Novel strategies based on spray-pyrolysis deposition are proposed to increase the triple-phase boundary (TPB) of La0.8Sr0.2MnO3-δ (LSM) cathodes in contact with yttria-stabilized zirconia (YSZ) electrolyte: (i) nanocrystalline LSM films deposited on as-prepared YSZ surface; (ii) the addition of poly(methyl methacrylate) microspheres as pore formers to further increase the porosity of the film c...

This study describes a hybrid technique for identification of buried objects. The object’s shape and electromagnetic profile are reconstructed from evaluations of electrical permittivity and conductivity. The method suggests a combination of linear sampling and optimization. Linear sampling method (LSM) is used to recover shape and metaheuristic optimizations essential to reconstruct the inside...

Watershed transformation in mathematical morphology is a powerful tool for image segmentation. Watershed transformation based segmentation is generally a marker-controlled segmentation. This paper proposes a novel method of maker image generation based on unsupervised ISODATA classification. The method incorporates spectral information contained in multispectral data into watershed transformati...

Least squares migration (LSM) is applied to synthetic data with the purpose of removing the ”acquisition footprint” noise from migrated sections. Results for simple point scatterer and meandering stream channel models suggest that LSM can significantly attenuate the acquisition footprint noise. For comparison, the corresponding Kirchhoff migrated sections show noticeable artifacts due to a coar...

It is important to have the accuracy sorting plan for the save of postman work time and the fast delivery of the receipt mail. It’s also very important to plan the proper carrier sorting plan at the situation where the number of pocket of letter sorting machine [LSM] is less than the number of postal code or the number of carrier. This paper describes the method for the carrier sorting plan and...

Backscatter and attenuation variations are essential contrast mechanisms in ultrasound B-mode imaging. Emerging quantitative ultrasound methods extract and display absolute values of these tissue properties. However, in clinical applications, backscatter and attenuation parameters sometimes are not easily measured because of tissues inhomogeneities above the region-of-interest (ROI). We describ...

Abstract. The watershed transform and the morphological reconstruction are two of the most important operators for image segmentation in the framework of mathematical morphology. In many situations, the segmentation requires the classical watershed transform of a reconstructed image. In this paper, we introduce the IFT-watershed from gray scale marker a method to compute at same time, the recon...
