  2. Gouy–Stodola theorem - Wikipedia

    en.wikipedia.org/wiki/Gouy–Stodola_theorem

    The theorem is also useful on a more microscopic scale, in biology. Living systems, such as cells, can be analyzed thermodynamically. They are rather complex systems, where many energy transformations occur, and they often waste heat. Hence, the Gouy-Stodola theorem may be useful, in certain situations, to perform exergy analysis on such systems.

  3. Poisson–Boltzmann equation - Wikipedia

    en.wikipedia.org/wiki/Poisson–Boltzmann_equation

    The Poisson–Boltzmann equation describes a model proposed independently by Louis Georges Gouy and David Leonard Chapman in 1910 and 1913, respectively. [3] In the Gouy-Chapman model, a charged solid comes into contact with an ionic solution, creating a layer of surface charges and counter-ions or double layer. [4]

  4. Littlewood's three principles of real analysis - Wikipedia

    en.wikipedia.org/wiki/Littlewood's_three...

    Littlewood's three principles are quoted in several real analysis texts, for example Royden, [2] Bressoud, [3] and Stein & Shakarchi. [4] Royden [5] gives the bounded convergence theorem as an application of the third principle. The theorem states that if a uniformly bounded sequence of functions converges pointwise, then their integrals on a ...

    Following the classical finite volume method framework, we seek to track a finite set of discrete unknowns, = / + / (,) where the / = + (/) and = form a discrete set of points for the hyperbolic problem: + (()) =, where the indices and indicate the derivatives in time and space, respectively.

    Louis Georges Gouy. Louis Georges Gouy (February 19, 1854 – January 27, 1926) [1] was a French physicist.He is the namesake of the Gouy balance, the Gouy–Chapman electric double layer model (which is a relatively successful albeit limited model that describes the electrical double-layer which finds applications in vast areas of studies from physical chemistry to biophysics) and the Gouy phase.

    See for example Riemann–Lebesgue lemma. The second statement is that when f is a Morse function, so that the singular points of f are non-degenerate and isolated, then the question can be reduced to the case n = 1. In fact, then, a choice of g can be made to split the integral into cases with just one critical point P in each.

  8. Variational inequality - Wikipedia

    en.wikipedia.org/wiki/Variational_inequality

    Following Antman (1983, p. 283), the definition of a variational inequality is the following one.. Given a Banach space, a subset of , and a functional : from to the dual space of the space , the variational inequality problem is the problem of solving for the variable belonging to the following inequality:

  9. Homotopy principle - Wikipedia

    As another simple example, consider a car moving in the plane. The position of a car in the plane is determined by three parameters: two coordinates x {\displaystyle x} and y {\displaystyle y} for the location (a good choice is the location of the midpoint between the back wheels) and an angle α {\displaystyle \alpha } which describes the ...
