The urban growth in Santa Maria, presents an expansion of irregular land occupation, a fact that provides social inequality and conflicts in the urban land occupation, as well as excluding factors. This study aims to present a general portrait of the process of occupation in the Fazenda Santa Marta, in Santa Maria, including its 7 (seven) settlements which are: Loteamento Alto da Boa Vista, Loteamento Marista, Loteamento Sete de Dezembro, Loteamento Dez de Outubro, Loteamento Dezoito de Setembro, Loteamento Pôr do Sol, and Loteamento Núcleo Central. Therefore, the temporal analysis for this study starts with the 1991 occupation, rescuing its history process, as well as the evidence indicating that a certain amount of poverty is associated to the lack of infrastructure. This way, there is a focus on the analysis of the social spatial aspects of the evolving process, on the historic process and on the understanding of social movements, as well as to highlight nowadays the context of the settlements. The methodology used had a theoretical basis limited by the studied area and a cartographic base. With this bibliographic research, it was possible to identify the current structure of Bairro Nova Santa Marta, and also how the process of irregular occupation is understood within it. In this process, predominates the expansion of the areas and an increase of poverty and need for basic services, because the population of the settlements is growing considerably, and the poverty does not manifest only in the lack of basic social services, but in the absence of sociability and environmental resources that can could help the residents. Finally, all the progress of men studied here shows the characteristic urban lifestyle and everyday life, of contemporary life. / O crescimento urbano, da cidade de Santa Maria, apresenta um quadro de expansão de áreas ocupadas de forma irregular, fato que tende a determinar desigualdades e conflitos na ocupação do solo urbano, bem como fatores de exclusão. Este estudo tem por finalidade expor um panorama geral do processo evolutivo da área ocupada na Fazenda Santa Marta, no município de Santa Maria abrangendo seus 7 (sete) loteamentos sendo eles: Loteamento Alto da Boa Vista, Loteamento Marista, Loteamento Sete de Dezembro, Loteamento Dez de Outubro, Loteamento Dezoito de Setembro, Loteamento Pôr do Sol, Loteamento Núcleo Central. Desse modo, o recorte temporal para este trabalho inicia com a ocupação em 1991, resgatando seu processo histórico, bem como a evidência de que há índices de pobreza associados a falta de infraestrutura. Assim, privilegiou-se analisar os aspectos socioespaciais do processo de evolução, conhecer o processo histórico e compreender aspectos dos movimentos sociais, bem como salientar o contexto atual dos loteamentos. A metodologia constituída pela fundamentação teórica delimitada pela área estudada, bem como a base cartográfica. Por meio dessa pesquisa, de caráter bibliográfico, foi possível, identificar como se apresenta atualmente a estrutura do Bairro Nova Santa Marta, bem como é entendido nele o processo de ocupação irregular. Nesse processo, há predomínio na expansão das áreas, aumento da pobreza e carência dos serviços básicos, visto que a população nos loteamentos aumenta consideravelmente. As condições precárias do bairro não se manifestam somente pela falta dos serviços básicos e sociais, mas também na falta de recursos de sociabilidade, e ambientais que venha atender os moradores ali residentes. Finalmente, todos os avanços do homem estudados neste trabalho denotam formas da vida e do cotidiano urbano, característicos da problemática urbana.

The text aims to identify aspects that should be considered in preparing the State’s institutions to effectively combat human trafficking of a transnational nature. It addresses four main issues. First, it notices the specific problems of foreign human trafficking victims, which could be confused or overlapped with other categories, such as migrant smuggling and illegal migrant status. Subsequently, it develops three fundamental arguments that give primacy to their status as victims of human trafficking and their specialized attention from a human rights perspective. Thirdly, it provides guidelines on the elements that should constitute this approach from the specific rights of foreign victims of human trafficking. Finally, the Peruvian legal and institutional framework is analyzed, as well as its possibilities and challenges for adequate attention to foreign victims of trafficking. / El texto apunta a determinar los aspectos que deben ser considerados para perfeccionar el funcionamiento del aparato estatal con el fin de luchar efectivamente contra la trata de personas de carácter transnacional y para orientarlo por los principios propios de un enfoque de derechos humanos con respecto a la víctima de trata de personas. Aborda cuatro puntos centrales. Primero, advierte la problemática particular de las víctimas de trata extranjeras, al ser proclive su confusión o superposición con otras categorías, como la de tráfico de migrantes y migrante en condición irregular. Posteriormente, se desarrollan tres argumentos fundamentales que otorgan primacía a su condición de víctima de trata y a su atención especializada desde un enfoque de derechos humanos. Como tercer punto, se brindan directrices sobre los elementos que deben componer este enfoque, a partir de los derechos específicos de víctimas de trata extranjeras. Por último, se analiza el marco normativo e institucional peruano, y sus posibilidades y retos para lograr una atención adecuada a las víctimas de trata extranjera.

