In this study, we present the first iteration of DPower, an energy conserving method for use in underwater acoustic networks. The method encompasses a straightforward transmission power calibration procedure and adaptive power level selection. The method was evaluated in combination with DFlood, a known and validated constrained flooding protocol developed for underwater applications. Simulations of a network with given prerequisites have shown that, with an acceptable increase in packet loss, the presented method can dramatically reduce the energy consumption and thus improve the life-time of networks., Part of proceedings: ISBN 978-1-7281-9315-1QC 20220816

Transradijalna amputacija je dramatičan događaj koji rezultuje trajnim gubitkom motornih i senzorskih funkcija šake. Primenom mioelektričnih proteza moguće je u određenoj meri nadoknaditi izgubljene motorne funkcije. Iako su danas komercijalno dostupne različite multifunkcionalne proteze, veliki broj pacijenata ne koristi mioelektrične proteze, a kao jedan od glavnih nedostataka navode izostanak senzorskih povratnih informacija sa proteze. Zatvaranje povratne sprege bi direktno uticalo na poboljšanje kvaliteta mioelektrične kontrole i u velikoj meri omogućilo korisniku da oseća i prihvati mehanički sistem kao deo svog tela. Jedan od mogućih pristupa ovom problemu je senzorska supstitucija, odnosno prikupljanje relevantnih informacija sa proteze i njihovo prenošenje korisniku aktiviranjem preostalih senzorskih struktura. Često korišćena neinvazivna metoda supstitucije jeste električna stimulacija povorkama strujnih impulsa malih amplituda, kojima se preko površinskih elektroda aktiviraju aferentni nervi u ostatku podlaktice. Modulacijom parametara stimulacije (npr. amplituda, frekvencija, impulsna širina) je moguće aktivirati različite senzorske receptore u koži koji rezultuju osećajima različitog kvaliteta i jačine, i na taj način preneti informacije sa proteze. Povratne informacije se mogu preneti korisniku i promenom lokacije stimulusa, odnosno prostornom modulacijom, koja zahteva primenu višekanalnog interfejsa..., Transradial hand amputation is a dramatic event that results in permanent loss of motor and sensory functions. Myoelectric prostheses can be used to restore the missing motor functions to a certain degree. Although there are numerous commercially available multifunctional prostheses, many patients reject myoelectric prostheses, and state that one of major drawbacks is the lack of sensory feedback from the prosthesis. Closing the loop would directly improve the quality of myoelectric control, but also help users to feel and accept the mechanical system as part of their own body. One approach to this problem is sensory substitution, based on gathering relevant information from the prothesis and transmitting it to the user by activating the remaining sensory structures. Commonly used non-invasive substitution method is electrical stimulation with small amplitude current pulses, which activate afferent nerves in the remaining of the forearm via surface electrodes. Through the modulation of stimulation parameters (e.g. amplitude, frequency, pulse width), sensations of different quality and intensity can be elicited by activating different sensory receptors in the skin, thus transmitting the information from the prosthesis. Feedback can also be provided to the user by changing the location of the stimulus (spatial modulation) which requires the use of a multi-channel interface...

A vessel's response to waves is dependent on a large number of parameters, some of which are both frequency and direction dependent. To predict vessel response, these parameters are used to construct response amplitude operators (RAOs) that act as transfer functions between the directional wave spectra and the motion spectra of the vessel. In particular situations, however, vessel motions predicted using RAOs calculated with general-purpose radiation-diffraction codes and measured wave spectra are found to deviate from measured vessel responses. To address this problem, a methodology for calibrating RAOs based on measurements of the directional wave spectra and vessel motions is proposed. Use is made of a vector fitting method through which the frequency dependent hydrodynamic properties of the vessel can be approximated by a ratio of two polynomials, thus greatly reducing the number of parameters that need to be calibrated. The reduced set of parameters is subsequently related to previously identified causes of RAO inaccuracy in order to arrive at optimization algorithms for identifying more accurate RAOs from the measurements. It is shown that the RAOs can be improved with accuracy in situations where the discrepancies are caused by imprecise estimates for the vessel's radii of gyration, center of gravity, or viscous damping. When the discrepancies in the RAOs are related to the potential mass, damping and wave forces, however, the problem becomes highly non-convex and it is not possible to find a unique RAO that satisfies the data., Accepted Author Manuscript, Dynamics of Structures, Offshore Engineering

