  1. 16. Bit loading and precoding for MIMO communication systems

    Författare :Svante Bergman; Björn Marklund; Tim Davidsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : This thesis considers the joint design of bit loading, precoding and receive filters for a multiple-input multiple-output (MIMO) digital communication system. Both the transmitter and the receiver are assumed to know the channel matrix perfectly. It is well known that, for linear MIMO transceivers, orthogonal transmission (i.e. LÄS MER

  3. 17. Arkitekten och brukarmedverkan

    Författare :Ingrid Svetoft; Bengt Hansson; Inga Malmqvist; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; arkitektens roll; arkitektens utbildning; brukarmedverkan; byggprocess; designprocess; kommunikation; samspel; Building manufacturing engineering; Byggproduktionsteknik; byggprocess; designprocess; brukarmedverkan; Arkitektens roll; kommunikation; arkitektens utbildning; samspel;

    Sammanfattning : Working conditions and regulations encourage everyone to participate actively in shaping the surrounding environment in order to increase the social durability. End-users’ participation during the construction process will contribute to building better products that fulfil their needs and requirements. LÄS MER

  4. 18. Registered nurses' work motivation and intention to stay at the workplace

    Författare :Carina Ahlstedt; Anna Nyberg; Linda Moberg; Åsa Engström; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; registered nurse; work motivation; illegitimate tasks; social support; work environment; Hälso- och sjukvårdsforskning; Health Care Research;

    Sammanfattning : There is currently a shortage of registered nurses (RNs) and high turnover of RNs, both nationally and internationally. Work motivation is an important part of a healthy work environment and something we need to know more about from an RN perspective. LÄS MER

  5. 19. Upgrading chronic care : exploring challenges in rheumatology care management

    Författare :Helena Hvitfeldt Forsberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Introduction: The literature on chronic care describes a gap between what patients need and what healthcare provides. In rheumatoid arthritis, major medical advances have taken place in recent years which have made it possible to successfully treat more patients. LÄS MER

  7. 20. Design and Implementation of Efficient and Secure Lightweight Cryptosystems

    Författare :Shohreh Sharif Mansouri; Elena Dubrova; Vincent Rijmen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : In recent years there has been a wide-spread deployment of battery-powered and passive devices such as RFID tags, systems with very strong limitations on area, cost and power budgets. Deploying cryptographic solutions for these systems is both important, because it could unlock several security-critical applications, and challenging, due to the stringent budgets: the overheads of even the smallest block ciphers are often one or more orders of magnitude too high.
