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.

3. 2. Optical Communication using Nanowires and Molecular Memory Systems

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

   Author : Thomas Kjellberg Jensen; [2024]
   Keywords : neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

   Abstract : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

4. 3. Geomorphic change along the Rönne river : Effects caused by dams

   University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Author : Adam Scheér; [2024]
   Keywords : fluvial morphology; dams; GIS; Rönne river;

   Abstract : Many rivers can shape their path through the landscape with erosion and deposition where the riverbed and riverbanks both shape the direction and energy of the flow. The river flow can erode the riverbanks and create meanders which is when the river creates bends in its path that become increasingly curved. READ MORE

5. 4. A study on the effects of mercury in the environment: A focus on atmospheric contributions

   University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap; Göteborgs universitet / Institutionen för biologi och miljövetenskap

   Author : Jonna Petersson; [2023-06-22]
   Keywords : Mercury; deposition; transformation; remediation; ecosystem impact; human health;

   Abstract : Mercury is a metal that can transform between different forms in both the atmosphere and in ecosystems. The transformation as well as properties of the different mercury compounds affect when, how and where the effects will emerge. 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.