This work proposes a calibration procedure to obtain the material parameters required by the Serial/Parallel Mixing Theory for the analysis of composites. A set of experimental tests are defined to obtain the main composite failure modes. Then, it is proposed to calculate the parameters required by the formulation using the experimental results. The procedure proposed is validated by comparing the numerical results, with those obtained from the experimental campaign. This comparison shows that the Serial/Parallel mixing theory is capable of representing the failure modes of the composite for different loading scenarios as well as the material toughness., Postprint (published version)

This project has five specific objectives: To provide traceability for dynamic pressure and temperature through development of measurement standards and validated calibration procedures; To quantify the effects of influencing quantities on the response of dynamic pressure and temperature sensors, in order to determine the appropriate calibration procedures and measurement uncertainties for industrial measurements; To develop new measurement methods and sensors for measuring dynamic pressure and temperature in demanding industrial applications, and to demonstrate the improved accuracy and reliability obtained with those; To validate all of the methods and sensors developed in this project through demonstrations in selected industrial applications; and To ensure by close engagement with industry, that the developed calibration and measurement techniques and technology are adopted by them. The challenge is that in many industrial applications pressure and temperature measurements are performed under dynamically changing conditions. The aim of this project is to improve the accuracy and reliability of pressure and temperature measurements in these challenging conditions.

The laser ranging interferometer (LRI) on board of the GRACE follow-on spacecraft, launched in May 2018, is the first laser interferometer to perform an inter-satellite range measurement. It is designed for ranging noise levels of 80 nm Hz−1/2 for frequencies above 20 mHz, i.e., about a ten-fold improvement with respect to the GRACE follow-on main microwave ranging instrument. One of the most critical steps during the commissioning phase of the instrument is the so-called initial line of sight calibration procedure (or initial acquisition). This process is required to quantify large uncertainties with respect to laser beam pointing angles and laser frequency, which must be known to establish the interferometer link. It is a nine hour scan of five degrees of freedom, which all need to match simultaneously at least once. Here we report on laboratory tests to further validate the calibration procedure using a mock-up LRI and a set-up, the so-called laser link simulator, that creates conditions similar to those with ~220 km distance between the SC. The experiments presented here made use of LRI-like hardware and software and were carried out recreating critical conditions such as received laser powers on the pico-Watt level and their dependence on the SC misalignments, flat-top beams as receiving beams and Doppler frequency shifts. Several configurations were tested, including a full line of sight calibration with angular scans in both mock-up SC and frequency scan in one of the lasers. Results are well in agreement with the expectations and confirm, well before the LRI commissioning phase, the robustness of the procedure under realistic conditions, which had not yet been fully tested experimentally.

Метрологическое обеспечение – важная составляющая деятельности предприятия. Основными процедурами являются поверка и калибровка средств измерений. Согласно действующей на сегодняшний день нормативной документации, для калибровки следует применять такой термин как неопределенность. При использовании неопределенности возникают трудности, в том числе при написании методик калибровки, Metrological supervision is an important component of the enterprise's activities. The main procedures are verification and calibration of measuring instruments. According to the current regulatory documentation, a term such as uncertainty should be used for calibration. When using uncer-tainty, difficulties arise, including when writing calibration procedures

An established method for precise determination of optical absorption is the so called laser calorimetry. According to ISO 115511 laser calorimetry is preferred to other photothermal test methods, because of its capability to deliver absolute calibration. Many optical materials have low heat conductivity, which can affect the calibration significantly. The timeand spatial dependent temperature profile in a sample of materials with low heat conductivity requires accurate temperature measurement strategies to determine material-independent and absolutely calibrated absorption values. For thin cylindrical samples, ISO 11551 provides a strategy to compensate heat conductivity effects. The optimal temperature sensor position, where accordingly calibrated measurement results2 can be obtained, is simply based on the symmetric sample geometry. For thick geometries an additional temperature distribution along propagation direction of the heating beam must be considered. The current version of ISO 11551 does not provide a sophisticated solution for this problem, because the heating scheme of a sample is usually unknown. Therefore, a reliable calibration procedure can only be applied to samples of well-known absorption properties of surfaces and bulk material. Utilizing such kind of specifically prepared reference samples in combination with Finite Element Method (FEM) calculations, a general measurement and data evaluation concept based on laser calorimetry is presented, that allows deriving absolutely calibrated absorption measurement results for rectangular sample geometries. © 2017 SPIE.

