Desenvolvimento de um sistema de controle para suspensões ativas de elevadores de alto desempenho / Development of a controller for an active suspension system for high performance elevatorsRivas López, Santiago Miguel January 2007 (has links)
O presente trabalho aborda o desenvolvimento de um algoritmo de controle para um sistema de suspensão ativa para elevadores de alto desempenho. Esses dispositivos são muito usados no caso de suspensões veículos automotivos, mas não tanto em elevadores. Visando compreender os fenômenos envolvidos e executar testes do controle proposto através de simulações, é realizado um estudo da modelagem matemática desse sistema. O elevador estudado é de cabine com duplo andar (double-deck) e será usado em uma guia de 200 [m] de curso em um edifício de aproximadamente 500 [m] de altura. A velocidade de estado estacionário do elevador é 40 km/h. Buscando situar este trabalho no campo de pesquisa proposto, é apresentada uma introdução aos critérios e técnicas de controle linear utilizadas. O desenvolvimento do controlador é baseado no uso de um modelo matemático linear em espaço de estados que representa a dinâmica do sistema em um dos planos ortogonais. A síntese do controlador por realimentação no espaço de estados foi feita usando o método da alocação de pólos, com ajuda do regulador quadrático linear, realimentando os estados com um observador de ordem total. Um modelo computacional foi construído e utilizado para a realização de simulações computacionais com o controlador proposto. Os resultados de simulações do sistema passivo e ativo são apresentados e discutidos. / The present work proposes the development of an algorithm to control active suspension systems for high performance elevators. These devices are used in suspensions for automotive vehicles, but not in such a way in elevators. Aiming at the understanding of the involved phenomena and making tests of the controller considered through simulations, a mathematical model of this system is developed. The studied elevator is a double-deck one and will be used in a 200 [m] guide in an approximately 500 [m] height skyscraper. The steady state speed of the elevator is 40 km/h. Trying to contextualize this work, it is presented an introduction to the criteria and techniques of linear control applied in this work. The development of the controller is based on the use of a linear mathematical model in the states space that represents the dynamics of the system in one of the two orthogonals planes. The synthesis of the feedback controller in the states space was made using the pole placement method with the aid of the linear quadratic regulator, and the feedback of the states with a full order observer. A computational model was constructed. The results of passive and active simulations of the system are presented and discussed.

O pólo Manaus e o desequilíbrio intra-regional na Amazônia ocidental : o caso de RoraimaCruz, Getúlio Alberto de Souza January 2009 (has links)
Esta dissertação tem por objetivo investigar os fatores condicionantes do processo de desenvolvimento de Roraima. Transformado de Território Federal em Estado membro da federação brasileira pela Constituição de 1988, Roraima está num ponto de inflexão de sua história, e especialmente do modelo de economia que deu base à sobrevivência de sua população até agora. A conhecida, localmente, economia do contracheque “chapa branca” deu bons resultados até o início dos anos 90 da década passada. De lá para cá demonstra claros sinais de exaustão, afinal, o estado está perdendo posição relativa no ranking brasileiro. Isso pode ser medido tanto pelo indicador de produção material, o PIB per capita quanto pelo IDH-M, adotado mundialmente como melhor medidor do nível de desenvolvimento de uma população. Assim, o estado de Roraima tem de enfrentar o desafio de mudar o modelo econômico que lhe deu até aqui sustentação, e isso terá de ocorrer sob um cenário de restrição ao uso de seu capital natural imposto pelo Estado nacional, e a partir dos liames econômicos que ligam o Pólo Secundário Roraima ao Pólo Econômico Manaus. Isso condiciona o desenvolvimento do primeiro em relação ao segundo. Do ponto de vista do desenvolvimento sub-regional, Roraima vem crescendo num ritmo mais lento que os demais estados da Amazônia Ocidental. O desempenho do Produto Interno Bruto per capita e o Índice de Desenvolvimento Humano Municipal (IDH-M), medido entre os anos de 1991 (ano de implantação do estado) e 2005 (dados obtidos junto ao IBGE/PNDU), além dos dois condicionantes já referidos, indicam que a indução de qualquer processo de mudança em Roraima, passa necessariamente pela intervenção do estado local, que não dispõe de recursos orçamentários para fazê-lo, e não detém o controle das políticas mineral, ambiental, indígena, fundiária e creditícia, todas enfeixadas nas mãos do Estado nacional. Em conclusão, qualquer possibilidade de desenvolvimento de Roraima, passa pela negociação de um pacto republicano com o Estado nacional. / This dissertation aims to investigate the conditioning factors of the development process of Roraima. Changed from Federal Territory in the State member of the Brazilian federation by the Constitution of 1988, Roraima is in a point of inflection of its history, and especially the model of economy which was based on the survival of its people so far. The known, locally, the economy "white hat" proof of income has yielded good results until the early 90s of the last decade. From then until now shows clear signs of exhaustion, after all, the state is losing relative position in the Brazilian ranking. This can be measured both by the indicator of material production, GDP per capita as the HDI-M, used worldwide as a better gauge the level of development of a population. Thus, the state of Roraima has to face the challenge of changing the economic model which has hitherto support, and this must occur under a scenario of restricting the use of its natural capital tax by the national State, and from economic links that linking the Secondary Pole at Roraima to Economic Pole at Manaus. It influences the development of the first in the second one. From a sub-regional development point of view, Roraima is growing in a slower pace than the other states of the Western Amazon. The performance of the Gross Domestic Product per capita and the Municipal Human Development Index (IDH_M), measured between the years 1991 (year of implementation of the state) and 2005 (data obtained from the IBGE / PNDU), besides the above two conditions, the induction of any process of change in Roraima, inevitably by the intervention of the state site, which has no budgetary resources to do so and has no control of the mineral, environmental, indigenous, land and credit policies. Each bottle in the hands of the national state. In conclusion, any possibility of development in Roraima is to negotiate a pact with the Republican National State.

