Abstract:

Using virtual instrument technology, digital signal processing technology and traditional optical radiation measuring technology to construct optical radiation measuring system breaks the construction methods of traditional instruments. Signal processing, collection, control and process of measuring system are implemented by the software LabVIEW8.2. And they are integrated in a computer. The computer not only is data processing center, but also is instrument control center. While measuring, the user uses the mouse to operate the handles including knobs, switch and buttons of virtual instrument panel to select instrument functions and set various parameters, which realizes measuring optical radiation with different wave bands and different intensity. And the user can change instrument operation panel, modify system software, transform instrument function, and customize instrument parameters, which embodies the idea that the software is the instrument.

Abstract:

To assure the metrological traceability of a measurement, it is required to perform an analysis of the measurement uncertainty specific to the measurement task. An approach to estimate the measurement uncertainty for complex systems is the so-called virtual measuring instrument: The measuring process is simulated taking into account its influencing parameters and a statistical analysis is performed by means of Monte-Carlo calculations. We present the development of such a virtual measuring instrument for scanning electron microscopy (SEM) which allows to estimate the measurement uncertainty in compliance with GUM for dimensional measuring tasks in nano- and microsystems technology. By application of this virtual instrument, model based corrections of systematic errors are made possible and the cognition of the strength of different perturbing influences can lead to recommendations to optimize measurement instruments and methods. The virtual model programmed in MATLAB is called ‘vREM’, it includes all essential components of the measuring chain of an SEM as modules: The electron source, the electron-optical lens-system, the scan-generator, the interaction of the electrons within the object, electron detectors, simple analysis procedures and consideration of external disturbances. By adjusting parameters uncertainty contributions can be assigned to the virtual probe, the virtual specimen and the virtual detector signals.

Abstract:

AbstractThis article considers the function of twenty-two hand-colored prints of mathematical instruments in Tycho Brahe's Astronomiae instauratae mechanica (Instruments of the renewed astronomy; 1598), a hand-painted presentation treatise dedicated to Emperor Rudolf II and conferred on a network of individuals connected to the imperial court in Prague. Although the accompanying text communicates the instruments’ use and composition, the images demand close inspection because they articulate Brahe's observationally driven astronomy. They do so through structured, repeated, and consecutive representations; through expanded viewer access, achieved by adhering to multiple perspectives; through the juxtaposition of colors, which focuses attention on the heads of the instruments (the part that does the measuring); and through the use of gold paint, which emphasizes the head and brings to mind the very metallic nature of the instruments. Much like an astronomer taking multiple measurements of cosmological phenomena, these images allow viewers and readers, as they leaf through the pages of the treatise, to become virtual participants in Brahe's instauration of astronomy.

Abstract:

<p class="Abstract">In the age of the Internet of Things and Industry 4.0, more and more embedded systems are connected through open networks, which also concerns measuring instruments under legal control (e.g. smart meters). Therefore, cyber-security for measuring instruments is becoming increasingly important. In this paper, possibilities to design secure measuring software running on general-purpose operating systems are analyzed according to legal requirements set up by European Directives, e.g., the Measuring Instruments Directive (2014/32/EU), which define the mandatory security level. Technical interpretations for the security concepts described in this paper are derived from these legal requirements with the aim to provide manufacturers the architectural guidance to construct systems which easily pass a conformity assessment at a Notified Body. In this paper security concepts, i.e., SELinux, AppArmor and Mandatory Integrity Control (MIC) are being described, which are based on Mandatory Access Control (MAC) strategies. Additionally, high-security methodologies and concepts, e.g., MILS and security kernels, are highlighted. In the examples given, software separation, which enhances overall security, is achieved by using SELinux mechanisms in the modules (virtual machines) atop a separation kernel.</p>

Abstract:

