1. 26. Control of Hybrid Electric Vehicles with Diesel Engines

   Författare :Karin Jonasson; Industriell elektroteknik och automation; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; robotteknik; Automatiska system; simulation; hybrid vehicle; diesel engines; Automation; control engineering; robotics; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : This thesis is an approach to improve electric hybrid vehicles with respect to fuel consumption and to fulfil the future intended NOX emission regulations. It is based upon the conclusions made in the licentiate thesis Analysing Hybrid Drive System Topologies (Jonasson, 2002). LÄS MER

3. 27. Model Based Vehicle Level Diagnosis for Hybrid Electric Vehicles

   Författare :Christofer Sundström; Lars Nielsen; Erik Frisk; Linköpings universitet; []
   Nyckelord :;

   Sammanfattning : When hybridizing a vehicle, new components are added that need to be monitored due to safety and legislative demands. Diagnostic aspects due to powertrain hybridization are investigated, such as that there are more mode switches in the hybrid powertrain compared to a conventional powertrain, and that there is a freedom in choosing operating points of the components in the powertrain via the overall energy management and still fulfill the driver torque request.

4. 28. Fabrication and Characterization of Si-on-SiC Hybrid Substrates

   Författare :Ling-Guang Li; Jörgen Olsson; Örjan Vallin; Stefan Bengtsson; Uppsala universitet; []
   Nyckelord :hydrophilic wafer bonding; silicon on silicon carbide; hybrid substrate; oxygen out-diffusion; Engineering Science with specialization in Electronics; Teknisk fysik med inriktning mot elektronik;

   Sammanfattning : In this thesis, we are making a new approach to fabricate silicon on insulator (SOI). By replacing the buried silicon dioxide and the silicon handling wafer with silicon carbide through hydrophilic wafer bonding, we have achieved silicon on crystalline silicon carbide for the first time and silicon on polycrystalline silicon carbide substrates at 150 mm wafer size.

5. 29. Investigation of a Biofilm Reactor Model with Suspended Biomass

   Författare :Alma Masic; Matematik LTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; wall attachment; suspended growth; substrate removal; reactor; biofilm; CSTR; mathematical model; MBBR; nitrification; optimization;

   Sammanfattning : Biofilms are compact, sessile microbial communities that attach to surfaces in aqueous environments. In wastewater treatment, they are especially important for removal of phosphorus and nitrogen, which, if released into a receiving water body, can cause severe eutrophication. LÄS MER

7. 30. Hybrid observers for systems with intrinsic pulse-modulated feedback

   Författare :Diana Yamalova; Alexander Medvedev; Xiaoming Hu; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid systems; impulsive systems; biomedical systems; Goodwin s oscillator; observers; time-delay; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : Dynamical processes resulting from the interaction of continuous and discrete dynamics are often encountered in living organisms. Time evolutions of such processes constitute continuous variables that are subject to instant changes at discrete points of time. LÄS MER
