Woo, Heechul. "The selective low cost gas sensor based on functionalized graphene." Thesis, Université Paris-Saclay (ComUE), 2016. http://www.theses.fr/2016SACLX050/document.
Full textRecent advances in nanomaterials provided a strong potential to create a gas sensor with many advantages such as high sensitivity of single molecule detection, low cost, and low power consumption. Graphene, isolated in 2004, is one of the best promising candidate for the future development of nanosensors applications because of its atom-thick, two-dimensional structures, high conductivity, and large specific surface areas. Every atom of a monolayer graphene can be considered as a surface atom, capable of interacting even with a single molecule of the target gas or vapor species, which eventually results in the ultrasensitive sensor response.In this thesis work, graphene films were synthesized by Chemical Vapor Deposition (CVD) on the glass substrate. Raman spectroscopy was used to analyze the quality and number of layers of graphene. Atomic Force Microscope (AFM) and Scanning Electron Microscopy (SEM) were also performed to analyze the quality of graphene. After the characterization of graphene films, graphene based resistive devices (four identical electrodes are thermally evaporated directly onto the graphene film as metal electrodes) were fabricated. The electrical characterization has been carried out using Keithley-4200.Intrinsic device response was studied with different external condition changes (pressure, humidity, light illumination). The device was non-covalently functionalized with organometallic complex (Ru(II) trisbipyridine) and the its light exposure response was studied. The observed device response was reproducible and similar after many cycles of on and off operations. The theoretical and experimental approaches and the results obtained during the thesis are opening up a way to understand and fabricate future gas sensing devices based on the non-covalentely functionalized graphene

Full textThis PhD aims at reconstructing atmospheric CH4 concentrations from voltage signals recorded by low-cost Metal Oxide Sensors (MOS) for the purpose of monitoring CH4 leaks from an industrial facility. Our strategy is based on the collocation of measurements by low-cost sensors and expensive very high accuracy instruments. The CH4 concentrations data from the high accuracy reference instrument are then used as a target variable to be reconstructed using MOS voltage and other predictors. The reconstruction is performed with both machine learning models and parametric models. It is applied to increasingly complex problems, including the reconstruction of: 1) smooth variations of ambient room air CH4 in a laboratory, 2) fast and large variations of CH4 during concentration spikes generated on a test bench in a laboratory with a typical signature similar to that observed for real world leaks, and 3) fast and large variations of CH4 observed in the field during a dedicated controlled release experiment. The first laboratory experiments revealed a high influence of H2O in MOS sensors, and the reconstruction with a Multilayer perceptron model showed good agreement between the references and the reconstructed room air concentrations (Chapter 2). The results of the second experiment (Chapter 3) showed the importance of the selection of the sensor's type in order to produce reconstructions of CH4 concentration with a 1 ppm accuracy (RMSE). We also discovered that the TGS 2611-C00 sensors provided a more accurate reconstruction of CH4 spikes than the TGS 2611-E00 ones. A parsimonious model training strategy allowed us to restrict the training set from 70% to 25% of the data without a degradation in the reconstruction of the CH4 spikes. Emission of controlled releases from reconstructed CH4 concentrations measured by MOS sensors and the inversion of a Gaussian atmospheric model (Chapter 4) were similar to those inverted from high accuracy reference data, with an average emission rate estimation error of 25% over 11 controlled releases and a location error of 9.5 m. The results of this PhD are the basis to explore advanced techniques based on machine learning to produce accurate estimates of CH4 concentrations, and study the information required by inversion modelling that produced best estimates of the emission rate and location of CH4 leaks

