CCDs are good imaging devices. However, a CCD can not easily integrate timing, control, A/D, or image processing logic on the same silicon die. They require an interface chip to operate, typically consume high power, and sometimes require odd voltages.
This means that imaging systems using a CCD are typically more expensive, physically larger in size, and consume more power. More.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
