A Fast and Accurate Multilevel Inversion of the Radon Transform

A number of imaging technologies reconstruct an image function from its Radon projection using the convolution backprojection method. The convolution is an O(N2 logN) algorithm, where the image consists of N×N pixels, while the backprojection is an O(N3) algorithm, thus constituting the major computational burden of the convolution backprojection method. An O(N2 logN) multilevel backprojection ...

Fast and Accurate Feature Selection Using Hybrid Genetic Strategies

When dealing with object classification, each object is defined by a set of features (characteristics) that classify the object to a particular class. The problem is how to choose the best subset of characteristics that provide an accurate classification. Previous research has shown that Decision tables are as accurate as C4.5 for classification purposes. Two different genetic search techniques...

A New Fast and Accurate Fault Location and Classification Method on MTDC Microgrids Using Current Injection Technique, Traveling-Waves, Online Wavelet, and Mathematical Morphology

In this paper, a new fast and accurate method for fault detection, location, and classification on multi-terminal DC (MTDC) distribution networks connected to renewable energy and energy storages presented. MTDC networks develop due to some issues such as DC resources and loads expanding, and try to the power quality increasing. It is important to recognize the fault type and location in order ...

Harmonics Estimation in Power Systems using a Fast Hybrid Algorithm

In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
