Through piecewise linearization, the control equation of gas migration in coal is simplified to a parabolic differential with time-dependent source terms, and under corresponding initial conditions, boundary additional conditions are used obtain definite solution unknown function identification equation. A triaxial experimental device measure axial pressure specimen independently developed, tes...

INTRODUCTION: Diffusion MRI is a unique noninvasive imaging technique capable of quantifying and visualizing the angular distribution and the anisotropy of the white matter fibers. Several approaches such as diffusion tensor imaging, q-ball imaging (QBI), spherical deconvolution and many others high angular resolution diffusion imaging (HARDI) have been proposed to describe the angular distribu...

S U M M A R Y The method of generalized cross-validation (GCV) has been widely used to determine the regularization parameter, because the criterion minimizes the average predicted residuals of measured data and depends solely on data. The data-driven advantage is valid only if the variance–covariance matrix of the data can be represented as the product of a given positive definite matrix and a...

 Pendekatan regresi nonparametrik Kernel digunakan untuk memperkirakan harapan bersyarat dari variabel dependen terhadap independen tanpa mengasumsikan bentuk parametrik tertentu. ini menggunakan fungsi sebagai alat melakukan estimasi. Dalam penelitian ini, Gaussian dan estimator Nadaraya-Watson. Estimator Nadaraya-Watson adalah metode yang mengestimasi rata-rata tertimbang secara ...

Longitudinal data modeling is widely carried out using parametric methods. However, when the model misspecified, obtained estimator might be severely biased and lead to erroneous conclusions. In this study, we propose a new estimation method for longitudinal mixed in nonparametric regression. The objective of study was estimate regression curve two combined estimators: truncated spline local li...

A new technique is proposed to estimate the robust continuous observation densities of hidden Markov model (HMM) for improving the performance of speaker-independent (SI) automatic speech recognition system. First, a scheme of generalized common vector (GCV), which originated from the common vector approach (CVA), is proposed. The objective of this scheme is to extract a robust speech feature o...

one of the main steps within the geoid computation methodology without applying the stokes formula is downward continuation of the harmonic residual observables from the surface of the earth down to the surface of the reference ellipsoid. this downward continuation is done via the abel-poisson integral and its derivatives. this integral in which the unknowns, i.e. harmonic residual potential va...
