Identifiability of mixtures of power-series distributions and related characterizations
(1995)The concept of the identifiability of mixtures of distributions is discussed and a sufficient condition for the identifiability of the mixture of a large class of discrete distributions, namely that of the power-series ...

Identification and control of aircraft dynamics using radial basis function networks
(Publ by IEEE, 1993)In this paper, we investigate one type of neural networks, namely the Radial Basis Functions (RBF) networks, and apply them to the identification and control problems of an aircraft system. The RBF network is used as an ...

Identification and high bandwidth control of hard disk drive servo systems based on sampled data measurements
(2007)One of the key factors that determines the track density of a hard disk drive (HDD) is the performance characteristics of the HDD servo system, the control system that positions the READ/WRITE magnetic head close to the ...

Identification and reconstruction of a small leak zone in a pipe by a spectral element method
(2006)This paper deals with the identification of a zone permitting fluid to leak out of a drain. Using the analogy with crack identification by boundary measurements, we give uniqueness and stability results and we propose an ...

The Impact of Bootstrap Methods on Time Series Analysis
(2003)Sparked by Efron's seminal paper, the decade of the 1980s was a period of active research on bootstrap methods for independent data - mainly i.i.d. or regression set-ups. By contrast, in the 1990s much research was directed ...

Impact of head rotation on the individualized common carotid flow and carotid bifurcation hemodynamics
(2014)This paper aims at evaluating the changes that head rotation poses on morphological and flow characteristics of the carotid bifurcation (CB) and on the distribution of parameters that are regarded as important in atherosclerosis ...

Implicit-explicit BDF methods for the Kuramoto-Sivashinsky equation
(2004)We consider the periodic initial value problem for the Kuramoto-Sivashinsky (KS) equation. We approximate the solution by discretizing in time by implicit-explicit BDF schemes and in space by a pseudo-spectral method. We ...

An improved divergence information criterion for the determination of the order of an ar process
(2010)In this article we propose a modification of the recently introduced divergence information criterion (DIC, Mattheou et al., 2009) for the determination of the order of an autoregressive process and show that it is an ...

Improved Kansa RBF method for the solution of nonlinear boundary value problems
(2018)We apply the Kansa–radial basis function (RBF) collocation method to two-dimensional nonlinear boundary value problems. In it, the solution is approximated by a linear combination of RBFs and the governing equation and ...

Improved orders of approximation derived from interpolatory cubic splines
(1979)Let s be a cubic spline, with equally spaced knots on [a, b] interpolating a given function y at the knots. The parameters which determine s are used to construct a piecewise defined polynomial P of degree four. It is shown ...

Incompressible Poiseuille flows of Newtonian liquids with a pressure-dependent viscosity
(2011)The pressure-dependence of the viscosity becomes important in flows where high pressures are encountered. Applications include many polymer processing applications, microfluidics, fluid film lubrication, as well as simulations ...

Increased radiation exposure by granite used as natural tiling rock in Cypriot houses
(2007)This paper deals with gamma dose rates in Cypriot houses with and without granite flooring and compares the average radiation doses with one another. The additional radiation exposure due to granite flooring is compared ...

An indirect adaptive control design with anti-windup compensation: Stability analysis
(2007)We combine an adaptive law with a control design including a Linear Quadratic (LQ) controller and a Linear Matrix Inequality (LMI) based anti-windup compensator using the certainty equivalence principle for asymptotically ...

Indirect adaptive control for systems with input rate saturation
(2008)An indirect adaptive control design with anti-windup augmentation for stable systems subject to input magnitude saturation is extended to address systems with significant input rate constraints. We use the method of ...

Indirect questioning in sample surveys
(Springer-Verlag Berlin Heidelberg, 2013)Indirect questioning is a crucial topic in surveys of human populations. When the issue is about a stigmatizing characteristic (for example about illegal drug use), standard survey methodologies are destined to fail because, ...

Inequalities for trigonometric sums
(2012)We give a survey of recent results on positive trigonometric sums. Farreaching extensions and generalizations of classical results are presented. We provide new proofs as well as additional remarks and comments. We also ...

Inequalities for two sine polynomials
(2006)We prove: (I) For all integers n ≥ 2 and real numbers x ∈ (0, π) we have (Formula Presented) with the best possible constant bounds (Formula Presented) (II) The inequality (Formula Presented) holds for all even integers n ...
