  1. 1. The Maximum Principle for Cauchy-Riemann Functions and Hypocomplexity

    Författare :Abtin Daghighi; Stefan Borell; Christer Kiselman; Egmont Porten; Juergen Leiterer; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hypocomplexity; hypoanalytic structure; CR functions; maximum principle; weak pseudoconcavity;

    Sammanfattning : This licentiate thesis contains results on the maximum principle forCauchy–Riemann functions (CR functions) on weakly 1-concave CRmanifolds and hypocomplexity of locally integrable structures. Themaximum principle does not hold true in general for smooth CR functions,and basic counterexamples can be constructed in the presenceof strictly pseudoconvex points. LÄS MER

  3. 2. Studies of distributions in physics using maximum entropy and scaling methods

    Författare :Lotten Hägg; Uppsala universitet; []
    Nyckelord :Maximum Entropy; Scaling Methods; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The maximum entropy method (MEM) is applied in the analysis of equilibrium systems. Some general properties of the MEM and how to choose constraints as well as moments are discussed. A numerically stable algorithm is developed and implemented. Distributions arising from physical processes are studied. LÄS MER

  4. 3. Contributions to the Stochastic Maximum Principle

    Författare :Daniel Andersson; Boualem Djehiche; Fred Espen Benth; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    Sammanfattning : This thesis consists of four papers treating the maximum principle for stochastic control problems. In the first paper we study the optimal control of a class of stochastic differential equations (SDEs) of mean-field type, where the coefficients are allowed to depend on the law of the process.

  5. 4. Analysis of Relay Channels and Improved Iterative Decoders for Turbo-Coded Decode-and-Forward Relay Channels

    Författare :Khoa Huynh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; detect-and-forward; maximum a posteriori; decode-and-forward; Maximum likelihood; iterative decoder.; relay channels; equivalent SNR; upper bound;

    Sammanfattning : Three-node relay channels which consist of a source, a relay and a destinationare considered in this thesis. In the first part, an uncoded relay channelis studied. LÄS MER

  7. 5. Maximum spacing methods and limit theorems for statistics based on spacings

    Författare :Magnus Ekström; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Estimation; spacings; maximum spacing method; consistency; ^-divergence; goodness of fit; unimodal density; entropy estimation; uniform distribution;

    Sammanfattning : The maximum spacing (MSP) method, introduced by Cheng and Amin (1983) and independently by Ranneby (1984), is a general estimation method for continuous univariate distributions. The MSP method, which is closely related to the maximum likelihood (ML) method, can be derived from an approximation based on simple spacings of the Kullback-Leibler information. LÄS MER
