1. 1. Mining infrequent group of motifs from multidimensional time series: A case study at Alfa Laval AB

   University essay from Högskolan i Halmstad/Akademin för informationsteknologi

   Author : Fabeena Thoufeeq; Reeba Susan Ashok; [2024]
   Keywords : ;

   Abstract : In collaboration with an industrial partner, Alfa Laval AB, this thesis discusses a novel approach for identifying operational modes, specifically a cleaning mode, in separator machines without the benefit of labelled data and with very limited operating knowledge. Understanding the operational modes is crucial for comprehending the machine’s behaviour and ensuring its optimal performance. READ MORE

3. 2. Diving Deep: Seabird foraging tactics and local prey field

   University essay from SLU/Dept. Of Aquatic Resources

   Author : Elin Andersson Sjöholm; [2024]
   Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

   Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

4. 3. Measuring copper abundances in the Galactic Bulge

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Nikolei Höglinger; [2024]
   Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

   Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

5. 4. Behaviours of older adults in urban outdoor environments during warm days

   University essay from Göteborgs universitet/Institutionen för geovetenskaper

   Author : Sandra Lujic; [2023-08-18]
   Keywords : Older adults; urban outdoor environments; behaviour; preferences; thermal comfort;

   Abstract : As a result of climate change, heat waves are expected to increase in frequency, duration, and severity, which is particularly threatening to the urban population. Vulnerable groups, including the older population, are more likely to be affected by adverse health effects due to heat exposure. READ MORE

6. 5. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

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

   Author : Ahsan Ali; [2023]
   Keywords : High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Abstract : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.
