In a third layer, the logarithms of rational numbers r = a / b are computed with ln(r) = ln(a) − ln(b), and logarithms of roots via ln n √ c = 1 / n ln(c).. The logarithm of 2 is useful in the sense that the powers of 2 are rather densely distributed; finding powers 2 i close to powers b j of other numbers b is comparatively easy, and series representations of ln(b) are ...
A plot of a typical log wind profile under statically neutral conditions. The roughness length plays a part in determining the slope of the line.. Roughness length is a parameter of some vertical wind profile equations that model the horizontal mean wind speed near the ground.
The log wind profile is a semi-empirical relationship commonly used to describe the vertical distribution of horizontal mean wind speeds within the lowest portion of the planetary boundary layer.
The red section on the right, d, is the difference between the lengths of the hypotenuse, H, and the adjacent side, A.As is shown, H and A are almost the same length, meaning cos θ is close to 1 and θ 2 / 2 helps trim the red away.
Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.
In 2009, it was shown that 2k / (2m – 3) must be a convergent of ln(2); in what the authors of that paper call "one of very few instances where a large scale computation of a numerical constant has an application", it was then determined that m > 2.7139 × 10 1,667,658,416. [1] In 2010, it was shown that [7] m ≡ 3 (mod 8) and m ≡ ±1 (mod ...

A fundamental property of Oseen's equation is that the general solution can be split into longitudinal and transversal waves.. A solution (, ′) is a longitudinal wave if the velocity is irrotational and hence the viscous term drops out.
