2. Variation simulation of sheet metal assemblies for geometrical quality : parameter modeling and analysis
Sammanfattning : The automotive industry deals with an increased demand for virtual verification of the geometrical quality of the product. The aim is to reduce the need for adjusting the assembly process to deliver a product with high quality. LÄS MER
Sammanfattning : This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such process there is a parameter, known as the intensity, governing its behavior. LÄS MER
Sammanfattning : This thesis consists of five essays exploring the validity of some extensively used financial models with a focus on the Swedish equity and derivative markets. The essays are of both an empirical and a theoretical nature. LÄS MER
Sammanfattning : In this thesis, two aspects of string theory are discussed, tensionless strings and supersymmetric sigma models.The equivalent to a massless particle in string theory is a tensionless string. Even almost 30 years after it was first mentioned, it is still quite poorly understood. LÄS MER
