This paper presents an incremental method to 3D transformation by VQS structures. For interpolated scaling, rotation and translation between two animation key frames, with constant intervals in size, angle and distance, the proposed approach reduces the VQS transformation cost by more than an half. Moreover, all interpolations for VQS key frames are performed implicitly at no cost. In other wor...

⎯This paper proposes fractal patterns for power quality (PQ) detection using color relational analysis (CRA) based classifier. Iterated function system (IFS) uses the non-linear interpolation in the map and uses similarity maps to construct various fractal patterns of power quality disturbances, including harmonics, voltage sag, voltage swell, voltage sag involving harmonics, voltage swell invo...

We investigate anisotropical and geometrical aspects of hexagonal structures of Silicon Carbide and propose a direction dependent interpolation method for oxidation growth rates. We compute threedimensional oxidation rates and perform one-, two-, and three-dimensional simulations for 4Hand 6H-Silicon Carbide thermal oxidation. The rates of oxidation are computed according to the four known grow...

Fuzzy Hermite interpolation of 5th degree generalizes Lagrange interpolation by fitting a polynomial to a function f that not only interpolates f at each knot but also interpolates two number of consecutive Generalized Hukuhara derivatives of f at each knot. The provided solution for the 5th degree fuzzy Hermite interpolation problem in this paper is based on cardinal basis functions linear com...

an accurate design of drip irrigation requires water quality analysis that helps attain a better emission uniformity coefficient. this study examined aquifer qualitative parameters in the north of khuzestan province to assess the applicability of groundwater in trickle irrigation systems. for this purpose, interpolation technology was used to map chemical parameters collected from 104 deep well...

This work describes an auto-calibrated method for parallel imaging with spiral trajectory. The method is a k-space approach where an interpolation kernel, accounting for coil sensitivity factors, is derived from experimental data and used to interpolate the reduced data set in parallel imaging to estimate the missing k-space data. For the case of spiral imaging, this interpolation kernel is def...

We present the theory and numerical results for interferometrically interpolating and extrapolating ocean bottom seismic (OBS) data. For the interpolation of OBS data we use the combination of a natural Green’s function (i.e. OBS shot gather) and a model-based Green’s function for the water-layer model. Synthetic and field data results show that the aliased OBS data with large receiver interval...

Based on enhanced interpolation DFT, a novel parameter estimation algorithm for the exponential signal is presented. The proposed two-step solution consists of a preprocessing unit which constructs a new signal sequence by continuously cycle shifting sample points and summing up N buffered exponential signal sample sequences, then an interpolation DFT engine to obtain accurate parameter estimat...

CT Colonography (CTC) is an emerging imaging technique for colon screening. It is possible to extend this technique to automatically detect colonic anomalies. In order to improve the detection rate of the potential polyps, it is desirable to analyse plane sections orthogonal to the colon centreline rather than the axial CT slices. This paper describes a fast artefact free method for orthogonal ...

Acoustic radiation force impulse (ARFI) imaging is being utilized to investigate mechanical properties ofcardiac tissue. The underlying physiological motion, however, presents a major challenge. This paper aims to investigate the effectiveness of various physiological motion filters using in vivo canine data with a simulated ARFI push pulse. Ideally, the motion filter will exactly model the phy...
