6. Aquarius II â Uma plataforma para desenvolvimento de sistemas dinamicamente reconfigurÃveis baseada no sistema operacional uCLinux
The programmable logic devices, FPGAs (Field Programmable Gate Arrays) have been used for a long time as tools for digital circuits prototyping. However, this reality has changed since the computational power of these devices increased and cost decreased. Besides, the FPGAs in use nowadays consume less energy than a conventional CPU to do the same work. Anot

7. Uma arquitetura para monitoramento e medição de desempenho para ambientes virtuais
Virtual environments are experiencing a renewed interest due to several reasons, such as isolation, server consolidation and resource partitioning. The deployment of a virtual server allow the consolidation of multiple operational systems and applications on a single hardware platform, reducing the number of servers of an enterprise, increasing resource util

8. THE REAR CAR SEAT SAFETY BELT: AN ERGONOMIC APPROACH / CINTO DE SEGURANÇA DO BANCO TRASEIRO DO AUTOMÓVEL: UMA ABORDAGEM ERGONÔMICA
This study is developed based on the hypothesis that the deficiencies of project of the package for the automobile`s rear passengers, as well as of the rear seat safety-belt itself, from the ergonomic point of view, cause discomfort and constrain people to its usual use. Therefore, its rejection or misuse have been subjecting the passengers to injuries and e

11. The Effects Of A Seatbelt-gearshift Delay Prompt On The Seatbelt Use Of Motorists Who Do Not Regularly Wear Seatbelts
A seatbelt-gearshift delay was evaluated in two U.S. and three Canadian vehicles using a reversal design. The seatbelt-gearshift delay required unbelted drivers either to buckle their seatbelts or to wait a specified time before they could put the vehicle in gear. After collecting behavioral prebaseline data, a data logger was installed in all five vehicles

12. High levels of incorrect use of car seat belts and child restraints in Fife--an important and under-recognised road safety issue.
OBJECTIVE: To pilot data collection instruments and to make a preliminary estimate of the level of incorrect use of car seat belts and child restraints in Fife, Scotland. DESIGN: Cross sectional survey of cars containing adults and children at a number of public sites across Fife in 1995 to assess use of car occupant restraints. Trained road safety officers
