  1. 1. Mining infrequent group of motifs from multidimensional time series: A case study at Alfa Laval AB

    University essay from Högskolan i Halmstad/Akademin för informationsteknologi

    Author : Fabeena Thoufeeq; Reeba Susan Ashok; [2024]
    Keywords : ;

    Abstract : In collaboration with an industrial partner, Alfa Laval AB, this thesis discusses a novel approach for identifying operational modes, specifically a cleaning mode, in separator machines without the benefit of labelled data and with very limited operating knowledge. Understanding the operational modes is crucial for comprehending the machine’s behaviour and ensuring its optimal performance. READ MORE

  2. 2. Mobile Device Industry in China : A study on Chinese mobile device industry from an ecosystem point of view

This growth is driven by the advancement of 5G technology, which has revolutionized various aspects of the industry, including manufacturing, products, and consumer demand. READ MORE

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

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Abstract : 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. Systematically Analyzing Synthetic Automotive Data to support Space Filling Curves-based Maneuver Detection

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

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

    Abstract : 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. READ MORE

  5. 5. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nikolaos Kouskoulis; [2023]
    Keywords : Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Abstract : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. READ MORE
