  2. 1. 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. 2. Integrating Biomass in Existing Natural Gas-Fired Power Plants

    Author : Erik Pihl; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest Residue; Modeling; Hybrid Combined Cycles; Biomass; Gasification; Efficiency;

    Abstract : Using biomass for utility heat and electricity generation can supplement use of fossil fuels, whose emissions of carbon dioxide likely risk causing serious climate change and ocean acidification. Biomass as energy source is a limited resource and when used as fuel in thermal power plants this currently results in higher production costs than using fossil fuels such as natural gas and coal.

  5. 3. Gendered experiences of work environment : A study of stress and ambiguity among dental students in Sweden

    Author : Ingrid Schéle; Leif Hedman; Anne Hammarström; Eva Bejerot; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; dental students; Swedish dental education; work and organisational theories; gender power relations; ambiguity; perceived stress; satisfaction; grounded theory; content analysis; SEM; cluster analysis; tandläkarstudenter; svensk tandläkarutbildning; arbets- och organisations teorier; genus och makt relationer; ambiguitet; upplevd stress; nöjdhet; grundad teori; innehållsanalys; SEM; kluster analys; Applied psychology; Tillämpad psykologi; Psychology; psykologi;

    Abstract : This thesis explores how dental students experience their education. We aim to generate ways to understand which elements relate to the students’ experience based on current theories and models regarding the quality of working life and gender (and) power relations. READ MORE

  6. 4. Development of a Noise-Based Method for the Determination of the Moderator Temperature Coefficient of Reactivity (MTC) in Pressurized Water Reactors (PWRs)

    Author : Christophe Demaziere; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; point-kinetics; Decay Ratio DR ; Gamma-Thermometer GT ; temperature noise structure of the ; correlation length; boron dilution method; noise analysis; core calculations; dynamic reactor transfer function; moderator temperature coefficient MTC ;

    Abstract : The Moderator Temperature Coefficient of reactivity (MTC) is an important safety parameter of Pressurized Water Reactors (PWRs). In most countries, the so-called at-power MTC has to be measured a few months before the reactor outage, in order to determine if the MTC will not become too negative. READ MORE

  7. 5. Modelling, failure modes prediction and optimization of gear shifting mechanism, Application to heavy vehicle transmission systems

    Author : Muhammad Irfan; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; failure modes prediction.; gear shifting; GT-Suite modelling; optimization; Synchronizer; constrained Lagrangian formalism; sensitivity analysis;

    Abstract : The transmission system has a key role to drive a vehicle transmitting power from engine to rotational motion at wheels. Gear shifting mechanism inside the gearbox is a crucial part of the transmission system. READ MORE
