1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

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

   Author : Emelie Zhu; [2024]
   Keywords : Physics and Astronomy; Technology and Engineering;

   Abstract : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. READ MORE

3. 2. Incremental Re-tokenization in BPE-trained SentencePiece Models

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Simon Hellsten; [2024]
   Keywords : BPE; Byte Pair Encoding; SentencePiece; NLP; Natural Language Processing; Tokenization; Re-tokenization;

   Abstract : This bachelor's thesis in Computer Science explores the efficiency of an incremental re-tokenization algorithm in the context of BPE-trained SentencePiece models used in natural language processing. The thesis begins by underscoring the critical role of tokenization in NLP, particularly highlighting the complexities introduced by modifications in tokenized text. READ MORE

4. 3. Generation and detection of entangled single-photon pairs

   University essay from Uppsala universitet/FREIA

   Author : Gabriella Tesfamichael Habtezion; [2024]
   Keywords : ;

   Abstract : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. READ MORE

5. 4. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

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

   Author : Muhammad Hashir Zaheer; [2023]
   Keywords : High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

   Abstract : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. READ MORE

6. 5. Probing Charm Production with Three-Particle Correlations in pp Collisions

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Author : Kim Haupt; [2023]
   Keywords : pp collisions; charm production; three-particle correlation; Pythia; Physics and Astronomy;

   Abstract : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. READ MORE
