ruler test. The reliability of the measurements was evaluated using an intraclass correlation procedure. Analysis of variance was used to examine the differences in RT in MMA fighters obtained from different tests. Significant correlations were found between the results of measurements in VR and the results of other tests, with the highest values observed between the tests performed in a virtual environment and computer-based tests. The values of the ICC intraclass correlation coefficients for all the reaction time tests conducted in the group of MMA fighters were at an adequate or high level. The analysis of variance showed that the reaction time of MMA fighters differed significantly between the tests. In VR and computer-based tests, reaction times were significantly longer than during conventional RDM measurements. RT did not depend on the hand used during the test. In conclusion, the VR environment allows for designing and conducting valid reaction time tests reliably and objectively, using standard testing procedures, while reducing the effect of human factors on the measurement results.

Abstract:

AbstractAt the beginning of the year 2016, the representatives of the Polish Radon Centre decided to organize proficiency tests (PTs) for measurements of radon gas and radon decay products in the air, involving radon monitors and laboratory passive techniques. The Silesian Centre for Environmental Radioactivity of the Central Mining Institute (GIG), Katowice, became responsible for the organization of the PT exercises. The main reason to choose that location was the radon chamber in GIG with a volume of 17 m3, the biggest one in Poland. Accordingly, 13 participants from Poland plus one participant from Germany expressed their interest. The participants were invited to inform the organizers about what types of monitors and methods they would like to check during the tests. On this basis, the GIG team prepared the proposal for the schedule of exercises, such as the required level(s) of radon concentrations, the number and periods of tests, proposed potential alpha energy concentration (PAEC) levels and also the overall period of PT. The PT activity was performed between 6th and 17th June 2016. After assessment of the results, the agreement between radon monitors and other measurement methods was confirmed. In the case of PAEC monitors and methods of measurements, the results of PT exercises were consistent and confirmed the accuracy of the calibration procedures used by the participants. The results of the PAEC PTs will be published elsewhere; in this paper, only the results of radon intercomparison are described.

Abstract:

ABSTRACTWind-tunnel tests of a heavy-class helicopter model were carried out to evaluate the effectiveness of several components optimised for drag reduction by computational fluid dynamics analysis. The optimised components included different hub-cap configurations, a fairing for blade attachments and the sponsons. Moreover, the effects of vortex generators positioned on the back ramp were investigated. The optimisation effect was evaluated by comparison of the drag measurements carried out for both the original and the optimised helicopter configurations. The comprehensive experimental campaign involved the use of different measurement techniques. Indeed, pressure measurements and stereo particle image velocimetry surveys were performed to achieve a physical insight about the results of load measurements. The test activity confirms the achievement of an overall reduction of about 6% of the original model drag at cruise attitude.

Abstract:

The aim of the study was to evaluate three times repetited measurements of the beef steers temperament using of the Scale Test (1–5 score from docile to wild) and the Flight Speed Test (the time taken to cover a set distance of 1.7 m after leaving the weight scale in tenths of a second). Ten Charolais and 10 Hungarian Grey steers were used. At the start of testing, the Charolais and Hungarian Grey steers aged 446 and 487 days, respectively, while the following measurements were realized at their average age of 553 and 594 days, respectively and of 713 and 754 days, respectively. The mean temperament scores revealed that temperament was fairly consistent in Hungarian Grey steers (1.3–1.4–1.4) and it worsened in Charolais ones only on the third measurement (1.6–1.5–2.5). Flight speed varied non-significantly in Charolais (2.77–2.89–2.46 s) and in Hungarian Grey (4.09–5.01–5.33 s) steers either through the study. In our opinion, the successive use of the Scale Test and the Flight Speed Test can offer a more reliable measure of cattle temperament when the sample is small.

Abstract:

Airborne gravity measurements were made over Lake Ontario in March 1991 to establish the feasibility of using a small survey aircraft for rapid and economical gravity surveys. A LaCoste & Romberg linear dynamic gravity meter, used with a PC lap‐top based digital controller, was operated in a twin‐engine Piper Navajo aircraft. A Trimble 4000 GPS receiver, operated in differential kinematic mode with a nearby base station, provided precise navigation, and radar and barometric altimeters provided additional altitude data. A major gravity low in eastern Lake Ontario, previously outlined by underwater gravity measurements, was surveyed with six lines from two flights at an altitude of 1000 ft (300 m). Large vertical accelerations caused by aircraft motion were almost completely removed using the height measurements, although separate reductions using global positioning system (GPS) and radar heights showed significant differences that indicated that the height measurements could still be improved. A grid formed of the differences between the smoothed air data and 56 underwater stations had a mean of −0.2 mGal and standard deviation of 2.7 mGal.

Abstract:

Air pollution is still a major public health issue, which makes monitoring air quality a necessity. Mobile, low-cost air quality measurement devices can potentially deliver more coherent data for a region or municipality than stationary measurement stations are capable of due to their improved spatial coverage. In this study, air quality measurements obtained during field tests of our low-cost air quality sensor node (sensor-box) are presented and compared to measurements from the regional air quality monitoring network. The sensor-box can acquire geo-tagged measurements of several important pollutants, as well as other environmental quantities such as light and sound. The field test consists of sensor-boxes mounted on utility vehicles operated by municipalities located in Central Switzerland. Validation is performed against a measurement station that is part of the air quality monitoring network of Central Switzerland. Often not discussed in similar studies, this study tests and discusses several data filtering methods for the removal of outliers and unfeasible values prior to further analysis. The results show a coherent measurement pattern during the field tests and good agreement to the reference station during the side-by-side validation test.

Abstract:

Measurements of parity violation in nuclei can determine properties of the basic weak nucleon–nucleon interaction, thereby testing electroweak theory and quark models of nucleons. Experiments observing parity violation in the photodisintegration of deuterium, in the scattering of protons from hydrogen, and in the emission of circularly polarized γ rays from 18F are described. A new technique for polarizing 3He is described, and the use of polarized 3He in measurements of parity and time reversal violation is presented. Finally, new directions in γ-ray spectroscopy are illustrated by the Sudbury Neutrino Observatory and new ultrahigh resolution bolometric detectors.
