This report presents lessons learned from twenty-five worldwide real-life case studies implementing the integration of daylighting and electric lighting. The case studies were monitored with respect to energy use for lighting, visual performance, non-visual performance, and users’ satisfaction. The monitoring is largely based on field measurements, but it is also complemented with simulations and
This thesis investigates growth of III – V semiconductor nanowire (NW) arrays, in a core- branch architecture, with the aim to develop diffusion driven light emitting diodes (LED) on NWs. Diffusion driven LEDs are based on the concept of decoupling the active region from the p-n junction. The carriers are injected by diffusion in the active region, because of the bandgap difference between the pn
The stability of relaxation techniques has been studied for strongly coupled fluid-structure interaction (FSI) with application to a cantilever immersed in channel flow. The fluid is governed by Navier–Stokes equations for incompressible flow condition using turbulence modeling, and the solid is governed by the equation of motion with compressible material modeling. The applied kinematic descripti
A fluid–structure interaction (FSI) technique is applied to study the influence of hydrodynamic damping on the motion of a cantilever in a still tank. The FSI is performed by a partitioned technique, using the deal.II and OpenFOAM open-source packages. An incompressible flow solver is applied for the fluid and a compressible solver for the structure. The motion of the structure is generated by app
The valence excited states and the 3s, 3p, and 3d (united atom) Rydberg states of benzene and phenol have been obtained by the CASPT2 method, which computes a second-order perturbation correction to complete active space self-consistent field (CASSCF) energies. All non-zero dipole oscillator strengths are also computed, at the CASSCF level. For benzene, 16 singlet and 16 triplet states with ex
The electronic excitation spectra of pyridine and phosphabenzene have been studied using theoretical methods. The electronic states are described by wave functions derived from second-order perturbation theory based on multiconfigurational reference functions. The study includes singlet and triplet valences excited states as well as a number of Rydberg states. For both molecules the transition
Against the backdrop of strong local self-government, this article analyses how local autonomy in Sweden has been affected by the implementation of the European Social Fund (ESF) and the ‘partnership principle’.
