Full textTracking manoeuvring military airborne targets with radar is problematic due to the low scan rates and the high levels of measurement noise. Surveillance systems using multiple radars have the benefit of an increased rate of observation and noise reduction but also have the problem of correlating observations from multiple sensors. Mehtods are discussed to correlate single observations from multiple radar sensors as well as assigning observations to existing tracks. Filtering methods to reduce measurement noise of the target tracks and methods to extrapolate the predicted position of targets are also explored.

Full textWe examine the approximate variational method to significantly reduce the time required for training the model instead of using the exact method. A system of fixed point equations is derived to iteratively update the free variational parameters. We also present the factored model in the case where all variables are continuous with the use of the conditional Gaussian distribution to model state transitions. The variational method is still employed in this case to speed up the model’s training process. The developed model is implemented and applied in recognizing daily activity in our smart home and the Nokia lab from multiple sensors. The experimental results show that the model is appropriate for fusing multiple sensors in activity recognition with a reasonable recognition performance.

Full textL'introduzione di sensori di profondità nel mercato di massa ha contribuito a rendere la visione artificiale applicabile in molte applicazioni reali, come l'interazione dell'uomo in ambienti virtuali, la guida autonoma, la robotica e la ricostruzione 3D. Tutti questi problemi sono stati originariamente affrontati con l'utilizzo di normali telecamere ma l'ambiguità intrinseca delle immagini bidimensionali ha portato allo sviluppo di tecnologie per sensori di profondità. La visione stereoscopica è stata la prima tecnologia a permettere di stimare la geometria tridimensionale della scena. Sensori a luce strutturata sono stati sviluppati per sfruttare gli stessi principi della visione stereoscopica ma risolvere alcuni problemi dei dispositivi passivi. Infine i sensori a tempo di volo cercano di risolvere lo stesso problema di stima della distanza utilizzando una differente tecnologia. Questa tesi si focalizza nell'acquisizione di dati di profondità da diversi sensori e presenta tecniche per combinare efficacemente le informazioni dei diversi sistemi di acquisizione. Per prima cosa le tre principali tecnologie sviluppate per fornire una stima di profondità sono esaminate in dettaglio, presentando i principi di funzionamento e i problemi dei diversi sistemi. Successivamente è stato studiato l'utilizzo congiunto di sensori, fornendo delle soluzioni pratiche al problema della ricostruzione 3D e del riconoscimento dei gesti. I dati di un sistema stereoscopico e di un sensore a tempo di volo sono stati combinati per fornire una mappa di profondità più precisa. Per ognuno dei due sensori sono state sviluppate delle mappe di confidenza utilizzate per controllare la fusione delle mappe di profondità. La mancanza di collezioni con dati di diversi sensori è stato affrontato proponendo un sistema per la collezione di dati da diversi sensori e la generazione di mappe di profondità molto precise, oltre ad un sistema per la generazioni di dati sintetici per sistemi stereoscopici e sensori a tempo di volo. Per il problema del riconoscimento dei gesti è stato sviluppato un sistema per l'utilizzo congiunto di un sensore di profondità e un sensore Leap Motion, per migliorare le prestazioni dell'attività riconoscimento. Un insieme di descrittori ricavato dai due sistemi è stato utilizzato per la classificazione dei gesti con un sistema basato su Support Vector Machines e Random Forests.

Full textAvhandlingen syftar till att upptäcka hur ett självstyrande system beroende av en rörelsekamera mäter sig jämfört med ett system som kombinerar en rörelsekamera med en ult- raljudssensor. Det primära syftet är att bevisa att ett smart fordon med sensorer kan följa ett radiostyrt fordon, kontrol- lera grundläggande funktionaliteter som styrning och gas, samt undvika kollision med fordonet framför. Avhandling- en undersöker genom småskaliga tester om ett fordon i en motorvägssituation kan följa ett annat fordon på ett säkert och kontrollerat sätt. Vi antar det arbete som presente- ras i denna avhandling också kan vara bevis för konceptet platooning. Funktionaliteten av det föreslagna systemet är giltigt enligt reglerna från Trafikverket. Dessa förhållanden replikerades i en testmiljö av liten ska- la och resulterade i att en kombination med en extra av- ståndsmätare gjorde att systemet kunde följa närmare och fortfarande undvika att krocka in i bilen framför.

