  1. 1. Design and implementation of an energy harvesting system in a prosthetic limb

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ódinn K. Rúnarsson; [2023]
    Nyckelord :Energy harvesting; Prosthetic limbs; Supercapacitors; Printed circuit boards; 3D printing; Energiinsamling; Lemmproteser; Superkondensatorer; Tryckta kretskort; 3D Utskrivning; Orkuöflun; Gervilimir; Ofurþéttar; Prentaðar rafrásir; Þrívíddarprentun;

    Sammanfattning : 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. LÄS MER

  3. 2. Development of acomplex robot structure : Development and analysis of a cast triple traction system for the robotoperating at CERN facilities

    Magister-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Gerard Aliana Cervera; [2023]
    Nyckelord :CERNBot; Traction; Topology optimization; Sand casting;

    Sammanfattning : All devices working in hazardous environments have specific requirements to reduce the intervention of human power as much as possible. The robot that this thesis is focused on is no exception to this rule. LÄS MER

  4. 3. Säker bortkoppling av balpress vid brand : en studie om skademinimering vid brand i bogserat redskap

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Jens Kårhammer; Jesper Gustafsson; [2022]
    Nyckelord :maskinbrand; balpress; halmpressning; kuldrag; machine fire; baler;

    Sammanfattning : En stor risk vid pressning av halm är att en brand uppstår i balpressen. Balpressens flertal rörliga delar i kombination med torra, varma och dammiga förhållande är en bidragande orsak till bränderna och att dessa snabbt riskerar att bli omfattande. LÄS MER

  5. 4. Efficiency Comparison between Two-Level and T-Type Inverter for 800 V Automotive Application

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Rishabh Jain; [2022]
    Nyckelord :Electric Vehicles; Efficiency Comparison; Loss Calculation; SiC MOSFET; T-Type Inverter; Three-level Inverter; Two-level Inverter; Inverter i två nivåer; inverter av T-typ; inverter i tre nivåer; SiC MOSFET; förlustberäkning; verkningsgradsjämförelse; elfordon;

    Sammanfattning : The falling cost of batteries, along with an increasing need to cut emissions, has spurred significant interest in the electrification of vehicles. In addition, as semiconductor devices have evolved, the research for electric vehicles with higher battery voltage has increased. LÄS MER

  7. 5. Evaluation of Discrete-Time Wideband Receivers for NB-IoT

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Magnus Wasting; [2021]
    Nyckelord :Discrete; time; filter; NB-IoT; Charge; Sharing; CMOS; Technology and Engineering;

    Sammanfattning : A receiver that covers several RF bands requires multiple front-end filters which increases the cost in terms of components and/or board/silicon area. Front-end filters assist a receiver to withstand interference at multiples of its down-conversion frequency. LÄS MER
