  1. 1. Process parameter optimisation for Waspaloy using Laser-Directed Energy Deposition with Powder

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Johannes Lövhall; [2024]
    Keywords : Process parameter optimisation; Waspaloy; Laser-Directed Energy Deposition with Powder;

    Abstract : Material utilisation is of importance in the manufacturing industry formaking the most of each material, minimising waste and increasing cost-effectiveness. In this thesis, samples of Waspaloy built with the method of L-DED-P has been analysed in order to investigate how process pa-rameters influence the build quality and geometrical accuracy in as-builtobjects.

  2. 2. Comparing Static and Dynamic Synchronization of GUI-based tests: An Industrial study

    University essay from Blekinge Tekniska Högskola/Institutionen för programvaruteknik

    Author : Carl Johan Wellner; [2024]
    Keywords : GUI testing; Synchronization; Test automation; Playwright; Selenium;

    Abstract : Background. Speed is getting more and more critical in modern Software Engineering to be able to respond to users’ expectations of product development. One practice that takes a significant amount of time in the process of releasing software to the customers is testing. READ MORE

  3. 3. Machine-vision-based Detection of Paper Roll Core Eccentricity : Fast and Robust On-Line Measurement Using Circular Hough Transform

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Erik Sehlstedt; [2022]
    Keywords : Eccentricity; Core eccentricity; Paper roll; Machine vision; Computer vision; Hough transform; Circular Hough transform; Defect detection; On-line measurement; Quality control;

    Abstract : The field of computer vision offers tools that allow machines to derive meaningful infor-mation from video and images and consequently make decisions based on visual inputs. In the paper industry, implementation of machine vision (MV) can be used to automate and speed up processes that require visual inspection, particularly certain segments of quality control – one such application being detection and measurement of paper roll core eccentricity.

  4. 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

  5. 5. Predictive maintenance using NLP and clustering support messages

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Ugur Yilmaz; [2022]
    Keywords : Predictive maintenance; support messages; NLP; unsupervised clustering; intent recognition; LDA; UMAP; HDBSCAN; BERT; Swedish BERT KB-BERT ; Billogram;

    Abstract : Communication with customers is a major part of customer experience as well as a great source of data mining. More businesses are engaging with consumers via text messages. Before 2020, 39% of businesses already use some form of text messaging to communicate with their consumers. Many more were expected to adopt the technology after 2020[1]. READ MORE
