  1. 1. Sustainable Manufacturing through Material Efficiency Management

    Författare :Sasha Shahbazi; Magnus Wiktorsson; Peter Ball; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Innovation and Design; innovation och design;

    Sammanfattning : Material efficiency contributes to reduced industrial waste volumes, reduced extraction and consumption of virgin raw materials, increased waste segregation, decreased energy demand, and reduced carbon emissions, thereby generally mitigating the environmental impact of the manufacturing industry. However, the area of material efficiency in manufacturing is under-researched, and related knowledge is limited particularly at individual manufacturing sites and lower levels. LÄS MER

  3. 2. Analysis of Ball CV-joints of Fixed Type

    Författare :Peter Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frictional forces; displacements; contact angles; load distribution;

    Sammanfattning : Two theoretical models for analysing ball CV-joints of fixed type are presented. The models, which have been implemented in computer programs, calculate internal conditions such as load distribution, contact angles and displacements for different operating conditions. LÄS MER

  4. 3. Assessment of ceramic raw materials in Uganda for electrical porcelain

    Författare :Peter Wilberforce Olupot; Stefan Jonsson; Thommy Ekström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; porcelain; characterisation; bending strength; dielectric strength; Uganda; Chemical engineering; Kemiteknik;

    Sammanfattning : Clay, quartz and feldspar are widely available in Uganda. The location and properties of various clay deposits are reported in the literature, but little is reported on feldspar and quartz deposits. In this work an extended literature on ceramics and porcelains in particular, is documented. LÄS MER

  5. 4. Included yet Excluded? : Conditions for Inclusive Teaching in Physical Education and Health

    Författare :Peter Åström; Staffan Karp; Simon Wolming; Stefan Lund; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Inclusive teaching; exclusion; physical education and health; motivation; Education; pedagogik;

    Sammanfattning : This dissertation has examined the conditions for teachers who teach Physical Education and Health (PEH) in elementary school (age 11-12) and their opportunities to pursue inclusive teaching with the aim of reaching all pupils. The compilation thesis consists of four different articles and provides knowledge from the perspectives of pupils and teachers, but it also includes teaching and learning processes that were studied in situ.

  7. 5. On complex convexity

    Författare :David Jacquet; Mikael Passare; Peter Pflug; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ℂ-convex; Linearly convex; Charathéodory metric; Kobayshi metric; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Sammanfattning : This thesis is about complex convexity. We compare it with other notions of convexity such as ordinary convexity, linear convexity, hyperconvexity and pseudoconvexity. We also do detailed study about ℂ-convex Hartogs domains, which leads to a definition of ℂ-convex functions of class C1. LÄS MER
