    Sammanfattning : Faced with an acute problem of housing options during the 1960s, the Swedish government introduced a nationwide campaign of ‘A Million New Homes’. In order to achieve the aim of the campaign, the construction of these homes depends on cheap and fast building methods which do not result in the homes being energy efficient nor are they equipped with good acoustical properties.

  3. 7. Innovative AMR based magnetometer for space application : Simulation and Characterization of a multilayer solution

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Alberto Isernia; [2016]
    Nyckelord :;

    Sammanfattning : During the recent years, the space technology trend was pointing towards the miniaturization of all its components in order to achieve a smaller and lightweight satellite with low power and low noise components. A possible solution to this request can be given by the anisotropic magnetoresistance (AMR) based sensors which present good miniaturizability and low power consumption. LÄS MER

    M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Carl-Johan Eriksson; Jonas Erlingsson; [2015]
    Nyckelord :CFRP; GFRP; fiber reinforced polymer; structural composites; hybrid materials; bridge construction; prefabrication; Eurocode; lightweight materials; industrial prefabrication; pultrusion; RTM; resin transfer moulding; hybridmaterial; alternativvalskalkyl; fiberförstärkta polymerer; glasfiber; kolfiber; brokonstruktion; prefab; prefabricering; byggteknik; byggkonstruktion; brobyggnation; lättviktsmaterial; komposit; fiberkomposit; industriellt byggande; industriell prefabrikation; byggmetoder; FRP; pultrudering; pultrusion; dimensioneringsregler; eurokod;

    Sammanfattning : FRP stands for Fiber Reinforced Polymer. FRP materials have yet to be introduced inbridge construction in Sweden. Composite materials can through combined componentsand manufacturing processes be tailored to fit advanced bridge designs. FRP materials arestrong, durable and of low weight. LÄS MER

  5. 9. Resonans

    Kandidat-uppsats, KTH/Byggvetenskap

    Författare :Arezo Partovi; Jenny Svärd; [2014]
    Nyckelord :Resonans; egensvängning; dämpning; konstruktion;

    Sammanfattning : This report describes how the system may be exposed to oscillations and how this can lead to resonance. Resonance is a phenomenon that occurs when a system is affected by external periodic oscillations with frequencies close to the system's natural frequencies. LÄS MER

  7. 10. Modal Testing and Structural Identification

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Byggnadsmekanik

    Författare :Tobias Kristensson; [2014]
    Nyckelord :Modal testing; Modal analysis; Structural identification; Vibration; Signal; EMA; OMA; Technology and Engineering;

    Sammanfattning : Bridges have been built around the world for at least 3000 years and have made it possible for man to travel over obstacles like valleys and rivers, which has contributed to the rapidly growing infrastructure we have today. Efforts made to save materials and reduce production costs have led to lighter and slender structures, which in turn can cause dynamic problems where the bridge is sensitive to vibrations. LÄS MER
