  1. 21. Thermal response test : numerical simulations and analyses

    Författare :Anna-Maria Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering; VA-teknik; Urban Water Engineering;

    Sammanfattning : When constructing large borehole heat exchanger (BHE) systems, bedrock and borehole thermal properties are vital for a good design. Today's design programs presume conductive heat transfer in both borehole and bedrock. LÄS MER

  3. 22. Towards Environmental Informatics for Building Stocks. A Conceptual Model for an Environmental Building Stock Information System for Sustainable Development - EBSIS

    Författare :Liane Thuvander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building stock; information system; environmental system analysis; energy flows; building stock information system; material flows; environmental informatics; urban system analysis; environment; sustainable sevelopment;

    Sammanfattning : The Swedish building sector uses a considerable amount of all materials and all energy used in Sweden. Knowledge about the existing building stock, its impact on the environment related to the use of material and energy, however, is limited and target settings for environmental objectives and decision making are based on vague information.

  4. 23. Externally unbonded post-tensioned CFRP tendons : a system solution

    Författare :Anders Bennitz; Chris Burgoyne; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFRP; prestress; tendon; external; unbonded; anchorage; beams; CFRP; förspänning; vajer; utanpåliggande; icke vidhäftande; förankring; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The introduction of Fibre Reinforced Polymers (FRP) to the civil engineering market in the late 1980s resulted in the emergence of a range of new tools for rehabilitating and strengthening concrete structures. Strengthening using FRPs is typically accomplished using non-prestressed externally bonded FRPs. LÄS MER

  5. 24. Environmental pollutants and the reproductive system in birds : Developmental effects of estrogenic compounds

    Författare :Cecilia Berg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Avian embryo; test system; xeno-estrogen; endocrine disruption; reproductive organ differentiation; oviduct; testis; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Ecotoxicology; ekotoxikologi;

    Sammanfattning : A number of environmental pollutants have been shown to mimick the action of the female sex hormone estrogen and are, therefore, suspected to be responsible for reproductive abnormalities seen in wildlife. Test systems which can be used in hazard and risk assessment of chemicals with estrogenic effects are consequently needed. LÄS MER

  7. 25. Enabling Test Automation for Industrial PLC Programs

    Författare :Mikael Ebrahimi Salari; Eduard Paul Enoiu; Wasif Afzal; Cristina Seceleanu; Jee Eunkyoung; Mälardalens universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PLC; PLC Testing; Automated Testing; PyLC; EARS Syntax; FBD; ST; Computer Science; datavetenskap;

    Sammanfattning : Testing safety-critical systems, particularly those controlled by Programmable Logic Controllers (PLC), is crucial for ensuring the safe and reliable operation of industrial processes. This thesis addresses the critical need for automated testing of safety-critical PLC systems used in various industrial settings. LÄS MER
