▼ In recent years, there has been rising interest in commercial applications of Unmanned Air Vehicles (UAVs). Examples of their usage include aerial photography, infrastructure inspection and emergency first response. For widespread commercial adoption of these applications to occur, UAV navigation must be made safe and reliable. In open-sky environments, Global Positioning System (GPS) receivers are most commonly used to provide accurate and globally referenced positioning for UAVs. However, many applications, such as consumer product delivery, require UAVs to operate in densely populated urban environments. In these environments, buildings and structures reflect and block GPS signals, leading to multipath and low satellite visibility. These factors create GPS-challenged environments that result in large errors in UAV positioning or make GPS unavailable. To improve urban GPS, one approach uses environment modeling such as 3D city models to mitigate the effects of multipath and NLOS errors. Others pair GPS with odometry measurements from relative positioning sensors, such as Light Detection and Ranging (LiDAR) sensors. LiDAR-based odometry provides an accurate relative navigation solution in GPS-challenged environments, but requires distinguishable features in the surrounding environment and is susceptible to drift and biases. As a result, there is a need for sensor fusion techniques that can provide reliable and robust positioning in urban environments. In this thesis, we apply a Simultaneous Localization and Mapping (SLAM) approach to fuse GPS pseudorange measurements with LiDAR point clouds and 3D building footprint data of the existing region, for UAV trajectory estimation and environment mapping. Our approach consists of three main aspects: graphical modeling, map-based processing, and inference. First, we use a probabilistic graph, specifically a directed acyclic graph, to model the trajectory of a UAV. Nodes in the graph represent states of the UAV or GPS satellites; while edges represent relations between states created by sensor measurements. We then use the graph to structure our environment maps. We represent our environment in two mapping formats: a point cloud map and an urban building map. The point cloud map is formulated by anchoring each collected LiDAR point cloud with their respective state. The result is a large point cloud collected throughout the trajectory of the UAV. The urban building map is a geometric representation of the large scale structures in the environment. It is first initialized with available sources of 3D building model data for the navigating region. In this work, we use Champaign building footprint data from the State of Illinois data portal. We then run plane fitting algorithms on the collected point clouds at each state to update the urban building map. As the UAV navigates, the graph is populated by additional nodes and corresponding LiDAR measurements, allowing for SLAM of the environment. Next, we apply the formulated maps in two ways: mitigation of errors… Advisors/Committee Members: Gao, Grace X (advisor).

▼ Space-borne GPS receivers designed for nano-satellites are faced with various challenges. This research is undertaken to address the problems of inefficiency and high-costs associated with space-borne GPS receivers. The problem of inefficiency relates to poor performances of the GPS receiver in terms of the algorithmic models, execution speed, memory usage and errors proness. The problem of high-costs relates to the spacegrade hardware cost, implementation complexity, development time, as well as the manufacturing, production and the testing processes involved. The research objectives are to i) establish an efficient high-dynamics software-defined GPS receiver, ii) demonstrate a firmware approach and then iii) postulate a low-cost hardware implementation roadmap. The research methodology employed to address the problems and to attain the objectives is based-on using Matlab computing platform to i) implement a software-defined GPS receiver using free open-source GPS receiver algorithms, ii) further develop the software GPS receiver and lastly iii) convert the improved GPS receiver algorithms to firmware. The GPS receiver was successfully implemented in Matlab floating-point algorithms with a ±100kHz Doppler search bins and was used to post-process a pre-captured real GPS L1 C/A signal dataset. The pre-captured GPS signal was acquired, tracked, decoded and post-processed to extract the navigation message; use to compute the GPS receiver position, UTC date and time. Attempt to convert the entire Matlab floating-point GPS receiver algorithms to equivalent VHDL implementations failed; however, three of the Matlab floating-point algorithms (check_t.m, deg2dms.m and findUtmZone.m), were successfully converted to equivalent fixed-point formats in Matlab, Simulink and finally VHDL. These three algorithms, now created and optimised to fixed-point formats (efficient and enable implementation unto a low-cost microcontroller), set the basis for the firmware implementation. They were simulated and verified in Matlab, Simulink and VHDL using the Matlab HDL Coder workflow. Altera Quartus II software was then used to compile (synthesise, place & route and generate programming files) the three converted generic VHDL algorithms to embedded firmware, suitable for a FPGA programming. The Matlab HDL Coder workflow used in this research is feasible and can be used to accurately design and implement an improved GPS receiver and furthermore achieve it in three equivalent algorithms. This conclusion was drawn and the proposed recommendations are to address the conversion issues in the other Matlab floating-point GPS receiver algorithms that failed in the conversion process and to further develop and implement the GPS receiver as a fully functional unit, based-on the Xilinx space-grade, radiation hardened and low-cost Virtex 5QV FPGA.

