Full textENGLISH ABSTRACT: This business plan is a document focussing on creating a business which truly embrace the "New Economy", and by using technology, crafting a strategy which can ensure that the company become successful, and a market leader in the field of civil engineering. The plan focuses on two separate entities. Firstly, building a business by using current techniques in evaluating the industry, developing an initial strategy, and setting the tone for crafting a strategy in the future which will fulfil the goals and objectives of the company, thereby reaching it's initial vision. It use a combination of analysis, creativity, and learning to develop a market leader which has the main focus of being innovative, serving it's clients with service quality, becoming the leader in it's field. A key success factor interaction diagram was developed and combined with an industry value chain to change the operational process into a new market orientated process enabling the company to achieve it's goals. Secondly, the focus is to create wealth for its stakeholders. In that regard the current system in the engineering industry was challenged. New operational processes were developed which is in line with the company vision and mission. These processes was correlated with the financial structure and projections made to ensure that the crafting of the strategy will be done in a systematic way, but always focussing on the goals and objectives of the company. Finally, an implementation plan is developed which is a crucial action plan to ensure success in the future.
AFRIKAANSE OPSOMMING: Die doelwit van hierdie besigheidsplan is om die basis te lê om 'n suksesvolle markleier in die siviele ingenieurs bedryf te word. Dit is gebaseer op die beginsels van die "Nuwe Ekonomie". Tesame met daardie beginsels word tegnologie gebruik om 'n strategie te ontwikkel en te vorm soos wat die maatskappy groei. Die plan fokus op twee hoofdele. Eerstens, om 'n maatkappy van statuur te ontwikkel. Huidige analitiese tegnieke om die industrie te evalueer is gebruik om 'n basis strategie te ontwikkel. Hierdie basis strategie sal dan uitgebrei word soos wat die maatskappy ontwikkel deur te fokus op sy doelwitte en sy visie. Deur analise, kreatiwiteit en kundigheid te kombineer word gepoog om te fokus op innovering en kwaliteit wat die kwaliteite is wat benodig word om 'n mark leier te word. 'n Sleutel sukses faktor interaksie diagram is ontwikkel wat tesame met 'n industrie waarde ketting gebruik is om die huidige operasionele prosesse te verander in nuwe mark gerigte prosesse. Die stelsel is die fondasie wat gelê word om die maatskappy doelwitte te bereik. Tweedens, word daar gefokus om rykdom te skep vir die aandeelhouers asook die maatskappye wat deel vorm van die lCM netwerk. Die huidige stelsels in die industrie was ge-evalueer en afgebreek totdat nuwe stelsels ontwikkel is wat inpas in die visie en missie van die maatskappy. Dit is gekorreleer met 'n finansiële model en inkomste en uitgawe projeksies vir die toekoms. Die projeksies is gebaseer op 'n geleidelike ontwikkeling van die stelsels totdat daar na drie jaar 'n gevestigde wereldklas stelsel in plek is. Laastens word afgesluit met 'n aksie-plan wat noodsaaklik is vir effektiewe implimentering van die besigheidsplan.

