  3. 17. Algorithmic Graph Problems - From Computer Networks to Graph Embeddings

    Författare :Martin Wahlén; Data Vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Approximation Algorithms; Exact Algorithms; Time Complexity; Broadcasting;

    Sammanfattning : This dissertation is a contribution to the knowledge of the computational complexity of discrete combinatorial problems. 1. The first problem that we consider is to compute the maximum independent set of a box graph, that is, given a set of orthogonal boxes in the plane compute the largest subset such that no boxes in the subset overlap.

  4. 18. Splitting rocks: Learning word sense representations from corpora and lexica

    Författare :Luis Nieto Piña; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; language technology; natural language processing; distributional models; semantic representations; distributed representations; word senses; embeddings; word sense disambiguation; linguistic resources; corpus; lexicon; machine learning; neural networks;

    Sammanfattning : The representation of written language semantics is a central problem of language technology and a crucial component of many natural language processing applications, from part-of-speech tagging to text summarization. These representations of linguistic units, such as words or sentences, allow computer applications that work with language to process and manipulate the meaning of text. LÄS MER

  5. 19. Lipid Nanotube Networks: Shape Transitions and Insights into the Dynamics of Self-Organization

    Författare :Tatsiana Lobovkina; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular nanotube; shape transition; enzymatic reaction; nanotube knot; self-organization; liposome; lipid nanotube; lipid vesicle; nanotube-vesicle network;

    Sammanfattning : Nanotube-vesicle networks (NVNs) are simplified models of cell membrane tubular systems which are dynamic transportation routs for molecular cargoes in biological cells. The presented work describes dynamic properties of NVNs such as self-organization, shape and topology transformations; moreover, specific geometric properties of the networks are used for controlling enzymatic reactions.

  7. 20. Towards Realistic Hyperon Reconstruction in PANDA : From Tracking with Machine Learning to Interactions with Residual Gas

    Författare :Adeel Akram; Karin Schönning; Michael Papenbrock; Carl Nettelblad; Andreas Salzburger; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hyperons; Clusterjet Target; Tracking; Graph Neural Networks; Deep Learning; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Sammanfattning : The PANDA (anti-Proton ANnihilation at DArmstadt) experiment at FAIR (Facility for Anti-proton and Ion Research) aims to study strong interactions in the confinement domain. In PANDA, a continuous beam of anti-protons will impinge on a fixed hydrogen target inside the High Energy Storage Ring (HESR), a feature intended to attain high interaction rates for various physics studies e.
