3. 2. Exercise induced breathing problems in adolescents

   Författare :Henrik Johansson; Margareta Emtner; Christer Janson; Kai-Håkon Carlsen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Exercise; dyspnoea; bronchoconstriction; laryngeal obstruction; adolescents; HRQoL; physical activity; Lungmedicin; Lung Medicine;

   Sammanfattning : Experiencing respiratory symptoms in conjunction with exercise is common in children and adolescents and can have a negative impact on daily life. The aim of the thesis was to estimate the prevalence of exercise-induced dyspnoea, exercise-induced bronchoconstriction (EIB) and exercise-induced laryngeal obstruction (E-ILO) in a general adolescent population, and to explore factors associated with EIB.

5. 4. Recursive Methods in Urn Models and First-Passage Percolation

   Författare :Henrik Renlund; Sven Erick Alm; Svante Janson; John Wierman; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stochastic approximation algorithm; generalized Polya urn; limit theorem; first-passage percolation; rate of percolation; time constant; Mathematical statistics; Matematisk statistik; Mathematical Statistics; Matematisk statistik;

   Sammanfattning : This PhD thesis consists of a summary and four papers which deal with stochastic approximation algorithms and first-passage percolation. Paper I deals with the a.s. limiting properties of bounded stochastic approximation algorithms in relation to the equilibrium points of the drift function. LÄS MER

7. 5. Optimal Stopping and Model Robustness in Mathematical Finance

   Författare :Henrik Wanntorp; Johan Tysk; Svante Janson; Boualem Djehiche; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optimal stopping; model robustness; American options; free boundary problems; hedging; option pricing; Mathematical statistics; Matematisk statistik;

   Sammanfattning : Optimal stopping and mathematical finance are intimately connected since the value of an American option is given as the solution to an optimal stopping problem. Such a problem can be viewed as a game in which we are trying to maximize an expected reward. LÄS MER
