  1. 1. Practice variation in sepsis management in the eICU database

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Kemiteknik (CI)

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Johannes Ekman; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Ann-Sofi Lenander; [2021]
    Keywords : 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;

    Abstract : 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.

  6. 5. Modelling the water balance of a grassland soil

    University essay from SLU/Dept. of Soil and Environment

    Author : Elvin Rufullayev; [2020]
    Keywords : calibration; high precision weighing lysimeter; numerical modelling; plant growth; potential evapotranspiration; soil processes; STELLA Architect; temperate grassland; TERENO; vadose zone; validation;

    Abstract : Expected future climate change characterized by higher temperatures and more frequent summer droughts may cause significant changes in soil hydrological processes leading to limited nutrient and water availability and reductions in plant growth. Soil hydrological and plant growth models attempt to reproduce the complex interactions in the plant-soil water system in terms of mathematical equations, parameters and coefficients. READ MORE
