La compagnie Sigfox est reconnue comme un acteur prometteur pour des transmissions de longue-distance et faible consommation, dans le contexte de l'IoT. La modulation à bande ultra étroite (Ultra Narrow Band (UNB)), la technologie de communication choisie par Sigfox, permet de transmettre des informations dans des bandes de signal très étroites (typiquement 100 Hz). A cause de l'imprécision fréquentielle causée par les oscillateurs générateurs de fréquence, il n'est pas réaliste de transmettre des signaux UNB dans des canaux parfaitement orthogonaux. L'accès naturel au canal radio pour le système de UNB est de type ALOHA, avec un aspect aléatoire à la fois en en temps et en fréquence. Cet accès aléatoire peut introduire des collisions qui dégradent la performance du réseau. Le but de cette thèse est de caractériser la capacité des réseaux basés sur UNB, ainsi que d’améliorer la performance en considérant l'aspect aléatoire en temps et en fréquence. La première contribution de cette thèse, est une évaluation de la capacité en théorie et en simulation pour une seule station de base (BS), sous des conditions de canal idéaliste ou réaliste. En conditions idéalistes, nous avons exprimé la capacité pour le cas de l'ALOHA généralisé, et l'avons étendu aux cas de réplications. Pour les conditions réalistes, nous avons pris en compte l'interférence spectrale d'UNB et le path loss (sans et avec Rayleigh fading) afin de caractériser la performance des réseaux UNB, avec l'outil géométrie stochastique. La deuxième contribution est d'appliquer l’annulation successive d'interférence (SIC), qui nous permet d'atténuer les interférences, dans des réseaux de UNB. Nous avons fourni une analyse théorique de la performance des réseaux en considérant le SIC et l'interférence spectrale de UNB, pour le cas de mono-BS. La troisième contribution est l'amélioration de la performance des réseaux UNB, en exploitant la diversité de multi-BS. Nous avons fait une analyse théorique de performance en considérant multi-BS et selection combining (SC). En particulier, nous avons considéré que l’interférence vue par chaque BS est corrélée. Nous avons ainsi démontré mathématiquement que cette corrélation ne peut pas être supprimée dans des systèmes UNB. Ensuite, nous avons appliqué les technologies de la combinaison des signaux plus complexes comme MRC (max ratio combining) et EGC (equal gain combining), ainsi que le SIC à travers multi-BS. Nous avons évalué l'amélioration de performance que chaque technologie apporte, et les avons comparées. Nous avons souligné l'efficacité de ces technologies qui nous permettent d’obtenir des gains importants comparés au cas mono-BS (e.x. 125 fois plus de réduction d'erreur avec SIC globale). La dernière contribution est une validation expérimentale du modèle d'interférence spectrale de UNB, ainsi que la capacité des réseaux UNB, sur un testbed de radio FIT/Cortexlab.

▼ Abstract A Recent study about data communication through existing power lines has been the subject interest of research for many researchers for over the past decade. Many researchers and industries have tried to develop and produce some devices to cover the disadvantages of using power line as data communication. This is because the power line is designed for transmission of power instead of signal transmitting originally. The heterogeneous structure of the power line network with numerous branches and impedance mismatches causing reflections and attenuation during signal transmission, and thus communication signal cannot be sent out or received completely. Furthermore, when the data communication trespassing the transformer, the disturbance, attenuation and degrading of signal become more severe. Orthogonal Frequency Division Multiplexing (OFDM) as one of the latest modulation and demodulation technique is used to achieve better digital data transmission over a limited bandwidth. This thesis serves as an investigation of the characteristics of Power Line Communication through Transformer with the presentation of a comprehensive and detailed analysis of the standards, mathematical modeling for PLC through Transformer, the latest modulation and demodulation technique used, and the behavior of PLC through Transformer based on the simulations and test results. The main aim of this research is to design a comprehensive idea about power line communication through transformer in order to propose and examine a novel approach in comparing the different modulation order, different modulation type, and also application of different noise types and applying them to the two modeled channels, Additive White Gaussian Noise (AWGN) and Powerline modeled channel. This is an attempt to understand and recognize the most suitable technique for the transmission of message or image within a communication system. In doing so, MATLAB and embedded Digital Signal Processing (DSP) and Communication systems are used to simulate the operation of virtual transmitter and receiver.

▼ Apesar dos avanços na deteção e terapêutica do cancro oral, a taxa de sobrevivência a 5 anos é extremamente baixa. A avaliação da cavidade oral é bastante acessível no que diz respeito ao exame clínico, no entanto o diagnóstico precoce continua a ser altamente limitado e pouco comum. Consequentemente, o desenvolvimento de métodos não invasivos para a avaliação de lesões pré-neoplásicas e neoplásicas têm vindo a fazer progressos no que diz respeito à qualidade de vida e taxa de sobrevivência dos pacientes. Objetivos: O objetivo deste estudo envolve a realização de uma revisão bibliográfica acerca da utilização do Narrow Band Imaging como um auxiliar de diagnóstico não invasivo na deteção precoce do cancro oral, enunciando as vantagens e limitações desta nova tecnologia e de que forma se veio a difundir. Por fim, pretendo indicar as previsões futuras para o NBI e verificar a acessibilidade do produto no mercado, tendo como base a questão “Será o Narrow Band Imaging verdadeiramente eficaz na deteção precoce do cancro oral?”. Material e Métodos: A pesquisa bibliográfica foi realizada através do acesso à Internet, nas bases de dados PubMed, SciELO e ScienceDirect. Os artigos analisados foram publicados entre 2004 e 2016. Fundamentação Teórica: O Narrow Band Imaging é uma técnica endoscópica que fornece em tempo real uma imagem ótica. Esta tecnologia envolve um conceito em que o sistema usa filtros que dissociam as bandas de espectro de luz salientando desta forma, a organização microvascular da mucosa e evidencia os laços capilares, que são estruturas específicas da mesma. Assim, o NBI pode ser bastante útil na deteção do cancro oral, especialmente quando nos encontramos perante um carcinoma espinocelular. Conclusão: O Narrow Band Imaging combinado com as técnicas endoscópicas clássicas melhora significativamente a deteção do cancro oral com uma sensibilidade muito aumentada. A deteção precoce aumenta o potencial para um tratamento pouco invasivo, reduzindo substancialmente o dano nos tecidos afetados, o que promove uma melhor qualidade de vida dos pacientes Advisors/Committee Members: AMARAL, JOSÉ MANUEL BARBAS DO.

