1. 1. Deep-Decarbonization of the Industrial Sector through Electrification in France : Analysis of Current Status, Technologies and Policies

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Alexandra Couchy; [2023]
   Keywords : ;

   Abstract : The increasing scientific awareness around man’s responsibility towards global warming has led to political decisions and actions, in order to try to curb the phenomenon of climate change. As a pioneer in tackling greenhouse gases emissions, Europe is committed to achieving carbon neutrality by 2050, with emission reduction targets of -55% by 2030, and Member States have had to make plans to fulfil this goal.

3. 2. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

   University essay from KTH/Hållfasthetslära

   Author : Ludvig Dahlin; Ebba Larsson Regnström; [2022]
   Keywords : FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

   Abstract : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

4. 3. Development of a Simulation Model for Combined PVT and Ground Source Heat Pump Systems : A TRNSYS Model Created for Commercial Use

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : HANNA OLAUSSON; EMMA WERNIUS; [2021]
   Keywords : Electrify everything; Solar assisted heat pump; Solar Energy; TRNSYS; Elektrifiera allt; solassisterad värmepump; Solenergi; TRNSYS;

   Abstract : The Swedish government has set a target of a 100% renewable electricity system by 2040. To reach this goal, many actions have to be undertaken. Electrification of buildings is one action to be undertaken as the residential sector accounts for a large share of greenhouse gas emissions, where the most energy efficient method is to use heat pumps.

5. 4. Finite Element Analysis of Stresses in the MIST CubeSat due to Dynamic Loads During Launch

   University essay from KTH/Lättkonstruktioner

   Author : Carl Järmyr Eriksson; [2021]
   Keywords : Satellite; CubeSat; Nanosatellite; Dynamic Loads; Launch Loads; Finite Element Analysis; FEA; Quasi-static Acceleration; Modal Analysis; Random Vibration; Shock Loads; satellit; CubeSat; nanosatellit; dynamiska laster; uppskjutningslaster; finita elementmetoden; FEM; kvasistatisk acceleration; modalanalys; stokastiska vibrationer; chocklaster;

   Abstract : A finite element model of the CubeSat MIST was created, in order to assess the stresses that occur in the satellite in response to loads during its launch. Due to size limits of thesoftware used, simplifications had to be made to the geometry of the model. READ MORE
