See your GP if you have: 1  persistent or worrying symptoms that could be caused by haemochromatosis â particularly if you have a northern European family background. 2  a parent or sibling with haemochromatosis, even if you don't have symptoms yourself â tests can be done to check if you're at risk of developing problems.
The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure 1).
This can be done with either a sky view factor or a diffuse shading coefficient. The sky view factor is the view factor from the surface to the sky. This is the ratio of the diffuse sky radiation received by the surface to that which would be received by the same surface if it were completely exposed to the sky.