Uma LT possui como elementos básicos: cabos, isoladores e torres. O espaço no solo ocupado por esses elementos e entorno deve ser respeitado frente às diversas formas de ocupação. Esta área protegida é denominada Faixa de Servidão. A faixa de servidão, como território ocupado com potencial de geração de riscos à população, têm inúmeras restrições quanto à sua utilização, dada sua destinação: proteger o sistema elétrico e a sociedade. Sua largura varia em função da tensão dos cabos. Para tensões de 230 e 500 kV (kilovolts) a largura da faixa de servidão é respectivamente de 50 e 65 metros. A ocupação e conservação da faixa de servidão de forma adequada possibilitam maior segurança para as pessoas e bens localizados na vizinhança, bem como maior rapidez na localização de anomalias e na manutenção na LT. Ocupações das faixas de servidão, que não estejam contempladas no projeto de instalação da LT, são consideradas ocupação irregular ou invasão e devem ser identificadas e removidas. Atualmente existem dados de sensoriamento remoto de média e alta resolução espacial que podem auxiliar no estudo do uso e cobertura do solo. Neste contexto, esta pesquisa tem como objetivo desenvolver uma metodologia, a partir de dados de sensoriamento remoto (CBERS-2B/HRC e SRTM), para identificar áreas invadidas e suscetíveis à ocupação irregular em faixa de servidão de LT. Para isso foram aplicadas técnicas de segmentação, classificação de imagem e desenvolvido modelos matemáticos usando parâmetros definidos nesta pesquisa. A área de estudo é a faixa da LT 230 kV Ibicoara/Brumado, localizada no estado da Bahia. A pesquisa caracterizou de forma abrangente e eficaz, a temática de LT e faixa de servidão, envolvendo aspectos técnicos, ambientais e de segurança, e contextualizou o sensoriamento remoto relacionando-o com o tema, envolvendo sistemas sensores e aplicações. Os resultados do estudo mostraram-se eficientes na observação/fiscalização do quadro de ocupação da faixa de servidão em locais específicos, sendo possível antecipar ocorrência de invasões, auxiliando na gestão de rede transmissão de energia elétrica. / The transmission lines (TL) are constructions intended for the transport of electricity from the generating sources to consumption centers. A TL has as basic elements: cables, insulators and towers. The land space occupied by these elements and surroundings must be respected across the various forms of occupation. This protected area is called right of way. The right of way as a potential risk area for population has numerous restrictions for its use, given their destination: protect the electrical system. Its width varies depending on the tension of the cables. For voltages of 230 and 500 kV (kilovolts) the width of the right of way is respectively 50 and 65 meters. The occupation and conservation of the right of way enables greater security for people and property located in the surroundings, as well as greater speed in detecting anomalies and for the maintenance of the TL. Occupations in the right of way, which are not included in the TL installation project, are considered illegal occupation or invasion and must be identified and removed. Currently there are remote sensing data of medium and high spatial resolution that can support the study of land use and land cover. In this context, this research aims to develop a methodology, based on remote sensing data (CBERS-2B / HRC and SRTM) to identify areas invaded and susceptible to irregular occupation in the right of way. Therefore, segmentation techniques, image classification and developed mathematical models using parameters defined for this search were applied. The study area is the right of way of the TL 230 kV Ibicoara / Brumado, located in the state of Bahia. This study used a comprehensive and effective way to characterize the issues related to TL and its right of way, considering technical, environmental and safety aspects, and contextualized remote sensing relating it to the subject, considering sensor systems and applications. The results of the study showed to be efficient in the observation / surveillance for the status of occupation of the right of way, in specific locations, making possible the anticipation of occurrence of invasions, giving more support for the management of power grid.

