Electroosmotic flow profile distortion due to Laplace pressures at the end reservoirs
(Springer Heidelberg, 2016-01)
The build-up of pressure-driven backflows is a known drawback to electroosmotic plug flow. We have studied the characteristic time constant of these pressure gradients build-up as a function of various geometrical variables ...
Approximated analytical solution to an Ebola optimal control problem
(Board Members, 2016-01-01)
An analytical expression for the optimal control of an Ebola problem is obtained. The analytical solution is found as a first-order approximation to the Pontryagin Maximum Principle via the Euler-Lagrange equation. An ...

The objective of this work is to use differential equation methods to solve circuits with a high degree of complexity, in a didactic and understandable way. In this way, mathematical tools such as Laplace transforms will ...
Symmetry results in the half-space for a semi-linear fractional Laplace equation
(2018)
In this paper, we analyze the semi-linear fractional Laplace equation (-Delta)(s) u = f (u) in R-+(N), u = 0 in R-N \R-+(N), where R-+(N) = {x = (x', x(N)) is an element of R-N : x(N) > 0) stands for the half-space and f ...
