1. 1. The contemporary string instruments : How to master extended bowed string instrument performance techniques

   Master-uppsats, Kungl. Musikhögskolan/Institutionen för klassisk musik

   Författare :Arttu Nummela; [2023]
   Nyckelord :contemporary music; contemporary bowed instrument techniques; extended technique practice;

   Sammanfattning : 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.

3. 2. Konstruktion av mätinstrument för vibrationsmätning

   Master-uppsats,

   Författare :Johan Olsson; [2016]
   Nyckelord :;

   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

4. 3. Linear Time Periodic Analysis of Dc-Dc converter

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

   Författare :Simone Del Favero; [2006]
   Nyckelord :HTM; Harmonic Transfer Matrix; HTF; Harmonic Transfer Function; LTP; Linear Time Periodic Systems; PWM; Dc-Dc converter; Pulse Width Modulator; subharmonics; chaos; subharmonic estimation; Technology and Engineering;

   Sammanfattning : 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
