Diploma thesis deals with the design of the automatically controlled ramp for the boarding of physically disabled people in city buses. The initial research section deals with the regulations and directives that must be respected in the design, the issue of wheelchair mobility and the analysis of design considered elements. In the second part the thesis goes to the chosen design solution. The design input parameters are the height of the ramp cassette, the slope of the ramp when boarding and the width of the boarding platform. The platform is extended by a pair of pneumatic cylinders along with a scissor mechanism guided in a linear ball guide. The boarding platform is made of an aluminium honeycomb panel which strength is verified by analytical calculation. At the front edge, the boarding platform is equipped with a pressure-sensitive edge The ramp cassette is made up of a welded frame of steel profiles and subjected to stress strain analysis. The thesis is accompanied by complete drawing documentation.

Methods: nine middle-aged man (56,77 ± 2,81 years), active, with arterial hypertension, no medication, subject a baseline to control for evaluate the arterial blood pressure profile, was done three times a week during two weeks, in supine, seated and stand up position. Systolic blood pressure (SBP) was recorded in the appearing as the first sound (first-phase Korotkoff), and diastolic blood pressure (DBP), as the fifth sound (fifth-phase Korotkoff). All subjects were submit a performed ramp continuous dynamic physical exercise test (RCDPET), in electromagnetic cycloergometer (Corival 400) in 4 W during 4 minutes, follow up increment of 15 or 20 W/min, until exhaustion and/or sign limit. Heart rate was collected in real time, on a beat-to-beat basis (electrocardiogram ECAFIX TC500), during all RCDPET, vastus lateralis SEMG activity was collected continuous (Lynx Tecnology Eletronic Ltd) and the ventilatory and metabolic variables VO2 e VCO2 were also collected breath-bybreath quantification of ventilatory volumes and gas exchanges (CPX/D MedGraphics). Workload, heart rate (HR), VO2, VCO2 and surface electromyography (SEMG) analysis by 5 different methods: ventilatory visual graphic method (VVM) used with gold standard, linear-linear bissegmentar mathematical model method (LLMM) applied to carbon dioxide output data and Hinkley mathematical model method applied to heart rate data (HMM-HR), VCO2 data (HMMVCO2) and RMS index of SEMG activity data (HMM-RMS), who appoint exercise level in was to detect the AT. Workload, heart rate (HR), VO2, VCO2 and surface electromyography (SEMG) were statistical analysis to non-parametric tests were selected: Friedman test for repeated measures followed by post-hoc Dunn test for multiple comparisons and Spearman correlation test was also used. Significance level was set at 5%. Results: HMM-VCO2 model present significant difference (p<0,05) when compare with four methods (MVV, MMLL, HMM-FC and HMM-RMS) for values of workload. For values of VCO2 and heart rate, HMM-VCO2 model present significant differed (p<0,05) when compare with HMM-FC and HMM-RMS models; for values of VO2, HMM-VCO2 model present significant difference (p<0,05) when compare with MMLL, HMM-FC and HMM-RMS models. The HMM-VCO2 model present for all variables minor values in relation the MVV, MMLL, HMM-FC and HMM-RMS models. It was observed no significant correlations (p>0,05) when VVM (gold standard) model was correlation with LLMM (rs=0,56), HMM-HR (rs=0,40), HMM-VCO2 (rs=0,43) and HMM- RMS (rs=0,40) in AT power output values detected by the gold standard. However, it was observed significant correlations (p<0,05) in the correlation workload and VO2 (rs=0,75), and workload and HR (rs=0,69) values when utilize VVM (gold standard) model. Conclusions: the results found in the present investigation suggest that the mathematical models were effective in detecting the response pattern changes in variables (HR, VO2, VCO2 e RMS index of SEMG activity) detecting adequately the AT and the date of workload, heart rate 30 (HR), VO2, VCO2 and surface electromyographic (SEMG) analyze the HMM-VCO2 model present for all variables minor values, and this fact can be associated to hypertensive subjects have a increases in the sympathetic nervous system outflow and than might contribute to prevalence of anaerobic metabolism in the energetic production and this fact can be associated with different skeletal muscle fiber composition, with relative preponderance of glycolytic fast-twitch (type II-b) over oxidative fast-twitch (type II-a) or slow-twitch (type I) and than