Transformer Installation Rules
Some of the particularly important transformer installation rules are listed below.

Annualized standard deviation ...yes!
Okay, so the decision has been made: effective January 2011, GIPS compliant firms must report a 36-month annualized standard deviation, on an annual basis (that is, for all years starting with 2011).
Further clarity is in order.

Optics for Passive Radiative Cooling
Optics for Passive Radiative Cooling

Radiative cooling is the process by which a body loses heat by radiation. The spectrum and intensity of this thermal radiation, called blackbody radiation, depend on the temperature of the body
emitting it.

Complex Numbers: Subtraction, Division

From: April
Subject: Subtraction and division for imaginary numbers
I know that when adding imaginary numbers the formula is
(a+bi)+(c+di) = (a+c)+(b+d)i
but for subtraction, is the formula (a+c)-(b+d)i ?
