Acoustic Impedance Method

Research on the application of the acoustic impedance (AI) seismic inversion and multi-attribute method was conducted with the aim to characterize the reservoir in the Bonaparte Basin. The modeling which used in the acoustic impedance inversion seismic method is model-based. Meanwhile, the multi-attribute seismic method used log porosity that appliying the linear regression method and using the stepwise regression technique. Based on the result of the sensitivity analysis and analysis using the seismic inversion acoustic impedance method, the sandstone reservoir zone that has the prospect of hydrocarbons containing gas is located in the Northeast-Southwest part of the study area which in WCB-1, WCB-3 and WCB-4 well with the acoustic impedance values are in the range of 4,800 - 13,000 (m / s) * (g / cc), and the porosity values generated from the analysis using the multi-attribute seismic method are in the range of 5 - 16% in WCB-1 and WCB-4, 2 - 10% on WCB-3.

Multiple Actuators

A methodology to synthesize a predesignated acoustic response using a structure driven by multiple induced-strain actuators, e.g., piezoelectric (PZT) patches, is presented. The proposed approach of solving the inverse problem of structural acoustics, e.g., how to produce a known acoustic response from a given PZT-driven baffled plate, is accomplished using the impedance method. A dynamic model that assembles the PZT patch impedance, the host structure impedance, and the acoustic impedance is developed and then is utilized to synthesize a predesignated acoustic response. The proposed model includes the mass and stiffness of the actuator and thus provides a more accurate prediction when a structure is bonded with multiple actuators.

We use quartz crystal material from a physical point of constitutive equations derived in detail combined with the boundary conditions of the liquid Kanasawa QCM response model and Martin correction BVD equivalent circuit model; then apply transmission line theory and the theory of Acoustic impedance load, the research results can be useful as a QCM-D model, response model and Martin mode, then in-depth analysis of the liquid phase conditions, factors affecting the QCM frequency change, we propose a new method for measuring the density of the unknown liquid viscosity supplement. The main purpose of this chapter is to illustrate the viscous liquid medium under contact conditions, based on transmission line theory and the theory of load Acoustic impedance method compared to the classical method is simple, accurate, and effective.

ABSTRACTThe adhesion between metals and polymers is normally weak because they have drastically different electronic properties and interfacial bonding between metals and organic polymers is not readily affected by conventional coating techniques. The ion beam enhanced deposition (IBED) approach to improve adhesion focuses on the promotion of non-equilibrium “interdiffusion” and the creation of nucleation sites at the interfaces by low energy ion bombardment before and during metal deposition onto the polymer substrate.The results of our work show a significant improvement of adhesion at the metal (Au)/polymer (Teflon) interface.
