Higher-order mechanics: variational principles and other topics
(American Institute of Mathematical Sciences, 2013-12)
Article
Accés obertAfter reviewing the Lagrangian-Hamiltonian unified formalism (i.e, the Skinner-Rusk formalism) for higher-order (non-autonomous) dynamical systems, we state a unified geometrical version of the Variational Principles which ... -
Geometric Hamilton-Jacobi theory for higher-order autonomous systems
(2013-09-09)
Report de recerca
Accés obertThe geometric framework for the Hamilton-Jacobi theory is used to study this theory in the ambient of higher-order mechanical systems, both in the Lagrangian and Hamiltonian formalisms. Thus, we state the corresponding ... -
Unified formalism for the generalized kth-order Hamilton-Jacobi problem
(2013-10-03)
Report de recerca
Accés obertThe geometric formulation of the Hamilton-Jacobi theory enables u s to generalize it to systems of higher-order ordinary differential equations. In this w ork we introduce the unified Lagrangian-Hamiltonian formalism ... -
Reduction of polysymplectic manifolds
(2013-06-06)
Report de recerca
Accés obertThe aim of this paper is to generalize the classical Marsden- Weinstein reduction procedure for symplectic manifolds to polysymplectic manifolds in or der to obtain quotient manifolds which in- herit the polysymplectic ... -
Kinematic reduction and the Hamilton-Jacobi equation
(American Institute of Mathematical Sciences, 2012)
Article
Accés obertA close relationship between the classical Hamilton- Jacobi theory and the kinematic reduction of control systems by decoupling vector fields is shown in this paper. The geometric interpretation of this relationship ... -
Characterization of accessibility for affine connection control systems at some points with nonzero velocity
(2011)
Comunicació de congrés
Accés restringit per política de l'editorialAffine connection control systems are mechanical control systems that model a wide range of real systems such as robotic legs, hovercrafts, planar rigid bodies, rolling pennies, snakeboards and so on. In 1997 the accessibility ... -
Higher education needs for the information and communication technology spanish market
(2011-10)
Article
Accés obertPurpose: The main objective of the paper is to clarify the expectations held in the realm of business and by employers, in relation to the main educational parameters that respond to the employment needs of the Information ... -
On a kind of Noether symmetries and conservation laws in k-cosymplectic field theory
(2011-02)
Article
Accés obertThis paper is devoted to studying symmetries of certain kinds of k-cosymplectic Hamiltonian systems in first-order classical field theories. Thus, we introduce a particular class of symmetries and study the problem of ... -
On the k-symplectic, k-cosymplectic and multisymplectic formalisms of classical field theories
(American Institute of Mathematical Sciences, 2011-03)
Article
Accés restringit per política de l'editorialThe objective of this work is twofold: First, we analyze the relation between the k-cosymplectic and the k-symplectic Hamiltonian and Lagrangian formalisms in classical eld theories. In particular, we prove the equivalence ... -
Lagrangian-Hamiltonian unified formalism for autonomous higher order dynamical systems
(2011-09-23)
Article
Accés restringit per acord de confidencialitatThe Lagrangian-Hamiltonian unified formalism of R. Skinner and R. Rusk was originally stated for autonomous dynamical systems in classical mechanics. It has been generalized for non-autonomous first-order mechanical ... -

The ICT skills gap in Spain: industry expectations versus university preparation
(2010-06-29)
Article
Accés restringit per política de l'editorialThis article distinguishes which generic skills are the key to enable newly graduated engineers, basically computer and telecommunication engineers, to enter the information and communication technology (ICT) sector, ...
