  1. 1. Multiple Model Filtering and Data Association with Application to Ground Target Tracking

    Författare :Daniel Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multiple model filtering; semi-Markov processes; multi-target tracking; FISST; state estimation; IMM; performance evaluation; OSPA; PHD; ground target tracking; Kalman filtering; target tracking; CPHD; MHT; random finite sets;

    Sammanfattning : This thesis is concerned with two central parts of a tracking system, namely multiple-model filtering and data association. Multiple models are introduced to provide accurate filtering, whereas data association deals with the unknown origin of the received measurements. LÄS MER

  3. 2. A Signal Processing Approach to Practical Neurophysiology : A Search for Improved Methods in Clinical Routine and Research

    Författare :Björn Hammarberg; Dick Stegeman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemteknik; matched filter; asynchronous detection; Kalman filter; initialization; MHT; Wiener deconvolution; line source model; electromyography; needle EMG; motor unit potential; MUAP; mean fiber concentration; jitter; microneurography; C-fiber; spike sorting; Systemteknik; Systems engineering; Systemteknik; Signal Processing; signalbehandling;

    Sammanfattning : Signal processing within the neurophysiological field is challenging and requires short processing time and reliable results. In this thesis, three main problems are considered.First, a modified line source model for simulation of muscle action potentials (APs) is presented. LÄS MER

  4. 3. Epidemiological and Clinical Aspects of Hormonal Contraception and Menopausal Hormone Therapy in Women

    Författare :Micaela Sundell; Jan Brynhildsen; Anna-Clara Spetz Holm; Mats Fredrikson; Mikael Hoffmann; Ian Milsom; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hormonal contraceptives; Obesity; Menopausal hormone therapy; Hormone replacement therapy; Pulmonary embolism; Premature menopause; Pharmacoepidemiology;

    Sammanfattning : Background: The main indications for therapy with female sex hormones are contraception and menopausal hormone therapy (MHT). The aim of this thesis was to investigate the use of hormonal contraception and MHT in different populations of women in Sweden, 2000–2021. The use of contraception in women with obesity was studied.

  5. 4. The role of oestrogens and antibiotics on the development of cancer

    Författare :Johanna Simin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Despite advances in cancer treatment and surgery, cancer-related mortality remains the leading cause of death globally, harvesting over ten million lives annually. While the risk factors are both hormonal and non-hormonal, common prescription drugs’ long-term effects are understudied and likely even underestimated. LÄS MER

  7. 5. Female sex hormones and health outcomes in women with specific focus on asthma

    Författare :Guo-Qiang Zhang; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; asthma; Bayesian estimation; case-control; causal inference; estrogens; female sex hormones; hormonal contraceptives; menarche; menopausal hormone therapy; menopause; meta-analysis; multiple imputation; progestogens; research reproducibility; robust variance estimation; systematic review; umbrella review; women;

    Sammanfattning : In humans, gender differences exist across a wide spectrum of diseases. For instance, women are more likely to develop Sjogren’s syndrome, systemic lupus erythematosus, and autoimmune thyroid disease compared to men. LÄS MER