Modern graduates need to work with electronic devices. On laboratory work, students conduct experiments to solve practical problems of researching real problems that arise in the design and operation of electronic devices. However, the shortage of laboratory equipment and assistants for maintenance and assistance in work, its high cost reduce the quality of laboratory work. On the other hand, modern education is increasingly using a network resource. Virtual laboratories have their advantages, but even when carrying out a physical experiment in them, the sense of the reality of what is happening disappears. Effective solutions to the effectiveness and quality of conducting laboratory exercises can be found using a system of virtual instruments that can be accessed via the Internet or directly at the university.The aim of the research is to show, by the example of one experimental device made on the National Instruments ELVIS platform, the advantages of a combined approach to learning – a successful combination of a virtual resource and a real physical experiment. The laboratory model described in the article is very practical for studying radio-engineering devices, and it can ideologically serve as a basis for other similar developments.The research was based on the prototype board for studying the basics of analog electronics for the NI ELVIS workstation, the cycle of laboratory work on the general technical discipline “Electronics”, the results of their protection, and the results of intermediate student controls. In work the following methods are used: laboratory experiment, modeling, pedagogical testing. The results of the research show that students feel the need for more knowledge about real processes and systems. This need is most evident in the direction of the preparation of bachelors of engineering and technology. They expect from a laboratory work a real physical experiment, but with the convenience of computer-processing results. A new paradigm for studying radio electronic devices, based on physical experiments in a virtual instrument system gives an improvement in the quality of instruction and allows students to study the circuitry of analog devices more effectively. The ideology of virtual instruments leads to more motivation for students; they gain skills to work with modern measuring equipment and at the same time communication skills in a group, as the computer resource is used as a research tool, not the purpose of learning.A physical experiment, using virtual measuring instruments, accessibility and mobility of laboratory facilities, additional motivation of students are the main advantages of using the NI ELVIS hardware and software platform with a specialized breadboard model in the educational process.

Abstract:

The importance of water quality management in pipes has been recently highlighted through the "Red-water phenomenon" in the city of Incheon. This study proposed a methodology for determining the location of measuring instruments during abnormal water quality issues. The proposed method focuses on analyzing the sensitivity of the flow path through a pipe. Additionally, this flow sensitivity through the tube is analyzed by considering both normal and abnormal conditions. The sensitivity of a pipe is the rate at which the water-flow direction changes. Further, a tube with low sensitivity under normal conditions but high sensitivity under abnormal conditions is the pipe for which the instrument should be first installed. The results were analyzed by applying the proposed methodology to a conventional virtual network. It is expected that, in future, the proposed method for determining the location of water quality gauges could be a useful tool for determining the location of instruments during emergencies.

Abstract:

Virtual and concrete models have been of interest in chemistry teaching to improve students’ understanding of a three-dimensional representation of chemical concepts such as symmetry. This study aims to determine the effectiveness of using concrete and virtual models on students’ understanding of symmetry. Students’ understanding was also explored in light of their spatial ability. The study was conducted using a quasi-experimental design with 62 students as participants. Two different instruments, spatial ability and understanding of symmetry tests, were employed for data collection. Data analysis was performed using the Pearson product-moment correlation and two-way variance analysis test. The results showed the virtual model’s contribution to improving students’ understanding of symmetry is higher than that of the concrete model for both students with high spatial ability (HSA) and low spatial ability (LSA). Also, the better students’ spatial ability, the better their understanding of molecular symmetry.

Abstract:

At the present stage of development of digital information technologies intensive digitalization (computerization) of both direct and indirect measurement methods is taking place. The direct consequence of the computerization of measurements was, firstly, the emergence of a new class of measuring instruments – Processor measuring instruments (PRIS), secondly, increasing the level of formalization of measuring procedures, thirdly, the creation of a new, revolutionary technology –Virtual Instrument (VI). The purpose of the article is to analyze the development of digital technologies for measuring spectra, identifying the problems that arise in this case and formulating priority scientific and applied problems for their resolution.Theoretical and applied research has established that digital spectrum measurement technologies, in addition to significant advantages, have certain disadvantages. It has been shown that the disadvantages of digital technologies for measuring spectra arise both from the nature of digital methods and from the analytical and stochastic properties of the bases of the applied transformations in measuring the spectra. An analysis of digital methods for measuring spectra showed that methods based on Discrete Fourier Transform (DFT) retain their leading role and are effective in almost all subject areas. However, there are also problems of digitalization of measurements of the spectra of signals based on the DFT, which are associated, first of all, with the manifestation of a number of negative effects that are absent with analog methods for measuring spectra based on the Fourier transform. This is the periodization effect of the measuring signal and its spectrum, the stockade effect, as well as the aliasing effect. As the analysis showed, existing methods of dealing with the negative effects of digitalization of spectrum measurements solve the problems of introducing digital technologies only partially. To combat the negative effects of digitalization of spectral measurements, a generalization of the DFT in the form of a parametric DFT (DFT-P) (Parametric Discrete Fourier Transform – DFT-P) is proposed.The main scientific and applied problems of computerization of signal spectrum measurements are formulated: the development of the theory of digital methods for measuring signal spectra, the creation of new and improvement of existing digital methods for measuring signal spectra, the development of algorithmic, software and metrological software for PRIS and VI for the implementation of DFT-P.

