  1. 16. Diversifierat filmarv : Enskilda arkivinstitutioners arbete med att bevara och tillgängliggöra film

    Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Anna Johansson; [2022]
    Nyckelord :Private Archives; Film Archive; Long-term Preservation; Access; Digital Information; Digitization; Cultural Heritage and Archival Institutions; Enskilda arkiv; Filmarkiv; Bevara; Tillgängliggöra; Digital information; Digitisering; Kulturarv och Arkivinstitutioner;

    Sammanfattning : The aim of this study is to examine how Swedish private archival institutions are working with the long-term preservation and access to their digital film collections. The issue of digital preservation has featured in many studies but fewer of these have concentrated on the challenges of private archives. This is what motivated my study. LÄS MER

  3. 17. Groundwater Inflow into Fractured Rock Tunnels

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Mariam Beydoun; [2022]
    Nyckelord :groundwater inflow; rock tunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynold’s equation; cubic law; grundvatteninflöde; bergtunnel; discrete fracture networks; discrete fracture-matrix; equivalent porous medium; Darcy’s Law; Reynolds equation; cubic law;

    Sammanfattning : Groundwater inflow is a challenge in construction of tunnels in fractured bedrocks since it affects the safety function of tunnels and leads to potential problems in the surrounding environment, such as subsidence, dropdown of the groundwater table. Quantification of groundwater inflow into the tunnel is also important for design of grouting in the construction of the tunnel. LÄS MER

  4. 18. Charge transfer states at polymer solar cell interfaces : Insights from atomic-scale modeling

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Rickard Svensson; [2022]
    Nyckelord :organic solar cells; OSC; polymer; interface; charge transfer; non-fullerene acceptor; PYT; PBDB-T; DFT; TD-DFT; conformation; alkyl groups; methylation; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; exciton binding energy; dipole moment; open-circuit voltage; organiska solceller; OSC; polymer; gränssnitt; laddningsöverföring; icke-fullerenacceptor; PYT; PBDB-T; DFT; TD-DFT; konformation; alkylgrupper; metylering; HOMO; LUMO; FMO; NTO; UV-Vis; DOS; exciton; excitonbindningsenergi; dipolmoment; tomgångsspänning;

    Sammanfattning : Organic solar cells (OSCs) based on non-fullerene acceptors (NFAs) have attracted a great deal of attention in recent years due to their rapidly increasing efficiency and enormous potential. In this work, the optical and electronic properties of systems containing the very promising non-fullerene acceptor PYT have been thoroughly studied with the use of the density functional theory (DFT) and the time-dependent density functional theory (TDDFT).

  5. 19. Proveniensprincipen : En problematiserande undersökning utifrån ett kritiskt arkivteoretiskt perspektiv

    Kandidat-uppsats, Södertörns högskola/Institutionen för historia och samtidsstudier

    Författare :Anna Bergström; [2022]
    Nyckelord :archive; power; the principle of provenance; archivalpower; postmodern; chritical theory; records continuum model; arkiv; makt; proveniensprincipen; arkivmakt; postmodern; kritisk teori; records continuum model;

    Sammanfattning : This paper has had the purpose of examiniating how the chritical discussion about the well known archival theoretical topic The principle of provenance has been discussed by international researchers. The papper has also intended to examinate the discussion of the priniciple of provenance from the swedish national archives guidelines called Överlämnande av arkiv till annan myndighet.

  7. 20. Multiscale mechanical modeling of paperboard

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Gustav Boman; [2022]
    Nyckelord :Paperboard; micromechanics; multiscale; fiber; X-ray; RVE; Technology and Engineering;

    Sammanfattning : This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. LÄS MER