We propose an integrated model of the joint dynamics of FX rates and asset prices for the pricing of FX derivatives, including Quanto products; the model is based on a multivariate construction for Lévy processes which proves to be analytically tractable. The approach allows for simultaneous calibration to market volatility surfaces of currency triangles, and also gives access to market consistent information on dependence between the relevant variables. A successful joint calibration to real market data is presented for the particular case of the Variance Gamma process., SCOPUS: ar.j, info:eu-repo/semantics/published

Comprehensive models are widely adopted to predict the performance of compressors due to their low computational cost and acceptable prediction capability. In general, the accuracy of such models depends strongly on the correct adjustment of some parameters that are of difficult to determine both analytically and experimentally. However, due to the nonlinearities of the compressor model, the tuning of such parameters affects many output variables and hence can be very challenging and time consuming. In this paper, we consider this procedure of adjustment of parameters as a multiple objective optimization problem that can be solved by using an elitist non-dominated sorting genetic algorithm (NSGA-II). The parameters of two simulation models are adjusted following this new procedure. In the first model the suction muffler was neglected and a mass-spring-damper system was adopted to predict the suction valve dynamics. The second model solves the suction valve dynamics by the finite element method and the flow in the suction muffler with the finite volume method. In both models the clearance volume and parameters associated with the suction valve were chosen to be adjusted while the deviations between predictions and measurements for the mass flow rate, indicated power, and suction valve dynamics were defined as the objective functions to be minimized.

A reliable and simple-to-use algorithm was developed for the energy-calibration of double-sided silicon strip detectors (DSSSDs). It works by enforcing mutual consistency of p-side and n-side information for every detected event. The procedure does not rely on a dedicated data set for calibration and is robust enough to work fully automated without human supervision. The method was developed and applied to data from a DSSSD of the Lund-York-Cologne CAlorimeter (LYCCA) for the HISPEC experiment at FAIR. It has been tested on ions in the A â 90 mass range at energies of E kin â 300 MeV / u .

Resonant RL shunt circuits constitute a robust approach to piezoelectric damping, where the performance with respect to damping of flexible structures requires a precise calibration of the corresponding circuit components. The balanced calibration procedure of the present paper is based on equal damping of the two modes associated with the resonant vibration form of the structure, when including a quasi-static contribution from non-resonant vibration modes via a single background flexibility parameter. Explicit calibration formulae are presented, and it is demonstrated by a numerical example that the procedure leads to equal modal damping and effective response reduction, even for rather indirect placement of the transducer, provided that the correction for background flexibility is included in the calibration procedure.

A superconducting microwave resonator is modified with several weak links to make it nonlinear and operated as a phase-insensitive microwave amplifier. Signal gain is demonstrated by intermodulation with a strong pump. The gain is sharply frequency dependent, and we demonstrate phase dependence by examining correlations between the signal and one idler which is a 3rd order intermodulation product of the pump and signal tones. A calibration procedure is described which is based on measurement of both thermal and quantum noise, revealing that the following HEMT amplifier adds noise at 15 times the quantum limit. When operated as a phase-insensitive amplifier the nonlinear resonator added noise at 2.5 times the quantum limit. Significant power is found at intermodulation products beyond 3rd order, which may be responsible for the inability to reach the quantum limit, QC 20201002

The ANTARES deep-sea neutrino telescope comprises a three-dimensional array of photomultipliers to detect the Cherenkov light induced by upgoing relativistic charged particles originating from neutrino interactions in the vicinity of the detector. The large scattering length of light in the deep sea facilitates an angular resolution of a few tenths of a degree for neutrino energies exceeding 10 TeV. In order to achieve this optimal performance, the time calibration procedures should ensure a relative time calibration between the photomultipliers at the level of ~1 ns. The methods developed to attain this level of precision are described.

In human-human communication, eye gaze is a fundamental cue in e.g. turn-taking and interaction control [Kendon 1967]. Accurate control of gaze direction is therefore crucial in many applications of animated avatars striving to simulate human interactional behaviors. One inherent complication when conveying gaze direction through a 2D display, however, is what has been referred to as the Mona Lisa effect; if the avatar is gazing towards the camera, the eyes seem to "follow" the beholder whatever vantage point he or she may assume [Boyarskaya and Hecht 2010]. This becomes especially problematic in applications where multiple persons are interacting with the avatar, and the system needs to use gaze to address a specific person. Introducing 3D structure in the facial display, e.g. projecting the avatar face on a face mask, makes the percept of the avatar's gazechange with the viewing angle, as is indeed the case with real faces. To this end, [Delaunay et al. 2010] evaluated two back-projected displays - a spherical "dome" and a face shaped mask. However, there may be many factors influencing gaze directionpercieved from a 3D facial display, so an accurate calibration procedure for gaze directionis called for., tmh_import_11_12_14.

