1. 16. Human mobility behavior : Transport mode detection by GPS data

   Författare :Paria Sadeghian; Johan Håkansson; Xiaoyun Zhao; Kenneth Carling; Gyözö Gidofalvi; Högskolan Dalarna; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Transport mode detection; Machine learning; Statistical learning; Rule-based method; Data labeling;

   Sammanfattning : GPS tracking data are widely used to understand human travel behavior and to evaluate the impact of travel. A major advantage with the usage of GPS tracking devices for collecting data is that it enables the researcher to collect large amounts of highly accurate and detailed human mobility data. LÄS MER

3. 17. Thermo-Acoustic Properties in Combustion Chambers

   Författare :Guillaume Jourdain; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mode Stability Analysis; Computational Aeroacoustics; Screech mode; Arnoldi s Method; Buzz mode; Afterburner; Gas turbine combustor; Combustion instabilities;

   Sammanfattning : Design and analysis methods for gas turbine combustors or afterburners have to be improved in particular regarding the prediction of combustion instabilites. A methodology, which combines the use of a linearized flow solver and an Arnoldi algorithm performing the eigenmode extraction procedure, resolves eigenmodes which are candidates to these instabilities.

4. 18. Microbial Production of Bio-Based Chemicals: A Biorefinery Perspective

   Författare :Tarek Dishisha; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biorefinery; platform chemical; organic acid; propionic acid; 3-hydroxypropionic acid; 3-hydroxypropionaldehyde; methacrylic acid; 1; 3-propanediol; Propionibacterium acidipropionici; Lactobacillus reuteri; Gluconobacter oxydans; high cell density fermentation; biotransformation; product inhibition; cell recycle; immobilized cells; chemical catalysis; pdu operon;

   Sammanfattning : A shift from fossil- to renewable biomass feedstock for the emerging bio-based economy requires the development and adoption of new sustainable technologies that are more suited for transformation of biomass components to chemicals, materials and energy. This thesis presents investigations on the development of processes based on industrial biotechnology as a key element for the production of chemicals from agro-/industrial by-products. LÄS MER

5. 19. Photonic devices with MQW active material and waveguide gratings : modelling and characterisation

   Författare :Nadeem Akram; Lars Thylén; Hartmut Hillmer; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Method of Lines; Grating; ARROW Waveguide; Semiconductor laser; quantum well; Photonics; Fotonik;

   Sammanfattning : The research work presented in this thesis deals with modelling, design and characterisation of passive and active optical waveguide devices. The rst part of the thesis is related to algorithm development and numerical modelling of planar optical waveguides and gratings using the Method of Lines (MoL). LÄS MER

7. 20. Meningsskapandets möjligheter : multimodal teoribildning och multiliteracies i skolan

   Författare :Petra Magnusson; Malmö högskola; []
   Nyckelord :HUMANITIES; HUMANIORA; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Design; design authority; design process; design-theoretical perspective; discourse; ethnography; fiction; learning design sequence; literacy; media; media ecology; mode; multimodal; meaning; meaning-making; meaning-offering; multiliteracies; reading; socio cultural; design;

   Sammanfattning : This thesis concerns the changing predispositions and conditions for contemporary meaning-making in school education. From a socio-cultural perspective, multimodal theory formation is used to find suitable tools and concepts for developing teaching and learning. LÄS MER
