Logarithmic curve interpolation is essential for precise machining conical cutters with constant rake and spiral angle in CNC machine. In this paper, a novel odd-even steps third order approach algorithm is presented to realize the logarithmic interpolation. In each interpolating cycle there are odd and even steps divided. At the odd step, the interpolating point moves in tangent direction for ...

In this paper we present three theoretically grounded methods: prediction, reconstruction and interpolation, for measuring cross traffic on the bottleneck link of an end-toend path. The objective is to infer cross traffic as accurately as possible, while not injecting a significant amount of probe packets into the network. In the prediction-based method, we take advantage of the LRD characteris...

In fuzzy time series analysis, the determination of the interval length is an important issue. In many researches recently done, the length of intervals has been intuitively determined. In order to efficiently determine the length of intervals, two approaches which are based on the average and the distribution have been proposed by Huarng [4]. In this paper, we propose a new method based on the...

For n 1, let fxjngnj=1 be n distinct points in a compact set K R and let Ln[ ] denote the corresponding Lagrange Interpolation operator. Let v be a suitably restricted function on K. What conditions on the array fxjng1 j n; n 1 ensure the existence of p > 0 such that lim n!1 k (f Ln[f ]) v kLp(K)= 0 for every continuous f :: K ! R ? We show that it is necessary and su cient that there exists r ...

watermarking implant information into a digital signal like audio, Picture, or video. Reversible Picture watermarking can bring back the original picture without any distortion after the hidden data is extracted. In this paper, we present a novel reversible watermarking scheme using an interpolation procedure, which can embed a large amount of covert data into Pictures with imperceptible modifi...

An adaptive decision based inverse distance weighted interpolation (DBIDWI) algorithm for the elimination of highdensity salt and pepper noise in images is proposed. The pixel is initially checked for salt and pepper noise. If classified as noisy pixel, replace it with an inverse distance weighted interpolation value. This interpolation estimates the values of corrupted pixels using the distanc...

background and objectives: in sciences like ecology, that measured value of a quantity to be processed within a definite border, the estimation of variable values in a particular time and place, using existing data from the use of information variable or variables another is common. in geoeographic studies, data collection is often the point. usually, it is essential that this data be generaliz...

Background: Medical image interpolation is recently introduced as a helpful tool to obtain further information via initial available images taken by tomography systems. To do this, deformable image registration algorithms are mainly utilized to perform image interpolation using tomography images.Materials and Methods: In this work, 4DCT thoracic images of five real patients provided by DI...

In this paper, Kriging has been chosen as the method for surrogate construction. The basic idea behind Kriging is to use a weighted linear combination of known function values to predict a function value at a place where it is not known. Kriging attempts to determine the best combination of weights in order to minimize the error in the estimated function value. Because the actual function value...