Mineral aerosols emitted from arid and semi-arid regions effect global radiation, contribute to regional nutrient dynamics and impact local soil and water quality. Satellite imagery has been central to the identification and determining the distribution of source areas and the trajectories of dust around the globe. This study focuses on the dryland regions of Botswana, Namibia and South Africa. It uses the capabilities of the ultraviolet channels provided by the older Total Ozone Mapping Spectrometer (TOMS), the Ozone Monitoring Instrument (OMI) (a TOMS follow up), the visible bands of Moderate Resolution Imaging Spectroradiometer (MODIS), and the Spinning Enhanced Visible and Infrared Imager (SEVIRI) onboard Meteosat Second Generation (MSG). This study compares various dust detection products but also focuses on the application of thermal infrared bands from MSG through the usage of the new "Pink Dust" visua lisation technique using channels 7 (8.7 ~m), 9 (lO.8 ~m), and 10 (12.0 ~m). This multisensor approach resulted in a regional maps highlighting the distribution of source points and establishing some of the prevalent transport pathways and likely deposition zones. Southern African dust sources include a few large and many small pans, subtle inland depressions and ephemeral river systems, which are subject to a range of climatic conditions as part of the Kalahari and Namib region. This work in particular examines if source points are productive due to favourable climatic conditions. The debate around transport limit verses supply limit can only be solved at the local scale which requires observation at higher spatial and temporal resolution as provided by the latest dust detection products. MSG and MODIS in particular have shown distinct source point clusters in Etosha and the Makgadikgadi Pans which based on the courser resolution of older TOMS, have so far been treated as homogeneous sources. Data analyses reveal 327 individual dust plumes over the 2005-2008 study period, some of which are more than 300 km in length. These are integrated into existing climate and weather records provided by National Centers for Environmental Prediction (NCEP) data. The results identified a set dust drivers such as the Continental High Pressure, Bergwinds, Tropical Temperate and West Coast Troughs, and Westerly and Easterly Wave lows. This enhances our ability to predict such events, in particular, if transport acts as the limiting driver. Some of these find ings also have the potential to enhance our knowledge of the aerosol generation process elsewhere. The quality of findings are still limited by problems associated with dust plume substrates and clearly require significant surface validation relating to hydrological and climatic controls at the micro-scale. It is furthermore evident that no current instrument fully meets the requirements of the mineral aerosol research community.

