1. 1. Sim2Real: Generating synthetic images from industry CAD models with domain randomization

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Duruo Li; [2023]
   Nyckelord :;

   Sammanfattning : Deep learning methods for computer vision applications require massive visual data for model training. Although it is possible to utilize public datasets such as ImageNet, MS COCO, and CIFAR-100, it becomes problematic when there is a need for more task-specific data when new training data collection typically is needed.

3. 2. Evaluation of bank erosion and stability analysis along Rönne å at Ängelholm, Sweden

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Arnold Mate Kalimukwa; Abuzack Juma Mohamed; [2021]
   Nyckelord :HEC-RAS; BSTEM; cross section; erosion; sediment transport; deposition; bank stability; safety factor; Technology and Engineering;

   Sammanfattning : This master thesis report presents the results of evaluation of bank erosion and stability analysis along Rönne å (river) at Ängelholm, located in south-west of Sweden within Scania. The main objectives cover building a hydrodynamic model, studying parameters that define sediment transport, modelling sediment transport within the river, mapping out erosive stretches and comparing to earlier observational study conducted by Norconsult in 2013, and finally conducting analysis of bank stability in most erosive stretches.

4. 3. Monitoring and Modelling of the Abiskojåkka Bridge

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

   Författare :Kasper Furenstam; [2020]
   Nyckelord :Prestressed bridge; Abisko; Monitoring; thermal effects; FEM;

   Sammanfattning : The infrastructure of today is getting older and problems caused by deterioration over time is affecting the service life of these structures. In Sweden most of the existing bridges were constructed 60 to 70 years ago, rising the need to determine the state of health of the bridges as the maintenance costs will increase heavily. LÄS MER

5. 4. Domain adaptation from 3D synthetic images to real images

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Författare :Krishna Himaja Manamasa; [2020]
   Nyckelord :Domain adaptation; Transfer learning; Deep learning; 3D point clouds;

   Sammanfattning : Background. Domain adaptation is described as, a model learning from a source data distribution and performing well on the target data. This concept, Domain adaptation is applied to assembly-line production tasks to perform an automatic quality inspection. Objectives. LÄS MER

7. 5. Identification and quantification of concrete cracks using image analysis and machine learning

   Master-uppsats, KTH/Bro- och stålbyggnad

   Författare :JUAN CAMILO AVENDAÑO; [2020]
   Nyckelord :Unmanned Aerial Vehicle; UAV; Convolutional Neural Network; CNN; Crack quantification; Bridge inspection.;

   Sammanfattning : Nowadays inspections of civil engineering structures are performed manually at close range to be able to assess damages. This requires specialized equipment that tends to be expensive and to produce closure of the bridge. Furthermore, manual inspections are time-consuming and can often be a source or risk for the inspectors. LÄS MER
