Average value of the DC-link output voltage in multi-phase uncontrolled bridge rectifiers under supply voltage balance and unbalance conditions
(2021-12-01)
Article
Restricted access - publisher's policyAverage value of the DC-link output voltage is a variable of interest in multi-phase uncontrolled bridge rectifiers. The aim of this paper is to present a new, effort-saving procedure capable of providing an accurate value ... -
Geometrically polarized architected dielectrics with apparent piezoelectricity
(2021-12)
Article
Open AccessThrough the suitable geometry of a repeating unit, a metamaterial can exhibit a property not present in the base material. Here, we propose a class of low area-fraction, bending-dominated metamaterials that exhibit apparent ... -
The force loading rate drives cell mechanosensing through both reinforcement and cytoskeletal softening
(2021-07-09)
Article
Open AccessCell response to force regulates essential processes in health and disease. However, the fundamental mechanical variables that cells sense and respond to remain unclear. Here we show that the rate of force application ... -
Geometric quantization via cotangent models
(2021-09)
Article
Open AccessIn this article we give a universal model for geometric quantization associated to a real polarization given by an integrable system with non-degenerate singularities. This universal model goes one step further than the ... -
On the enumeration of bipartite simple games
(2021-07-15)
Article
Restricted access - publisher's policyThis paper provides a classification of all monotonic bipartite simple games. The problem we deal with is very versatile since simple games are inequivalent monotonic Boolean functions, functions that are used in many ... -
Global phase-amplitude description of oscillatory dynamics via the parameterization method
(Institute of Physics (IOP), 2020-08-01)
Article
Open AccessIn this paper, we use the parameterization method to provide a complete description of the dynamics of an n-dimensional oscillator beyond the classical phase reduction. The parameterization method allows us, via efficient ... -
Analytical and numerical results on families of n-ejection-collision orbits in the RTBP
(2020-11-01)
Article
Restricted access - publisher's policyIn the planar RTBP with mass ratio µ we regularise the singularity at one of the primaries by means of Levi-Civita’s transformation in a rotating frame. We solve the variational equations in a neighbourhood of the ... -
Identifying codes in line digraphs
(Elsevier, 2020-10-15)
Article
Restricted access - publisher's policyGiven an integer ` = 1, a (1, = `)-identifying code in a digraph is a dominating subset C of vertices such that all distinct subsets of vertices of cardinality at most ` have distinct closed in-neighbourhood within C. In ... -
Optimal regularity of stable solutions to nonlinear equations involving the p-Laplacian
(2020-01-01)
Article
Open AccessWe consider the equation-¿pu=f(u)in a smooth bounded domain ofRn, where¿pis thep-Laplaceoperator. Explicit examples of unbounded stable energy solutions are known ifn=p+4pp-1. Instead, whenn<p+4pp-1, stable solutions have ... -
A contact geometry framework for field theories with dissipation
(2020-03-01)
Article
Open AccessWe develop a new geometric framework suitable for dealing with Hamiltonian field theories with dissipation. To this end we define the notions of k-contact structure and k-contact Hamiltonian system. This is a generalization ... -
Structure and enumeration of K4-minor-free links and link-diagrams
(2020-10-01)
Article
Open AccessWe study the class of link-types that admit a -minor-free diagram, i.e., they can be projected on the plane so that the resulting graph does not contain any subdivision of . We prove that is the closure of a subclass of ... -
Unified Lagrangian-Hamiltonian formalism for contact systems
(2020-06-23)
Article
Open AccessWe present a unified geometric framework for describing both the Lagrangian and Hamiltonian formalisms of contact autonomous mechanical systems, which is based on the approach of the pioneering work of R. Skinner and R. ...
