A Hybrid Model for the Financial Industry

An objective method to associate local weather extremes

Local weather extremes, like heavy rainfall or extreme temperatures, are usually connected to characteristic circulation patterns in the atmosphere. The figure below illustrates this fact for daily mean temperatures in July and August as observed in De Bilt. For  two periods with extreme high temperatures the atmospheric circulation deviation from the time-mean flow as characterizedView problem details

Mixing and Modelling: How Mathematics may mix Molecules

Introduction. Albemarle is a big chemical concern with about 3700 employees and many plants  worldwide. It is a manufacturer of polymers and fine chemicals, including additives and intermediates used in agricultural and cleaning products, drilling compounds, etcetera. Since mixing of different chemical compounds is one of its core techniques, Albemarle  Research in Amsterdam (former AkzoView problem details

Parametric roll of ships

Introduction ‘Parametric roll’ is a phenomenon that sometimes suddenly occurs to ships sailing in head or following seas. Apparently without any clear reason, the amplitude of the roll motion (i.e. the rotation about the longitudinal axis of the ship) increases within a couple of roll periods, from a few degrees to above 45 degrees. TheseView problem details

Stiffening While Drying

Stiffening While Drying DSM, Geleen Shared Research Unit Performance Materials Introduction Nowadays waterborne coatings (WBC’s) are increasingly replacing traditional organic solvent-borne coatings (SBC’s) in many applications due to stricter legislation originating from an ever-growing environmental awareness in society. One of the few disadvantages of WBC’s is that they generally require longer drying times as comparedView problem details
