  1. 1. Modeling of a ball contact with a coated plate

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mohammadreza Saeedi; [2023]
    Keywords : Pin on disc tribometer; coating; contact mechanics; finite element method; tribology; Pin on disc tribometer; beläggning; kontaktmekanik; finita elementmetod; tribologi;

    Abstract : During tightening of a screw, the variation in friction will affect the force acting on the joint, especially when tightening using torque as a control parameter. So, it is crucial to have a proper understanding of the contact mechanism and friction in the screw head to joint and thread interfaces. READ MORE

  3. 2. Fire Resistance Test of Cross Laminated Timber Joints

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Oliver Cato; [2022]
    Keywords : CLT; Joints; Fire; resistance; Korslaminerat; trä; skarvar; Brand; motstånd;

    Abstract : The increased popularity of timber buildings has heightened the demand for more knowledge on how tomake these buildings safer. In many cases, parts of wooden constructions are prebuilt in factories that later are delivered to the building site. Transportation by road limits the sizes of the parts. READ MORE

  4. 3. Detecting Defective Rail Joints on the Swiss Railways with Inception ResNet V2 : Simplifying Predictive Maintenance of Railway Infrastructure

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Anton Lu; [2022]
    Keywords : Rail Defect Detection; Rail Image Classification; Rail Joints; Object Detection; Image Classification; Deep Learning; Järnvägsfeldetektering; Järnvägsbildigenkänning; Järnvägsskarvar; Objectigenkänning; Bildklassificering; Djupinlärning;

    Abstract : Manual investigation of railway infrastructure is a labor-intensive and time-consuming task, and automating it has become a high priority for railway operators to reduce unexpected infrastructure expenditure. In this thesis, we propose a new image classification approach for classifying defect and non-defective rail joints in image data, based on previous fault detection algorithms using object detection.
