1. On technology implemention in product development : a process and approach
Sammanfattning : .... LÄS MER
2. A semiparametric estimator of the mean of heavy-tailed distributions
Sammanfattning : .... LÄS MER
3. Moment Estimation Using Extreme Value Methods
Sammanfattning : The thesis is composed of three papers, all dealing with the application of extreme value methods to the problem of moment estimation for heavy-tailed distributions. In Paper A, an asymptotically normally distributed estimate for the expected value of a positive random variable with infinite variance is introduced. LÄS MER
4. Properties of wave-front sets and non-tangential convergence
Sammanfattning : In this thesis we consider regularity properties for solutions to partial differential equations and pseudo-differential equations. The thesis mainly concerns wave-front sets and micro-local properties. LÄS MER
5. Propagation of singularities for pseudo-differential operators and generalized Schrödinger propagators
Sammanfattning : In this thesis we discuss different types of regularity for distributions which appear in the theory of pseudo-differential operators and partial differential equations. Partial differential equations often appear in science and technology. LÄS MER
