Wavelet instruments for efficiency gains in generalized method of moment models
(2007)We propose a simple computational method in the context of generalized method of moments for improving the efficiency of regression coefficient estimates. The gains in efficiency arise by incorporating additional moment ...

Wavelet methods for continuous-time prediction using Hilbert-valued autoregressive processes
(2003)We consider the prediction problem of a continuous-time stochastic process on an entire time-interval in terms of its recent past. The approach we adopt is based on the notion of autoregressive Hilbert processes that ...

Wavelet packet transfer function modelling of nonstationary time series
(2002)This article shows how a non-decimated wavelet packet transform (NWPT) can be used to model a response time series, Yt in terms of an explanatory time series, Xt. The proposed computational technique transform the explanatory ...

Wavelet shrinkage for natural exponential families with quadratic variance functions
(2001)We propose a wavelet shrinkage methodology for univariate natural exponential families with quadratic variance functions, covering the Gaussian, Poisson, gamma, binomial, negative binomial and generalised hyperbolic secant ...

Wavelet thresholding via a Bayesian approach
(1998)We discuss a Bayesian formalism which gives rise to a type of wavelet threshold estimation in nonparametric regression. A prior distribution is imposed on the wavelet coefficients of the unknown response function, designed ...

Wavelet transform modulus maxima decay lines: Damage detection in varying operating conditions
(IGI Global, 2015)An important task in structural health monitoring (SHM) is that of damage detection under varying environmental and operational conditions. Structures, under varying environmental conditions, change their mass, elasticity ...

Ways of portraying science ideas on the internet and their interaction with science education
(Department of Educational Sciences, University of Cyprus, 2003)In this work, Internet serves as a field of research for the study of the various ways of visual representation on several scientific areas. The variety of sources on the Internet allows the detection of alternative ways ...

Ways to increase adherence to allergen immunotherapy
(2019)Adherence to allergen immunotherapy (AIT) is crucial for its efficacy. Subcutaneous AIT requires monthly visits (or more extended in the case of venom immunotherapy), while sublingual AIT is performed with a daily intake ...

Weak bisimulation for probabilistic systems
(2000)In this paper, we introduce weak bisimulation in the framework of Labeled Concurrent Markov Chains, that is, probabilistic transition systems which exhibit both probabilistic and nondeterministic behavior. By resolving the ...

Weak convergence of dependent empirical measures with application to subsampling in function spaces
(1999)Consider the problem of inference for a parameter of a stationary time series, where the parameter takes values in a metric space (such as a function space). In this paper, we develop asymptotic theory based on subsampling ...

Weak e+e- lines from internal pair conversion observed in collisions of 238U with heavy nuclei
(1998)We present the results of a Doppler-shift correction to the measured e+e--sum-energy spectra obtained from e+e--coincidence measurements in 238U + 206Pb and 238U + 181Ta collisions at beam energies close to the Coulomb ...
