  1. 6. Wind Power - Added Value for Network Operation

    Author : Nayeem Ullah; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; torsional oscillation; reactive power ancillary service; voltage stability; power system simulator.; STATCOM; non-minimum phase system; Variable speed wind turbine; frequency control; sensitivity analysis; transient stability; small-signal stability;

    Abstract : This dissertation deals with the investigation on different value added properties of variable speed wind turbines (VSWT) that stem from the flexible controllability of converter interfaced wind turbines (WT). Improvements in voltage and transient stability of a nearby grid, small-signal stability improvement on the power system, frequency control support for the network operation, as well as thetechnical and the economic issues related to the reactive power ancillary service provision, are among the issues covered.

  2. 7. Conversion of xylan into value-added products

    Author : Reza Faryar; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; xylooligosaccharides; biosurfactant; prebiotic; xylan-based film; Lactobacillus brevis;

    Abstract : Today’s high demand on finding sustainable energy sources, replacing petroleum-based products and the needfor healthier food alternatives have forced us to search for natural recoverable resources and explore their manyhidden applications. One such resource is xylan, which has gained much attention as possible raw material forvarious exploitations. READ MORE

  3. 8. Territorial Allocation of VAT in the European Union : Alternative approaches towards VAT allocation and their application in the internal market

    Author : Mariya Senyk; Institutionen för handelsrätt; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; value added tax; origin principle; destination principle; internal market; allocation of tax; added value principle;

    Abstract : When it comes to determining the jurisdictional reach of VAT two principles are used by the OECD, EU policy makers and scholars, namely, the origin principle and the destination principle. These principles can mean different things. READ MORE

  4. 9. Unlocking the Potential of Brewer’s Spent Grain : Sustainable Biorefinery Approach and Value-Added Product Generation

    Author : Mohsen Parchami; Mohammad J Taherzadeh; Sudip Rakshit; Högskolan i Borås; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brewer s spent grain; Hydrothermal pretreatment; Organosolv pretreatment; Edible filamentous fungi; Anaerobic digestion; Biorefinery; Resource Recovery; Resursåtervinning;

    Abstract : Brewer’s spent grain (BSG) constitutes 85% of brewing byproducts and 30% of initial malt. In 2021, BSG production reached approximately 37.2 million tons. Owing to its high moisture and nutritional content, BSG is prone to biological deterioration, causing environmental issues when discarded as waste. READ MORE

  5. 10. Materials Handling from a Value-Adding Perspective

    Author : Birgitta Öjmertz; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ergonomics; value-adding; improvement; performance measurement; materials flow system; activity analysis; materials handling; efficiency;

    Abstract : The keen competition in industry puts a great deal of pressure upon all parts involved, and in addition to demands on the physical product, there are demands on the service aspects, such as an increased demand on the configuration of the delivered materials and their packaging, on throughput time, timeliness, and increased cost efficiency. The performance of the materials flow systems, in which materials handling constitutes an important part, therefore plays a crucial part in the strive for competitive advantage. READ MORE