might contribute to impaired aerobic metabolism. The methodological limitation in this study in no carry out the biopsy to muscle, propose the continuation this topic in this study. / Objetivo:Determinar e correlacionar o limiar de anaerobiose a partir da resposta da freqüência cardíaca, do sinal eletromiográfico e das variáveis ventilatórias e metabólicas, utilizando metodologias matemáticas e compará-las com o método da análise visual gráfica das variáveis ventilatórias, para estimar a capacidade aeróbia em homens hipertensos de meia-idade. Metodologia: 9 homens de meia-idade (56,77 ± 2,81 anos), ativos ocupacionais, com hipertensão arterial, sem uso de medicamentos, submetidos a um período controle para o perfil da pressão arterial sistólica (PAS) e diastólica (PAD) de duas semanas com 3 medições semanais, nas posições supina, sentada e em pé. Os valores de PAS foram determinados no momento do aparecimento do primeiro som (fase I de Korotkoff) e os valores de PAD no desaparecimento do som (fase V de Korotkoff). Os mesmos, foram submetidos a um protocolo de teste de exercício físico dinâmico contínuo do tipo rampa (TEFDCR), realizado em cicloergômetro eletromagnético (Corival 400), com carga de 4 Watts (W) durante 4 minutos seguido de um incremento de potência de 15 ou 20 W/min, até a exaustão física e/ou sintoma limitado. Durante todo o TEFDC-R, a FC foi captada por meio de um monitor cardíaco (ECAFIX TC500), batimento a batimento em tempo real, o sinal eletromiográfico do músculo vasto lateral, foi coletado continuamente(Lynx Tecnologia Eletrônica Ltda), e as variáveis ventilatórias e metabólicas VO2 e VCO2 foram também coletadas respiração a respiração (ergoespirômetro CPX/D da marca MedGraphics). Os dados de potência, VO2, VCO2, FC e RMS do sinal da EMGs foram analisados por 05 diferentes metodologias que são: método do modelo visual gráfico ventilatório (MVV), o qual foi utilizado como padrão de referência, método do modelo matemático bissegmentado linear-linear (MMLL) aplicado aos dados de produção de gás carbônico (VCO2) e método do modelo matemático de Hinkley aplicado aos dados de FC (MMH-FC), VCO2 (MMH-VCO2) e RMS do sinal da EMGs (MMH-RMS), que indicaram o nível de exercício em que foi determinado o LA. Os valores de potência, VO2 , VCO2 , FC e RMS do sinal da EMGs foram analisados a partir dos testes estatísticos não paramétricos de Friedman para medidas repetidas seguido de técnica de comparação múltipla (post-hoc de Dunn) e teste de correlação de Spearman com nível de significância de &#945; = 5%. Resultados: para os valores de potência, o modelo MMH-VCO2 apresentou diferença estatisticamente significante (p<0,05) quando comparado com os 4 outros modelos de análise (MVV, MMLL, MMH-FC e MMHRMS). Houve diferença estatisticamente significante (p<0,05) para os valores de VCO2 e FC, entre o modelo MMH-VCO2 em relação aos modelos MMH-FC e MMHRMS; para o VO2 entre o modelo MMH-VCO2 em relação aos modelos MMLL, MMH-FC e MMH-RMS. O modelo MMH-VCO2 apresentou para todas as variáveis estudadas valores menores em relação aos valores determinados pelas outras metodologias. Não houve associação significativa (p<0,05) entre o modelo MVV e os modelos MMLL (rs=0,56), MMH-FC (rs=0,40), MMH-VCO2 (rs=0,43) e MMH-RMS (rs=0,40) para os valores de potência, analisados no nível em que foi determinado o LA. Porém, houve associação significativa entre potência e VO2 (rs=0,75) e entre potência e FC (rs=0,69) utilizando-se o modelo MVV considerado no presente estudo como padrão de referência. Conclusões: os resultados obtidos no presente estudo, 28 sugerem que os modelos matemáticos de análise mostraram-se sensíveis na determinação da mudança de padrão das respostas das variáveis estudadas (FC, VO2, VCO2 e RMS do sinal eletromiográfico), determinando adequadamente o limiar de anaerobiose, e que o modelo matemático de Hinkley aplicado aos dados de VCO2 apresentou-se sempre com menores valores, o que pode estar relacionado ao fato dos voluntários hipertensos estudados apresentarem aumento de atividade do sistema nervoso simpático, e isto pode contribuir para a predominância do metabolismo anaeróbio na produção de energia, que poderia estar relacionado com a composição das fibras musculo-esqueléticas, com predomínio de fibras de contração rápida glicolítica (tipo II-b) em relação a de contração rápida oxidativa(tipo II-a) e de contração lenta (tipo I) podendo resultar em prejuízo do metabolismo aeróbio. Devido a limitação metodológica da não realização de biópsia muscular no presente estudo, sugere-se a continuidade deste trabalho com o referido enfoque.

