  1. 1. Censoring Bias in Oncology Clinical Trials

    Kandidat-uppsats, Lunds universitet/Matematisk statistik

    Författare :Andrea Mattsson; [2020]
    Nyckelord :survival analysis; censoring; progression-free survival; Cox proportional hazards model; oncology clinical trial; HER2CLIMB; Mathematics and Statistics;

    Sammanfattning : Time to disease progression or death (PFS) is of main interest in oncology clinical trials. The data is commonly analyzed using a Cox model. Early discontinuation gives uncertainty in the estimated hazard ratio (HR). Censoring is generally used to handle discontinuations. LÄS MER

  2. 2. Ventilation i höga trapphus vid händelse av brand

    Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet; Lunds universitet/Riskhantering (CI)

    Författare :Jill Gullberg; [2016]
    Nyckelord :PFS; pressurization; stairwells; ventilation; Övertrycksättning; Trapphus; ventilation.; Technology and Engineering;

    Sammanfattning : This thesis investigates possible problems due to pressurization of high staircases. The main problem arising when high enclosures are not pressurized in sections in the event of fire is that an imbalance of the pressure profile in the building occurs. LÄS MER

  3. 3. Formulation of the power flow problem in human readable form for translation into an efficient solver

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Muhammad Talal Khan; [2016]
    Nyckelord :;

    Sammanfattning : Power systems are complex systems that need supervision and control to operatereliably and safely. Energy Management Systems (EMS)/SCADA provides the necessary aids formonitoring and control of power systems. Since power ow forms the basis of power system analysis,power ow solvers (PFS) are an integral part of EMS/SCADA systems. LÄS MER

  4. 4. A study of shock-metamorphic features in zircon from the Siljan impact structure, Sweden

    Kandidat-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Josefin Martell; [2016]
    Nyckelord :Zircon; impacts; shock metamorphism; shock metamorphic features; planar deformation features; Siljan impact structure; Earth and Environmental Sciences;

    Sammanfattning : Shock-metamorphic features such as planar deformation features (PDFs) and in some cases planar fractures (PFs) are widely used as impact-indicators when to confirm a suspected impact structure. These features only develop when exposed to a sudden and immense pressure and temperature increase in association with meteorite impacts. LÄS MER

  5. 5. Brandteknisk riskvärdering av Västralid äldreboende i Olofström

    L3-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Fabian Ardin; Gustaf Berglund; Andreas Håkansson; Martin Thomasson; [2015]
    Nyckelord :Fire safety evaluation; nursing home; assisted egress; evacuation; fire; FDS; PFS; fire protection for ventilation systems; elevator shaft; stack effect; Brandteknisk riskvärdering; Västralid; Olofström; äldreboende; assisterad utrymning; brand; ventilationsbrandskydd; hisschakt; skorstenseffekt; Technology and Engineering;

    Sammanfattning : This report is a fire safety evaluation of Västralid nursing home in Olofström. The object consist of three connected housing bodies, first built in the 1970’s. At first, the buildings were used as regular apartments, but they were converted into nursing apartments for elderly people in the 1990’s. LÄS MER
