   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

3. 17. Parametrization of a Lithium-ion battery

   University essay from KTH/Kemiteknik

   Author : Elsa Arksand; [2021]
   Keywords : Parametrization; LiFePO4; Single particle model; Li-ion battery; Pseudo-OCV; Parametrisering; LiFePO4; Singlepartikelmodell; Litiumjonbatteri; Pseudo-OCV;

   Abstract : Batterimodeller används för att representera batterier. För ändamål som batterihanteringssystem används idag främst empiriska modeller som representerar ett batteri med en motsvarande kretsmodell. Några nackdelar för dessa modeller ligger i dess oförmåga att simulera interna tillstånd och en tidskrävande parametriseringsprocess. READ MORE

4. 18. Towards Automatic and Systematic Compressor Model Selection Based on Measurement Data