Full textEste trabalho apresenta um sistema de interrogação de sensores a rede de Bragg em fibras ópticas, baseado em reflectometria no domínio do tempo e filtros fixos a rede de Bragg. Utilizando uma fonte de luz pulsada, a posição espectral do sensor é relacionada à razão da intensidade dos pulsos, tornando a detecção independente de variações de intensidade. São abordados aspectos teóricos e experimentais referentes aos princípios de funcionamento desta técnica. Uma vez que a filtragem é feita com redes de Bragg, apenas um circuito de fotodetecção é utilizado e um número reduzido de acopladores/circuladores ópticos é necessário, o sistema possibilita reduzir consideravelmente o custo para a interrogação de um conjunto de sensores. A utilização de apenas um circuito de fotodetecção apresenta a vantagem de manter as mesmas características para todos os pulsos, minimizando influências externas neste circuito como, por exemplo, variações da temperatura ambiente. Foi montada uma bancada de testes para a interrogação de seis sensores. Comparações entre os resultados experimentais e simulados mostram boa concordância. Extrapolações indicam que seria possível interrogar sensores com uma variação espectral de 2 nanômetros, com incertezas menores que 10 picometros, o que é adequado para sensores de temperatura. Análises de interferência entre dois canais adjacentes mostram pouca influência entre eles e são apresentadas opções para diminuir essa interferência.
This work presents a system for the interrogation of fiber- optic Bragg grating sensors based on time domain reflectometry and Bragg grating fixed filters. Using a pulsed light source, the spectral position of the sensor is related to the ratio of two pulses intensities, making detection independent of intensity variations. Theoretical and experimental aspects regarding the working principles of this technique are discussed. Since filtering is accomplished with Bragg grating so that only one photodetection circuit is used and a reduced number of optic couplers/circulators are needed, the system provides a considerable reduction in the cost of interrogation for a set of sensors. Using only one photodetection circuit also has the advantage of maintaining the same characteristics for all pulses, thus minimizing external influences in this circuit, such as variations in the environment temperature. A test stand was assembled for the interrogation of six sensors. Comparisons between experimental and simulated results show a good agreement. Extrapolations indicate that it would be possible to interrogate sensors with a spectral variation of 2 nanometers, with uncertainties lower than 10 pm, which is adequate for temperature sensors. Cross talk analyses between two adjacent channels show small influence between them, and approaches to reduce this interference are presented.

Full textFilamentous growth is a cell differentiation program utilized by Saccharomyces cerevisiae to respond to nutrient limitation in the environment. This process is principally controlled by a mitogen-activated protein kinase (MAPK) pathway but is also impacted by a number of other pathways including Ras2p-cAMP-PKA, Target of Rapamycin, Rim101, and mitochondrial retrograde. Using a high-throughput genetic screening approach in conjunction with directed gene-deletion analysis, I have identified 97 new regulators of the filamentous growth MAPK pathway. These new regulators created new connections to the filamentous growth MAPK pathway as well as extended previously known connections. I have linked several of the pathways governing filamentous growth together as part of an integrated signaling network by showing that these pathways regulate each other’s transcriptional targets. This network indicates an intricate level of communication and coordination among these pathways that has not been previously appreciated. I show that proper coordination of the filamentous growth MAPK pathway is essential for proper morphogenesis and this is a potential reason for the many inputs used to control this response. The filamentous growth MAPK pathway is also regulated by three transmembrane proteins – Msb2p, Sho1p, and Opy2p. Here these three proteins are compared to determine that they have specific functions in regulating filamentous growth. The three proteins exhibit different localization patterns and rates of turnover from the plasma membrane. I show that the Rim101 pathway affects the filamentous growth MAPK pathway independently of the ESCRT pathway which shares components with the Rim101 pathway. Additionally, I have shown that overexpression of the arrestin protein Aly1p results in mislocalized Msb2p and diminished pathway activity.

Full textWireless local area networks (WLANs) enable the extension of the Internet to aircrafts in flight. To establish this wireless network segment, commercial-of-the-shelve (COTS) 802.11b wireless Ethernet bridges were used. Wireless Ethernet bridges were chosen over optical wireless technology and Internet protocol (IP) satellite modems mainly because of their lower costs, ease and flexibility of implementation. Additionally, 802.11b wireless networks allow a wide range of mobile data devices such as laptop computers and personal digital assistance high-speed wireless access to critical information and applications resided on the aircrafts networks. Since 802.11b WLAN media is shared and traffic generated by other users will degrade the overall performance of the network. With the continual wide spread use of 802.11b WLAN, an aircraft in flight will experience network congestions and poor performance across all the frequency channels. The congestion and poor performance issues can be minimized by tracking the airborne wireless LAN using highly directional antenna and RF filtering. The method of tracking multiple 802.11 wirelesses LAN and the RF subsystem will be described. The applications of 802.11b wireless networks to man and unmanned aircrafts flight research will be discussed.

