  1. 1. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hannah Wik; [2023]
    Nyckelord :Space; Space Plasma Physics; Collisionless Shocks; MMS; Non-stationarity; Shock Reformation; Rippling; Bow Shock; Solar Wind; Rymd; Rymdfysik; Kollisionsfria chocker; MMS; Icke-stationär; Reformation; Bogchock; Solvind;

    Sammanfattning : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. LÄS MER

  3. 2. An Interest Rate Benumbed : Evidence from a structural VAR; can a structural break be found in recent monetary policy transmission?

    Kandidat-uppsats, Uppsala universitet/Nationalekonomiska institutionen

    Författare :Johan Modin; [2019]
    Nyckelord :monetary policy; vector autoregression; SVAR; nonstationarity; structural break;

    Sammanfattning : The reliability of monetary policy as an economic stabilisation tool depends on the understanding of the empirical effects of policy intervention on macroeconomic aggregates. Since investigating the interdependencies between macroeconomic variables necessarily involves studying their interactions over time, time series analysis is an important tool. LÄS MER
