1. 1. The visibility of stellar transients in the Galactic Centre

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

   Author : Jonathan Ström; [2024]
   Keywords : Physics and Astronomy;

   Abstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

3. 2. Inductive fast charging of IoT devices : An in-depth analysis of short-range wireless charging technologies based on induction

   University essay from Umeå universitet/Institutionen för fysik

   Author : Franz Wikner; [2024]
   Keywords : Electromagnetic power transfer; Inductive power transfer; Short distance WPT;

   Abstract : In the era of Internet of things (IoT), sensor-equipped devices exchange data over networks. In battery powered IoT devices, the lifespan of the devices is often much longer than the battery life, leading to multiple costly and environmentally hazardous battery replacements during the operational life of the devices.

4. 3. Deep Neural Networks as SurrogateModels for Fuel Performance Codes

   University essay from Uppsala universitet/Tillämpad kärnfysik

   Author : Wenhan Zhou; [2023]
   Keywords : Transuranus; AI; Nuclear Fuel Rods;

   Abstract : The core component of a nuclear power plant is the reactor and the fuel rods that supply it with fission fuel. Efficient and safe energy extraction is thus highly dependent on the reactor design and the conditions of the fuel rods. To anticipate high-quality operation and potential risks in advance, one must perform simulations on the fuel rods. READ MORE

5. 4. Att förebygga senskador hos ridhäst : med fokus på degenerativa skador

   University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

   Author : Vera Hultman; [2023]
   Keywords : den ytliga böjsenan; sendegenerering; träning; benskydd; underlag; häst;

   Abstract : En senskada hos ridhästen leder till långa konvalecentperioder och obrukbara hästar vilket resulterar i en bristande hästvälfärd, stora ekonomiska kostnader för hästägare och att omvärlden ser negativt på ridsporten. För att sprida kunskap kring de åtgärder som kan vidtas för att förebygga senskador i den ytliga böjsenan hos ridhästar har denna litteraturstudie genomförts. READ MORE

6. 5. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Sigge Axelsson; Jonas Gartner; Axel Stafström; [2023]
   Keywords : high-voltage; low-current; low-power; DC DC; DC-DC; high-gain; converter; electrohydrodynamic pump; EHD; transformerless converter; Royer-based converter; resonant Royer oscillator; Cockroft-Walton voltage multiplier; CWVM; voltage multiplier; series-connected positive-negative voltage multiplier; SPNVM; planar air-core transformer; planar transformer; high-freqency Royer-based converter; overcurrent protection; LT8331; gallium nitride; GaN; planar PCB-integrated transformers;

   Abstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE
