  1. 16. Modelling of a Planar Magnetic Component for PCB-Integration

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Yoann Pascal; [2016]
    Nyckelord :;

    Sammanfattning : The trend toward the electrification of functionalities magnifies the part played by power electronic converters, which are continuously expected to deliver more power, at a lower cost, in a smaller volume and always with a high reliability. To this end, high switching frequency integrated converters, and especially Printed-Circuit-Board (PCB) –integrated devices, could embody an interesting paradigm. LÄS MER

  3. 17. Carbon Nanotubes : A Theoretical study of Young's modulus

    Uppsats för yrkesexamina på avancerad nivå, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Tore Fredriksson; [2014]
    Nyckelord :Carbon nanotube; Density Functional Theory. DFT; Augmented Plane Wave Method; APW; ELK;

    Sammanfattning : Carbon nanotubes have extraordinary mechanical, electrical, thermal andoptical properties. They are harder than diamond yet exible, have betterelectrical conductor than copper, but can also be a semiconductor or evenan insulator. These ranges of properties of course make carbon nanotubeshighly interesting for many applications. LÄS MER

  4. 18. Modelling a Mineral Froth Flotation Process : Case Study: Minerals process at Boliden AB

    Master-uppsats, Institutionen för tillämpad fysik och elektronik

    Författare :Bilal Ur Rehman; [2011]
    Nyckelord :copper flotation process; system identification;

    Sammanfattning : We present an approach to model the dynamic of a copper flotation process. The conventional approach of system identification is applied to model the dynamics. In this research, experiments are performed to collect process data of determined input and output variables. LÄS MER

  5. 19. Riskbedömning vid Saltvikens kopparverk

    Magister-uppsats, Naturvetenskapliga institutionen

    Författare :Daniel Hellqvist; [2009]
    Nyckelord :riskbedömning; koppar; zink; bly; kopparverk; saltviken;

    Sammanfattning : Abstract At Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. LÄS MER

  7. 20. Modelling Copper Sources and Fate in Lake Råcksta Träsk, Stockholm : Sediment Copper Content as Indicator of Urban Metal Emissions

    Master-uppsats, KTH/Industriell ekologi

    Författare :Rajib Sinha; [2009]
    Nyckelord :copper; source; fate; urban; modelling; lake;

    Sammanfattning : In Stockholm, Sweden, diffuse emissions of metals have become the dominating source of copper towater. This thesis work made an attempt to link the source of copper emission and the fate of the copper in a lake. These models have been applied in the case study of Lake Råcksta Träsk and its urban drainage area in Stockholm, Sweden. LÄS MER
