As linhas de transmissão no Brasil formam uma imensa rede de transporte de energia elétrica denominada SIN (Sistema Interligado Nacional). Ao longo das áreas próximas às linhas existem corredores denominados faixa de passagem. Devido à alta tensão dos cabos energizados e aos riscos para a população e para o sistema, essas áreas têm restrições de uso. Contudo, sabe-se que, frequentemente, são registradas ocorrências de ocupações ilegais. O presente trabalho discute a questão das ocupações irregulares nas faixas de passagens das linhas de transmissão de energia elétrica em áreas urbanas no Brasil. Isto porque as variáveis que influenciam para ocorrência da infração estão localizadas preferencialmente nas cidades. A análise está focada nos fatores presentes nas adjacências das faixas de passagens. Foram identificadas três características propulsoras do descumprimento da regra: a tipologia do uso do solo, a associação das condições socioeconômicas e a densidade demográfica nas imediações dessas faixas. O estudo baseia-se nessas variáveis e faz uso das técnicas do geoprocessamento para a realização de uma série de tarefas necessárias para a execução do trabalho, como mapeamento do uso do solo, geração de buffer análise e produção de overlays. Os recursos das análises de agrupamento foram o meio usado para sintetizar os dados referentes à população, à renda e à escolaridade. O modelo desenvolvido foi aplicado e testado nos arredores da Linha de Transmissão 345 kV - Anhanguera-Guarulhos, situada na zona norte da cidade de São Paulo e que perpassa por áreas com diversos tipos de urbanização, diferentes níveis de renda, variadas classes sociais e muitos tipos de uso e ocupação do solo. / The Electric Power Transmission Lines in Brazil form an immense network of electricity transportation named the National Interconnected System (SIN). Along the nearby areas of the lines transmissions, there is a zone called line transmissions corridor. Due to the high-voltage of the power cables and the risks to the population and to the system, these areas have restrictions of use. However, it is known that illegal occurrences are frequently registered. The present work discusses the matter of irregular occupations in the line transmission corridors of the electric power transmission lines in urban areas in Brazil. It is because of the fact that the variables that influence this type of infringement are exceedingly present in cities. The focus of the analysis is on factors found in the vicinities of the lines transmission corridors. Three propelling characteristics of the rules non-compliance were identified: the soil use type, the association of socioeconomic conditions and the demographic density of the surrounding area. The study is based on these factors and uses geoprocessing techniques to perform a series of tasks required for the execution of this work, such as mapping the land use, generating the buffer analysis and producing the overlay analysis. The resources of the cluster analysis were used to synthesize data referring to the population, income and education. The developed model was applied and tested in the surroundings of the 345kV electric line transmission Anhanguera-Guarulhos, located in the northern part of the city of São Paulo, passing through areas with different types of urbanization, different income levels, various social classes and many types of land use.

The diploma thesis titled Interpretation of traffic accident analysis results in relation to related legal decision deals with the interpretation of legal decisions accidents with not giving right of way. The main goal of this thesis is to find an established line for assessing culpability for comparable accident situations. Before the analysis of the 230 court rulings measurement is performed to estimate the distance an speed, because it is closely connected with right of way. In the context of theoretical part is characterized by a right of way, an expert in criminal proceedings, the road traffic regulations, penalties and the factors that influence us while driving. The analytical part draws on 230 court rulings and 5 expert opinions provided by the Institute of Forensic Engineering of the Technical University in Brno. Conclusion of the analytical part an established threshold for assessing culpability for comparable accident situations is found.

