  1. 1. Humidity dependent conductivity of air in HVDC applications and the role of surfaces

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets fysik

    Författare :Erik Svensson; [2023]
    Nyckelord :HVDC; humidity; air conductivity; thin films; HVDC; luftfuktighet; luftkonduktivitet; tunna filmer;

    Sammanfattning : High Voltage Direct Current (HVDC) bushings are insulated devices designed to facilitate the safe passage of electric current across an earthed barrier. Understanding air conductivity is of utmost importance in the design of HVDC components, which is determined by ion density and ion mobility. LÄS MER

  3. 2. Impact of Extreme River Flows on Bridges An Application to River Lagan in Ljungby Municipality, Sweden Using HEC RAS

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Assad Mohammad Tahir; [2022]
    Nyckelord :HEC RAS; Extreme River Flow; River Bridges; Ljungby; Lagan; Climate Change.; Technology and Engineering;

    Sammanfattning : The role of bridges in the transportation network has become increasingly important as they ensure the smooth and safe passage of people and goods across rivers and other bodies of water. Flowing water impacts bridges over rivers primarily in two ways: (1) Hydrodynamic forces that directly impact the structure and (2) scouring at the pier and abutment, including contraction scour.

  4. 3. Modernized 6 and 10-ton Dock Levelers

    Master-uppsats, Lunds universitet/Innovation

    Författare :Viola Nilsson; Rebecka Karlsson; [2021]
    Nyckelord :Dock leveler; FEM; stress; sheet metal; load case; Technology and Engineering;

    Sammanfattning : This Master Thesis is made in collaboration with ASSA ABLOY Entrance Systems and addresses the issues and problem areas of two dock leveler models; 60 kN and 100 kN to find a new improved design. After the following product development process, a new concept was created which could withstand applied forces exceedingly. LÄS MER

  5. 4. HÄLJARPS LYCKOR : ett stationsnära boende

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

    Författare :Anette Andersson; [2021]
    Nyckelord :järnvägsstation; stationsnära planering; hållbar bebyggelse; utvecklingsområde; Häljarp; stationsort;

    Sammanfattning : Idag reser vi allt mer och allt längre både privat och till vardags. Vårt utökade geografiska rörelsemönster har minskat antalet lokala arbetsmarknader. En allt mer sammankopplad region ger möjlighet för människor att bo i den mindre orten men ändå ha tillgång till flera arbetsmarknader i olika kommuner. LÄS MER

  7. 5. Towards a Safer Bromsten : A study of security enhancing and crime preventive measures in the planning of Bromstensstaden

    M1-uppsats, KTH/Byggteknik och design