Abstract:

Two methods for assessing situation awareness (SA) were field tested during infantry exercises. Eight platoons of U.S. Military Academy cadets executed an infantry mission during summer field training exercises. A subjective SA measure, the Mission Awareness Rating Scale (MARS), was given to each platoon leader and one squad leader from each platoon to self-assess both SA and cognitive workload demanded by the tasks. In addition, infantry expert observers rated each platoon and squad leader using the Situation Awareness Behaviorally Anchored Rating Scale (SABARS). Both MARS and SABARS had been validated previously in missions conducted in a virtual environment. In the current field test, both instruments showed evidence of successfully measuring SA. Both instruments show promise for assessing SA in the field, or in other venues where more obtrusive measurement protocols are undesirable.

Abstract:

Virtual sensing is crucial in order to provide feasible and economical alternatives when physical measuring instruments are not available. Developing model-based virtual sensors to calculate real-time information at each targeted location is a complex endeavor in terms of sensing technology. This paper proposes a new approach for model-based virtual sensor development using computational fluid dynamics (CFD) and control. Its main objective is to develop a three-dimensional (3D) real-time simulator using virtual sensors to monitor the temperature in a greenhouse. To conduct this study, a small-scale greenhouse was designed, modeled, and fabricated. The controller was based on the convection heat transfer equation under specific assumptions and conditions. To determine the temperature distribution in the greenhouse, a CFD analysis was conducted. Only one well-calibrated and controlled physical sensor (temperature reference) was enough for the CFD analysis. After processing the result that was obtained from the real sensor output, each virtual sensor had learned the associative transfer function that estimated the output from given input data, resulting in a 3D real-time simulator. This study has demonstrated, for the first time, that CFD analysis and a control strategy can be combined to obtain system models for monitoring the temperature in greenhouses. These findings suggest that, generally, virtual sensing can be applied in large greenhouses for monitoring the temperature using a 3D real-time simulator.

Abstract:

145 Background: ASCO recommends “…combined standard oncology and palliative care…early in the course of illness for any patient with metastatic cancer and/or high symptom burden”. Few settings have implemented this recommendation and rural community cancer centers (CCC) are particularly disadvantaged due to scarce palliative care (PC) resources. The evidenced-based ENABLE (Educate, Nurture, Advise, Before Life Ends) early concurrent PC intervention has demonstrated efficacy and benefit for rural patients and caregivers and we are implementing ENABLE using a virtual learning collaborative funded by the American Cancer Society. Since no PC-specific implementation measures exist, one of our primary efforts has been instrument development. Methods: This Implementation Study includes 4 racially-diverse CCCs: Gibbs Cancer Center, Spartanburg, SC; Mitchell Cancer Institute, Mobile, AL; Birmingham VAMC; and Gyn Oncology/University of Alabama at Birmingham. The project aims are to: 1. Build an interactive research community to assess sites’ institutional structure and PC resources; and 2. Evaluate pre- and post-ENABLE implementation using RE-AIM (Reach, Effectiveness, Adoption, Implementation, and Maintenance) framework. An expert panel assisted with implementation measure development specific to ENABLE’s essential elements. Instruments include: the General Organizational Index, the RE-AIM Assessment Tool, Oncology Providers Perceptions of Early Concurrent PC, and Implementation Costs. Results: All measures were found to have face and content validity. Feasibility and inter-rater reliability were determined during pilot-testing. Data, (housed in a REDCap database), have been collected using face-to-face interviews and web-based platforms over 2 cycles of pre- and post-implementation site visits. Measurement challenges include: 1. Inconsistent IRB interpretation of implementation science practices; 2. Limited implementation resources (space, staff, and time); and 3. Difficulties with centralized data collection. Conclusions: Valid measures are critical to determine implementation success. We will present implementation measures (Toolkit) and examples of outcome data.

Abstract:

Digital three-dimensional models of the existing architectonic structures are created for the purpose of digitalization of the archive documents, presentation of buildings or an urban entity or for conducting various analyses and tests. Traditional methods for the creation of 3D models of the existing buildings assume manual measuring of their dimensions, using the photogrammetry method or laser scanning. Such approaches require considerable time spent in data acquisition or application of specific instruments and equipment. The goal of this paper is presentation of the procedure for the creation of 3D models of the existing structures using the globally available web resources and free software packages on standard PCs. This shortens the time of the production of a digital three-dimensional model of the structure considerably and excludes the physical presence at the location. In addition, precision of this method was tested and compared with the results acquired in a previous research.

