1. Molecular Quadratic Response Properties with Inclusion of Relativity
University dissertation from Institutionen för fysik, kemi och biologiAbstract : This thesis concerns quadratic response properties and their application to properties in Jablonski diagrams such as resonant two-photon absorption and excited state absorption. Our main interest lies in optical power limiting applications, and in this context, molecules containing heavy metal atoms prove superior. READ MORE

2. Gradient Corrections to Exchange Energies within Density Functional Theory
University dissertation from Per-Sverre Svendsen, Dept. of Theoretical Physics, Solvegata 14 A, 22362 LUNDAbstract : The small-wavector expansions for the first- and second-order exchange energy kernels (second-and third-order functional density derivatives of the exchange energy) have been investigated. Expansion coefficients are found, both in the case of a statically screened Coulomb interaction and a 'bare' interaction. READ MORE

3. Thermal response test : method development and evaluation
University dissertation from Luleå : Luleå tekniska universitetAbstract : Since the first introduction of thermal response tests with mobile measurement devices in Sweden and USA in 1995, the method has developed and spread in North America and Europe. Thermal response tests have so far been used primarily for in situ determination of design data for BHE (borehole heat exchanger) systems, but also for evaluation of grout material, heat exchanger types and groundwater effects.

4. Partial Response and Faster-than-Nyquist Signaling
University dissertation from Department of Electrical and Information TechnologyAbstract : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. READ MORE

5. Electronicharacterization of molecules with application to organic light emitting diodes
University dissertation from Kista : Tillämpad InformationsteknikAbstract : The presented thesis is devoted to the field of organic light emittingdiodes (OLEDs). Time-dependent Kohn-Sham density functional theory(TDDFT) is appliedin order to eludicate optical properties such as fluorescence andphosphorescence for some of the most important materials. READ MORE
