  1. 6. High-Speed Communication Scheme in OSI Layer 2 Research and Implementation

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Ahmadmunthar Zaklouta; [2019]
    Nyckelord :FPGA; CDR; High-Speed Serial Communication; BER; CDC; UART;

    Sammanfattning : This thesis is part of a project at Bombardier’s Object Controller System. This system acts as a communication interface for several sub-systems that control the railway traffic. LÄS MER

  3. 7. Performance of Network and Transport Protocols in the Implementation of a New Cryptocurrency

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jesper Hagström; Lukas Lindblom; [2018]
    Nyckelord :Cryptocurrency; Good money; Transport; Network; Protocol; Performance; Comparison; Simulation; KTH; OSI; TCP; UDP; IPv6; IPv4; HAJ Enterprise.;

    Sammanfattning : It has been suggested that some cryptocurrencies have potential to take the role as a global digital payment system. However, as the current technology stands, all cryptocurrencies have shortcomings which are growing when scaling parameters. LÄS MER

  4. 8. PHYSICAL LAYER SECURITY USING PSEUDO-RANDOM SEQUENCE KEY GENERATION

    Master-uppsats,

    Författare :Srihari Arolla; Naga Venkata Sai Teja Gurrala; [2018]
    Nyckelord :Physical Layer Security; Bit Error Rate; Key Error Rate; Pseudo Random Generator; Secret Key.;

    Sammanfattning : Nowadays, network security plays a major role in the field of wireless communications. Wired networks propagate electrical signals or pulses through cables. Whereas wireless signals propagate through the air. If wireless networks are left open and exposed to the outside world, there are high chances of being misused by others. LÄS MER

  5. 9. Investigating the Neural Correlates of Perceived Social Isolation : Is Perceived Social Isolation Confined to the Social Brain?

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Kasper Löf; [2018]
    Nyckelord :Perceived Social Isolation; hypervigilance; social brain model; loneliness;

    Sammanfattning : Loneliness, or the perceived discrepancy of ones relationships in terms of quality, is known as Perceived Social Isolation (PSI). Studies have shown that PSI is both increasing and is correlated with health risks. Specifically, PSI is not only related with risks of mortality but is also linked with variations in the brain.

  7. 10. Network Traffic Regulator for Diagnostic Messages in Modular Product

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

    Författare :Nikhil Thakrar; [2017]
    Nyckelord :Controller Area Network; CAN; Diagnostics; Scania; UDS; KWP; OBD; J1939; Network regulator; bandwidth management; Token Bucket; Traffic shaping; vehicle; bit stuffing; OSI model; arbitration;

    Sammanfattning : The aim of this thesis project is to explore a network traffic regulator using bandwidth management techniques that regulates data traffic with the objective to use the network bandwidth to its maximum capacity while ensuring that the network is not overloaded. The bandwidth in the existing network architecture is shared between two co-existing, distinct data flows for on-board communication and diagnostic communication in an in-vehicle network. LÄS MER
