  1. 56. Single-User Receivers for Partly Known Interference in Multi-User Environments

    Författare :Bo Hagerman; Jens Zander; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cellular systems; mobile radio systems; co-channel interference; inter-cell interference; interference adaptive receiver; macrocells; microcells; Information technology; Informationsteknik; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : In multiuser environments such as cellular radio systems, the limited available bandwidth is one of the principal design constraints. For future high subscriber density systems, frequency reuse is one of the fundamental approaches for efficient spectrum utilization in order to meet the increased demands for capacity. LÄS MER

  3. 57. Data and Time Efficient Historical Document Analysis

    Författare :Florian Westphal; Håkan Grahn; Niklas Lavesson; Angelo Marcelli; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Systems Engineering; Datorsystemteknik;

    Sammanfattning : Over the last decades companies and government institutions have gathered vast collections of images of historical handwritten documents. In order to make these collections truly useful to the broader public, images suffering from degradations, such as faded ink, bleed through or stains, need to be made readable and the collections as a whole need to be made searchable.

  4. 58. Reconsidering the avatar : From user mirror to interaction locus

    Författare :Kai-Mikael Jää-Aro; Yngve Sundblad; Wolfgang Prinz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; virtual environments; computer-supported collaborative work; user representation; human-computer interaction;

    Sammanfattning : This thesis is concerned with shared virtual environmentsfor collaborative work. An important aspect of shared virtualenvironments is the avatar, the representation of the user inthe virtual world. LÄS MER

  5. 59. Database and Visualization for Advanced Systems Biology

    Författare :Natapol Pornputtapong; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; omic data visualization system; data standardization; data integration; database system; database design;

    Sammanfattning : In the information age, there is plenty of information available publicly in the field of biology. Utilization of biological data is still slow and inefficient compared to the amount of data generated. This problem arise due to the specific characteristics of biological data, which are complex, dynamic and variable. LÄS MER

  7. 60. Supporting Data Interaction and Hybrid Asymmetric Collaboration Using Virtual Reality Within the Context of Immersive Analytics

    Författare :Nico Reski; Aris Alissandrakis; Andreas Kerren; Petra Isenberg; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 3D gestural input; 3D radar charts; 3D user interfaces; empirical evaluation; head-mounted display; hybrid asymmetric collaboration; immersive analytics; spatio-temporal data interaction; user interface design; virtual reality; 3D-handinteraktion; 3D-radardiagram; 3D-användargränssnitt; design av användargränssnitt; empirisk utvärdering; huvudburen display; hybrid-asymmetrisk samarbete; immersiv analys; virtuell verklighet; Computer Science; Datavetenskap; Informations- och programvisualisering; Information and software visualization;

    Sammanfattning : Immersive display and interaction technologies have rapidly evolved in recent years, offering advanced techniques compared to traditional Human-Computer Interaction. Computer-generated Virtual Environments viewed with stereoscopic depth perception and explored using 3D spatial interaction can represent more accurately how humans naturally interact in the real world.
