Повний текст джерелаRoad applications such as traveller information, automatic emergency calls, freight management or electronic fee, collection require a onboard equipment (OBE) capable to offer a high available accurate position, even in unfriendly environments with low satellite visibility at low cost. Specifically in life critical applications, users demand from the OBEs accurate continuous positioning and information of the reliability of this position. This thesis presents a solution based on the fusion of Global Navigation Satellite Systems (GNSS) and inertial sensors (GNSS/INS), running an Extended Kalman Filter combined with an Interactive Multi-Model method (IMM-EKF). The solution developed in this work supplies continuous positioning in marketable conditions, and a meaningful trust level of the given solution. A set of tests performed in controlled and real scenarios proves the suitability of the proposed IMM-EKF implementation, as compared with low cost GNSS based solutions, dead reckoning systems and single model extended Kalman filter (SM-EKF) solutions.

Fekih, Hassen Wiem. "A ubiquitous navigation service on smartphones." Thesis, Lyon, 2020. http://www.theses.fr/2020LYSEI006.
Повний текст джерелаPedestrian navigation is a growing research field, which aims at developing services and applications that ensure the continuous positioning and navigation of people inside and outside covered areas (e.g. buildings). In this thesis, we propose a ubiquitous pedestrian navigation service based on user preferences and the most suitable efficient available positioning technology (e.g. WiFi, GNSS). Our main objective is to estimate continuously the position of a pedestrian carrying a smartphone equipped with a variety of technologies and sensors. First, we propose a novel positioning technology selection algorithm, called UCOSA for the complete ubiquitous navigation service in indoor and outdoor environments. UCOSA algorithm starts by inferring the need of a handover between the available positioning technologies on the overlapped coverage areas using fuzzy logic technique. If a handover process is required, a score is calculated for each captured Radio Frequency (RF) positioning technology. The score function consists of two parts: the first part represents the user preferences weights computed based on the Analytic Hierarchy Process (AHP). Whereas, the second part provides the user requirements (normalized values). UCOSA algorithm also integrates the Pedestrian Dead Reckoning (PDR) positioning technique through the navigation process to enhance the estimation of the smartphone's position. Second, we focus on the RSS fingerprinting positioning technique as it is the most widely used technique, which principle is to return the smartphone's position by comparing the real time recorded RSS values with the radiomap (i.e. a database of previous stored RSS values). Most of radiomap are organized in a grid, formed or Reference Point (RP): we propose a new design of radiomap which complements the grid with other RPs located at the center of gravity of each grid square. Third, we address the challenge of constructing a graph for a multi-floor building. We propose an algorithm that starts by creating the horizontal graph of each floor, separately, and then, adds vertical links between the different floors. Finally, we implement a novel algorithm, called SIONA that calculates and displays in a continuous manner the pathway between two distinct points being located indoor or outdoor. We conduct several real experiments inside the campus of the University of Passau in Germany to evaluate the performance of the proposed algorithms. They yield promising results in terms of continuity and accuracy (around 1.8 m indoor) of navigation service

Повний текст джерелаEffects of functioning transportation infrastructure are receiving more and more environmental and social concern nowadays. Nevertheless, preliminary corridor plans are usually developed on the basis of technical and economic criteria exclusively. By the time of environmental impact assessment (EIA), which succeeds, relocation is practically impossible and only preventative measures can be applied.
This paper proposes a GIS-based method of delimiting motorway corridor and integrating social, environmental and economic factors into the early stages of planning. Multiple criteria decision making (MCDM) techniques are used to assess all possible alternatives. GIS-held weighted shortest path algorithm enables to locate the corridor. The evaluation criteria are exemplary. They include nature conservation, buildings, forests and agricultural resources, and soils. Resulting evaluation surface is divided into a grid of cells, which are assigned suitability scores derived from all evaluation criteria. Subsequently, a set of adjacent cells connecting two pre-specified points is traced by the least-cost path algorithm. The best alternative has a lowest total value of suitability scores.
As a result, the proposed motorway corridor is routed from origin to destination. It is afterwards compared with an alternative derived by traditional planning procedures. Concluding remarks are that the location criteria need to be adjusted to meet construction
requirements as well as analysis process to be automated. Nevertheless, the geographic information system and the embedded shortest path algorithm proved to be well suited for preliminary corridor location analysis. Future research directions are sketched.

