  1. 16. När lärare formar ett nytt ämnesinnehåll : intentioner, förutsättningar och utmaningar med att införa programmering i skolan

    Författare :Peter Vinnervik; Maria Berge; Johan Lithner; Jan Erik Moström; Arnold Pears; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; programming; compulsory school; curriculum analysis; curriculum enactment; curriculum reform; challenges; technology education; programmering; grundskola; läroplansanalys; läroplansreform; undervisning; utmaningar; teknik; pedagogiskt arbete; educational work;

    Sammanfattning : In March 2017, programming was introduced in the Swedish school curriculum. The reform was formally enacted in July 2018. Research shows that teachers enacting curriculum reform practices encounter various challenges. LÄS MER

  3. 17. Pyrolysis and Detoxification of Waste Electrical and Electronic Equipment (WEEE) for Feedstock Recycling

    Författare :Panagiotis Evangelopoulos; Weihong Yang; Efthymios Kantarelis; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; WEEE; solvent extraction; brominated flame retardants; Tetrabromobisphenol A; Auger reactor; Πυρόλυση; ΑΗΗΕ; εκχύλιση με διαλύτη; βρωμιωμένα επιβραδυντικά φλόγας; Τετραβρωμοδιφαινόλη Α; Pyrolys; WEEE; lösningsmedelsextraktion; bromerade flamskyddsmedel; tetrabrombisfenol A; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The trends in waste electrical and electronic equipment (WEEE) generation shows that their volume constantly increases, while the current waste management technologies have proven to be insufficient in order to meet the strict criteria and the new legislations of the European Union. Pyrolysis and thermal treatment in general could be a valuable solution for closing the loop of materials and could contribute to the energy demands of modern society. LÄS MER

  4. 18. Transition Metals and their Carbides, Nitrides and Carbonitrides : from a CALPHAD Perspective

    Författare :Fredrik Haglöf; Malin Selleby; Andreas Blomqvist; Susanne Norgren; Mauro Palumbo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : The CALPHAD (CALculation of PHAse Diagrams) method consists of three cornerstones, i.e. experiments, computational methods (e.g. LÄS MER

  5. 19. Hardening Distortions of Serial Produced Gears

    Författare :Anders Olofsson; Stefan Jonsson; Julia Gerth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hardening distortions; crown wheel; main shaft gear; gear runout; back-face tilt; macrosegregation; ingot casting; continuous casting; case hardening; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : Hardening distortions are unwanted changes in shape and dimension that arise during hardening of steel components. Uncontrolled distortions induce random errors to the manufacturing process, and have a strong negative impact on manufacturing costs. LÄS MER

  7. 20. Modelling and Management of Uncertainty in Production Systems : from Measurement to Decision

    Författare :Károly Szipka; Andreas Archenti; Sten Dr. Bergstrand; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Precision engineering; Uncertainty modelling; Machin-ing system capability; Production Engineering; Industriell produktion;

    Sammanfattning : The advanced handling of uncertainties arising from a wide range of sources is fundamental in quality control and dependability to reach advantageous decisions in different organizational levels of industry. Es-pecially in the competitive edge of production, uncertainty shall not be solely object of estimation but the result of a systematic management process. LÄS MER