The mapping and interpretation of 3D seismic reflection data of Baixa Grande Fault, SW portion of Umbuzeiro Graben, points as responsible for basin architecture configuration an extensional deformational process. The fault geometry is the most important deformation boundary condition of the rift stata. The development of flat-ramp geometries is responsible for the formation of important extensional anticline folds, many of then hydrocarbon traps in this basin segment. The dominant extensional deformation in the studied area, marked by the development of normal faults developments, associated with structures indicative of obliquity suggests variations on the former regime of Potiguar Basin through a multiphase process. The changes in structural trend permits the generation of local transpression and transtension zones, which results in a complex deformation pattern displayed by the Potiguar basin sin-rift strata. Sismostratigraphic and log analysis show that the Baixa Grande Fault acts as listric growing fault at the sedimentation onset. The generation of a relay ramp between Baixa Grande Fault and Carnaubais Fault was probably responsible for the balance between subsidence and sedimentary influx taxes, inhibiting its growing behaviour. The sismosequences analysis s indicates that the extensional folds generation its diachronic, and then the folds can be both syn- and post-depositional / Apesar do significativo estudo e explora??o da Bacia Potiguar, extremo-leste da margem equatorial brasileira, pela ind?stria do petr?leo, a bacia ainda permite uma interessante discuss?o acerca de sua origem e dos mecanismos de trapeamento de hidrocarbonetos associados. O mapeamento e interpreta??o de dados de s?smica de reflex?o 3D da Falha de Baixa Grande, por??o SW do Graben de Umbuzeiro, aponta como respons?vel pela defini??o da arquitetura desta por??o da bacia um processo deformacional, essencialmente, distensional. A geometria da Falha de Baixa Grande ? a principal condi??o de contorno da deforma??o dos estratos sedimentares da fase sin-rifte da bacia. O desenvolvimento de geometrias do tipo flat-ramp ? respons?vel pela forma??o de importantes dobramentos distensionais anticlinais, muitos deles portadores de hidrocarbonetos neste segmento da bacia. A predominante deforma??o distensional na ?rea de estudo, marcada pelo desenvolvimento de falhas normais, associada a estruturas indicativas de obliq?idade, sugere varia??es no regime distensional formador da bacia Potiguar atrav?s de processos multif?sicos. A varia??o no trend estrutural ao longo da evolu??o da bacia permite a gera??o de zonas de comportamento local transtrativo e transpressivo, resultando no desenvolvimento do complexo padr?o deformacional impresso nos estratos da fase sin-rifte da Bacia Potiguar. An?lises sismoestratigr?ficas e de dados de po?os indicam que a Falha de Baixa Grande atuou como falha l?strica de crescimento nos primeiros epis?dios de sedimenta??o da bacia. A cria??o de uma rampa de revezamento entre as Falhas de Baixa Grande e Carnaubais foi, provavelmente, respons?vel pelo equil?brio entre as taxas de subsid?ncia e aporte sedimentar inibindo o funcionamento da falha como falha de crescimento. A an?lise de sismoseq??ncias permite, por fim, concluir que a gera??o dos dobramentos distensionais ? di?crona, podendo estes ser sin a p?s-deposicionais

[pt] Em obras ambientais, onde geossintéticos são utilizados como sistema de proteção e de cobertura de taludes, é de extrema importância o conhecimento do mecanismo de interação solo-geossintético, através da obtenção dos parâmetros de resistência da interface (adesão e ângulo de atrito da interface). O ensaio de laboratório mais adequado para a obtenção desses parâmetros, nestas condições, é o de cisalhamento em plano inclinado ou ensaio de rampa, pois permite simular a condição de campo onde o cisalhamento ocorre em um plano inclinado sob baixas tensões. Assim, este trabalho apresenta um estudo sobre a interação sologeossintético através de ensaios de rampa, executados em um equipamento de grandes dimensões, visando analisar a influência de alguns fatores, tais como, tipo de geossintético, tipo de solo, densidade relativa do solo e tensão confinante. Foram utilizados dois tipos de