  2. 1. On the Volume Changes during the Solidification of Cast Irons and Peritectic Steels

    Author : Abel Tadesse; Michael Vynnycky; Hasse Fredriksson; Jacques Lacaze; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Volume changes; Solidification; Peritectic steel; Micro- and Macro-shrinkage; LVDT; GCI; NCI; Hypo- and Hypereutectic; Austenite; DTA; Dilatometry; BSE; Nuclei; Flake graphite; SDAS; Eutectic cells; Undercooled graphite; Simulation; Cooling rate; Microsegregation; austenite; Metastable region; δ-ferrite; Stable phase diagram; Grain refinement; Strain.; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : This thesis work deals with the volume changes during the solidification of cast irons and peritectic steels. The volume changes in casting metals are related to the expansion and/or contraction of the molten metal during solidification. Often, different types of shrinkage, namely macro- and micro-shrinkage, affect the casting quality. READ MORE

  4. 2. A Toolbox for Sensor Data Fusion in Industrial Automation

    Author : Björn Karlsson; Gustaf Olsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The work is focused on measurement for support in industrial automation and especially around industrial robots. The main thread in the work is the combination (fusion) of information from different sensors. READ MORE

  5. 3. Structural health monitoring using modern sensor technology : long-term monitoring of the New Årsta Railway Bridge

    Author : Merit Enckell; Håkan Sundqvist; Daniele Inaudi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Health Monitoring; bridges; sensory technology; fibre optics; concrete.; Building engineering; Byggnadsteknik;

    Abstract : Structural Health Monitoring (SHM) is a helpful tool for engineers in order to control and verify the structural behaviour. SHM also guides the engineers and owners of structures in decision making concerning the maintenance, economy and safety of structures. READ MORE

  6. 4. Structural health of bridges : monitor, assess and retrofit

    Author : Arvid Hejll; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Abstract : The research presented in this Licentiate thesis is intended to cover minor areas of the wide research area Structural Health Monitoring (SHM) of Civil Engineering Structures. SHM is broadly the knowledge maintaining our infrastructure by assessing the condition, often by monitoring or measurements, diagnose damages, analyse risk levels, by using inputs from measurements and diagnoses, and in the end retrofit, if needed.
