1. 1. 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

3. 2. Exploring Ways of Visualizing Functional Connectivity

   University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Author : Jan Nylén; [2017]
   Keywords : Visualization; Data Visualization; Functional Connectivity; brain imaging; user centered design; interaction technology; design;

   Abstract : Functional connectivity is a field within neuroscience where measurements of co-activation between brain regions are used to test various hypotheses or explore how the brain activates depending on a given situation or task. After analysis, the underlying data in the field consists of a n by n adjacency matrix where each cell represents a correlation value between two regions in the brain. READ MORE

4. 3. Computing network centrality measures on fMRI data using fully weighted adjacency matrices

   University essay from Umeå universitet/Institutionen för datavetenskap

   Author : Stefan Bränberg; [2016]
   Keywords : ;

   Abstract : A lot of interesting research is currently being done in the field of neuroscience, a recent subject being the effort to analyse the the human brain connectome and its functional connectivity. One way this is done is by applying graph-theory based network analysis, such as centrality, on data from fMRI measurements. READ MORE

5. 4. Randomized word-parallel algorithms for detection of small induced subgraphs

   University essay from Lunds universitet/Institutionen för datavetenskap

   Author : David Larsson; Antonina Tokarchuk; [2015]
   Keywords : induced subgraph detection; word parallelism; randomization; Monte Carlo algorithms; practical approach; benchmarking; master’s thesis; Technology and Engineering; Mathematics and Statistics;

   Abstract : Induced subgraph detection is a widely studied set of problems in theoretical computer science, with applications in e.g. social networks, molecular biology and other domains that use graph representations. READ MORE