Full textThe purpose of this study is to implement, test and apply a Maximurn Likelihood Classifier (MLC) and a userfriendly contextual Markovian classifier, which use the distributions most appropriate to the Synthethic Aperture Radar (SAR) data. This study presents the main distributions to the SAR data and how several of these distributions arise from the multiplicative model. In order to achieve the proposed aim and to allow future applications of the developed methodology, the implementations have been done in a integrated system for SAR data processing, classification and analysis, with a structure which allows the addition of other models and techniques. The developed system is based on the statistical properties of the data and, besides the necessary functions for the classification, it also allows the determination of the basic statistics of the classes' radiometries, the Chi-Square goodness-of-fit test in order to choose the most suitable distributions for these radiometries, the classification itself, and the evaluation of the results with the Kappa coefficient of agreement for the error matrices. The implemented contextual classifier is the Iterated Conditional Modes (ICM) algorithm. Its formulation for the parameter estimation was done for 8- and 12-coordinate neighborhoods. Tests have been done for the discrimination of three classes in SAR-580 and JERS-l images with different numbers of looks. The analysis of the results indicates that a more precise classification is achieved by using the distributions which are the most suitable for the classes, when compared to those obtained through the classic method that uses Gaussian distributions. Another conclusion is that the ICM algorithm presents results which are always superior to those obtained through the MLC classification, whichever distributions these radiometries may have. The classifications obtained from the ICM have Kappa values that are usually twice than those obtained with the MLC method. Therefore, when using the ICM algorithm, it is possible to achieve good results in the discrimination of classes such as primary forest, regeneration, and deforestation in rainforest areas, as it is the case of the JERS-l images used in this study. The developed system has also some operations which assist the classification of images in general (color table modification and edition, histogram equalization, sample manipulation, decorrelation of observations, arithmetical operations, etc.), and other operations specific for SAR images (speckle filtering, equivalent number of looks estimation, selection of image type and modelling, etc.).

Resumo: Esse trabalho surge com o objetivo de compreender as possíveis causas da mudança no discurso cristão evangélico com relação à sexualidade e às práticas sexuais; tendo como hipóteses que ela poderia ocorrer pela atuação de um líder carismático ou pela racionalização provocada por uma mudança de fundamento da ação, que poderia ser a mudança da ação tradicional para uma ação racional com relação a fins ou racional com relação a valores. Ainda, buscou-se identificar a pertinência da Teoria do Reconhecimento para a análise de processos de mudança social. Para tal, utilizou-se pesquisa qualitativa na Igreja da Comunidade Metropolitana da cidade de São Paulo, com observação de cultos e eventos, pesquisa documental nos sites da denominação, coleta de entrevistas concedidas pela liderança e vídeos na internet. Como fundamento teórico-metodológico utilizou-se uma reconstrução da Teoria do Reconhecimento Social de Axel Honneth, buscando suas origens na Teoria da Racionalização de Weber, e passando pelo que se pode denominar gramática moral de Habermas. Ao final da pesquisa percebeu-se que a transformação do discurso religioso na denominação estudada se dá pela mudança de uma ação tradicional em direção a uma ação racional com relação a valores, indicador de uma racionalização cultural na sociedade contemporânea e, mais especificamente, de uma racionalização da fé. Também evidenciou-se que a Teoria do Reconhecimento Social é pertinente para a análise de processos de transformação social.
Abstract: This work emerges with the aim of understanding the possible causes of change in the evangelical christian discourse regarding sexuality and sexual practices; having as hypotheses that the change could occur by an action from a charismatic leader or by the rationalization provoked by a shift of action's grounds, which in this case could be the change of the traditional action for an action that would be or a rationally purposeful action or a value rational action. Furthermore, it was sought to identify the efficacy of the Theory of Recognition for the analysis of social change's process. For this purpose, qualitative research was used in the Metropolitan Community Church of São Paulo city, with observation of cults and events, documentary research on the sites of the denomination, collection of interviews granted by the leadership and videos on the Internet. As a theoretical-methodological bases, a reconstruction of the theory of social recognition of Axel Honneth was carried out, seeking its origins in the theory of rationalization of Weber, and passing through a called moral grammar of Habermas. At the end of the research it was perceived that the transformation of the religious discourse in the denomination studied was due to the change from a traditional action to a value rational action, which indicates a cultural rationalization in contemporary society and, more specifically, a rationalization of faith. It was also evidenced that the theory of social recognition is effe... (Complete abstract click electronic access below)

In Indian Classical Music (ICM), the Raga is a musical piece's melodic framework. The Raga is a unique concept in ICM, not fully described by any of the fundamental concepts of Western classical music. The Raga provides musicians with a melodic fabric, within which all compositions and improvisations must take place. Raga recognition refers to identifying the constituent Raga in an audio file, a challenging and important problem with several known prior approaches and applications in Music Information Retrieval. This thesis presents a novel approach to recognizing Ragas by representing this task as a document classification problem, solved by applying a deep learning technique. A digital audio excerpt is processed into a textual document structure, from which the constituent Raga is learned. Based on the evaluation with third-party datasets, our recognition approach achieves high accuracy, thus outperforming prior approaches.

