In this paper, a compact and simple structure of an elliptic microstrip lowpass filter (LPF) is designed for harmonic suppression in microwave quadrature hybrid coupler (QHC) applications. A radial resonator rectangular are used to produce LPF. The proposed LPF on the outer sides branch line coupler, which has improved suppression. Furthermore, artificial neural networks (ANNs) incorporated improve design process. best obtained using ANN model. size, only occupies 16.4 mm × 7.3 equals 0.164...
In this paper, it is aimed to perform clustering analysis on a large set of near-fault ground motions based the intensity velocity pulses. For purpose, pulses these are extracted asymmetric Gaussian chirplet model (AGCM), adapted dictionary-free orthogonal matching pursuit (ADOMP) algorithm, and Newton method. The location first AGCM atom considered as real pulse, its combination with adjacent atoms reconstructs pulse motions. addition, hierarchical k-means used cluster into two, three, five...
In two-class classification problems, due to the bias of machine learning algorithms towards majority class, from imbalanced data is one most challenging tasks. some studies, it has been shown that imbalance problem not only reason and other factors related nature data, such as small disjunct borderline rare examples, overlap between classes, shift are main reasons for this difficulty. To improve performance algorithms, here in paper, a hybrid sampling method proposed. First, feature space...
