  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. FPGA Implementation of Feature Matching in ORB-SLAM2

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Hannah Lindström; [2022]
    Nyckelord :Autonomous navigation; SLAM; Feature matching; FPGA; ORB; Heterogeneous binary tree; Technology and Engineering;

    Sammanfattning : Simultaneous Localization And Mapping (SLAM) is an important component in solving the problem of autonomous navigation — allowing machines such as selfdriving cars and mobile robots to find their way in the world without human instruction. Though there is a steadily growing body of literature in the field of SLAM, far fewer works currently address using hardware acceleration to speed up this computationally heavy task. LÄS MER

  4. 3. 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

  5. 4. Classification of Perfect codes in Hamming Metric

    Master-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Tanveer Sabir; [2011]
    Nyckelord :Hamming metric; Hamming code; Hamming bounds; Cyclic codes; Perfect;

    Sammanfattning : The study of coding theory aims to detect and correct the errors during the transmission of the data. It enhances the quality of data transmission and provides better control over the noisy channels.The perfect codes are collected and analyzed in the premises of the Hamming metric. LÄS MER

  7. 5. Classification of perfect codes and minimal distances in the Lee metric

    Master-uppsats, Institutionen för datavetenskap, fysik och matematik, DFM

    Författare :Naveed Ahmed; Waqas Ahmed; [2010]
    Nyckelord :Hamming metric; Lee metric; Perfect codes; Minimal distance;

    Sammanfattning : Perfect codes and minimal distance of a code have great importance in the study of theoryof codes. The perfect codes are classified generally and in particular for the Lee metric.However, there are very few perfect codes in the Lee metric. The Lee metric hasnice properties because of its definition over the ring of integers residue modulo q. LÄS MER
