A sliding mode approach to robust stabilisation of Markovian jump linear time-delay systems with generally incomplete transition rates
2015
Abstract This paper is devoted to investigating the problem of robust sliding mode control for a class of uncertain Markovian jump linear time-delay systems with generally uncertain transition rates (GUTRs). In this GUTR model, each transition rate can be completely unknown or only its estimate value is known. By making use of linear matrix inequalities technique, sufficient conditions are presented to derive the linear switching surface and guarantee the stochastic stability of sliding mode dynamics. A sliding mode control law is developed to drive the state trajectory of the closed-loop system to the specified linear switching surface in a finite-time interval in spite of the existing unc…
Symbolic Reductionist Model for Program Comprehension
2007
This article presents the main features of a novel construction, symbolic analysis, for automatic source code processing. The method is superior to the known methods, because it uses a semiotic, interpretative approach. Its most important processes and characteristics are considered here. We describe symbolic information retrieval and the process of analysis in which it can be used in order to obtain pragmatic information. This, in turn, is useful in understanding a current Java program version when developing a new version.
Passive time-multiplexing super-resolved technique for axially moving targets
2013
In this paper we present a super-resolving approach for detecting an axially moving target that is based upon a time-multiplexing concept and that overcomes the diffraction limit set by the optics of an imaging camera by a priori knowledge of the high-resolution background in front of which the target is moving. As the movement trajectory is axial, the approach can be applied to targets that are approaching or moving away from the camera. By recording a set of low-resolution images at different target axial positions, the super-resolving algorithm weights each image by demultiplexing them using the high-resolution background image and provides a super-resolved image of the target. Theoretic…
Trajectory of Affordances: Insights from a case of telemedicine in Nepal
2017
Although Affordance Theory has become increasingly influential in the Information Systems (IS) literature, the exact process through which the affordances of IT are actualised is less studied. In t ...
The link between vulnerability and social exclusion and criminal trajectories. An association study
2017
Este estudio tiene por objeto identificar la relación existente entre las trayectorias delictivas y los factores de vulnerabilidad y exclusión social en adolescentes en conflicto con la ley. Para ello se analizan 281 expedientes de adolescentes en conflicto con la ley de la ciudad de València y se generan 3 trayectorias delictivas: inicial, moderada y consolidada, que se asocian a indicadores de vulnerabilidad y exclusión social. Se muestran evidencias empíricas de su relación. Las trayectorias delictivas y los factores de vulnerabilidad y exclusión social se hallan plenamente conectados, entrelazados y superpuestos. La acumulación de factores de vulnerabilidad y exclusión social en adolesc…
Sortants du supérieur : le niveau de diplôme ne résume pas les trajectoires d'insertion
2022
Le début de carrière des jeunes sortis de l’enseignement supérieur en 2017 ne déroge pas à la règle : il est d'autant plus favorable que leur niveau d’études est élevé. Il varie néanmoins selon la spécificité de chaque diplôme, celle de la formation suivie et les caractéristiques des publics concernés. Pour la Génération 2017, les débuts dans la vie active se heurtent également au premier confinement, dont les effets varient alors davantage en fonction des segments d'emploi que du niveau de diplôme.
Ce que l'indicateur NEET ne dit pas sur la fracture sociale de la jeunesse
2022
En début de vie active, nombreux sont les jeunes à passer par la catégorie des NEET. La durée de l'épisode dépend, au-delà du diplôme, des caractéristiques individuelles. Celles et ceux qui peinent à s'en extraire forment une population vulnérable que les politiques publiques tentent d'atteindre.
A first return examination of vector valued integrals.
2009
We prove that for each Bochner integrable function f there exists a trajectory yielding the Bochner integral of f, and that on infinite dimensional Banach spaces there exist Pettis integrable functions f such that no trajectory yields the Pettis integral of f.
El traje popular en el siglo XVII
2009
El objetivo de este artículo es estudiar las formas de vertido de los hombres y mujeres que formaban parte del estamento popular o tercer estado de la sociedad del Antiguo Régimen y que habitaron el antiguo Reino de Aragón durante el siglo XVII. Para llevar a cabo este trabajo he tomado ejemplos extraídos del Archivo Histórico de Protocolos Notariales de la ciudad de Alcañiz. Población que por sus características puede ser tomada como ejemplo y reflejo de cualquier ciudad aragonesa del siglo XVII. (A)
Hypothesis testing for Panels of Semi-Markov Processes with parametric sojourn time distributions
2022
This work deals with the asymptotic properties of maximum likelihood estimators for semi-Markov processes with parametric sojourn time distributions. It is motivated by the comparison, via a two-sample test procedure, of the distribution of two panels of qualitative trajectories modeled by semi-Markov processes and observed over a random number of transitions. Considering first one panel of growing size, we derive, under classical conditions, the convergence in probability of the estimators of the transition probabilities and the parameters of the sojourn time distributions as well as their asymptotic normality. We then consider panels of semi-Markov processes drawn from two different popul…
