Direct investigation of, and interaction with, biological objects at the macromolecular level will provide insight into multiple physical regulatory processes. Scanning probe microscopy (SPM) techniques have the potential to provide a direct interaction with living specimens at the macromolecular scale. In the present research we will discuss the site-specific recognition techniques that are ap...

The short-time Fourier transform (STFT) and the continuous wavelet transform (CWT) are used to analyze the time course of cellular motion in the inner ear. The velocity responses of individual outer hair cells and Hensen’s cells to sinusoidal and amplitude modulated (AM) acoustical signals applied at the ear canal display characteristics typical of nonlinear systems, including the generation of...

In this paper, a novel method for analysis of binaural room impulse responses is presented. Individual reflections are localized in time and frequency from a measured binaural room impulse response based on the continuous cross-wavelet transform (XWT). The directions of the reflections are then analyzed based on KEMAR and CIPIC reference data lookup, and compared a previous approach. Analysis o...

In this paper, some time-frequency analysis methods were studied to get the detailed characteristics of two-way automatic communication system (TWACS) outbound signal sampled from industry power network with high disturbance, . Compared with traditional time-domain detecting algorithm, time-frequency analysis methods, including short-time Fourier transform (STFT)), Wigner distribution (WD) and ...

In this paper,. an novel method based on the phase information of continuous wavelet transform to estimate the instantaneous parameter of AM-FM signal is introduced, and some strategies, including the determination of initial value in iteration and post-processing to the estimated results, to improve the performance of the algorithm are proposed. Compared to several other instantaneous paramete...

This paper describes an approach to image modelling using interscale phase relationships of wavelet coefficients for use in image estimation applications. The method is based on the Dual Tree Complex Wavelet Transform (DT-CWT) but a phase rotation is applied to the coefficients to create complex ‘derotated’ coefficients. These derotated coefficients are shown to have increased correlation compa...

Advanced signal processing techniques have been long introduced and widely used in structural health monitoring (SHM) and nondestructive evaluation (NDE). In our research, we applied several signal processing approaches for our embedded ultrasonic structural radar (EUSR) system to obtain improved damage detection results. The EUSR algorithm was developed to detect defects within a large area of...

P-wave characteristics in the human ECG are an important source of information in the diagnosis of atrial conduction pathology. However, diagnosis by visual inspection is a difficult task since the P-wave is relatively small and noise masking is often present. This paper introduces novel wavelet characteristics derived from the continuous wavelet transform (CWT) which are shown to be potentiall...

The article discusses the new technique for fracture closure pressure detection using continuous wavelet transform (CWT). study focuses on calibrating CWT and comparing it with different techniques detection. According to article, traditional methods identifying of hydraulic fracturing operations are based assumptions that can conflict one another, resulting in greatly varying approximations du...
