1. 1. Investigating the potential correlations between metal and metalloid concentrations and soil color : A Minor Field Study on the island province of Marinduque, Philippines

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Ivana Pia Saric Söderholm; Erik Readwin; [2023]
   Keywords : Marinduque; Metal and Metalloid; Nix Pro 2 Color Sensor; Philippines; Soil color; X-Ray Fluorescence XRF ; Filippinerna; Jordfärg; Marinduque; Metall och Metalloid; Nix Pro 2 Color Sensor; Röntgenfluorescens XRF ;

   Abstract : This study was carried out as a bachelor's thesis at KTH Royal Institute of Technology during the spring of 2023, investigating the correlation between the color with the concentration of various metal and metalloids (MMs) in the soil of Marinduque, The Philippines. With a history of mineral exploitation, notably copper and gold, the island has faced persistent environmental challenges, exemplified by the catastrophic waste spills in 1993 and 1996 that contaminated the Boac and Mogpog Rivers.

3. 2. Monte Carlo study of disorder in electronic tight-binding models

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk fysik

   Author : Carl Pettersson; [2023]
   Keywords : Monte Carlo; Tight-binding model; Falicov-Kimball model; Physics and Astronomy;

   Abstract : Oftentimes solids are described by uniform, periodic lattices. In reality, however, there is often some disorder on some of the sites in the lattice. This disorder may come from, for example, there being a different type of atom or tightly bound electrons resulting in a larger on-site potential, affecting the electronic properties of the lattice.

4. 3. Numerical Simulations of Metal Recovery for Battery Recycling

   University essay from KTH/Processteknologi

   Author : Morgan Ölander; [2023]
   Keywords : Batteriåtervinning; Metall återvinning; Kristallisation; Computational Fluid Dynamics CFD ; Populationsbalansmodellering; Battery recycling; Metal recovery; Crystallisation; Computational Fluid Dynamics CFD ; Population balance modelling;

   Abstract : Den pågående elektrifieringen av transport och samhälle kräver utveckling av nya metoder för återvinning av batterier. Hydrometallurgi som fokuserar på selektiv kristallisation av metaller är ett intressant alternativ för dessa ändamål. Dessa system kan studeras genom modellering och simulering. READ MORE

5. 4. Heart Rate Measurement using a 60 GHz Pulsed Coherent Radar Sensor

   University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

   Author : Melina Al Nasser; Linn Gromert; [2022]
   Keywords : Signal processing; EKG; Heart rate; Radar sensor; Neural network; Acconeer; Technology and Engineering;

   Abstract : Heart rate is today measured in various ways, but they all include contact with the skin. Measuring heart rate contactless would be a more efficient method in healthcare and would also benefit people suffering from skin problems. It has been proven that it is possible to use radar to measure heart rate. READ MORE

6. 5. Automatic waste sorter : Automatic sorting of metal and non-metal objects

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

   Author : Vishi Sharan; Merna Iskander; [2022]
   Keywords : Waste; Mechatronics; Micro controller; Inductive proximity sensor; Metal; Avfall; Mekatronik; Mikro kontroller; Induktiv närhets sensor; Metall;

   Abstract : Our earths resources are not endless, so it is important to avoid wasting our planets natural resources. Recycling metal saves 95% more energy than producing new metal from ore, which is why it is necessary to reuse metal. Waste sorting is very important in today’s modern society as the demand for metals is increasing at a rapid rate. READ MORE
