  2. 1. Makers, Materials and Machines : Understanding Experience and Situated Embodied Practice in the Makerspace

    Author : Sophie Landwehr Sydow; Jakob Tholander; Martin Jonsson; Maria Normark; Alexandra Weilenmann; Södertörns högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HCI; making; materials; machines; experience; makerspace; situated practice; embodied interaction; material interaction; maker culture; material turn; digital fabrication; material literacy; machine sensibility; pliable machine; Östersjö- och Östeuropaforskning; Baltic and East European studies; informationssamhället;

    Abstract : This thesis explores interaction between humans, materials, and machines, in the context of makerspaces. The concept of making describes a practice that deals with new technologies in combination with craft to create artifacts in physical, digital and hybrid forms. READ MORE

  4. 2. Iron Losses in Electrical Machines - Influence of Material Properties, Manufacturing Processes, and Inverter Operation

    Author : Andreas Krings; Juliette Soulard; Oskar Wallmark; Annette Mütze; KTH; []

  6. 4. Ghosts and machines : regularized variational methods for interactive simulations of multibodies with dry frictional contacts

    Author : Claude Lacoursière; Bo Kåggström; Ander Klarbring; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Discrete mechanics; Variational method; Contact problems; Impacts; Least action principle; Saddle point problems; Lagrange Multipliers; Constrained systems; Multibody Systems; Numerical regularization; Constraint realization; Constraint stabilization; Dry friction; Differential Algebraic Equations; Nonsmooth problems; Linear Complementarity; Quaternion algebra; Numerical linear algebra; Physics modeling; Interactive simulation; Numerical stability; Rigid body dynamics; Dissipative systems; Computational physics; Beräkningsfysik;

    Abstract : A time-discrete formulation of the variational principle of mechanics is used to provide a consistent theoretical framework for the construction and analysis of low order integration methods. These are applied to mechanical systems subject to mixed constraints and dry frictional contacts and impacts---machines. READ MORE

  7. 5. Making Magic Machines

    Author : Kristina Andersen; Kristina Höök; Mark Blythe; Steve Benford; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Människa-datorinteraktion; Human-computer Interaction;

    Abstract : How can we design experiences that explore ideas and notions of the unknown? The aim of the work outlined here is to create short, intense, workshop-like experiences that generate strong commitments, and expose underlying personal desires as drivers for new ideas. I would like to propose a material practice, which uses open-ended making to engage in the imagination of new things. READ MORE
