1. The contemporary string instruments : How to master extended bowed string instrument performance techniques
Master-uppsats, Kungl. Musikhögskolan/Institutionen för klassisk musikSammanfattning : In this study, the focus is on techniques for playing contemporary music on the viola and other bowed string instruments. These techniques include playing overpressure, some percussion techniques, special pizzicato and left-hand pizzicato techniques, different contact point techniques, various harmonic techniques such as Effleuré, multiphones and subharmonics, and trills.

2. Konstruktion av mätinstrument för vibrationsmätning
Master-uppsats,Sammanfattning : A mass imbalance in the driveline of a hydro power plant is a common source to vibrations. These vibrations have the frequency of rotation accompanied by harmonics and subharmonics. Vibrations cause ware and tare on components and in the long term defect bearings. LÄS MER
3. Linear Time Periodic Analysis of Dc-Dc converter
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknikSammanfattning : Aim of this thesis is to analyze Dc-Dc converters by using the techniques of Linear Periodic Time varying (LTP) systems to estimate the amount of subharmonics injected in the load. Dc-Dc converters are used to transform a Dc input to a Dc output of different voltage. In this thesis we study in particular the so called "switch mode" converters. LÄS MER
