Spurious caustics of dispersion-relation-preserving schemes
A linear dispersive mechanism leading to a burst in the L∞ norm of the error in numerical simulation of polychromatic solutions is identified. This local error pile-up corresponds to the existence of spurious caustics, which are allowed by the dispersive nature of the numerical error. From the mathematical point of view, spurious caustics are related to extrema of the numerical group velocity a...
متن کاملA linear dispersive mechanism for numerical error growth: spurious caustics
A linear dispersive mechanism for error focusing in polychromatic solutions is identified. This local error pile-up corresponds to the existence of spurious caustics, which are allowed by the dispersive nature of the numerical error. ¿From the mathematical point of view, spurious caustics are related to extrema of the numerical group velocity. Several popular schemes are analyzed and are shown ...
متن کاملStylized Caustics: Progressive Rendering of Animated Caustics
In recent years, much work was devoted to the design of light editing methods such as relighting and light path editing. So far, little work addressed the target-based manipulation and animation of caustics, for instance to a differently-shaped caustic, text or an image. The aim of this work is the animation of caustics by blending towards a given target irradiance distribution. This enables an...

متن کاملSpurious Hyperleukocytosis
Hyperleukocytosis is an oncological emergency but is extremely rare in non-malignant conditions. Nucleated RBCs give rise to spuriously high total leucocyte count and cause clinical dilemma. Thalassemia major patients are known to have leucocytosis even after correction for nucleated RBCs. We report a case of undiagnosed Thalassemia major in a 4 month old infant with total leucocyte count highe...