Bibliography / Thesis (LLM (Public Law))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: Traditionally, the common law rule as interpreted by South African case law required that mutual consent be obtained in order to relocate a specified servitude of right of way. Since the Linvestment judgment, the legal position pertaining to the unilateral relocation of a specified servitude of right of way is that the location of an existing specified servitude of right of way may be altered unilaterally by the owner of the servient tenement. Unilateral relocation of a specified servitude of right of way will only be allowed if strict requirements are met, namely that the servient owner will be materially inconvenienced in the use of his property if the status quo is maintained; that the relocation will not prejudice the owner of the dominant tenement; and that the servient owner pays all costs incurred in the relocation of the servitude. In order to justify the departure from the common law, the court in Linvestment relied on historical argument, comparative law, and policy arguments to reach the conclusion that a servitude may be relocated unilaterally if it is in the interest of fairness, equity and justice. The court relied on section 173 of the Constitution, which entitles the courts to develop the common law. This decision of the Supreme Court of Appeal has far-reaching implications. A servitude is a limited real right to the property of another person which grants the holder of that right specific entitlements. South African law requires that registration in the deeds registry take place in terms of section 63(1) of the Deeds Registries Act 47 of 1937 as soon as a limited real right in immovable property is created or transferred. Once the servitude is registered, it will be enforceable against the owner of the servient tenement and all his successors in title. When the servient owner is allowed to relocate the servitude unilaterally, it will have the effect of undermining the limited real right that the dominant owner holds in the property in question. This thesis evaluates the extent to which the courts may change common law principles on the basis of fairness, justice and equity. The conclusion is that the policy grounds on which the court based its decision are convincing, as the law cannot remain rigid and needs to be continually changed in order to meet changing conditions. However, the comparative and historical reasons provided for the decision are insubstantial and unconvincing. The thesis points out that there are no historical grounds for the decision, but that more extensive and contextual comparative research does support the decision. This thesis considers the constitutional implications of a flexible legal approach to the unilateral relocation of a specified servitude of right of way and concludes that an approach that allows for unilateral relocation will not amount to an expropriation and will not establish an arbitrary deprivation either, provided that the requirements set out in the decision are applied strictly and that a court order is required for the relocation. / AFRIKAANSE OPSOMMING: Die tradisionele gemeenregtiglike beginsel rakende die verlegging van 'n gespesifiseerde reg van weg het vereis dat wannneer 'n roete eers vasgestel is, die eienaar van die dienende erf dit nie mag verander nie tensy hy toestemming verkry het van die eienaar van die heersende erf. Sedert die uitspraak in Linvestment, is die regsposisie dat die eienaar van die dienende erf wel die ligging van 'n serwituut eensydig mag verander. Die eienaar van die dienende erf sal slegs gemagtig wees om die servituut te verskuif onder omstandighede waar die huidige ligging van die serwituut wesenlike materiële nadeel vir hom meebring, die verskuiwing van die serwituut geen nadeel vir die eienaar van die heersende erf sal veroorsaak nie en mits die eienaar van die dienende erf die kostes wat verband hou met die verskuiwing van die serwituut sal dra. Die hof het op historiese, regsvergelykende en beleidsoorwegings gesteun om die gevolgtrekking te staaf dat 'n serwituut verkuif kan word, selfs al is dit teen die wens van die eienaar van die heersende erf. Die hof het ook beslis dat die howe die inherente bevoegdheid het om die gemenereg te ontwikkel ingevolge artikel 173 van die Grondwet. Die beslissing het verreikende implikasies. 'n Serwituut is 'n beperkte saaklike reg op die saak van iemand anders wat aan die reghebbende bepaalde genots- en gebruiksbevoegdhede ten aansien van daardie saak verleen. Artikel 63(1) van die Registrasie van Aktes Wet 47 van 1937 vereis dat 'n beperkte saaklike reg ten aansien van onroerende goedere geregistreer moet word sodra 'n beperkte saaklike reg gevestig word. Indien die serwituut geregistreer word, sal dit afdwingbaar wees teen die eienaar van die dienende erf asook sy regsopvolgers. Indien die genoemde eienaar gemagtig is om die serwituut eensydiglik te verskuif, sal dit inbreuk maak op die eienaar van die heersende erf se beperkte saaklike regte ten aansien van die dienende erf. Die doel van hierdie tesis is om te evalueer tot watter mate howe daartoe in staat is om die gemenereg te verander op grond van billikheid en geregtigheid. Die gevolgtrekking is dat die hof se beleidsargumente oortuigend is aangesien die reg voortdurend moet verander ten einde te voldoen aan die veranderende omstandighede. Die regsvergelykende en historiese gronde vir die hof se gevolgtrekking is egter onoortuigend. Die tesis illustreer dat daar geen historiese gronde bestaan vir die beslissing nie asook dat meer ekstensiewe en kontekstuele regsvergelykende navorsing wel die hof se beslissing staaf. Hierdie tesis evalueer ook die grondwetlike implikasies van die nuwe reël en kom tot die gevolgtrekking dat die toepassing van 'n benadering ingevolge waarvan die eienaar van „n dienende erf gemagtig word om 'n serwituut eensydig te verskuif, nie 'n onteiening of 'n arbitrêre ontneming teweegbring nie op voorwaarde dat die vereistes soos uiteengesit in die uitspraak aan voldoen word en dat die verkryging van 'n hofbevel 'n moontlike voorvereiste is vir die verskuiwing van 'n serwituut.

