1. Aço de alta dureza para aplicação balística: propriedades mecânicas
RESUMO Blindagens balísticas são projetadas a resistir determinadas ameaças, que dependem da aplicação. Estas ameaças podem ser geradas por projéteis de armas de fogo ou estilhaços provenientes de explosões com diferentes energias cinéticas. Os materiais normalmente utilizados para este propósito são metálicos, não metálicos e compósitos, sen

2. Adaptive Filtration of Parameters of the UAV Movement Based on the TDOA-Measurement Sensor Networks
ABSTRACT: In modern conditions unmanned aerial vehicles (UAVs) generate new classes of threats, including their use for terrorist purposes. A feature of modern UAVs is the ability to perform sudden maneuvers and to keep the same position in the point in space. For the description of the UAV movement with various types of maneuver it is used a rectangular coo

3. Wheel-flat detection on trams using envelope analysis with Hilbert transform
Abstract The wheel-flat defect is one of the many issues decreasing the level of and comfort in light rail vehicles. The two main causes of wheel-flats are temporary or complete wheel blocking. The negative effect is the increase of the dynamic phenomenons in the wheel-rail interaction, which are impulsive in their nature. It could prove to be dangerous for

4. Implementação de um programa computacional para auxilio ao projeto de freios automotivos utilizando técnicas de metodologia de projeto / Implementation of a computer program to aid the design of automotive brakes using techniques of the design methodology
This work presents the development of the informational and preliminary design phases to friction brakes applied to urban vehicles of low cost. The design development of the brake systems for vehicles with less or zero pollutants emissions, with high efficiency depends strongly of the control systems, dirigibility conditions and mainly of the solutions to th

5. Dynamic response analysis of single-span guideway caused by high speed maglev train
High speed maglev is one of the most important reformations in the ground transportation systems because of its no physical contact nature. This paper intends to study the dynamic response of the single-span guideway induced by moving maglev train. The dynamic model of the maglev train-guideway system is established. In this model, a maglev train consists of

6. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

7. PROJETO E CONTROLE ROBUSTO DE UM TRANSPORTADOR PESSOAL ROBÓTICO AUTO EQUILIBRANTE / DESIGN AND ROBUST CONTROL OF A SELF-BALANCING PERSONAL ROBOTIC TRANSPORTER VEHICLE
A Self Balancing Personal Transporter (SBPT) is a robotic platform with two wheels that functions from the balance of the individual who uses it, resembling the operation of classic inverted pendulum. In this thesis, a SBPT is designed, built and controlled. Among the features from the developed SBPT, it can be mentioned: relatively high speeds, agility, com

8. Construção e validação de um receptor GPS para uso espacial
O Sistema de Posicionamento Global, conhecido mundialmente pala sigla GPS, é um sistema de radionavegação construído pelos norte-americanos com intenções militares, mas que encontraram, com o passar do tempo, muitas aplicações de uso civil. No Brasil, além do desenvolvimento de foguetes de sondagem, começam a aparecer projetos de construção de mi

9. Influência da utilização do ABS na segurança veicular baseada na eficiência de frenagem e na probabilidade de travamento de roda / Influence if the ABS use on vehicular safety based on braking efficiency and on the probability of wheel lockup
The ABS (Antilock Braking System) is a supplementary system to the regular service brake system, which prevents the wheel lock in any braking situation, mainly in emergency braking maneuvers, and it will guarantee stability and steerability of the vehicle and reduces, in most of the situations, the stopping distance in relation to the regular brake system. B

10. Sistema supervisorio de gestão de multiplas fontes de suprimento para aplicações em veiculos eletricos / Energy management supervisory system of multiple power sources for electric vehicle applications
This work introduces an Energy Management strategy, for electrical vehicle applications, based on a fuzzy logic supervisory system that is able to combine three different power supply sources, i. e., fuel cell, battery and supercapacitor. The supervisory system coordinates the power flow between the power sources so that the system is able to provide high po

11. Otimização do volume e análise estrutural de caçamba para caminhão fora-de-estrada
The transport of ore and dirty, represents the highest costs component in the mining business. In the majority of cases, this transport is executed by off-road trucks with capacities varying from 20 to 400 tons. Due to the high acquisition and maintenance costs involved, as well as to the risks associated, great effort have been made during the last ten year

12. RemoÃÃo de Enxofre da Gasolina em Coluna de Leito Fixo, com uso de Adsorventes ZeolÃticos
The emission of poisons like SOx and hydrocarbons from automotives vehicles is at the moment one of the major sources of atmospheric pollution. The SOx, for instance, is responsible for corrosion in cars, industrial facilities and acid rains. So, during the last years the environmental protection agencies have reduce drastically the levels of permitted emiss
