    Abstract : 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. READ MORE

  4. 7. Grammar and grammaticalization in Manda: An analysis of the wider TAM domain in a Tanzanian Bantu language

    Author : Rasmus Bernander; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; Manda; Bantu; southern Tanzania; grammaticalization; grammar; linguistic description; reconstruction; tense-aspect-mood; modality; negation; auxiliary;

    Abstract : This dissertation offers a grammatical description and analysis of Manda (N.11), a Bantu language spoken along Lake Nyasa (Lake Malawi) in southern Tanzania. The study focuses on the “wider” TAM domain, i.e. READ MORE

  5. 8. High Frequency Model of Electrified Railway Propulsion System for EMC Analysis

    Author : Kelin Jia; Rajeev Thottappillil; Hans Bängtsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromagnetic compatibility; railway; propulsion system; multitransmission line; ac motor modeling; vector fitting; fast transient;

    Abstract : A model of the electrified railway propulsion system working in a wide frequency range is studied in this thesis. The high frequency modeling is the first stage to study and predict the Electromagnetic compatibility (EMC) problems in the electrified railway propulsion system, which are safety and reliability issues of high concern.

  6. 9. Aerodynamics of an Aeroengine Intermediate Compressor Duct: Effects from an Integrated Bleed System

    Author : Elias Siggeirsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermediate Compressor Duct; S-shaped duct; DDES; Hybrid RANS LES; Dual-time-stepping; Bleed system; rotor off-take; SBES; CFD; Turbomachinery;

    Abstract : With the successful development of high-bypass-ratio turbofan engines, major aerodynamic components have been optimized and continuous efficiency improvements are getting harder to maintain. Therefore, to meet the requirements of lower emission of greenhouse gases, auxiliary modules such as intermediate ducts are receiving increasing interest. READ MORE

  7. 10. Development of the CHICSi multi detector system and experiments with its auxiliary systems

    Author : Elbert Jan van Veldhuizen; Uppsala universitet; []
