  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

    Nyckelord :error-correcting codes; Reed-Muller; coding; decoding; communication; coding theory; felrättande koder; Reed-Muller; kodningsteori; kod; kodning; kommunikation;

    Sammanfattning : In this thesis some families of linear error correcting codes are presented. The reader will find a general description of binary codes and more specific details about linear codes such as Hamming, repetition codes, Reed-Muller codes, etc. LÄS MER

  5. 4. Software based memory correction for a miniature satellite in low-Earth orbit

    Kandidat-uppsats, KTH/Skolan för datavetenskap och kommunikation (CSC)

    Författare :John Wikman; Johan Sjöblom; [2017]
    Nyckelord :Software based memory correction; DRAM; Reed-Solomon; Hamming; CubeSat; Low-Earth Orbit; MIST;

    Sammanfattning : The harsh radiation environment of space is known to cause bit flips in computer memory. The conventional way to combat this is through error detection and correction (EDAC) circuitry, but for low-budget space missions software EDAC can be used. LÄS MER

  7. 5. Nonexistence Theorems for Perfect Codes over Finite Fields

    Kandidat-uppsats, Lunds universitet/Matematik (naturvetenskapliga fakulteten)

    Författare :André Jönsson; [2012]
    Nyckelord :perfect codes mathematics; Mathematics and Statistics;

    Sammanfattning : In this survey, we consider the trivial perfect codes which are the binary repetition codes of odd length and all codes that only contain one code word. We also take into acount, the Hamming codes as well as the two perfect Golay codes. LÄS MER
