1. There and back again... An Earth magneto-tale : understanding plasma flows in the magnetotail
Sammanfattning : On average, the Earth's magnetotail plasma sheet seems to be a calm region of the magnetosphere where the plasma moves slowly towards Earth. However, the plasma sheet actually hosts many phenomena, some of which can affect Earth. LÄS MER
2. Escape to space or return to venus : ion flows measured by venus express
Sammanfattning : The present-day Venusian atmosphere is crushingly dense, extremely hot and arid. Yet, in its early history, Venus presumably had a massive amount of water, which, if spread evenly over the surface, provided a water depth of 10s to 100s of meters. Therefore, over the course of the atmospheric evolution, the water must have been removed from Venus. LÄS MER
3. Microsystem Interfaces for Space
Sammanfattning : Microsystem interfaces to the macroscopic surroundings and within the microsystems themselves are formidable challenges that this thesis makes an effort to overcome, specifically for enabling a spacecraft based entirely on microsystems. The NanoSpace-1 nanospacecraft is a full-fledged satellite design with mass below 10 kg. LÄS MER
4. Stadens gränsplatser : Kungliga Poliskammaren och vardagens omstridda rum i Stockholm, 1776–1835
Sammanfattning : This dissertation explores the interaction between the inhabitants of Stockholm and the constables of the Royal Police Chamber—Sweden’s first police force—during a period in the city’s history that is associated with stagnation from the perspectives of demography and economy. The aim is to understand how space was negotiated and changed over time through everyday interactions and practices. LÄS MER
5. Optimisation and control of shear flows
Sammanfattning : Transition to turbulence and flow control are studied by means of numerical simulations for different simple shear flows. Linear and non-linear optimisation methods using the Lagrange multiplier technique are employed. LÄS MER
