The field of slope stability encompasses the analysis of static and dynamic stability of slopes of earth and rock-fill dams, slopes of other types of embankments, excavated slopes, and natural slopes in soil and soft rock. [18] As seen to the right, earthen slopes can develop a cut-spherical weakness zone.
The slope number of a graph is the minimum number of distinct edge slopes needed in a drawing with straight line segment edges (allowing crossings). Cubic graphs have slope number at most four, but graphs of degree five may have unbounded slope number; it remains open whether the slope number of degree-4 graphs is bounded. [12]
FBI sketch of D. B. Cooper from 1972 compared to 1970 Army ID picture of Robert Rackstraw Robert Wesley Rackstraw (1943–2019) was a retired pilot and ex-convict who served on an Army helicopter crew and other units during the Vietnam War.
If we draw a graph of the logistic map (), we can observe that the slope of the tangent at the fixed point exceeds 1 at the boundary = and becomes unstable. At the same time, two new intersections appear, which are the periodic points x f 1 ( 2 ) {\displaystyle x_{f1}^{(2)}} and x f 2 ( 2 ) {\displaystyle x_{f2}^{(2)}} .
SketchUp was developed by startup company @Last Software of Boulder, Colorado, co-founded in 1999 by Brad Schell and Joe Esch. [5] [6] SketchUp was created in August 2000 as a 3D content creation tool and was envisioned as a software program for design professionals. [3]
By the Kelvin–Stokes theorem we can rewrite the line integrals of the fields around the closed boundary curve ∂Σ to an integral of the "circulation of the fields" (i.e. their curls) over a surface it bounds, i.e. = (), Hence the Ampère–Maxwell law, the modified version of Ampère's circuital law, in integral form can be rewritten as ((+)) =
The Fresnel equations give the ratio of the reflected wave's electric field to the incident wave's electric field, and the ratio of the transmitted wave's electric field to the incident wave's electric field, for each of two components of polarization. (The magnetic fields can also be related using
