Flow graph oriented testing is heavily used in industry, but has not yet been adapted to functional programming. Carrying over this approach from imperative programs to other programming paradigms consists of adapting the notion of flow graphs, and the identification of useful coverage criteria. The identification of coverage criteria is the topic of this paper. We define a number of data flow ...

The paper introduces hidden grid background oriented schlieren for quantitative study and visualization of natural convection heat transfer. In this technique, the refractive index variation, induced by temperature gradient, is encoded in recorded signal phase through distortion a pattern. (undistorted) pattern implicit (or hidden) light source. Quantitative estimation map obtained windowed Fou...
