1. Speciation and Metabolic rate : Insights from an avian hybrid zone
Sammanfattning : The role of divergent climate adaptation in speciation has received surprisingly little scientific attention. My dissertation research focused on how resting metabolic rate (RMR) relates to the build up of prezygotic and postzygotic isolation in a natural Ficedula flycatcher hybrid zone. LÄS MER
2. The Four-Quadrant Transducer System : for Hybrid Electric Vehicles
Sammanfattning : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype. The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle. LÄS MER
3. Designing Human-Centered Hybrid Decision Support Systems
Sammanfattning : Innovative decision support systems (DSSs) are revolutionizing key processes in organizations. These systems are used in managerial decision-making to solve increasingly complicated decision tasks, for example, using artificial intelligence. LÄS MER
4. Towards sustainable urban transportation : Test, demonstration and development of fuel cell and hybrid-electric buses
Sammanfattning : Several aspects make today’s transport system non-sustainable: • Production, transport and combustion of fossil fuels lead to global and local environmental problems. • Oil dependency in the transport sector may lead to economical and political instability. LÄS MER
5. Study of a Pneumatic Hybrid aided by a FPGA Controlled Free Valve Technology System
Sammanfattning : 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. LÄS MER
