  1. 1. Improving Dependability of Space-Cloud Payload Processor by Storage System

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Hassan Said; Stephanie Liza Johansson; [2023]
    Nyckelord :Fault tolerant; Markov analysis; Onboard processing; SSD array architecture; SSD; EDAC; RAID; Hamming code; Reed Solomon; Dependability evaluation; File systems; ZFS; Ext4.;

    Sammanfattning : Due to the usage of complicated platforms and current high-performance space computing technology, onboard processing in small satellites is expanding. Space-cloud payload processors with Commercial Off-The-Shelf (COTS) components, that are required to be radiation-tolerant, are used to perform the onboard processing. LÄS MER

  3. 2. 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

  4. 3. Tiered Storage Architecture for Stream Processing Systems

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

    Författare :Ao Song; [2022]
    Nyckelord :State Backend; Stream Processing; Embedded Backend; External Backend; Tiered Storage System; State Backend; Strömbehandling; Inbäddad Backend; Extern Backend; Lagringssystem i Nivåer;

    Sammanfattning : State management is the key component of a stateful stream processing system. Normally a stream processing system supports either an embedded state backend or an external backend. An embedded backend will store the data locally on the computing node. It is efficient to read and write but will lose the capability to scale out the system. LÄS MER

  5. 4. The local potential of V2G : Estimation of the benefits of Vehicle to Grid in the energy community of Stenberg

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

    Författare :Cyprien Drommi; [2022]
    Nyckelord :Vehicle to Grid; V2G; V2X; Electric vehicle; Energy community; Stenberg; Ancillary services; Frequency regulation; FCR; Energy arbitrage; Battery degradation; DC charging.; Vehicle to Grid; V2G; V2X; Elbilar; Elfordon; Energisamfälligheten; Stenberg; Stödtjänster; Frekvensbalancering; FCR; Energiarbitrage; Batteridegradering; Likströmsladdning.;

    Sammanfattning : In the countries willing to follow an energy transition towards decarbonization, a strong emphasis is put on electrification. Carbon-free power production tends to rely more on intermittent renewable energies, bringing many uncertainties on the electricity output to the grid. LÄS MER

  7. 5. Developing a tool for sizing and comparison of solar power storage systems.

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

    Författare :Malik Shehzad Hassen; [2022]
    Nyckelord :;

    Sammanfattning : This thesis presents the methodology to optimize the components of different storage technologies, i.e. hydrogen and batteries, integrated to photovoltaic system for hourly demand and annual-hourly irradiance values. The tool also allows comparing these two systems from techno-economic and environmental perspectives. LÄS MER
