Smoothed Particle Hydrodynamics (SPH) is used to study the mechanisms of landslide-generated waves. As the landslide dynamics and the evaluation of impact forces acting on water are most important, landslide is modelled as a highly viscous fluid. Incompressible SPH (ISPH) is used for fluid simulation. Since the landslide is assumed as highly viscous fluid, it needs to satisfy the condition for the

Ship-generated waves were investigated in the Gota alv river, which is a major waterway on the Swedish west coast between the sea and Lake Vanern. Ships with a typical size of 85x15x5 m (lengthxwidthxdraft) travel at speeds between 5 and 10 knots, generating waves that cause sediment transport and erosion along the river bed and banks. Field measurements of the wave properties and turbidity were c

The grand challenges of contemporary fundamental physics-dark matter, dark energy, vacuum energy, inflation and early universe cosmology, singularities and the hierarchy problem-all involve gravity as a key component. And of all gravitational phenomena, black holes stand out in their elegant simplicity, while harbouring some of the most remarkable predictions of General Relativity: event horizons,

Accurate thermometry is essential for experiments in cryogenic environments, particularly those using dilution refrigeration to reach milli-Kelvin temperatures. In this thesis, the calibration range of a Cernox CX1050 sensor was extended below its nominal lower limit of 1.4 K. In addition, the response of RuOx sensors at different positions within the dilution refrigerator was examined to assess t

This paper investigates the aeroacoustic properties of dual-stream co-axial supersonic jets, focusing on sound generation at the engine nozzle exit, which significantly contributes to cabin noise in supersonic civil aviation. The study delves into three primary noise-generating mechanisms present in supersonic jets: broadband shock-associated noise, jet screech, and turbulent mixing noise. While s

A semiconductor-to-metal transition in N = 7 armchair graphene nanoribbons causes drastic changes in its electron and phonon system. By using angle-resolved photoemission spectroscopy of lithium-doped graphene nanoribbons, a quasiparticle band gap renormalization from 2.4 to 2.1 eV is observed. Reaching high doping levels (0.05 electrons per atom), it is found that the effective mass of the conduc
