  1. 6. The human-computer interface in commercial systems : Investigations of dialogue design factors and usability with alphanumeric display terminals

    Författare :Bengt Johnsson; Bertil Andersson; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; administrative process; administrative system; commercial system; controlled experimentation; criteria; design property; display terminal; field investigation; human-computer interface; man-computer dialogue; man-machine matching; terminal user; usability; Information Systems; Informatik;

    Sammanfattning : When terminal based computer systems are incorporated in administrative processes, man-computer interface technology for many reasons becomes a crucial problem area. Terminal users ("terminalists") in such systems account for a vast number of terminal hours. LÄS MER

  3. 7. Actors at the interface between socio-technical and ecological systems: Analytical starting point for identifying mitigation possibilities in the case of on-site sewage systems

    Författare :Are Wallin; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; interface-actors; Eutrophication; problem-structuring approach; wastewater treatment systems; homeowners;

    Sammanfattning : The thesis addresses several issues related to factors influencing actors around environmental problems to decrease the environmental pressures. Systems treating sewage at the scale of one to a few households (on-site sewage systems, OSSs) comprise a Swedish case study. LÄS MER

  4. 8. Flow and Friction : On the Tactical Potential of Interfacing with Glitch Art

    Författare :Vendela Grundell; Anna Dahlgren; Mårten Snickare; Max Liljefors; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Glitch; Contemporary Art; Photography; Digital Media; Interface; Internet; Systems Aesthetics; Network Society; Tactics; Phenomenology; Spectatorship; Viewer; Experience; Rosa Menkman; Phillip Stearns; Evan Meaney; konstvetenskap; Art History;

    Sammanfattning : This thesis aims to analyze how interfacing affects viewer experiences and viewer positions, and how glitch art online makes that effect visible. Glitch art is concerned with disruptions in the systems that govern how for instance photography is produced, circulated and displayed in a digital image flow. LÄS MER

  5. 9. Analysis, Control, and Design Optimization of Engineering Mechanics Systems

    Författare :Esubalewe Lakie Yedeg; Martin Berggren; Eddie Wadbro; Anton Evgrafov; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Topology optimization; Helmholtz equation; acoustic impedance; anisotropic filter; thin structures; finite element method; Nitsche-type method; interface problem; Optimal control; adjoint method; business data processing; administrativ databehandling;

    Sammanfattning : This thesis considers applications of gradient-based optimization algorithms to the design and control of some mechanics systems. The material distribution approach to topology optimization is applied to design two different acoustic devices, a reactive muffler and an acoustic horn, and optimization is used to control a ball pitching robot.

  7. 10. Cut isogeometric methods on trimmed multipatch surfaces

    Författare :Tobias Jonsson; Mats G. Larson; Karl Larsson; Johan Hoffman; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cut finite element method; isogeometric analysis; Nitsche s method; a priori error estimation; parametric geometry; interface problem; surface CAD;

    Sammanfattning : Partial differential equations (PDE) on surfaces appear in a variety of applications, such as image processing, modeling of lubrication, fluid flows, diffusion, and transport of surfactants.  In some applications, surfaces are drawn and modeled by using CAD software, giving a very precise patchwise parametric description of the surface.
