Breaking the Limits - Redefining the Instantaneous Frequency
The Carson and Fry (1937) introduced the concept of variable frequency, required to the theory of frequency modulation (FM), as a generalization of the definition of constant frequency. Moreover, the nonstationary nature of the signals and nonlinear systems require the idea of instantaneous frequency (IF). It is also the basis of the time-frequencyenergy (TFE) analysis of a signal. The IF is th...
متن کاملOperative Laparoscopy: Redefining the Limits
The continually changing definition of operative laparoscopy as well as the ever-widening boundaries of its use are discussed in this report. It is important to prepare residents to adequately undertake advanced laparoscopic surgery as laparotomy is gradually replaced by laparoscopy for many routine procedures. Since degree of training and experience strongly correlate with complication rates, ...
متن کاملInstantaneous frequency estimation using the reassignment method
This paper explores the method of reassignment for extracting instantaneous frequency attributes from seismic data. The reassignment method was rst applied to the spectrogram by Kodera, Gendrin and de Villedary [5] and later generalized to any bilinear time-frequency or time-scale representation by Auger and Flandrin [1]. Key to the method is a nonlinear convolution where the value of the convo...
متن کاملSmart Polymeric Gels: Redefining the Limits of Biomedical Devices.
This review describes recent progresses in the development and applications of smart polymeric gels, especially in the context of biomedical devices. The review has been organized into three separate sections: defining the basis of smart properties in polymeric gels; describing representative stimuli to which these gels respond; and illustrating a sample application area, namely, microfluidics....
متن کاملKernel estimation of the instantaneous frequency
We consider kernel estimators of the instantaneous frequency of a slowly evolving sinusoid in white noise. The expected estimation error consists of two terms. The systematic bias error grows as the kernel halfwidth increases while the random error decreases. For a nonmodulated signal, g(t), the kernel halfwidth which minimizes the expected error scales as h ∼ [ σ2 N |∂2 t g |2 ]1/5 , where σ2 ...
