  1. 16. Part Quality Prediction and Variation Reduction in Multistage Machining Processes Based on Skin Model Shapes

    Författare :Filmon Yacob; Daniel Semere; Sophie Gröger; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining simulation; model-based prediction; variation propagation; variation source identification; variation compensation; tolerance analysis; Octree; anomaly detection; quaternion; dual quaternion; Plücker coordinate.; Maskinbearbetningssimulering; modellbaseradförutsägelse; variationsspridning; variationskällidentifiering; variationskompensation; toleransanalys; Octree; dual quaternions; Plücker-koordinat.; Production Engineering; Industriell produktion;

    Sammanfattning : All manufacturing processes inevitably induce variations into manufactured parts that may result in nonconformance. Nonconforming parts incur costs due to the additional process required for rework or scrap loss. Hence, methodical efforts to reduce these variations are necessary for competitive manufacturing.

  3. 17. Determination of Banned Azo Dyes in Leather

    Författare :Lars-Henric Ahlström; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analytisk kemi; Analytical chemistry; extraction; azo dyes; aromatic amines;

    Sammanfattning : Dyes are commercially indispensable and the expanding industry offers a complete palette of colors. Azo dyes constitute the largest chemical class of synthetic dyes because of their versatility, low price, and ease of production. LÄS MER

  4. 18. Tailored Reaction Media for the Synthesis of Subvalent Cluster Compounds

    Författare :Josefin Åkerstedt; Lars Kloo; Sven Lidin; Ulf Gedde; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Inorganic Chemistry;

    Sammanfattning : Different synthetic approaches and modifications to reaction media have been applied in order to find new routes to the synthesis of main-group clusters and transition metal compounds. The focus has been on the Group 15 element bismuth and the transition metal palladium. LÄS MER

  5. 19. Större våld än nöden kräver? : Medievåldsdebatten i Sverige 1980-1995

    Författare :Ulf Dalquist; Sociologi; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TV; video; social problems; media effects; media effects research; social constructivism; moral panic; claims-making; censorship; Press and communication sciences; rhetorics; Media violence; film; Journalistik; media; kommunikation;

    Sammanfattning : This study is an attempt to analyze the social construction of media violence in the Swedish press debate 1980-1995. Altogether, 1029 articles from seven of Sweden's biggest daily and evening papers were qualitatively analyzed. Numerous claims refer to scientific 'proof' that media violence breeds personal aggression. LÄS MER

  7. 20. Molecular, micro- and ultrastructural investigations of labile tissues in deep time

    Författare :Johan Gren; Berggrundsgeologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; eumelanin; fossils; histology; integument; IR microspectroscopy; melanin; melanosomes; molecular palaeontology; ToF-SIMS; XAS;

    Sammanfattning : This thesis comprises investigations of microstructures and molecular remains, preserved in a variety of fossil specimens. The results are presented in six papers, collectively aiming to thoroughly examine fossil traces of such remains by employing a combination of both established and relatively new analytical methods.
