  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. Single-peaked gamma-ray bursts in the Fermi GBM catalogue

    Master-uppsats, KTH/Fysik

    Författare :Henric Hintze; [2022]
    Nyckelord :astroparticle physics; GBR; gamma-ray burst; single-peaked; single peaked; shock breakout; Fermi; GBM; gamma-ray burst monitor; light curve; low-luminosity; low luminosity; closure relation; astropartikelfysik; GBR; gammablixt; singelpeakad; shockbreakout; Fermi; GBM; gammablixtmonitor; ljuskurva; ljuskurvor; lågluminositets;

    Sammanfattning : Gamma-ray burst light curves are notoriously irregular, yet a significant number consists of a single fast-rising, exponentially decaying pulse. These are called single-peaked light curves. LÄS MER

  4. 3. Study of the in-flight calibration of theSVOM/ECLAIRs instrument

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Jakob Östberg; [2020]
    Nyckelord :Telescope; calibration; gamma-ray; burst; ECLAIRs; SVOM; IRAP;

    Sammanfattning : The Space based multi-band Variable astronomical Object Monitor (SVOM) is a x- andgamma-ray telescope with the primary objective of observing gamma-ray bursts. Themission is a cooperation between the French and Chinese space agencies and will be launchedin 2021. LÄS MER

  5. 4. Modeling the complex ejecta on 2017 September 6-9 with WSA-ENLIL+Cone and EUHFORIA

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Anita Linnéa Elisabeth Werner; [2018]
    Nyckelord :CME; space weather; forecast; prediction; WSA-ENLIL Cone; EUHFORIA; preconditioning; type II radio burst; kmTII; dcld; September 2017; geoeffective;

    Sammanfattning : Three CMEs which erupted on 2017 Sep 4 and 6 underwent mutual interaction before reaching Earth on Sep 6-9, where it gave rise to a complex and unexpectedly geoeffective structure as detected by WIND at L1. The spacecraft first observed an interplanetary (IP) shock on Sep 6 followed by a turbulent sheath. LÄS MER

  7. 5. Fuzzy Flow Regulation for Network-on-Chip based Chip Multiprocessors Systems

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Yuan Yao; [2014]
    Nyckelord :;

    Sammanfattning : As large uniprocessors are no longer scaling in performance, chip multiprocessors (CMP) become the mainstream to build high-performance computers. CMP chips integrate various components such as processing cores, L1 caches and L2 caches (some also contain L3 caches, for example, in the IBM Power7 multicore processor) together, and multiple CMP chips with external memory banks make up a CMP system.
