is the average number of people infected from one other person. For example, Ebola has an of two, so on average, a person who has Ebola will pass it on to two other people.. In epidemiology, the basic reproduction number, or basic reproductive number (sometimes called basic reproduction ratio or basic reproductive rate), denoted (pronounced R nought or R zero), [1] of an infection is the ...
The Rossby number (Ro), named for Carl-Gustav Arvid Rossby, is a dimensionless number used in describing fluid flow. The Rossby number is the ratio of inertial force to Coriolis force , terms | v ⋅ ∇ v | ∼ U 2 / L {\displaystyle |\mathbf {v} \cdot \nabla \mathbf {v} |\sim U^{2}/L} and Ω × v ∼ U Ω {\displaystyle \Omega \times \mathbf ...
Once a sequence has a repeated value, the sequence will cycle, because each value depends only on the one before it. This structure of eventual cycling gives rise to the name "rho algorithm", owing to similarity to the shape of the Greek letter ρ when the values x 1 mod p {\displaystyle x_{1}{\bmod {p}}} , x 2 mod p {\displaystyle x_{2}{\bmod ...
Reproductive value is a concept in demography and population genetics that represents the discounted number of future female children that will be born to a female of ...
So, the RMS value, I RMS, of the function I(t) is the constant current that yields the same power dissipation as the time-averaged power dissipation of the current I(t). Average power can also be found using the same method that in the case of a time-varying voltage, V(t), with RMS value V RMS,

The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a material (e.g. for polyethylene foam), or for an assembly of materials (e.g. a wall or a window). In the case of materials, it is often expressed in terms of R ...
Not surprisingly, S E gives the same ordering of the main group elements as the electronegativity, though it differs in its numerical value from traditional electronegativity scales. Because it is defined in structural terms, S E is the preferred measure of electronegativity in the bond valence model, [ 9 ]
