1. 1. Cognitive and Self-Adaptive SoCs with Self-Healing Run-Time-Reconfigurable RecoBlocks

   Författare :Byron Navas; Ingo Sander; Johnny Öberg; Michael Hübner; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In contrast to classical Field-Programmable Gate Arrays (FPGAs), partial and run-time reconfigurable (RTR) FPGAs can selectively reconfigure partitions of its hardware almost immediately while it is still powered and operative. In this way, RTR FPGAs combine the flexibility of software with the high efficiency of hardware. LÄS MER

3. 2. On Auxiliary Systems in Commercial Vehicles

   Författare :Christian Andersson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Miljöteknik; simalation model; auxiliary system; vehicle; hybrid driveline; Road transport technology; Vägtransportteknik; pollution control; Environmental technology; kontroll av utsläpp; Energy research; Energiforskning;

   Sammanfattning : As more and more focus is put on the environmental questions and the request for cleaner transportation the demand on the vehicles increases. Especially the environmental request of the public transportation that is visible to the public and operates in the centre of the city. The demand on the buses used for public transportation will increase. LÄS MER

4. 3. Troubleshooting Trucks : Automated Planning and Diagnosis

   Författare :Håkan Warnquist; Patrick Doherty; Jonas Kvarnström; Louise Travé-Massuyès; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automated planning; diagnosis; troubleshooting; automotive systems; Bayesian networks; Markov decision-processes;

   Sammanfattning : This thesis considers computer-assisted troubleshooting of heavy vehicles such as trucks and buses. In this setting, the person that is troubleshooting a vehicle problem is assisted by a computer that is capable of listing possible faults that can explain the problem and gives recommendations of which actions to take in order to solve the problem such that the expected cost of restoring the vehicle is low.

5. 4. On design methods for mechatronics : servo motor and gearhead

   Författare :Fredrik Roos; Jan Wikander; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; mechatronics design methodology; servo systems; electric motors; gears; auxiliary systems; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

   Sammanfattning : The number of electric powered sub-systems in road-vehicles is increasing fast. This development is primarily driven by the new and improved functionality that can be implemented with electro-mechanical sub-systems, but it is also necessary for the transition to electric and hybrid-electric drive trains.

7. 5. Hydrogen Generation for Fuel Cells in Auxiliary Power Systems

   Författare :Marita Nilsson; Lars J. Pettersson; Gunther Kolb; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; autothermal reforming; auxiliary power unit; diesel; dimethyl ether; fuel cell; fuel-flexible reformer; hydrogen; PdZn alloy; reforming catalyst; reformer design; Rh; Chemical engineering; Kemiteknik;

   Sammanfattning : Heavy-duty trucks are in idle operation during long periods of time, providing the vehicles with electricity via the alternator at standstill. Idling trucks contribute to large amounts of emissions and high fuel consumption as a result of the low efficiency from fuel to electricity. LÄS MER
