1. Statistical Properties of Preliminary Test Estimators
Abstract : This thesis investigates the statistical properties of preliminary test estimators of linear models with normally distributed errors. Specifically, we derive exact expressions for the mean, variance and quadratic risk (i.e. the Mean Square Error) of estimators whose form are determined by the outcome of a statistical test.

2. Planned Change and Inertia : Integrating Technology, Organization and Human Aspects
Abstract : New work organization and new computer-based tools can save costs and improve quality. A fact that often is not acknowledged is that new work organization and new computer-based tools take resources from the organization.Three empirical studies were performed in production, concerning changed work organization and managerial innovation.

3. Modelling and analysis of multiphysical interactions in hydropower rotor systems
Abstract : In this thesis the objective is to develop rotordynamical models of hydropower units, where coupling between mechanical, electromagnetic and fluid dynamical system systems is of certain interest. Both fluid-rotor and electromechanical interactions are known to change the system coefficients of the rotor system, which affects eigenfrequencies, damping, stability and response. READ MORE

4. Nonlinear dynamics of flexible structures using corotational beam elements
Abstract : The purpose of this thesis is to develop corotational beam elements for the nonlinear dynamic analyse of flexible beam structures. Whereas corotational beam elements in statics are well documented, the derivation of a corotational dynamic formulation is still an issue. READ MORE

5. Corotational formulation for nonlinear analysis of flexible beam structures
Abstract : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. READ MORE
