3. 2. A numerical comparison of the thermoacoustics for different equivalence ratios for n-dodecane using LES

   Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

   Författare :Björn Jarfors; [2023]
   Nyckelord :Computational Fluid Dynamics; Bluff-body stabilised flames; Large Eddy Simulation; Thermoacoustics; Acoustics; NEUMANN Project; Jet engines; Aero engines; Airplanes; Combustion; Numerics; Technology and Engineering;

   Sammanfattning : Klimatförändringarna påverkar vår värld och det behövs ett mer hållbart samhälle. Flygindustrin är i behov av förändring, men flygmotorer är mycket komplexa och tar tid att utveckla. Termoakustiska instabiliteter har kraften att förstöra en motor, men också att minska miljöpåverkan. LÄS MER

4. 3. Pre-Existing Film Music Re:sourced : Technical Aspects and Narratological Implications of Audible Diegetic Transitions in Joker and Other Films

   Master-uppsats, Uppsala universitet/Institutionen för musikvetenskap

   Författare :Martin Danstål Skiöld; [2023]
   Nyckelord :film music; technical aspects; narratological implications; audible diegetic transitions; transaural displacements; diegetic; non-diegetic; intra-diegetic; meta-diegetic; supra-diegetic; trans-diegetic; sound advance; bridge; lag; story; discourse; instant; gradual; emotive; grounding; narrow; wide; Joker; Baby Driver; Coda; Guardians of the Galaxy; Star Wars;

   Sammanfattning : This thesis concerns itself with a phenomenon found in film music that can be described as audible diegetic transitions. In short, an audible diegetic transition occurs when film music shifts from one implied musical placement to another by changing its pre­sented sound quality. LÄS MER

5. 4. Exploring Alarm Data for Improved Return Prediction in Radios : A Study on Imbalanced Data Classification

   Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Matematiska institutionen

   Författare :Sofia Färenmark; [2023]
   Nyckelord :Imbalanced data classification; LASSO; Boruta; SVM; RFC; neural network; decision tree; AUC; AUPRC;

   Sammanfattning : The global tech company Ericsson has been tracking the return rate of their products for over 30 years, using it as a key performance indicator (KPI). These KPIs play a critical role in making sound business decisions, identifying areas for improvement, and planning. LÄS MER

7. 5. Att förvänta sig det oväntade : en teoriprövande fallstudie om överraskning, chock och exploatering

   Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

   Författare :Mathias Sundström; [2023]
   Nyckelord :Organisatorisk kollaps; stridens psykologi; stridsvilja; moral; sammanhållning;

   Sammanfattning : The psychological dimension of war is frequently neglected compared to the physical aspects. Storr has shown that a psychological collapse of the opponent can lead to an organizational breakdown, but the theories have mainly been tested through simulations. LÄS MER