▼ Small unmanned aerial system (UAS) and smart missile and munitions platforms rely on GPS for accurate position, velocity and time (PVT) information. These platforms have significant aerodynamic and space constraints that require innovative conformal GPS antenna solutions. Microstrip antennas are well suited for this type of application due to their inherently low profile package and ability to conform to the shape of a given platform. Since their inception over four decades ago, a significant body of literature has been compiled on the analysis of microstrip antennas. However, most of that research has focused on the development of analytical models and techniques for reducing the size, extending the bandwidth and achieving circular polarization for planar embodiments. Conformal microstrip antennas, on the other hand, have a much more limited body of literature spanning the last three decades. The conformal microstrip antenna literature has focused on the efficient analysis of the singly curved conformal microstrip antenna (SC-CMA), with most published results for single linear polarization and microstrip antennas that conform to cylinders with electrically large radii (i.e., kb > 1, where k is the free space propagation constant and b is the bend radius of the patch metal). This research expands the knowledge of the SC-CMA by investigating the use of a cylindrical rectangular microstrip antenna (CRMA) mounted on an electrically small radius (i.e., kb < 1) cylinder for the purpose of radiating a circularly polarized field. A full-wave 3D analysis of the CRMA TM01 (axial) and TM10 (circumferential) modes was conducted in Ansys HFSS. It was discovered that the input impedance bandwidth of the CRMA TM01 mode more than doubled, while that of the TM10 mode remained virtually unchanged, as the cylinder radius was decreased from infinite, planar, to approximately 0.15 free space wavelengths. In addition, the resonant frequency of the CRMA TM10 mode steadily increased by 3 to 5 percent, while that of the TM01 mode remained virtually unchanged, as the cylinder radius was decreased to 0.15 free space wavelengths. The performance trends of the CRMA as a function of patch metal bend radius were incorporated into the planar microstrip transmission line model (TLM) through modification of the radiating slot normalized length and width. The newly developed CRMA TLM and Ansys HFSS models were validated via measurement of a microstrip line edge fed CRMA. The input impedance bandwidth and resonant frequency of the models differed by less than 0.25% and 3.0%, respectively, from the measured results. The validated CRMA TLM and Ansys HFSS models were used to successfully design a circularly polarized CRMA GPS antenna that met most of the requirements for a small munitions application.

