We investigate the scattering of in-plane compressional (P) and shear (SV) waves by diamond shaped inclusions using a boundary element method. Special case that the shape of the diamond becomes square is also considered. Numerical results for some diamond shapes of the inclusion are obtained, and the effects of frequency on the scattering cross sections are discussed in detail. The response sim...

A novel analytical platform combining infrared attenuated total reflection (IR-ATR) spectroelectrochemistry (SE) with atomic force microscopy (AFM) using a boron-doped diamond (BDD)-modified ATR crystal is presented. The utility of this combination is demonstrated investigating the electrodeposition of a polymer film via IR spectroscopy, while the surface modification is simultaneously imaged b...

Control of the wetting property of diamond surface has been a challenge because of its maximal hardness and good chemical inertness. In this work, the micro/nanoarray structures etched into diamond film surfaces by a maskless plasma method are shown to fix a surface's wettability characteristics, and this means that the change in morphology is able to modulate the wettability of a diamond film ...

Abstract Rapidly spinning and loosely aggregated asteroids appear to take on diamond-shaped profiles, with elevated poles as well equators. The evolutionary processes that form these characteristic shapes remain a matter of debate. In this paper, we propose novel model, based debris accretion, explain profiles. We derive an analytic expression for the such rapidly rubble piles principle is depo...

In this paper, we propose a new hybrid Cross Hexagon Diamond Search algorithm (CHDS) using crossshaped search pattern as the initial step and asymmetric hexagon-shaped patterns and small diamond pattern as the subsequent steps for fast block motion estimation. In block motion estimation, search pattern with different shape or size and the center biased motion vector distribution characteristics...

BACKGROUND There is very little by way of clinical examination that helps in the diagnosis of subtypes of limb-girdle muscular dystrophy (LGMD). A small observation led to this study on a clinical sign in a group of 31 patients with dysferlinopathy that included 13 with LGMD-2B and 18 with Miyoshi myopathy (MM). The patients were asked to stand with knees slightly bent so that the quadriceps mu...

This paper proposes a new design method for two-dimensional diamond-shaped IIR filters. The design starts from a desired 1D prototype filter, to which a frequency transformation is applied, which leads to the 2D filter with desired shape. The frequency transformation is derived by specifying the filter shape in polar coordinates in the frequency plane. The designed filters also have the useful ...

Sharp FIR filters have very high implementation complexities. This is even more so for sharp 2-D FIR filters. In this paper, we introduce a new efficient approach for the synthesis of sharp diamond-shaped 2-D FIR filters using the frequency response masking technique. The design procedure as well as the parameters for the minimum complexity design are presented. A design example is also include...

This work is a contribution to the Spread Spectrum project for terrestrial HDTV broadcasting and focuses mainly on the coding of a low frequency signal with certain requirements. A new multiresolution decomposition scheme based on separable Diamond-shaped ltering is proposed. It takes advantage of Gaussian lters to extract smooth-looking frequency bands from the original signal. The deliberatel...
