2. Solar Wind and Geomagnetic Activity - Predictions Using Neural Networks
Abstract : This thesis shows how artificial neural networks (ANNs) can be applied to predict geomagnetic activity from solar-wind data. It introduces and summarizes five papers where development of ANN models are reported, and where predictions of geomagnetic activity are discussed. READ MORE

4. Space Weather Physics: Dynamic Neural Network Studies of Solar Wind-Magnetosphere Coupling
Abstract : This thesis presents studies of solar wind-magnetosphere coupling using dynamic neural networks in combination with statistically correlative analysis. The primary contribution of the thesis is dynamic neural network models that can be implemented for near real-time predictions of geomagnetic storms from the solar wind alone. READ MORE

5. Disentangling production and climate signals from high-resolution Beryllium records: implications for solar and geomagnetic reconstructions
Abstract : The sun is the most important energy source for the Earth’s climate system, however, influences of solar variations on climate are not fully understood. Studying past solar activity can improve our understanding of what role the sun plays in Earth’s climate. READ MORE
