  1. 1. IMAGINE THAT – DATORREKLAM SOM UTTRYCK FÖR SAMTIDA SAMHÄLLSIDEAL. En multimodal kritisk diskursanalys av 1980-talets reklambilder för persondatorer

    Kandidat-uppsats, Göteborgs universitet/Institutionen för journalistik, medier och kommunikation

    Författare :Esther Malmqvist; [2024-03-06]
    Nyckelord :Persondator; Marknadsföring; Medieteknologier; Sociotechnical Imaginaries; Multimodal kritisk diskursanalys;

    Sammanfattning : Until the 1970s, computers were primarily being used by universities, bigger companies or nationstates. With the invention of the microchip the average size of computers was reduced and they became more affordable, resulting in the creation of the microcomputer and eventually personal computers.

  3. 2. Optical Communication using Nanowires and Molecular Memory Systems

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Thomas Kjellberg Jensen; [2024]
    Nyckelord :neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Sammanfattning : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

  4. 3. Kan man lära gamla hundar att sitta? : En kvalitativ intervjustudie om fyra äldre människors användning av digitala skärmar

    Kandidat-uppsats, Umeå universitet/Institutionen för kultur- och medievetenskaper

    Författare :Sofia Aspholm; [2024]
    Nyckelord :media-usage; elderly; uses and gratifications; affordances and constraints; adoption categories; digital screens.;

    Sammanfattning : The focus of this thesis is on how elderly people make use of digital screens. The study studies how these elderly individuals view their screen time and it highlights how they have adapted to an ever-changing media landscape. LÄS MER

  5. 4. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  7. 5. Structural analysis of HZO thin film and electrode using X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER
