Abstract (sommario):

Inductor–capacitor (LC) passive wireless sensors are widely used for remote sensing. These devices are limited in applications where multiparameter sensing is required, because of the mutual coupling between neighboring sensors. This article presents two effective decoupling techniques for multiparameter sensing, based on partially overlapped sensors and decoupling coils, which, when combined, reduce the mutual coupling between sensors to near zero. A multiparameter LC sensor prototype with these two decoupling mechanisms has been designed, simulated, and measured. This prototype is capable of simultaneously measuring four parameters. The measurements demonstrate that the changes in capacitance in one individual sensor do not affect the measurements of the other sensors. This principle has been applied to simultaneous wear sensing using four identical wear sensors.

Abstract (sommario):

<span>Real-time transmission of biomedical signals is immensely challenging and requires cloud and internet of things (IoT) infrastructure. Security is also an important factor; however, to accomplish this, a reconstruction method is developed in which the entire signal is supplied as an input, the primary portion is considered here, and the signal is further encoded and transmitted to the destination. Electrocardiogram (ECG) compression for the lightweight wireless network is quite challenging for long-term healthcare monitoring. Compressed sensing (CS) involves efficient encoding mechanisms for error rate estimation for reconstruction and energy consumption for wireless transmission of data. We propose a multi-task compressed sensing (MT-CS) reconstruction mechanism in this study for ECG compression of data is most chosen for a wireless network system that has various sensors embedded in it. This model further extracts the essential adaptive features for correlation existing in the ECG signals. The performance of the proposed MT-CS reconstruction mechanism is evaluated on the multiparameter intelligent monitoring in intensive care (MIMIC-II) dataset, which ensures its robustness and generalization. The results obtained upon simulation ensure that the proposed MT-CS based reconstruction approach ensures excellent reconstruction signal with fewer measurements in comparison with the existing state-of-art CS techniques.</span>

Abstract (sommario):

A close correlation between CO2 concentration and aerosol enables the wide utilization of CO2 concentration as a good representation of Severe Acute Respiratory Syndrome-Coronavirus-2 infection airborne transmission. On the other side, many indoor air-quality monitoring devices have been developed for indoor monitoring applications. However, most of them are multiparameter air-quality sensor systems and tend to consume relatively high power, are relatively large devices, and are fairly expensive; therefore, they not meet the requirement for indoor monitoring applications. This paper presents a smart wireless sensor node that can measure and monitor CO2 concentration levels. The node was designed to meet the requirements of indoor air-quality monitoring applications by considering several factors, such as compact size, low cost, and low power, as well as providing real-time, continuous, reliable, and remote measurement. Furthermore, the commercial off-the-shelf and low-power consumption components are chosen to fit with the low-cost development and reduce energy consumption. Moreover, a low-power algorithm and cloud-based data logger also were applied to minimize the total power consumption. This power strategy was applied as a preliminary development toward an autonomous sensor node. The node has a compact size and consumes low energy for one cycle of CO2 measurement, accompanied by high accuracy with very low measurement error. The experiment result revealed the node could measure and monitor in real-time continuous, reliable, and remote CO2 concentration levels in indoor and outdoor environments. A user interface visualizes CO2 concentration graphically and numerically using the Adafruit platform for easy accessibility over the Internet of Things. The developed node is very promising and suitable for indoor CO2 monitoring applications with the acquired data that could be utilized as an indicator to minimize the risk of indoor Severe Acute Respiratory Syndrome-Coronavirus-2 airborne transmission.

