  2. 1. Design of flexible lattice structures : a design for additive manufacturing perspective

    Author : Satabdee Dash; Innovation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design for additive manufacturing; DfAM; Lattice structures; Flexibility; Compuational methods; Numerical modelling; Engineering design process;

    Abstract : Recent years has seen an unprecedented growth in emerging technologies like Additive manufacturing (AM), augmenting the manufacturing capabilities through a multitude of opportunities while also introducing unique constraints, such as support structures, and post-processing requirements. Taking full advantage of the potential of AM demands product designs to be optimised for both opportunities and constraints specific to AM, requiring evolution from the traditional design for manufacturing to design for additive manufacturing (DfAM).

  4. 2. Flexibility in knowing school mathematics : In the contexts of a Swedish and an Indian school class

    Author : Ingrid Dash; Pedagogik; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics education; compulsory school; Sweden; Orissa; India; flexibility in knowing; modes of knowing; authorship; agency; phenomenography; contextual analysis; intercultural perspective;

    Abstract : A central question in mathematics education research concerns understanding. The main objective of the present thesis has been to obtain insights into flexible modes of knowing in school mathematics in two school class contexts, and how these relate to modes of being a learner in these contexts, with specific focus on learners’ flexible ways of discerning parts and delimiting wholes, and how they understand part- and whole-relationships while doing mathematics.

  5. 3. Nonlinear Numerical Simulations of Interactions Between Ice Rubble and Structure

    Author : Aniket Patil; Andrzej Cwirzen; Björnar Sand; Lennart Fransson; Knut Vilhelm Høyland; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ice mechanics; ice rubble; sea ice ridges; punch through test; shear box test; friction coefficient; cohesive element method; smoothed particle hydrodynamics; continuous surface cap model; numerical modelling; Byggkonstruktion; Structural Engineering;

    Abstract : This research is focused on three distinct but interconnecting topics:1) investigation of physical and mechanical properties of ice rubble, 2) material modelling of ice rubble, 3) numerical simulation of the interaction between ice rubble structure interaction. large scatter in the values of physical and mechanical properties of ice rubble can be seen in the literature due to non-standardised methods.

  6. 4. Microfluidic bead-based methods for DNA analysis

    Author : Aman Russom; Ulf Gyllensten; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; single nucleotide polymorphism; DNA analysis; SNP; microfluidics; pyrosequencing; beads; lab on a chip; hybridization; DASH; microsystem; micro totat analysis system; allele-specific extension; DASH; microcontact printing; Genetik; Clinical genetics; Klinisk genetik;

    Abstract : With the completion of the human genome sequencing project, attention is currently shifting toward understanding how genetic variation, such as single nucleotide polymorphism (SNP), leads to disease. To identify, understand, and control biological mechanisms of living organisms, the enormous amounts of accumulated sequence information must be coupled to faster, cheaper, and more powerful technologies for DNA, RNA, and protein analysis.