▼ The application of microtechnology devices (Global Positioning Systems (GPS) and integrated triaxial accelerometers) has become common practice in team sports due to the ability to provide objective information on the physiological requirements of match-play and training. The aims of this thesis were to review the literature examining the application of GPS technology in team sports; and utilise novel applications of GPS and integrated accelerometer technology in rugby league to quantify pre-season training loads, match collision forces and the energetic demands of match-play; as well as to examine positional group differences. GPS was used to measure training demands, video and accelerometer data were utilised to quantify collision forces, and energetic demands were estimated via a time-motion model from accelerometer data. The systematic review highlighted inconsistencies in movement demand classifications and the difficulties encountered in quantifying collisions/impacts. The four studies identified marked differences in positional specific demands throughout training and match-play. Pre-season training differences in various external load parameters were observed in drills where players trained within specific positions, whereas minimal differences were evident between positional groups within conditioning, generic skill and speed/agility drills. Outside backs as full-match players expended the most energy per match from increased running demands, but experienced the lowest collision demands, the majority of which arose from attacking play. Adjustables, also full-match players (apart from hookers who interchange), experienced elevated energy expenditure from increased anaerobic demands, however sustained reduced collision demands. As interchange players, hit-up and wide-running forwards expended the least energy (due to decreased running demands), but endured increased collision demands. Indeed, hit-up forwards performed five times more tackles per minute than outside backs and twice as many hit-ups per minute as adjustables. However, despite differences in total energy expenditure, the anaerobic work performed by the outside backs and wide-running forwards at high speed equates to a similar load on the metabolic system as the accelerated running patterns of adjustables and hit-up forwards. The differential positional demands identified indicate that position-specific conditioning drills are required to replicate the energetic and collision demands of match-play.

▼ The integrity of positioning systems has become an increasingly important requirement for location-based Intelligent Transports Systems (ITS). The navigation systems, such as Global Positioning System (GPS), used in ITS cannot provide the high quality positioning information required by most services, due to the various type of errors from GPS sensor, such as signal outage, and atmospheric effects, all of which are difficult to measure, or from the map matching process. Consequently, an error in the positioning information or map matching process may lead to inaccurate determination of a vehicle’s location. Thus, the integrity is require when measuring both vehicle’s positioning and other related information such as speed, to locate the vehicle in the correct road segment, and avoid errors. The integrity algorithm for the navigation system should include a guarantee that the systems do not produce misleading or faulty information; as this may lead to a significant error arising in the ITS services. Hence, to achieve the integrity requirement a navigation system should have a robust mechanism, to notify the user of any potential errors in the navigation information. The main aim of this research is to develop a robust and reliable mechanism to support the positioning requirement of ITS services. This can be achieved by developing a high integrity GPS monitoring algorithm with the consideration of speed, based on the concept of context-awareness which can be applied with real time ITS services to adapt changes in the integrity status of the navigation system. Context-aware architecture is designed to collect contextual information about the vehicle, including location, speed and heading, reasoning about its integrity and reactions based on the information acquired. In this research, three phases of integrity checks are developed. These are, (i) positioning integrity, (ii) speed integrity, and (iii) map matching integrity. Each phase uses different techniques to examine the consistency of the GPS information. A receiver autonomous integrity monitoring (RAIM) algorithm is used to measure the quality of the GPS positioning data. GPS Doppler information is used to check the integrity of vehicle’s speed, adding a new layer of integrity and improving the performance of the map matching process. The final phase in the integrity algorithm is intended to verify the integrity of the map matching process. In this phase, fuzzy logic is also used to measure the integrity level, which guarantees the validity and integrity of the map matching results. This algorithm is implemented successfully, examined using real field data. In addition, a true reference vehicle is used to determine the reliability and validity of the output. The results show that the new integrity algorithm has the capability to support a various types of location-based ITS services.

