  2. 16. Monotonic and Semiparametric Regression for the Detection of Trends in Environmental Quality Data

    Author : Mohamed Hussian; Anders Grimvall; Ali Hadi; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Normalisation; Monotonic; Semiparametric; Temporal trends; fluctuations; global; local; Matematisk statistik; Icke-parametriska metoder; Statistics; Statistik;

    Abstract : Natural fluctuations in the state of the environment can long conceal or distort important trends in the human impact on our ecosystems. Accordingly, there is increasing interest in statistical normalisation techniques that can clarify the anthropogenic effects by removing meteorologically driven fluctuations and other natural variation in time series of environmental quality data.

  4. 17. Inference of systems-level behaviors in the immune system from single-cell data

    Author : Dieudonné Nkulikiyimfura; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Understanding the systems-level behaviours of the immune system requires profiling many parameters of its constituents as well as identifying environmental factors influencing the time evolution of immune response. Recent advances in technologies enable multiple cellular components to be measured simultaneously at an unprecedented scale and resolution across many individuals, and the resulting data could be used to meet this goal.

  5. 18. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness

    Author : Jonas Gillberg; Lennart Ljung; Fredrik Gustafsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete-time domain; Frequency-domain identification; Signal processing; Frequency-domain; Automatic control; Reglerteknik;

    Abstract : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. READ MORE

  6. 19. Regional differences in the response of neural stem cells and their microenvironment to ionizing radiation

    Author : Nina Hellström; Göteborgs universitet; []
    Keywords : ionizing radiation; neurogenesis; neural stem cells; inflammation; microglia; stem cell niche; trophic support;

    Abstract : Radiation therapy is one of the most effective tools for treating malignant tumors; however, cranial irradiation often results in intellectual impairment and cognitive deficits, such as impaired learning and memory. Ionizing radiation generates DNA damage, causing proliferative cells to undergo apoptosis. READ MORE

  7. 20. Control and Analysis of Pulse-Modulated Systems

    Author : Stefan Almér; Ulf Jönsson; Gilead Tadmor; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pulse-width modulation; Periodic systems; Stability analysis; Harmonic analysis; Lyapunov methods; Dynamic phasors; Harmonic transfer function; Switched mode power converters; Sampled data modeling; H-infinity synthesis; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. READ MORE
