  1. 1. Should I stay or should I go – Factors associated with hospitalization risk among older persons in Sweden

    Författare :Jenny Hallgren; Anna K. Dahl Aslan; Eleonor Fransson; Marie Elf; Jönköping University; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Older persons; hospitalization; risk factors; cognitive decline; qualitative content analyses; longitudinal; Cox regression; latent growth curve modelling;

    Sammanfattning : An increasingly older population will most likely lead to greater demands on the health care system, as older age is associated with an increased risk of having acute and chronic conditions. The number of diseases or disabilities is not the only marker of the amount of health care utilized, as persons may seek hospitalization without a disease and/or illness that requires hospital healthcare.

  2. 2. X-ray absorption spectroscopy through damped coupled cluster response theory

    Författare :Thomas Fransson; Patrick Norman; Lars Pettersson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : For a fundamental understanding of the interaction of electromagnetic radiation and molecular materials, experimental measurements are to be combined with theoretical models. With this combination, materials can be characterized in terms of composition, structure, time-resolved chemical reactions, and other properties. LÄS MER

  3. 3. Stochastic epidemics on random networks and competition in growth

    Författare :Carolina Fransson; Pieter Trapman; Daniel Ahlberg; Julia Komjathy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; random graphs; branching processes; SIR epidemics; malthusian parameter; urn model; matematisk statistik; Mathematical Statistics;

    Sammanfattning : The COVID-19 pandemic has dramatically demonstrated the importance of epidemic models in understanding and predicting disease spread and in assessing the effectiveness of interventions. The overarching topic of this thesis is stochastic epidemic modelling, with the main focus on the role of the underlying social structure in infectious disease spread. LÄS MER

  4. 4. Development of an Impinging Receiver for Solar Dish-Brayton Systems

    Författare :Wujun Wang; Björn Laumert; Torsten Fransson; Torsten Strand; Uwe Gampe; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concentrating solar power; Impinging receiver; Inverse design method; Conjugate heat transfer; High flux solar simulator; Energiteknik; Energy Technology;

    Sammanfattning : A new receiver concept utilizing impinging jet cooling technology has been developed for a small scale solar dish-Brayton system. In a typical impinging receiver design, the jet nozzles are distributed evenly around the cylindrical absorber wall above the solar peak flux region for managing the temperature at an acceptable level.

  5. 5. Design of Internal Cooling Passages: Investigation of Thermal Performance of Serpentine Passages

    Författare :Waseem Siddique; Torsten Fransson; Bengt Sundén; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gas turbine; heat transfer; CFD; Serpentine passages; SRA - Energy; SRA - Energi;

    Sammanfattning : Gas turbines are used to convert thermal energy into mechanical energy. The thermal efficiency of the gas turbine is directly related to the turbine inlet temperature. LÄS MER
