  1. 1. Numerisk modellering av tvåfasströmning och syretransport i bubbelkolumner : Metodutveckling för att förutsäga syretransportshastigheten i rent vatten och surfaktantlösningar

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Fredrik Andersson; [2022]
    Nyckelord :Bubbelströmning; bottenluftning; syresättning; surfaktanter; computational fluid dynamics;

    Sammanfattning : I samband med det globala samhällets ökande populationsmängd och ekonomiska utveckling ökar färskvattenkonsumtionen och mängden avloppsvatten som produceras. Avloppsvatten behöver renas innan det släpps ut för att inte påverka miljön negativt. LÄS MER

  3. 2. Practice variation in sepsis management in the eICU database

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Nils Nordmark; Patrick Royer; [2021-12-17]
    Nyckelord :sepsis; calibration; practice variation; importance sampling; multiple imputation;

    Sammanfattning : Sepsis is a life-threatening syndrome triggered by an infection. Despite international guidelines, sepsis management varies between sites. This unwanted practice variation may affect negatively the quality of care but enables theoretically retrospective studies for finding optimal treatment strategies. LÄS MER

  4. 3. A Nonlinear Reservoir Model to Simulate Blue-Green Stormwater Systems – An Application to Augustenborg Catchment in Malmö, Sweden

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Emmanuel Ekwu; [2021]
    Nyckelord :Blue-green stormwater control; Nonlinear reservoir routing model; Stormwater; Modelling; Calibration; Water engineering; Technology and Engineering;

    Sammanfattning : The increasingly rapid urbanization has led to vast impervious surface areas in the urban environment. This situation of impervious surfaces has increased the surface temperature and interrupted the natural water circle, which has negatively impacted the urban environment. LÄS MER

  5. 4. Modeling The Temperature of a Calorimeter at Clab : Considering a Thermodynamic Model of The Temperature Evolution of The Calorimeter System 251

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Johannes Ekman; [2021]
    Nyckelord :calorimetry; calorimeter; System 251; temperature evolution; spent nuclear fuel; SNF; MATLAB; SERPENT2; Clab; nuclear decay heat; calibration measurements; thermodynamic model; gamma escape fraction; mass correction; calibration measurements; electric heater; three component system; system of ordinary differential equations; eigenvalues; eigenvalue estimation; temperature increase method; polynomial approximation of mass correction; sensitivity of mass correction; calorimeter heat capacity; mass correction uncertainty; calorimeter calibration curve; monoenergetic gamma spectrum; curve fitting of temperature as function of time;

    Sammanfattning : It is important to know the heat generated due to nuclear decay in the final repository for spent nuclear fuel. In Sweden, the heating powers generated in spent nuclear fuels are currently measured in the calorimeter System 251 at the Clab facility, Oskarshamn. LÄS MER

  7. 5. A GIS-Based Method of Deriving Spatially Distributed Unit Hydrographs

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Ann-Sofi Lenander; [2021]
    Nyckelord :the unit hydrograph; GIS; ArcPy; design storm; SCS-CN method; spatial data; excess rainfall; enhetshydrografen; GIS; Arcpy; design regn; SCS-CN metoden; geodata; effektivt regn;

    Sammanfattning : Prior to using hydraulic and spatially distributed modelling softwares, the theory of the unit hydrograph was a commonly used tool for modelling of surface and runoff water. While distributed models often provide detailed results from extensive calculation durations, the unit hydrograph have been questioned for simplifying the physical characteristics of the watershed modelled.
