1. 21. Assessing the Extent of Diffuse Liver Disease: Quality Assurance of Magnetic Resonance Elastography (MRE)

   University essay from Umeå universitet/Institutionen för fysik

   Author : Anna Åkvist; [2022]
   Keywords : ;

   Abstract : The mechanical properties of liver tissue such as stiffness are closely correlated with various diseases. Magnetic resonance elastography (MRE) aims at estimating these mechanical properties by imaging the waves induced by an external driver in the liver. READ MORE

3. 22. Computational modelling of photosynthetic excitons coupled to a microcavity

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

   Author : Ilmari Turunen; [2022]
   Keywords : Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

   Abstract : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). READ MORE

4. 23. NVH analysis and optimization of electric powertrain

   University essay from KTH/Maskinkonstruktion (Inst.)

   Author : Anujit Dafle; [2022]
   Keywords : Electric powertrain; Gear whine; Noise Vibration Harshness NVH ; Elektrisk drivlina; kuggvin; buller och vibrationer;

   Abstract : With increasing focus on electromobility many companies are developing vehicles powered by an electric energy source. Previously, engines used to be the most prominent source of noise in a traditional Internal Combustion Engine (ICE) vehicle. READ MORE

5. 24. Quantum Computing in Nuclear Physics

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

   Author : Luca Bernecker; [2022]
   Keywords : quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

   Abstract : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. READ MORE

6. 25. Enhancing Sensing in Nanoscale: Investigation of Smart Nanomechanical Cantilever Array

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Hiruy Michael Weldegiorgish; [2022]
   Keywords : Cantilever; AFM; Biosensor; Piezoresistive sensor; Piezoelectric actuator; Kantilever; AFM; Biosensor; Piezo -resistorer; Piezo-elektiska pådrivare;

   Abstract : In this report, a novel smart nanocantilever with self-deflection sensor using embedded piezo-resistor and self-actuation using integrated piezo-electric actuator is proposed, designed and simulated to enable highly sensitive label free biosensor and ultra-short cantilever probe for AFM applications. The smart nanocantilever comprises of a triangular Si3N4 nanocantilever (10µm long, 400nm width and 100nm thickness) connected to a multi-layer support structure (Si3N4 (100nm)/PZT (100nm)) having n-type silicon piezo resistor (7µm long ,2µm width and 20nm thickness) embedded in the Si3N4 layer in both the support structure and nanocantilever.
