If you mean any other sort of "quality" then you need to come up with a better definition of quality. For example, over-exposure may be a problem in which case hunting for saturated pixels would help determine that specific sort of quality. Or more generally you could look at statistics (mean, standard deviation) of the image histogram in the 3 ...
The better the quality of the articles that you use in the literature review, the stronger your own research will be. When you use articles that are not well respected, you run the risk that the conclusions you draw will be unfounded. Your supervisor will always check the article sources for the conclusions you draw. We will use an example to explain how you can judge …
Some common problems with photocells include cracks appearing due to extreme weather, or loose wiring, or even debris accumulating in the photocells. By ensuring secure and tight wiring, keeping the photocell units free of debris and by choosing weather resistant, high quality units, you can avoid these problems and ensure consistent light.

Photocells are made of a semiconductor material that absorbs photons of light and generates an electric charge, which affects the conductivity of the material. The basic principle of a photocell is that when light falls on its surface, it causes the electrons in the semiconductor material to move from the valence band to the conduction band, creating a flow …
