In this work, we present a bibliography on retrial queues which updates the bibliography published in this journal in Artalejo (1999) [7]. The bibliography is focused on the progress made during the last decade 2000–2009. For the sake of complet[...]texto impreso
We consider an M/G/1 queue with repeated attempts in which the server operates under a general exhaustive service vacation policy. We develop a comprehensive analysis of the system including ergodicity, limiting behaviour, stochastic decompositi[...]texto impreso
In this paper, we model a single-server retrial queue with quasi-random input and two priority classes. In the case of blocking, a high priority unit is queued, whereas a low priority unit joins the orbit to start generating a Poisson flow of re[...]texto impreso
Cathodoluminescence (CL) of the antiferromagnetic oxides NiO and CoO has been investigated. Both compounds show luminescence bands in the visible and near infrared spectral ranges, tentatively attributed to intra-ionic transitions. Dependence of[...]texto impreso
This paper deals with the distribution of the maximum queue length in two-dimensional Markov models. In this framework, two typical assumptions are: (1) the stationary regime, and (2) the system homogeneity (i.e., homogeneity of the underlying i[...]texto impreso
In this paper, we define the concept of C-scattered fuzzy topological spaces and obtain some properties about them. In particular, we study the relation between C-scattered spaces and its fuzzy extension, it is proved that C-scattered fuzzy topo[...]texto impreso
Many of the Currently used cellular networks have been constructed on the premise trial me retrial phenomenon is negligible and the operating environment is static. However. a proper modeling of the mobile cellular network cannot ignore the exis[...]texto impreso
Quaternary interglacials provide key observations of the Earth system's responses to orbital and greenhouse gas forcing. They also inform on the capabilities of Earth system models, used for projecting the polar ice-sheet and sea-level responses[...]texto impreso
The similarity between a magnetic field and a dynamical system is used here to illustrate the idea of integrability, the magnetic surfaces corresponding to the constants of the motion. The transition order-chaos is studied in the case of the sup[...]texto impreso
Second-order Lagrangians depending on a surface which are parameter-invariant and also invariant under rigid motions of Euclidean 3-space are classified.texto impreso
Cruz García, Jesús Manuel de la ; Herrera Caro, Pedro Javier ; Pajares Martinsanz, Gonzalo ; Guijarro Mata-García, María | Pergamon-Elsevier Science Ltd | 2011-07We present a novel strategy for computing disparity maps from omni-directional stereo images obtained with fish-eye lenses in forest environments. At a first segmentation stage, the method identifies textures of interest to be either matched or [...]texto impreso
Fernández Sánchez, Paloma ; Domínguez-Adame Acosta, Francisco ; Piqueras de Noriega, Javier ; Armelles, G. | Pergamon-Elsevier Science Ltd | 1990-10Cathodoluminescence of AlxGa1?xP has been investigated for x between 0.10 and 0.53. A band corresponding to the 610 nm band of pure GaP has been found to shift to higher energies with increasing x. The position of a red band centred at 690 nm is[...]texto impreso
Bartolomé Vílchez, Javier ; Maestre Varea, David ; Cremades Rodríguez, Ana Isabel ; Amatti, M. ; Piqueras de Noriega, Javier | Pergamon-Elsevier Science Ltd | 2013-04Microrods and hierarchical structures of indium-zinc-oxide (IZO) with different compositions were grown by thermal treatments of mixtures of InN and ZnO powders. In long rods, an increase in Zn content along the growth axis is revealed by energy[...]texto impreso
Blasco Contreras, Fernando ; Cuchillo Ibáñez, Eduardo ; Morón, Manuel A. ; Romero López, Carlos | Pergamon-Elsevier Science Ltd | 2000-07In this note, we describe the compromise set for a special polyhedral convex feasible set. This procedure gives the monotonicity of the compromise set. This scenario appears in some engineering and economic applications like the determination of[...]
