1. Vibroacoustic Analysis of an OLTC Diverter Switch for Condition Monitoring : Time frequency analysis with Fourier and wavelet transform in combination with multivariate logistic regression for condition monitoring of OLTC diverter switch
University essay from Uppsala universitet/Avdelningen för systemteknikAbstract : Vibrations are everywhere around us all the time and we often recognise them as sounds that we can hear and analyse with our brain. In this thesis, data that has been gathered from a diverter switch (DS) in a controlled environment, is analysed. READ MORE

2. Design and implementation of an energy harvesting system in a prosthetic limb
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : Energy Harvesting, also known as power harvesting or ambient power, is the process of obtaining small amounts of power from secondary sources, such as vibrations, light, temperature variations and even radio-frequency emissions. These systems have been uncommon in personal and wearable electronics in the past, however they are slowly gaining traction. READ MORE

3. Electrifying Agricultural Implements : A study of design implications of electrification
University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och designAbstract : As the world seeks to become less reliant on fossil fuels and use more electric energy instead new possibilities for development of agricultural implements opens. Major tractor manufacturers have recently announced tractors with over tenfold increases in electrical power. READ MORE

4. Analysis of high-voltage low-current DC/DC converters for electrohydrodynamic pumps
University essay from Uppsala universitet/Institutionen för elektroteknikAbstract : Moving parts cause vibrations and tend to wear out. In applications where maintenance is complicated, solutions without moving parts are therefore advantageous. Electrohydrodynamic pumps are such a solution. Instead of mechanical propulsion, they use strong electric fields to induce movement in a dielectric cooling liquid. READ MORE

5. Measurement of mechanical vibrations : Measurement of ambient energy in the form of mechanical vibrations in transportation, storage and installment for the use of self-powered wireless sensor networks
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : This project aims to explore the feasibility of using energy harvesting to create a self-powered sensor node that doesn't require batteries. The project was initiated by Ericsson, who identified a need to monitor their radio products during delivery to ensure they are not damaged by vibrations that exceed design specifications. READ MORE