Повний текст джерелаTrots att föroreningar i luften är bland de största hoten mot mänsklig hälsa är den information som finns tillgänglig för allmänheten ofta både gles och inte tillräckligt noggrann eller uppdaterad. Till exempel finns det i hela Storstockholm endast mellan 5–10 luftkvalitetstationer som mäter föroreningar. Detta innebär att den data som finns tillgänglig är bra i närheten av mätutrustningen men kan skilja sig mycket enbart ett par kvarter bort. För att öka mängden information som är tillgänglig till allmänheten räcker inte längre enbart de stationära lösningarna som finns idag för att visa hur de rådande halterna av föroreningar står sig. Andra metoder måste införas, exempelvis genom att nyttja mobila mätningar från en plattform som kan röra sig fritt. GOEASY är ett projekt finansierat av den Europeiska Kommissionen, där Galileo, Europas nya navigationssystem används för att tillåta fler platsbaserade tjänster att äntra marknaden. Som en del av GOEASY projektet ingår evalueringen av potentialen i en applikation där användare samlar in data för att hjälpa individer med andningssvårigheter som astma. Denna avhandling presenterar valen till arkitekturen samt implementationen av en mobil plattform som en del av GOEASY. Lösningen använder sig av mobila luftkvalitetsensorer som kan monteras på en rad olika objekt som samlar data i realtid som görs tillgänglig för allmänheten. Resultatet är en mobil plattform och tillhörande Android applikation som med hjälp av luftkvalitetsensorer rapporterar halten av olika skadliga föroreningar tillsammans med platsinformation till en central server. Tack vare egenskaperna av de underliggande systemen som används, skapas en plattform som är mycket mer precis när det gäller positionering jämfört med liknande system som finns tillgängligt. Det resulterande systemet gör det möjligt för individer med andningssvårigheter att få tillgång till noggrannare samt mer uppdaterad information i större utsträckning än vad som för närvarande är tillgängligt. Systemet fyller även syftet med att demonstrera potentialen i den bakomliggande teknologin som en del av GOEASY.

Повний текст джерелаSince the devastating earthquakes of 1999, east of Istanbul, the submerged section of the North Anatolian Fault (NAF), in the Sea of Marmara (SoM) has been intensively monitored, mainly using land stations. Still, the micro-seismicity remains poorly understood. In addition, although the connection of the SoM with the hydrocarbon gas system from the Thrace Basin is now well established, along with the presence of widespread gas within the sedimentary layers, the role of gas on seismicity is still not recognized.Here, we have analyzed Ocean Bottom Seismometer (OBS) data from two deployments (April-July 2011 and September-November 2014) in the western SoM. Based on a high-resolution, 3D-velocity model, and on non-linear methods (NonLinLoc), our location results show that a large part of the micro-seismicity occurs at shallow depths (< 6 a 8 km): along secondary faults, inherited from the complex history of the North-Anatolian shear zone; or within the uppermost (< 1 km), gas-rich, sediment layers. Part of this ultra-shallow seismicity is likely triggered by the deep earthquakes of intermediate magnitude (Ml > 4.5) that frequently occur along the western segments of the MMF.In addition, OBSs also record at least two families of short duration (<1 sec) events (SDEs): 1) “background SDEs” occurring on a permanent, at a rate of a few tens of SDEs/day, resulting from many possible, local causes, e. g.: degassing from the seafloor, biological activity near the seabed, bioturbation, etc; 2) “swarmed SDEs”, among which some are recorded also on the hydrophone, and characterized by a periodicity of ~ 1.8 seconds. The causes of these SDEs still remain to be determined (among which: anthropogenic causes, marine mammals, gas emissions, regional seismicity, tremors from the MMF, etc)

