    Sammanfattning : Energy use in the urban environment is vital for the proper functioning of our society, and in particular, comfort heating –or cooling– is a central element of our energy system often taken for granted. Within this context, district energy systems and especially, district heating (DH) systems must evolve to adapt to the upcoming decades-long transition towards a sustainable energy system. LÄS MER

  3. 17. Integration and communication of engineering information in collaborative design

    Författare :Haoxue Ma; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : In recent years, the rapid development of computer technologies has greatly impacted the product development process. In the engineering area, powerful computer-based tools such as Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) systems enable engineers to fulfil various design tasks and realise product concepts in the early phase of the product development process, without physical parts actually being manufactured.

  4. 18. Configuration of modularised building systems

    Författare :Patrik Jensen; Miklos Molnar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

    Sammanfattning : Swedish building industry is mainly project-oriented where the design process is sequential involving various disciplines separated both in time and space. During the last decades the industry has been criticised and accused of having problems with quality and low productivity. LÄS MER

  5. 19. Bioprocess development for biochemical conversion of lignocellulose

    Författare :Ruifei Wang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignocellulose; strain engineering; stress tolerance; kinetic modelling; high gravity; scale-up; biofuels; SSCF; process development; Saccharomyces cerevisiae;

    Sammanfattning : Due to its low environmental impact and high maturity of the fuel ethanol market, lignocellulosic ethanol is a promising option for reducing the carbon footprint in the transport sector. The characteristics of lignocellulosic feedstocks, such as varied sugar composition, low sugar density, low solubility, recalcitrance to enzymatic degradation, and inhibitors formed during thermochemical pretreatment, have so far limited the production process, and costs for conversion of lignocellulosic materials to ethanol are still high.

    Sammanfattning : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. LÄS MER
