1. High quality frequency modulated halftoning
Abstract : The fact that most printing devices, such as laser printers, are restricted to very few colors has led to an increased interest in finding efficient techniques that transform a continuoustone image into a binary one. Such techniques are referred to as halftoning methods. READ MORE

3. On low-complexity frequency selective digital filters and filter banks
Abstract : En filterbank består av flera filter som arbetar tillsammans för att dela upp en signal i olika frekvensband. De kan också användas för att slå ihop signaler separerade i frekvensplanet till en enda. Sedan tidigt 70-tal har man lärt sig att designa förlustfria filterbankar som alltså inte introducerar några som helst fel i systemet. READ MORE

4. Multicriteria optimization for managing tradeoffs in radiation therapy treatment planning
Abstract : Treatment planning for radiation therapy inherently involves tradeoffs, such as between tumor control and normal tissue sparing, between time-efficiency and dose quality, and between nominal plan quality and robustness. The purpose of this thesis is to develop methods that can facilitate decision making related to such tradeoffs. READ MORE

5. Control and Analysis of Pulse-Modulated Systems
Abstract : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. READ MORE