Abstract (sommario):

Introduction. The relevance of work is due to the need for constructive transformation of the AАEE-7 multi-block measuring system into a mono-block one. This is required for microclimate research in livestock premises, according to the methodological provisions. The work on the development of a laboratory sample of a mono-block analyzer is being carried out in Ukraine for the first time. The purpose of the research was to implement a method of continuous automatic recording of measurements of the microclimate of livestock premises. In addition, it was supposed to reduce the cost and reduce the number of technical means of measurement. It was also supposed to simplify the process of setting up measurements to increase the productivity of scientists and technologists. Research methods. Analytical, mathematical, physical, economic research methods are applied. In addition, the methods of designing and programming electronic devices are applied. On the basis of previous developments and materials of scientific works of periodical publications, the advantages of the measuring system "Analyzer of air environment electronic mono-block" (AАEE-M) are substantiated. A laboratory sample of the device with software was made (developer Cherkasy Research Station of Bioresources NAAS). The algorithm of the multiparameter method of continuous automatic registration and assessment of the microclimate of premises using AАEE-M has been developed. Research results. It was determined that the devices of the main Ukrainian manufacturers PJSC "Ukranalit" and LLC "Complex Automated Systems" and foreign companies "Delta Ohm" and "Luma Sense Technologies A/S" do not fully meet the requirements of microclimate monitoring, according to the existing methodology. The main innovative advantage of AАEE-M is the possibility of automatic registration of daily fluctuations of at least ten parameters of the microclimate, with a time interval of 6 minutes. This applies, in particular, to small particles of suspended dust of PM1, PM2.5 and PM10 fractions and low volumetric concentrations of polluting gases CO2, NH3, H2S, CH4. The technical advantage of the measuring system is based on the fact that it is characterized by a 30 % lower mass compared to the Ecolab prototype. In addition, it has 9 times longer battery life, wireless communication, and the possibility of remote transmission of measurement results. Conclusions. For the operation of the AАEE-M measuring system, a methodology for assessing microclimate parameters using the method of continuous automatic registration has been developed. The economic advantage of AАEE-M is that it is 4.4 times cheaper compared to the prototype. Also, it is cheaper by 22.9 %, compared to the previous multi-block modification of the measuring system. Key words: measuring system, parametric, evaluation, microclimate, livestock premises, method of determination.

Abstract (sommario):

Abstract Conventional usage of multiparameter radar measurements for rainfall estimation has been associated with tracking the variability of the raindrop size distribution. The use of multiparameter radar measurements in a statistical framework to estimate rainfall is presented in this paper. The techniques developed in this paper are applied to the radar and rain gauge measurement of rainfall observed on 26 July 1991, during the Convection and Precipitation Electrification program. Conventional pointwise estimates of rainfall are also compared. The probability matching procedure, when applied to the radar and surface measurements shows that multiparameter radar algorithms can match the probability distribution functions better than the reflectivity based algorithms, thereby indicating the potential of multiparameter radar measurements for statistical approach to rainfall estimation.

Abstract (sommario):

Multiparameter quantum estimation is made difficult by the following three obstacles. First, incompatibility among different physical quantities poses a limit on the attainable precision. Second, the ultimate precision is not saturated until you discover the optimal measurement. Third, the optimal measurement may generally depend on the target values of parameters, and thus may be impossible to perform for unknown target states. We present a method to circumvent these three obstacles. A class of quantum statistical models, which utilizes antiunitary symmetries or, equivalently, real density matrices, offers compatible multiparameter estimations. The symmetries accompany the target-independent optimal measurements for pure-state models. Based on this finding, we propose methods to implement antiunitary symmetries for quantum metrology schemes. We further introduce a function which measures antiunitary asymmetry of quantum statistical models as a potential tool to characterize quantumness of phase transitions.

Abstract (sommario):