Cette thèse a pour but de modéliser les réseaux de capteurs sans fil à faible débit (WSN) basés sur la technique ultra bande étroite. Ce réseau a déjà été déployée par la société SIGFOX et a déjà démontré sa très grande efficacité pour les applications pour l’Internet des objets (IoTs) grâce à sa capacité de communication point à point efficace en terme de puissance consommée, et de sa connectivité de longue portée. Cette étude donne quelques aperçus sur le passage à l’échelle de la technique de l’UNB pour un réseau multipoint à point pour une liaison montante. L’accès au canal spécifique qui est basé sur l’accès multiple par répartition aléatoire de fréquence et de temps (R-FTDMA) est introduit et analysé. En outre, l’impact de l’interférence due à l’absence de stratégie d’ordonnancement à la couche MAC est étudié et modélisé. Notre modèle simplifié nous permet non seulement de décrire la puissance d’interférence agrégée, mais aussi d’évaluer les performances du système d’un tel réseau en matière de taux d’erreur et de probabilité de coupure. De même, la géométrie stochastique est utilisée pour modéliser la distribution spatiale des noeuds afin d’étendre le modèle simplifié dans le canal réaliste où les dégradations de canal sont prises en compte. De plus, le mécanisme de retransmission est considéré pour ce réseau. Cette étude permet de d’identifier le nombre optimal de retransmissions. Le réseau peut être configuré avec un paramètre global unique. Et enfin, cette thèse met en évidence le fait que le réseau de l’UNB Random-FTDMA est très pertinent dans un réseau réaliste, en particulier pour les applications à faible débit, car il allége le coût élevé du réseau, le coût de la synchronisation globale, mais sans perte de performance.

This thesis aims at modeling the low-throughput wireless sensor networks (WSNs) based on ultra-narrow-band technology. Such wireless network is already been deployed by Sigfox company and has proved to be ultra-efficient for the Internet of things (IoTs) applications thanks to its ability of point-to-point communication in terms of power efficiency and long range connectivity. In particular, this thesis gives some insights on the scalability of UNB technology for a multi-point-to-point network in an uplink scenario. The multiple access schemes based on random time and frequency selection are introduced and analyzed. Furthermore, the interference impact due to the lack of scheduling strategy at the MAC layer is studied and modeled. Our simplified model using rectangular function allows us not only to describe the aggregate interference power but also evaluate the system performance of such network in terms of the bit-error-rate and outage probability. Besides, the geometry stochastic is used for spatial node distribution in order to extend the simplified model in the realistic channel communication where the channel impairments are taken into account. Besides, the retransmission mechanism is considered for such network. This study argues an optimal number of retransmission. The network…

▼ A significant challenge in the surgical resection of tumors is accurate identification of tumor margins. Current methods for margin detection are time-intensive and often result in incomplete tumor excision and recurrence of disease. The objective of this project was to develop a near-infrared narrowband imaging (NIR NBI) system to image tumor and its margins in real-time during surgery utilizing the contrast provided by gold nanoparticles (GNPs). NIR NBI images narrow wavelength bands to enhance contrast from plasmonic particles in a widefield, portable and non-contact device that is clinically compatible for real-time tumor margin demarcation. GNPs have recently gained significant traction as nanovectors for combined imaging and photothermal therapy of tumors. Delivered systemically, GNPs preferentially accumulate at the tumor site via the enhanced permeability and retention effect, and when irradiated with NIR light, produce sufficient heat to treat tumor tissue. The NIR NBI system consists of 1) two LED's: green (530 nm) and NIR (780 nm) LED for illuminating the blood vessels and GNP, respectively, 2) a filter wheel for wavelength selection, and 3) a CCD to collect reflected light from the sample. The NIR NBI system acquires and processes images at a rate of at least 6 frames per second. We have developed custom control software with a graphical user interface that handles both image acquisition and processing/display in real-time. We used mice with a subcutaneous tumor xenograft model that received intravenous administration and topical administration of gold nanoshells and gold nanorods. We determined the GNP's distribution and accumulation pattern within tumors using NIR NBI. Ex vivo NIR NBI of tumor xenografts accumulated with GNPs delivered systemically, demonstrated a highly heterogeneous distribution of GNP within the tumor with higher accumulation at the cortex. GNPs were observed in unique patterns surrounding the perivascular region. The GNPs clearly defined the tumor while surrounding normal tissue did not indicate the presence of particles. In addition, we present results from NBI of tumors that received topical delivery of conjugated GNPs. We determined that tumor labeling using topical delivery approach resulted in a more homogenous distribution of GNPs compared to the systemic delivery approach. Finally, we present results from the on-going in vivo tumor margin imaging studies using NIR NBI. Our results demonstrate the feasibility of NIR NBI in demarcating tumor margins during surgical resection and potentially guiding photo-thermal ablation of tumors.

Radar has been used for remote sensing and surveillance for decades. Nowadays radar remote sensing and radar surveillance is used for many different things in the modern society. Radar can sense objects or environments from very long distance. Electromagnetic radar waves can work where and when light cannot. This unique ability of radar made remote sensing techniques available in research and in industrial applications. Radar can operate in any climate and any time of the day. Using ultra-wideband (UWB) pulses for radar in combination with synthesizing apertures, which is so called synthetic aperture radar (SAR), enables radar to produce high resolution images in both range and azimuth directions. The work presented in this thesis uses SAR for oil well monitoring. SAR is seen as a good candidate to follow oil well changes in time by means of maintenance. Other methods to perform this task have been introduced and implemented but they are not able to produce high resolution images from the oil well. Using SAR for oil well monitoring provides high resolution images of oil well walls in order to detect the asphaltene or bitumen. The resolutions of images can be enhanced by using UWB signal and SAR processing. Asphaltene and bitumen are the heavy components of crude oil and capable of blocking the porous media in oil well. The porous media is called damaged material when its holes are blocked by asphaltene or bitumen as it cannot pass the oil any more. A decrease in oil production is the consequence of this phenomenon. If these materials can be detected at very beginning stages of formation, addition of solvent at the location of the detected materials can be very helpful for oil well maintenance. This thesis is divided in to two parts. The first part focuses on SAR processing whereas the second one aims at antenna design and fabrication to work in a ground penetrating synthetic aperture radar (GPSAR) system. In the first part, an oil well model based on the measured electrical properties of common oil well materials is introduced. SAR processing is then applied to the oil well model to reconstruct SAR image of the oil well. The resulting SAR image is shown to provide high resolutions so that different materials can be distinguished. In the second part, a modified TEM horn antenna for SAR is designed, simulated and fabricated. The antenna is customized to work in oil media. A new profile model for the TEM horn antenna is proposed that modifies the antenna radiation pattern in the design. The antenna measurements are shown to be in agreement with the simulated results.

Oil well monitoring is very important for the oil and gas industry. Therefore in this thesis, a new ultra-wideband (UWB) ground penetrating radar (GPR) system for detection of near wellbore formation damage is introduced. The proposed GPR uses ground penetrating synthetic aperture radar (GPSAR) and a new developed transverse electromagnetic (TEM) horn antenna to increase GPR image resolution. The work has therefore been divided in two parts of…

▼ Bioimaging techniques are not only important in clinical diagnosis but in research. As many bioimaging techniques are developed, fluorescence technique is one of the important bioimaging methods that is really useful in clinical diagnosis and research due to its good spatial resolution and time resolution. Semiconducting polymer dots (pdots) has the potential for bioimaging fluorescence probe because of its good quantum yield, high phtostability, suitable size for bioconjugation, low biotoxicity and tunable emission wavelengths. Pdots has drawn many scientistâs attentions due to its advantages and really suitable for in vitro/vivo bioimaging research. ããReacently different wavelength pdots have been developed including near infrared emmition pdots. This is significant for bioimaging because near infrared has more penetration distance which can travel longer in the tissue and it can eliminate the autofluorescence of biomolecule in human body to reduce the noise. The most important of near infrared fluorescence probe, it is revatively lower energy than other wavelength fluorescence probe. However, the challenging part of developing NIR pdots is most NIR dyes with many Ï conjugated structures and benzenes tend to have Ï-Ï stacking in aggregation form that lead to ACQ effect (aggregation caused quenching) which cuase NIR dyesâ low quantum yield. Moreover, our lab has develop some NIR emission pdots, unfortunately the emission band was relatively broad (80-150 nm), and still challenging for multicolor bioimaging due to the emission section cross-over. ããTherefore, my first section of this paper is that molecular engineering and design of semiconducting polymers to develop polymer dots as fluorescent probe with narrow-band, near- infrared emission for in vivo biological imaging. By using synthetic method, we develop polymer with donor-bridge-acceptor structure that the donor prvide basic steric hindrance and absorption of light for pdot; there are four bridges we used that have increasing bulky structure and they provide bulky side chain for pdots to prevent from ACQ effect; finally, we select two near-infrared dyes with narrow-band emission: pthalocyanine (Pc) and boron-dipyrromethene (BODIPY) as our acceptor. In this section, we optimized all combination of the donorãbridgesãacceptors and come up with the best enrgy transfer ration of each polymer. Then we chose the best performance of the pdots for further experiment such as cell labelingãzebra fish bioimaging and mice tumor tracking. ããSecond section of this paper is design of PFO pdots with boronic acid based anthracene dyes for glucose sensing. Glucose concentration in human blood is really important in clinical diagnosis and daily follow-up for patients with cardiovascular disease. Therefore, the second section of this paper we combined PFO pdots that has 550 nm fluorescence and boronic acid based anthracene dye (AAS) that is a dye will turn on when chelate with glucoe and emits green fluorescence. The mechanism in this project is using the PFO pdots with good… Advisors/Committee Members: Yang-Hsiang Chan (committee member), Ho-Hsiu Chou (chair), Jie-Ren Li (chair).