Повний текст джерелаAo longo dos anos tem-se verificado um aumento quase exponencial no que toca à utilização de novas tecnologias em vários sectores. Estas tecnologias têm como objetivo principal, melhorar ou facilitar o quotidiano. O presente estudo vai incidir sobre uma destas tecnologias utilizada dentro de um tema que tem sido muito falado nos últimos anos, a utilização de dados pessoais de um grupo de indvíduos para identificar certos tipos de comportamentos. Mais concretamente, tem como objetivo utilizar os dados de GPS, guardados nas respectivas contas Google de nove voluntários, de modo a identificar os locais que estes mais frequentam - Pontos de Interesse. Os dados são utilizados também para identificar as trajectórias percorridas mais vezes por cada um dos voluntários. Foi realizado um estudo com uma amostra de 9 participantes, enviando-lhes os respectivos mapas com POI e trajectórias obtendo assim a validação dos mesmos. Desta forma foi possível concluir que que a melhor forma de identificar POI tem como base a utilização de clusters diários utilizando DBSCAN. Para o caso das trajectórias, o método Snap-to-Road foi o que originou melhores resultados. Verificou-se que foi possível responder ao problema inicial, desta forma, foi encontrado um método que identifica a maior parte dos POI com sucesso, bem como algumas trajetórias. Com base neste trabalho, existe uma oportunidade para futuramente melhorar alguns dos algoritmos e processos que possuem algumas limitações de modo a desenvolver soluções mais eficazes.

Assisted-GPS(A-GPS)technology overcomes the downsides of the conventional GPS solution, and achieves high location accuracy at reasonable cost. The assistance to the mobile phone trying to determine its own location comes from the network over the air-interface. What makes this technology work so well is that the wireless network, using its own GPS receivers, as well as an estimate of the mobile’s location down to cell/sector, can predict with great accuracy the GPS signal the handset will receive and convey that information to the mobile. With this assistance the size of the search space is greatly reduced, and the time-to-first-fix(TTFF)shortened from minutes to a second or less. GPS receivers are sometimes unreliable or unusable under circumstances such as urban canyons. It is because tall buildings block (or mask) the transmitted signals that number of satellites in view are often not enough for the receiver to obtain a position solution. A-GPS receivers enhance the sensitivity of receivers in detecting GPS signals. However, improvements of hardware technology are somewhat limited. The author suggests that by modifying the A-GPS server system software, the receivers can still work normally under certain adverse environments that they used to fail to perform. The main idea is that, when the number of satellites in view are not enough, the A-GPS server sends calculated ranges between serving base station and the assisting satellites, and therefore helps to locate users. Performance of the proposed method as analyzed with numerical simulations is rather promising and reasonably feasible.

The number of customers of coffee shop chains has grown steadily in recent years that cause the market size as well as the total consumption value increase rapidly and continuously. The competition among the chain coffee stores get even worse under the traditional profit oriented management style. In such case, it is crucial to make the correct decisions when selecting the coffee shop locations as well as making operation strategies in opening new coffee shops. Traditionally, it takes a great amount of time and human resources in collecting relevant information, conducting field visits as well as site evaluations when making coffee shop site selections. One seldom considers complex factors of site evaluation or field analyzing in selecting the location of new coffee shop. Hence, it will be one of the major contributions if one can find a mechanism in analyzing the site selection as well as profit evaluation to help the investors to produce better profit and to improve the chance of success. The goal of this thesis is to provide recommendations to improve the success rate of chain coffee shop site selection strategy. Based on the coffee market leaders’ success experiences in formulating the site selection strategies, we analyzed the correlation coefficients of the population as well as economy activities in order to identify the key factors in successful site selection strategies. We also used data mining techniques to construct the classification models of successful site selection. In addition, we analyzed and evaluated competition relations between the two leading chain coffee brands using the geographic information systems to obtain appropriate recommendations in new site selections. The shop rental information of Taipei City was used to explore and to evaluate the models recommended in our mechanism. The experimental results showed that the prediction through the classification models for site selections can achieve 70% of success rate. This indicates our mechanism effectively improve the successful rate of site selections. Moreover, the experimental results also show that the spatial analysis of site selections between the competitors is helpful in providing appropriate site selection strategies.

