  1. 26. Technological properties of rock aggregates

    Författare :Eva Johansson; Richard Prikryl; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : The commission of technical geology is to apply geological knowledge to the field of constructional engineering, mining technology, environmental protection, architecture etc. The sector of infrastructure is highly dependent on the production of crushed rock materials as the main constituent of e.g. road and railway constructions.

  3. 27. Automated Squat Detection in Railway Switches & Crossings Using Vibration Measurements and Machine Learning

    Författare :Yang Zuo; Matti Rantatalo; Johan Odelius; Florian Thiery; Praneeth Chandran; Taoufik Najeh; João Carlos Elói De Jesus Pombo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Operation and Maintenance Engineering; Drift och underhållsteknik;

    Sammanfattning : Railway switches and crossings (S&Cs) play a vital role in the operational integrity of a railway network, and their malfunctioning poses substantial risks such as traffic disruptions, economic ramifications, and potential life-threatening accidents. Consequently, it becomes imperative to proactively identify potential defects in S&Cs at an early stage and maintain continuous monitoring of their condition to avoid adverse consequences. LÄS MER

  4. 28. Applying Microwave Technology in Short Range Radio Communication and Sensing Systems

    Författare :Emil Nilsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Microwave technology continues to reach new areas and applications. Microwavebased sensors create the possibility to sense objects in remote and hostile envi-ronments, while miniaturization makes the merge of radios, sensors, and com-puting into new small devices possible.

  5. 29. Modeling of fracture and damage in rubber under dynamic and quasi-static conditions

    Författare :Elsiddig Elmukashfi; Martin Kroon; Krishnaswami Ravi-Chandar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : Elastomers are important engineering materials that have contributed to the different technical developments and applications since the 19th century. The study of crack growth mechanics for elastomers is of great importance to produce reliable products and therefore costly failures can be prevented. LÄS MER

  7. 30. Wind Power Integration in Power Systems with Transmission Bottlenecks