Street trees are an important component of the urban forest that can provide direct and indirect benefits to social and ecological sustainability in cities. Temporal and spatial interactions between human and non-human management agents determine the distribution and health of street tree populations in urban areas. This dissertation seeks to enhance our understanding of the spatial patterns and processes affecting street trees by investigating the agents and social-ecological determinants of changes to street tree distributions in urban residential neighborhoods. The research was guided by three primary questions: (1) Are recent changes to the spatial distribution of street trees influenced by socio-demographic household and neighborhood characteristics? (2) Which management agents are the strongest predictors of recent changes to street tree distributions and does the contribution of these agents vary in relationship to social-ecological patterns within a city? (3) To what extent are household street tree management decisions related to the built and bioecological material characteristics of the public right-of-way? These questions were investigated in a case study that examined street tree management and public right-of-way (PROW) canopy change associated with single-family residential areas in and near the City of Tampa, Florida. The methodological approach employed a multi-method design using a conceptual framework developed to capture the complexity of management within human ecosystems. Urban remote sensing and spatial analytical techniques were used to examine the geographic association between patterns of street tree change and socio-demographic characteristics. Household survey techniques were utilized to examine the determinants of street tree management; specifically planting, removal, and trimming. Interviews with key informants familiar with urban forest management provided additional insights to complement the location specific knowledge of household survey respondents. Street tree change was examined for the period of 2003 to 2006, and information about household management actions also included recent years (i.e., 2009-2011). A citywide pattern of street tree increases was disproportionately distributed with respect to socioeconomic status; with greater increases in affluent neighborhoods. Patterns of change within local portions of the study area revealed significant and spatially variable relationships with socioeconomic status, as well as race/ethnicity variables and indicators of lifestyle differences. The findings suggest that the citywide pattern of change associated with socioeconomic status may perpetuate an inequitable outcome in the distribution of street trees at the expense of less affluent neighborhoods. The local patterns of change indicate that the processes driving street tree distributions may also reflect differences in attitudes toward trees. The case study did not find sufficient evidence to link the actions of individual agents with street tree change. Street tree increases were more likely in areas where tree trimming had been reported and where property market values were greater, but less likely in PROW segments with overhead power lines. Households, public agencies and builders, but not neighborhoods, were the primary human street tree management agents. Past and ongoing land development and redevelopment decisions, including the configuration of PROW infrastructures, may be one of the most important factors affecting patterns of street tree change. Landscape decisions and practices influenced by household and neighborhood group dynamics also appear to be important factors affecting street tree change. Damages caused by storm event and differences in tree species lifecycle characteristics represent important non-human agents of street tree change. The findings indicated that public agencies are not the only managers of street trees and household tree management does not stop at the boundary of private property. There was no evidence of a relationship between household management actions and the material conditions of the PROW. However, there was a relationship between the presence of either power lines or sidewalks and household survey responses about who should bear responsibility for street tree management and the liability. Household respondents expressed an increased sense of personal responsibility for street tree management when a sidewalk was in front of their home. This dissertation addressed an important gap in understanding about the factors driving street tree change. Planting, removal, and trimming of street trees in Tampa is a shared responsibility with complex spatial patterns and multi-scalar drivers. An important conclusion is that the sustainability of street tree populations within the urban forest will require urban planners and managers to better understand how these management agents cooperate if they are to promote healthy, safe and beneficial street tree populations as a part of the urban forest.

