1. 11. The parametrisation of cross sections for Dark Matter particle processes

   University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

   Author : Conrad Schwanitz; [2017]
   Keywords : Physics and Astronomy;

   Abstract : Experiments at particle colliders provide experimental verifications of theories in particle physics, and allow to search for new particles. Computer programs are used to simulate particle collisions. Those so-called event generators can be used to prove theories and compare their results to actual collisions from the colliders.

3. 12. Spacecraft dynamic analysis and correlation with test results : Shock environment analysis of LISA Pathfinder at VESTA test bed

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Beata Iwona Kunicka; [2017]
   Keywords : FEA FEM; finite element analysis; finite element method; mechanical analysis; structural analysis; dynamic analysis; computational dynamic analysis of structures; shock analysis; shock environment; shock test; shock test campaign; spacecraft dynamic analysis; MSC Nastran; MSC Patran; Dynaworks; Shock Response Spectrum; SRS; space engineering; space science and technology; mechanical engineering; structural engineering; analysis optimisation; analysis parametrisation; mechanical wave propagation; shock propagation; damping; hysteretic damping; viscous damping; structural damping;

   Abstract : The particular study case in this thesis is the shock test performed on the LISA Pathfinder satellite conducted in a laboratory environment on a dedicated test bed: Vega Shock Test Apparatus (VESTA). This test is considered fully representative to study shock levels produced by fairing jettisoning event at Vega Launcher Vehicle, which induces high shock loads towards the satellite. READ MORE

4. 13. Modelling global Gross Primary Production using the correlation between key leaf traits

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Alexandra Pongrácz; [2017]
   Keywords : ecosystem modelling; leaf longevity; leaf nitrogen content; leaf mass per area; LEIA; LPJ-GUESS; GPP; terrestrial biosphere; Earth and Environmental Sciences; Biology and Life Sciences;

   Abstract : Sophisticated ecosystem models make it possible to evaluate the potential future changes of the carbon sequestration capacity of the terrestrial biosphere, as a response to the rapid environmental and climatic changes. Accuracy of model estimates is however strongly dependent on the parametrisation of driving parameters. READ MORE

5. 14. Static Multi-Versioning for Efficient Prefetching

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Per Ekemark; [2016]
   Keywords : ;

   Abstract : Energy efficiency is one of the biggest challenges in modern computer architecture. Increased performance and improved energy efficiency is always in demand whether it is for battery longevity in mobile applications or thermal limits in high-performance computing. To reach the best result, hardware and software must compliment each other. READ MORE

6. 15. Development of a Vehicle Simulation Model Consisting of Low and High Frequency Dynamics

   University essay from Linköpings universitet/Fordonssystem

   Author : Dennis Belousov; [2016]
   Keywords : Vehicle dynamics; simulation model; parameter estimation; road profile characteristics; power spectral density;

   Abstract : As vehicle testing on existing vehicles is both time and resource consuming, the work of testing safety algorithms on vehicle is desired to be made more efficient. Therefore the goal of this thesis is to study and develop a vehicle simulation model that can simulate desired dynamics of existing and non-existing vehicles. READ MORE