A intensa expansão urbana que vem ocorrendo, para além das fronteiras do município de são Paulo, sobretudo a partir da década de 70, está aliada à especulação imobiliária e à miséria de uma significativa parcela da população; isto faz com que o processo de ocupação do solo se dê, predominantemente, de forma desordenada e ilegal, especialmente, em áreas protegidas. Diante isso, investigou-se o caso do município de Mairiporã (localizado na zona norte da Grande São Paulo), que possui 80,13% de suas terras inseridas na área de proteção aos mananciais, além de abrigar o reservatório Paiva Castro, o qual faz parte do sistema Cantareira; principal manancial abastecedor da metrópole paulistana. Desse modo, a ocupação ilegal do solo, nesse município, torna-se um fator relevante de análise, destacando que esta ilegalidade está associada à transgressão da lei de proteção aos mananciais, bem como da lei federal de parcelamento do solo (Lei Lehmann). Para tanto, este estudo parte de uma análise político-institucional e sócio-econômica que permite a proliferação de loteamentos irregulares ou clandestinos na região metropolitana de São Paulo e segue para uma análise comparada entre dois loteamentos em Mairiporã (um irregular e outro clandestino) salientando aspectos: das condições de vida do morador; da percepção ambiental dos moradores acerca da área protegida com a qual interagem; e, por fim, da compreensão dos mesmos sobre a situação de ilegalidade em que se encontram. / The intense urban expansion, which is running beyond the borders of the district of São Paulo since the decade of the 70\'s, is associated with land speculation and a state of misery of a significant part of the population. Furthermore, the process of occupation happens in a disordered and illegal way, specially in protected areas. Because of that, the case of the district of Mairiporã (north of the metropolitan region of São Paulo) was studied. There, 80,31% of the district are included into the protection area of water resources, as well as the water reservoir Paiva Castro, which takes part in the Cantareira system; the principal water resources supplier of the metropolitan area of São Paulo. Therefore, the illegal occupation of land, in the district of Mairiporã, turns out to be relevant to analyze, pointing out that the illegality is associated with transgressions of the law for protection of water resources as well as with the federal law of land parcelation (Lehmann Law). The study begins with an analysis of the institutional, political and socio-economic situation which allowed the proliferation of irregular land lots or clandestine in the metropolitan region of São Paulo. This analysis is followed by a comparison between two land lots in Mairiporã (irregular and clandestine) focussing on aspects of the living conditions of the residents, environmental perception in relation to the protected area they are interacting with, and finally, the understanding of theresidents of the state of illegality they encounter.

In the journey toward optimal spectrum usage, techniques and concepts such as Cognitive Radio and Dynamic Spectrum Access have enjoyed increasing attention in many research projects. Dynamic Spectrum Access introduces the need for real-time RF spectrum information in the form of Radio Environment Maps. This need motivates an investigation into a hybrid approach of sample measurements and spatial interpolation as opposed to using conventional propagation models. Conventional propagation models, both path-general and path-specific, require information of transmitters within the area of interest. Irregular Terrain Models such as the Longley-Rice model, further require topographic information in order to consider the effects of obstacles. The proposed spatial interpolation technique, kriging, requires no information regarding transmitters. Furthermore, Ordinary Kriging requires nothing other than measured samples whereas other kriging variants such as Universal Kriging and Regression Kriging can use additional information such as topographic data to aid in prediction accuracy. This dissertation investigates the performance of the three aforementioned kriging variants in producing Radio Environment Maps of received power. For practical and financial reasons, the received power measurement samples are generated using the Longley-Rice Irregular Terrain Model and are, therefore, simulated measurements. The experimental results indicate that kriging shows great promise as a tool to generate Radio Environment Maps. It is found that Ordinary Kriging produces the most accurate predictions of the three kriging methods and that prediction errors of less than 10 dB can be achieved even when using very low sampling densities. / MSc (Computer and Electronic Engineering), North-West University, Potchefstroom Campus, 2015

According to a recent report by the U.S. Senate Joint Economic Committee, the costs of domestic air traffic delays were estimated to be a staggering $41 billion in 2007. Of this, $19.1 billion was attributed to airline operating costs and $12 billion was attributed to passenger delays. In instances of irregular operations, an airline's primary objective is to get operations back to normal as quickly as possible while incurring minimal cost. Historically, airlines have prioritized recovering schedules for aircraft and crew before attempting to reaccommodate disrupted passengers. The literature has not examined how proactive movement of passengers can be used to mitigate the impact of irregular operations. This work bridges this gap by exploring how early standby fees (which influence customer behavior) can be utilized to improve operations. This research uses a variety of public and private data sources to construct a micro-level simulation to explore the impact that early standby pricing policies have on aggregate and average delay for disrupted passengers. Three distinct modules developed for use in the simulation have broader applications to the research community: (1) logic for a passenger reaccommodation algorithm; (2) a model that predicts the number of early standby passengers; and (3) a model to predict the probability a passenger misses a connecting flight. Preliminary results confirm the hypothesis that early standby pricing policies affect both profitability and operational performance. A simple example illustrates that an airline faces an important tradeoff when setting an early standby pricing policy: the early standby fee that maximizes an airline's profitability is different from the early standby fee that yields the lowest aggregate and average delay metrics for customers. This dissertation proposes a new product that remedies these competing objectives by improving them both simultaneously.

