A model for foot skin temperature prediction was evaluated on the basis of 2 experiments on subjects at various environmental temperatures (light seated manual work at -10.7 °C (Study 1), and a short walking period in combination with standing and sitting at +2.8 °C, -11.8 °C and -24.6 °C (Study 2), with boots of 3 insulation levels. Insulation of the footwear was measured on a thermal foot model.

This paper presents a dynamic optimization procedure of grade changes of polyethylene production. The optimization is built upon a novel modular Modelica library containing e.g., non-linear DAE models for polyethylene reactors based on models currently used in nonlinear MPC of industrial reactors at Borealis AB. Using Optimica, which extends the Modelica language with constructs for optimization p
Shopping has since long been recognized as a possible source of enjoyment. It has been argued that consumers of today devote ever more of their spare time to shopping. Within the domain of marketing, scholars have been successful in outlining consumers' motives for engaging in shopping as a leisure-time enjoyment.
