  2. 11. The Pneumatic Hybrid Vehicle - A New Concept for Fuel Consumption Reduction

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VVA; Regenerative; Air-motor; Compressor; Pneumatic; Hybrid; Vehicle; Electric Hybrid; Drive Cycle; GT-Power; Simulink; FPGA;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional internal combustion engines (ICE) could be saved, the fuel economy would improve. READ MORE

  4. 12. Safety and mobility of children crossing streets as pedestrians and bicyclists

    Author : Charlotta Johansson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Traffic Engineering; Trafikteknik;

    Abstract : The content of this thesis is safety and mobility of children crossing streets as pedestrians and bicyclists. The risk of fatal injury is higher for pedestrians and bicyclists, especially for children and elderly, than for other road users except motorcyclists. READ MORE

  5. 13. Muscle Responses in Dynamic Events. Volunteer experiments and numerical modelling for the advancement of human body models for vehicle safety assessment

    Author : Jóna Marin Olafsdottir; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pre-crash dynamics; spatial tuning patterns; occupant kinematics; electromyography.; Traffic safety; muscle activity; human body models;

    Abstract : Fatalities and injuries to car occupants in motor vehicle crashes continue to be aserious global socio-economic issue. Advanced safety systems that provide improvedoccupant protection and crash mitigation have the potential to reduce this burden. READ MORE

  6. 14. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System

    Author : Sasa Trajkovic; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compressor; Air-motor; Pneuamtc; Pneumatic-hybrid; VVT; Valve; regenerative; Hybrid; Air;

    Abstract : Urban traffic involves frequent acceleration and deceleration. During deceleration, the energy previously used to accelerate the vehicle is mainly wasted on heat generated by the friction brakes. If this energy that is wasted in traditional IC engines could be saved, the fuel economy would improve. READ MORE

  7. 15. Obstructive sleep apnea : the relationship to cardiovascular disease, diabetes mellitus, motor vehicle driving and ambient temperature

    Author : Fredrik Valham; Karl A Franklin; Jan Hedner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstructive sleep apnea. Snoring. Cardiovascular disease. Stroke. Diabetes mellitus. Traffic accidents. Ambient temperature.; medicin; Medicine;

    Abstract : Background: Obstructive sleep apnea is a common disorder, especially in men. Patients with this condition often snore and suffer from excessive daytime sleepiness. It is a treatable condition related to cardiovascular disease, road traffic accidents and obesity. READ MORE
