Background: Triple therapy with a proton pump inhibitor, c1arithromycin and amoxicillin and quadruple therapy with a proton pump inhibitor, bismuth citrate, met­ ronidazole and amoxicillin have been proposed in Maastricht 2000 as the optimal treat­ ment of Helicobacter pylori infection. We aimed to compare these two regimens in Iranian pediatric patients. Methods: A randomized clinical trial in...

Two systems are presented for compression of hyperspectral imagery. These systems utilize adaptive classification, trellis-coded quantization, and optimal rate allocation. In the first system, DPCM is used for spectral decorrelation, while an adaptive wavelet-based coding scheme is used for spatial decorrelation. The second system uses DPCM in conjunction with an adaptive DCT-based coding schem...

Abstract: Traditional 2-D Discrete wavelets transform (DWT) implemented by separable 1-D transform in horizontal and vertical directions does not take image orientation features in a local window into account. However, the lifting scheme provides a general and flexible tool for the construction of wavelet decompositions and perfect reconstruction filter banks. To improve it, we propose to intro...

An interesting scheme for estimating and adapting distributions in real-time for non-stationary data has recently been the focus of study for several different tasks relating to time series and data mining, namely change point detection, outlier detection and online compression/ sequence prediction. An appealing feature is that unlike more sophisticated procedures, it is as fast as the related ...

This paper proposes a new bilateral control scheme to ensure both transparency and robust stability under unknown constant time delay in stiff environment. Furthermore, this method guaranties suitable performance and robust stability when transition occurs between soft and stiff environments. This framework is composed of an adaptive sliding mode controller and an adaptive impedance controller,...

This article presents an improved adaptive sampling scheme for the construction of explicit decision functions (constraints or limit state functions) using Support Vector Machines (SVMs). The proposed work presents substantial modifications to an earlier version of the scheme (Basudhar and Missoum, Comput Struct 86(19–20):1904– 1917, 2008). The improvements consist of a different choice of samp...
