1. 1. Fano Resonances in Time-Dependent Wells

   University essay from Uppsala universitet/Materialteori

   Author : Anton Gregefalk; [2023]
   Keywords : Fano resonance; Floquet scattering; Pumped shot-noise; Linear band tilt; Quadratic band touching; Time periodic Hamiltonian;

   Abstract : Floquet’s theorem, a temporal analogue of Bloch’s theorem, is used for studying a time-dependent potential. With applications in cold atoms on optical lattices, quantum dots and more, there is a growing interest in Floquet engineering exotic materials and phases. READ MORE

3. 2. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

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

   Author : Nipon Roy; [2023]
   Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

   Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

4. 3. Automatic Recycling Sorting Unit: A platform designed to sort glass, plastic and metal

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

   Author : Anni Li; Agnes Agåker Karlsson; [2023]
   Keywords : Mechatronics; Recycling; Inductive sensor; Capacitive sensor; Loadcell; Mekatronik; Återvinning; Induktivsensor; Kapacitivsensor; Viktcell;

   Abstract : This report describes the design and construction of a tilting platform for sorting household waste, limited to plastic, glass, and metal. The platform utilizes a capacitive sensor to identify if an object is placed on the platform, an inductive sensor to detect metal, and a load cell to differentiate between plastic and glass based on their weight difference.

5. 4. Dynamics of a CRAFT : A simulation study on a Counter Rotating vertical Axis Floating Tilting wind turbine

   University essay from Uppsala universitet/Elektricitetslära

   Author : Benjamin Hedlund Peters; Linda Goude; [2023]
   Keywords : wind power; counter rotating; contra rotating; offshore wind; floating wind power; vertical axis wind turbine; VAWT; renewable energy;

   Abstract : In this thesis the Counter Rotating vertical Axis Floating Tilting wind turbine (CRAFT) has been explored by creating a simulation model in the program Simulink. The CRAFT prototype is a new type of wind turbine under development by World Wide Wind and Uppsala University with the aim to produce a large scale floating vertical axis wind turbine (VAWT) with two cone shaped counter rotating turbines.

6. 5. Solar cells to counter rising electricity prices : Self-consumption and profitability of solar cells for a SME in price area 2 in Sweden.

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Johan Bergdahl; [2023]
   Keywords : SME; Solar cells; Gävleborg County; Self-consumption; Matching;

   Abstract : Increases in electricity prices in Sweden during the second half of 2021 have created a great deal of concern among companies in Sweden. Some companies report that they have stopped their production temporarily when electricity prices have been high. READ MORE