▼ The precise positioning applications have long been carried out using dual frequency carrier phase and code observables from the Global Positioning System (GPS). The carrier phase observables are very precise in comparison to the code ones, the reason phase observables play an important role in precise geodetic applications. The carrier phase observables can have precision of about 3 millimeters. However the precision of the estimated parameter of interest, say the receiver position, depends upon the correct resolution of integer ambiguities present in the carrier phase observables. Significant contributions have been made in the last couple of decades towards integer ambiguity estimation to make precise positioning applications possible, using GPS carrier phase and code data from geodetic receivers.Precise positioning applications have been successful in the past, but at the cost of time taken to correctly resolve the integer ambiguities. This delay in integer ambiguity estimation is caused due to the presence of various propagation and hardware related effects present in the observables of GPS or in that case, any other Global Navigation System. The propagation errors related to the atmosphere are significant for medium to long baseline lengths. Among the atmospheric errors, the ionosphere is found to have profound effect on the process of integer ambiguity estimation. With the aid of permanent reference networks, corrections for ionosphere could be interpolated and further transferred to the user with an aim to enhance users ambiguity resolution and fulfill the aim of an efficient and reliable precise positioning.With the advancement of Global Navigation Satellite Systems (GNSS) several of the limiting factors which degrade users ambiguity resolution are seen to be met. The relatively poor precision of the code data in comparison to the phase data, is foreseen to improve for third GPS frequency, also called as GPS L5. Also most of the frequencies on Galileo system would have improved code precision.The ionosphere which has been a major blockade in fast integer ambiguity resolution, for long baseline lengths, would also benefit in a multi-frequency, multi-GNSS scenario. Since a GNSS model, in which the ionosphere is considered unknown and estimated, gains strength with addition of a frequency. The addition of L5 on GPS and availability of up to four frequencies on Galileo system would strengthen the GNSS model which would be beneficial when ionosphere is parameterized for estimation. This study aims at understanding the above mentioned and other possible benefits of the future GPS and Galileo system.The benefits that the future GPS and Galileo can bring to precise applications can be evaluated in terms of correct resolution of integer ambiguities present in the carrier phase data and further by understanding the contribution of the ambiguity resolution towards improvement of fixed-precision of the parameters of interest. The correct resolution of ambiguities was judged by computing the probability of correct…

▼ As respostas fisiológicas dos jogos com campo reduzido (JCRs) têm sido amplamente demonstradas. Em relação às características cinemáticas de deslocamento, os estudos têm demonstrado que os JCRs não simulam as demandas de esforço em alta intensidade e em sprints exigidas durante partidas de futebol. Dessa forma, existe a necessidade de propor alternativas para aumentar a demanda física durante JCRs. Sendo assim, os objetivos do estudo foram comparar as respostas fisiológicas agudas e as características cinemáticas de deslocamento entre dois modelos de JCRs (JCR convencional [JCRcon] e JCR modificado [JCRmod]) com as respostas registradas durante um jogo de futebol de campo e relacioná-las com a capacidade física e com o nível maturacional dos atletas. Métodos: A amostra foi composta por 15 jogadores de futebol da categoria sub-15 (14,3 ± 0,5 anos; 55,6 ± 7,1 kg; 1,66 ± 0,1 m). Os atletas realizaram Yo-Yo Intermittent Recovery Test Level 1 (YYIRTL1) e o teste de Repeated Sprint Ability (RSATeste), além de quatro sessões de JCRs (2 JCRcon e 2 JCRmod) e um jogo coletivo. Os JCRs foram realizados em dois formatos 3 vs 3 com mini gol e 7 vs 7 com gol com dimensões oficiais e com goleiros. Ambos os formatos foram realizados em 4 séries com duração