1. Dynamic higher order equations
Sammanfattning : The subject of this thesis is to derive and evaluate governing equations and correspondingboundary conditions for solid cylinders and rectangular plates, where the materialconstituting the cylinder or plate are governed by classical elasticity, micropolar elasticityor a functionally graded case of the previously mentioned models. This is achieved by asystematic power series expansion approach, by either adopting a generalized Hamilton'sprinciple or a direct approach. LÄS MER
2. Stakeholder Influence in Higher Education : Old Ideas in New Bottles?
Sammanfattning : This dissertation deals with how national higher education policy affects stakeholder influence in practice, i.e. how two selected higher education institutions, the University of Oslo and Telemark University College, have interpreted and adapted to national policy reforms. The aim of this dissertation is threefold. LÄS MER
3. Dynamic higher order equations for structural elements
Sammanfattning : The subject of this thesis is to derive and evaluate governing equations and corresponding boundary conditions for solid isotropic cylinders and isotropic micropolar rectangular plates. This is achieved by a systematic power series expansion approach, by either adopting a generalized Hamilton's principle or a direct approach. LÄS MER
4. Analysis and Design of Hybrid Control Systems
Sammanfattning : Different aspects of hybrid control systems are treated: analysis, simulation, design and implementation. A systematic methodology using extended Lyapunov theory for design of hybrid systems is developed. The methodology is based on conventional control designs in separate regions together with a switching strategy. LÄS MER
5. Periodic Structures with Higher Symmetries: Analysis and Applications
Sammanfattning : In this thesis, periodic structures with higher symmetries are studied. Their wave propagation characteristics are investigated and their potential applications are discussed. Higher-symmetric periodic structures are described with an additional geometrical operation beyond a translation operator. LÄS MER