Contribuição do SISCOM na investigação do blurring do polo temporal associado à atrofia hipocampal em pacientes com epilepsia do lobo temporal: um estudo com SPECT cerebral / Contribution of SISCOM in the investigation of temporal pole blurring in patients with temporal lobe rpilepsy and hippocampal atrophy: a brain SPECT studyDaniele Kanashiro Sonvenso 04 March 2016 (has links)
Este foi um estudo retrospectivo de 18 pacientes com atrofia hipocampal (AH) e 21 pacientes com AH associada ao blurring do polo temporal (BPT), nos quais realizamos a investigação das alterações perfusionais ao SPECT (Single Photon Emission Computed Tomography) crítico, ao SPECT intercrítico e ao SISCOM (Subtraction Ictal SPECT Coregistered to MRI) e sua comparação com os dados de avaliação pré-cirúrgica. Os pacientes com BPT apresentaram início mais precoce da epilepsia, uma duração de epilepsia maior e um período maior de seguimento pós-operatório (PO). O padrão pefusional ipsilateral ao SPECT crítico, o qual denominamos de padrão -típico?, foi o padrão perfusional mais frequentemente encontrado em ambos os grupos de pacientes com e sem BPT. Ao SPECT intercrítico, a maioria dos pacientes com BPT apresentaram hipoperfusão ipsilateral no lobo temporal (LT) epileptogênico, enquanto que no grupo sem BPT esta hipoperfusão foi observada em metade dos pacientes. Ao SISCOM, o padrão perfusional -típico? foi novamente o mais encontrado em ambos os grupos com e sem BPT. Entretanto, os padrões considerados -atípicos? foram encontrados mais frequentemente nos pacientes com BPT, o que nos sugere um padrão de propagação das crises epilépticas discretamente diferente neste grupo com BPT, o qual envolve outras áreas dos LT bilateralmente. Contrariamente à nossa hipótese inicial, não encontramos associação entre a presença de BPT e a presença de hiperperfusão no polo temporal (PoT) seja ao SPECT crítico ou ao SISCOM. Por este achado, nossos dados não suportam a idéia de que o BPT seja resultado de alterações teciduais intercríticas secundárias a um maior envolvimento ou participação deste polo na geração ou propagação de crises epilépticas na epilepsia do lobo temporal (ELT) mesial. Por outro lado, nossos resultados sugerem que o PoT é uma região frequentemente envolvida pelas crises do LT. Particularmente, a hiperperfusão no PoT ipsilateral à AH ao SISCOM foi mais encontrada nos pacientes com casos clínicos típicos de ELT mesial, sugerindo que o PoT é mais frequentemente envolvido (um padrão típico) em crises epilépticas em casos clínicos com informações mais concordantes (clear cut) e sugestivas de ELT mesial unilateral / This was a retrospective study of 18 patients with hippocampal atrophy (HA) and 21 patients with HA associated to temporopolar blurring (TPB). We performed an investigation of perfusion changes of ictal single photon emission computed tomography (SPECT), interictal SPECT and subtraction ictal SPECT coregistered to magnetic resonance imaging (SISCOM) and its comparison with results of presurgical evaluation. Patients with TPB showed earlier epilepsy onset, longer duration of epilepsy and a longer period of post surgical follow-up. The ipsilateral perfusion pattern in the ictal SPECT, which we denominated -typical? pattern, was the most frequent in both groups of patients, with and wihout TPB. In the interictal SPECT, most of patients with TPB showed ipsilateral hypoperfusion to the epileptogenic temporal pole (TP), while in the group without TPB this hypoperfusion was observed in half of the patients. Through SISCOM, the typical perfusion pattern was the most frequent in both groups. However, the patterns considered -atypical? were found more frequently in patients with TPB, which suggests a pattern of propagation of epileptic seizures slightly different in the group with TPB, which involves other areas of TL bilaterally. Adversely to our hypothesis, we did not found association between the occurrence of TPB and the hyperperfusion in the TP neither in the ictal SPECT nor SISCOM. Based on this finding, our data does not support the idea that the BTP is a result of interictal secondary tissue changes due to a higher involvement or role of this pole in the generation or propagation of epileptic seizures in the mesial temporal lobe epilepsy (TLE). On the other hand, our results suggest that the TP is a region frequently involved by seizures of TL. Particularly, the hyperperfusion in the TP which is ipsilateral to the HA through SISCOM was the most found in patients with typical clinical cases of mesial TLE, suggesting that the TP is frequently involved (a typical pattern) in epileptic seizures of clinical cases with more concordant information (clearcut) and suggestive of unilateral mesial TLE