de 4 min cada, com 3 min de recuperação passiva entre as séries. Durante os JCRmod os atletas realizaram quatro sprints em cada série, os quais foram escolhidos através de sorteio, com o intervalo entre cada sprint superior a 20 s. Frequência cardíaca (FC), concentração sanguínea de lactato ([La]) e percepção subjetiva de esforço (PSE) foram monitoradas em todas as sessões de treinamento. As características cinemáticas de deslocamento foram analisadas através de um Global Positioning System (GPS) com frequência de amostragem de 15 Hz. Resultados: A distância total percorrida e a distância percorrida em alta intensidade e em sprints foram significantemente superiores (P <0,05) nos JCRs 3 vs 3sp e 7 vs 7sp em relação aos JCRs 3 vs 3 e 7 vs 7. A distância percorrida em alta intensidade e o tempo despendido em sprint foram significantemente maiores (P <0,05) nos JCRmod e no jogo em relação ao JCRcon em ambos os formatos (3 vs 3 e 7 vs 7). Não houve diferença significante nas respostas fisiológicas entre os JCRs 3 vs 3 e 3 vs 3sp. Entretanto, a intensidade durante o JCR 7 vs 7sp foi significativamente superior (P <0,05) ao JCR 7 vs 7. Não houve correlações significantes (P >0,05) entre os testes de desempenho e as características cinemáticas durante as sessões de treinamento, no entanto, houve correlação positiva (P <0,05) entre a razão da idade esquelética pela idade cronológica (IE/IC) e a distância percorrida em sprint (>18,1 km.h-1) durante os JCRs 3 vs 3sp, 7 vs 7 e durante o jogo (r = 0,596; r = 0,605; r = 0,686, respectivamente) e correlação com a distância percorrida em alta intensidade (>13,1 km.h-1) no JCR 3 vs 3sp (r = 0,620). Dessa forma, conclui-se que a modificação na estrutura dos JCRs (JCRmod) ocasionou em uma maior demanda física nos atletas durante os JCRs (3 vs 3sp e… Advisors/Committee Members: Fábio Yuzo Nakamura ., Fabiana Andrade Machado, Valmor Alberto Augusto Tricoli.

▼ Travel surveys are increasingly taking advantage of global positioning system (GPS) data offering precise and objective route and time observations whilst potentially reducing response burden. However, there are still several open issues concerning the automated post-processing of these large datasets. Without a reliable post-processing, GPS-based studies require either a considerable amount of manual analysis, leading to costly surveys or extensive prompted-recall interviews with the respondents. As part of this thesis a travel diary study was conducted in the Greater Zurich Area. 150 participants carried dedicated GPS devices for up to one week and corrected their diaries in a web-based prompted recall tool. Using the resulting data set, the existing POSition DAta Processing framework was extended by a trip purpose module. Random forests, a machine learning technique, is used for classification. For trip purpose a share of correct predictions between 80 and 85 % is achieved for different setups. High variability in accuracy between persons is observed. Hence, personalisation strategies are tested. It is shown that the classifier is improved if it is learned on data that includes some of the participant?s annotations (median accuracy + 5.5 %). The updated processing tool, and also lessons learned from the GPS survey in Zurich are tested in the PEACOX project, a joint project with many partners where a smartphone cross modal trip planner was developed that encourages ecological friendly behaviour. GPS and accelerometer time series for 33 study participants in Vienna and Dublin are available for analysis; these were tracked simultaneously with smartphones and dedicated devices for 8 weeks. Therefore, further insight into the usefulness of smartphones and dedicated GPS devices for collecting current travel survey data is gained. Meaningful diaries can be extracted from both data sources. However, if high resolution data is needed, results suggest that dedicated GPS devices are still relevant; they have no battery issues, meaning that more data is recorded and that data quality is more stable. High resolution data is particularly interesting to observe taken routes. Two potential applications are shown here: route choice models are estimated for all travel modes (public transport, car, bicycle and walking) and parking search is shown to be hard to identify in our data.

