  2. 1. Facing Nature : Cultivating Experience in the Nature Connection Movement

    Author : Henrik Ohlsson; David Thurfjell; Cecilie Rubow; Kocku von Stuckrad; Södertörns högskola; []
    Keywords : HUMANIORA; HUMANITIES; face; facing; cultivation of experience; nature connection; nature connection movement; animism; compartmentalisation; de-compartmentalisation; hermeneutic phenomenology; Historical Studies; Historiska studier;

    Abstract : Through field research in Sweden and Finland between 2017 and 2022, the thesis follows a burgeoning social movement in which connection with nature is seen as a means of both personal wellbeing and ecological sustainability at the societal level. The thesis describes and analyses ideas, practices, organisations, and literature in a contemporary cultural context in the borderland between health practice, environmental activism, and spirituality.

  4. 2. Understanding therapeutic traditions in a multilevel framework - new methodological approaches

    Author : Henrik Ohlsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adherence to guidelines; practice variation; Multilevel models; variance components; determinants of prescription;

    Abstract : Background: The observation of differences in the way apparently similar patients are treated from one health care setting to another, i.e., practice variation, have been recognized in numerous studies. The variations across the health care settings have been shown to exist for different outcomes. READ MORE

  5. 3. Regression on Manifolds with Implications for System Identification

    Author : Henrik Ohlsson; Lennart Ljung; Jonas Mårtensson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; High-Dimensional Regression; Manifold; Gray-Box Identification.; Automatic control; Reglerteknik;

    Abstract : The trend today is to use many inexpensive sensors instead of a few expensive ones, since the same accuracy can generally be obtained by fusing several dependent measurements. It also follows that the robustness against failing sensors is improved. As a result, the need for high-dimensional regression techniques is increasing. READ MORE

  6. 4. Regularization for Sparseness and Smoothness : Applications in System Identification and Signal Processing

    Author : Henrik Ohlsson; Lennart Ljung; Jacob Roll; Bo Wahlberg; Linköpings universitet; []
    Keywords : Regularization; sparsity; smothness; lasso; l1; fMRI; bio-feedback; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In system identification, the Akaike Information Criterion (AIC) is a well known method to balance the model fit against model complexity. Regularization here acts as a price on model complexity. READ MORE

  7. 5. Studies on Design and Implementation of Low-Complexity Digital Filters

    Author : Henrik Ohlsson; Lars Wanhammar; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-complexity digital filters; lattice wave digital filters LWDFs ; digital down converter DDC ; analog-to-digital converters ADCs ; Signal processing; Signalbehandling;

    Abstract : In this thesis we discuss design and implementation of low-complexity digital filters. Digital filters are key components in most digital signal processing (DSP) systems and are, for example, used for interpolation and decimation. READ MORE