Full textIndoor Air Quality (IAQ) knowledge is necessary to address the sanitary and socio-economic issues of this field, in both public and private domains. Laboratory-grade measuring devices are generally burdensome and expensive. Alone, they cannot provide a full response to large-scale IAQ information needs. This work focuses on the use of two alternative methods in this context, which are IAQ modeling and the use of low-cost sensors, with the purpose of removing certain barriers to their deployment. As a first step, this manuscript describes the numerical developments made in order to enrich a library of models for nodal modeling of IAQ, initiated by EDF R&D. The main additions include the modeling of humidity and indoor particle deposition. In order to evaluate the relevance of the choices made, a validation work has been carried out by confronting the IAQ library results with analytical solutions, experimental data and other modeling tools. One of the major issues of this type of modeling method is the complex choice of input data. This step can have a significant impact on the results provided and there is a need to assess their influence. The modeling of various mono-zone or multi-zone case studies, from the residential and tertiary sectors, has highlighted the advantages and the limitations of the developed tool regarding the quality of the predictions of the concentrations of gaseous and particulate pollutants. A sensitivity analysis was carried out to identify the key parameters responsible for model uncertainty in a few configurations. As a second step, an innovative method of particulate matter measurement has been developed, associating several low-cost particle sensors. This approach allowed to tackle the issues of reliability of this kind of sensors and the limitations of their detection capabilities. The design of prototypes and their use in different indoor environments have given promising results. Several developments are then proposed in order to generalize and validate the robustness of this approach

Particulate Matter (PM) pollution continues to be an important global environmental issue and raises increasing concerns for public health. The strong correlation between personal health impact and actual local exposure creates a huge demand for air particulate sensors meant for small-scale measurement. However, today's air particulate monitoring technologies suffer from high cost, high power requirements, or large size, which presents an opportunity to create low-cost, compact, and low-power sensors that are desired for block-level, household, automobile, or even personal-level monitoring. In this thesis, the basic concept components of a novel PM monitoring method based on capture and imaging are developed and validated. Two capture techniques, electrostatic precipitation (ESP) and fiber-filtration, are demonstrated and verified with corresponding imaging results. Particulates captured either on flat substrate or aligned fibers are illuminated by LED light source with a glancing angle, or with the help of waveguides. Light scattered from the particles is detected by a CMOS camera module, yielding the particle size distribution and also revealing the morphology and properties of particulates. The results suggest that, with proper data analysis, this approach has the potential to monitor the real-time PM level of the sampled air and also classify between different particle sources. A detection limit of 200 nm is demonstrated and two kinds of pollens are notably distinguished from solid dust particulates. Additional, assorted replenishment schemes are designed to ensure a long, maintenance-free operational life.

Full textThis thesis describes the design and implementation of a low-cost high speed data capture card for the Hubble Sphere Hydrogen Survey (HSHS). The Hubble Space Hydrogen Survey was initiated in an effort to build a low-cost cylindrical radio telescope for an all sky redshift survey with the observational goal to produce a 3-dimensional mapping of the bulk Hubble Sphere using Hydrogen 21cm emissions. This dissertation ï¬ rst investigates the system design to see how each of the user speciï¬ cations set by the planning team could be achieved in terms of design decisions, component selection and schematic capture. The final design. AstroGIG, satisï¬ es the user speciï¬ cations by capturing data up to a full power bandwidth of 1.7GHz with an instantaneous bandwidth of ≤ 250MHz white maximizing the dynamic range. AstroGIG buffers, processes, stores and ï¬ nally transmits the data through a 4-lane PCI-Express interface to a standard PC where the majority of the processing is performed. The system implementation is then described where issues relating to the process of transforming schematics into a physical PCB, and HSHS integration are discussed. The design is veriï¬ ed through Hyperlynx simulations to give a high degree of certainty that physical implementation and production would be successful. Results from tests on the actual hardware characterizing the overall system performance are presented. Conclusions are drawn based on these results and suggestions for future work and design improvements are recommended.
Le, Xuan-Chien. "Improving performance of non-intrusive load monitoring with low-cost sensor networks." Thesis, Rennes 1, 2017. http://www.theses.fr/2017REN1S019/document.
Full textIn smart homes, human intervention in the energy system needs to be eliminated as much as possible and an energy management system is required to automatically fluctuate the power consumption of the electrical devices. To design such system, a load monitoring system is necessary to be deployed in two ways: intrusive or non-intrusive. The intrusive approach requires a high deployment cost and too much technical intervention in the power supply. Therefore, the Non-Intrusive Load Monitoring (NILM) approach, in which the operation of a device can be detected based on the features extracted from the aggregate power consumption, is more promising. The difficulty of any NILM algorithm is the ambiguity among the devices with the same power characteristics. To overcome this challenge, in this thesis, we propose to use an external information to improve the performance of the existing NILM algorithms. The first proposed additional features relate to the previous state of each device such as state transition probability or the Hamming distance between the current state and the previous state. They are used to select the most suitable set of operating devices among all possible combinations when solving the l1-norm minimization problem of NILM by a brute force algorithm. Besides, we also propose to use another external feature that is the operating probability of each device provided by an additional Wireless Sensor Network (WSN). Different from the intrusive load monitoring, in this so-called SmartSense system, only a subset of all devices is monitored by the sensors, which makes the system quite less intrusive. Two approaches are applied in the SmartSense system. The first approach applies an edge detector to detect the step-changes on the power signal and then compare with the existing library to identify the corresponding devices. Meanwhile, the second approach tries to solve the l1-norm minimization problem in NILM with a compositional Pareto-algebraic heuristic and dynamic programming algorithms. The simulation results show that the performance of the proposed algorithms is significantly improved with the operating probability of the monitored devices provided by the WSN. Because only part of the devices are monitored, the selected ones must satisfy some criteria including high using rate and more confusions on the selected patterns with the others

