  • [PEER Project Non-TCD]On open problems in polling systems 

    Boon, Marko; Boxma, Onno J.; Winands, Erik M. M. (Springer USBostonhttp://www.springer-ny.com, 2011-07-09)
    Abstract In the present paper we address two open problems concerning polling systems, viz., queueing systems consisting of multiple queues attended by a single server that visits the queues one at a time. The first ...
  • [PEER Project Non-TCD]Tail behaviour of the area under a random process, with applications to queueing systems, insurance and percolations

    Abstract The areas under the workload process and under the queueing process in a single-server queue over the busy period have many applications not only in queueing theory but also in risk theory or percolation ...

    Abstract Hail is more hazardous for aircraft engines compared to rain and snow,mainly, because of its solid nature and high water content. In extreme cases it can lead to engine ame out. In order to avoid such ...
  • [PEER Project Non-TCD]Hard Projectile Penetration and Trajectory Stability 

    Li, Q.M.; Flores-Johnson, E.A. (Elsevier, 2011-07-08)
    Abstract We present a general framework to describe the dynamics of a hard projectile penetrating into a solid target. Rigid-body dynamics, differential area force law and semi-empirical resistance function are ...
  • [PEER Project Non-TCD]On the greedy walk problem 

    Bordenave, Charles; Foss, Sergey; Last, Gunter (Springer USBostonhttp://www.springer-ny.com, 2011-07-06)
    Abstract This note introduces a greedy walk on Poisson and Binomial processes, which is a close relative to the well-known greedy server model. Some open problems are presented.
  • [PEER Project Non-TCD]Open problems in Gaussian fluid queueing theory 

    De?bicki, K.; Mandjes, M. (Springer USBostonhttp://www.springer-ny.com, 2011-07-06)
    Abstract We present three challenging open problems that originate from the analysis of the asymptotic behavior of Gaussian fluid queueing models. In particular, we address the problem of characterizing the correlation ...
  • [PEER Project Non-TCD]Price Variation Antagonism and Firm Pricing Policies 

    Courty, Pascal; Pagliero, Mario (Elsevier, 2010-07-02)
    Abstract Pricing schemes that vary prices in response to demand shocks may antagonize consumers and reduce demand. At the same time, consumers may take advantage of the opportunities offered by price changes. ...
  • [PEER Project Non-TCD]Tandem queueing networks with neighbor blocking and back-offs 

    Borst, Sem C.; Hellings, Ton; Leeuwaarden, Johan S. H. (Springer USBostonhttp://www.springer-ny.com, 2011-07-01)
    Abstract We introduce a novel class of tandem queueing networks which arise in modeling the congestion behavior of wireless multi-hop networks with distributed medium access control. These models provide valuable ...
  • [PEER Project Non-TCD]Symplectic regularization of binary collisions in the circular N+2 Sitnikov problem 

    Jimenez-Perez, Hugo; Lacomba, Ernesto A (IOP Publishing, 2011-07-01)
    Abstract We present a brief overview of the regularizing transformations of the Kepler problem and we relate the Euler transformation with the symplectic structure of the phase space of the N -body problem. We show that ...
  • [PEER Project Non-TCD]An I(d) model with trend and cycles 

    Abadir, Karim M.; Distaso, Walter; Giraitis, Liudas (Elsevier, 2011-06-15)
    Abstract This paper deals with models allowing for trending processes and cyclical component with error processes that are possibly nonstationary, nonlinear, and non-Gaussian. Asymptotic confidence intervals for ...
  • [PEER Project Non-TCD]A class of simple distribution-free rank-based unit root tests 

    Hallin, Marc; van den Akker, Ramon; Werker, Bas J.M. (Elsevier, 2011-06-15)
    Abstract We propose a class of distribution-free rank-based tests for the null hypothesis of a unit root. This class is indexed by the choice of a reference density g, which needs not coincide with the unknown ...
  • [PEER Project Non-TCD]Likelihood-based scoring rules for comparing density forecasts in tails 

    van Dijk, Dick; Diks, Cees; Panchenko, Valentyn (Elsevier, 2011-06-15)
    Abstract We propose new scoring rules based on conditional and censored likelihood for assessing the predictive accuracy of competing density forecasts over a specific region of interest, such as the left tail in ...
  • [PEER Project Non-TCD]Numerical predictions of the behaviour of soft clay with two anisotropic elastoplastic models 

    Venda Oliveira, Paulo J.; Lemos, Luis J.L. (Elsevier, 2011-06-03)
    Abstract The numerical predictions obtained with the Melanie and MIT-E3 models are compared. Firstly, the performance of the constitutive models is checked against undrained triaxial tests. The models are then used ...
  • [PEER Project Non-TCD]Numerical Simulation Of Impact Tests On Gfrp Composite Laminates 

    menna, Costantino; asprone, Domenico; caprino, Giancarlo; lopresto, Valentina; prota, Andrea (Elsevier, 2011-06-02)
    Abstract The design of advanced composite structures or components subjected to dynamic loadings requires a deep understanding of the damage and degradation mechanisms occurring within the composite material. The ...
  • [PEER Project Non-TCD]A Numerical Study of the Behaviour and Failure Modes of Axially Compressed Steel Columns Subjected to Transverse Impact 

    Wang, Y.C.; AL Thairy, H. (Elsevier, 2011-06-02)
    Abstract In this study a numerical simulation of the behaviour and failure modes of axially compressed steel column subjected to transverse impact by a rigid mass at different impact speeds and locations is presented. ...
  • [PEER Project Non-TCD]Search in the product market and the real business cycle 

    Pierrard, Olivier; Matha, Thomas (Elsevier, 2011-06-01)
    Abstract Abstract Empirical evidence suggests that most firms operate in imperfectly competitive markets. We develop a search-matching model between wholesalers and retailers. Firms face search costs and ...
  • [PEER Project Non-TCD]Adaptive expectations and cobweb phenomena: does heterogeneity matter? 

    Valori, Vincenzo; Colucci, Domenico (Elsevier, 2011-06-01)
    Abstract Abstract This paper studies a cobweb-type commodity market characterised by a strictly monotone demand and supply, in which (n) types of firms operate. Types differ in a key parameter governing ...
  • [PEER Project Non-TCD]Maximum likelihood estimation for dynamic factor models with missing data 

    Koopman, S.J.; Jungbacker, B.; van der Wel, M. (Elsevier, 2011-06-01)
    Abstract This paper concerns estimating parameters in a high-dimensional dynamic factor model by the method of maximum likelihood. To accommodate missing data in the analysis, we propose a new model representation ...
