In order to resolve engineering problems that the performance of traditional blind source separation (BSS) methods deteriorates or even becomes invalid when unknown signals are interfered by impulse noise with a low signal-to-noise ratio (SNR), more effective and robust BSS method is proposed. Based on dual-parameter variable tailing (DPVT) transformation function, moving average filtering (MAF...

This paper presents a methodology based on the collocation multiquadric radial basis functions to analyze the static and dynamic behavior of isotropic rectangular plates. The inertia and dissipative terms are evaluated by employing Newmark implicit time marching scheme. The spatial discretization of the differential equations generates greater number of algebraic equations than the unknown coef...

ii Preface Radial Basis Function (RBF) methods have become the primary tool for interpolating multidimensional scattered data. RBF methods also have become important tools for solving Partial Differential Equations (PDEs) in complexly shaped domains. Classical methods for the numerical solution of PDEs (finite difference, finite element, finite volume, and pseudospectral methods) are based on p...

OBJECTIVE Mometasone furoate (MF) is a new, potent synthetic inhaled corticosteroid. Worldwide, MF is administered via a dry-powder inhaler that contains multiple doses. As a preparation that would be more cost-effective, single-dose MF capsules were developed in Brazil. The objective of the present study was to evaluate the efficacy and safety of the two inhalers for MF administration in patie...

We present a measurement of the evolution of the stellar mass function (MF) of galaxies and the evolution of the total stellar mass density at 0 < z < 5, extending previous measurements to higher redshift and fainter magnitudes (and lower masses). We use deep multicolor data in the Fors Deep Field (FDF; I-selected reaching IAB ∼ 26.8) and the GOODS-S/CDFS region (K-selected reaching KAB ∼ 25.4)...

Elliptic boundary value problems (BVPs) are widely used in various scientific and engineering disciplines that involve finding solutions to elliptic partial differential equations subject certain conditions. This article introduces a novel approach for solving BVPs using an artificial neural network (ANN)-based radial basis function (RBF) collocation method. In this study, the backpropagation i...

introduction studies about the health effects of long-term average exposure to outdoor air pollution have played an important role in the recent health impact assessments. exposure assessment for epidemiological studies of long-term exposure to ambient air pollution remains a difficult challenge because of substantial small-scale spatial variation. current approaches for assessing intra-urban ai...

Mycosis fungoides (MF) is the most common form of cutaneous T-cell lymphoma. Persistent antigenic stimulation has been claimed to play a role in the development of this malignancy. We aimed to show the role of sulfur mustard in the pathogenesis of MF. A 45-year-old man with MF is introduced herein. He was a victim of chemical exposure in 1987 during the Iran–Iraq war. He developed skin lesions ...
