Analysis of the shadow-sausage effect caustic.

چکیده
We analyze the optical caustic produced by light refracted at the curved meniscus surrounding a cylindrical rod standing partially out of a liquid-filled container. When the rod is tilted from the vertical or when light is diagonally incident, the caustic is a four-cusped astroid with two of its cusps obscured by the rod's shadow. If a portion of the flat end of the rod is raised above the water level, the caustic evolves into a pattern of five interlocking cusps. The five cusps result from symmetry breaking of a three-cusped surface perturbation caustic.

Combined effect of sodium polyphosphate and smoking on quality parameters of fish (Capoeta umbla) sausage
Improving food quality is one the major issues for the food processing industry. Since food produced from fish spoils quickly, it obviously cannot be kept for an extended time. The aim of the present study was to determine the effects of sodium polyphosphate and smoking on the shelf life of fish sausage that was produced from Capoeta umbla and stored at 4±1°C. Therefore, we designed four groups...
متن کاملAdaptive Caustic Maps Using Deferred Shading
Caustic maps provide an interactive image-space method to render caustics, the focusing of light via reflection and refraction. Unfortunately, caustic mapping suffers problems similar to shadow mapping: aliasing from poor sampling and map projection as well as temporal incoherency from frame-to-frame sampling variations. To reduce these problems, researchers have suggested methods ranging from ...
