Statistical Mathematics of Ultrasonic Data (Analysis using R Language and Environment)

The Ultrasonic System Research Institute has published measurement and analysis data on ultrasonic sound pressure using its original product: an ultrasonic tester. << Measurement and Analysis of Ultrasonic Sound Pressure >> 1) By using feedback analysis through a multivariate autoregressive model, we will examine and evaluate the stability and changes of ultrasonic waves (many ultrasonic cleaning devices have issues in this regard). 2) Through the analysis of impulse response characteristics and autocorrelation, we will conduct examinations and evaluations related to tanks, transducers, and tooling (these are the most important parameters in ultrasonic processing). 3) By analyzing power contribution rates, we will examine and evaluate the optimization of ultrasonic (frequency and output), tanks, and liquid circulation (this examination is crucial for mass production devices). 4) Through nonlinear (bispectral) analysis of other factors (propagation of surface elastic waves), we will conduct examinations and evaluations tailored to the target object for cleaning, stirring, dispersion, and modification (this is necessary for research and development of ultrasonic utilization methods, including applications in nanotechnology). This analysis method is realized by adapting the measurement data to the dynamic characteristics of complex ultrasonic vibrations.

(Development of a control system based on ultrasonic measurement and analysis) The Ultrasonic System Research Institute has developed a technology that applies the measurement and analysis of the state of ultrasonic waves propagating in a liquid within an ultrasonic tank to set and control the propagation state of ultrasonic waves according to specific purposes, considering the influences of the tank's structure, strength, manufacturing conditions, and the state of liquid circulation. This technology analyzes and evaluates the dynamic characteristics of complex ultrasonic vibrations (Note 1) in relation to various factors, allowing for the setting of cavitation and acceleration effects according to specific objectives through the method of setting the circulation pump (Note 2). Note 1: This utilizes the original technology of the Ultrasonic System Research Institute, which considers "tone" in its "ultrasonic oscillation control" technology. Note 2: The know-how involves the relationship concerning the boundaries between the tank, circulating liquid, and air. It can also be applied to tanks that do not have an overflow structure. As a specific application, it is possible to set and control the propagation state of ultrasonic waves in the current tank to optimize the effects of cavitation and acceleration for the intended purpose as a power spectrum.

The Ultrasonic System Research Institute conducts consulting related to the use of ultrasound by applying feedback analysis technology based on multivariate autoregressive models, utilizing a technique for measuring, analyzing, and evaluating the propagation state of ultrasound. By organizing the measurements, analyses, and results obtained using ultrasonic testers in chronological order, we establish and confirm new evaluation criteria (parameters) that indicate the appropriate state of ultrasound for specific purposes. Note: Nonlinear characteristics (dynamic characteristics of acoustic flow), response characteristics, fluctuation characteristics, effects due to interactions, etc. By developing original measurement and analysis methods that consider the acoustic properties of the target object and surface elastic waves, we deepen our understanding of the relationships between various detailed effects related to vibrational phenomena, referencing statistical mathematical concepts. As a result, there is an increasing number of cases demonstrating the effectiveness of new nonlinear parameters related to the propagation state of ultrasound and the surface of the target object, such as changes in bispectrum and changes in autocorrelation. In particular, evaluation cases related to cleaning, processing, and surface treatment effects lead to successful control and improvement based on good confirmations.
