  1. 1. Development of life cycle cost model and analyses for railway switches and crossings

    Author : Arne Nissen; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Life Cycle Cost; RAMS; Maintenance Decision; Railway Infrastructure; Switches and Crossings; Industrial engineering and economy - Industrial organisation; administration and economics; Livscykelkostnad; RAMS; Underhållsbeslut; Järnväg; Spårväxlar; Industriell teknik och ekonomi - Industriell organisation; administration och ekonomi; Drift och underhållsteknik; Operation and Maintenance;

    Abstract : Infrastructure managers need to have a safe and available infrastructure, so that train operators can deliver a transport product at an affordable price. In the future, as traffic volume increases, higher utilisation of the existing capacity, less time for maintenance and fewer unplanned interruptions will be critical for meeting the ever increasing need of transport capacity.

  2. 2. Railway capacity analysis : Methods for simulation and evaluation of timetables, delays and infrastructure

    Author : Anders Lindfeldt; Bo-Lennart Nelldal; Ullrich Martin; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Järnvägsgruppen - Kapacitet; Järnvägsgruppen - Kapacitet;

    Abstract : In this thesis the symptoms and underlying behaviour of congestion on railways are analysed and discussed. As well as in many other countries, Sweden faces increasing demand for transportation. To meet this new demand, railways play an important role. READ MORE

  3. 3. A Novel Method for Adaptive Control of Manufacturing Equipment in Cloud Environments

    Author : Göran Adamson; Philip Moore; Lihui Wang; Robert Harrison; Högskolan i Skövde; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Function Block; Adaptive control; Robot-Control-as-a-Service; Cloud Manufacturing; Production and Automation Engineering; Produktion och automatiseringsteknik;

    Abstract : The ability to adaptively control manufacturing equipment, both in local and distributed environments, is becoming increasingly more important for many manufacturing companies.One important reason for this is that manufacturing companies are facing increasing levels of changes, variations and uncertainty, caused by both internal and external factors, which can negatively impact their performance.

  4. 4. SPICE modeling of ultrasound systems : improvements and verifications

    Author : Jonny Johansson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Abstract : The success of modern electronics is built on the possibility to accurately predict system behavior by the use of simulation tools. This paradigm can be extended to components such as sensors attached to the electronics. READ MORE

  5. 5. Punctuality and railway maintenance

    Author : Birre Nyström; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : Long and frequent train delays, striking many periodically make headlines. The question is raised: what might be done about it? The on-going deregulation of the Swedish railway, with more actors entering the market, contributes to the question's topicality. In this thesis, problems and symptoms concerning punctuality are described and analysed. READ MORE
