Applications of Visibility Graphs for the representation of Time Series

Mira Iglesias, Ainara (Universitat Politècnica de València, 2021-11-04)

[EN] In this thesis, we consider two problems: we first explore the application of visibility graphs for describing the orbits of a discrete dynamical system that is governed by a fractional version of the logistic equation. ...
Chaos for dynamics of birth-and-death models

Aroza Benlloch, Javier (Universitat Politècnica de València, 2011-09-28)

Characterization of the complexity in short oscillating time series: An application to seismic airgun detonations

Miralles Ricós, Ramón; Carrión García, Alicia; Looney, D.; Lara Martínez, Guillermo-Fernán; D. Mandic (Acoustical Society of America, 2015-09)

Extracting frequency-derived parameters allows for the identification and characterization of acoustic events, such as those obtained in passive acoustic monitoring applications. Situations where it is difficult to achieve ...
Complex dynamics of defective interfering baculoviruses during serial passage in insect cells

Zwart, Mark Peter; Pijlman, G.P.; Sardanyes Cayuela, Jose; Duarte, J; Januario, C; Elena Fito, Santiago Fco (Springer Verlag (Germany), 2013-03)

Defective interfering (DI) viruses are thought to cause oscillations in virus levels, known as the 'Von Magnus effect'. Interference by DI viruses has been proposed to underlie these dynamics, although experimental tests ...
CONTRAPUNTO arquitectónico en las manzanas enfrentadas de Morvedre.

Aguado Vicaria, Susana (Universitat Politècnica de València, 2022-09-05)

[ES] La calle Sagunto. Una calle que demanda ser cursora de un gran flujo de individuos y de actividad, se encuentra coronada por dos manzanas con vocación de identidad. Éstas, inmersas en una trama desordenada y arraigadas ...
Controlled shadowing property

Zamani Bahabadi, Alireza (Universitat Politècnica de València, 2018-04-02)

[EN] In this paper we introduce a new notion, named controlled shadowing property and we relate it to some notions in dynamical systems such as topological ergodicity, topologically mixing and specication properties. The ...
Dynamical analysis of an iterative method with memory on a family of third-degree polynomials

Campos, Beatriz; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Vindel, Pura (American Institute of Mathematical Sciences, 2022)

[EN] Qualitative analysis of iterative methods with memory has been carried out a few years ago. Most of the papers published in this context analyze the behaviour of schemes on quadratic polynomials. In this paper, we ...
Dynamics of strongly continuous semigroups associated to certain differential equations

Aroza Benlloch, Javier (Universitat Politècnica de València, 2015-11-09)

[EN] The purpose of the Ph.D. Thesis "Dynamics of strongly continuous semigroups associated to certain differential equations'' is to analyse, from the point of view of functional analysis, the dynamics of solutions of ...
El caos en los métodos iterativos de resolución de ecuaciones no lineales

Moscoso Martínez, Marlon Ernesto (Universitat Politècnica de València, 2020-09-02)

[ES] En el presente trabajo se estudia la dinámica compleja de una familia de métodos con esquemas iterativos multipaso, que es una generalización de un método propuesto por Artidiello y col., sobre polinomios cuadráticos. ...
Existence of an optimum dynamic coefficient of friction and the influence on human gait variability

Zamora Alvarez, Tomas Augusto; Alcantara Alcover, Enrique; Artacho Ramírez, Miguel Ángel; Valero Martínez, Marta (Elsevier, 2011-09)

The existence of a range of optimal coefficient of friction that encompasses safety and comfort has not been addressed before. This paper assesses the existence of such a range and its relationship with the variability of ...
