Deployment of the meta heuristic Colonial Competitive Algorithm in synthesis of unequally spaced linear antenna array
In this paper we re-call a recently developed meta heuristic optimization algorithm based on socio-political process of imperialistic competition. This Colonial Competitive Algorithm (CCA) has shown its efficient capability in comparison to convenient optimization algorithms like GA, PSO. In this study we investigate the synthesis problem of unequally linear space antenna using CCA and show the...
متن کاملWavelet Shrinkage for Unequally Spaced Data Wavelet Shrinkage for Unequally Spaced Data
Wavelet shrinkage (WaveShrink) is a relatively new technique for nonparametric function estimation that has been shown to have asymptotic near-optimality properties over a wide class of functions. As originally formulated by Donoho and Johnstone, WaveShrink assumes equally spaced data. Because so many statistical applications (e.g., scatterplot smoothing) naturally involve unequally spaced data...

متن کاملBayesian interpolation of unequally spaced time series
A comparative analysis of time series is not feasible if the observation times are different. Not even a simple dispersion diagram is possible. In this article we propose a Gaussian process model to interpolate an unequally spaced time series and produce predictions for equally spaced observation times. The dependence between two observations is assumed a function of the time differences. The n...
متن کاملAlgorithms for Unequally Spaced Fast Laplace Transforms
Vol. 1 (2013) pp. 37-46. ALGORITHMS FOR UNEQUALLY SPACED FAST LAPLACE TRANSFORMS FREDRIK ANDERSSON⇤ Abstract. We develop fast algorithms for unequally spaced discrete Laplace transforms with complex parameters, which are approximate up to prescribed choice of computational precision. The algorithms are based on modifications of algorithms for unequally spaced fast Fourier transforms using Gauss...