▼ In transport research, discrete choice models are used to represent many aspects of travel behaviour. They model the choice of a decision-maker who is confronted with a set of discrete alternatives and chooses the alternative that maximises his or her utility. Discrete choice models give analysts and political decision-makers the opportunity to asses the impacts of infrastructure schemes and transportation policies in different scenarios with relatively low effort. Considering the scale of these projects and their significance for society, a realistic representation of travel behavior is crucial. To achieve more realistic travel behaviour models, researchers recently focussed – amongst others – on two major issues: a more accurate representation of the actual behaviour and the available alternatives by the means of high-resolution data and the treatment of similarities between alternatives. The high-resolution observations are obtained from GPS surveys which offer several advantages. Modellers benefit from more accurate and reliable information while the participants’ burden is reduced substantially as long as the GPS recording is not combined with time-consuming questioning. However, the increasing spatial resolution leads to new challenges, in particular regarding the treatment of similarities. Choice models estimated on high-resolution data are characterised by a large number of alternatives and complex similarity structures due to an increasing number of alternatives that differ only slightly from each other. Thus, state-ofthe- art models have to be able to handle large choice sets and at the same time be flexible and able to accommodate various similarity structures. In this dissertation, GPS observations for 32,000 person-days recorded by inhabitants of the Swiss cities of Zurich, Winterthur, and Geneva are processed with the aim to estimate car route choice models with an appropriate treatment of the similarities between the alternatives. The processing included filtering and cleaning the GPS records, deriving trips, activities and modes, and identifying the chosen routes by matching the car trips to a high-resolution network. Then, the choice sets were generated. The subsequently estimated route choice models tested different adjustment terms to account for route overlap. During the entire process, interesting lessons were learned about the new challenges introduced by the high level of spatial detail. These lessons are of vital importance for all analysts who want to model travel behaviour with this new generation of individual travel behaviour observations.

This research investigates the value placed by travelers on HOT lanes because of improve- ments in travel time reliability. This value depends on how the travelers regard a route with predictable travel times (or small travel time variability) in comparison to another with unpredictable travel times (or high travel time variability). For this purpose, com- muters were recruited and equipped with Global Positioning System (GPS) devices and instructed to commute for two weeks on each of three plausible alternatives between their home in the western suburbs of Minneapolis eastbound to work in downtown or the Univer- sity of Minnesota: I-394 HOT lanes, I-394 General Purpose lanes (untolled), and signalized arterials close to the I-394 corridor. They were then given the opportunity to travel on their preferred route after experiencing each alternative. This revealed preference data was then analyzed using mixed logit route choice models. Three measures of reliability were explored and incorporated in the estimation of the models: standard deviation (a classical measure in the research literature); shortened right range (typically found in departure time choice models); and interquartile range (75th - 25th percentile). Each of these measures repre- sents distinct ways about how travelers deal with dierent sections of reliability. In all the models, it was found that reliability was valued highly (and statistically signicantly), but dierently according to how it was dened. The estimated value of reliability in each of the models indicates that commuters are willing to pay a fee for a reliable route depending on how they value their reliability savings. Furthermore, a meta-analysis is performed in order to explain the dierences across valuation ratio estimates across studies. The results indi- cate dierences are signicant across regions, choice dimension (e.g. mode choice), travel time unit (e.g. data collected at AM or PM), and year of study.

▼ Environmental problems are discouraging. Extensive and growing media consumption in the U.S. may be one of a few reasons. Communication constructs how people experience and understand nature, and corporate ownership of media influences the content (Beder, 2004). What does this discouragement look like in the news? Nature is often made the culprit that impinges on people identified as consumers. Added environmental responsibility for the “green” consumer can overwhelm them, and negative connotations associated with environmentalist suggest people avoid that label. And the odds seem to be in nature’s favor, when the individual is pitted against such forces as El Niño, and global warming. Technology, often the savior, produces additional conflict, problems, and cost. War metaphors and rhetoric in the fight over resources raises concerns over other uses. Polls show U.S. Americans becoming more fearful of environmental problems, but not changing their consumption patterns to help solve the problems. Environmental injustices can result from communication practices, even war and violence. All of these aspects point to power—who has authority, how they use it in dominant discourses, and what responses it produces. It is a social fact that people are discouraged about the environment. Critical-cultural and media studies, provide ideas to address social and environmental problems through communication and provide three paths for understanding; critical theory addresses power and domination; symbolic interaction addresses meaning making from social interaction; and rhetoric, narrative and discourse address how ideas are used in stories to persuade people. These fields emerge from the work of the Chicago school on the interactions of society and mass media, and the Frankfurt school (with roots in Marxism) on the legitimacy which commercial media provide those in power that maintains inequalities and injustice. Critical analysis of media stories that relate to the environment, expose a bigger world than that described by those in power. Challenging that discourse can offer justice to those with little to no power or voice. It can also propose alternatives to alleviate inequality. The Chicago school’s sense of hope adds to this, in trying to make the world better by research on how the world is represented, and how power is used to dominate people and nature. Theory of environmental communication (Milstein, 2009) bridges three areas: the material-symbolic of real problems communicated through language; the mediated human-nature relationship that represents nature in particular ways; and applied activist theory which exposes problematic representations and offers better alternatives. Nature and environment are defined as symbolically complex ideas; nature, most often as all of the earth and beyond, but not including humans and their creations; whereas environment is seen as the surroundings that usually includes the creations of humans. Humans not acting as part of nature are a key piece of the problem and points to… Advisors/Committee Members: Denzin, Norman K. (advisor), Denzin, Norman K. (Committee Chair), Nerone, John C.

