13. ANÁLISE DE ACIDENTE COM ROTOR: MODELAGEM E SIMULAÇÃO / ROTOR ACCIDENT ANALYSIS: MODELLING AND SIMULATION
A problem related with an air compressor gave birth to the MSc Thesis. Problems related with rotative machines are usual in the industrial field. Difficulties come from the data gathering in order to analyze, and propose a theory of failure in order to explain and avoid the recurrence of such problem. Modelling a rotor with a Timoshenko beam element and the

14. Mutually connected DPLL networks: modelling, simulation and optimization. / Redes mutuamente conectadas de DPLLs: modelagem, simulação e otimização.
Clock-distribution is an essential feature in many engineering applications as, for example, telecommunications networks and digital integrated circuits. In the last few decades this problem was predominantly addressed using master-slave strategies. In this type of strategy there are precise reference oscillators in the network called masters and their signa

15. Estimativa de consumo de energia de cÃdigo ANSI-C para sis- temas embarcados: uma abordagem baseada em simulaÃÃo estocÃstica
Embedded Systems are present in most daily activities with many different purposes. Generally, embedded systems have several design constraints, such as memory size, power source, CPU speed, and so on. Over the last years, power consumption has been receiving particular attention from scientific community since several embedded devices rely on battery as pow

16. Estudos de relações entre variáveis socioeconômicas, de uso do solo, participação em atividades e padrões de viagens encadeadas urbanas / Study of relationships between socioeconomic, land use, activity participation variables and trip-chaining urban patterns
One of the most important topics in transportation demand is the relationship between individual needs to carry out geographically distributed activities, urban configuration, individual and household characteristics, transportation system and travel behavior. For that reason, the main aim of this work is to analyze the individual trip-chaining behavior in t

17. Traffic modelling, policing and scheduling in Ethernet passive optical networks / Modelagem, policiamento e escalonamento em redes Ethernet PON
We propose new framework for traffic modelling, policing and scheduling in Ethernet Passive Optical Networks. This framework aims at providing performance guarantees to individual flows in access networks. We propose a new envelope process called Fractional Bounded Arrival Process for selfsimilar multimedia traffic representation. The policing of such a kind

18. DiagnÃstico em modelos simÃtricos de regressÃo
The statistical modelling using the assumption of normally distributed errors can be strongly influenced by extreme observations. This motivates the study on regression techniques that are roobust in presenceof this type pof observations. As an alternative, models in wich the error term belongs to the symmetrical class can be considered. This class of models

19. "Índices de carga e desempenho em ambientes paralelos/distribuídos - modelagem e métricas" / Load and Performance Index for Parallel/Distributed System - Modelling and Metrics
This thesis approaches the problem of evaluating an adequate load index or a performance index, for using in process scheduling in heterogeneous parallel/distributed computing systems. A wide literature review with the corresponding critical analysis is presented. This review is the base for the comparison of the existing metrics for the evaluation of the co

20. Modelagem matemática de correntes na torre da estação Morro do Cachimbo (Brasil). / Mathematical modelling of current in the Morro do Cachimbo station tower (Brazil).
The effect of an elevated strike object on the measured current in the top and the bottom of Morro do Cachimbo (MCS) station instrumented tower is modeled, considering a current divisor applied at the tower top, and that the channel current is supplied by the current source located at the attachment point. The mathematical formulations of the engineering mod

21. ASDA: um ambiente de simulação distribuída automático / ASDA: an automatic distributed simulation environment
Esta tese propõe um ambiente automático para desenvolvimento de simulação distribuída ASDA (Ambiente de Simulação Distribuída Automático), que tem como objetivo principal facilitar a utilização e desenvolvimento de simulação distribuída. As funcionalidades definidas no ASDA tornam-o diferente de todos os outros ambientes encontrados na literatu

22. Aplicación del metodo geoelectrico para la determinacion de horizontes salinos en la colonia lloveras - pcia de San Juan - Argentina
To locate and, if possibly, delimitate the presence of underground saline saturated horizons at Colonia Lloveras, 25 de Mayo department in San Juan province, Argentine Republic; a geoelectric research using the Vertical Electrical Sounding (VES) method has been programmed and actually carried out. A first step consisted on the execution of 10 V.E.S. as evenl

23. Avaliação de arquiteturas de comando : aplicação a um sistema automatizado de produção industrial
The design phase of Automatic Manufacturing Systems comprises many different tasks and among them stands the design of a control architecture. Actually for highly distributed control systems the choice for a specific architecture has great impact on the overall system s life cyc1e. In such cases the designer has to propose early enough in the system s design

24. Contributions to an Anthropological Approach to the Cultural Adaptation of Migrant Agents
This thesis proposes the use of Cultural Anthropology as a source of inspiration for solutions to the problem of adaptation of autonomous, intelligent, computational agents that migrate to societies of agents with distinctive features from the ones of the society where those agents were originally conceived. This has implications for interoperation of dispar
