Assessing Holocene and late Pleistocene geomagnetic dipole field variability
Palaeomagnetic studies of continuous geological archives and archaeological artefacts are required to reconstruct geomagnetic field changes beyond the range of historical observations. In this thesis I assess the reliability of sedimentary palaeomagnetic data and Holocene dipole field …

Simulationen hydrologischer Massenvariationen und deren Einfluss auf die Erdrotation
Die gestiegene Messgenauigkeit der Erdrotationsparameter ermöglicht inzwischen eine Berücksichtigung von Sekundäreffekten, wie Einflüssen hydrologischer Massenvariationen. Variationen der Erdrotation durch hydrologische Massenvariationen sind bisher weniger gut als atmosphärische und ozeanische …

Developing a solar resource map for a stored solar cooker
… there is no radiation from the sun. The ability of the stored solar cooker to collect heat depends on the ambient conditions (solar radiation, percent cloud cover, temperature, and wind speed). Solar resource maps can quantify the global potential for solar energy use, but existing maps do not …

A comprehensive study of the 26th December 2004 Sumatra earthquake: possible implications on Earth rotation and investigations on the coseismic and postseismic stress diffusion associated with the seismic rupture
In this work a multidisciplinary study of the December 26th, 2004 Sumatra earthquake has been carried out. We have investigated both the effect of the earthquake on the Earth rotation and the stress field variations associated with the seismic event. In the first part of the work we have quantified …

Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle
This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated. Vigorous discussion has surrounded these phenomena since they were …

Greenhouse climate model : an aid to estimate the influence of supplemental lighting on greenhouse climate
GeoGreenhouse project involves the construction of a greenhouse for growing tomatoes in Iceland. The first stage consists of a gross area of five hectares. Due to the peculiarities of such project and because of the unique weather, a greenhouse climate model is advisable to analyze various design …
