1. 1. The Rise of a Great Wall of Sand in the South China Sea - A Qualitative Idea Analysis on How China Has Demonstrated Its Assertiveness Over the South China Sea during Xi Jinping's Second Term as President of China

   Kandidat-uppsats, Lunds universitet/Statsvetenskapliga institutionen

   Författare :Lucas Leverström; [2024]
   Nyckelord :South China Sea; China; Offensive Realism; Law and Political Science;

   Sammanfattning : This thesis investigates how China has demonstrated its assertiveness in the South China Sea throughout Xi Jinping's second presidential term, from March 2018 to March 2023. Employing the theoretical framework of Offensive Realism, the thesis seeks to unravel the motivations behind China's assertiveness in the South China Sea, contributing to a nuanced understanding of its strategic behavior and geopolitical objectives in the region.

3. 2. Investigation of coarse-grid CFD approach for nuclear engineering application

   Master-uppsats, KTH/Fysik

   Författare :Michela Casarella; [2023]
   Nyckelord :Thermal-hydraulics; Nuclear reactor; CFD; Sub-channel; Coarse-grid; Turbulence; Pressure drop; Termisk-hydraulik; kärnreaktor; CFD; underkanal; grovkornigt nät; turbulens; tryckfall;

   Sammanfattning : In this thesis, an innovative coarse grid CFD approach is developed that aims toexploit the capabilities of sub-channel codes and CFD methods while overcoming theirlimitations. In the approach, a very coarse mesh is implemented in the CFD softwareOpenFOAM and a new wall treatment, based on the traditional concept of the wallfunction, is applied to the wall boundary conditions of the domain to take into accountthe low resolution of the grid which does not allow to effectively capture the effect of thesolid walls on the thermo-hydraulics of the flow.

4. 3. Exercise Classification with Machine Learning

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Joel Ekstrand; [2023]
   Nyckelord :Machine learning; signal processing; noise reduction; feature extraction; exercise classification; machine learning; signalprocessering; brusreducering; feature extraction; rörelseklassificering;

   Sammanfattning : Innowearable AB has developed a product called Inno-XTM that calculates musclefatigue during three exercises: squat jumps, wall sit, and leg extension. Inno-X uses an accelerometer and a surface electromyography sensor. LÄS MER

5. 4. Development of HVAC simulations for truck cabins using OpenFOAM

   Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

   Författare :Junaid Haider; [2023]
   Nyckelord :Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

   Sammanfattning : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. LÄS MER

7. 5. Towards Large Scale Façade Parsing: A Deep Learning Pipeline Using Mask R-CNN

   Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

   Författare :MOLA AYENEW; [2022-04-27]
   Nyckelord :pipeline; semi-automated; building facade; parsing; panorama imagery; Google Street view; mapillary; Mask R-CNN; deep learning; inference; rectilinear projection;

   Sammanfattning : This thesis tries to find a methodology that create a working pipeline for building facade parsing, which allows to access large scale panorama imagery from Google Street View (GSV) and implement on deep learning models. We propose a semiautomated pipeline that integrates multiple systems for large-scale building facade parsing. LÄS MER
