  1. 11. Towards Sustainable Improvement Systems

    Författare :Dag Swartling; Lars Witell; Bozena Poksinska; Yvonne Lagrosen; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Improvements in general and sustainable improvements in particular are problematic areas. The failure rate is high, figures in the vicinity of 70 percent are often mentioned, but why is it so difficult to achieve sustainable improvement systems? The purpose of this dissertation is to contribute to understanding of the process and its mechanisms in creating a sustainable improvement system. LÄS MER

  3. 12. The effect of microstructural features, defects and surface quality on the fatigue performance in Al-Si-Mg Cast alloys

    Författare :Toni Bogdanoff; Ehsan Ghassemali; Salem Seifeddine; Anders E.W. Jarfors; Ru Peng; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminum-Silicon alloys; defects; material characterization; fatigue performance; digital image correlation;

    Sammanfattning : Global warming is driving industry to manufacture lighter components to reduce carbon dioxide (CO2) emissions. Promising candidates for achieving this are aluminium-silicon (Al-Si) cast alloys, which offer a high weight-to-strength ratio, excellent corrosion resistance, and good castability. LÄS MER

  4. 13. DFT calculations of initial localized corrosion of aluminum : Influence of aqueous ad-layer, chloride ions, and intermetallic particles

    Författare :Min Liu; Jinshan Pan; Ying Chen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aluminum alloys; alumina; chloride; surface adsorption; aqueous ad-layer; localized corrosion; corrosion initiation; work function; micro-galvanic effect; density-functional theory; Volta potential; scanning kelvin probe force microscopy; Kemi; Chemistry;

    Sammanfattning : Localized corrosion of aluminum (Al, here including Al alloys) involves a series of physico-chemical processes at the interface between the metal and the aqueous ad-layer or the aqueous solution. The mechanisms that govern localized corrosion are quite complex and have been the subject of many experimental studies. LÄS MER

  5. 14. Lost in Translation : A case of BIM implementation at a large public client

    Författare :Hannes Lindblad; Väino Tarandi; Henrik Linderoth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology driven change; Building information modelling; BIM; Sociology of translation; Implementation; Innovation; Actor-Network theory; Real Estate and Construction Management; Fastigheter och byggande;

    Sammanfattning : The technology of Building Information Modelling (BIM) is being introduced to the Architectural, Engineering and Construction (AEC) industry. This industry is generally perceived as being fragmented, having low productivity and with a low rate of innovation. LÄS MER

  7. 15. Chemical Pathways to Electrically Conductive Hemicellulose Hydrogels

    Författare :Weifeng Zhao; Ann-Chiristine Albertsson; Ulrica Edlund; Karin Odelius; Elisabet Brännvall; Peter Plikk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Electrically conductive; hemicellulose; hydrogels; swelling behavior; aniline oligomers; renewable; polymer synthesis; Elektriskt ledande; hemicellulosa; hydrogel; svällning; anilinoligomerer; förnyelsebar; polymersyntes; Kemi; Chemistry;

    Sammanfattning : Hydrogels have been extensively explored and are widely used in diverse biomedical applications, such as scaffolds for tissue engineering and vehicles for drug delivery. As one type of important natural polymer-based hydrogel, hemicellulose hydrogels have interesting attributes, including being renewable, non-toxic, biocompatible, biodegradable, and abundantly available.