Nowadays deindustrialization underway in economies that have not yet reached a high per capita income is the main theme in debates. Several studies were conducted to Brazil on this subject, but the Northeast still lacks analysis in this area. The central hypothesis of this study is to verify ig the Northeast economy was deindustrialized in the period 1991-2012, from the continued growth of commodities in totalexports couopled with the highest share of products with higher technological content in the imports. The analysis was carried out by using data on the trade balance, exports and imports, registering the share of commodities and industrial products, according to the classification adopted by OECD and MDI C (high, medium-high, medium-low, low-tech and unprocessed products), the value added by industry, the share of manufacturing employment and total income (GDP). To this end, we calculated indicators foreign trade (Export Concentration Index-ICX, Concentration Index of Import-ICM, Revealed Comparative Advantage Index over the trade balance-VCR, simple rate of coverage of imports and TC-Index of intra-industrytrade-CII and an econometric model was regressed to verify traces of deindustrialization in relation to industrial production. The results indicate that the northeast export tariff undergoes a reprimarization that, when associated with the increased presence of industrial products with higher technological content of imports, show signs of deindustrialization. However, it is not possible to come to the conclusion that the northeast economy suffers the dutch disease because signs of loss of importance on the industrial sector in total did not appear on the analysis of industrial employment and of the value added by industry in the totaleconomy. There, such results corroborated with the econometric model regressed. However, some industries (textile, clothing and accessories and machinery, equipment and material) showed a decreasing trend in the evolution of the physical industry production index, which may indicate a kind of loss.
Nos dias atuais, é tema dos principais debates a desindustrialização em curso nas economias que ainda não atingiram alta renda per capita. Vários estudos foram realizados no Brasil sobre o assunto, mas a região Nordeste ainda carece de análises nessa área. A hipótese central deste estudo é verificar se a economia nordestina se desindustrializou no per5íodo 1991-2012, com o crescimento contínuo de commodities na pauta de exportações, aliado à maior participação de produtos de conteúdo tecnológico mais relevante na pauta de importações. A análise foi realizada fazendo uso de dados da balança comercial, exportação e importação, registrando a participação das commodities e dos produtos industriais segundo a classificação adotada pelo MDIC e OCDE (Ala, méida-alta, média-baixa, baixa intensidade tecnológica e produtos não industrializados), do valor agregado pela indústria, pela participação do emprego industrial no total e a renda (PIB). Para tal fim, foram calculados indicadores do comércio exterior (Índice de Concentração das Exportações-ICX, Índice de Concentração das Importações-ICM, Índice de Vantagem comparativa Revelada em relação ao saldo comerciakl-VCR, Taxa simples de Cobertura das importações-TC e o Índice de Comércio Intraindústria-CII) e regredido um modelo econométrico para verificar vestígios de desindustrialização concernente à produção industrial. Os resultados indicam que a pauta de exportação nordestina passa por uma reprimarização, que associada à maior presença de produtos industriais com maior conteúdo tecnológico nas importações apresenta sinais de desindustrialização. Não é possível concluir, no entanto, que a economia nordestina padeça da doença holandesa, pois, na análise do emprego industrial e do valor adicionado pela indústria no total da economia, não apareceram sinais de perda de importância do setor industrial no total, resultados esses corroborados pelo modelo econométrico regredido. Alguns segmentos industriais (têxtil, vestuário e acessórios, máquinas, aparelhos e materiais elétricos) expressam, contudo, uma tendência decrescente na evolução do índice de produção física industrial, o que pode indicar perda relativa desses ramos especificamente.

