  2. 16. Modeling of bacterial DNA patterns important in horizontal gene transfer using stochastic grammars

    Author : Mariana Buongermino Pereira; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Stochastic context-free grammars; hidden Markov model; conditional random fields; integrons; attC sites; secondary structure.; secondary structure.;

    Abstract : DNA contains genes which carry the blueprints for all processes necessary to maintain life. In addition to genes, DNA also contains a wide range of functional patterns, which governs many of these processes. These functional patterns have typically a high variability, both within and between species, which makes them hard to detect. READ MORE

  4. 17. Methodology for Handling Missing Data in Nonlinear Mixed Effects Modelling

    Author : Åsa M. Johansson; Mats O. Karlsson; Andrew C. Hooker; Leon Aarons; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmacometrics; population models; censored observations; missing covariates; missing dependent variable; missing data mechanism; missing completely at random MCAR ; missing at random MAR ; missing not at random MNAR ; estimation algorithms; Pharmaceutical Science; Farmaceutisk vetenskap;

    Abstract : To obtain a better understanding of the pharmacokinetic and/or pharmacodynamic characteristics of an investigated treatment, clinical data is often analysed with nonlinear mixed effects modelling. The developed models can be used to design future clinical trials or to guide individualised drug treatment. READ MORE

  5. 18. Model Error Compensation in ODE and DAE Estimators : with Automotive Engine Applications

    Author : Erik Höckerdal; Erik Frisk; James Peyton-Jones; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Information technology; Informationsteknik; Automatic control; Reglerteknik;

    Abstract : Control and diagnosis of complex systems demand accurate information of the system state to enable efficient control and to detect system malfunction. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. READ MORE

  6. 19. Conformal Maps, Bergman Spaces, and Random Growth Models

    Author : Alan Sola; Haakan Hedenmalm; Robert Berman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Conformal maps; Bergman kernels; planar growth models; MATHEMATICS; MATEMATIK;

    Abstract : This thesis consists of an introduction and five research papers on topics related to conformal mapping, the Loewner equation and its applications, and Bergman-type spaces of holomorphic functions. The first two papers are devoted to the study of integral means of derivatives of conformal mappings. READ MORE

  7. 20. Random and Hybrid Medium Access for M2M Communication : Scalability and Energy Analysis

    Author : Luca Beltramelli; Mikael Gidlund; Patrik Österberg; Aamir Mahmood; Preben Mogensen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; M2M; LoRa; IEEE 802.1ah; energy; mathematical modeling;

    Abstract : The term machine-to-machine (M2M) communication identifies any fully automated communication between intelligent devices, autonomous from human intervention. M2M communication is a key enabling technology for the Internet of Things (IoT), where it is used to provide ubiquitous connectivity between a large number of intelligent devices. READ MORE
