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

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

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

    Abstract : 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.

  3. 2. Generating a CBLS Invariant Structure from a FlatZinc Model

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Max Perea Düring; [2021]
    Keywords : combinatorial optimisation MiniZinc CBLS constraint model local search solver invariant structure;

    Abstract : Constraint-Based Local Search (CBLS) is a technology used to solve computationally hard optimisation problems. A model written in a solver-independent modelling language needs to be processed before it can be solved by a CBLS solver. In this processing step, it is necessary to identify invariants and create an invariant structure. READ MORE

  4. 3. Construction of Superimposed Codes Using Graphs and Galois Fields

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : David Johansson; [2017]
    Keywords : ;

    Abstract : In this thesis some constructions of superimposed codes are presented. Many of the known nontrivial constructions arise from t−designs, and the constructions discussed in this thesis is also based on a block design idea. Superimposed codes are rather combinatorial in nature, so the connection to t−designs is not too surprising. READ MORE

  5. 4. Synthesis of thin films of the Olivines Fe2SiS4 and Mn2SiS4 by magnetron sputtering and annealing

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joakim Eriksson; [2017]
    Keywords : photovoltaic; solar cell; thin film; semiconductor; absorber; abundant; olivine; ternary metal chalcogenides; manganese silicon sulfide; Mn2SiS4; iron silicon sulfide; Fe2SiS4; reactive magnetron sputtering; sulfurization; annealing; composition gradient; combinatorial; SEM; EDS; XRD; oxidation;

    Abstract : The photovoltaic industry attracts a lot of interest from researchers worldwide due to active integration of the solar cells. The main idea here is to convert solar energy into electricity. One type of solar cell that shows potential in replacing today’s crystalline silicon cells is the thin film solar cell (TFSC).

  6. 5. A thesis submitted in fulfilment of the requirements for the degree of Masters of Mathematics

    University essay from KTH/Matematik (Avd.)

    Author : Ofir Ammar; [2015]
    Keywords : ;

    Abstract : An open problem introduced by J. Haglund was to find a bijective proof over Dyck paths that would interchange two of its statistics. This problem was known to be The Symmetry Problem of the q,t-Catalan polynomial and was proven by other means to be true. READ MORE
