  1. 16. Modelling and assessment of energy performance with IDA ICE for a 1960's Mid-Sweden multi-family apartment block house

    Magister-uppsats, Högskolan i Gävle/Energisystem

    Författare :Lierni Arnaiz Remiro; [2017]
    Nyckelord :retrofit; building’s energy performance; simulation; modelling; heat transfer; thermal bridge; IDA ICE; COMSOL.;

    Sammanfattning : The present thesis has been carried out during the spring of 2017 on behalf of Gavlegårdarna AB. This is a public housing company in Gävle (Sweden) which is a large energy consumer, over 200 million SEK per year, and has the ambitious goal of reduce its energy consumption by 20 % between 2009 and 2020.

  3. 17. Försämrade materialegenskaper i aluminiumkonstruktioner - Liquid Metal Embrittlement inducerat av gallium

    Uppsats för yrkesexamina på grundnivå, Försvarshögskolan

    Författare :Anders Theorin; [2016]
    Nyckelord :Liquid Metal Embrittlement; Sabotage; Yield strength; Strength reduction; Tensile Strength; Elasticity; Gallium; Military System; Försprödning; Infiltration; Tekniska System; Störa; Hållfasthet; Sträckgräns; Brottgräns; Aluminium;

    Sammanfattning : Denna studie undersöker möjligheten att påverka fientliga konstruktioner genom användandet av en effektiv metod, som kan medge en liten risk att upptäckas. Den tänkta påverkan uppnås genom fenomenet Liquid Metal Embrittlement (LME), med vilken höghållfasta metaller kan påverkas så mycket att de kollapsar av sin egenvikt. LÄS MER

  4. 18. Energy Audit for an Old Industrial Building in Gävle

    Magister-uppsats, Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknik

    Författare :Unai Cano; [2016]
    Nyckelord :;

    Sammanfattning : The Swedish industrial sector has overcome the oil crisis and has maintained the energy use constant even though the production has grown. This has been achieved thanks to the development of several energy policies, by the Swedish government, towards the 2020 goals. LÄS MER

  5. 19. Growing green values : Mapping ecosystem services on urban agricultural sites in Buenos Aires

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Kajsa Ignell; Åsa Bugge Marin; [2016]
    Nyckelord :urban agriculture; Buenos Aires; Argentina; mapping ecosystem services; food security; social inclusion;

    Sammanfattning : Buenos Aires, the capital city of Argentina, face some of the same problems as all megacities across the world. Increased land-use and a higher amount of built areas in and around the city of Buenos Aires leads to losses in ecosystem services. LÄS MER

  7. 20. Two-dimensional hydrodynamic modeling of overland flow and infiltration in a sustainable drainage system

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära; Lunds universitet/Ekosystemteknik (CI)

    Författare :Karl Gunnarsson; [2015]
    Nyckelord :infiltration modeling; MIKE 21; rainfall-runoff modeling; SUDS; urban hydrology; Technology and Engineering;

    Sammanfattning : As a part of the GrönNano project at Luleå University of Technology, a sustainable drainage system, composed of infiltration surfaces and a wale,has been subject to hydrological measurements and modeling. The aim of this study was to identify the conditions under which it is possible to model the hydrological processes of that system adequately, using the two-dimensional hydrodynamic modeling software MIKE 21 equipped with an infiltration and leakage module.
