1. 6. Application of ring statistics to characterise graphitisation of carbon fiber heat shields under atmospheric re-entry conditions

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Hamish Keay; [2023]
   Keywords : Aerospace; Heat shields; Re-entry; Graphitisation; Carbon fiber; Carbon phenolic; Ring statistics; Graph theory; Molecular Dynamics; återinträde; grafitisering; kolfiber; kolfenol; ringstatistik; grafteori; molekylär dynamik;

   Abstract : Carbon fibers submitted to high temperatures (>2000 °C) experience a permanent increasein their thermal conductivity. This change has been attributed to a change in the molecularstructure due to graphitisation. READ MORE

3. 7. Cospectral graphs : What properties are determined by the spectrum of a graph?

   University essay from Uppsala universitet/Sannolikhetsteori och kombinatorik

   Author : Erik Sundström; [2023]
   Keywords : graph theory; graph; graphs; spectral graph theory; cospectral graphs; adjacency matrix; adjacency matrices; graph spectrum; spectrum; graph spectra; spectra;

   Abstract : This paper was written as a bachelor thesis in mathematics. We study adjacency matrices and their eigenvalues to investigate what properties of the corresponding graphs can be determined by those eigenvalues, the spectrum of the graph. The question of which graphs are uniquely determined by their spectra is also covered. READ MORE

4. 8. Co-Authorship Network Analysis in Constraint Programming Research

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Lana Ali; [2023]
   Keywords : Centrality; co-authorship; constraint programming research; graph theory; social network analysis ;

   Abstract : The aim of this thesis was to study co-authorship in the constraint programming research community. This was done by conducting social network analysis (SNA) based on published scientific papers from the proceedings of the International Conference on Principles and Practice of Constraint Programming.

5. 9. Manufacturing Knowledge Management Using a Virtual Factory-Based Ontology Implemented in a Graph Database

   University essay from Högskolan i Skövde/Institutionen för ingenjörsvetenskap

   Author : Mehran Ghorbani Tajani; [2022]
   Keywords : Knowledge Management; Ontology; Graph database; Graph theory; Virtual Factory; Knowledge-Driven Optimization;

   Abstract : Ontology-based technologies like Semantic Web and Knowledge Graphs are promising for knowledge management in manufacturing industries. In the literature there are abundant of publications related to using ontologies to represent and capture knowledge in manufacturing. READ MORE

6. 10. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Author : Felicia Törning; [2022]
   Keywords : Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

   Abstract : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose.
