  1. 1. On Expressing Automotive Maneuvers with SFC

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Zizhuang Cui; Jiacheng Li; [2023-10-05]
    Nyckelord :space-filling curve; Software engineering; software testing; taxonomy;

    Sammanfattning : Conventional methods for testing autonomous driving software often involve dealing with a large number of dimensions, which can complicate the processing and analysis of test datasets. Therefore, there is a pressing need to develop a more efficient approach that is both time and cost-effective. LÄS MER

  2. 2. On Systematically Exploring the State Space for Events with SFCs

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Younis Akel; Gianmarco Iachella; [2023-08-07]
    Nyckelord :Autonomous driving systems; scenario-based testing; space-filling curve SFC ; characteristic stripe patterns CSP ; permutations; state-space; areas of interest AOI ;

    Sammanfattning : In the process of developing autonomous driving systems (AD systems), ensuring safety remains a constant and continuous priority. Scenario-based testing is a popular approach to guarantee the safety of AD systems, which however meets challenges in terms of diversity and efficiency of generation, as well as evaluating existing test case datasets in terms of their coverage of the different variations of a particular maneuver.

  3. 3. Comparing the Locality Preservation of Z-order Curves and Hilbert Curves

    Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Alex Nordin; Adam Telles; [2023-08-03]
    Nyckelord :space-filling curve; software engineering; software testing;

    Sammanfattning : Developing and testing software in the automotive industry and in the research of autonomous vehicles requires the costly querying of multidimensional data recorded from such a vehicle’s various sensors. Through encoding such data using space filling curves, faster queries could be achieved by reducing multiple dimensions into a singular dimension, while exploiting the patterns that emerge in the one-dimensional representation to still get accurate search results.

  4. 4. Detection Of Malicious Activity in Network Traffic on a Binary Representation using Image Analysis

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Joar Hjerpe; Oliver Karlsson; [2022]
    Nyckelord :Binary representation; Image Analysis; Spatial-Filling Curves; IIoT; Artificial intelligence;

    Sammanfattning : In this thesis, we explore the idea of using binary visualization and image analysis to detect anomalous activity on an Industrial Internet of Things (IIoT) based network. The data is gathered into a pcap file and then fed into our encoder, which uses a space-filling curve to convert the 1-dimensional stream of data into pixels with a specific red, blue, and green gradient value.

  5. 5. Parameter identification of GISSMO damage model for DOCOL 1200M : A study on crash simulation for high strength steel sheet components

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik

    Författare :Daniel Hörling; [2015]
    Nyckelord :;

    Sammanfattning : In the automotive industry there is a conflict between the need for weight reduction in order to reduce the CO2 emissions and the need for high safety. It has led to the use of high strength steel instead of the traditional lightweight materials. LÄS MER
