  2. 6. Novel application of membrane bioreactors in lignocellulosic ethanol production : simultaneous saccharification, filtration and fermentation (SSFF)

    Author : Mofoluwake M. Ishola; Högskolan i Borås; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biofuel; Ethanol; Membrane bioreactors; High solids loading; Lignocellulose; Nigeria; Pretreatment; SSFF; Saccharomyces cerevisiae; Resource Recovery; Resursåtervinning; Resource Recovery;

    Abstract : Biofuels production and utilisation can reduce the emission of greenhouse gases, dependence on fossil fuels and also improve energy security. Ethanol is the most important biofuel in the transportation sector; however, its production from lignocelluloses faces some challenges. READ MORE

  4. 7. Simultaneous localization and mapping with robots

    Author : John Folkesson; Henrik I. Christensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computer science; Computer science; Datalogi;

    Abstract : A fundamental competence of any mobile robot system is the ability to remain localized while operating in an environment. For unknown/partially known environments there is a need to combine localization with automatic mapping to facilitate the localization process. READ MORE

  5. 8. Modelling and simulation of simultaneous forming and quenching

    Author : Greger Bergman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Abstract : The objective of this thesis is to develop and evaluate numerical methods for modelling and simulation of simultaneous forming and quenching within an integrated product development environment. Simultaneous forming and quenching, also referred to as hot-stamping, is a manufacturing process for high strength automotive components such as side impact protection beams. READ MORE

  6. 9. Migration and Perceptions of War : Simultaneous Surveys in Countries of Origin and Settlement

    Author : Jonathan Hall; Ashok Swain; Cochrane Feargal; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; civil war; migration; refugees; gastarbeiter; family reunification; exile; trauma; coping; nostalgia; conservation of resources; terror management theory; social identity complexity; assimilation; acculturation; surveys; Peace and Conflict Research; Freds- och konfliktforskning;

    Abstract : This dissertation contributes to post-war public opinion research by examining the perceptions of migrants – the gastarbeiter, the refugee, the family reunited after war – and the local population in comparative perspective. Existing surveys of post-war populations are typically conducted in a single country affected by war. READ MORE

  7. 10. Designing simultaneous saccharification and co-fermentation of lignocellulose for improved xylose conversion

    Author : Kim Olofsson; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bioethanol; lignocellulose; simultaneous saccharification and co-fermentation; xylose fermentation;

    Abstract : Fuel ethanol from lignocellulose is one sustainable alternative to the fossil fuels of today. All sugars in the material must be utilized in order to achieve high overall ethanol yields. Baker’s yeast, Saccharomyces cerevisiae, has been engineered to ferment the pentose sugar xylose from lignocellulose to ethanol. READ MORE
