This paper presents a contactless measurement system for an array of resistive sensors that exploits a low-frequency (LF) RFID-based approach. The system is composed of an interrogation unit (reader) which powers the sensor unit and exchanges measurement data with it. The sensor unit exploits a transponder operating at 134.2 kHz and a microcontroller. The transponder receives power from the reader and transfers data through the RF-link. The microcontroller sequentially measures the elements of a sensor array composed of six resistors with one common terminal. The adopted technique relies on the evaluation of the charging time of a capacitor through the measured resistor. By exploiting a known reference resistor this technique is theoretically independent from the values of the capacitor and of the supply voltage. A prototype has been developed showing operative distances of up to few centimeters and reads faster than one element of the array per second.

In the last years, measuring instruments have become quite complex due to the integration of embedded hardware and software components and the increasing aggregation of new features. Consequently, metrological regulation and control require more efforts from notified bodies, becoming slower and more expensive. In this work, we evaluate how blockchains can help to overcome such challenges. We propose a conceptual model for implementing measuring instruments in a distributed blockchain-based architecture, and compare it with traditional measuring instruments and distributed measuring models discussed in previous works. We also develop a security analysis, demonstrating that blockchains-based measuring systems can impact how measuring instruments are used in consumer relations, at the same time that improve security and simplify metrological regulation and control. At the end, we point out the main challenges, suggesting alternatives and potential research lines for future works.

Geopolymers are structural materials that can be used as a viable alternative to ordinary portland cement concrete. However, their widespread adoption has been limited by the lack of understanding in their fundamental reaction mechanisms. Microwave characterization methods have shown promise at understanding these reaction mechanisms. However, the complex dielectric properties of geopolymer precursor powders and the effect of void content must first be understood. Therefore, in this work, the dielectric properties of two geopolymer precursor powders (blast furnace slag and fly ash) are measured. Then, the effect of void content and particle size distribution (PSD) is considered on the measured dielectric properties. By characterizing the inherent void content of these powder materials, this effect can be removed and therefore the true dielectric properties of the materials can be determined. The results show that the void content has a significant effect on the measured dielectric properties.

System and measurement uncertainties play a key role in finding the reliability of complex and safety-critical structural systems such as buildings and bridges. Current mainstream techniques in structural reliability analysis use an iterative first-order reliability method that performs an indirect uncertainty evaluation by finding the most probable failure point. However, such an approach could lead to high computational time due to slower convergence, and in some cases, poor convergence that leads to unreliable results. In order to address the shortcomings, this paper applies a new high-order moment propagation technique (that was initially developed for the measurement uncertainty analysis) to structural reliability analysis problems aiming to obtain results that are simultaneously accurate and computational efficient. The proposed approach was implemented on a three-story elastic frame structure, and the presented results prove that the application of a technique from the field of measurement uncertainly can indeed be applied to complex problems in the structural reliability analysis in order to reduce the trade-off between accuracy and computational efficiency.

In the field of dynamic temperature measurement, the dynamic characteristics of sensors are critical and should meet test requirements. Thermocouples are widely used for temperature measurement in the harsh conditions due to their low cost, robustness and reliability. But there is a dynamic error in the dynamic temperature measurement, because of the presence of the thermal inertia. So it is important to dynamically calibrate the thermocouples and understand their dynamic characteristics. In this paper, based on the analysis of step and ramp excitation signal, a variety of dynamic calibration methods of thermocouples were introduced. The dynamic calibration system of thermocouple sensor based on high temperature furnace was established, and the dynamic calibration experiment of a bare thermocouple was done. The time constant of the thermocouple was obtained, and its estimation error is less than 1%.

Utilizing the Ultra-Wideband(UWB), the positioning system based on the Time of Fight (TOF) and Time Difference of Arrival (TDOA) is realized in this paper. The test results present that the positioning accuracy can reach the decimeter level. By analyzing and comparing the advantages and disadvantages of the two methods, a joint positioning system based on TOF and TDOA is proposed. Wireless clock synchronization of TDOA is analyzed and new method of clock synchronization is proposed. This joint positioning technique has advantages of TOF. Positioning speed was higher than TOF but lower than TDOA. It can be used to replace TOF overall and replace TDOA with low positioning speed required.

The thermal load of electromagnetic forming coil is one of the important factors affecting the long continuous service life of the coil. Study of thermal loads in forming coil during repeated EMF process is necessary before its industrialization, and is instructive to coil design. In this paper, several groups of repeated discharges experiments with two different coils were carried out. Fluorescence fiber measurement was applied in the experiments to acquire the coil temperature, and it was proved to be a suitable and promising method in measuring the temperature of electrical equipment. A finite element simulation model of plate forming coil has been established based on COMSOL Multiphysics. The experiment results showed good accordance with the simulation. The results proved that the coil reached an equilibrium temperature after a short period of time. By analyzing the equilibrium temperature, the effect of the crowbar circuit was verified, and a simple method of estimating coil temperature rise in repeated EMF processes based on discharge energy was proposed.

This paper presents a localization method for defects in CFRP plates. A comparison was made for scattering waves from a delamination and from an added block by finite element simulation. The results validate the use of an added mass to simulate the existence of a delamination. Experiments were conducted with magnets stick on the surface of the CFRP plate. The time of flight (ToF) for the scattering wave from magnets were obtained by wavelet transform and Hilbert transform. A probability matrix was constructed to locate the position of magnets. The points that match the ToF of the scattering wave were highlighted. By using four PZT sensors, six probability matrixes can be obtained for the six possible sensor pairs. Combing the results of six probability matrixes, the location of defect can be finally shown in an image of the plate.

The monitoring applications based on Wide Area Measurement Systems require a high level of synchronization for the time sources to give highly accurate synchronized measurements. The Phasor Measurement Units (PMUs) meet these requirements by providing the measurements obtained from the voltage and current signals with an absolute time reference referred to the Coordinated Universal Time, typically provided by Global Positioning System receivers. For a practical usability of the data provided by PMUs, the measurement results should be accompanied by a suitable information about their quality, so that the system operator can definitely rely on them. In this paper, the behavior of commercial PMUs under loss and restoration of the GPS signal is analyzed and discussed by means of experimental tests. The performance of the devices in terms of Total Vector Error are correlated with the time quality information sent by PMUs, according to the standard IEEE C37.118.2, together with the measurements during the transients corresponding to synchronization issues. The reported analysis allows putting in evidence important considerations about measurement accuracy and trustworthiness during synchronization issues and, in this perspective, highlights what are good practices in PMU implementation.

In this work a novel Molecularly Imprinted Polymer (MIP) able to bind PFAs (Perfluorinated Alkylated Substances) contaminants in water, combined with a plasmonic optical fiber sensor, is presented. The advantage of an MIP receptor is that it presents a better stability out of the native environment, very good reproducibility, low cost and, furthermore, it can be directly deposited on the gold sensing layer, without modifying the metal surface by functionalizing procedures. PFOA (Perfluorooctanoate) and PFOS (Perfluorooctanesulfonate) are the most extensively investigated PFAs because human exposition can occur through different pathways, and the dietary intake seems to be their main route of exposure. The experimental results have shown that the developed optical chemical sensor makes it possible to detect the above compounds. Sensor's response is exactly the same for PFOA, PFOS or PFAs contaminants. The limit of detection (LOD) of the developed chemical sensor was about 0.2 ppb, a value that is lower than the maximum residue limit fixed by the European Union regulations. This optical chemical sensor could be used for remote sensing, taking advantage of the capability of the optical fiber.