Abstract:

The student experience with different aspects of online instructional settings has been the focus of educational practitioners and researchers in many studies. However, concerning technology-enabled formative assessment, little is known about student satisfaction regarding different possible formative e-assessment strategies the students are involved in. Using a 5-point Likert scale questionnaire, a web-based survey was developed to examine students’ satisfaction with the formative e-assessment strategies within an enriched virtual blended course. The results show that, in general, the students were satisfied with the quality of their engagement and the quality of feedback across all the formative e-assessment activities offered. The results also show that the student satisfaction varied between and within the formative e-assessment strategies. However, the gap between the student satisfaction mean ratings across all formative e-assessment strategies was marginal and could not help researchers decide upon which formative e-assessment strategy that stood out as the most preferred one. Learner satisfaction with different formative e-assessment strategies was positively correlated to each other at various levels but no relationship was found between students’ scores on the final course exam and learner satisfaction with formative e-assessment strategies. In the end, the results indicated that a sustained and integrated use of the all three formative e-assessment strategies (online knowledge survey, online student-generated questions and peer-responses, and electronic reflective journals) should be used in the context of hybrid courses. The study also suggests further studies that would widen, diversify both the scope and research instruments to investigate learner satisfaction with formative e-assessment strategies.

Abstract:

The purpose of the research was to analyze the existing systems for measuring forces during machining of parts on metal-cutting machine tools, and to consider the options for using both specialized ready-made solutions and dynamometer heads of the UDM series as measuring transducers. The study shows the drawbacks of the well-known general-circuit solutions for the modernization of these dynamometers, associated with the need to use heterogeneous sets of amplifying and transforming equipment. We propose low-budget solutions to improve the accuracy and reliability of measurements, to control and record measurement results in a modern software environment using virtual instruments. As a result of the study, we implemented hardware and software methods for processing measurement information, accompanying experimental studies in real time. The universal scalable systems developed for measuring moments and cutting forces are used both during academic research work and educational process of the university The work is carried out under the program "Scientific and scientific-pedagogical personnel of innovative Russia", event: 1.2.1.

Abstract:

One of the technologies that people are starting to get interested in is virtual reality (VR). VR is widely used as a means of entertainment, even more so at this time, the e-sports industry is developing rapidly. However, the use of VR can cause cybersickness, a disease arising from sensory and perceptual mismatches between the visual and vestibular systems. The emergence of cybersickness can be related to gender and experience using VR. There have been studies on cybersickness, but the results obtained had not come to the same conclusion. This research aims to identify the effect of gender and experience using VR, predict the timing of cybersickness by using physiological measurements, and provide recommendations that can minimize cybersickness in activities using VR. The measuring instruments used are the galvanic skin response (GSR) and a simulator sickness questionnaire (SSQ). In this study, the influence test is conducted by using ANOVA and Kruskal-Wallis to determine whether gender and experience using VR affect the potential for cybersickness. Based on the GSR measurement results, it found that gender and experiences of using VR do not affect a person's potential for cybersickness. From the result of SSQ measurement, gender does not affect the cybersickness, but the experience of using VR affected a person's potential for cybersickness. Qualitatively, cybersickness symptoms appear in the 15-20 minutes after the VR game has set in. Therefore, it is recommended to limit the usage of VR to less than 15 to 20 minutes per session. Keywords: cybersickness, galvanic skin response (GSR), simulator sickness questionnaire (SSQ), virtual reality

Abstract:

Risk stratification to assess healthcare outcomes among older people is challenging due to the interplay of multiple syndromes and conditions. Different short risk-screening tools can assist but the most useful instruments to predict responses and outcomes following interventions are unknown. We examined the relationship between a suite of screening tools and risk of adverse outcomes (pre-determined clinical ‘decline’ i.e., becoming ‘unstable’ or ‘deteriorating’ at 60–90 days, and institutionalisation, hospitalisation and death at 120 days), among community dwellers (n = 88) after admission to a single-centre, Irish, Community Virtual Ward (CVW). The mean age of patients was 82.8 (±6.4) years. Most were severely frail, with mean Clinical Frailty Scale (CFS) scores of 6.8 ± 1.33. Several instruments were useful in predicting ‘decline’ and other healthcare outcomes. After adjustment for age and gender, higher frailty levels, odds ratio (OR) 3.29, (p = 0.002), impaired cognition (Mini Mental State Examination; OR 4.23, p < 0.001), lower mobility (modified FIM) (OR 3.08, p < 0.001) and reduced functional level (Barthel Index; OR 6.39, p < 0.001) were significantly associated with clinical ‘decline’ at 90 days. Prolonged (>30 s) TUG times (OR 1.27, p = 0.023) and higher CFS scores (OR 2.29, p = 0.045) were associated with institutionalisation. Only TUG scores were associated with hospitalisation and only CFS, MMSE and Barthel scores at baseline were associated with mortality. Utilisation of a multidimensional suite of risk-screening tools across a range of domains measuring frailty, mobility and cognition can help predict clinical ‘decline’ for an already frail older population. Their association with other outcomes was less useful. A better understanding of the utility of these instruments in vulnerable populations will provide a framework to inform the impact of interventions and assist in decision-making and anticipatory care planning for older patients in CVW models.

