  1. 16. Geographical Information Technologies – Decision Support for Road Maintenance in Uganda

    Författare :Lydia Mazzi Kayondo-Ndandiko; Blekinge Tekniska Högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Data Model; Dynamic Segmentation; Geographical Information Technologies GITs ; Geographical Information Systems for Transportation GIS-T ; Linear referencing; Methodological Framework; Research and Development; Road maintenance; Road Infrastructure Maintenance RIM ; Science Technology and Innovation; Spatial Data Infrastructure; Uganda;

    Sammanfattning : This study set out to develop a framework within which the use of Geographical Information Technologies (GITs) can be enhanced in Road Infrastructure Maintenance (RIM) in Uganda. Specifically it was guided by 3 objectives; 1. To assess the gaps in the use of GITs for RIM in Uganda and the limitations to accessing these technologies, 2. LÄS MER

  3. 17. Data-driven predictive maintenance planning and scheduling

    Författare :Mahdieh Sedghi; Bjarne Bergquist; Erik Vanhatalo; Ramin Karim; Luleå tekniska universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik och logistik; Quality Technology and Logistics;

    Sammanfattning : The railway track network is one of the major modes of transportation and among a country’s most valuable infrastructure assets. Maintenance and renewal of railway infrastructure have a vital role in safety performance, the quality of the ride, train punctuality, and the life cycle cost of assets. LÄS MER

  4. 18. On the establishment of effective condition-based maintenance for oil-filled electrical transformers to reduce failures due to copper corrosion problems and its role toward sustainable energy

    Författare :Ramsey Jadim; Mirka Kans; Lina Bertling Tjernberg; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CBM; CM procedures; corrosion problems; transformer oil analysis; corrosive sulfur; transformer failures; sustainable maintenance; sustainable energy supply; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Oil-filled electrical transformers are critical equipment for modern societies where a sustainable energy supply is required. Recently, many severe fire and explosion accidents of transformers have been reported due to copper corrosion problems in the form of copper sulfide deposits on the windings. LÄS MER

  5. 19. On maintenance management of wind and nuclear power plants

    Författare :Julia Nilsson; Lina Bertling; Ulf Sandberg; KTH; []
    Nyckelord :electrical poduction systems; windpower; nuclear power; maintenance management; RCM; RCAM; LCC; mathematical optimization; opportunistic maintenance;

    Sammanfattning : Electrical production in Sweden today is mainly from nuclear and hydro power. However, there is large increase in renewable energy like wind power and the installed new capacity goals are large. Several electrical production sources are important for the sustainability of the energy system. LÄS MER

  7. 20. Tolerance Analysis Framework for Cutting Tool Interface Design

    Författare :Soner Camuz; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variation simulation; reliability-based optimization; tolerance analysis; cutting tool interface design; geometry assurance;

    Sammanfattning : Tolerance analysis of cutting tool interface designs is a field with many opportunities for further development of existing methodologies. Cutting tool interface designs require multiple contacting surfaces, allocating the stress generated from the cutting forces, to avoid excessive deformation of the interface. LÄS MER
