Multivariate feature ranking of gene expression data
Fernando Jiménez, Gracia Sánchez, José Palma +2
Gene expression datasets are usually of high dimensionality and therefore require efficient and effective methods for identifying the relative importance of their attributes. Due t…
A novel auction system for selecting advertisements in Real-Time bidding
Luis Miralles-Pechuán, Fernando Jiménez, José Manuel García
Real-Time Bidding is a new Internet advertising system that has become very popular in recent years. This system works like a global auction where advertisers bid to display their…
A Deep Q-learning/genetic Algorithms Based Novel Methodology For Optimizing Covid-19 Pandemic Government Actions
Luis Miralles-Pechuán, Fernando Jiménez, Hiram Ponce +1
Whenever countries are threatened by a pandemic, as is the case with the COVID-19 virus, governments should take the right actions to safeguard public health as well as to mitigate…
Continuous and discrete damping reduction for systems with quadratic interaction
Farhang Haddad Farshi, Fernando Jiménez, Sina Ober-Blöbaum
We study the connection between Lagrangian and Hamiltonian descriptions of closed/open dynamics, for a collection of particles with quadratic interaction (closed system) and a sub-…
A Fractional Variational Approach for Modelling Dissipative Mechanical Systems: Continuous and Discrete Settings
Fernando Jiménez, Sina Ober-Blöbaum
Employing a phase space which includes the (Riemann-Liouville) fractional derivative of curves evolving on real space, we develop a restricted variational principle for Lagrangian…
Classical and quantum-linearized descriptions of degenerate optomechanical parametric oscillators
Sebastian Pina-Otey, Fernando Jiménez, Peter Degenfeld-Schonburg +1
Recent advances in the development of modern quantum technologies have opened the possibility of studying the interplay between spontaneous parametric down-conversion and optomecha…
Dirac Structures in Vakonomic Mechanics
Fernando Jiménez, Hiroaki Yoshimura
In this paper, we explore dynamics of the nonholonomic system called vakonomic mechanics in the context of Lagrange-Dirac dynamical systems using a Dirac structure and its associat…
New developments on the Geometric Nonholonomic Integrator
Sebastián Ferraro, Fernando Jiménez, David Martín de Diego
In this paper, we will discuss new developments regarding the Geometric Nonholonomic Integrator (GNI) [23, 24]. GNI is a discretization scheme adapted to nonholonomic mechanical sy…
Variational integrators for underactuated mechanical control systems with symmetries
Leonardo Colombo, Fernando Jiménez, David Martín de Diego
Optimal control problems for underactuated mechanical systems can be seen as a higher-order variational problem subject to higher-order constraints (that is, when the Lagrangian fu…
Fokker-Planck approach to quantum lattice Hamiltonians
Fernando Jiménez, Germán Sierra
Fokker-Planck equations have been applied in the past to field theory topics such as the stochastic quantization and the stabilization of bottomless action theories. In this paper…
