Abstract: A method for modelling a scenario includes compiling a plurality of data sets; validating the plurality of data sets; determining model execution parameters for executing a set of models selected from among a plurality of models accessible to the modelling platform; automatically executing the set of models in accordance with the execution order to produce an output metric, where the output metric represents a cumulative result of execution of the set of models; creating a database record representative of the model execution parameters utilized to execute the set of models; and storing, by the one or more processors of the modelling platform, the database record in a database accessible to the modelling platform.

Abstract: A display device for creating animating images comprises a source of polarized light and first and second riffled reflecting means comprising a plurality of reflecting surfaces, placed in the path of light from said source of polarized light and arranged to reflect polarized light so as to transform the polarized light beam to a larger cross-section and through a polarizing screen to a diffusing surface.
