1. 1. U - Net Based Crack Detection in Road and Railroad Tunnels Using Data Acquired by Mobile Device

   University essay from KTH/Geoinformatik

   Author : Kepan Gao; [2022]
   Keywords : U-Net; deep learning; tunnel monitoring; structural health monitoring; crack detection; mobile mapping system;

   Abstract : Infrastructures like bridges and tunnels are significant for the economy and growth of countries, however, the risk of failure increases as they getting aged. Therefore, a systematic monitoring scheme is necessary to check the integrity regularly. READ MORE

3. 2. Detection of facade cracks using deep learning

   University essay from Mittuniversitetet/Institutionen för elektronikkonstruktion

   Author : Linus Eriksson; [2020]
   Keywords : Machine learning; Deep learning; Dataset simulation; Crack classification; Blender; Feature Extraction; Maskininlärning; Djupinlärning; Simulering av dataset; Klassificering av sprickor; Blender; Feature Extraction;

   Abstract : Facade cracks are a common problem in the north of Sweden due to shifting temperatures creating frost in the facades which ultimately damages the facades, often in the form of cracks. To fix these cracks, workers must visually inspect the facades to find them which is a difficult and time-consuming task. READ MORE

4. 3. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

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

   Author : Alejandro Simó Vesperinas; [2018]
   Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

   Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE

5. 4. Automatic image-based road crack detection methods

   University essay from KTH/Geodesi och satellitpositionering

   Author : Liene Some; [2016]
   Keywords : Road cracks; Crack detection; Mobile mapping; Deep learning; CrackIT; Caffe;

   Abstract : Pavement crack detection is an important procedure in road maintenanceand traffic safety. Traditionally, the road inventory was performed by field inspection, now it is replaced by the evaluation of mobile mapping system images. The acquired images are still a significant source of temporal condition of thepavement surface. READ MORE

6. 5. Classification of leakage detections acquired by airborne thermography of district heating networks

   University essay from Datorseende; Tekniska högskolan

   Author : Amanda Berg; [2013]
   Keywords : Machine learning; remote sensing; infrared images;

   Abstract : In Sweden and many other northern countries, it is common for heat to be distributed to homes and industries through district heating networks. Such networks consist of pipes buried underground carrying hot water or steam with temperatures in the range of 90-150 C. Due to bad insulation or cracks, heat or water leakages might appear.
