  1. 1. Route Planning of Battery Electric Heavy-Duty Commercial Vehicles : Using Contraction Hierarchies and Mixed Integer Programming

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Datalogi

    Författare :Olle Delborg; Elias Insulander; [2023]
    Nyckelord :route planning; route optimization; contraction hierarchies; mixed integer programming; vehicle routing problem; electric trucks; electric vehicles; battery; openstreetmap; shortest path; Dijkstra;

    Sammanfattning : This thesis addresses route planning of Battery Electric Heavy-Duty Commercial Vehicles to enhance the reliability of electric vehicle transport. Collaborating with Scania, a Swedish truck manufacturing company, the goal is to develop a pipeline that uses open source data from OpenStreetMap and performs a modified Contraction Hierarchy in order to create a graph that can be used as input to a modified Vehicle Routing Problem formulation using Mixed Integer Programming.

  3. 2. Evaluating Security Mechanisms of Substation Automation Systems

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

    Författare :Ziyang Zhou; [2023]
    Nyckelord :Substation automation system; Threat modeling; Meta attack language; Stationsautomationssystem; Hotmodellering; Meta attack language;

    Sammanfattning : Substations are important components for transforming voltage and distributing power in electrical infrastructure. Modern substations are usually automated by substation automation systems, which offload the work of operators and reduce potential human error. LÄS MER

  4. 3. Knowledge Graph Creation and Software Testing

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Författare :Aishwarya Kyasa; [2023]
    Nyckelord :RDF; IKEA Approach; RML; Data Transformation; Knowledge Graph Creation.;

    Sammanfattning : Background: With the burgeoning volumes of data, efficient data transformation techniques are crucial. RDF mapping language has been recognized as a conventional method, whileIKEA the Knowledge graph’s approach brings a new perspective with tailored functions and schema definitions. LÄS MER

  5. 4. Decoding communication of non-human species - Unsupervised machine learning to infer syntactical and temporal patterns in fruit-bats vocalizations.

    Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Luigi Assom; [2023]
    Nyckelord :animal decision making; unsupervised machine learning; UMAP; autoencoders; classifiers; bioacoustics; combinatory syntax; animal communication;

    Sammanfattning : Decoding non-human species communication offers a unique chance to explore alternative intelligence forms using machine learning. This master thesis focuses on discreteness and grammar, two of five linguistic areas machine learning can support, and tackles inferring syntax and temporal structures from bioacoustics data annotated with animal behavior.

  7. 5. Domain-specific knowledge graph construction from Swedish and English news articles

    Master-uppsats, Uppsala universitet/Institutionen för lingvistik och filologi

    Författare :Aleksandra Krupinska; [2023]
    Nyckelord :knowledge graph; information extraction; knowledge representation; Swedish; English;

    Sammanfattning : In the current age of new textual information emerging constantly, there is a challenge related to processing and structuring it in some ways. Moreover, the information is often expressed in many different languages, but the discourse tends to be dominated by English, which may lead to overseeing important, specific knowledge in less well-resourced languages.
