  2. 1. Semi Markov chain Monte Carlo

    Author : Håkan Ljung; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Adaptive simulation; error-in-the-variables; Kullback-Leibler divergence; Markov chain simulation; Markov chain Monte Carlo; semi-regenerative; MATEMATIK; MATHEMATICS; MATEMATIK; matematisk statistik; Mathematical Statistics;

    Abstract : The first paper introduces a new simulation technique, called semi Markov chain Monte Carlo, suitable for estimating the expectation of a fixed function over a distribution π, Eπf(χ). Given a Markov chain with stationary distribution p, for example a Markov chain corresponding to a Markov chain Monte Carlo algorithm, an embedded Markov renewal process is used to divide the trajectory into different parts.

  4. 2. Engraftment and tolerance induction in cellular therapy : focus on mesenchymal stromal cells

    Author : Karin Ljung; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Different cell types have been employed in the search for a cellular therapy that is applicable for the treatment of heart failure. Remuscularization strategies using stem-cell-derived cardiomyocytes have been prone to arrhythmias. READ MORE

  5. 3. Early diagnosis and risk stratification in patients with symptoms suggestive of acute coronary syndrome

    Author : Lina Ljung; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Chest pain is one of the most common symptoms in patients presenting to the emergency department (ED). Identifying the minority of patients with an acute coronary syndrome (ACS) is a challenge. The introduction of high-sensitivity cardiac troponin (hs-cTn T and I) assays has radically improved the assessment. READ MORE

  6. 4. Methods for robust gain scheduling

    Author : Anders Helmersson; Lennart Ljung; Linköpings universitet; []
    Keywords : ;

    Abstract : Regulatorer används i många tillämpningar för att förbättra prestanda ochegenskaper hos fordon och farkoster av olika slag, t ex flygplan och raketer.Beroende på olika faktorer, som hastighet och höjd, kan dynamiken ochuppträdandet av dessa farkoster variera. READ MORE

  7. 5. Experimental study of an intermittent ventilation system in high occupancy spaces

    Author : Alan Kabanshi; Patrik Sörqvist; Hans Wigö; Robert Ljung; Hazim Awbi; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.; Hållbar stadsutveckling; Sustainable Urban Development;

    Abstract : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. READ MORE