Les machines électriques de forte puissance sont soumises à des contraintes mécaniques, thermiques et magnétiques sévères en fonctionnement. Pour assurer leur fiabilité et la continuité de leur opération, il est crucial de disposer d'informations en temps réel sur ces contraintes, souvent à l'échelle locale. Les technologies de capteurs sans fil et sans batterie, combinées à des techniques efficaces d'analyse des données et de traitement des signaux, sont indispensables pour répondre à ce besoin. Les ondes acoustiques de surface permettent de concevoir des capteurs sans fil et totalement passifs, capables de mesurer de nombreuses grandeurs physiques telles que la température, les contraintes mécaniques et le champ magnétique, grâce à une ingénierie avancée du design. Le travail réalisé dans cette thèse a permis de développer des capteurs SAW multi-grandeurs pour la mesure des déformations, de la température et du champ magnétique. Ces capteurs ont d'abord été calibrés sur des bancs d'essais en laboratoire, puis utilisés pour caractériser les propriétés mécaniques, telles que la magnétostriction, et les propriétés magnétiques, telles que les pertes magnétiques, des tôles ferromagnétiques employées dans la conception des machines électriques de forte puissance. La caractérisation des propriétés des tôles ferromagnétiques est cruciale pour plusieurs raisons : concevoir des systèmes électromagnétiques efficaces, minimiser les vibrations et les bruits indésirables, contrôler la dissipation d'énergie, prévenir la fatigue des matériaux, optimiser la conception des composants pour l'efficacité énergétique et développer des composants résistants à la chaleur pour la fiabilité et la durabilité... Le projet de thèse implique l'entreprise JEUMONT Electric (société de haute technologie spécialisée dans les solutions de conversion d'énergie), le groupe AIMAN-FILMS de l’IEMN et l'équipe Outils et Méthodes Numériques du L2EP. Chaque partenaire apporte des compétences spécifiques pour aborder l'instrumentation multi-physique des machines électriques de forte puissance
High-power electrical machines are subjected to severe mechanical, thermal, and magnetic stresses during operation. To ensure their reliability and continuous operation, it is crucial to have real-time information on these constraints, often at a local scale. Wireless and battery-free sensor technologies, combined with effective data analysis and signal processing techniques, are essential to meet this need. Surface acoustic waves (SAW) allow the design of wireless and completely passive sensors capable of measuring various physical quantities such as temperature, mechanical stress, and magnetic fields, thanks to advanced design engineering. The work carried out in this thesis has enabled the development of multi-quantity SAW sensors for measuring deformations, temperature, and magnetic fields. These sensors were first calibrated on laboratory test benches and then used to characterize the mechanical properties, such as magnetostriction, and magnetic properties, such as magnetic losses, of ferromagnetic sheets used in the design of high-power electrical machines. Characterizing the properties of ferromagnetic sheets is crucial for several reasons: designing efficient electromagnetic systems, minimizing vibrations and unwanted noise, controlling energy dissipation, preventing material fatigue, optimizing component design for energy efficiency, and developing heat-resistant components for reliability and durability. The thesis project involves JEUMONT Electric (a high-tech company specializing in energy conversion solutions), the AIMAN-FILMS group from IEMN, and the Numerical Tools and Methods team from L2EP. Each partner brings specific expertise to address the multi-physical instrumentation of high-power electrical machines

Abstract (sommario):

Performance Measurement of the IP packet networks mainly comprise of monitoring the network performance in terms of packet losses and delays. If used appropriately, these network parameters (i.e. delay, loss and bandwidth etc) can indicate the performance status of the network and they can be used in fault and performance monitoring, network provisioning, and traffic engineering. Globally, there is a growing need for accurate network measurement to support the commercial use of IP networks. In wireless networks, transmission losses and communication delays strongly affect the performance of the network. Compared to wired networks, wireless networks experience higher levels of data dropouts, and corruption due to issues of channel fading, noise, interference and mobility. Performance monitoring is a vital element in the commercial future of broadband packet networking and the ability to guarantee quality of service in such networks is implicit in Service Level Agreements. Active measurements are performed by injecting probes, and this is widely used to determine the end to end performance. End to end delay in wired networks has been extensively investigated, and in this thesis we report on the accuracy achieved by probing for end to end delay over a wireless scenario. We have compared two probing techniques i.e. Periodic and Poisson probing, and estimated the absolute error for both. The simulations have been performed for single hop and multi- hop wireless networks. In addition to end to end latency, Active measurements have also been performed for packet loss rate. The simulation based analysis has been tried under different traffic scenarios using Poisson Traffic Models. We have sampled the user traffic using Periodic probing at different rates for single hop and multiple hop wireless scenarios. 5 Active probing becomes critical at higher values of load forcing the network to saturation much earlier. We have evaluated the impact of monitoring overheads on the user traffic, and show that even small amount of probing overhead in a wireless medium can cause large degradation in network performance. Although probing at high rate provides a good estimation of delay distribution of user traffic with large variance yet there is a critical tradeoff between the accuracy of measurement and the packet probing overhead. Our results suggest that active probing is highly affected by probe size, rate, pattern, traffic load, and nature of shared medium, available bandwidth and the burstiness of the traffic.

