This thesis presents work in several areas relating to Random Matrix Theory and Elasticity. It contains 4 papers presenting work on different issues. Paper I concerns correlations between eigenvalues in random matrices of real symmetric (GOE) or quaternion real (GSE) form. It presents a calculation showing that correlations between arbitrarily many eigenvalues can be obtained from averages of a t
The aim of the present thesis was to study temperament traits and their relationships to psychiatric diagnoses, suicidal behavior and a number of biological measures in a sample of hospitalized suicide attempters. The subjects showed a bimodal distribution on the Validity scale from the Marke-Nyman Temperament (MNT) inventory, with a large subgroup showing low Validity. Cluster analyses of the sc
This contribution comprises a comparison of capacity performances of MIMO terminal antenna configurations for smart phones at 2.65 GHz, measured in an extensive 2×2 MIMO measurement campaign in noise- and interference-limited urban environments. Whereas, on average along the route, the performances where dictated by the received power, locally the eigenvalue dispersion of the communication channel
Abstract. A well known trade-off effect with modelling is that when it is user friendly it becomes ambiguous and when it has a formal notation, that makes it unambiguous, it becomes less user friendly. A well known solution to this dilemma is to use models on various levels of formalism where the least formalized models are known to be more user friendly and the most formalized models are well sui

In the Southern Gas Basin (SGB) of the North Sea there are many mature gas fields where time-lapse monitoring could be very beneficial in extending production life. However, the conditions are not immediately attractive for time-lapse seismic assessment. This is primarily because the main production effect to be assessed is a pore pressure reduction and frame stiffening because of gas production i
