  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. Unequal Error Protection for Wireless Imaging

    Master-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

    Författare :Sandya Rondla; [2009]
    Nyckelord :UEP; JPEG; ROI; BCH codes; Hamming codes; Gaussian channel; and Rayleigh fading.;

    Sammanfattning : This thesis work was to examine the unequal error protection (UEP) scheme for joint photographic experts group (JPEG) 2000 images over an additive white Gaussian noise (AWGN) and a Rayleigh fading channel. The JPEG 2000 standard provides an effective image compression that result in increasing effect of transmission errors. LÄS MER

  5. 4. Linear Unequal Error Protection for Region of Interest Coded Images over Wireless Channels

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för telekommunikationssystem

    Författare :Md. Khorshed Alam; [2005]
    Nyckelord :LUEP; ROI; JPEG2000; Rayleigh Fading; Wireless Channel;

    Sammanfattning : In this thesis, an unequal error protection scheme for transmitting JPEG2000 images over wireless channel is investigated. The rapid growth of wireless communication has resulted in a demand for robust transmission of compressed images over wireless networks. LÄS MER

  7. 5. Ternära koder för variabelt felskydd

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Björn Karlsson; [2002]
    Nyckelord :Datorteknik; ternära koder; variabelt felskydd; likaviktskoder; konstant sammansättningskoder; Datorteknik;

    Sammanfattning : Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. LÄS MER
