  1. 1. Design Investigation of Passive Radiators in Loudspeakers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Fabrice Dufberg; Valter Hamberger; [2024]
    Nyckelord :passive radiator; loudspeaker; speaker tuning; Thiele Small parameters; frequency response; Technology and Engineering;

    Sammanfattning : Passive radiators are components that can be integrated into loudspeakers to amplify the bass frequencies. To ensure good sound quality, the passive radiator, the speaker driver, and the loudspeaker enclosure must all be well-dimensioned and fine-tuned in relation to each other. LÄS MER

  3. 3. An exploration of the relationship between skeletal muscle mass and glucose intolerance in healthy young adults

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Philip Richard Evans; [2023]
    Nyckelord :Type 2 diabetes mellitus; fasting plasma glucose; impaired fasting glucose; longitudinal trajectory; incidence rate; Oralt glukostoleranstest; antropometriska mätningar; muskelmassa; typ 2 diabetes; glukosintolerans;

    Sammanfattning : Background Type 2 diabetes mellitus (T2DM) is a globally prevalent disease anticipated to double from 500 million diagnosed cases in 2021 to more than one billion by 2050. The investigation of the potentially protective effects of skeletal muscle mass on glucose intolerance may lead to the development of more precise screening protocols. LÄS MER

  4. 4. Klimatneutrala städers verklighet och utmaningar : En analys av klimatarbetet inom bygg- och anläggningssektorn för 23 svenska kommuner anslutna till Viable Cities och dess verksamma aktörer

    Uppsats för yrkesexamina på grundnivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Alfred Kawamoto Enarsson; Thoni Mathisen; Jani Vornanen; [2023]
    Nyckelord :Klimatarbete; klimatpåverkan; klimatomställning; återbruk; CO2e; färdplan; energianvändning; solceller; upphandling; miljöcertifiering;

    Sammanfattning : Purpose: The purpose of the work was to map how the 23 cities that have signed the climate contract with the Viable Cities innovation program are working with the climate transition, but also to gain insight into the companies' climate work in the construction sector. Method: The method for developing the basis for the work has been in the form of a literature study where previous work on the subject has been reviewed but also various data collections where information has been obtained from organizations and authorities, interviews with companies active in the industry and review of cities' climate roadmaps for the construction sector in the 23 connected cities within Viable Cities.