Machine vision systems are used in a wide range of applications such as security, automated quality control and intelligent transportation systems. Several of these systems need to extract information from natural scenes in the section of the electromagnetic spectrum visible to humans. These scenes can easily have intra-frame illumination ratios in excess of 10⁶ : 1. Solid-state image sensors that can correctly process wide illumination dynamic range scenes are therefore required to ensure correct reliability and performance. This thesis describes a new algorithm to linearly increase the illumination dynamic range of integrating-type image sensors. A user-defined integration time is taken as a reference to create a potentially large set of integration intervals of different duration (the selected integration time being the longest) but with a common end. The light intensity received by each pixel in the sensing array is used to choose the optimal integration interval from the set, while a pixel saturation predictive decision is used to overlap the integration intervals within the given integration time such that only one frame using the optimal integration interval for each pixel is produced. The total integration time is never exceeded. Benefits from this approach are motion minimization, real-time operation, reduced memory requirements, programmable light intensity dynamic range increase and access to incremental light intensity information during the integration time.
(cont.) The algorithm is fully described with special attention to the resulting sensor transfer function, the signal-to-noise ratio, characterization of types and effects of errors in the predictive decision, calculation of the optimal integration intervals set given a certain set size, calculation of the optimal number of integration intervals, and impact of the new algorithm to image data compression. An efficient mapping of this algorithm to a CMOS process was done by designing a proof-of-concept integrated circuit in a 0.18[mu]m 1.8V 5-metal layer process. The major components of the chip are a 1/3" VGA (640 x 480) pixel array, a 4bit per pixel memory array, an integration controller array and an analog-to-digital converter/correlated double sampled (ADC/CDS) array. Supporting components include pixel and memory row decoders, memory and converter output digital multiplexers, pixel-to-ADC/CDS analog multiplexer and test structures. The pixels have a fill factor of nearly 50%, as most of the needed system additions and complexity were taken off-pixel. The prototype is fully functional and linearly expands the dynamic range by more than 60dB.

Full textDrylands are among the most sensitive areas to actual global change and their cover will increase in the next decades. Terrain has a key role in the distribution of water and nutrients in drylands and shaping their composition. These environments are composed by vegetation and bare soil, many times colonized by biocrusts, which are expected to suffer compositional changes. Remote sensing has been highlighted as an important tool for dryland monitoring. It is a very cost-effective approach to identify biodiversity hotspots, predict changes in their composition, and to evaluate the relationships these changes have with the terrain. Using the proper image analysis according to the study case, remote sensing has proved to be useful for monitoring well differentiated drylands, but not when dryland components are mixed. Thus, the main aim of this dissertation was to study how heterogeneous dryland composition and functioning is affected by the terrain using different multiple remote sensing sensors and platforms. Data from very high spatial resolution RGB, thermal infrared, multi- and hyperspectral imagery, retrieved in the laboratory and in the field using airborne, UAV and stationary platforms were used. The next specific objectives were set: - Evaluating whether SfM techniques can be used in drylands with complex surfaces to derive their terrain from UAV imagery; - Developing a reproducible technique to relate human actions to changes in the health of dryland scarce vegetation communities by using object-based image analysis; - Testing whether the spectral heterogeneity of lichens can be used to estimate their α-diversity using hyperspectral imagery; - Developing a methodology to evaluate the control that terrain has on dryland biocrusts’ distribution using information solely retrieved from UAV; - Testing if TIR imagery can estimate soil moisture in heterogeneous drylands. This PhD thesis comprises an evaluation of SfM techniques at different scales and their applicability at different levels. It also comprises a novel methodology to monitor vegetation in a ground-water dependent ecosystem, where their health is key for the ecosystem’s functioning. Moreover, the application of close-range hyperspectral imagery allowed to estimate the α-diversity of biocrust-forming lichens using their spectral diversity. This led to a better understanding of the spectral behaviour of biocrusts depending on their composition and allowed to develop a methodology to produce accurate maps of land cover in a dryland ecosystem of heterogeneous composition and to relate the effect of terrain atrributes on dryland composition.
