  1. 11. Powertrain of heavy electric vehicles: : Analysis of the production chain and impact on environment and industry

    University essay from KTH/Energiteknik

    Author : Svenja Gelpke; [2018]
    Keywords : ;

    Abstract : Elektrifiering av bilar och mindre transportfordon pågår och flottaaktier ökar men diskussionen om elektrifiering av långdistanstransport är relativt ny. Elektriska lastbilar som använder fossila bränslen och som produceras med förnybara energikällor är lovande, särskilt i länder med en ren elmix. READ MORE

  3. 12. Modeling Region Granularity of the D2M Memory SystemPin Tool driven test for the Split CacheHierarchy

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Johan Snider; [2018]
    Keywords : ;

    Abstract : Cache simulation is a potentially complex and time consuming task in the field of computer architecture. Often, only parts of a program are simulated due to practical time constraints. This thesis proposes a way to simulate entire benchmark programs using the Intel Pin platform (PIN) for research into the Directto-Master memory system (D2M). READ MORE

  4. 13. Analytical calculation model used when dimensioning timber poles used as overhead power line supports

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Christopher Ekängen; [2018]
    Keywords : Calculation model; timber poles; overhead power line;

    Abstract : Overhead power lines are more reliable and cost effective than underground cables when it comes to power transmission. The overhead power lines are often suspended above ground using timber pole supports. READ MORE

  5. 14. Test Grids for Reliability analysis : Analysing interruptions and developing test grids based on Mälarenergi Elnät distribution grid

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Jonas Eld; Jens Melin; [2017]
    Keywords : ;

    Abstract : The purpose of this degree project is to examine power outages that has occurred during the years 2009 and 2016 on Mälarenergi Elnät distribution grid. Interruptions that has occurred on 10 kV voltage level and on overhead lines or underground cable was examined. The examined interruptions are based on the DARWin data from Mälarenergi Elnät.

  6. 15. Grounding of distrubution grids : High impedancegrounding compared to solid grounding with Fault Current Limiter

    University essay from

    Author : Maria Kättström; [2017]
    Keywords : ;

    Abstract : Today cables replace overhead lines in distribution systems and cause higher system capacitance and higher capacative fault currents. This fault current, in the fault location, is limited by a Petersén coil and a resistance in parallel when a fault occurs in so called “high impedance grounded systems” which are commonly used in Europe.
