Este trabalho teve como objetivo analisar a demanda potencial para um sistema de compartilhamento de bicicletas pedelecs no campus da USP de São Carlos, com foco nos deslocamentos de estudantes entre as duas áreas do campus. Para tanto, foi elaborado um conjunto de procedimentos, que constituem duas etapas: caracterização do público-alvo e análise da demanda potencial pelas bicicletas pedelecs compartilhadas. Na primeira etapa foi aplicado um questionário, elaborado com a técnica de preferência declarada, para verificar as preferências dos usuários em relação às pedelecs compartilhadas e ao ônibus operado pela USP. Os resultados desta consulta, que envolveu variáveis de condições meteorológicas, situação de ciclovias/ciclofaixas entre as áreas do campus e lotação do ponto de ônibus USP, foram posteriormente utilizados para calibrar um modelo logit e treinar uma Rede Neural Artificial (RNA). Na segunda etapa foi elaborada uma planilha eletrônica com os dados obtidos na coleta, a fim de analisar as probabilidades de escolha da pedelec (ao invés do ônibus USP). Nesta planilha também foram utilizados dados do histórico meteorológico de São Carlos no período entre 2011 e 2015. Alguns dos resultados obtidos são destacados na sequência. A probabilidade de escolha das pedelecs é, em média, três vezes maior quando existem ciclovias/ciclofaixas (em relação à ausência da referida infraestrutura cicloviária). A ocupação do ponto de ônibus USP também é impactante, pois as probabilidades de uso da bicicleta pedelec praticamente dobram quando o ponto está cheio. No caso da meteorologia, foi constatado que as maiores probabilidades ocorrem no Outono e no Inverno, ou seja, nas épocas em que se concentram os dias mais secos e com menores temperaturas. Para o período letivo de 2011 a 2015, considerando a situação atual (isto é, sem ciclovias/ciclofaixas entre as áreas), os valores de probabilidade de uso da pedelec correspondem a 9% com o ponto vazio e 19% com o ponto cheio. Se houvesse ciclovias/ciclofaixas, a probabilidade seria de até 54%. Desse modo, a estratégia de análise desenvolvida conceitualmente, bem como implantada em planilha eletrônica, se constitui em importante ferramenta de auxílio para a condução da política de transportes que a Prefeitura do campus irá adotar para os anos futuros. Além disso, evidencia uma possível demanda potencial para um sistema com pedelecs compartilhadas. / The objective of this study was to analyze the potential demand for a pedelec sharing system at the São Carlos campus of the University of São Paulo (USP), aiming at the displacements of students between the two campus Areas. The set of procedures developed to reach the objective has involved two steps: characterization of the target audience and analysis of the potential demand for shared pedelecs. The first step was accomplished with a questionnaire designed with a stated preference approach for identifying users\' preferences regarding shared pedelecs and the bus system operated by the university. The survey results, which involved variables of weather conditions, existence of bike paths/bike lanes between the campus Areas, and occupancy rates at the USP bus stop, were subsequently used to calibrate a logit model and to develop an Artificial Neural Network (ANN). The survey data were also used in the second step of the process, in which an electronic spreadsheet was created to analyze the probabilities of choosing the pedelec alternative (instead of the bus route operated by university). The spreadsheet was also fed with meteorological data of São Carlos in the period between 2011 and 2015. Some of the obtained outcomes are highlighted in the sequence. The probability of a pedelec being chosen is almost three times higher if bike paths/bike lanes do exist than if they do not exist. The occupancy rates of the bus stop are also particularly relevant. The probability of someone choosing a pedelec nearly doubles when the bus stop is crowded. Regarding the weather conditions, the highest probabilities are observed in the Fall and Winter seasons, i. e. in the driest and coldest days. For the entire academic period comprised between 2011 and 2015, the probabilities range from 9% (empty bus stop) to 19% (full bus stop), considering the current situation (i. e. no cycleways connect the two campus Areas). In the presence of this cycling infrastructure, however, the probability goes up to 54%. Thus, the strategy of analysis conceptually developed, and made available through an electronic spreadsheet, may be an important support tool for the implementation of transport policies by the campus administration. In addition, it highlights a likely potential demand for a system of shared pedelecs.

