1. Optimization of low-cost integration of wind and solar power in multi-node electricity systems: Mathematical modelling and dual solution approaches
Abstract : The global production of electricity contributes significantly to the release of CO2 emissions. Therefore, a transformation of the electricity system is of vital importance in order to restrict global warming. READ MORE

2. Optimization of process integration investments under energy market uncertainties
Abstract : The increased climate concern in society puts pressure on industries to decrease their energy use in different ways, and a number of studies show that there is a large potential for improved energy efficiency in the energy-intensive industry, for example through process integration. Uncertainties about future energy prices and policy instruments make it, however, difficult to evaluate and compare different kinds of energy-saving measures with respect to net present value as well as reduction of CO2 emissions.

3. High order summation-by-parts based approximations for discontinuous and nonlinear problems
Abstract : Numerical approximations using high order finite differences on summation-byparts (SBP) form are investigated for discontinuous and fully nonlinear systems of partial differential equations. Stability and conservation properties of the approximations are obtained through a weak imposition of interface and boundary conditions with the simultaneous-approximation-term (SAT) technique.

4. Optimization of Investments for Strategic Process Integration and Pulp Mill Biorefinery Projects under Uncertainty
Abstract : Energy-intensive industrial plants operate in a changing, uncertain environment. Long-term changes are expected in energy prices, political regulations and technology development. Pulp and paper companies, like many other industries, are under strong pressure to respond to these changes. READ MORE

5. Symplectic methods for isospectral flows and 2D ideal hydrodynamics
Abstract : The numerical solution of non-canonical Hamiltonian systems is an active and still growing field of research. At the present time, the biggest challenges concern the realization of structure preserving algorithms for differential equations on infinite dimensional manifolds. READ MORE