geossintéticos, uma geomembrana de PVC e uma geogrelha uniaxial e dois tipos de solo, areia e pedregulho (brita). A análise da influência da densidade relativa do solo foi realizada através de ensaios na interface areia-geossintético em duas densidades relativas diferentes (35 e 100%). A influência da tensão confinante foi estudada através de ensaios com três tensões confinantes distintas (2,1; 3,2 e 5,1 kPa). Os resultados mostram que a influência de fatores como densidade relativa do solo, tensão confinante e tipo de solo, dependem do tipo do geossintético. O aumento da densidade relativa do solo promove um acréscimo de resistência na interface para a geogrelha e uma redução para a geomembrana. O aumento da tensão confinante reduz o ângulo de rampa na ruptura, sendo este efeito mais pronunciado na interface areia-geogrelha. Em relação ao tipo de material, a interface brita-geogrelha é a que apresenta maior resistência. / [en] In environmental works, where geosynthetics are used as protection system and of slope covering, it is of extreme importance the knowledge of the interaction mechanism soil-geosynthetic, through the obtaining of the parameters of resistance of the interface (adhesion and interface friction angle). The laboratory test more appropriate for the obtaining of those parameters, in these conditions, is it the inclined plane test or ramp test, because it allows to simulate the field condition where the shearing happens in inclined plane under low tensions. Like this, this work presents a study about the interaction soilgeosynthetic through ramp tests, executed in an equipment of great dimensions seeking to analyze the influence of some factors, such as, geosynthetic type, soil type, relative density of the soil and confinement pressure. Two geosynthetics types, a PVC geomembrane and a uniaxial geogrid, two soil types, it sand and gravel (break). The analysis of the influence of the relative density of the soil was accomplished through tests in the interface sand- geosynthetic in two different relative densities (35 and 100%). The influence of the confinement pressure was studied through tests with three different confinement pressures (2,1; 3,2 and 5,1 kPa). The results show that the influence of factors as relative density of the soil, pressure confinement and soil type, they depend on the type of the geosynthetic. The increase of the relative density of the soil promotes an increment in the interface resistance for the geogrid and a reduction for the geomembrana. The increase of the confinement pressure reduces the ramp angle in the rupture, being this more pronounced effect in the interface sand-geogrid. In relation to the material type, the interface gravel-geogrid presents larger resistance.

The subject matter of the assigned project is Aquapark Brno – located near Lužánky. The subject is an architectural study elaboration of an aquapark adjoining the current swimming pool building which was established in 1979. This building facility is used primarily by professional swimmers and sportsmen for it contains the only 50 meters long swimming pool with a tribune in Brno. The aim of the project is to create new areas and pools for visitors with recreational intentions and therefore to widen the possibilities for free time activities. The project also deals with restoration of a 16 meters long training pool in the existing building, creation of inner and outer aquapark areas and adding exercise and dance halls as an extension to the existing fitness center. Another goal of this project was to make the pedestrian access to the area more pleasant which is achieved by creating an underground parking space in the area of the existing building’s frontal space and also by designing a footpath leading from the remote side of the excessively frequented Sportovní street. The primary aim of the project is an operational connection of the existing and the new building by a central building and also preventing an eclipse of the area by integrating the building in the area’s hillside. The advantage of the project is the presence of relaxation facilities and sports areas. The project completes the sporting environment of the area which makes it an attractive locality for a family recreation.
