  1. 6. The differential signalling of the succinate receptor SUCNR1/GPR91, through Gi versus Gq

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Sofie Liljewall; [2022]
    Nyckelord :GPR91; SUCNR1; G protein recruitment; Gi; Gq; TRUPATH biosensor; BRET2; Applied Microbiology; Biology and Life Sciences;

    Sammanfattning : G protein-coupled receptors are the biggest family of membrane bound receptor in the human genome, they are also target for many drugs due to their accessible location in the cell membrane. We have characterized the G protein recruitment of the succinate receptor 1 (SUCNR1/GPR91). LÄS MER

  3. 7. Non-Linear strain paths in Sheet Metal Forming

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Anton Eriksson; [2021]
    Nyckelord :Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Sammanfattning : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. LÄS MER

  4. 8. Models of the Universe : An analysis of the asymptotic behaviour of non-linear dynamical systems

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Noa Vikman; Gustav Romare; [2021]
    Nyckelord :;

    Sammanfattning : In this thesis we present some relevant theory, and then we rigorously investigate the existence intervals and the asymptotic behaviors of three cosmological models. The first model we investigate is based on the Friedmann-Lemaître-Robertson-Walker (FLRW) metric, which is consistent with the cosmological principle. LÄS MER

  5. 9. Implied volatility with HJM–type Stochastic Volatility model

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

    Författare :Thi Diu Cap; [2021]
    Nyckelord :Implied volatility surface; stochastic volatility model; HJM framework;

    Sammanfattning : In this thesis, we propose a new and simple approach of extending the single-factor Heston stochastic volatility model to a more flexible one in solving option pricing problems.  In this approach, the volatility process for the underlying asset dynamics depends on the time to maturity of the option.

  7. 10. Evaluating the suitability of Gaussian process regression and XGBoost on electricity price forcasting

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Owen Liu; [2021]
    Nyckelord :Power Markets; Seasonality; Electricity Spot Price; Gaussian Process Regression; XGBoost; Mathematics and Statistics;

    Sammanfattning : Electricity finds itself different from other fresh-ware commodities, it cannot easily be stored. This characteristic trait of electricity results in traditional pricing methods not working for electricity pricing. Thus different pricing schemes are needed, such as Price Forward Curves (PFC) or pricing against a price level. LÄS MER