▼ Precise real-time GPS orbit at a high rate is required for a number of applications, including real-time Precise Point Positioning (PPP), long range RTK and weather forecasts. To support these applications, the International GNSS Service (IGS) has developed a precise orbital service. At present, users may take advantage of the predicted part of the IGS ultra-rapid orbit for real-time and near real-time applications. Unfortunately, however the data rate of such precise orbits is usually limited to 15 minutes. In addition, the precision of the predicted part of the IGS ultrarapid orbit is limited to about 10 cm. for the 24-hour predicted part, which may not be sufficient for the above applications, This research proposes algorithms for interpolation and prediction methods that are intended to reduce the effect of such limitations.This research examines the performance of four interpolation methods for IGS precise GPS orbits, nameley Lagrange, Newton Divided Difference, Bernese Polynomial, Cubic Spline and Trigonometric Interpolation. In addition, a comparison between this research and earlier studies were conducted. A new approach that utilizes the residuals between the broadcast and precise ephemeris to generate a high-density precise ephemeris is also introduced in this research.A three-step neural network-based model is then developed in this research to generate a 6-hour predicted orbital arc. First, an initial predicted orbit is generated by extrapolating a concentrated group of previous precise ephemeris for 5 days. GPS observations for 35 globally distributed tracking stations, corresponding to the 24-hour period preceding the predicted part, are then utilized within the Bernese software to further enhance the predicted orbit. FInally, the predicted orbit is refined by implementing a modular - three-layer feed-forward back-propagation neural network. A comparison is made between our predicted orbit and the IGS ultra-rapid orbit to verify the efficiency of the newly developed neural network-based model. It is shown that the newly developed neural network-based model improved the orbit prediction by 47%, 22% and 37% for three randomly selected satellites from Blocks IIA, IIR and IIR-M respectively.

▼ Community mobility (CM) is an important instrumental activity of daily living associated with quality of life and independence. Measuring the CM of older adults, particularly those with gait disorders such as Parkinson’s disease (PD), is an important way to understand how to help people maintain mobility in the real life setting. CM is measured using self-report measures and emergent technologies, such as wearable Global Positioning System (GPS) sensors. However, the measurement properties of most available assessments have not been compared within a PD population to determine their appropriateness and identify any feasibility issues. The primary objective of this project was to compare a novel instrumented measure (Wireless Isoinertial Measurement unit with GPS; WIMU-GPS) with a self-report diary and the Life Space Assessment (LSA). To accomplish this aim, a review of literature was first conducted to show that the validity and reliability between mobility measures were seldom assessed in existing comparison studies. Then, seventy people with early to mid-stage PD (67.4 ± 6.5 years, 67.1% men) wore the WIMU-GPS and completed the self-report diaries and LSA for a 14 day period. Moderate agreements were observed between WIMuGPS and diary for trip frequency and duration (Intraclass correlation coefficient [ICC] = 0.71, 95% CI = 0.51 to 0.82; 0.67, 95% CI = 0.42 to 0.82, respectively). Disagreement between these two measures was higher for duration, particularly among individuals who regularly worked or volunteered. Convergent validity and good reliability was attained for trip frequency (Spearman correlation coefficient [rs] = 0.69, 95% CI = 0.52 to 0.81; ICC = 0.714, 95% CI = 0.51 to 0.82) and duration outside (rs = 0.43, 95% CI = 0.18 to 0.62; ICC = 0.674, 95% CI = 0.42 to 0.82) measured by the WIMU-GPS and diary. However, convergent validity was not observed between WIMU-GPS recordings and LSA reported life space size (rs = 0.39, 95% CI = 0.14 to 0.60). The LSA exhibited ceiling effects and discrimination issues. It should be avoided as a CM measure when it is feasible to use the WIMU-GPS and diary instead. The secondary objective was to determine the utility and feasibly of using WIMU-GPS to quantify different dimensions of CM in people with PD (PwP). Using a subset of participants, it was first determined that sampling error was minimized in non-discrete continuous outcomes, such as “time outside” and “area size”, when daily WIMU-GPS recordings lasted at least 600 minutes. A shorter recording minimum of at least 500 minutes per day was also suitable for discrete outcomes, such as “trip count” and “hotspot count”. The sample size precluded the determination of the optimal number of days of recording. However, data from at least seven distinct days of recording is required to capture the natural fluctuations in CM between days of the week. From a practical standpoint, a minimum of seven distinct recording days were best attained if the WIMU-GPS was worn for at least eight days. Next, the new minimum GPS recording…

A organização do território está intimamente relacionada com a evolução dos transportes. O sector dos transportes é transversal a toda a economia. No contexto de instabilidade política e económica, que se vive actualmente, é crucial para qualquer organização possuir meios e técnicas capazes de responder às exigências do mercado. Nas últimas décadas ocorreram fortes alterações tecnológicas no sector dos transportes, que se deveram à crescente necessidade das empresas terem um maior controlo da sua actividade, não só agravada pelo aumento dos custos de combustível mas também pelo aumento da concorrência no sector. Os sistemas de gestão de frotas, aliados às novas tecnologias de informação e comunicação, (GPS, GPRS e ligações de banda larga mais fiáveis), revelaram-se ferramentas de gestão indispensáveis no controlo da actividade das empresas. Estas ferramentas de gestão permitem às empresas ter uma visão mais realista de todas as operações realizadas no terreno, na medida que podem acompanhar todos os acontecimentos em tempo real e ter acesso a todos os detalhes de cada viagem, percursos executados pelos operadores, bem como identificar os pontos críticos da actividade. Deste modo, o responsável pela gestão de frotas de uma empresa consegue identificar se os operadores cumpriram ou não as tarefas que lhe foram atribuídas, se respeitaram as horas permitidas de condução, os limites de velocidade, etc. No mercado existem sistemas que, além de permitirem identificar a localização do veículo ou carga, facultam informações adicionais, nomeadamente sobre as condições ou estado do veículo (cor, marca, chapa de matrícula, nível de combustível, data da inspecção, avarias, estado dos pneus, número de acidentes) e do condutor (carta de condução). Por outro lado, os sistemas de gestão de frotas, não só permitem às empresas uma melhor gestão, controlo e planeamento das actividades, como também lhes garantem uma maior segurança, tanto para o condutor como para o próprio veículo. As potencialidades associadas a estas ferramentas de gestão têm produzido grandes alterações nas áreas dos transportes, logística, actividades comerciais, assistência técnica, distribuição, construção civil, administração pública, entre outras. O leque de oferta destes sistemas de gestão de frotas é vasto, sendo possível encontrar desde soluções simples e intuitivas até soluções mais complexas. Inosat, Masternault, Frotcom, TomTom, Guardasat, Trackind Diary, Comut, C-Track, Tellus, Cartrack, Tecmic, FrotaLink são exemplo de empresas que actuam nesta área de actividade.
