  1. 1. 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.

  3. 2. On intermittency in the turbulent asymptotic suction boundary layer

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Edoardo Foschi; [2023]
    Nyckelord :Turbulence; turbulent boundary layer; intermittency; numerical simulation; DNS; tripping; suction;

    Sammanfattning : This thesis presents a series of direct numerical simulations (DNS) performed in order to understand the discrepancy in the literature regarding turbulent asymptotic suction boundary layers (TASBLs) at low Reynolds numbers. The hypothesis to be tested is that the main reason for higher turbulence intensities observed in experiments compared to DNS is that the latter exhibits intermittent patches of laminar flow, developing both temporally and spatially.

  4. 3. Effect of Refining on Softwood Pulp with Addition of Eucalyptus for Greaseproof Paper Production : Vacuum Dewatering in Laboratory Scale

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Anton Nordling; [2023]
    Nyckelord :Refining; beating; eucalyptus; greaseproof paper; degree of refining; vacuum dewatering; formation; air permeance; Malning; Eukalyptus; fettresistent papper; malgrad; vakuumavvattning; formation; luftpermeans;

    Sammanfattning : We are provided countless products from the forest industry and has been through many years. Paper, paper board, packaging materials and furniture to mention a few. A special type of paper used in food packaging for example, is greaseproof paper. LÄS MER

  5. 4. Robot arm with object detection for waste management

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Albin Gunnarsson; Dag Ehlin; [2023]
    Nyckelord :Mechatronics; Raspberry Pi; stepper motors; cylindrical robot arm; machine learning;

    Sammanfattning : Recycling is becoming more crucial due to the fast pace of consumerism. This thesis explores how well a robot arm, with three degrees of freedom, can be implemented to give an autonomous recycling process. After the prototyping phase it was found that a cylindrical robot arm was best suited for the project. LÄS MER

  7. 5. Dimensioning study of EPR2 fuel pool cooling system

    Master-uppsats, KTH/Fysik

    Författare :Thomas Rubler; [2023]
    Nyckelord :EPR2; PTR; spent fuel pool; heat exchange; EPR2; PTR; bassäng för utbränt kärnbränsle; värmeväxling.;

    Sammanfattning : The PTR system allows the EPR2 fuel pool to be cooled. The evacuation of the residual power fromthe pool is ensured by several heat exchangers and pumps, which have to be dimensioned in order to meetdifferent requirements.In order to dimension them, the worst-case scenario of the components must first be determined.
