  1. 1. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : David Håkansson; [2023]
    Keywords : ;

    Abstract : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. READ MORE

  3. 2. Life extension of welded steel details in bridges

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Zhelei Jin; [2023]
    Keywords : Welded joints; Fatigue; Pre-fatigue; Life extension; Fracture mechanics; Finite element analysis; HFMI; ; Svetsade fogar; utmattning; förutmattning; livsförlängning; frakturmekanik; finit elementanalys; HFMI; ;

    Abstract : High-Frequency Mechanical Impacts (HFMI) is a surface treatment technique utilized to introduce residual stresses and extend the service life of structures. This project primarily focuses on studying the life extension effects of HFMI on welded structures that have undergone fatigue and have existing cracks. READ MORE

  4. 3. Development of a System to Quantify Coking in Rocket Nozzle Cooling Channels

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Adam Parks; [2022]
    Keywords : methane; pyrolysis; reusable; carbon deposition; ozone cleaning; rocket engines; cooling channels; borescope; metan; pyrolys; återanvändbar; koldeposition; ozon-rening; raketmotorer; kylkanaler; boreskop;

    Abstract : Liquid methane is becoming an increasingly attractive rocket propellant due to its high performance characteristics and potential to support in-situ resource utilisation. Methane, however, when heated, can thermally decompose in a process known as pyrolysis. READ MORE

  5. 4. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Alejandra Fernandez Castaneda; [2022]
    Keywords : Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Abstract : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  6. 5. Sensors for intelligent and reliable components

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Pontus Lundman; [2020]
    Keywords : Wind turbine; Gearbox; Sensor; Condition monitoring; Cyber-physical system; Vindkraftverk; Växellåda; Sensor; Tillståndsövervakning; Cyberfysiskt system;

    Abstract : One way to tackle the climate change society is facing today is through the change to renewable energy sources, such as wind power. Today, a trend when it comes to technology is that products are evolving into becoming more cyber-physical systems (CPS) by integrating functions realized with mechanics, control and communication.