Full textTracking sensors in a wireless network leads to many applications. However, current techniques based on the received signal strength are unreliable given the stability of measurements. More accurate techniques inspired from radars have been proposed but they require an expensive radio. However, one of the most difficult aspects regarding the localization in a wireless sensor network remains their inadequacy with their low-cost and low-power characteristics. For example, clock generation of ZigBee modems introduce strong uncertainties regarding the reliability of measurements. Demanding digital algorithms must be carefully studied and improved in order not to exceed requirements defined by industrials. In other words, the purpose is to design an implementation as cheap as possible while keeping a minimum accuracy. The work of this thesis focuses on two main objectives: the development of a digital circuit capable of calculating time of arrivals, and the development of prototypes for a future positioning feature. The main constraint is the use of a single channel from the ZigBee 802.15.4 standard. This work enabled to understand issues regarding the distance measurements and adapt them given wireless sensor network constraints

Full textEstimation in robotics is an important subject affected by trade-offs between some major critera from which we can cite the computation time and the accuracy. The importance of these two criteria are application-dependent. If the computation time is not important for off-line methods, it becomes critical when the application has to run on real-time. Similarly, accuracy requirements are dependant on the applications. EKF estimators are widely used to satisfy real-time constraints while achieving acceptable accuracies. One sensor widely used in trajectory estimation problems remains the inertial measurement units (IMUs) providing data at a high rate. The main contribution of this thesis is a clear presentation of the preintegration theory yielding in a better use IMUs. We apply this method for estimation problems in both pedestrian and humanoid robots navigation to show that real-time estimation using a low- cost IMU is possible with smoothing methods while formulating the problems with a factor graph. We also investigate the calibration of the IMUs as it is a critical part of those sensors. All the development made during this thesis was thought with a visual-inertial SLAM background as a mid-term perspective. Firthermore, this work tries to rise another question when it comes to legged robots. In opposition to their usual architecture, could we use multiple low- cost IMUs on the robot to get valuable information about the motion being executed?

Full textEnhancing road safety by developing active safety system is the general purpose of this thesis. A challenging task in the development of active safety system is to get accurate information about immeasurable vehicle dynamics states. More specifically, we need to estimate the vertical load, the lateral frictional force and longitudinal frictional force at each wheel, and also the sideslip angle at center of gravity. These states are the key parameters that could optimize the control of vehicle's stability. The estimation of vertical load at each tire enables the evaluation of the risk of rollover. Estimation of tire lateral forces could help the control system reduce the lateral slip and prevent the situation like spinning and drift out. Tire longitudinal forces can also greatly influence the performance of vehicle. The sideslip angle is one of the most important parameter to control the lateral dynamics of vehicle. However, in the current market, very few safety systems are based on tire forces, due to the lack of cost-effective method to get these information. For all the above reasons, we would like to develop a perception system to monitor these vehicle dynamics states by using only low-cost sensor. In order to achieve this objective, we propose to develop novel observers to estimate unmeasured states. However, construction of an observer which could provide satisfactory performance at all condition is never simple. It requires : 1, accurate and efficient models; 2, a robust estimation algorithm; 3, considering the parameter variation and sensor errors. As motivated by these requirements, this dissertation is organized to present our contribution in three aspects : vehicle dynamics modelization, observer design and adaptive estimation. In the aspect of modeling, we propose several new models to describe vehicle dynamics. The existent models are obtained by simplifying the vehicle motion as a planar motion. In the proposed models, we described the vehicle motion as a 3D motion and considered the effects of road inclination. Then for the vertical dynamics, we propose to incorporate the suspension deflection to calculate the transfer of vertical load. For the lateral dynamics, we propose the model of transfer of lateral forces to describe the interaction between left wheel and right wheel. With this new model, the lateral force at each tire can be calculated without sideslip angle. Similarly, for longitudinal dynamics, we also propose the model of transfer of longitudinal forces to calculate the longitudinal force at each tire. In the aspect of observer design, we propose a novel observation system, which is consisted of four individual observers connected in a cascaded way. The four observers are developed for the estimation of vertical tire force, lateral tire force and longitudinal tire force and sideslip angle respectively. For the linear system, the Kalman filter is employed. While for the nonlinear system, the EKF, UKF and PF are applied to minimize the estimation errors. In the aspect of adaptive estimation, we propose the algorithms to improve sensor measurement and estimate vehicle parameters in order to stay robust in presence of parameter variation and sensor errors. Furthermore, we also propose to incorporate the digital map to enhance the estimation accuracy. The utilization of digital map could also enable the prediction of vehicle dynamics states and prevent the road accidents. Finally, we implement our algorithm in the experimental vehicle to realize real-time estimation. Experimental data has validated the proposed algorithm

Full textThe drivers of Powered Two Wheels vehicles are considered among the most vulnerable road users, as attested by the number of crashes increasing every year. The significant part of mortalities related to single vehicle “without identifying a third party” is related to the loss of control in bends. These thesis work is based on an instrumented motorcycle platform with a multi-sensor system. We have proposed algorithms to accurately reconstruct motorcycle trajectories achieved when negotiating bends. This system is intended to objectively evaluate and examine the behavior of drivers when negotiating bends in order to better train them. The goal is to lead them to adopt a safe trajectory in order to improve the road safety. Data required for the trajectory reconstruction are acquired using an instrumented motorcycle embedding several redundant sensors (reference sensors and low-cost sensors) that measure the rider’s actions (roll, steering) and the motorcycle behavior (position, velocity, acceleration, odometry, heading and attitude). This work is a part of the ARN project VIROLO++. The solution we have proposed allows to reconstruct bikes trajectories in bends with acceptable accuracy. The developed algorithm will be used to objectively evaluate and examine how riders negotiate bends. The embedded system carrying this algorithm can be used for the initial training and retraining in order to better train motorcycle drivers to estimate a safe trajectory and thus ensure safety when taking bends

The optical galvanic isolation unit is a photodetector that is responsiblefor transferring the gating information signal from an external control unit to the powerswitch. The necessary energy to switch the power device is provided by means of a TIAfollowed by a gate driver.

Full textThe harmful effects of air pollution need a high-resolution concentration estimate. Ambient pollutant concentrations are routinely measured by surface monitoring sites of local agencies (AIRPARIF in Paris area, France). Such networks are not dense enough to represent the strong horizontal gradients of pollutant concentrations over urban areas. And, high-resolution models that simulate 3D pollutant concentration fields have a large spatial coverage but suffer from uncertainties. Those both information sources exploited independently are not able to accurately assess an individual’s exposure. We suggest two approaches to solve this problem : (1) direct pollution measurement by using low cost mobile sensors and reference instruments. A high variability across pollution levels is shown between microenvironments and also in the same room. Mobile sensors should be deployed on a large scale due to their technical constraints. Reference instruments are very expensive, cumbersome, and can only be used occasionally. (2) by combining concentration fields of the Parallel Micro-SWIFT-SPRAY (PMSS) model over Paris at a horizontal resolution of 3 meters with AIRPARIF local ground stations measurements. We determined “representativeness areas” - perimeter where concentrations are very close to the one of the station location – only from PMSS simulations. Next, we developed a Bayesian model to extend the stations measurements within these areas

