  1. 1. Data Augmentations for Improving Vision-Based Damage Detection : in Land Transport Infrastructure

    University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

    Author : Punnawat Siripatthiti; [2023]
    Keywords : Computer Vision; Data Augmentation; Object Detection; Crack Detection; Road Damage Detection; Sleeper Defect Detection; datorseende; dataökning; objektdetektering; sprickdetektering; vägbeläggning; järnvägsslipers;

    Abstract : Crack, a typical term most people know, is a common form of distress or damage in road pavements and railway sleepers. It poses significant challenges to their structural integrity, safety, and longevity. Over the years, researchers have developed various data-driven technologies for image-based crack detection in road and sleeper applications. READ MORE

  3. 2. Extraction of Backfilled Tailings in the Dannemora Mine – Economic Potential and Rock Stability Assessment

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : John Winlund; [2022]
    Keywords : backfilled tailings; Dannemora mine; iron ore; rock stability; stopes; återfylld anrikningssand; Dannemoragruvan; järnmalm; bergstabilitet; öppna brytningsrum;

    Abstract : The cut-off grade determines what rock mass are economic to mine. At the Dannemora mine, in eastern Bergslagen, Sweden, previously processed ore generated tailings (enrichment sand) with an iron content of 21-22 % that was backfilled into large open bodies (stopes) in the mine between 2013-2015.

  4. 3. Simulations of experimental crack development in ceramic material with notched specimen

    University essay from KTH/Hållfasthetslära

    Author : Clas Dahlin; [2022]
    Keywords : Solid Mechanics; Fracture mechanics; Ceramics; Dynamics; Ballistics; Hållfasthetslära; Brottmekanik; Keramer; Dynamik; Ballistik;

    Abstract : Low-density armour often uses ceramic materials, as their high compressive strength and relatively low weight make the material ideal for moving in the field. The ballistic protection works by redirecting the plastic flow of the projectile radially, which reduces penetration. READ MORE

  5. 4. Simulation of Rolling Mill to Computeand Improve Load Distribution

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Pontus Darth; [2021]
    Keywords : Finite Element; Simulation; Hot rolling mill; SSAB; Swerim AB; Roll Spallings; Spallings; Roll Failure;

    Abstract : This master thesis was done at Swerim AB in cooperation with SSAB and the Technical University of Luleå in the purpose of preventing spalling problems in hot rolling mills. Spallings are a fatigue damage that occurs on the rolls due to extreme loads and unfavorable conditions between the rolls in a mill. READ MORE

  6. 5. Development of a method for estimation of contact fatigue life in hypoid gears

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srigiripura Sahana Vittal; [2020]
    Keywords : Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

    Abstract : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. READ MORE