▼ O carcinoma foi a principal causa de morte para cerca de 8,2 milhões de habitantes no ano de 2012 a nível mundial. Deste valor, estima-se que o carcinoma colo retal foi responsável por 694.000 mortes nesse mesmo ano. O tratamento eficaz deste carcinoma carece de uma deteção precoce de determinadas patologias associadas, nomeadamente, à presença de hemorragia ou pólipo na mucosa intestinal. Essa deteção precoce passa pela realização frequente de determinados exames clínicos invasivos, como a endoscopia e a colonoscopia, que poderão ser demasiado invasivos para o Homem para serem realizados regularmente. Assim surgiu a capsula endoscópica (CE) como método de diagnóstico pouco invasivo, confortável, seguro e com a funcionalidade de permitir a visualização de todo o trato gastrointestinal (TGI), uma vez que, com os métodos tradicionais de diagnóstico (endoscopia e colonoscopia) isso não acontece. Técnicas computacionais de processamento e análise de imagem automáticas, tais como filtros de suavização, remoção de ruído, deteção de contorno ou segmentação de zonas de interesse, podem ser utilizadas para facilitar a deteção destas patologias e homogeneizar a resposta entre diferentes clínicos, uma vez que, por cada exame de endoscopia por capsula são recolhidas cerca de 57 600 imagens. As imagens recolhidas a partir da CE passam por uma série de passos de processamento de imagem a m de clarificar a existência ou ausência de patologias no interior do TGI. Essa classificação pretende simplificar e auxiliar o clínico no diagnóstico precoce relativamente às patologias em causa, assim como reduzir o seu cansaço, aumentar a sua performance e aumentar a sua eficiência na análise de dados. Neste contexto e em parceria com a empresa INOVA+, esta tese está integrada no projeto PhotonicPill cofinanciado pelo QREN (Quadro de Referência Estratégico Nacional). Este projeto visa desenvolver um conjunto de módulos baseados em fotónica para incorporar numa CE, a m de possibilitar um diagnóstico mais preciso e atempado de diversas patologias, nomeadamente a presença de pólipos e hemorragias, assim como a possibilidade de terapêutica em locais do trato gastrointestinal de difícil acesso, como é o caso do intestino delgado. Um dos módulos baseados em fotónica assenta na tecnologia narrow band imaging (NBI). A contribuição desta tese no projeto prendeu-se no desenvolvimento de 3 métodos de deteção automática. O primeiro direcionado para a deteção de hemorragia, baseou-se na identificação dos valores mínimos e máximos dos canais de R,G,B para criar um valor de threshold duplo. De seguida, complementa-se o método através de operações morfológicas e operações locais. O segundo método de deteção automática é direcionado para a deteção de pólipo e baseou-se na aplicação da transformada de watershed juntamente com o cálculo de medidas associadas à forma típica de um pólipo. Por último, desenvolveu-se um método de deteção de vascularização na mucosa intestinal recorrendo essencialmente à deteção de valores máximos para cada canal do modelo RGB,… Advisors/Committee Members: Faria, Luiz Felipe Rocha de, Santos, Carla.

Tradicionalmente, o processo de análise para obtenção da vida à fadiga em sistemas estruturais ou componentes mecânicos sujeitos a carregamentos dinâmicos é realizado no domínio do tempo, procedimento que, mesmo sendo amplamente conhecido, demanda maior tempo e esforço computacional. Nas últimas décadas, tem se aperfeiçoado métodos de solução no domínio da frequência que vêm apresentando maior eficiência e mostrando-se competitivos, além de um campo com promissor potencial de desenvolvimento. Assim, neste trabalho será desenvolvida uma abordagem visando reduzir os recursos computacionais consumidos numa análise de vida à fadiga, utilizando para isso métodos no domínio da frequência, onde excitação e resposta são representadas por PSD, e também uma abordagem de análise Global-Local. Para isso, será realizada uma sequência de etapas que de forma resumida são: geração do modelo Global, análise modal, geração do modelo Local e matriz de compatibilidade, cálculo da PSD a partir do carregamento, transformação do sistema para o domínio da frequência, montagem da Função de Resposta em Frequência, e por fim, utilizando dados da curva S-N do material será realizada a aplicação do modelo de Dirlik para prever a vida em fadiga. Todas estas etapas foram implementadas em programa numérico, e seus resultados testados com exemplos da literatura, gerando assim, um conjunto de ferramentas para pesquisa da fadiga no domínio da frequência. O estudo desenvolvido utiliza como hipóteses que a resposta do sistema estrutural seja linear, o carregamento seja randômico, estocástico e ergódico, a distribuição de picos siga uma distribuição gaussiana, e o método probabilístico para previsão da vida a fadiga se baseie nos parâmetros espectrais.

Traditionally the analysis process to obtain the fatigue life of structural systems or mechanical components subjected to dynamic loading is performed in the time domain, a procedure which, although widely known, requires more time and computational effort. In the last decades it has been optimized solution methods in the frequency domain that has shown greater efficiency and proving to be competitive, besides a field with promising potential development. Thus, this work will be developed an approach aimed at reducing the computational resources consumed in an analysis of fatigue life, using for this frequency domain method, where excitement and response are represented by PSD, and also a global-local analysis approach. Thereunto, there will be a sequence of steps that briefly are: Global model generation, modal analysis, generation of local model and compatibility matrix, calculation of the PDS from the load, system transformation to the frequency domain, assembly frequency response function and finally, using data from the SN curve of the material will be realized the application of Dirlik model to predict the fatigue life. All these steps were implemented in numerical software and their results were tested with literature examples, generating a set of search tools to fatigue in the frequency domain.…

