This is the collection of quantities that have a numeric component and could actually be used to measure something, as opposed to (say) merely ranking it on a scale. Arithmetic operations (such as addition and multiplication) can be performed on measurable quantities, as they can on purely numeric scalars (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rnVZQSiCmEdaAAACgyZzFrg" class="cyc_term">NumericInterval</a>).

In CycL, particular measurable quantities are usually represented as the result of applying a unit-of-measure function to a real number or pair of reals. For example, (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVjRp5wpEbGdrcN5Y29ycA" class="cyc_term">Meter</a> 5) is the distance 5 meters.

Every complex number can be represented as a + ib where i is the square root of negative one (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvx4CzZwpEbGdrcN5Y29ycA" class="cyc_term">I_TheNumber</a>), and a and b are reals (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvViAmJwpEbGdrcN5Y29ycA" class="cyc_term">RealNumber</a>). When b=0, the complex number has no imaginary part, and therefore is a real number. When b is not zero the complex number has an imginary part and so it is an imaginary number (see <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rwL5mhJwpEbGdrcN5Y29ycA" class="cyc_term">ImaginaryNumber</a>).

The unit value on the real number line is 1, the unit value on the imaginary number line is the square root of -1, generally written 'i' in mathematics and 'j' in engineering. ComplexNumber

It is used to represent the standard unit of CPU capacity -- millions of (machine-code) instructions per second. (<a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVi7MZwpEbGdrcN5Y29ycA" class="cyc_term">MIPS</a> 34.0) would represent a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvVkMiJwpEbGdrcN5Y29ycA" class="cyc_term">CPUSpeed</a> of around 34 million instructions per second. It has been argued that this benchmark is "completely pointless", since no two chips use exactly the same set of instructions, and the same set of instructions can do vastly more work depending on the chip size and the way the processing task has been structured. (For example, on a chip with <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rvw_evnS_EdaAAACgyZzFrg" class="cyc_term">CISCArchitecture</a>, a single instruction may do many things when executed, whereas on a <a href="http://sw.opencyc.org/2008/06/10/concept/Mx4rGkbP8nS9EdaAAACgyZzFrg" class="cyc_term">RISCArchitecture</a> chip it may do very little but be dealt with more efficiently).

This can include any kind of network; specs of this collection will refer to particular kinds of networks (e.g. computer network, phone network, communications network, network of safehouses) where the traffic is understood as being whatever moves through the network. Note that traffic is not cumulative in the following sense: the fact that one network has high traffic does not mean that any larger networks of which it is part do.

poise The poise is unit of dynamic viscosity in the CGS system. A poise is equal to the viscosity of a fluid that would require a shearing force of one dyne to move a square-centimeter area of one of two parallel layers of fluid one centimeter, with a velocity of one centimeter per second, relative to the other layer. In other words, it is the ratio of the shear stress to the shear rate of a fluid, expressed in dyne seconds per square centimeter.
