1. Experimental and computational analysis of the thermal degradation and the loss of strength of engineered wood-based panels
University essay from Lunds universitet/Avdelningen för BrandteknikAbstract : The current trends in the construction industry push toward materials that are more sustainable and environmentally friendlier than more traditional building materials such as concrete and steel. Timber and timber composites are one of the most popular materials on this list, due to both their mechanical strength and pleasant aesthetics. READ MORE

2. Improving Availability of the Pelletization Process
University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleAbstract : The Grate-Kiln-Cooler process is a commonly used method of sintering during iron ore pelletization, where the pellets are formed, dried, and hardened. The pellets are oxidized in the rotating Kiln, turning magnetite (Fe3O4) to hematite (Fe2O3), making the pellets attain suitable metallurgical attributes for further processing. READ MORE

3. Automatic Crack Detection in Sand Molds Using Image Processing and Convolutional Neural Networks
University essay from Uppsala universitet/Signaler och systemAbstract : Sand casting is used to manufacture large metal workpieces. The processing is executed by pouring molten metal into a sand mold. During the process, the mold is subjected to mechanical and thermal stress. It is of economic interest to inspect the molds for defects that can affect casting results, in the worst case leading to discarded products. READ MORE

4. Energy and Strength-based Criteria for Intralaminar Crack Growth in Regions with High Stress Gradients
University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematikAbstract : Cross-ply composite laminates can develop very high density of transverse cracks in the 90-layer under severe thermal and mechanical loading conditions. At such high crack densities, two adjacent cracks start to interact, and a stress gradient is created in the region between these cracks. READ MORE

5. Structural modifications of polyester fibres induced by thermal and chemical treatments to obtain high-performance fibres
University essay from KTH/Fiber- och polymerteknologiAbstract : Del A: Polyetylentereftalat fibrer I detta arbete presenteras olika metoder för att framställa monofilament av polyetylentereftalat (PET) (diameter: 30-50 µm) med en radiell gradient. Nyutvecklad Raman-spektroskopiteknik har använts för att kartlägga dessa inducerade radiella gradienter i t.ex. kristallinitet. READ MORE
