  1. 1. Modelling and Investigation of Control of a Power Infrastructure Resource Management System for a Radio Base Station : A study on sustainable power management for ICT infrastructure.

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

    Författare :Gustav Lenart; [2023]
    Nyckelord :Hybrid Dynamical Systems; Resource Management; Hybrid Automaton; Sustainable solutions for Wireless technology; Hybrid Dynamiska System; Resurshantering; Hybrid Automaton; Hållbara lösningar för trådlös teknologi;

    Sammanfattning : In order to minimize greenhouse gas emissions and operational cost related to the ICT-infrastructure the power management method of a Radio Base Station (RBS) or Base Transceiver Station (BTS) at Ericsson is studied and modelled. The major load demand at RBS’s are due to uplink and downlink data traffic. LÄS MER

  3. 2. Design of radio frequency energy harvesting system : for use in implantable sensors

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System; Linköpings universitet/Tekniska fakulteten

    Författare :Amir Ebrahimi; David Kihlberg; [2022]
    Nyckelord :RF energy harvesting; RF rectifier; efficiency; voltage sensor; voltage doubler;

    Sammanfattning : Implantable biomedical wireless sensors provide monitoring of vital health signs such as oxygen, temperature and intraocular pressure and may help to analyse and detect diseases in humans and animals. However, one of the design challenges of implantable devices is providing a safe and reliable energy source. LÄS MER

  4. 3. Removal of pharmaceutical residues from wastewater by oxidation with ozone

    Master-uppsats, KTH/Resursåtervinning

    Författare :Frida Söderström; [2021]
    Nyckelord :ozonation; adsorption; pollutants; pharmaceuticals; wastewater; ozonering; adsorption; föroreningar; läkemedel; vattenrening;

    Sammanfattning : Avloppsreningsanläggningar är idag utformade för att rena bort föroreningar i form av organiskt material, suspenderade fasta ämnen och växtnäringsämnen (exempelvis fosfater och nitrater). Myndighet i Sverige har satt upp restriktioner och lagar gällande hur mycket av de olika föroreningarna som det är okej att utgående vatten innehåller. LÄS MER

  5. 4. Solar Tent : A Photovoltaic Generator Model for a Flexible Fabric with Inbuilt Cells

    Författare :Ali Manhal; Tammam M. Ali; [2019]
    Nyckelord :Solar tent; PV system; refugee camp; PV monitoring system; and flexible PV modules;

    Sammanfattning : Natural disasters and conflicts in many different parts of the world force thousands of people to get displaced from their homes and live in refugee camps temporarily or permanently. For refugee families, lack of energy access has great impact on their lives. LÄS MER

  7. 5. A Prefeasibility Analysis of a PV Mini Grid with Ice Plant on Buvu Island in Lake Victoria

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Jonathan Daglish; [2019]
    Nyckelord :;

    Sammanfattning : Improving energy access through the provision of sustainable electrification is fundamental to reducing poverty and facilitating development in many areas of rural Sub Saharan Africa. The region currently suffers from severe energy inequality, with 81% of people relying on traditional forms of biomass for direct energy provision. LÄS MER
