  1. 1. A space-time shape for easier spatiotemporal visualization in traffic networks

    University essay from Uppsala universitet/Avdelningen för systemteknik

    Author : David Smeds; [2024]
    Keywords : ;

    Abstract : Modern big data systems are enabling new possibilities that never were thought possible in the past. The ability to gather massive data on an individual level has made fields like space-time geography bloom in the latest decennia. The usage of shapes in a 3D space allows us to visualize certain phenomena over time. READ MORE

  2. 2. And Action! : A Study of the Semantic Domains of Action through Interpretation of Metaphor

    University essay from

    Author : Henrik Westerdahl; [2023]
    Keywords : Semantic domain; Semantic dimension; Semantic pattern; Metaphor; Body in metaphor;

    Abstract : The aim of this essay is determining and describing some of the semantic domains of the concept of action. Action belongs to the type of abstract nouns with unclear semantic domains. In other words, there are difficulties in determining the precise semantic patterns that the word ‘action’ refers to. READ MORE

  3. 3. Wildlife-vehicle collisions : An evaluation of the mitigation effect by ecoducts and fauna bridges in Sweden

    University essay from Umeå universitet/Institutionen för geografi

    Author : Anna Rietz; [2023]
    Keywords : Space time pattern mining; Space time cube; Emerging hot spot analysis; Overlay analysis; Bivariate choropleth map; ArcGIS Pro; Wildlife-vehicle collision WVC ; Annual daily traffic;

    Abstract : The occurrence of wildlife vehicle collisions (WVCs) is an increasing problem in Sweden with a calculated increase of 45 percent from 2015 to 2022. The highest measured number of WVCs occurred in 2021 with over 67,000 reported incidents, where only the payment for the search of wounded animals were approximately 60 million Swedish crowns.

  4. 4. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
    Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

    Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

  5. 5. Black Hole Dynamics in Stellar Clusters

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Markus Strickert; [2022]
    Keywords : Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

    Abstract : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.