Super resolution image reconstruction consists in using a set of low resolution images from the same scene to generate a high resolution estimate of the original scene. For that purpose, all the observed low resolution images need to have sub-pixel displacements among each other. In this way, there is more than just the same information replicated in each image and then the uncertainty inherent to the displacements can be used as additional information to increase the spatial resolution. This master s thesis proposes a Bayesian approach for the super resolution reconstruction problem using Markov Random Fields and the Potts-Straus model for the image characterization. Therefore, it is possible to incorporate previously known context spatial information about the high resolution image to be estimated. Moreover, a discontinuity adaptive ICM algorithm was used to estimate the maximum a posteriori solution. Using an initial high resolution estimate constructed from the registration and interpolation of all the observations made it possible to reconstruct an image that respected the initially presented discontinuities. We also observed that the resulted high resolution image hold finner details when compared to the initial estimation.
A Reconstrução por Super Resolução consiste em, utilizando várias imagens de baixa resolução da mesma cena, gerar uma aproximação da cena original, que possua resolução espacial mais alta que a presente em qualquer uma das imagens observadas. Para isso, tais imagens devem possuir algum tipo de deslocamento da ordem sub-pixel uma em relação às demais, de forma que não exista apenas a mesma informação replicada em todas as imagens. Assim, a incerteza inerente a tais deslocamentos pode ser usada como informação adicional no aumento de resolução. Nesse contexto, esta pesquisa propõe uma abordagem Bayesiana do problema, utilizando Campos Aleatórios de Markov e o Modelo de Potts-Strauss na caracterização das imagens. Isso torna possível a imposição de informações espaciais de contexto conhecidas a priori da imagem de alta resolução a ser estimada. A estimativa de Máximo a Posteriori (MAP) de alta resolução é encontrada por meio do algoritmo Iterated Conditional Modes (ICM) adaptativo a descontinuidades. Dessa forma, utilizando como estimativa inicial de alta resolução a imagem resultante do registro e interpolação das imagens de baixa resolução observadas, foi possível reconstruir imagens de maior resolução que respeitassem as descontinuidades inicialmente presentes, e que apresentassem maior riqueza de detalhes.

Full textDie Gattung Legionella besteht aus opportunistischen Pathogenen, die Auslöser für die schwere Lungenentzündung Legionärskrankheit sind. Die Legionella-Spezies L. longbeachae sowie L. pneumophila vermehren sich intrazellulär in humanen alveolaren Makrophagen sowie in aquatischen oder im Boden lebenden Amöben. Ein vom endoplasmatischen Retikulum (ER) abstammendes Kompartiment ist notwendig für die intrazelluläre Replikation. Diese Nische wird als „Legionella-containing vacuole“ (LCV) bezeichnet. Die Bildung der LCV benötigt ein „intracellular multiplication/defective in organelle transport“ (Icm/Dot) Typ IV Sekretionssystem (T4SS), das Effektorproteine in die Wirtszelle transportiert. Zurzeit sind über 100 vermutete Effektorproteine für L. longbeachae und etwa 300 Effektorproteine für L. pneumophila beschrieben. Im Verlauf eines Reifungsprozesses kommuniziert die LCV mit endosomalen