  1. 1. Sustainability of Artificial Turf Fields : Comparative life cycle assessment of artificial and natural turf fields

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Mikael Säberg; [2021]
    Keywords : artificial turf; natural turf; life cycle assessment; infill materials; water consumption;

    Abstract : Soccer accounts for a third of the Swedish sports movement with 3 503 fields of both natural and artificial turf. The European Union will make a decision in 2021 on how to handle the issue of rubber performance infill. This infill can be found in artificial turf fields and are used for performance properties.

  3. 2. Investigation of Hybrid Simulation Methods for Evaluation of EMF Exposure in Close Proximity of 5G Millimeter-Wave Base Stations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Anguiano Sanjurjo; [2020]
    Keywords : 5G; base station; EMF exposure; hybrid simulation method; millimeter wave;

    Abstract : With the emergence of Fifth Generation (5G) mobile networks, the employment ofhigher frequencies in the millimeter-wave (mmWave) range and the realization of agreat number of beams in 5G radio base stations (RBS) make the electromagnetic (EM)simulation of RBS products very costly in terms of hardware and time requirements.In order to compute the electromagnetic field (EMF) exposure in close proximity of theRBS, more efficient simulation methods are required.

  4. 3. Investigation of Near-Field Contribution in SBR for Installed Antenna Performance

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Harald Hultin; [2019]
    Keywords : Shooting and Bouncing Rays; Geometrical Optics GO ; Physical Optics PO ; antenna modeling; computational electromagnetics CEM ; CST; dipole; ray tubes; Geometrisk Optik; Fysikalisk Optik; antennmodellering; elektromagnetism; CST; dipol;

    Abstract : To investigate near-eld contributions for installed antennas, an in-house code iswritten to incorporate near-eld terms in Shooting and Bouncing Rays (SBR). SBRis a method where rays are launched toward an object and scatter using GeometricalOptics (GO). These rays induce currents on the object, from which the totalscattered eld can be found. READ MORE

  5. 4. Hydrogen production from automotive waste via integrated plasma gasification and water gas shift.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Marco Occhinero; [2019]
    Keywords : ;

    Abstract : The growing amount of landfilled waste could pose a problem in many parts of the world due to the scarcity of landfilling space and environmental threats. In particular, automotive shredder residue (ASR) waste, a by-product of the dismantling of End of Life Vehicles (ELVs), has been proven to represent an issue in particular in the EU, where countries are struggling to compel to the directives that regulate this type of waste.

  6. 5. Silicon-based graphite electrodes for Li-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Rassmus Andersson; [2018]
    Keywords : silicon graphite electrodes; li-ion battery; silicon graphite anode; silicon electrode; silicon anode;

    Abstract : The cycling performance of silicon containing graphite electrodes as the anode in lithium-ion batteries has been investigated. Different electrode compositions of silicon, graphite, carbon black, sodium carboxymethylcellulose (CMC-Na), styrene–butadiene rubber (SBR) and using water as the solvent have been prepared and evaluated electrochemically by constant-current-constant-voltage (CCCV) cycling.
