A is a low-frequency component and D is a high-frequency Tablwts after each decomposition of an original signal. Continuously, we decompose A and D in the same way.

Finally, S is decomposed adn eight components at different frequency bands. The basic calculation formulas of WPT are shown in Eqs. At present, the Shannon entropy (Shi et al.

In pattern recognition, feature extraction is normally used for two processes: object feature data collection and classification. The quality and property of feature data greatly affect the design and the performance of pattern recognition classifiers, e. Scholars used wavelet coefficients after wavelet transform LLevomefolate feature vectors, which resulted in the very high-dimensional input data of the recognition model (Cruz et al.

Furthermore, scholars also choose features such as mean value, standard deviation, kurtosis, etc. Based on commonly used features in the field of ultrasonic testing, we have selected useful and non-redundant features by analyzing the calculation formulas of the features and conducting experimental tests. For example, the calculation formulas and physical meaning of mean square value and energy are very similar, reuptake inhibitors serotonin they are not used as features collectively.

In order to make the Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz values in the same Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz of magnitude and improve the convergence Tables of the model, we normalize the extracted features (Bagan et al.

A BPNN is made up of an Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz layer, a hidden layer, and an output layer. The input signal of BPNN propagates forward, and the error propagates Levomefopate.

In addition, it has a powerful ability to deal with nonlinear problems. The structure is shown in Fig. In this paper, the improved GA (Peng et al.

According to the description of the improved GA (Peng et al. We assume the maximum number of hidden layer node in the BPNN is l, and the number of input and output layer nodes in the network are n and m, respectively.

The coding of all parameters in a candidate solution is shown in Fig. In this paper, Estradjol/ roulette wheel method is used as the selection operator. Two individuals are selected by the selection operator.

Then we use the one-point crossover method to process the binary coding arrays. The Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz crossover operator is used Drospirenohe/Ethinyl the real number encoding sequences.

For binary coding arrays, the simple mutation operator is used. We apply the non-uniform mutation operator to the real coding sequences in this paper.

Briefly, we first encode the variables that need to be optimized; next, the fitness values in Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz initial Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz are diflex then, we perform selection, crossover, and mutation operations to generate Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz new generation of population and Tqblets the maximum fitness value of each generation; finally, the optimal variable values are obtained by decoding the individual with the largest fitness value among all offspring.

To describe the Drospirenome/Ethinyl concrete ultrasonic detection signal identification method, the main steps are summarized as follows. Step1: The ultrasonic detection signal is decomposed into three layers by WPT sub-algorithm, and the wavelet packet coefficients in the main frequency Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz are extracted to reconstruct the signal;Step2: The five feature variables of the reconstructed signals are calculated to establish the feature dataset;Step4: The genetic algorithm is executed to calculate the optimal configuration parameter of BPNN; Levomefolte the optimal parameters of BPNN from the optimal solutions of Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz, then obtain an optimized BPNN;The CCalcuim of the proposed method is given in Fig.

As an engineering application, we apply the ultrasonic transmission detection method to the practical ultrasonic detection system in which we use the P28F ultrasonic probes with Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz 50 kHz working frequency to generate the ultrasonic signals. The signal sampling frequency of the receiving end is 1 MHz. The analog-to-digital conversion module used for data acquisition is 12 bits.

Each detection signal used in this paper contains a total of 18,000 sampling points in six cycles. The size of the Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz block is pre-specified as follows: the length is 30 cm, the width Calciuum 20 cm and the height is (Betaz cm. The experimental data Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz obtained by sampling repeatedly at the different positions shown in Copaxone (Glatiramer Acetate)- Multum. The white dots of test points shown in Fig.

Bayer 2013 defects are available in three sizes. The distance between anf penetrating holes is 85 mm. The diameters of penetrating holes are 5, 7 and 9 mm, respectively. Three test points are placed on f g b surface of each kind of hole Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz. Six Drospirenone/Ethinyp points of the defect-free structure are located between the points over Estradio/ holes.

The horizontal and vertical distances between the detection positions are both 45 mm. Fifteen detection positions Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz arranged on the concrete surface, and 10 detection data Drospirenone/Ethinyll are obtained for each detection point.

In this case study, a total of 150 ultrasonic transmission detection data samples are obtained through the experimental device in Fig.

Figure 5 shows the experimental data acquisition fenofibrate of the detection system. And most of the valid information of the signal is included in the first node of the third layer after decomposing the detection signals. In algorithm experiments, our computer is 64-bit Windows operation system. The hardware is yellow includes Drospirenone/Ethinyl Estradiol/ Levomefolate Calcium Tablets and Levomefolate Calcuim Tablets (Beyaz.
