1. 1. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Vilma Nordh; [2024]
   Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

   Abstract : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

3. 2. Evaluating the performance of cone crushers under various feeding conditions using DEM and coupled DEM-MBS simulations

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : John Larsson; [2023]
   Keywords : Discrete Element Method; DEM; Cone Crusher; Segregation; Co-Simulation; Multi-body Dynamics; MBD;

   Abstract : Cone crushers are used in both the construction and mining industries for the production of aggregates and extraction of ores. Aggregates are used when building for example houses, roads and railways, hence the cone crushers are a vital part of modern society. READ MORE

4. 3. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges

   University essay from Luleå tekniska universitet/Byggkonstruktion och brand

   Author : Alex Eriksson; [2023]
   Keywords : Concrete; numerical analysis; trough bridge; railway bridge; finite element model; discrete element method; Betong; numeriskanalys; trågbro; tågbro; finita elementmetoden; diskreta elementmetoden;

   Abstract : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

5. 4. Modulation of the optical properties of quantum dots by surface acoustic waves

   University essay from KTH/Tillämpad fysik

   Author : Tanguy Schetelat; [2023]
   Keywords : Nanophotonics; Quantum dots; Surface acoustic waves; Interdigital tansducers; Optomechanical coupling; Nanofotonik; Kvantprickar; Akustika yt-vågor; Interdigital tansducers; Optomekanisk koppling;

   Abstract : Semiconductor quantum dots (QDs) are considered to be a crucial part of future quantum technologies due to their enormous potential as efficient sources of single and indistinguishable photons. Single photons are necessary to transport quantum information over large distances through the existing global fibre optic network. READ MORE

6. 5. Applying spatially and temporally adaptive techniques for faster DEM-based snow simulation

   University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

   Author : Simon Andreasson; Linus Östergaard; [2023]
   Keywords : Real-time simulation; DEM; GPU; Games; Computer graphics; Realtidssimulering; DEM; GPU; Spel; Datorgrafik;

   Abstract : Background. Physically-based snow simulation is computationally expensive and not yet applicable to real-time applications. Some of the prime factors for this cost are the complex physics, the large number of particles, and the small time step required for a high-quality and stable simulation. READ MORE
