  1. 1. Few-Shot Learning for Quality Inspection

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Jesper Palmér; Ahmad Alsalehy; [2023]
    Keywords : Few-Shot Learning; AI; Transformers; ViT Deviation; Vision Transformers;

    Abstract : The goal of this project is to find a suitable Few-Shot Learning (FSL) model that can be used in a fault detection system for use in an industrial setting. A dataset of Printed Circuit Board (PCB) images has been created to train different FSL models. READ MORE

  3. 2. Improved Furnace Control : System identification and model predicative control of Outokumpu’s reheating furnace

    University essay from Uppsala universitet/Signaler och system

    Author : Oscar Holmqvist; [2023]
    Keywords : Systeem Identification; Model Predictive Control;

    Abstract : This thesis investigates one option for improving the control of a reheating furnace used in heating steel slabs before hot rolling; an essential part of the steel manufacturing process. The furnace consumes a significant amount of energy, leading to high cost and high carbon dioxide emissions. READ MORE

  4. 3. 3D Coating of Interface Materials for High-Performance RF Passive Devices

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Xiner Shen; [2023]
    Keywords : Ceramic coating; Dip coating; Radio frequency; Passive RF devices; Quality factor; Keramisk beläggning; Dip-beläggning; Radiofrekvens; Passiva RF-enheter; Kvalitetsfaktor;

    Abstract : The demand for high-performance Radio Frequency (RF) passive devices has been steadily increasing due to the growing complexity and sophistication of wireless communication systems. The Quality factor (Q-factor) is a key parameter for describing the signal losses and the energy efficiency of resonators. READ MORE

  5. 4. Defect classification in LPBF images using semi-supervised learning

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Anton Göransson; [2022]
    Keywords : Additive manufacturing; Laser powder bed fusion; Machine learning; Siamese neural networks; Deep learning; Defect classification;

    Abstract : Laser powder bed fusion is an additive manufacturing technique that is capable of building metallic parts by spreading many layers of metal powder over a build surface and using a laser to melt specific sections of the surface. The part is built by melting consecutive layers on top of each other until the design is completed. READ MORE

  6. 5. The Influence of Drawing Speed on Steel Wire Surface Quality

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Felicia Viklund; Amanda Lundin Bornström; [2022]
    Keywords : carbon steel; wire drawing; drawing speed; surface roughness; defects; kolstål; tråddragning; draghastighet; ytjämnhet; defekt;

    Abstract : Tråddragning är en kallbearbetningsprocess där tråd dras genom en dragsten, som plastiskt deformerar materialet och reducerar tvärsnittsarean. En viktig parameter i tråddragningsprocessen är draghastigheten - en ökad draghastighet kan förbättra produktiviteten, vilket är önskvärt för företaget Suzuki Garphyttan AB då efterfrågan på produkter har ökat.
