  3. 2. Intelligent System Designs : Data-driven Sensor Calibration & Smart Meter Privacy

    Författare :Yang You; Tobias J. Oechtering; Olga Fink; KTH; []
    Nyckelord :Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Nowadays, the intelligent system has gained high popularity in successful implementation of real-time tasks due to its capability of providing efficient and powerful decision making in real applications. In this thesis, we aim for exploring and exploiting different concepts or methods to handle different tasks towards the intelligent system design. LÄS MER

  4. 3. Designing Space-Time Codes Using Orthogonal Designs

    Sammanfattning : This thesis deals with coding schemes for systems with multiple transmit antennas. The problem of finding optimal transmission schemes for the case when the transmitter knows the channel and the case when the transmitter does not know the channel are considered. LÄS MER

  5. 4. On unequal probability sampling designs

    Författare :Anton Grafström; Lennart Bondesson; Sara De Luna; Imbi Traat; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; conditional Poisson sampling; correlated Poisson sampling; entropy; extended Sampford sampling; Horvitz-Thompson estimator; inclusion probabilities; list-sequential sampling; non-rejective implementation; Pareto sampling; Poisson sampling; probability functions; ratio estimator; real-time sampling; repeated Poisson sampling; Sampford sampling; sampling designs; splitting method; unequal probability sampling; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Sammanfattning : The main objective in sampling is to select a sample from a population in order to estimate some unknown population parameter, usually a total or a mean of some interesting variable. When the units in the population do not have the same probability of being included in a sample, it is called unequal probability sampling. LÄS MER

  7. 5. Optimal adaptive designs and adaptive randomization techniques for clinical trials

    Författare :Yevgen Ryeznik; Warwick Tucker; Andrew Hooker; Franz König; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; optimal designs; optimal adaptive designs; randomization in clinical trials; restricted randomization; adaptive randomization; unequal cost; allocation ratio preserving randomization procedures; heterogeneous costs; multi-arm clinical trials; randomization-based inference; unequal allocation; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : In this Ph.D. thesis, we investigate how to optimize the design of clinical trials by constructing optimal adaptive designs, and how to implement the design by adaptive randomization. LÄS MER
