  1. 6. JOINING SEQUENCE ANALYSIS AND OPTIMIZATION FOR IMPROVED GEOMETRICAL QUALITY

    Författare :Roham Sadeghi Tabar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Efficiency; Optimization; Sequencing; Geometrical Quality; Non-Rigid Variation Simulation; Joining;

    Sammanfattning : Disturbances in the manufacturing and assembly processes cause geometrical variation from the ideal geometry. This variation eventually results in functional and aesthetic problems in the final product. Being able to control the disturbances is the desire of the manufacturing industry. LÄS MER

  3. 7. Mathematics textbooks for teaching : An analysis of content knowledge and pedagogical content knowledge concerning algebra in Swedish upper secondary education

    Författare :Wang Wei Sönnerhed; Berner Lindström; Jonas Emanuelsson; Ingemar Holgersson; Göteborgs universitet kommunikation och lärande Institutionen för pedagogik; []
    Nyckelord :mathematics textbooks; school algebra; solving methods; factorization; solving quadratic equations; mathematics teaching; content knowledge; pedagogical content knowledge; geometrical models; algebra history; embedded teaching trajectories;

    Sammanfattning : In school algebra, using different methods including factorization to solve quadratic equations is one common teaching and learning topic at upper secondary school level. This study is about analyzing the algebra content related to solving quadratic equations and the method of factorization as presented in Swedish mathematics textbooks with subject matter content knowledge (CK) and pedagogical content knowledge (PCK) as analytical tools.

  4. 8. Credit risk and forward price models

    Författare :Raquel M Gaspar; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis consists of three distinct parts. Part I introduces the basic concepts and the notion of general quadratic term structures (GQTS) essential in some of the following chapters. Part II focuses on credit risk models and Part III studies forward price term structure models using both the classical and the geometrical approach. LÄS MER

  5. 9. Visualizing the Effects of Geometrical Variation on Perceived Quality in Early Phases

    Författare :Ola S Wagersten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometrical variation; geometry assurance; non-rigid; product development; tolerance analysis; variation simulation; visualization and evaluation.; perceived quality;

    Sammanfattning : In a perfect world, geometrical variation in a manufacturing process would not exist. Every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER

  7. 10. Towards Efficient Evaluation of Impacts of Geometrical Variation on Perceived Quality in Early Phases

    Författare :Ola S Wagersten; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Perceived Quality; variation simulation; visualization and evaluation; Geometrical variation; geometry assurance; non-rigid; tolerance analysis; product development;

    Sammanfattning : In a perfect world, manufacturing would lead to components without geometrical variation. This would mean that every component produced in a series would have the exact same dimensions and, when observed by a trained eye, look exactly identical. However, the world is not perfect and neither are manufacturing processes. LÄS MER
