  1. 1. Stokastisk modellering och prognosticering inom livförsäkring : En dödlighetsundersökning på Länsförsäkringar Livs bestånd

    Master-uppsats, Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Henrik Andersson; Robin Bakke Cato; [2023]
    Nyckelord :Mortality Lee-Carter Makeham Gompertz Hull-White Short-rate Model Feller; Dödlighet dödlighetsundersökning Lee-Carter korträntemodeller Hull-White Makeham dödlighetsintensitet DUS Svensk Försäkring Feller;

    Sammanfattning : Studier av livslängder och dödssannolikheter är avgörande för livförsäkring. Betalningar gällande livförsäkringar är helt beroende av om en individ lever eller ej, eller befinner sig i olika hälsotillstånd. LÄS MER

  3. 2. Explorative Scenarios for Future Lithium Supplies and Demand

    Magister-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Aksel Rahman; [2023]
    Nyckelord :lithium mining; lithium future production; Gompertz models; Richards models; Logistic models;

    Sammanfattning : Because of its specific qualities, lithium is a key element for making lithium-ion batteries, which is of great relevance since the battery sector is the fastest growing user of lithium to date and with the transition towards a fully electrified transportation sector due to the current climate agenda and an even bigger increase in demand for lithium is anticipated for the coming decades. The two main sources for lithium to date are mines and brines, with brine water composing around 87 % of the world’s lithium reserves in terms of contained lithium. LÄS MER

  4. 3. Projections of future lithium production and implications for EU

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Wang Lei; [2021]
    Nyckelord :;

    Sammanfattning : Lithium-ion batteries (LIBs) are critical for the adoption of electrical vehicles vital for the electrification of road traffic as part of our fossil-fuel phasing out plan. This increasing demand for energy storage has expanded lithium production ten folds over the last 10 years and led to a new debate on the availability of lithium resources as well as sustainable challenges in resource exporting countries.

  5. 4. Comparison of mortality rate models for current health diseases

    Master-uppsats, Mälardalens högskola/Akademin för utbildning, kultur och kommunikation

    Författare :Iván Araque Cristóbal; [2020]
    Nyckelord :Diseases; model; mortality rate; influenza; respiratory problems; Power-exponential; Gompertz; pollution; least squares method;

    Sammanfattning : In this research, we compare different models, that are used to model the mortality rate curve, to model different deaths caused by certain diseases. In this comparison we increase the complexity of the models, starting with the Gompertz model, to later reduce the complexity fixing some parameters depending on the error. .. LÄS MER

  7. 5. The effect on mortality of having a Chief Executive Officer position: An analysis of Swedish data from 1997-2009

    C-uppsats, Handelshögskolan i Stockholm/Institutionen för finansiell ekonomi

    Författare :Anna Norrevik; Lennart Wang; [2013]
    Nyckelord :CEO; hazard ratio; life expectancy; mortality; survival analysis;

    Sammanfattning : In this thesis, data on 203 702 CEOs in Sweden from the time period 1997 to 2009 is combined with death data and company information to compare CEOs' mortality between different groups. This study compares survival analysis results using Cox, Gompertz and GEE-logistic parametric models. LÄS MER
