  1. 1. Application-level Chaos Engineering

    Författare :Long Zhang; Martin Monperrus; Benoit Baudry; Leon Moonen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dynamic analysis; software resilience; chaos engineering; Datalogi; Computer Science;

    Sammanfattning : With the development of software techniques, software systems nowadays are becoming highly complex. In order to keep such systems as reliable as possible, developers need to design various error-handling mechanisms. LÄS MER

  3. 2. Dynamics and Applications of Long Josephson Junctions

    Författare :Yongming Zhang; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The first object of this work is to theoretically study the effects of tunnel junction parameters on flux-flow Josephson oscillators (FFOs) by numerical simulation and to experimentally study the rf properties of FFOs by integrating them together with an SIS (superconductor-insulator-superconductor) mixer/detector on a chip. By using a CAD modeled integrated sub-mm wave receiver, the composite linewidth of two FFOs was measured to be less than 2. LÄS MER

  4. 3. Developmental trajectories of attention-deficit/hyperactivity disorder into adulthood and aging : multimorbidity and polypharmacy

    Författare :Le Zhang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder characterized by developmentally inappropriate levels of inattentiveness, hyperactivity, and impulsivity. Previous studies have shown that symptoms of ADHD often persist into adulthood. LÄS MER

  5. 4. Cytokine induced airway hyperreactivity characterized in an in-vitro model of asthma

    Författare :Yaping Zhang; Klinisk och experimentell allergiforskning; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; toxicology; Farmakologi; farmakognosi; MAPK; TNF-alpha; 5-HT; Respiratory system; Andningsorganen; Pharmacological sciences; pharmacognosy; pharmacy; interleukin-1beta; hyperresponsiveness; endothelin-1; airway; bradykinin; toxikologi; farmaci;

    Sammanfattning : Asthma is a chronic disorder of the lower airways, characterized by inflammation and hyperreactivity. Pro-inflammatory cytokines like tumour necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta) are known to play important roles in the pathogenesis, but our knowledge how these cytokines contribute to the development of airway hyperreactivity is limited.

  7. 5. Applications of artificial neural networks for time series data analysis in energy domain

    Författare :Fan Zhang; Hasan Fleyeh; Stawomir Nowaczyk; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Deregulated energy market; electricity prices; district heating; energy efficiency; neural networks; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : With the development of artificial intelligence techniques and increased installation of smart meters in recent years, time series analysis using historical data in the energy domain becomes applicable. In this thesis, microdata analysis approaches are used, which consist of data acquisition, data processing, data analysis and data modelling, aiming to address two research problems in the energy domain.
