  1. 1. Linear models for multiscale materials simulations : Towards a seamless linking of electronic and atomistic models for complex metal oxides

    Författare :Akshay Krishna Ammothum Kandy; Peter Broqvist; Jolla Kullgren; Eddie Wadbro; Ben Hourahine; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Force fields; Electronic structure calculations; CCS; DFTB; CCS Q; repulsive fitting; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : Multiscale modelling approaches, connecting data from electronic structure calculations all the way towards engineering continuum models, have become an important ingredient in modern materials science. Materials modelling in a broader sense is already amply used to address complex chemical problems in academic science, but also in many industrial sectors. LÄS MER

  2. 2. Let's Make a Digital Patchwork : Designing for Childrens Creative Play with Programming Materials

    Författare :Ylva Fernaeus; Carl Gustav Jansson; Kristina Höök; Jakob Tholander; Paul Dourish; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; children s programming; interaction design; tangible interaction; human-computer interaction; tangible programming; Computer and systems science; Data- och systemvetenskap; Man-Machine-Interaction MMI ; människa-maskin-interaktion MMI ;

    Sammanfattning : This thesis explores new approaches to making and playing with programming materials, especially the forms provided with screen-based digital media. Designing with these media expressions can be very attractive to children, but they are usually not made available to them in the same degree as are physical materials. LÄS MER

  3. 3. Parallelism in Constraint Programming

    Författare :Carl Christian Rolf; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Parallelism; Constraint Programming; Parallel Consistency; Parallel Search; Distributed Constraint Programming;

    Sammanfattning : Writing efficient parallel programs is the biggest challenge of the software industry for the foreseeable future. We are currently in a time when parallel computers are the norm, not the exception. Soon, parallel processors will be standard even in cell phones. LÄS MER

  4. 4. Seeing the parts, understanding the whole : A technology education perspective on teaching and learning in processes of analysing and designing programmed technological solutions

    Författare :Anne-Marie Cederqvist; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; technology education; programmin; programmed technological solutions; programming materials; phenomenography; LeaDS - Learning in a Digitalised Society; LeaDS - Lärande i ett digitalt samhälle; technology education; programming; programmed technological solutions; programming materials; phenomenography;

    Sammanfattning : Analysing and designing Programmed Technological Solutions (PTS) has been introduced as a part of technology education in an effort to bring elements of programming into the curriculum for compulsory school, in order to develop pupils’ understanding of how PTS work and are controlled by programming. However, what an appropriate understanding entails at this level remains to be articulated, particularly how this understanding looks from a pupil’s perspective. LÄS MER

  5. 5. Simulation of Phase Transformations and coarsening : Computational tools for alloy development

    Författare :Johan Jeppsson; John Ågren; Gerhard Inden; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. LÄS MER
