  1. 1. Evaluation of pharmaceutical removal in seven WWTPs : Efficiency of different treatment technologies

    Master-uppsats, Stockholms universitet/Institutionen för miljövetenskap

    Författare :Viktor Munkhammar; [2023]
    Nyckelord :Pharmaceuticals; wastewater treatment plant; removal efficiency; biological treatment; ozonation;

    Sammanfattning : Wastewater treatment plants (WWTPs) are originally not constructed to remove pharmaceuticals from the wastewater. Biological treatment technologies used in many WWTPs today, e.g., activated sludge, MBBR and trickling filters, can, however, remove some pharmaceuticals well. LÄS MER

  3. 2. Development of a Hydraulic Front Wheel Drive for a Battery Electric Truck

    Master-uppsats, Linköpings universitet/Fluida och mekatroniska system

    Författare :Johan Humla; Samuel Friman; [2023]
    Nyckelord :;

    Sammanfattning : This master thesis work has been executed at Volvo GTT in Gothenburg. Focus has beenlaid on implementing a hydraulic front wheel drive (HFWD) system on a battery electricvehicle (BEV). The earlier concept builds have been performed on internal combustionengine (ICE) driven trucks at Volvo Trucks. LÄS MER

  4. 3. Alternative traction system for road-rail vehicles

    Master-uppsats, Lunds universitet/Innovation

    Författare :Jakob Runevad; [2023]
    Nyckelord :Product development; electric traction; construction equipment; road-rail vehicles.; Technology and Engineering;

    Sammanfattning : Excavators have traditionally been diesel driven with hydraulic actuators, but with the ongoing electrification of vehicles, smaller electric excavators are getting more common. Larger electrical excavators are still in a prototyping or early production stage but can be expected to grow. LÄS MER

  5. 4. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :María Xuan Celaya Granados; [2023]
    Nyckelord :;

    Sammanfattning : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. LÄS MER

  7. 5. Effektivisering av produktframtagningen för kundanpassade hydraulcylindrar genom användning av automationsramverk

    Master-uppsats, Linköpings universitet/Produktrealisering

    Författare :Axel Lundvik; [2023]
    Nyckelord :Designautomation; HLCt; KBE; Knowledge Based Engineering; Automationsramverk; Konfigurator; CAD; Visual Studio; VIsual Basic; XCC; Hydraulcylinder; Automation;

    Sammanfattning : Examensarbetet som detaljeras i denna rapport är utfört på uppdrag av företaget Xperdi AB, designautomationsexperter vars önskemål med projektet var en demonstration av effekten avdesignautomation. Projektförslaget innefattar utveckling och användningen av ett automationsramverk för automatisk generering av unika hydraulcylindermodeller efter specifika designkrav. LÄS MER
