1. 1. End User Study of an Engineering Design Tool

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

   Författare :Ina Johnson; Ann-Sofie Eriksson; [2023-09-21]
   Nyckelord :user frustrations; case study; re-engineering;

   Sammanfattning : [Context and Motivation] PROSIT+ Designer is a Volvo Group-developed application focused on operational development for vehicle production. Since its launch, 15 years ago, PROSIT+ Designer has not had any major revisions or updates. [Question/problem] The frustrations from end users are, as a result, piling up. LÄS MER

3. 2. Audio Anomaly Detection in Cars

   Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

   Författare :Asma Hussein; [2023-09-11]
   Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

   Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

4. 3. 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.

5. 4. 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.

7. 5. Systematically Analyzing Synthetic Automotive Data to support Space Filling Curves-based Maneuver Detection

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

   Författare :Alexandre Rancati-Palmer; Christopher Axt; [2023-08-03]
   Nyckelord :Morton; Carla; autonomous driving; edge case;

   Sammanfattning : Context: In autonomous driving system development, the identification of maneuvers within large datasets is progressively becoming more complex, primarily due to the inherent complexity arising from the multidimensional nature of the data describing these maneuvers. In this context, algorithms based on Space-Filling Curves can be an effective way to index datasets by creating a single-dimensional representation of the maneuvers. LÄS MER