Abstract (sommario):

This licentiate thesis presents an advanced wireless system, built on a single hardware platform, for applications in medicine and health. In order to design a single system, adaptable for different context, an accurate system specification is required. The technical requirements are authenticated by actual tests in the environment where the system is intended to be used. The results of these measurements give an understanding of the possibilities of designing a real system but also acts as a base for deriving the empirical formulas to be used as the basis of the development and verification. In summary, this work has included a larger measurement campaign and a verification of subsystems to support the development of wireless systems on a single hardware platform. This can be used for different measurements in medical healthcare and rescue work. Previous systems for endurance tests have limitations in that they are not adapted to different sizes of mammals and they also have shortcomings in the quantification of data and scalability. The developed system was validated on mice and humans. On mice the measurement parameters was the hormone dopamine and locomotion. For humans it was measured time for given distances. Both validation tests showed high correlation with the respective reference methods. The correlation coefficients of mice between the developed system and the former system ranged from 0.916 to 0.967. In the validation with humans, runners were clocked by the system clock and a manual stop watch. The lowest correlation coefficient was 0.864. Advantages with the developed system is that it is scalable and measures the activity level quantitatively in the unit meters and it can also be used for different sizes of mammals in different environments. In tracking devices for rescue it is important that the transmitted signal can be detected at distances as large as possible. A support in the design work is to simulate path loss. This requires a path loss exponent, which was calculated after the measurement campaign. The results showed that the exponent of the height dependency decreases with antenna height above water. For the frequency 200 MHz, the exponent for the antenna height is 0.4 (vertical polarization) and 1.5 (horizontal polarization). For the distance dependency, the exponent was 3.59 (vertical polarization) and 3.22 (horizontal polarization). The path loss exponent is 2 for both the free space- and the ground reflection model. An antenna’s physical dimension is to a large extent dependent on the lowest frequency. The research’s aim was to reduce the physical size by introducing a resonance frequency. The physical length was from the beginning 0.43 meter given by the lowest frequency used (0.7 GHz) and the antenna was reduced in size to 0.22 meter.

Abstract (sommario):

Low cost, low power wireless sensors (motes) promise to revolutionize environmental data collection, but are they currently refined enough for widespread use by hydrologists? Their viability as a replacement for traditional data collection techniques was investigated in a 7 ha forested watershed in south-western British Columbia. The watershed included 41 instrument clusters measuring air and soil temperature, humidity, throughfall, soil moisture content, overland flow and groundwater head. The foundation of each cluster was a data box containing a MDA300 data acquisition board and a MICA2 processor board from Crossbow Technologies, Inc.™ that allowed for short range wireless data collection. The 41 motes each recorded data every 15 minutes from July, 2006, to April, 2007. In addition to reporting on the reliability of the motes and sensors during the 10 months deployment, the high spatial and temporal resolution data collected by this study gave the opportunity for many analyses of catchment processes. As soil moisture and throughfall are two influential processes in the exchange of water between the earth and the atmosphere, these were the focus of the data analysis. The first analysis was a resampling experiment on seven different events selected from the full data set. Comparing 100 different subsamples each of 5, 10 and 20 points for throughfall and soil moisture showed if increasing the sample size eventually produced diminishing returns in the ability to reproduce the true catchment mean. With significant differences in prediction ability for both soil moisture and throughfall at times of differing hydrologic activity, this analysis provides further support for the theories of changing moisture states of soil moisture and threshold values for throughfall. The second analysis described how the organization of soil moisture and throughfall changed during a range of weather conditions and timescales. Spatial representation of normalized values and Pearson correlation coefficients showed that there were distinct differences between wet and dry periods for soil moisture and between long and short analysis periods for throughfall.

