  3. 2. Transceiver Design for Multiple Antenna Communication Systems with Imperfect Channel State Information

    Författare :Xi Zhang; Björn Ottersten; Miguel Lagunas; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MIMO; imperfect CSI; linear transceiver; beamforming; user selection; robust design; channel statistics; Telecommunication; Telekommunikation;

    Sammanfattning : Wireless communication links with multiple antennas at both the transmitter and the receiver sides, so-called multiple-input-multiple-output (MIMO)systems, are attracting much interest since they can significantly increase the capacity of band-limited wireless channels to meet the requirements of the future high data rate wireless communications. The treatment of channel state information (CSI) is critical in the design of MIMO systems. LÄS MER

  4. 3. Simulation-based Optimization and Decision Making with Imperfect Information

    Författare :Farzad Kamrani; Rassul Ayani; Stephen John Turner; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation-based Optimization; UAV Path Planning; Business Process Optimization;

    Sammanfattning : The purpose of this work is to provide simulation-based support for making optimal (or near-optimal) decisions in situations where decision makers are faced with imperfect information. We develop several novel techniques and algorithms for simulation-based optimization and decision support and apply them to two categories of problems: (i) Unmanned Aerial Vehicle (UAV) path planning in search operations, and; (ii) optimization of business process models.

  5. 4. Approaching well-founded comprehensive nuclear data uncertainties : Fitting imperfect models to imperfect data

    Författare :Petter Helgesson; Henrik Sjöstrand; Helmut Leeb; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Evaluated nuclear data; uncertainty propagation; uncertainty quantification; model defects; Gaussian processes; TALYS; TENDL; covariances.; Fysik med inriktning mot tillämpad kärnfysik; Physics with specialization in Applied Nuclear Physics;

    Sammanfattning : Nuclear physics has a wide range of applications; e.g., low-carbon energy production, medical treatments, and non-proliferation of nuclear weapons. Nuclear data (ND) constitute necessary input to computations needed within all these applications. LÄS MER

  7. 5. Electoral Incentives and Information Content in Macroeconomic Forecasts

    Författare :André Reslow; Mikael Carlsson; Jesper Lindé; Gisle James Natvik; Uppsala universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Brexit; Electoral Cycles; Forecast Evaluation; Forecasting; Imperfect Information; Interest Groups; Political Selection; Voting; Economics; Nationalekonomi;

    Sammanfattning : Essay I (with Davide Cipullo): This essay introduces macroeconomic forecasters as new political agents and suggests that they use their forecasts to influence voting outcomes. The essay develops a probabilistic voting model in which voters do not have complete information about the future economy and rely on professional forecasters when forming beliefs. LÄS MER
