1. DSP based Chromatic Dispersion Equalization and Carrier Phase Estimation in High Speed Coherent Optical Transmission Systems
Sammanfattning : Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. Using the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.

2. Fast-tunable resonators and quantum electrical circuits
Sammanfattning : In this thesis, measurements on superconducting electrical circuits that exhibit quantum mechanical effects are presented. Nonlinear superconducting circuits can be regarded as artificial atoms with energy spectra that can be engineered. The artificial atoms can be used as quantum bits for quantum computation. LÄS MER
3. Den ofrivilligt frivillige företagaren : Starta eget-bidragsföretagande och en förändrad livssituation
Sammanfattning : Avhandlingens syfte är att beskriva och analysera arbetets betydelse i starta eget–bidragsföretagares liv. Material har samlats in dels genom en omfattande enkätstudie som omfattar hela populationen nuvarande och tidigare företagare från 1995 i Östergötlands län, dels genom en serie livsberättelseorienterade intervjuer med ett urval aktiva respektive före detta företagare med fokus på deras inställning till arbete.

4. On the atmospheric transport pathways of heat into the Arctic in winter and spring
Sammanfattning : The atmospheric meridional energy transport is an important component in the global climate system, as it transports moisture and heat from the midlatitudes into the Arctic, balancing the regional energy loss to space. Narrow and intense injections of warm and moist air, so-called warm-air intrusions, have a large local imprint on the surface through various processes acting on different scales, such as cloud formation, turbulent fluxes and atmospheric large-scale circulation.

5. Förvandlingar i vikingatidens djurornamentik : Del 1 : En multiperspektivisk studie om figurknoppspännen av Birkatyp
Sammanfattning : During the past 150 years, different generations of scholars have been approaching Scandinavian Animal Art with queries that were as multifaceted as the materials that they studied. The focal point of this study are Birka type brooches, which are best likened to interactive sculptures that change shape as the viewer changes perspective. LÄS MER
