- An exploratory study on the prosodic signaling of ‘confirmation’ in Swedish is presented. Pairs of subjects read short dialogs, constructed around selected target words, in a conversational style. A falling utterance intonation was found on the target word, and the signaling of word prosody (lexical pitch accent) appeared to be, to a certain degree, optional.

- This paper describes the design, simulation and measurement of a GaN power amplifier suitable for envelope and phase signal combination. The low-frequency envelope signal is used to vary the gate (bias) voltage of the device, resulting in a pulse width modulated drain voltage, while modulation of supply voltage or current is avoided. The test circuit is implemented using a discrete GaN HEMT power amplifier and discrete surface-mount passive components assembled on a PCB. Measurements showed a maximum drain efficiency of 59% at 360 MHz, at an output power of 29 dBm. The output power as a function of the gate bias voltage varied between 3 and 29 dBm, with the drain efficiency varying between 6 and 59%.

Discourse Analysis — A Critical or Relativistic Perspective in Music Education?
- 2007

Konferensbidrag (refereegranskat)abstract
- The purpose of this paper is to discuss the problems I have encountered under the development of the theoretical perspective of my thesis. First, discourse analysis is founded in social constructionism and post-structuralistic theory. Second, discourse analysis is a concept including different perspectives, where both more critical approaches with focus on discourses as determining and more relativistic approaches with focus on the actor and language appear. With the critical approach there is an epistemological possibility, a claim of knowledge. That would be unacceptable in relativistic discourse analysis where pluralism is a keyword and every stake is equal. Does a relativistic study add anything of value or is a critical approach most fruitful? I find it interesting to discuss consequences for a study from both a critical and a relativistic perspective. Furthermore, it is challenging to try to merge the two approaches.