Vesikeln, verhindert eine Fusion mit den Lysosomen und fusioniert mit dem ER. Phosphoinositide wie das PtdIns(4)P wurden auf der LCV gefunden. Diese dienen als Bindestellen für die durch das Icm/Dot translozierten Effektorproteine wie das SidCLpn und sein paraloges Protein SdcALpn. In einer früheren Studie wurde in einem Phosphoinositid-Pulldown Experiment das 73 kDa Effektorprotein SidM aber nicht das 106 kDa Protein SidCLpn als Bindepartner von PtdIns(4)P nachgewiesen. Wir konnten in einem Phosphoinositid-Pulldown Experiment mit L. longbeachae Lysat zeigen, dass das 111 kDa homologe Protein von SidCLpn SidCLlo der Bindepartner von L. longbeachae für PtdIns(4)P ist. Ein 19 kDa großes SidCLlo- Fragment im Bereich der Aminosäuren 609 bis 782 konnte identifiziert werden, das für die Bindung von SidCLlo an PtdIns(4)P notwendig ist. Interessanterweise liegt die früher beschriebene 20 kDa große P4C Domäne von SidCLpn in der gleichen Region. Durch Inkubation von GST-gekoppelten SidCLlo_P4C-Proteinen mit L. pneumophila Zellhomogenat konnten wir zeigen, dass SidCLlo_P4C die Vakuole von L. pneumophila homogen dekoriert. Daher kann SidCLlo_P4C genauso wie das SidCLpn_P4C als LCV Marker benutzt werden. Die P4C Domänen besitzen eine Sequenzhomologie von 45% und SidCLlo und SidCLpn zeigen eine Sequenzhomologie von 40%. Mittels zirkularer Dichroismus Messung konnte gezeigt werden, dass die beiden Proteine ähnliche Sekundärstrukturen besitzen. Mittels isothermer Titrationskalorimetrie konnten wir zeigen, dass SidCLlo eine 3.4-fach höhere Bindeaffinität zu PtdIns(4)P besitzt als SidCLpn. In infizierten RAW 264.7 Makrophagen konnte wir zeigen, dass L. longbeachae nicht nur sein eigenes endogen produzierten SidCLlo sondern auch ein heterolog exprimiertes SidCLpn in einer Icm/Dot abhängigen Art und Weise auf die LCV transloziert. Frühere Studien zeigten, dass in einer sidC-sdcALpn Deletionsmutante die ER Rekrutierung zu der LCV in infizierten D. discoideum Zellen beeinträchtigt ist. Wir konnten zeigen, dass die heterologe Produktion von SidCLlo diesen Rekrutierungsfehler komplementieren kann, ebenso wie Plasmid-kodiertes SidCLpn oder SdcALpn. Die Deletion vom Gen sidCLlo in L. longbeachae führt ebenfalls zu einer verminderten Rekrutierung von ER-Markern zur LCV in infizierten D. discoideum. Dieser Effekt konnte durch eine Produktion von SidCLlo, SidCLpn und SdcALpn komplementiert werden. Die SidC Deletionsstämme von L. longbeachae oder L. pneumophila replizierten in Acanthamoeba castellanii wie die entsprechenden Wildtyp-Stämme, aber in direkter Konkurrenz wurden die Deletionsmutanten von den Wildtyp-Stämmen verdrängt. Insgesamt scheinen trotz der geringen Sequenzidentität und der höheren Bindeaffinität von SidCLlo im Vergleich zu SidCLpn zu PtdIns(4)P beide Effektorproteine ähnliche Funktionen im Infektionsweg von Legionella wahr zu nehmen. Für die Charakterisierung von L. longbeachae-enthaltenden Vakuolen in einer Proteomanalyse müssen LCVs aus D. discoideum oder RAW 264.7 Makrophagen isoliert werden. Endogenes SidCLlo oder heterolog produziertes SidCLpn wurden als Vakuolen- Marker für die Isolation von L. longbeachae-enthaltenen Vakuolen verwendet. L. longbeachae-enthaltene Vakuolen wurden in einer Immunaffinitätsaufreinigung mit Hilfe spezifischer Antikörper gegen SidCLlo oder SidCLpn isoliert. Weitere Studien zielen auf die Verbesserung der Vakuolen-Isolation von L. longbeachae, um das Proteom dieser LCV zu charakterisieren.