ENGLISH ABSTRACT: This dissertation proposes two narrow-band tunable X-band filters from different classes, one planar and one waveguide. The first is a suspended substrate varactor-tuned doubly end-loaded staircase filter that incorporates a geometrically decoupled biasing structure. The second design consists of a varactor-tuned evanescent mode waveguide filter that incorporates tuning screws and a symmetrical varactor mounting structure inside the guide. The filters are designed for miniaturization with competitive filter performance in terms of centre frequency tunability, insertion loss and bandwidth performance. A planar staircase filter with electrically decoupled biasing and centre frequency tunability is realised using a suspended substrate and surface mount varactor diodes. Each half-wave resonator is terminated at both ends with identical varactor diodes, controlled by a single biasing line running through the roof of the enclosure. For symmetrically loaded half-wave resonators such as used in the staircase filter, each resonant line is DC decoupled from the next and a zero-voltage point exists in the centre of each line. This point is stationary under changes in centre frequency, which is a significant advantage for tunable filters. The biasing structure is also non-resonant, which allows for good out-ofband performance. The proposed planar structure is illustrated by a fifth order staircase X-band filter. Using varactors at each open end of the resonators together with spatially decoupled bias feeds, a measured centre frequency tunability of 400 MHz is achieved around a nominal frequency of 11.9 GHz. The tunable evanescent mode waveguide filter is realised with in-waveguide mounted varactors and tuning screws. The mechanical tuning screws enable rough-tuning, while the varactors provide fine-tuning capabilities. The varactors are connected back-to-back on central metal plates which are grounded to the enclosure. The other end of each varactor is connected to a biasing wire which exits the enclosure through a small hole in the side of the waveguide. A centre frequency tunability of 1:3 GHz around a nominal frequency of 10:45 GHz is achieved by the manufactured filter prototype. Both filters are evaluated through theory and simulation in terms of the thermal resistance of the mounting structure and input power limitations due to the non-linearity and power dissipation of the varactor diodes. Across the full tuning range of the planar filter, the maximum input power limit is 8 dBm. For the waveguide filter, the simulation yielded a maximum input power limit for full range tunability of 2 dBm due to the nonlinearity of the hyperabrupt varactor diode, the applied voltage, and the power dissipation in the varactors. The proposed biasing structure is a novel method for biasing planar filters, and to the knowledge of the author, this is the first application of the specified in-waveguide mounted diode structure in tunable evanescent mode waveguide filters.

▼ Lung cancer is the leading cause of cancer fatalities in the world. The 5-year survival rate of patients is only 18%, primarily because lung cancer is detected at a late stage for 75% patients, in spite of all the improvements in bronchoscopy and radiological imaging. Early detection of lung cancer can help in decreasing the mortality rate from this disease. In this thesis, we have developed methods to enhance and segment blood vessels automatically from narrow band imaging (NBI) bronchoscopic videos. The objective is to facilitate early detection of lesion growth in the airway tract in future by detecting vessels that can potentially supply blood to these lesions. The work has been motivated based on the observed limitations of subjective visual inspection of enormous volumes of data stored in NBI videos. Identification of the nonvasculature regions will be also very useful to conduct biopsy and other tests on the airway. We divide our methods into the following steps. At first, we extracted image frames from the NBI videos which are RGB images which have then been converted to HSV image frames to obtain the value channel. Then anisotropic diffusion is applied on the value channel to make the images less noisy. After that Hessian-based vessel enhancement equations have been implemented, followed by segmentation with masks, obtained from logical combinations of image clusters obtained by applying k-means clustering algorithm on the RGB image. The evaluation has been done by calculating sensitivity, specificity and accuracy performance metrics. Ground-truthing was done on some image frames manually as the initial dataset was not labeled. Our methods have achieved an aggregate statistics of 94% accuracy, 94.6% specificity and approximately 70% sensitivity while segmentation on some frames have led to very high sensitivity of 87.5% and specificity and accuracy above 96%. In this thesis, we have demonstrated that the segmented results from our vessel enhancement and segmentation techniques are quantitatively better than the existing vessel enhancement methods. This result shows the success of identifying almost all the vascular and non-vascular region which will be useful in future work on early cancer detection.

▼ Colorectal cancer (CRC) is among the commonest and deadliest types of cancer. It is the second highest in economic burden among all cancers and the thirteenth of all diseases in Australia. In Japan, it has been gaining importance and in 2018 CRC was identified as second in incidence among all cancers for both women and men, and the leading cause of death amongst all cancers in women and the third leading cause of death in men. Research that can improve the prevention and treatment of this cancer is of the utmost importance. In primary prevention, I studied the factors that contribute to the development of colorectal lesions (e.g. colorectal adenomas and sessile serrated adenomas/polyps). This was a prospective study carried out at the Lyell McEwin Hospital (South Australia) examining whether and by how much factors such as alcohol consumption and smoking are associated with colorectal lesions. A cohort of 291 procedures and 260 patients was recruited. In this cohort, we found that different factors are associated with different histologic subtypes of lesions. Furthermore, in terms of primary prevention of CRC, I sought to discover how to optimally conduct colonoscopy (e.g. in the morning or afternoon). This, added to research on the simplification of methods for assessing quality measures (e.g. adenoma detection rate – ADR – through adenoma detection quotient - ADQ), was aimed at optimising CRC screening programs. In the retrospective cohort of 2,657 procedures performed at the Lyell McEwin Hospital (South Australia), morning endoscopy lists were associated with better detection and ADQ was a reliable predictor of ADR. With respect to secondary prevention, I undertook several studies. The main aim of these studies was to assess advanced endoscopic imaging (e.g. narrow band imaging - NBI) nationally and internationally, comparing different endoscopic classification methods for colorectal lesions to evaluate how well each performed. Two of our studies showed that the modified Sano's (MS) classification was the most accurate tool for predicting the histology of colorectal lesions during colonoscopy. The first of these two studies involved a single centre randomised trial on 348 patients comparing the MS with the NBI international colorectal endoscopic (NICE) classification, but did not include the differentiation of sessile serrated adenomas/polyps (SSA/Ps) in the comparison. The second, a prospective study between Australia (exploratory phase with 483 colorectal lesions included) and Japan (validation phase with 30 colorectal lesions evaluated by four endoscopists), involved the comparison of the MS, NICE and Japan NBI expert team (JNET) classifications. The last two classifications were combined with the workgroup serrated polyps and polyposis (WASP) add-on to allow the comparison including SSA/Ps' differentiation. The results from both studies were then used as a template for the development of a computer-aided diagnosis (CAD) system that could enable expert-level accuracy for any endoscopist. A CAD system was… Advisors/Committee Members: Burt, Alastair D. (advisor), Singh, Rajvinder (advisor), Carneiro, Gustavo (advisor), Adelaide Medical School (school).

