Abstract Tilapia ( Oreochromis niloticus ) holds a major position in the fishery market worldwide. This study aimed to investigate effect of four drying methods, namely vacuum freeze (VFD), microwave (VMD), hot air (HAD) and (MD), on texture, amino acids, microstructure, lipid oxidation protein degradation tilapia fillets. The results showed that combined with refrigeration (VFD) or VMD had bet...

Abstract In order to solve the problem of recognition error caused by noise interference in oil and gas pipeline signal traditional leakage detection relies on expert experience extract features manually, an model based deep learning is proposed this paper. The consists data preprocessing part pattern part. Firstly, a denoising algorithm variational mode decomposition (VMD) Manhattan distance (...

Abstract To address the problem of low accuracy fault information extracted from motor-bearing vibration signals, a feature extraction method based on Whale Optimization Algorithm (WOA)-Variable Modal Decomposition (VMD) energy entropy is proposed, and modified WOA-Support Vector Machine (SVM) used for diagnosis. Firstly, optimal number modes K penalty parameters α variable modal decomposition ...

Submerged vacuum membrane distillation (S-VMD) is a thermally driven separation process capable of desalinating water with high salt concentration. Agitation techniques such as aeration and circulation have been used to enhance the permeate flux mitigate effect temperature concentration polarizations, major drawback in S-VMD. In this study, an S-VMD system that uses ultrasonic energy agitation ...

A Finite Energy QCD sum rule at non-zero temperature is used to determine the q2and the T dependence of the ρππ vertex function in the space-like region. A comparison with an independent QCD determination of the electromagnetic pion form factor Fπ at T 6= 0 indicates that Vector Meson Dominance holds to a very good approximation at finite temperature. At the same time, analytical evidence for d...

The leakage of the ship’s pipeline system will bring great risks to engine equipment and seriously threaten vitality ship. In this paper, detection localization research are carried out based on vibration signal generated by leakage. First, finite element model is constructed obtain variation law when leaks out. Second, processed variational mode decomposition (VMD) radial basis function (RBF) ...

Variational Mode Decomposition (VMD) is widely used for inspection purposes. The initial parameters are usually set manually, which a limitation of this technique. In paper, method to automatically select these through combination Singular Value (SVD) and Improved-VMD (IVMD) proposed. VMD applied multiple times with varying K-value parameter. original signal its sub-signals arising from decompo...

Studies of τ mesonic decays are presented. A mechanism for axial-vector current at low energies is proposed. The VMD is used to treat the vector current. All the meson vertices of both normal parity and abnormal parity (Wess-Zumino-Witten anomaly) are obtained from an effective chiral theory of mesons. a 1 dominance is found in the decay modes of τ lepton: 3π, f (1285)π. Both the ρ and the a 1 ...

A Drell-Yan type calculation of $(3100) photoproduction based on the recent data from SPEAR gives a surprisingly large cross section. If the results of the photoproduction experiment at FNAL are similar to naive VMD expectations, a stringent upper bound on charmed quarks in nucleons is obtained. A consequence for vWz at high o is also noted. (Submitted to Phys. Rev. Letters) * Work supported by...