Full textWith new technological advances in functional brain imaging and theoretical progress in the knowledge of the different neurophysiologic processes linked to cognition, the last two decades have seen the emergence of Brain-Machine Interfaces (BCIs) allowing a person to observe in real-time, or with a few seconds delay, his own cerebral activity. Clinical domain in general, and more particularly neuropsychology and pathologies leading to heavy motor handicaps, for which potential applications are numerous, whether therapeutic or for functional rehabilitation, has been a major driver of research on this new field of real-time neurosciences. Among these applications, neurofeedback, or neurotherapy, which aims the subject to voluntary control some aspects of his own cerebral activity in order to amplify or reduce them in a therapeutic goal, or for cognitive optimization, represents a promising technique, and an alternative to drug treatments. However, validation of this type of intervention and understanding of involved mechanisms are still in their infancy. Neurofeedback training is often long, up to several weeks. It is therefore very likely that this type of rehabilitation is seeking brain plasticity phenomena that are part of slow dynamics, and thus require a relatively long drive to achieve the desired long-term effects. However, other disturbing elements that could add up to the cause of the difficulty of learning and long training sessions required to achieve the expected results. Among them, the disturbances that come from recorded signal distortions, or artifactual elements that are not part of the signal of interest, are a first potential cause. The lack of functional specificity of the signal returned to the subject could be a second one. We have developed signal processing methodological tools to improve the robustness to artifacts and electromagnetic noise of EEG signals analysis, the main brain imaging technique used so far in the field of neurofeedback and BCIs. On the other hand, if one looks at the issue of functional specificity of the signal presented to the subject, studies using functional MRI or source reconstruction methods from the EEG signal, which both provide signals having a better spatial specificity, suggest improvements to the speed of learning. Seeing Independent Component Analysis as a potential tool to increase the spatial specificity and functional contingency of the feedback signal presented to the subject, we studied the stability of Independent Component Analysis decomposition of the EEG across different recording sessions conducted on the same subjects. We show that these decompositions are stable and could help to increase the functional specificity of BCI training. We also worked on the implementation of a software tool that allows the optimization of experimental protocols based on neurofeedback to use these independent components to reject artifacts or to extract brain activity in real-time. These tools are useful in the analysis and characterization of EEG signals recorded, and in the exploitation of their results as part of a neurofeedback training. The second part focuses on the development of neurofeedback protocols and the impact of learning. We first describe the results of a pilot study which seeks to evaluate the impact of a neurofeedback protocol based on the Mu rhythm control on healthy subjects. The behavioral changes were studied using a stop signal paradigm that indexes the attentional abilities and inhibition of motor responses on which the BCI training can possibly have influence. To conclude this section, we present a new tool for immersive interactive brain training, education, art and entertainment that can be used to assess the impact of immersion on learning during a neurofeedback protocol. Finally, prospects for methods and results presented are discussed in the context of next-generation BCI development which could take brain activity complexity into account. We present the latest advances in the study of certain aspects of the neural correlates associated with two mental states or classes of mental states that could be described as antagonistic with respect to the control of attention: meditation and mind wandering, for their integration in the longer term in an BCI training using neurofeedback

Full textBrain-machine interfaces (BMIs) left the realm of science fiction in the 1970s with Jacques Vidal's reflection on the feasibility of using electroencephalogram signals as a means of communication between the brain and external devices. During the development of this research field, various approaches have been explored to create a true interface between the brain and a machine. The methods of data acquisition have taken different forms, and with the improvement of computer capabilities and the advent of machine learning, methods to classify brain data have become more refined, capable of capturing complex information from brain data. A promising avenue to assist patients lies in the rehabilitation process following a stroke. By performing movements or providing feedback to patients about their brain activity, it is possible to help their brains adapt to neuronal deficits and aid them in overcoming their impairments. In this context, BMIs act as a support, like crutches, during the rehabilitation period. However, in this