  1. 1. "Dom brukar jämföra det med en stridspilot" : en studie i organisationskommunikation

    Författare :Maria Högvall Nordin; Kristina Wallander; Margareta Barnekow-Bergkvist; Gunilla Jarlbro; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Organizational communication; risk communication; content analysis; conceptions; key symbols; work environment; forest work; forest machine contractors.; sense making; organizational field; case study; interviews; Media and communication studies; Medie- och kommunikationsvetenskap; forest machine contractors;

    Sammanfattning : The focus of this dissertation is on how communication regarding work environment and work related risks can be understood from an organizational communication perspective. Based on a case study of communication about work environment and work related risks in the Swedish forest industry, the present study discusses institutional influences on organizational sense making processes.

  2. 2. Ship and Society : Maritime Ideology in Late Iron Age Sweden

    Författare :Gunilla Larsson; Ola Kyhlberg; Mats G. Larsson; Uppsala universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Archaeology; Ships; Seafaring; Society; Late Iron Age; shipbuilding methods; symbols; sacrifices; boat burials; ideology; leiðangr; long distance journeys; river routes.; Arkeologi; Archaeology; Arkeologi;

    Sammanfattning : This thesis analyses the relation between ship and society against a background of ideological and technological changes in Late Iron Age Sweden. It discusses the factors behind the development of ‘a maritime society’, why ships and seafaring came to play an important role that was also reflected in the use of the ship as a symbol and a metaphor in a military context, as well as in religion, administration, jurisdiction and social life.

  3. 3. Med älgen i huvudrollen : Om fångstgropar, hällbilder och skärvstensvallar i mellersta Norrland

    Författare :Ylva Sjöstrand; Anders Andrén; Kerstin Cassel; Lise Nordenborg Myhre; Stockholms universitet; []
    Nyckelord :HUMANITIES; HUMANIORA; HUMANIORA; HUMANITIES; Stone Age; Northern Sweden; Nämforsen; rock art; pit falls; mounds of burnt stone; affordances; James J. Gibsson; chronology; theories of meaning; key symbols; neolithisation; arkeologi; Archaeology;

    Sammanfattning : The importance of the elk (Alces alces) in the Stone Age societies of northern Sweden constitutes the major focus of this thesis. The point of departure is a simple but crucial observation: this animal is the common denominator between the three stationary types of remains known in this region from the period 4000-1800 BC.

  4. 4. Short-Packet Communications: Fundamental Performance and Key Enablers

    Författare :Johan Östman; Chalmers University of Technology; []
    Nyckelord :NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Rayleigh fading; Block-fading channels; Rician fading; variable-length stop-feedback; short-packet channel codes.; ultra-reliable low-latency;

    Sammanfattning : The paradigm shift from 4G to 5G communications, predicted to enable new use cases such as ultra-reliable low-latency communications (URLLC), will enforce a radical change in the design of communication systems. Unlike in 4G systems, where the main objective is to have a large transmission rate, in URLLC, as implied by its name, the objective is to enable transmissions with low latency and, simultaneously, very high reliability.

  5. 5. Partial Response and Faster-than-Nyquist Signaling

    Författare :Fredrik Rusek; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Signalbehandling; Signal processing; Partial Response Signaling; Faster-than-Nyquist Signaling; Digital Communications; Coding Theory; Telekommunikationsteknik;

    Sammanfattning : Bandwidth efficiency is a key objective in the design of a digital communication system. Traditionally it is accomplished by increasing the constellation size of the signaling system. In this thesis alternative techniques are studied. Because the communication channel is continuous, so must the actual time signals be. LÄS MER
