The law of cosine is also known as the cosine rule. This law is useful to find the missing information in any triangle. For example, if you know the lengths of two sides of a triangle and anangleincluded between them, this rule helps to find the third side of the triangle. Let us c...

Thus, as more and more flux is reflected from the front of the sheet, more and more will be transmitted through its edge, since in this case the incidence angle is decreasing and the exposed area incrases. At an 80° angle of incidence, for example, little flux will enter through the ...
(20.23) is a formula for the inverse Fourier transform. Note that the regular (“direct”) and inverse Fourier transforms are given by very similar (but not quite identical) formulas. The only difference is in the sign of the complex exponential. This change of sign causes two successive ...

the watermark bits cannot be embedded in the high-frequency dct parts because all these coefficients are highly quantized throughout data compression. as a rule, embedding the watermark in the middle-frequency domain is preferable. to further explain the embedding process, assume that the input of...
The formula for calculating A is as follows:(3)A=2*1-tMaxiter Depending on sech(hyperbolic tangent reciprocal function), it is related to the fitness value of the individual and the best fitness value (BF).(4)E=sechFi-BF BF represents the best fitness value obtained in the current itera...
