  1. 1. Developing a Test Method to Evaluate the Blackout Effect of Uncoated Curtains at Varying Angles

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Sara Muminovic; Christina Lindén; [2023]
    Nyckelord :Blackout effect; blackout curtain; uncoated woven curtains; angle interval; light transmission; light box; light diffuser; microscopic image analysis;

    Sammanfattning : This study aimed to explore the integration of varying angles in small-scale measurements and assess the light transmission performance of uncoated curtains. A total of four curtains were evaluated: blackout curtain samples 1 and 2 had a weft satin structure, while daytime curtain samples 3 and 4 consisted of a twill structure. LÄS MER

  3. 2. A Methodology for Evaluating the Performance of Material Models Under Biaxial Loads

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

    Författare :Emmie Salomonsson; Ina Ögren; [2023]
    Nyckelord :Material Model; Biaxial Test; Punch Test; Material Test; POM; Simulation; FEA.; Technology and Engineering;

    Sammanfattning : The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. LÄS MER

  4. 3. Multiclass Brain Tumour Tissue Classification on Histopathology Images Using Vision Transformers

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Christoforos Spyretos; [2023]
    Nyckelord :medical imaging; deep learning; classification; CNN; Vision Transformer; glioblastoma; GBM; IvyGAP; brain tumour; histopathology; digital pathology; histology;

    Sammanfattning : Histopathology refers to inspecting and analysing tissue samples under a microscope to identify and examine signs of diseases. The manual investigation procedure of histology slides by pathologists is time-consuming and susceptible to misconceptions. LÄS MER

  5. 4. Bedömning av prediktiv förmåga för Finita Elementberäkningar med optisk töjningsmätning (DIC)

    Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Albin Zetterqvist; Linus Hjelm; [2023]
    Nyckelord :Digital image correlation; Finite element; Predictive capability; Model calibration; FEM; DIC; Modellkalibrering;

    Sammanfattning : The goal of this thesis is to improve the predictive capability of Finite element (FE) by gathering data from experimental test and implement the characteristics into the material model that is used. FE is a commonly used method to predict the mechanical behavior of materials and components during applied forces. LÄS MER

  7. 5. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

    Författare :Amir Saeidi; Olafur Johannsson; [2023]
    Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER
