Ultrasonic modelling and simulation are widely used in inspection qualification by industrial non-destructive test. Due to limitation of inspection conditions and radiation environment inside the nuclear power plant, it is useful to study the application of ultrasonic simulation technology to in-service inspection in nuclear power plant. Simulation can be used to demonstrate the inspection capa...

An information-theory approach to Bayesian model class assessment is presented in this work for selecting the most plausible model class for soft-tissue-engineered consistence evolution. A set of candidate models based on the theory of Markov chains are proposed to idealize the temporal evolution of basic mechanical properties of an in-vitro tissue culture. Model parameters are first inferred f...

An optimization design method was proposed for linear phased array ultrasonic imaging testing. In the method, main lobe width and the amplitude ratio of side lobe to main lobe were served as optimization objectives to judge the testing precision of phased array beam directivity. The combination of element of width and inter-element space was served as optimize parameter for the optimization obj...

In the manufacturing of micro/nanocomposite materials, micro/nanoparticles need to be dispersed evenly into the base materials. However, due to their high surface-to-volume ratio and high surface energy, the micro/nanoparticles tend to agglomerate and cluster together. Ultrasonic cavitation is effective to disperse micro/nanoparticles. However, works on correlating the cavitation parameters wit...

The characterization of the signals in terms of linear/ nonlinear and deterministic/stochastic nature may be appropriated for knowledge extraction and machine learning algorithms. Some real-world signals exhibit signal modality characteristics that are strongly related with the physical mechanisms involved in the production of them. As an example, we can mention how the resonant sounds are more...

The ultrasonic velocity, density and viscosity at 318K have been measured in the binary systems of Methyl methacrylate + Toluene and Methyl methacrylate + Dimethylacetamide. In this work an attempt has been made for the first time to investigate the behavior of binary solutions of Methylmethacrylate(MMA) in Toluene and Dimethylacetamide(DMAC) with regard to acoustical parameters such as adiabat...

In this work, we have calculated analytically the temporal autocorrelation function of the electrical field component of multiply scattered coherent light transmitted through an anisotropically scattering media irradiated with a plane ultrasonic wave. The accuracy of the analytical solution is verified with an independent Monte Carlo simulation for different values of the ultrasonic and optical...

The literature does not present any information on ultrasonic assisted extraction of phenolic compounds from Coreopsis tinctoria Nutt. fruits using solvents with different polarities. The objective of this paper is to highlight the potential of ultrasound assisted extraction in the fast preparation of extracts rich in polyphenols of Coreopsis tinctoria Nutt. fruits in good yields. Several param...

Ultrasonic impedance has directly been measured for various binary mixtures using a novel experimental technique. The mixtures are dimethyl sulphoxide with benzene, carbon tetrachloride and methanol at 295 K in different mole fraction ratios. The acoustic impedance of binary mixtures thus obtained was found to be in good agreement with those calculated from experimentally measured ultrasonic ve...

The acoustic properties of aqueous solutions of dextran are characterized in the frequency range of 70-400 MHz by the bio-ultrasonic spectroscopy system using an ultrasonic transmission comparison method. The attenuation, velocity, impedance, and density of aqueous dextran solutions, for six molecular weights in the range of 10,400-2,000,000 Da in the concentration range 520% by weight, are rep...
