Sound morphing is one of the successful synthesis technologies for recent computer music, and several studies have been reported on this subject. We have proposed a sound morphing algorithm based on a sinusoidal model. In this paper, a correspondence search algorithm is improved, which is core technology of morphing based on a sinusoidal model. Then wider applications of the algorithm are intro...

Probability theory is applied to the problem of estimating the amplitudes of the sinusoids in nuclear magnetic resonance data containing two exponentially decaying sinusoids. The posterior probability-density of one of the amplitudes is derived independent of the phases, frequencies, decay-rate constants, variance of the noise, and the amplitude of the other sinusoid. This probability-density f...

Approximate and rigorous methods are widely used to model light scattering from a surface. The boundary element method (BEM) is that accounts for polarization multiple effects. BEM suitable the scattered surfaces with complex geometries containing overhangs re-entrant features. Beckmann–Kirchhoff (BK) model, which an approximate can be predict behavior of slowly varying surfaces. Although BK ca...

light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...

A quantitative approach to the Makyoh-topography image formation mechanism is presented. General relations are given on the optical settings; geometrical optical simulations of a sinusoidal surface and a hillock (or depression) are presented. Optimum working conditions are established, and general features of the imaging are pointed out. The experimental images taken for Si wafers are compared ...

A numerical study employing discontinuous Galerkin method demonstrating net surface heat reduction for a cylindrical body in Mach 17 hypersonic flow is presented. This application focuses on using sinusoidal dielectric barrier discharge plasma actuators to inject momentum near the stagnation point. A 5 species finite rate air chemistry model completes the picture by analyzing the effect of the ...

This paper presents a parametric solution to the problem of estimating the orientation in space of a planar textured surface, from a single, noisy, observed image of it. The coordinate transformation from surface to image coordinates, due to the perspective projection, transforms each homogeneous sinusoidal component of the surface texture into a sinusoid whose frequency is a function of locati...

The paper compares and optimizes through modeling conductive polymer composite slabs having different architectures of corrugated surfaces, designed to minimize both the reflectivity its sensitivity angle incidence a microwave/millimeter wave signal impinging on surface slab. Simulations using CST Studio software consider Poly-Lactid-Acid as dielectric material since it is widely used for 3D pr...

Rotation of the illuminant source about a subject textured surface can cause catastrophic failure of texture classification schemes. This is due to the variation of texture feature output that can occur when the illuminant direction is varied. This paper uses theory and experiment to show that the outputs of linear texture filters, and their features, are sinusoidal functions of the illuminant’...
