  1. 1. Mimetiskt syskonskap : En representationsteoretisk undersökning av relationen fiktionsprosa-fiktionsfilm

    Författare :Christer Johansson; Göran Rossholm; Greger Andersson; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; semiotics; narratology; literary theory; film theory; aesthetic theory; representation; medium; fictionality; narrative; meaning; intermediality; iconicity; indexicality; metaphor; narrative perspective; fiction; film; Literature; Litteraturvetenskap; litteraturvetenskap; Literature;

    Sammanfattning : The dissertation deals with two different subjects: on the one hand the interrelations of narrative prose fiction and narrative fiction film, on the other hand fictional narration and intermediality as such. The first part discusses the concepts of medium and intermediality, and presents some general theoretical models. LÄS MER

    Sammanfattning : The requirements for next-generation wireless communications networks, particularly fifth-generation (5G) and beyond, are driven by at least three broad use cases. These include enhanced mobile broadband services to support extremely high data rates in terms of network or per user in both uplink and downlink, massive machine-type communications to accommodate massive internet-of-things applications, and critical machine-type communications to handle mission-critical applications that require ultra-high reliability and low latency.

  4. 3. Studies in knowledge representation : modeling change - the frame problem : pictures and words

    Författare :Lars-Erik Janlert; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analogical; artificial intelligence; digital; exemplification; frame problem; Goodman; knowledge representation; metaphysics; model; pictorial representation; symbol theory;

    Sammanfattning : In two studies, the author attempts to develop a general symbol theoretical approach to knowledge representation.The first study, Modeling change -the frame problem, critically examines the - so far unsuccessful - attempts to solve the notorious frame problem. LÄS MER

  5. 4. Den nya stadens bibliotek : Om teknik, förnuft och känsla i gestaltningen av kunskaps- och upplevelsestadens folkbibliotek

    Författare :Hanna Carlsson; Olof Sundin; Jenny Johannisson; Nanna Kann-Rasmussen; digitala kulturer samt förlags- och bokmarknadskunskap Avdelningen för ABM; []

    Sammanfattning : The mobile industry is preparing to scale up the network capacity by a factor of 1000x in order to cope with the staggering growth in mobile traffic. As a consequence, there is a tremendous pressure on the network infrastructure, where more cost-effective, flexible, high speed connectivity solutions are being sought for. LÄS MER
