  1. 31. Interactions between Polymers in Dispersion Coating and Surface Sizing of Paper and Board

    Författare :Caisa Johansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Engineering; Kemiteknik;

    Sammanfattning : Barrier dispersion coatings are applied to paper or board in order to lower the permeability of the material to liquids and gases. In the present study, the film formation and barrier properties of latices used for coating applications were investigated. LÄS MER

  3. 32. Utilization of tax allowances and corporate borrowing

    Författare :Gunnar Forsling; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Economics; Nationalekonomi; Economics; Nationalekonomi; nationalekonomi; Economics;

    Sammanfattning : This thesis consists of three self-contained essays on corporate taxation.Essay I is a descriptive analysis of the utilization of tax allowances by Swedish tax-paying firms. We conclude that firms have systematically failed to take full advantage of the allowances granted by the government. LÄS MER

  4. 33. Optimization of LDMOS Transistor in Power Amplifiers for Communication Systems

    Författare :Ahsan-Ullah Kashif; Qamar-ul Wahab; Christer Svensson; Joachim Wurfl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RF-LDMOS; power amplifiers; technology CAD; load-pull; non-linear analysis; and switching analysis; Semiconductor physics; Halvledarfysik;

    Sammanfattning : The emergence of new communication standards has put a key challenge for semiconductor industry to develop RF devices that can handle high power and high data rates simultaneously. The RF devices play a key role in the design of power amplifiers (PAs), which is considered as a heart of base-station. LÄS MER

    Författare :Ionel Octavian Savu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Chronic complications of diabetes represent a major medical and economical concern. It is an imperative need to establish the pathogenic mechanisms that contribute to development of chronic complications in order to design new therapeutic approaches. LÄS MER

  7. 35. Beyond Massive MIMO : Trade-offs and Opportunities with Large Multi-Antenna Systems

    Författare :Juan Vidal Alegría; Kommunikationsteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; massive MIMO; cell-free massive MIMO; Decentralized multi-antenna architectures; Decentralized schemes; WAX decomposition; LIS; Reconfigurable surfaces; RIS; IRS; ARIS; FRIS;

    Sammanfattning : After the commercial emergence of 5G, the research community is already putting its focus on proposing innovative solutions to enable the upcoming 6G. One important lesson put forth by 5G research was that scaling up the conventional multiple-input-multiple-output (MIMO) technology by increasing the number of antennas could be extremely beneficial for effectively multiplexing data streams in the spatial domain.