▼ Tarkistettava väitöskirjatyö tutkii mahdollisuutta parantaa D-vitamiinitasoa ihotautien hoidossa käytettävällä valohoidolla, kapeakaistaisella UVB-valotuksella (aallonpituus 311 ± 2 nm). Väitöskirjan ensimmäisessä osatyössä tutkittiin kapeakaistaisen UVB-valotuksen vaikutusta atooppista ihottumaa ja psoriaasia sairastavien ihottumapotilaiden D-vitamiinitasoihin. Toisessa osatyössä verrattiin kapeakaistaisen UVB-valotuksen ja suun kautta otettavan D-vitamiinilisän tehoa D-vitamiinitasapainoon terveillä henkilöillä talvella. Muissa osatöissä tutkittiin kapeakaistaisen UVB-valotuksen vaikutusta D-vitamiinitasoihin dialyysihoidossa käyvillä munuais-potilailla, joista osalla oli ja osalla ei ollut käytössä suun kautta otettava D-vitamiinilisä. Väitöskirjan osatöissä todettiin, että kapeakaistainen UVB-valotus on nopea ja tehokas tapa parantaa D-vitamiinitasapainoa talvella ihotauti- ja dialyysipotilailla sekä terveillä henkilöillä. Kapeakaistaista UVB-valotusta voidaan käyttää myös munuaispotilailla, joilla on matalat D-vitamiinitasot käytössä olevasta suun kautta otettavasta D-vitamiinilisästä huolimatta. Teho kestää parin kuukauden ajan. Tutkimuksissa todettiin, että D-vitamiinin muodostusta tapahtuu maksan ja munuaisten lisäksi ihossa kapeakaistaisen UVB-valotuksen vaikutuksesta.; Narrow-band ultraviolet B (NB-UVB) phototherapy is used to treat dermatological diseases such as psoriasis and atopic dermatitis. Some previous studies have suggested that it also increases serum 25-hydroxyvitamin D (25(OH)D) concentrations. On the other hand, most patients with chronic kidney disease (CKD) requiring dialysis are known to have insufficient vitamin D. We therefore conducted trials to assess how short NB-UVB courses could affect serum 25(OH)D concentrations in dermatological and haemodialysis patients in winter, when little UVB from the sun is available for vitamin D synthesis. In addition, we compared the effects of an NB-UVB course and oral vitamin D supplementation on serum 25(OH)D concentrations in healthy subjects. In the first trial 89% of the patients with psoriasis, 94% of those with atopic dermatitis and 53% of the healthy subjects were found to have baseline vitamin D insufficiency (serum 25(OH)D <50 nmol/L). A course of 15 whole body NB-UVB exposures significantly increased serum 25(OH)D (p <0.001), by 59.9 nmol/L in the psoriasis patients, 68.2 nmol/L in the atopic dermatitis patients and 90.7 nmol/L in the healthy subjects. PASI (psoriasis area and severity index) and SCORAD (severity scoring of atopic dermatitis) improved significantly (p <0.001), but no correlation with the increase in serum 25(OH)D was found. Expression of antimicrobial peptides (AMPs), cathelicidin and human β-defensin 2 (HBD2) was high in the psoriasis skin lesions. After 6 NB-UVB treatments cathelicidin had increased further, while HBD2 expression had decreased. NB-UVB caused a marked but non-significant decrease in the cytokines interleukin (IL)-1β and IL-17 in the psoriasis lesions. It was concluded that, in addition to a significant…

Ce mémoire présente une méthodologie de conception d’antennes Ultra Large Bande volumiques à ondes progressives, d’encombrement réduit, dédiées au rayonnement d’impulsions ultra-courtes dans une bande de fréquence allant de 300 MHz à 3 GHz. L’objectif est de concilier une large bande de fréquences rayonnées et de bonnes performances de rayonnements transitoires (niveau élevé, signaux brefs) tout en limitant l’encombrement des antennes. L’insertion d’un matériau diélectrique a été associée au design des antennes ULB afin de réduire leurs dimensions. Ceci a conduit à la synthèse et à la caractérisation de matériaux diélectriques innovants à base de géopolymères, dont la maîtrise de la valeur de la permittivité est possible. Un prototype d’antenne a été réalisé, des mesures des différentes caractéristiques de rayonnement ont été effectuées et comparées aux résultats de simulation pour s’assurer du bon fonctionnement de celle-ci. Cette antenne a également été associée à des applications radar pour la détection de cibles se situant dans différents milieux (air et sol). Les réponses impulsionnelles obtenues pour les différentes scènes radar testées ont été comparées aux résultats mesurées avec d’autres antennes connues.

