  3. 3. Additive Manufacturing using Alloy 718 Powder : Influence of Laser Metal Deposition Process Parameters on Microstructural Characteristics

    Author : Andreas Segerstark; Joel Andersson; Lars-Erik Svensson; Robert Pedersen; Högskolan Väst; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Laser metal deposition; powder; superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Additive manufacturing (AM) is a general name used for production methodswhich have the capabilities of producing components directly from 3D computeraided design (CAD) data by adding material layer-by-layer until a final component is achieved. Included here are powder bed technologies, laminated object manufacturing and deposition technologies. READ MORE

  4. 4. Models for Additive and Sufficient Cause Interaction

    Author : Daniel Berglund; Timo Koski; Helga Westerlind; Ola Hössjer; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Causal Inference; Sufficient Cause; Potential Outcomes; Counterfactual; Additive Interaction; Interaction; MFPO; ICI; Logistic Regression; Linear Odds; Public Health; Interventions; Probabilistic Potential Outcome; Mathematical Statistics; Matematisk statistik;

    Abstract : The aim of this thesis is to develop and explore models in, and related to, the sufficient cause framework, and additive interaction. Additive interaction is closely connected with public health interventions and can be used to make inferences about the sufficient causes in order to find the mechanisms behind an outcome, for instance a disease.