The power transmission systems in Taiwan are mainly of overhead lines, most of which are located in the suburbs or places that are not very populated. Consequently, they are vulnerable to impact of the natural environment, which may result in outage due to the device fault in the transmission line. If it is not equipped with a fault detection system and device, it won’t be able to locate the fault and get the related information effectively. It doesn’t only waste manpower and resources, but also affect the recovery and power supply schedule, which may even pose great impact to the economic and industrial development of an area and bring inconvenience to the communities’ source of livelihood. Moreover, for the installed fault detection system and device, the primary issue is about how to make full use of its accuracy and reliability. Considering the cost, it is impossible to set up the fault detectors intensively in each transmission line to provide the fault message, which doesn’t only equate to a high setup cost, but also add to the maintenance cost. Thus, the fault detectors may be set up on both ends of the transmission line, which can then combine with the fiber-optical communication line/computer’s computation function/signal processing unit. Moreover, it makes use of a GPS locator to send the fault location to the travelling wave message of the two terminals for computation processing, which will indicate the location and the related information of the transmission line fault. In this way,it can effectively provide the maintenance personnel with the correct fault location, so the fault can be fixed within the shortest time. However, when the transmission line is outdoors with long distance, it will be affected by a lot of factors such as impedance of conducting wire, seasonal weather and temperature and accuracy of the components on the detector. All these may result in high error percentage of the fault location, bring much more troubles to the maintenance personnel, and finally delay the repair schedule. This paper will explore the positioning accuracy of the fault locator on the fault of the power transmission device based on the fault data generated by the GPS transmission line fault locator being used by Heping Thermal Power Plant currently. Moreover, it applies SVM data analysis theory to collect and classify the correct and stable fault data with reference values, so as to calculate and discuss the signal error correction value. Furthermore, it improves and adjusts the parameters of the fault locator, so the positioning date of the transmission line fault will be more accurate, detailed and correct. In this way, it allows the maintenance personnel to determine the fault location effectively and quickly, so they can fix the problem immediately, which in turn reduces the losses caused by power supply interruption.

Повний текст джерелаThe huge and rapid advancement in science and technology in this globe such as GIS and Satellite digital mapping makes it a must for developing countries to catch-up and utilize it. Usage of GIS-technology is essential, as it is becoming one of the better and faster tools to manage resources and helps in the decision support process .A GIS uses electronic mapping technology in producing interactive multi-layer maps so that queries are set to find optimal solutions for problems. It combines spatial and non-spatial data to construct visualized information that can be easily analyzed by decision makers.Using GIS technology is a powerful tool to help in planning since the digital map could be used in defining best positions for different purposes such as banks, ATMs, new schools, restaurant, etc. The paper discusses the criteria used in the spatial analysis, and also, reports on the success of the resultant GIS analysis to suggest proper locations for ATM’s.

Повний текст джерелаIdentifying spatial and temporal patterns of disease occurrence by mapping the residential locations of affected people can provide information that informs response by public health practitioners and improves understanding in epidemiological research. A common method of locating patients at the individual level is geocoding residential addresses stored in electronic medical records (EMRs) using address matching procedures in a geographic information system (GIS). While the process of geocoding is becoming more common in public health studies, few researchers take the time to examine the effects of using different address databases on match rate and positional accuracy of the geocoded results. This research examined and compared accuracy and match rate resulting from four commonly-used geocoding databases applied to sample of 59,341 subjects residing in and around Marion County/ Indianapolis, IN. The results are intended to inform researchers on the benefits and downsides to their selection of a database to geocode patient addresses in EMRs.