ObjectivesTo describe critical features of the Ethiopian Pediatric Society (EPS) Quality Improvement (QI) Initiative and to present formative research on mentor models.SettingGeneral and referral hospitals in the Addis Ababa area of Ethiopia.ParticipantsEighteen hospitals selected for proximity to the EPS headquarters, prior participation in a recent newborn care training cascade and minimal experience with QI.InterventionsEducation in QI in a 2-hour workshop setting followed by implementation of a facility-based QI project with the support of virtual mentorship or in-person mentorship.Primary and secondary outcome measuresPrimary outcome—QI progress, measured using an adapted Institute for Healthcare Improvement Scale; secondary outcome—contextual factors affecting QI success as measured by the Model for Understanding Success in Quality.ResultsThe dose and nature of mentoring encounters differed based on a virtual versus in-person mentoring approach. All QI teams conducted at least one large-scale change. Education of staff was the most common change implemented in both groups. We did not identify contextual factors that predicted greater QI progress.ConclusionsThe EPS QI Initiative demonstrates that education in QI paired with external mentorship can support implementation of QI in low-resource settings. This pragmatic approach to facility-based QI may be a scalable strategy for improving newborn care and outcomes. Further research is needed on the most appropriate instruments for measuring contextual factors in low/middle-income country settings.

Abstract:

The paper shows the relevance of studying the mechanical properties of biological tissues and biocompatible materials for solving the problems of general and reconstructive surgery, transplantology, manual therapy, virtual simulation of surgical operations, robotic surgery, etc. The authors present basic information about biological tissue as an object of research and give a brief overview of the devices used for studying the mechanical characteristics of biological tissues. An experimental system for testing deformations of biological tissues and biocompatible materials during compression is described. The system is developed using modern hardware and software, as well as effective technical solutions. The results of the practical use of the developed device are presented and the obtained dependences of the mechanical stress of biological tissue samples on their deformation under pressure are analyzed. The system has high metrological characteristics and low cost, and allows performing all the necessary functions for measuring, processing and visualizing the data. The measurements obtained with this system can help form the recommendations for doctors on choosing the optimal operation mode of medical devices and instruments in each specific case. In addition, the measured data can be used to create mathematical models of biological tissues and biocompatible materials in order to further carry out virtual experiments. In further studies, the authors plan to create the mathematical models of biological tissues based on the finite element method and using the actual values characterizing the tissue, obtained with the developed system.

Abstract:

Background:Hip and knee OA is characterised by disease flares – understanding the determinants and consequences of OA flares has been hampered by lack of a standardized flare measure beyond the pain aspect. The patients point of view on the different aspect of their flares is essential.Objectives:The objective was to assess the psychometric properties of a new questionnaire for measuring the multidimensional aspect of flares in OA.Methods:Using a bilingual version of the questionnaire (33 items, response on a numeric scale, from 0 to 10), a multicentre survey (Australia, France and United States) was conducted on line with patients diagnosed with OA of the hip and/or the knee. Based on an international OMERACT/OARSI endorsed definition of the five core domains (pain, swelling, stiffness, consequences of symptoms and psychological aspects) composing a flare in OA [1], a confirmatory factorial analysis linked to the content analysis has been used to reduce the number of items and to determine the validity of the structure. The Flare-OA questionnaire (score from 0 to 100) has been tested in French and English for its internal consistency, its convergent validity with HOOS/KOOS and Mini-OAKHQOL questionnaires, and its discriminant validity.Results:Out of 398 patients (mean age 64 years old) who completed the questionnaire, 70.4% were female and 86.7% had knee OA. The confirmatory factorial analysis retained a model with 19 items (RMSEA =0.06; SRMR =0.04; CFI =0.96 and TLI = 0.94). The Cronbach Alpha was > 0.9 for the 5 domains and for the whole questionnaire. The correlations between the Flare-OA and the other instruments were in line with that hypothesis flare is related but different from other concepts usually measured. The discriminant validity was evidenced by a significant score difference (31.8; p<0,0001) between patients with and without flare, i.e. over twice the standard measurement error.Conclusion:The optimized Flare-OA questionnaire (19 items) is a reliable and valid instrument freely available from the authors for measuring the frequency and severity of flare in knee and hip OA in clinical research.References:[1]King LK, Epstein J, Cross M, et al.

