1. OPTIMAL TRAJECTORY DEFINITION AND CONTROL FOR A TERRESTRIAL VEHICLE IN A CLOSED TRACK / DETERMINAÇÃO E CONTROLE DA TRAJETÓRIA ÓTIMA DE UM VEÍCULO TERRESTRE EM TRAÇADO FECHADO PRÉ-DEFINIDO
The definition of the minimum time trajectory in a track is not obvious, since it is directly dependent on the acceleration limits that the vehicle can withstand. This paper presents an optimization method based on Genetic Algorithms that identifies the path that a car must follow in order to complete a given circuit in minimum time. By considering an Orient

2. ESTRATÉGIAS DE CONTROLE APLICADAS AO PROBLEMA DE DIRIGIBILIDADE DE VEÍCULOS TERRESTRES EM TRAJETÓRIAS FECHADAS PRÉ-DEFINIDAS / CONTROL STRATEGIES APPLIED TO GROUND VEHICLES HANDLING PROBLEM IN PRE-DEFINED CLOSED TRAJECTORIES
Apresenta-se o uso das ferramentas lineares de Controle Clássico (Lugar Geométrico das Raízes) e Moderno (Realimentação de Estado e de Saída e Alocação de Pólos) para estabelecer os ajustes dos controladores adotados no problema de acompanhamento de trajetórias em traçados fechados por veículos terrestres, procurando reproduzir o comportamento do

3. Cumulative concentrations of blood lead and postural stability.
OBJECTIVE: To study the association in a group of battery manufacturing workers between computerised postural sway parameters and present concentrations of blood lead (PPb), index of cumulative blood lead years (CBI), and cumulative blood lead at different years of exposure (CPbYs). METHODS: Postural stability was investigated with a computerised postural sw

4. Postural stability of workers exposed to lead.
OBJECTIVE--To detect, with a computerised postural sway measurement system, any significant deviation of postural sway parameters among lead workers compared with a control group. METHODS--Postural stability was investigated with a computerised postural sway measurement system in 60 workers exposed to lead with a duration of exposure of 84 (range 3-366) mont
