  1. 11. Onboard computer fault-tolerance detection and mitigation

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

    Författare :Gustav Olofsson; [2020]
    Nyckelord :Onboard Computer; Exceptions; Error Handling; RTOS;

    Sammanfattning : The aim for this thesis is to design a software library responsible for preventing, detecting, handling and logging faults caused by radiation in a representable flight computer system based on the Cobham Gaisler GR740 quad-core LEON4FT processor chip. The LEON processor family is commonly used in space applications and it is based on the open SPARC instruction set and has been extended with fault tolerant features to cope with both on-chip radiation effects as well as upsets in external memory.

  3. 12. Performance optimization ofthe online data processing softwareof a high-energy physics experiment : Performance optimization ofthe online data processing softwareof a high-energy physics experiment

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Péter Kardos; [2020]
    Nyckelord :;

    Sammanfattning : The LHCb experiment probes the differences between matter and anti-matter by examining particle collisions. Like any modern high energy physics experiment, LHCbrelies on a complex hardware and software infrastructure to collect and analyze the data generated from particle collisions. LÄS MER

  4. 13. Real-time Outlier Detection using Unbounded Data Streaming and Machine Learning

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Datavetenskap

    Författare :Emelie Åkerström; [2020]
    Nyckelord :Outlier Detection; Unbounded Data Streaming; Machine Learning; Clustering; MiniBatchKMeans; LSTM AutoEncoder; Streaming; Network Monitoring;

    Sammanfattning : Accelerated advancements in technology, the Internet of Things, and cloud computing have spurred an emergence of unstructured data that is contributing to rapid growth in data volumes. No human can manage to keep up with monitoring and analyzing these unbounded data streams and thus predictive and analytic tools are needed. LÄS MER

  5. 14. Dynamic Eviction Set Algorithms and Their Applicability to Cache Characterisation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Maria Lindqvist; [2020]
    Nyckelord :microarchitectural attacks; cache attacks; side channel attacks; eviction set; cache memory;

    Sammanfattning : Eviction sets are groups of memory addresses that map to the same cache set. They can be used to perform efficient information-leaking attacks against the cache memory, so-called cache side channel attacks. In this project, two different algorithms that find such sets are implemented and compared. LÄS MER

  7. 15. Hantering av nätverkscache i DNS

    Kandidat-uppsats, Mittuniversitetet/Institutionen för informationssystem och –teknologi

    Författare :Hans Lindqvist; [2019]
    Nyckelord :Caching name server; DNS; Internet of Things; Ipv6; Unbound; PowerDNS Recursor; Cachande namnserver; DNS; Sakernas Internet; Ipv6; Unbound; PowerDNS Recursor;

    Sammanfattning : The Domain Name System, DNS, is a fundamental part in the usability of the Internet, but its caching function is challenged by the increase of address size, number of addresses and automation. Meanwhile, there are limits in the memory capacity of certain devices at the Internet’s edge towards the Internet of Things. LÄS MER