Full textThe objective of this thesis is to design a low-cost gas sensor array for outdoor gas pollutants monitoring and to develop adapted standardization and data analysis methods. The device aims is to contribute to the densification of the current atmospheric pollution-monitoring network for better spatial and temporal resolution. First, we select electrochemical and metal oxide gas sensors capable to detecting and quantifying low concentrations of nitrogen dioxide and ozone in ambient air near a highway. We have characterized these micro-sensors in the laboratory using a diffusing controller system and tested them in the field by following procedures inspired from the evaluation protocol of low cost gas sensors proposed by the European Joint Research Center (JRC). The individual analysis of the data from each sensor highlights the need to merge the responses of all the sensors as well as the values of the temperature and the humidity of the atmosphere using multivariate methods of classification. The performance of several classification methods generally used in the field of multi-sensor gas systems was studied. This comparison leads us to choose Support Vector Machine regression (SVM) thanks to its performance in terms of precision and robustness. We also conduct a study on the optimization of the SVM hyper-parameters using optimization algorithms. The Generalized Pattern Search algorithm (GPS) was chosen among other algorithms due to its simplicity and reliability. Then, we highlight the problem of sensor drift over time and the need for periodic calibration. We proposed a standardization method based on SVM regression, thereby reducing the cost and the effort of full recalibration. This standardization method was also used for calibration transfer between several identical systems in order to avoid individual calibration of each system. The research work elaborated in this PhD was published in two journal papers and two IEEE conference papers

It is popular to make 3D cartoon with a computer with the fast progressing of the computer technology. It take much time and much money to make 3D cartoon by manpower only, and the moving object of the produced movie is limited. So it is popular to catch the true performer's movements by the motion capture system, then apply it to the cartoon. At the present, two kinds of the most popular motion capture system on the market, one is the image type and the other is the electromagnetic type.However, the two kinds of the motion capture system are very expensive and heavy, so that the motion capture system can not be popularized. This paper is concerned with a special topic to make a motion capture system with light weight, and low price, the main characteristic has: 1.Bend sensors are used to detect the attitude of a person. 2.A MSP430F149 single chip computer is used to read and to transmit the attitude data. 3.A MX25L1602 Flash ROM is used as storing device and calibrating data. 4.A bluetooth chip is used for communicating media. 5.The attitude data will translated to physical angles by a VISUAL BASIC program. 6.The attitude of the human body will dynamically showed in graphic by a FLASHMX multimedia player. 7.A calibrating procedure is done in user friendly interface, such that the system can be suitable for different bend sensors and human characteristics. 8.The system is with record function and play function such that it can be applied to sport training and medical treatment. 9.The system is used as the input device of a digital game.

Full textIn the last decades there has been a steep decrease in the price of electronics. This decrease has favored an exponential increase of all types of consumer electronics. The ubiquity of these devices makes them almost inseparable from their users. One area benefiting and at the same time further increasing this ubiquity is the Internet of Things, IoT, in other words the possibility of having a constant connection and data sharing amongst the most diverse devices. In parallel with the development of IoT solutions designed for Industrial use, some other low-cost devices such as the Arduino have appeared, which enable the development of small IoT projects economically. Besides the Arduino other products such as the ESP8266 and ESP32 boards by Espressif have been gaining popularity in recent years. The aim of this project is the development of a low cost, autonomous monitoring solution that is of use for the academic community. This system should collect environmental data such as temperature, humidity, noise pollution and make an estimation of the occupancy of a certain zone through the ubiquity of mobile devices by capturing their Wi-Fi request probes. The information collected will be made available for the academic community, giving the possibility of students to select the best study room based on the occupancy or noise level of the different rooms. The main constituents of the project are the ESP32s with the associated sensors named Sensing Boxes, and the necessary software component and infrastructure to process the data collected and provide it to interested parties. In addition to this main objective, it is important to understand and document the potentialities of the ESP32 in low-cost projects as its development methodologies available. In a sense provide a guideline of the most important topics about this board and some sensors for anyone developing a project of similar nature. The system was tested in two contexts, one of domestic nature, and in order to fine tune and debug the system, the other in the context to which it was originally idealized, the campus of University of Madeira.