context, one challenge is to create differentiable brain patterns at the EEG level. To create these patterns, cognitive tasks that modify brain activity profiles are relied upon. One such task is motor imagery of limb movements, where subjects imagine movements without executing them. This particular task is unfamiliar to many and thus becomes complex to execute. One way to assist subjects in performing it is to provide evocative feedback in the BMI context, such as a robotic arm. Nurturing a sense of control over the arm and its movements helps elicit more differentiable brain patterns. Nevertheless, due to current limitations in the degree of control permitted by BMI systems, full control of a robotic arm is not yet possible. A solution is to couple the BMI with another technology to increase the degree of control and reinforce subjects' sense of agency over the arm. Among the technologies offering insights into subjects' intentions without requiring movement, the eye tracker appears to be an elegant solution. The integration of these two components creates a hybrid BCI system capable of intuitively controlling the arm. This hybridization has been demonstrated as a proof of concept in the BMI field, but the impact of integrating these modalities on the brain remains to be studied. A better understanding of how to shape the interaction between the eye tracker, BMI, and robotic arm would shed light on why good performances are obtained and how to elicit these discriminant brain patterns. The work in this thesis focused on creating an experimental platform that intertwines these different modalities to establish robust control over the arm. Through an experimental protocol, we assessed how to define the interaction through in-depth analysis, covering the system's pure performance and the physiological and neurophysiological responses of subjects. We found that consistency is crucial in the interaction, and we demonstrated the importance of movement in eliciting brain responses in this particular context. Our work paves the way for a better understanding of the brain's dynamics in controlling external devices in a multimodal setup. Additionally, we propose a new framework for controlling a robotic arm using a hybrid BCI. The thesis is structured into five chapters, covering the overall context of BMIs, the development of the experimental platform, the results from the experimental protocol and their discussion, and finally, a general conclusion

(GMTI) techniques that have been studied for the last twenty years to overcome this problem. In this thesis, the simulation of some of these techniques in a realistic environment and the comparison of their performances are discussed. In this work, a GMTI simulator is developed to generate the environment containing the clutter and the noise signals, to locate and simulate the targets in this environment and to apply the GMTI techniques on the raw data generated by the simulator. The generation of the clutter signals including the internal clutter motion (ICM) for different types of clutter distributions is one of the most important parts of this thesis. The GMTI techniques being investigated throughout this thesis are &ldquo

(DPCA), &ldquo
Along-Track Interferometry&rdquo
(ATI), &ldquo
Adaptive DPCA&rdquo
, &ldquo
Pre-Doppler Sigma-Delta STAP&rdquo
and &ldquo
Post-Doppler Sigma-Delta STAP&rdquo
techniques. These techniques are compared according to their clutter suppression and target detection performances under different environmental conditions.

Full textThe work of this thesis focuses around two axes: the classification for the mapping of land cover and the extraction of roads from satellite and aerial images. The first axis aims to propose a method of classification which takes in account the spatial information contained in a satellite image. Thus, we developed a method of Markov classification with the search for the optimal solution by an ICM (Iterated Conditional Mode) algorithm. This method is parameterized by a new factor of temperature, this parameter will allow, first, to rule the tolerance of the disadvantageous configurations during the evolution of the classification process, and secondly, to ensure the convergence of the algorithm in a reasonable time of calculation. In parallel, we introduced a new contextual constraint of the segmentation in the algorithm. This constraint will allow, over the iterations, to refine the classification by accentuating the detected details by the segmentation contours. The second axis of this thesis is the extraction of roads from satellite and aerial images. We proposed a completely automatic methodology with an extraction system in blocks which act separately and independently on the image. The first block operates a directional adaptive filtering, allowing detecting roads in each window of the image according to the dominant directions. The second one applies segmentation, and then selects the segments representing roads according to a criterion of the segment form. These two blocks provide a different type of information on the studied image. These results are then complemented with a third block to generate an image of the road network. The performances of the proposed methodologies are verified through examples of satellite and aerial images. In general, the experimental results are encouraging