The biggest challenge in semi-arid areas is finding ways of reducing the major unproductive water loss: evaporation from the soil surface. A large number of subsistence farmers east of Bloemfontein, in and around Thaba’Nchu in the Free State Province of South Africa occupy about 11 000 ha of land. The economic potential of this communal land still needs to be unlocked and the natural resource base is critical for this endeavour. However, the prevalence of clay and duplex soils is a major constrain towards improving food security in this area. Poor soil water regimes resulting from prolific runoff and evaporation losses is one of the reasons especially when conventional tillage is used. It was therefore hypothesized that by quantifying soil surfaces evaporation (Es); characterizing of the soil hydraulic properties and understanding the effect of temperature on mulch type and coverage of the Bonheim (Bo) soil can contribute to the improvement of the infield rainwater harvesting (IRWH) system and fill a gap in knowledge under South African conditions that is in terms of promoting water storage capacity and minimizing Es for better crop yields. The ECH2O-TE probes used in this study were calibrated to measure soil water content ( ) and temperature (T). The evaporative desorption procedure (EDP) of Van der Westhuizen (2009) for coir was modified to calibrate probes in undisturbed soils. The probes were evaluated against measured volumetric soil water content (mm mm-1) on their accuracy, precision and repeatability to measure soil water content in the 26oC treatment (Chapter 2). Most of the laboratory derived equations had RMSE close to zero, on average at 0.003 mm mm-1 and precision (R2) ranged between 93 and 99% and accuracies up to 96%. These probes were found to be sensitive to soil temperature changes in the measurement of water content. Under wet to dry soil conditions about 48, 62 and 34% errors were obtained for the A, B and C-horizons, respectively and therefore, Department of Science and Technology

Image-guided robots have been widely used for bone shaping and percutaneous access to interventional sites. However, due to high-accuracy requirements and proximity to sensitive nerves and brain tissues, the adoption of robots in inner-ear surgery has been slower. In this paper the authors present their recent work towards developing two image-guided industrial robot systems for accessing challenging inner-ear targets. Features of the systems include optical tracking of the robot base and tool relative to the patient and Kalman filter-based data fusion of redundant sensory information (from encoders and optical tracking systems) for enhanced patient safety. The approach enables control of differential robot positions rather than absolute positions, permitting simplified calibration procedures and reducing the reliance of the system on robot calibration in order to ensure overall accuracy. Lastly, the authors present the results of two phantom validation experiments simulating the use of image-guided robots in inner-ear surgeries such as cochlear implantation and petrous apex access.

In this paper the use of RFID for EM field measurement is studied.

A calibration procedure for the non-linear effects in RFID IC is introduced and used to correct the measured fields., QC 20141013

In this article, the error-corrected determination of complex scattering parameters of multi-port devices by means of a 2-port vector network analyzer is presented. As only two ports of the device under test can be connected to the analyzer ports at a time, the remaining device ports have to be terminated by external reflections. In order to measure the scattering parameters of the DUT without the influence of systematic errors and of the external terminations, an error correction has to be performed besides the calibration. For this purpose, the application of the multi-port procedure is presented. This method has the advantage, that the external reflective terminations can be chosen arbitrarily. Furthermore, these terminations can be unknown except for one. An automatized measurement system based on a switching network is shown, which is optimized for the measurement of planar microwave circuits. An error model for the description of the measurement setup as well as a calibration procedure for the elimination of the systematic errors are presented.

To study traffic flow characteristics at freeways, traffic model s are used. One of these traffic models is the micro-dynamic traffic model Getram/AIMSUN2 (in this study referred to as AIMSUN2) developed at the Barcelona University of Technology (UPC). DHV Environment and Infrastructure is using this software package for traffic modelling in the Netherlands. To achieve sufficient accuracy between simulation outcomes and observations traffic models need to be calibrated. At this moment, a procedure to perform the calibration process for AIMSUN2 does not exist. The objective of this study is to design such as procedure. This study focuses on the driver behaviour on freeways. The objective of a calibration process is to estimate the unknown model parameters and to optimise the overall model performance. By definition, a simulation model generates output on multiple aspects such as flows, density and travel time. Each of these aspects is associated to it is own performance indicator. The overall performance of a model can be defined as a weighted sum of these indicators. The weights depend on the priorities of model experts, but are seldom made explicit. In this study a procedure is applied to determine these weights from revealed preferences of model experts. First, a problem analysis is performed to distinguish typical aspects of the calibration process. Possibilities to estimate unknown model parameters and optimisation processes to compute the distance between simulation outcomes and observations are defined. The optimisation processes is divided into a one dimensional and a multi-criteria analysis. During the one dimensional optimisation single criterion variables are observed while during the multi-criteria analysis the total performance (all examined criterion variables) of a model is examined. Various estimation techniques are distinguished to determine the model parameter values which are used within the mentioned optimisation processes.
