1. 1. Mutual Enhancement of Environment Recognition and Semantic Segmentation in Indoor Environment

   Master-uppsats,

   Författare :Venkata Vamsi Challa; [2024]
   Nyckelord :Semantic Segmentation; Scene Classification; Environment Recognition; Machine Learning; Deep Learning; Image Classification; Vision Transformers; SAM Segment Anything Model ; Image Segmentation; Contour-aware semantic segmentation;

   Sammanfattning : Background:The dynamic field of computer vision and artificial intelligence has continually evolved, pushing the boundaries in areas like semantic segmentation andenvironmental recognition, pivotal for indoor scene analysis. This research investigates the integration of these two technologies, examining their synergy and implicayions for enhancing indoor scene understanding. LÄS MER

3. 2. Cleaning methods for removal of bound soiling on leather

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Olivia Cati Starck; [2023-11-14]
   Nyckelord :Conservation; Leather; Cleaning; Vulpex; White spirit; Isopropanol; Gellan gum gel;

   Sammanfattning : This thesis investigates the removal of bound soiling on leather using three cleaning methods: Vulpex (10%) in white spirit, gellan gum gel loaded in isopropanol and white spirit by itself. More detailed studies of cleaning methods for bound soiling in leather conservation are sparse. LÄS MER

4. 3. Nya metoder för fernissaborttagning – En komparativ studie

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Alica Larsson; [2023-11-08]
   Nyckelord :Oil painting; Varnish removal; Evolon® CR; Tissue-gel composite;

   Sammanfattning : In recent years, new varnish removal methods have emerged in conservation, with two notable approaches: the tissue-gel composite method, involving gel-coated tissue material pressed onto varnished surfaces for simultaneous dissolution and binding, and the use of Evolon® CR textile saturated with solvent. Evolon® CR offers an alternative to gels and tissue-gel composites, aiming to eliminate residue from gel thickening agents and the need for mechanical cleaning, while enabling the use of non-polar solvents in a bound form.

5. 4. Bläckborttagning från ben med hjälp av geler En kvantitativ studie för bläckborttagning på björnbäcken och björnkranium från Naturhistoriska riksmuseet

   Kandidat-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Engla Nordin; [2023-11-07]
   Nyckelord :Conservation; reversibility; bones; FTIR; nanogels; hydrogels; ink.;

   Sammanfattning : This bachelor's thesis has investigated four different hydrogels loaded in different solvents efficiency to remove unknown ink from four pelvic bones and one skull from five bear individuals that belongs to The Swedish Museum of Natural History. The experimental part of the thesis consists of an FTIR analysis together with microscopy and macroscopy analysis of the ink on the bear skeletons, as well as some tests of different gel-solvent combinations on a moose skull.

7. 5. A PILOT STUDY ON STAIN REDUCTION Effects of Stains, Cleaning Agents, and Cleaning Methods on Polyester Textiles

   Master-uppsats, Göteborgs universitet/Institutionen för kulturvård

   Författare :Karin Hindborg; [2023-08-28]
   Nyckelord :colour measurements; spot cleaning; suction table; tensile testing; textile con-servation;

   Sammanfattning : The thesis was an experimental pilot study that investigated efficiency and effects of stains and cleaning agents on polyester textiles. A literature review and interviews with textile conservators were used to understand the degradation of polyester fibres and to find suit-able staining and cleaning agents to use in the experiments of the study.
