1. Braquistócrona na esfera
Abstract O problema consiste em determinar a trajetória (entre dois pontos dados) de menor tempo de um corpo, que parte do repouso, restrito a se mover numa superfície esférica e sujeito a um campo gravitacional constante. Através da equação de Euler-Lagrange, obtém-se uma expressão para o tempo total de percurso. O problema foi resolvido numericamen

2. O valor do tempo na avaliação de projetos de transportes
The aim of this study is to analyse road congestion, especially considering structural aspects and the scenarios for the future. It emphasizes the possibility of using special tools for facing these problems which affect medium and biggest cities. Although traffic restrictions are major tools to face congestion, they have presented some problems when used in

3. MODELANDO VALOR DE TEMPO DE VIAGEM PARA MODOS CONCORRENTES POR DIFERENTES MODELOS LOGIT: O QUE SE GANHA E O QUE SE PERDE? / MODELING VALUE OF TRAVEL TIME TO COMPETITORS BY DIFFERENT WAYS LOGIT MODELS: WHAT YOU WIN AND LOSE THAT?
Economistas desde 1965 debruÃam-se sobre uma forma de como mensurar o valor do tempo. O trabalho de Tuong e Hensher (1985) uniu teoria ao empirismo, entretanto, com o passar dos anos os mÃtodos diversos de estimaÃÃo por modelos de escolha discreta nÃo foram utilizados para a mediÃÃo do valor de tempo de viagem. Esta tese mensura o valor de tempo de vi

4. Lazer e processos educativos : mergulhos culturais na Bacia do Salto
This study was conducted with thirteen participants dips and jumps in the Bacia do Salto do Rio Jacaré, site located at Parque dos Saltos in Brotas city, small town of São Paulo state. The social practice of dips and jumps in Bacia, culturally developed by residents of the city since childhood, which is presented as a breach of the established commercially

5. Atividade fisica e fragilidade em idosos da comunidade : dados do FIBRA Campinas / Physical activity and frailty in community dwelling elderly ; : data from the study FIBRA Campinas
There is consensus on the importance of physical activity for health promotion for older people, but there is controversy about the methods to evaluate it, just as there are difficulties to discriminate between the effects of health variables and and behavioral variables on your practice. Objective: Examining relationships between frailty indicated by weight

6. Dynamic generation metodology of road travel patterns to vehicles intelligent monitoring in AVL systems. / Metodologia de geração dinâmica de padrões de viagens rodoviárias para monitoramentos inteligentes de veículos de carga em sistemas AVL.
This dissertation addresses the question of vehicle travel adherence in intelligent monitoring with Automatic Transportation Location (AVL) operating in a regional environment. A trip is considered as series of runs, corresponding to time in movement but excluding time spent on activities such as loading/unloading and others. Based on historic data collected

7. Aplicação de um procedimento usando preferência declarada para a estimativa do valor do tempo de viagem de motoristas em uma escolha entre rotas rodoviárias pedagiadas e não pedagiadas. / Application of a procedure using stated preference for value of travel time estimation in a choice context involving tolled and non-tolled routes.
This dissertation is based on the application of an empirical procedure using stated preference techniques for the estimation of the value of travel time for drivers in regional trips, in the context of a choice between tolled and non-tolled routes. It first reviews the theoretical and the empirical approaches for the valuation of travel time and then presen

8. Proposta de um método para a definição de rotas cicláveis em áreas urbanas.
Urban problems caused by transportation planning that prioritizes the use of the automobile indicate the inclusion of the bicycle as a viable alternative of urban transport in Brazilian cities. However, it is verified the lack of guidelines that can lead to policies that encourage bicycle transportation, amongst which stands out the insertion or improvement

9. Self-tuned vehicle parameters detection and estimation from vÃdeo sequences for traffic incident management.
This work proposes and compares three algorithms for vehicle detection, composed of two main stages, preprocess and process. The first will proceed with the selection of the region of interest (ROI) and the background learning phase. The ROI is a narrow and transversal-to-lane rectangular area wherein detection is achieved, its dimensions provides low proces

10. A variational formulation to image inclusions in 2D travel time cross hole tomography
It was developed a simple and high speed method with the purpose to model inclusions of irregular forms (simply connected and convex domain) in the context of cross hole travel time 2D tomography. The extension to 3D can be easily implemented and is not covered in this paper. The following assumptions were made: a) Homogeneus host medium (therefore straight

11. Factors that describe a successful rural entrepreneur. / Caracterização dos fatores relacionados ao sucesso de um empreendedor rural.
In order to identify the factors that describe a successful rural entrepreneur, three focus groups were conduced with farmers and extension agents of the Wheat Cooperative of Alto Jacui Cotrijal at Não-Me-Toque, Rio Grande do Sul State. Several variables were suggested as playing important roles in explaining why a farmer is considered successful or not,

12. Estudo sísmico no açude Tucunduba, Senador Sá, CE
The Tucunduba Dam, is west of Fortaleza, Ceará State. The seismic monitoring of the area, with an analogical station and seven digital stations, had beginning on June 11, 1997. The digital stations, operated from June to November 1997. The data collected in the period of digital monitoring was analyzed for determination of hypocenters, focal mechanisms, and
