    Asymptotic Fairness of Bonus-Malus Systems and Optimal Scales of Premiums

    In this paper we try to evaluate the asymptotic fairness of bonus-malus systems, assuming the simplest case when there is no hunger for bonus. The asymptotic fairness has to be understood as the bonus-malus sy...

    Temperature and pH-sensitive chitosan hydrogels: DSC, rheological and swelling evidence of a volume phase transition

    On heating, alkali chitin solutions undergo phase separation describing a characteristic “U-shaped” cloud point curve with a lower critical solution temperature (LCST) centered at ∼30 °C. The process is accomp...
