      Galerkin formulations of themethod of fundamental solutions 

      Berger, J. R.; Karageorghis, Andreas (2013)
      In this paper,we introduce two Galerkin formulations of the Method of Fundamental Solutions (MFS). In contrast to the collocation formulation of the MFS, the proposed Galerkin formulations involve the evaluation of integrals ...

      GENERAL METHOD OF MINIMUM CROSS-ENTROPY SPECTRAL ESTIMATION. 

      Tzannes, Michael A.; Politis, Dimitris Nicolas; Tzannes, N. S. (1985)
      A new, general approach to estimating power spectra based on minimizing a cross-entropy functional involving spectral densities is presented. Examples are worked out using this approach as well as J. E. Shore's (1979) ...

      GENERAL ROBUST ADAPTIVE LAW FOR TUNING CONTROLLERS. 

      Ioannou, Petros A.; Sun, J. (IEEE, 1986)
      A general robust adaptive law is developed which can stably tune model-reference and pole-placement control schemes despite the presence of unmodeled dynamics and bounded disturbances. The analysis shows that a switching- ...

      A generalization of variance bounds 

      Papadatos, Nickos; Papathanasiou, Vassilis (1996)
      Upper and lower bounds for the variance of a random variable are obtained in terms of the density-quantile function. Some applications of these bounds to order statistics are given.

      A generalized block bootstrap for seasonal time series 

      Dudek, Anna E.; Leśkow, J.; Paparoditis Efstathios, E.; Politis, Dimitris Nicolas (2014)
      When time-series data contain a periodic/seasonal component, the usual block bootstrap procedures are not directly applicable. We propose a modification of the block bootstrap - the generalized seasonal block bootstrap ...

      Generalized divergence measures for survival and reliability data 

      Vonta, Filia; Karagrigoriou, Alex (2012)
      Measures of divergence or discrepancy are used either to measure mutual information concerning two variables or to construct model selection criteria. In this paper we are focusing on divergence measures that are based on ...

      Generalized Lotka - Volterra systems connected with simple Lie algebras 

      Charalambides, Stelios A.; Damianou, Pantelis A.; Evripidou, Charalambos A. (2015)
      We devise a new method for producing Hamiltonian systems by constructing the corresponding Lax pairs. This is achieved by considering a larger subset of the positive roots than the simple roots of the root system of a ...

      Generalized measures of divergence in survival analysis and reliability 

      Vonta, Filia; Karagrigoriou, Alex (2010)
      Measures of divergence or discrepancy are used either to measure mutual information concerning two variables or to construct model selection criteria. In this paper we focus on divergence measures that are based on a class ...

      A generalized randomized response technique 

      Christofides, Tasos C. (2003)
      To eliminate a major source of bias in surveys of human populations resulting from respondents refusal to cooparate in cases where a question of sensitive nature is involved, the idea of "randomized response" was introduced ...

      Generalized seasonal tapered block bootstrap 

      Dudek, Anna E.; Paparoditis Efstathios, E.; Politis, Dimitris Nicolas (2016)
      In this paper a new block bootstrap method for periodic time series called Generalized Seasonal Tapered Block Bootstrap (GSTBB) is introduced. Consistency of the GSTBB for parameters associated with periodically correlated ...

      A generalized-moments specification test for the logistic link 

      Fokianos, Konstantinos; Peng, A.; Qin, J. (1999)
      The authors consider the problem of testing the validity of the logistic regression model using a random sample. Given the values of the response variable, they observe that the sample actually consists of two independent ...

      Genetic algorithms for shortest path routing of autonomous gliders 

      Kahveci, N. E.; Ioannou, Petros A. (2008)
      Onboard power resources pose inevitable limitations on the flight performance of any aerial vehicle regardless of its type, size or mission. Popular soaring techniques recognized to be providing significant energy savings ...

      A gentle (without Chopping) approach to the full Kostant-toda lattice 

      Damianou, Pantelis A.; Magri, F. (2005)
      In this paper we propose a new algorithm for obtaining the rational integrals of the full Kostant-Toda lattice. This new approach is based on a reduction of a bi-Hamiltonian system on gl(n, R). This system was obtained by ...

      A goodness-of-fit test for Poisson count processes 

      Fokianos, Konstantinos; Neumann, M. H. (2013)
      We are studying a novel class of goodness-of-fit tests for parametric count time series regression models. These test statistics are formed by considering smoothed versions of the empirical process of the Pearson residuals. ...

      Goodness-of-fit tests for Markovian time series models: Central limit theory and bootstrap approximations 

      Neumann, M. H.; Paparoditis Efstathios, E. (2008)
      New goodness-of-fit tests for Markovian models in time series analysis are developed which are based on the difference between a fully nonparametric estimate of the one-step transition distribution function of the observed ...
