  1. 1. Development of Fluidity Measurement Technique and Automation of Measurement Station : Developing the existing Fluidity Measurement Station by automating the operation and measuring the fluidity digitally with MATLAB Image Processing Tools.

    Master-uppsats, Högskolan i Jönköping/JTH, Konstruktion och produktutveckling

    Författare :Pratheek Ullal; [2019]
    Nyckelord :Product Development; Fluidity; Casting; MATLAB Image Processing Tool.;

    Sammanfattning : Bryne AB has invented a device called Loop for measuring the fluidity of molten metal. Loop is made up of refractory fiber material and has a dimension of 196 sq.mm within which there is an engraved spiral shaped runway for the molten metal to flow. LÄS MER

  2. 2. Direct multispectral photogrammetry for UAV-based snow depth measurements

    Master-uppsats, KTH/Geoinformatik

    Författare :Kathrin Maier; [2019]
    Nyckelord :Unmanned Aerial Vehicles UAV ; snow depth; direct photogrammetry; multispectral imagery; cryosphere;

    Sammanfattning : Due to the changing climate and inherent atypically occurring meteorological events in the Arctic regions, more accurate snow quality predictions are needed in order to support the Sámi reindeer herding communities in northern Sweden that struggle to adapt to the rapidly changing Arctic climate. Spatial snow depth distribution is a crucial parameter not only to assess snow quality but also for multiple environmental research and social land use purposes. LÄS MER

  3. 3. Statisk deformationsmätning med fotobaserad skanning : Utförd med icke-professionella digitalkameror

    Kandidat-uppsats, Högskolan i Gävle/Samhällsbyggnad; Högskolan i Gävle/Samhällsbyggnad

    Författare :Anna Jonsson; Pernilla Eriksson; [2019]
    Nyckelord :close-range photogrammetry; static deformation measurements; digital camera; smartphone camera; Fotobaserad skanning; statisk deformationsmätning; digitalkamera; smartphonekamera;

    Sammanfattning : Till följd av den utveckling som skett hos digitalkameror och programvaror för bildbehandling de senaste åren har intresset för fotobaserad skanning (FBS) vuxit. I denna studie utvärderades FBS som ett alternativ till terrester laserskanning (TLS) för statisk deformationsmätning och relaterade till kavitationsskador på vattenturbinkolvar där volym och maxdjup mäts.

  5. 5. Statistical Approach for the Design of Refresh-Free eDRAM with Retention Timing Constraint

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Arturo Prieto; [2019]
    Nyckelord :Memory; eDRAM; DRAM; SRAM; IC; Refresh; Statistics; Importance Sampling; Monte Carlo; Technology and Engineering;

    Sammanfattning : In digital integrated circuits, memories are often a limiter for main performance, power and area. Over the past decade, integrated memories have gained dominance in terms of area and power cost. In applications like machine learning or image processing the area share can be above 80% consuming more than 50% of the total power budget. LÄS MER
