  1. 6. Modelling LCC for Different Indoor Climate Systems

    Författare :Dennis Johansson; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kallt klimat; bostäder; kontor; skolor; samlingslokaler; inomhusklimat; VVS; uppvärmning; ventilation; luftkonditionering; livscykelkostnader; kostnader; optimering; beräkningsmetoder; beräkningsmodeller; teori;

    Sammanfattning : The indoor climate system, which serves a building with a proper indoor air quality and thermal comfort, has been predominantly designed based on the initial investment costs. A life cycle approach could improve both the economic and environmental performance since the energy use would decrease. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Krossning; siktning; sortering; krossanläggningar; processer; produkter; kostnad; entreprenadindustri; Gruvindustri; ballastindustri; beräkningar;

    Sammanfattning : The mining and quarrying industries represent a highly important sector of the Swedish economy. The mining industry operates globally, whereas the quarrying industry operates on a regional/local basis. LÄS MER

  5. 9. Science and Technology for Americium Transmutation

    Författare :Milan Tesinsky; Janne Wallenius; Piero Ravetto; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Americium could be seen as the most troublesome element that is presentin nuclear fuel. This thesis offers different points of view on the possibility ofamericium transmutation. The first point of view elaborates simulations ofamericium-bearing facilities, namely nuclear data, a popular computationalcode and modeling techniques. LÄS MER

  7. 10. Acoustic excitation and transmission of lightweight structures

    Författare :Jonas Brunskog; Teknisk akustik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; point mobility; Lamb waves; wood.; Building construction; plate excitation; cavities; near-periodicity; nearly periodic; sound insulation; timber; structural acoustics; spatial Fourier transform; resilient device; prediction model; periodic; lightweight; ISO tapping machine; airborne noise; Building acoustics; impact noise; Byggnadsteknik;

    Sammanfattning : In order to increase our knowledge of the sound transmission and radiation processes of lightweight wall and floor structures, theoretical models are needed. Detailed models may form a valuable tool. In lightweight floor structures, impact sound insulation is perhaps the most important property to consider. LÄS MER