This thesis presents the design of small form factor Ultra Wide Band antennas with progressive waves shape, which is dedicated to ultra-short pulses radiation in a frequency band ranging from 300MHz to 3GHz. The aim is to combine a wide band of radiated frequencies and good performance while limiting the size of antennas. The insertion of a dielectric material has been associated with the design of Ultra Wide Band antennas to reduce their dimensions. This has led to the synthesis and characterization of innovative dielectric materials based on geopolymers, whose mastering of the value of the permittivity is possible. An antenna prototype has been manufactured and measurements of the different radiation characteristics were made and compared to the simulation results to ensure its good functioning. This antenna has also been associated with radar applications for the detection of targets in different environments (air and soil). The impulse responses obtained for the different tested radar scenes have been compared with the results obtained with other known antennas.

▼ In this report, we give a deeper investigation of the loss-compensated recirculating delayed self-heterodyne interferometer (LC-RDSHI) for ultra-narrow linewidth measurement, including the theoretical analysis, experimental implementation, further modification on the system and more applications. Recently, less than 1kHz linewidth fiber lasers have been commercialized. But even the manufacturers face a challenge on accurately measuring the linewidth of such lasers. There is a need to develop more accurate methods to characterize ultra-narrow laser linewidth and frequency noises. Compared with other currently available linewidth measurement techniques, the loss-compensated recirculating delayed-heterodyne interferometer (LC-RDSHI) technique is the most promising one. It overcomes the bottle-neck of the high resolution requirement on the delayed self-heterodyne interferometer (DSHI) by using a short length of fiber delay line. This method does not need another narrower and more stable laser as the reference which is the necessary component in heterodyne detection. The laser spectral lineshape can be observed directly instead of complicated interpretation in frequency discriminator techniques. The theoretical analysis of a LC-RDSHI gives us a guidance on choosing the optimal parameters of the system and assists us to interpret the recorded spectral lineshape. Laser linewidth as narrow as 700Hz has been proved to be measurable by using the LC-RDSHI method. The non-linear curve fitting of Voigt lineshape to separate Lorentzian and Gaussian components was investigated. Voigt curve fitting results give us a clear view on laser frequency noises and laser linewidth nature. It is also shown that for a ultra-narrow linewidth laser, simply taking 20dB down from the maximum value of the beat spectrum and dividing by 2√{99} will over estimate the laser linewidth and coherent length. Besides laser linewidth measurement in the frequency domain, we also implemented time-domain frequency noise measurement by using a LC-RDSHI. The long fiber delay obtained by a fiber recirculating loop provides a higher resolution of frequency noise measurement. However, spectral width broadening due to fiber nonlinearity, environmental perturbations and laser intrinsic 1/f frequency noises are still potential problems in the LC-RDSHI method. A new method by adding a transmitter switch and a loop switch is proposed to minimize the Kerr effect caused by multiple recirculation.

▼ Ultra-wideband (UWB) communication has been the subject of extensive research in recent years due to its unique capabilities and potential applications, particularly in short-range multiple access wireless communications. However, many important aspects of UWB-based communication systems have not yet been thoroughly investigated. The propagation of UWB signals inside very small enclosed environments is one of the important issues with significant impacts on the future direction, scope, and generally the extent of the success of UWB technology. The objective of this thesis is to obtain a more thorough and comprehensive understanding of ultra-small UWB channels for communication applications and design issues for enhancing the data rate of UWB systems. This works supports the postulation of a high capacity UWB wireless interconnect scheme for communicating devices within conducting enclosures – a wireless “backplane”. This thesis proposes the use of an Ultra-Wide Bandwidth (UWB) ultra-small scale wireless interconnect scheme for use within electrically small enclosures. Such ultra-small environments (size ≤ 10 wavelengths) are topologically much more complex, being more cluttered, than typical indoor environments (size ≥ 10 wavelengths). The concept is presented through two different scenarios. Firstly, a PC Tower case is presented as a model environment and the work seeks to present the optimum channel performance, where EMI issues are discussed and problem avoidance proposed. Secondly, in order to extrapolate the different results from the study inside the PC, an investigation is carried out using an Aluminium tower case as a more generic model environment. The analysis is based on the behaviour of box modes within a conducting resonator enclosure and the effective communications bandwidth for UWB systems for different sizes and components within. From these general considerations the research presents theoretical and experimental results from which are derived the communications metrics measured within enclosures. Simulations of the different scenarios are performed using different techniques such as ray tracing and a full wave model, based on CST Microstripes. Empirical data is recorded using a vector network analyser (VNA)-based wideband channel sounding system where channel measurements are carried out in every scenario regarding different aspects such as frequency response and time domain analysis, evaluation of the channel capacity, power delay study and the nature of the environment.

