16. Studies on aquaporin 4 : a molecular determinant of brain water homeostasis
Sammanfattning : A well controlled brain water homeostasis is of utmost importance for an appropriate control of neuronal activity. Astrocytes express the water channel aqauporin 4 (AQP4) and play a key role for the maintenance of brain water homeostasis. Brain edema is a result of perturbed water homeostasis and involves astrocyte swelling. LÄS MER

18. Extreme points of the Vandermonde determinant and phenomenological modelling with power exponential functions
Sammanfattning : This thesis discusses two topics, finding the extreme points of the Vandermonde determinant on various surfaces and phenomenological modelling using power-exponential functions. The relation between these two problems is that they are both related to methods for curve-fitting. LÄS MER
19. Quasi-subscribers in the Swedish Mobile Phone Market: The Phenomenon and Determinant Factors
Sammanfattning : This thesis investigates the problematic inaccuracies of mobile phone density as a measure on access and use of mobile phones. The inaccuracies are presumably caused by the presence of quasi-subscribers - mobile phone users with multiple active SIM cards or subscriptions - that exaggerate the actual number of mobile phone users.

20. Extreme points of the Vandermonde determinant in numerical approximation, random matrix theory and financial mathematics
Sammanfattning : This thesis discusses the extreme points of the Vandermonde determinant on various surfaces, their applications in numerical approximation, random matrix theory and financial mathematics. Some mathematical models that employ these extreme points such as curve fitting, data smoothing, experimental design, electrostatics, risk control in finance and method for finding the extreme points on certain surfaces are demonstrated.