This creative project presents guidelines for Rail to Trail Conversion. A preliminary plan for conversion of the CSX running from Richmond County through Delaware County, and ending in Marion County, Indiana, is presented as a case study. The line, which connects several communities and several points of interest along the railroad right-of-way, has been requested for abandonment.To keep the line for interim public use, one of the possibilities is to convert the line to trail use. The trail corridor might create a good linkage between several adjacent places, because it provides various recreational zones along the former railroad right-ofway. There will be two different kinds of trail corridor-urban and rural trail. The distinction between the two will be one of use, urban trails will be used for daily activities and rural trails usually used primarily during weekends, holidays, and vacation time.The development of trail corridor will also encourage movement of people foreither cycling or walking. Campgrounds, wildlife watching stations, scenic overlook areas, trailheads, and outdoor fitness centers are the most common auxiliary components associated with trail development. Wherever the improvement passes through communities, the communities will benefit from the improvement of retailing activities. Each improvement requires certain criteria of location and land surface.Rail to trail conversion is a costly project. In order to make the project easier and economically feasible, the project should encourage more individuals, private organizations, and public agencies to get involved with the conservation. Local newspapers, broadcast on local radio and television, and interest group workshops are the most effective means of developing support. Time is critical in developing succesful rail to trail conversion. The project should be implemented as soon as the railroad has been abandoned, in order to prevent the tracks reverting to adjacent landowners. / Department of Urban Planning

Among the vibration effects are damage to buildings. In this study, the effects of the vibration produced by suburban trains in buildings was investigated, by taking a railway line with mixed passenger and cargo traffic as a (typical) case study. Measurements were taken, aiming to identify the vibration levels in buildings adjacent to the railway line and which presented visible cracks in their surfaces. The results obtained revealed that vibration levels produced by passenger trains were below the limits which could potentially cause damage. However, simulations performed in order to estimate the vibration levels induced by freight trains evidenced the occurrence of levels greater than those acceptable for the type of buildings investigated. / Atualmente, os centros urbanos estão mais sujeitos à vibração induzida por tráfego, em virtude do aumento do volume deste. Dentre os efeitos da vibração, estão os danos em edificações. Neste estudo, foram investigados os efeitos da vibração produzida pelo tráfego de trens suburbanos em edificações, tomandose como caso (típico) de estudo uma linha férrea com tráfego misto de passageiros e de carga. Medições foram realizadas, visando identificar os níveis de vibração em edificações adjacentes à linha férrea e que apresentavam fissuração visível em suas fachadas. Os resultados obtidos mostraram que os níveis de vibração produzidos pelo tráfego de trens de passageiros apresentaram-se abaixo dos limites que potencialmente causariam dano. Todavia, simulações realizadas para estimar os níveis de vibração induzidos por trens de carga evidenciaram a ocorrência de níveis superiores aos aceitáveis para o tipo de edificações investigadas.

abstract: In the United States, especially in metropolitan areas, transmission infra-structure is congested due to a combination of increasing load demands, declining investment, and aging facilities. It is anticipated that significant investments will be required for new construction and upgrades in order to serve load demands. This thesis explores higher phase order systems, specifically, six-phase, as a means of increasing power transfer capability, and provides a comparison with conventional three-phase double circuit transmission lines. In this thesis, the line parameters, electric and magnetic fields, and right of way are the criteria for comparing six-phase and three-phase double circuit lines. The calculations of the criteria were achieved by a program developed using MATLAB. This thesis also presents fault analysis and recommends suitable pro-tection for six-phase transmission lines. This calculation was performed on 4-bus, 9-bus, and 118-bus systems from Powerworld® sample cases. The simulations were performed using Powerworld® and PSCAD®. Line parameters calculations performed in this thesis show that line imped-ances in six-phase lines have a slight difference, compared to three-phase double circuit line. The shunt capacitance of compacted six phase line is twice of the value in the three-phase double circuit line. As a consequence, the compacted six-phase line provides higher surge impedance loadings. The electric and magnetic fields calculations show that, ground level electric fields of the six-phase lines decline more rapidly as the distance from center of the lines increase. The six-phase lines have a better performance on ground level magnetic field. Based on the electric and magnetic field results, right of way re-quirements for the six-phase lines and three-phase double circuit line were calcu-lated. The calculation results of right of way show that six-phase lines provide higher power transfer capability with a given right of way. Results from transmission line fault analysis, and protection study show that, fault types and protection system in six-phase lines are more complicated, com-pared to three-phase double circuit line. To clarify the concern about six-phase line protection, a six-phase line protection system was designed. Appropriate pro-tection settings were determined for a six-phase line in the 4-bus system. / Dissertation/Thesis / M.S. Electrical Engineering 2012
