In this work, the Finite Element Method is used for finding the numerical solution of an elliptic problem with Henstock–Kurzweil integrable functions. In particular, Henstock–Kurzweil high oscillatory functions were considered. The weak formulati

In this paper, we give sufficient conditions for the existence and uniqueness of the solution of Sturm–Liouville equations subject to Dirichlet boundary value conditions and involving Kurzweil–Henstock integrable functions on unbounded intervals.

We prove that the controlled continuity, induced by controlled convergence, and continuity in norm are equivalent for linear operators defined on the space of Henstock integrable vector-valued functions.

In this paper, we introduce the HK-Sobolev space and establish a fundamental theorem of calculus and an integration by parts formula, then we give sufficient conditions for the existence and uniqueness of a solution to a variational problem associate

We segment the images of particles moving in optical traps to recover their irradiance and deformation. We use Legendre polynomials to correct the deformation and retrieve the phase using the 3D profile of the particle.

We obtain 3D profiles of objects in optical traps from image segmentation, giving place to an irradiance distribution. We recover the phase using 2D Legendre poly- nomials (2D-LP) and compare our technique with the Gerchberg-Saxton method.

We introduce a technique for obtaining three-dimensional (3D) profiles of objects captured in two-dimensional (2D) flat images (FI). This technique performs a numerical approximation of the object’s topography from their image gray tones, analyzing

The Irradiance Transport Equation is considered as an elliptical differential equation that determines the phase as a poorly stated problem. The instability of such a problem is handled as Tikhonov regularization method to determine aberrations.

We are focused on the phase retrieval and 3D profiles of microparticles (MP), analyzed in optical trapping. To this aim, we use several image segmentation procedures of MP from an optical trapping video. Moreover, we implement different procedures to
