- Orcid: 0000-0002-1049-9752
I am an applied mathematician, and I work in mathematical methods for advance manufacturing under the umbrella of the Artificial Intelligent Manufacturing and Sustainability (AIMS) unit. I collaborate with engineers at the Aeronautics Advanced Manufacturing Center (CFAA, spanish acronym) in Zamudio.
I am interested in monitoring of metal cutting processes, which entails understanding the dynamics of metal cutting and modelling of machine elements performance. To a lower degree I am interested in FEM simulations.

Semi-Analytical Estimation for the Escape of Solutions of Linear Differential Equations with Slowly Varying Coefficients
Ponce Vanegas, F.
; Bartfai, A.; Dombovari, Z. (2024)
Emerging vibrations are a major and often unpredictable limitation in engineering design. The engineering description of these vibrations is usually based on linear models with constant parameters. However, in reality, ...

Semi-analytical framework for the study of finite-time stability of forced dynamical systems with time varying parameters
Bartfai, A.; Ponce Vanegas, F.; Hogan, J.; Kuske, R.; Dombovari, Z. (2024)
We present a framework to analytically approximate the solution of forced dynamical systems with time varying parameters and to analyse their finite-time stability. The work was inspired by an example in robotic machining, ...

The Tustin Method for approximating eigenvalues of delay systems
Irastorza, M.; Ponce Vanegas, F. (2024)
Numerical approximation of the eigenvalues of Delay Differential Equations (DDEs) is an active field of research due to its impact in the modelling of several processes of industrial interest. In this work we introduce the ...

On C0 and C1 continuity of envelopes of rotational solids and its application to 5-axis CNC machining
Ponce Vanegas, F.; Bizzarri, M.; Barton, M. (2023-10)
We study the smoothness of envelopes generated by motions of rotational rigid bodies in the context of 5-axis Computer Numerically Controlled (CNC) machining. A moving cutting tool, conceptualized as a rotational solid, ...

The Frisch–Parisi formalism for fluctuations of the Schrödinger equation
Kumar, S.; Ponce Vanegas, F.; Roncal, L.; Vega, L. (2022)
We consider the solution of the Schrödinger equation $u$ in $\mathbb{R}$ when the initial datum tends to the Dirac comb. Let $h_{\text{p}, \delta}(t)$ be the fluctuations in time of $\int\lvert x \rvert^{2\delta}\lvert ...

Counterexamples for the fractal Schrödinger convergence problem with an Intermediate Space Trick
Eceizabarrena, D.; Ponce Vanegas, F. (2021-12-09)
We construct counterexamples for the fractal Schrödinger convergence problem by combining a fractal extension of Bourgain's counterexample and the intermediate space trick of Du--Kim--Wang--Zhang. We confirm that the same ...

Pointwise Convergence over Fractals for Dispersive Equations with Homogeneous Symbol
Eceizabarrena, D.; Ponce Vanegas, F. (2021-08-24)
We study the problem of pointwise convergence for equations of the type $i\hbar\partial_tu + P(D)u = 0$, where the symbol $P$ is real, homogeneous and non-singular. We prove that for initial data $f\in H^s(\mathbb{R}^n)$ ...

Static and Dynamical, Fractional Uncertainty Principles
Kumar, S.; Ponce Vanegas, F.; Vega, L. (2021-03)
We study the process of dispersion of low-regularity solutions to the Schrödinger equation using fractional weights (observables). We give another proof of the uncertainty principle for fractional weights and use it to get ...

Convergence over fractals for the Schrödinger equation
Lucà, R.; Ponce Vanegas, F. (2021-01)
We consider a fractal refinement of the Carleson problem for the Schrödinger equation, that is to identify the minimal regularity needed by the solutions to converge pointwise to their initial data almost everywhere with ...

A Bilinear Strategy for Calderón’s Problem
Ponce Vanegas, F. (2020-05)
Electrical Impedance Imaging would suffer a serious obstruction if two different conductivities yielded the same measurements of potential and current at the boundary. The Calderón’s problem is to decide whether the ...

Reconstruction of the Derivative of the Conductivity at the Boundary
Ponce Vanegas, F. (2019-08)
We describe a method to reconstruct the conductivity and its normal derivative at the boundary from the knowledge of the potential and current measured at the boundary. This boundary determination implies the uniqueness ...

A Bilinear Strategy for Calderón's Problem
Ponce Vanegas, F. (2019-08)
Electrical Impedance Imaging would suffer a serious obstruction if for two different conductivities the potential and current measured at the boundary were the same. The Calder\'on's problem is to decide whether the ...