International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / A joint source-channel coding scheme (JSCCS) used in applications, like sending images, voice, music etc. over internet/ wireless networks, involves source coding to compress the information and channel coding to detect/ correct errors, introduced by the channel. In this paper, we investigate the unequal error protection (UEP) capability of a class of low-density parity-check (LDPC) codes in a JSCCS. This class of irregular LDPC codes is constructed from cyclic difference families (CDFs).

Wireless devices and applications have been an unavoidable part of human lives in the past decade. In the past few years, the global mobile data traffic has grown considerably and is expected to grow even faster in future. Given the fact that the number of wireless nodes has significantly increased, the contention and interference on the license-free industrial, scientific, and medical band has become severer than ever. Cognitive radio nodes were introduced in the past decade to mitigate the issues related to spectrum scarcity. In this dissertation, we focus on the interference and performance analysis of networks coexisting with cognitive radio networks and address the design and analysis of spectrum allocation and routing for cognitive radio networks. Spectrum allocation enables nodes to construct a link on a common channel at the same time so they can start communicating with each other. We introduce a new approach for the modeling and analysis of interference and spectrum allocation schemes for cognitive radio networks with arbitrarily-shaped network regions. First, for the first time in the literature, we propose a simple and efficient approach that can derive the distribution of the distance between an arbitrary interior/exterior reference point and a random point within an arbitrary convex/concave irregular polygon. This tool is essential in analyzing important distance-related performance metrics in wireless communication networks. Second, considering the importance of interference analysis in cognitive radio networks and its important role in designing spectrum allocation schemes, we model and analyze a heterogeneous cellular network consisting of several cognitive femto cells and a coexisting multi-cell network. Besides the cumulative interference, important distance-related performance metrics have been investigated, such as the signal-to-interference ratio and outage probability. Finally, the spectrum allocation and routing problems in cognitive radio networks have been discussed. Considering a wireless cognitive radio network coexisting with a cellular network with irregular polygon-shaped cells, we have used the tools developed in this dissertation and proposed a joint spectrum allocation and routing scheme. / Graduate

This dissertation examines multi-antenna transceiver design over flat-fading wireless channels. Bit Interleaved Coded Modulation (BICM) and MultiLevel Coded Modulation (MLCM) transmitter structures are considered, as well as the used of an optional spatial precoder under slow and quasi-static fading conditions. At the receiver, MultiStage Decoder (MSD) and Iterative Detection and Decoding (IDD) strategies are applied. Precoder, mapper and subcode designs are optimized for different receiver structures over the different antenna and fading scenarios. Under slow and quasi-static channel conditions, fade resistant multi-antenna transmission is achieved through a combination of linear spatial precoding and non-linear multi-dimensional mapping. A time-varying random unitary precoder is proposed, with significant performance gains over spatial interleaving. The fade resistant properties of multidimensional random mapping are also analyzed. For MLCM architectures, a group random labelling strategy is proposed for large antenna systems. The use of complexity constrained receivers in BICM and MLCM transmissions is explored. Two multi-antenna detectors are proposed based on a group detection strategy, whose complexity can be adjusted through the group size parameter. These detectors show performance gains over the the Minimum Mean Squared Error (MMSE)detector in spatially multiplexed systems having an excess number of transmitter antennas. A class of irregular convolutional codes is proposed for use in BICM transmissions. An irregular convolutional code is formed by encoding fractions of bits with different puncture patterns and mother codes of different memory. The code profile is designed with the aid of extrinsic information transfer charts, based on the channel and mapping function characteristics. In multi-antenna applications, these codes outperform convolutional turbo codes under independent and quasi-static fading conditions. For finite length transmissions, MLCM-MSD performance is affected by the mapping function. Labelling schemes such as set partitioning and multidimensional random labelling generate a large spread of subcode rates. A class of generalized Low Density Parity Check (LDPC) codes is proposed, to improve low-rate subcode performance. For MLCM-MSD transmissions, the proposed generalized LDPC codes outperform conventional LDPC code construction over a wide range of channels and design rates.
