<p>We propose a new design scheme of resilient Wavelength Division Multiplexing (WDM) networks by extending and reshaping pre-configured protection tree (<i...

We consider a marketing channel with a single manufacturer and a single retailer, where both advertising and quality improvement contribute to the build-up o...

In this paper we extend some results in Cramér (1955) by considering the expected discounted penalty function as a generalization of the infinite time ruin p...

A discretization scheme for nonnegative diffusion processes is proposed and the convergence of the corresponding sequence of approximate processes is proved ...

This paper aims at developing omnibus procedures for testing for serial correlation using spectral density estimation and wavelet shrinkage. We derive the as...

We address the problem of locating in the plane objects such as segments, arcs of circumferences, arbitrary convex sets, their complements or their boundarie...

Harmonic means clustering is a variant of Minimum sum of squares clustering (which is sometimes called <i>K</i>-means clustering), designed to alleviate the ...

Variable neighborhood search (VNS) is a metaheuristic for solving combinatorial and global optimization problems whose basic idea is a systematic change o...

Let <i>Q = D + A</i> denote the signless Laplacian matrix of a graph <i>G</i> of order <i>n</i>, where <i>D</i> is the diagonal matrix of the degrees and <i...

The <i>Vehicle routing Problem</i> (VRP) was introduced 50 years ago by Dantzig and Ramser under the title "The Truck Dispatching Problem". The study of the ...

This paper deals with the design and dimensioning of a novel survivable optical network structure, called Petaweb, that can reach a total capacity of severa...

The paper provides a survey of the literature which utilizes dynamic state-space games to formulate and analyze intertemporal, many-decision maker problems i...

Given a set of scheduled flights that must be operated by the same aircraft type, the aircraft routing problem (ARP) consists of building anonymous aircraft ...

Many time series encountered in real applications display seasonal behavior. In this paper, we consider multiplicative seasonal vectorial autoregressive movi...

Given a graph <i>G=(V,E)</i>, the first Zagreb index <i>M</i>₁ is the sum of its vertices squared degrees and the second Zagreb index <i>M</i><sub...

We consider in this paper a duopoly competing in quantities and where firms can invest in R&D to control their emissions. We distinguish between effort carri...

This paper presents an efficient approach for realistic modelling of internal transport systems. The weakness of the former methods in tracking the traffic w...

This paper presents a new generic architecture for the implementation of an intelligent simulation-based real-time control in large-scale discrete-events sys...

Khalifeh, Yousefi-Azari, Ashrafi and Wagner [European J. Combin. 30 (2009) 1149-1163] conjectured that for a connected graph <i>G</i> on <i>n</i> vertices...

<p>Today, OCS (Optical Circuit Switching) is still the only mature technology for optical transfer, even if it suffers from its coarse granularity under dyn...