Abstract (sommario):

Wireless Sensor Network (WSN), a collection of “sensor nodes” promises to change the scientist’s approach of gathering the environmental data in various fields. Sensor nodes can be used for non-stop sensing, event detection, location sensing and local control of actuators, this concept gives surety to many latest application areas like agriculture, military, home or factory automation, logistics and so on. Remote surveillance and measurement missions can be performed by using WSNs. The hot research topic now-a-days is to make such networks remotely controllable and adaptive to the environment and mission.

The work carried out in this thesis is the development of a surveillance application using TinyOS/nesC. The purpose of this application is to perform event-detection mission by using any one of the built-in sensor on Mica2 motes as well as a setup protocol is designed to make the WSN remotely controllable and adaptive to the mission. In this thesis, an experimental work is also performed using TinyDB to build up a surveillance system whose purpose is to detect and count the total number of person present at any time in a given room and to view the results at a remote place. Besides these two system applications, a comparative study between TinyDB and nesC is described which concludes that more hardware control can be achieved through nesC which is a more power efficient platform for long-term applications.

Abstract (sommario):

Multipath fading is a very common phenomenon in signal transmission over wireless channels. When a signal is transmitted over multipath channels, it is subject to reflection, diffraction and refraction. This results in multiple versions of the same signal to arrive at the receiver, each of which has suffered from various path loss, time-delay, phase shift and often also frequency shift. The latter is a result of Doppler shifts, which is experienced whenever a relative movement between the receiver and transmitter or scatterers is present. The communication environment changes quickly over location or time, thus introducing uncertainties to the channel response. Such channels result in increased system complexity, and the propagation effects need to be identified in order to predict the channel behaviour. Path loss is experienced in all types of radio channels, and its metrics are often determined by empirical path loss models. The path loss effects the mean received signal level, whereas large-scale fading (Shadowing) results in large-scale fluctuations of this received level. These variations are superimposed by the small-scale fluctuations, or small-scale fading, caused by multipath reception and Doppler shifts. Small-scale fading is simulated to gain a better understanding of these effects. In order to observe these effects satisfactory, the whole digital radio communication system chain must be simulated. Simulations are also performed for estimating the data capacity over both mobile and fixed multipath channels, and the resulting capacity of multipath reception exceeds the capacity of a flat channel due to increased received energy. In order to classify the effect of multipath channels on signal transmission, the profile of the channel for a given scenario has to be known, i.e. channel metrics such as the RMS delay spread is essential for a successful radio system design. A multipath channel profile and its RMS delay spread can be derived from a vast number of channel measurements performed for a given scenario. Measurements on the multipath channel impulse response have been performed, RMS delay spread has been calculated, and the procedure of the channel measurement process itself is simulated in Matlab.

Abstract (sommario):

Differential movement of a buried pipeline resulting from terrain instabilities such as subsidence, fault slippage, frost heave, ice scouring, soil movement, and landslide can create localized areas of high stress in a pipeline. These areas may be susceptible to mechanical failure and therefore may compromise the structural integrity of the line. Nondestructive testing (NDT) methods that can detect high-stress regions and measure the magnitude of the stress in the pipeline are needed to determine if or when remedial action must be taken to prevent stress-related damage. The areas of high stress can compromise the integrity of the pipeline, despite the fact that the highly stressed areas may not be readily detectable. �This report describes two phases of development for a nonintrusive technique to quantify the local, throughwall average axial stress in an exposed pipe. The technique selected for evaluation and development is a low-frequency, electromagnetic technique, called multiparameter magnetic measurement (MPMM). MPMM is a combination of existing magnetic techniques including magnetic hysteresis measurement, nonlinear harmonic analysis, and multiparameter correlation. The work included both a proof-of-principle demonstration of the technique using samples of grade X-42, X-46, and X-52 pipe (Phase I), and further determination of practical applicability of the MPMM technique (Phase II). Phase II focused on evaluating the variability of magnetic response to stress among five samples of grade X-42 pipe.
