  2. Method of characteristics - Wikipedia

    en.wikipedia.org/wiki/Method_of_characteristics

    In mathematics, the method of characteristics is a technique for solving partial differential equations.Typically, it applies to first-order equations, though in general characteristic curves can also be found for hyperbolic and parabolic partial differential equation.

    Ca 5 F(PO 4) 3 + 10 HNO 3 →6 H 3 PO 4 + 5 Ca(NO 3) 2 + HF; 6 HF + SiO 2 →H 2 SiF 6 + 2 H 2 O; Step 2. Removal of Calcium Nitrate. It is important to remove the calcium nitrate because calcium nitrate is extremely hygroscopic. Method 1.(Odda process) Calcium nitrate crystals are removed by centrifugation. Method 2. Sulfonitric Process Ca(NO ...

    x:= 0 y:= 0 x2:= 0 y2:= 0 while (x2 + y2 ≤ 4 and iteration < max_iteration) do y:= 2 * x * y + y0 x:= x2 - y2 + x0 x2:= x * x y2:= y * y iteration:= iteration + 1 Note that in the above pseudocode, 2 x y {\displaystyle 2xy} seems to increase the number of multiplications by 1, but since 2 is the multiplier the code can be optimized via ( x ...

  5. Lagrangian and Eulerian specification of the flow field

    en.wikipedia.org/wiki/Lagrangian_and_Eulerian...

    This is a consequence of the chain rule since we are differentiating the function F(X(x 0, t), t) with respect to t. Conservation laws for a unit mass have a Lagrangian form, which together with mass conservation produce Eulerian conservation; on the contrary, when fluid particles can exchange a quantity (like energy or momentum), only Eulerian ...

  6. Log–log plot - Wikipedia

    en.wikipedia.org/wiki/Log–log_plot

    A log–log plot of y = x (blue), y = x 2 (green), and y = x 3 (red). Note the logarithmic scale markings on each of the axes, and that the log x and log y axes (where the logarithms are 0) are where x and y themselves are 1. Comparison of linear, concave, and convex functions when plotted using a linear scale (left) or a log scale (right).

  7. Plot (graphics) - Wikipedia

    en.wikipedia.org/wiki/Plot_(graphics)

    Drain plot : A two-dimensional plot where the data are presented in a hierarchy with multiple levels. The levels are nested in the sense that the pieces in each pie chart add up to 100%. A waterfall or waterdrop metaphor is used to link each layer to the one below visually conveying the hierarchical structure. Drain Plot. [4]

  8. Domain coloring - Wikipedia

    en.wikipedia.org/wiki/Domain_coloring

    Domain coloring plot of the function f(x) = ⁠ (x 2 − 1)(x − 2 − i) 2 / x 2 + 2 + 2i ⁠, using the structured color function described below. In complex analysis, domain coloring or a color wheel graph is a technique for visualizing complex functions by assigning a color to each point of the complex plane. By assigning points on the ...

  9. Ternary plot - Wikipedia

    en.wikipedia.org/wiki/Ternary_plot

    10%: 60%: 30%: The proportion of sand is 30% as in Sample 1, but as the proportion of silt rises by 40%, the proportion of clay decreases correspondingly. Sample 3: 10%: 30%: 60%: This sample has the same proportion of clay as Sample 2, but the proportions of silt and sand are swapped; the plot is reflected about its vertical axis.