Abstract:

SummaryObjectives: 1) To enhance the content of an ontology for designing virtual environments (VEs) for upper limb motor rehabilitation of stroke patients according to the suggestions and comments of rehabilitation specialists and software developers, 2) to characterize the perceived importance level of the ontology, 3) to determine the perceived usefulness of the ontology, and 4) to identify the safety characteristics of the ontology for VEs design according to the rehabilitation specialists.Methods: Using two semi-structured Web questionnaires, we asked six rehabilitation specialists and six software developers to provide us with their perception regarding the level of importance and the usability of the ontology. From their responses we have identified themes related to perceived and required safety characteristics of the ontology.Results: Significant differences in the importance level were obtained for the Stroke Disability, VE Configuration, Outcome Measures, and Safety Calibration classes, which were perceived as highly important by rehabilitation specialists. Regarding usability, the ontology was perceived by both groups with high usefulness, ease of use, learnability and intention of use. Concerning the thematic analysis of recommendations, eight topics for safety characteristics of the ontology were identified: adjustment of therapy strategies; selection and delimitation of movements; selection and proper calibration of the interaction device; proper selection of measuring instruments; gradual modification of the difficulty of the exercise; adaptability and variability of therapy exercises; feedback according to the capabilities of the patient; and real-time support for exercise training.Conclusions: The rehabilitation specialists and software developers confirmed the importance of the information contained in the ontology regarding motor rehabilitation of the upper limb. Their recommendations highlight the safety features and the advantages of the ontology as a guide for the effective design of VEs.

Abstract:

AbstractValidity and correctness test verification of the measuring software has been a thorny issue hindering the development of Gear Measuring Instrument (GMI). The main reason is that the software itself is difficult to separate from the rest of the measurement system for independent evaluation. This paper presents a Virtual Gear Measuring Instrument (VGMI) to independently validate the measuring software. The triangular patch model with accurately controlled precision was taken as the virtual workpiece and a universal collision detection model was established. The whole process simulation of workpiece measurement is implemented by VGMI replacing GMI and the measuring software is tested in the proposed virtual environment. Taking involute profile measurement procedure as an example, the validity of the software is evaluated based on the simulation results; meanwhile, experiments using the same measuring software are carried out on the involute master in a GMI. The experiment results indicate a consistency of tooth profile deviation and calibration results, thus verifying the accuracy of gear measuring system which includes the measurement procedures. It is shown that the VGMI presented can be applied in the validation of measuring software, providing a new ideal platform for testing of complex workpiece-measuring software without calibrated artifacts.

Abstract:

Elastic modulus is one of the most important performance parameters of wood-based material, and plays an important role for predicting and evaluating quality of wood-based material. At present, the traditional problems for measuring elastic modulus of wood-based material are: expensive testing instrument, short precision, low immunity to noise and less ease to connect. This paper presents a new elastic modulus-measuring system based on virtual instrument. The system ensures the following functions: (1) real-time data acquisition, (2) signal processing and analyze, (3) saving the file in the appropriate format, (4) computing dynamic elastic modulus by the natural frequency. The analytical results of our experiments show that it is feasible, reliable and effective to use the proposed instrumentation for measuring elastic modulus of wood-based floor.

Abstract:

During quantitative analysis on measured object by using equal precision measurement method, there remains certain difference between the measuring result and truth value due to the impact on measuring method, measuring tools and measuring environment. In order to reduce measurement error, we usually make continuous equal precision measurements on the measured object repeatedly. Then we get the final result by theoretical calculations, error analysis and dispose on measurement data. The data processing shows complicated and error-prone .But now we take computer as a carrier, then combining with virtual instrument technology to accomplish the data-processing system. It can cover the manual computation shortage and can take humanization disposal on measurement data. Moreover, the results can show with multi-mode intuitively.