▼ The reliance on location and location based services in everyday life is undergoing tremendous growth as society progresses towards an increasingly connected world. Location awareness plays an important role in many applications such as navigation, mapping, exploration, emergency response, surveillance, search and rescue, etc. and forms an integral component of almost all modern technologies some of which include connected vehicles, Intelligent Transport Systems, Unmanned Aerial Vehicles (UAVs), Internet of Things (IoT) and smart cities. UAVs are increasingly being used in the above mentioned applications as well as in other domains such as agriculture and insurance. The use of UAV in any applications is contingent to precise and continuous localisation of the UAV platform. Till today, GNSS has been the primary source for achieving a precise localisation solution. However, the performance of GNSS is subject to the availability of clear outdoor environments and degrades substantially in occluded environments such as urban canyons and forests. A new paradigm of positioning is emerging that utilises cooperation and information sharing among UAVs as well as existing infrastructure and other platforms (or nodes) for localisation and is termed as ‘Cooperative Localisation’. Information sharing among nodes can help overcome some of the challenges including precise and continuous positioning in challenging environments such as urban environments, forests etc. Further, cooperative localisation may help in improving the positioning accuracy and is required for the deployment of UAV swarms in various applications. Although the advantages of cooperative localisation have been apparent, the performance of a cooperative localisation system of a swarm of UAVs, impact of various components on its performance and its advantages and limitations have not been evaluated in real world conditions. This research develops the mathematical framework and a prototype of a cooperative localisation system for a swarm of UAVs using GNSS, inertial and Ultra Wide Band sensors and performs an extensive performance analysis using multiple real world experiments. Notable developments achieved in this research include design and development of a new cooperative localisation prototype for a UAV swarm network, a general framework for cooperative localisation in heterogeneous and homogeneous cooperative networks using centralised architecture, development and evaluation of a new distributed EKF based estimation algorithm that is less computationally expensive than existing algorithms. Following a critical analysis of the existing literature to identify the research gaps, the details of the developed prototype are presented. Further, a performance analysis of the on-board sensors is performed to establish the performance parameters that are needed for information fusion. This is followed by the development of a general mathematical framework for cooperative localisation in centralised and distributed architectures for both heterogeneous and…

▼ AIM: To explore mutations in serine/threonine kinase 11 (STK11) gene in Peutz-Jeghers syndrome (PJS) with gastrointestinal (GI) hamartomatous polyps. METHODS: Six Japanese PJS patients in 3 families were enrolled in this study. Each of the cases had hamartomatous polyposis in the gastrointestinal tract, including the small intestine, along with mucocutaneous hyperpigmentation. Narrow-band imaging (NBI)-magnification endoscopy was employed to detect microvascular and microsurface irregularities in the GI lesions. NBI magnification findings could be classified into three groups (type A, type B, or type C). Endoscopic polypectomy was performed using double-balloon enteroscopy or colonoscopy. Genomic DNA was extracted from a whole blood sample from each subject. All of the coding exons of STK11 gene, its boundary regions, and the promoter region containing the polymorphic regions were amplified by polymerase chain reaction, and direct sequencing was performed to assess the germline mutations. RESULTS: NBI-magnification endoscopic observation could detect the abnormalities in microvessels and microsurface structures of GI polyps. Overall, we found 5 cases of type A and one case without the examination for the gastric polyps, while there were 4 cases of type B and 2 case of type A for the colorectal polyps. Seventy-nine small-bowel and 115 colorectal polyps over 27 sessions for each were resected endoscopically without significant complications. The only delayed complication included the occurrence of bleeding in a case, and this was successfully managed with hemoclips. Resected polyps contained no malignant components. Based on mutation analysis, all 3 cases in Family I exhibited the +658C>T nonsense mutation in exon 5, which resulted in the production of a truncated protein (Q220X). In Family II, a case had -252C>A and -193C>A in the promoter region. In Family III, a case was found to have the +1062C>G (F342L) mutation in exon 8. CONCLUSION: We found two novel mutations of STK11 in association with PJS. Endoscopic polypectomy of GI polyps in PJS patients appears to be useful to prevent emergency laparotomies and reduce the cancer risk.

▼ The occurrence of narrowband interference near frequencies carrying information is a common problem in modern control and signal processing applications. A very narrow notch filter is required in order to remove the unwanted signal while not compromising the integrity of the carrier signal. In many practical situations, the interference may wander within a frequency band, in which case a wider notch filter would be needed to guarantee its removal, which may also allow for the degradation of information being carried in nearby frequencies. If the interference frequency could be autonomously tracked, a narrow bandwidth notch filter could be successfully implemented for the particular frequency. Adaptive signal processing is a powerful technique that can be used in the tracking and elimination of such a signal. An application where an adaptive notch filter becomes necessary is in biomedical instrumentation, such as the electrocardiogram recorder. The recordings can become useless when in the presence of electromagnetic fields generated by power lines. Research was conducted to fully characterize the interference. Research on notch filter structures and adaptive filter algorithms has been carried out. The lattice form filter structure was chosen for its inherent stability and performance benefits. A new adaptive filter algorithm was developed targeting a hardware implementation. The algorithm used techniques from several other algorithms that were found to be beneficial. This work developed the hardware implementation of a lattice form adaptive notch filter to be used for the removal of power line interference from electrocardiogram signals. The various design tradeo s encountered were documented. The final design was targeted toward multiple field programmable gate arrays using multiple optimization efforts. Those results were then compared. The adaptive notch filter was able to successfully track and remove the interfering signal. The lattice form structure utilized by the proposed filter was verified to exhibit an inherently stable realization. The filter was subjected to various environments that modeled the different power line disturbances that could be present. The final filter design resulted in a 3 dB bandwidth of 15.8908 Hz, and a null depth of 54 dB. For the baseline test case, the algorithm achieved convergence after 270 iterations. The final hardware implementation was successfully verified against the MATLAB simulation results. A speedup of 3.8 was seen between the Xilinx Virtex-5 and Spartan-II device technologies. The final design used a small fraction of the available resources for each of the two devices that were characterized. This would allow the component to be more readily available to be added to existing projects, or further optimized by utilizing additional logic. Advisors/Committee Members: Phillips, Daniel.