O fenômeno do recente crescimento do uso da bicicleta no Município de São Paulo, cidade não propriamente amigável à sua utilização, merece uma reflexão cuidadosa, baseada na análise detalhada dos motivos que realmente induziram esta situação. É importante que a avaliação destes fatos não induza a crer que sejam seus únicos e principais motivos o atual momento de consciência sobre a necessidade de preservação do meio ambiente e a valorização de políticas que envolvam o conceito de independência de utilização de recursos naturais. No caso paulistano, a bicicleta tem sido uma saída espontânea encontrada por um setor específico da população, como tentativa de contornar a crônica má qualidade presente na mobilidade cotidiana da cidade, decorrência direta da deficiência dos serviços de transporte público existentes. Pode-se afirmar que a constatação do aumento de uso da bicicleta em São Paulo tem sensibilizado o poder público e a sociedade, induzindo à realização de ações para seu estímulo e consolidação. Assim estão em alta como políticas públicas de transporte sustentando sua viabilidade, experiências consolidadas e bem sucedidas de muitas metrópoles no mundo, onde já se afirmou como uma boa opção de mobilidade. Entretanto esta visão poderia se tornar equivocada e comprometer o atendimento ao que é realmente necessário para uma metrópole como São Paulo, se não for precedida ou acoplada à reestruturação de todo o sistema de transportes públicos paulistanos, de forma a promover o salto de qualidade e de eficiência exigidos. Neste processo o papel da mobilidade cicloviária é muito importante e poderá ser consolidado como elemento agregador desde que respeitadas e bem exploradas suas características. / The phenomenon of the recent growth on the bicycle usage in the city of São Paulo, which actually is not friendly to its use, deserves a thorough reflection, based on the detailed analysis of the reasons which induced such situation. It is important that the evaluation of these facts do not lead us to believe that the only and main reasons are the current scenario of the consciousness on the environment preservation and appreciation of policies which involve the concept of independence of natural resources usage. As for São Paulo case, the bicycle has been a spontaneous solution found by a specific population sector, as an attempt to get around the chronic low quality existing in the city´s daily mobility, direct outcome of the deficiency in the current public transport services. This deficiency is the result of successive and misguided policies of mobility. It is possible to claim that the increase in the bicycle use in São Paulo has sensitized the public power and the society inducing to the completion of actions in order to stimulate and consolidate it. Therefore these actions are now the spotlight among the public policies of transport, supporting its viability from consolidated and successful experiences in many metropolis of the world, where the bicycle use has already been identified as a good mobility option. However this view could become misguided, compromising the commitment to what is really necessary to a city like Sao Paulo, if it is not preceded or coupled to the restructuring of the whole Sao Paulo public transport system, in order to trigger the required quality and efficiency improvement. In this proccess the role of the bicycle mobility is very important and may be consolidated as the gathering element, taking into consideration that its characteristics are respected and well explored.

The purpose of this prospective, randomized, controlled clinical investigation is to evaluate the performance of the Motorized Ridge Expanders (MRE), and to compare its results with the ones achieved utilizing lateral ridge augmentation (LRA). Eight subjects with bilateral ridge deformities were selected. One technique was used on the right site and the other on the left site. Implants were placed six months after the bone augmentation procedures. All the measurements were recorded at 2 and 5 mm from the most coronal part of the crest. The augmentation achieved with both techniques was statistically significant, 1.2 mm in the LRA, 1.5 mm in MRE at 2 mm from the crest; 1.5 mm and 1.6 mm respectively at 5mm from the crest. The differences between the two techniques were statistically insignificant. The amount of expansion achieved in the MRE site appears to be negatively correlated (P-Value <0.05) with the thickness of the cancellous bone, and it is not affected by the thickness of the cortical plate. The MRE technique appears to be as effective as the LRA technique in augmenting the thickness of atrophic ridges. The defect treated with the MRE showed less bone width contraction during the first 6 months of healing. Histologically, the regenerated bone was vital, trabecular in nature and in direct contact with bone graft particles. / El propósito de esta investigación clínica prospectiva y aleatoria es comparar el aumento horizontal de la cresta alveolar obtenido con el uso de los expansores motorizados de cresta (EMC) y con regeneración ósea guiada (ROG). Fueron selecccionados ocho pacientes con deformidades horizontales del reborde alveolar bilaterales que iban a recibir implantes dentales. Una técnica de regeneración se utilizó en el lado derecho y la otra en el lado izquierdo, para un total de 23 muestras, 13 en el lado experimental (EMC) y 10 en el lado control (ROG). Los implantes fueron colocados seis meses después de los procedimientos de aumento óseo, y se obtuvo una muestra de hueso para estudio histológico. Todas las mediciones clínicas se registraron a los 2 y 5 mm de la parte más coronal de la cresta. El aumento logrado con ambas técnicas fue estadísticamente significativo, de 1,2 mm en la ROG y 1,5 mm con los EMC a 2 mm de la cresta; y 1,5 mm y 1,6 mm, respectivamente, a 5mm de la cresta. Las diferencias entre las dos técnicas no fueron estadísticamente significativas. La cantidad de expansión lograda en el sitio de los EMC parece tener una correlación negativa (p <0,05) con el grosor del hueso esponjoso, y no se ve afectada por el grosor de la cortical. Histológicamente se observó osteoconductividad del injerto óseo y más partículas residuales del mismo en el lado experimental. La técnica de los EMC parece ser tan eficaz como la técnica de ROG en el aumento de la anchura de las crestas atróficas. Los defectos tratados con los EMC mostraron una menor contracción del injerto óseo durante los 6 meses de cicatrización. / El propòsit d'aquesta recerca clínica prospectiva i aleatòria és comparar l'augment horitzontal de la cresta alveolar obtingut amb l'ús dels expansors motoritzats de cresta (EMC) i amb regeneració òssiaguiada (ROG). Es van selecccionar vuit pacients amb deformitats horitzontals bilaterals de la cresta alveolar on es col.locaren implants dentals. Una tècnica de regeneració es va emprar en el costat dret i l'altra a la banda esquerra, per a un total de 23 mostres, 13 al costat experimental (EMC) i 10 en el costat control (ROG). Els implants van ser col.locats sis mesos després dels procediments d'augment ossi, i es va obtenir una mostra d'os per estudi histològic.Totes les mesures clíniques es van registrar als 2 i 5 mm de la part més coronal de la cresta. L'augment aconseguit amb ambdues tècniques va ser estadísticament significatiu, de 1,2 mm a la ROG i 1,5 mm amb els EMC a 2 mm de la carena, i 1,5 mm i 1,6 mm, respectivament, a 5mm de la cresta. Les diferències entre les duestècniques no van ser estadísticament significatives. La quantitat d'expansió aconseguida en el lloc dels EMC sembla tenir una correlació negativa (p<0,05) amb el gruix de l'os esponjós, i no es veu afectada per el gruix de la cortical. Histològicament es observar osteoconductividad l'empelt ossi i més partícules residuals d'aquest en el costat experimental. La tècnica dels EMC sembla ser tan eficaç com la tècnica de ROG en l'augment de l'amplada de les crestes atròfiques. Els defectes tractats amb els EMC mostrar una menor contracció de l'empelt ossi durant els 6 mesos de cicatrització.

There are two transport systems used by agricultural businesses engaged in primary production. These are transport systems involving tractors and motorized vehicles. Transport systems involving tractors are made up of motorized vehicles and vehicles that are Toled Grand Super , or more specifically, a motor vehicle plus one or more vehicles that are towed along. A motorized vehicle refers to an agricultural traktor John Deere 6620. Motorized transport systems are comprised of Lorries Tatra 815 Agro. A lorry can only have one additional vehicle connected to itself. The transport systems mentioned above can be used in agricultural businesses engaged in primary production along with similar or identical productions. Motorized transport systems used in agricultural primary production are in the majority of cases applied to additional productions. This is the given transport system framework, which can be setup with adaptations for various uses. It therefore follows that the possibilities of comparing transport systems using universal undercarriages are increased. Expenditure associated with these transport systems, are easily compared. It is also possible to easily compare transport systems involving tractors with motorized transport systems as long as there is no need for more vehicles connected to them. It is obvious that the use of motorized transport systems for longer distances is preferable to transport systems involving tractors. Expenses for every driven kilometre with the comparable transport systems show a significant difference in cost. This difference is 36,85 Kč. On the other hand, it is preferable to use tractors for shorter distances involving a larger amount of material. he cost of one tonne of material transported is different about 11,55 Kč.

The dissertation deals with non-motorized transport. Specifically, it focuses directly on the new non-motorized traffic sector, which is the riders of roller skates. Title of the dissertation The rules for designing roads for skaters were selected from the point of view of unresolved issues. The main goal of the dissertation is to enable the legislative inclusion of skaters as a separate group into the transport hierarchy so that they can gain space for their movement in the transport area. The result should be primarily a reduction in accidents and an increase in road safety for non-motorized vehicles. Other objectives of the thesis include the creation of design parameter tables for methodological instructions based on the analysis of the data obtained by measuring and determining the critical traffic intensity on existing roads. The dissertation summarizes the current issue of non-motorized transport, but especially the issue of skaters transport. It assesses the situation in the Czech Republic compared to the conditions abroad. It explains the physical patterns of the skater's movements, based on which the spatial demands on the used transport space are derived. The following is an overview of selected methods dealing with measurement and evaluation of transport speeds and intensities. Depending on the values found, rules are then created for designing the basic parameters of the skateboard trail network, which includes, for example, traffic sign design and construction requirements.

This diploma thesis deals with a problem of spores venturia inaequlis recognition. These spores are captured on a special tape which is then analyzed using a microscope. The tape can be analyzed by a laboratorian or by the program Sporedetect v3. This program provides functions for complete picture processing and object recognition. In this diploma thesis, there are also described ways to automatically control a sliding stage of a microscope utilizing motorized translation stages and linear actuators. The information about automatic control of a microscope stage was obtained from catalogues of the companies Standa and Edmundoptics.
