6. On the Surface of Conducting Polymers : Electrochemical Switching of Color and Wettability in Conjugated Polymer Devices
Sammanfattning : Since the discovery in 1977 that conjugated polymers can be doped to achieve almost metallic electronic conduction, the research field of conducting polymers has escalated, with applications such as light emitting diodes, solar cells, thin film transistors, electrochemical transistors, logic circuits and sensors. The materials can be chemically modified during their synthesis in order to tailor the desired mechanical, electronic and optical properties of the final product. LÄS MER
7. Organic Bioelectronics : Electrochemical Devices using Conjugated Polymers
Sammanfattning : Since the Nobel Prize awarded discovery that some polymers or “plastics” can be made electronically conducting, the scientific field of organic electronics has arisen. The use of conducting polymers in electronic devices is appealing, because the materials can be processed from a liquid phase, much like ordinary non-conducting plastics. LÄS MER
8. Alternative employment and well-being : Contract heterogeneity and differences among individuals
Sammanfattning : The increasing use of temporary and part-time employment in recent decades was initially expected to lead to negative effects for the individual. The empirical evidence, however, has been equivocal and the consequences are therefore still unclear. LÄS MER
9. Characterization and Compensation of Hardware Impairments in Transmitters for Wireless Communications
Sammanfattning : Increasing demands for data rate, energy efficiency and reliability in wireless communications have resulted in the introduction of radio frequency (RF) multiple input multiple output (MIMO) transmitters. However, MIMO transmitters suffer from additional crosstalk impairments along with the power amplifier (PA) and I/Q imbalance distortions observed in single input single output (SISO) transmitters.

10. Digital Baseband Modeling and Correction of Radio Frequency Power Amplifiers
Sammanfattning : Aspects related to behavioral modeling and correction of distortions for radio frequency (RF) power amplifiers (PAs) are treated in the thesis. When evaluating the performance of a behavioral model it is important to, first of all, use an evaluation criterion, and second, make sure that the criterion actually tells something about the behavior one wishes to describe.
