  1. 1. Digital (o)jämlikhet? IKT-användning i skolan och elevers tekniska kapital

    Författare :Ulli Samuelsson; Claes Nilholm; Tobias Olsson; Patrik Hernwall; Martin Stigmar; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital inequality; digital inclusion; digital divide; technological capital; digital competence; equality in education; compulsory education; secondary education; Digital ojämlikhet; digital inkludering; digitala klyftor; tekniskt kapital; digital kompetens; likvärdig utbildning; grundskola; gymnasieskola;

    Sammanfattning : Avhandlingen handlar om digital (o)jämlikhet. Begreppet (o)jämlikhet utgår från en sammanskrivning av jämlikhet och ojämlikhet men uttalas som det sistnämnda. Problematiken kring digital (o)jämlikhet belyses i avhandlingen i form av fyra olika delstudier samt en kappa. LÄS MER

  7. 5. Energy-Efficient Digital Signal Processing for Fiber-Optic Communication Systems

    Författare :Christoffer Fougstedt; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Digital Signal Processing; Forward Error Correction; Fiber Optic Communication; Application Specific Integrated Circuits; Communication Systems; Non-linear Impairment Mitigation;

    Sammanfattning : Modern fiber-optic communication systems rely on complex digital signal processing (DSP) and forward error correction (FEC), which contribute to a significant amount of the over-all link power dissipation. Bandwidth demands are evergrowing and circuit technology scaling will due to fundamental reasons come to an end; energy-efficient design of DSP is thus necessary both from a sustainability perspective and a technical perspective.
