A confidence interval is an interval (i.e., a range of values) estimate of a parameter of a population (e.g., a mean) calculated from a sample drawn from the population. A confidence interval has an associated confidence level, which is frequency with which a calculated confidence interval is expected to contain the population parameter. Confidence intervals are of interest in modeling and simu...

We treat a challenging problem of confidentiality-preserving data publishing: how to repeatedly update a released weakened view under a modification of the input parameter values, while continuously enforcing the confidentiality policy, i.e., without revealing a prohibited piece of information, neither for the updated view nor retrospectively for the previous versions of the view. In our semant...

When data are poor, we resort to theory modeling. This is a two-step process. We have first to identify the appropriate type of model for the system under consideration and then to tailor it to the specifics of the case. To understand settlement formation, which is the concern of this article, this involves choosing not only input parameter values such as site separations but also input functio...

Many cardiovascular diseases will lead to changes in pulse wave. Pulse wave’s transmission will play a significant role in promoting the clinical detection and diagnosis, one kind pulse wave computational method based on averaging method is proposed, and computing cardiovascular function parameter K according to the waveform area, the K value is associated with pathological analysis and diagnos...

The dynamical behaviour of the forced escape oscillator, which depends on the parameter values we considered, have been studied numerically using the techniques of phase portraits and Poincar'{e} sections. Also, we employed perturbation methods such as Lindstedt's method to obtain the frequency-amplitude relation of escape oscillator.

The parameter-induced stochastic resonance (SR) phenomenon in a novel self-adaptive dynamical system driven by linear frequency modulated (LFM) signal and additive noise is considered from the view of the signal-to-noise ratio (SNR). It is found that the dynamical system can be perfectly analyzed by equivalently transforming it into a traditional firstorder linear dynamical system driven by per...

In this study, a blind carrier frequency offset (CFO) estimation method is proposed using the time-frequency symmetry of transmitted signals weighted Fourier transform (WFrFT) communication system. Blind CFO achieved by focusing on property that results in matching signal waveforms before and after when WFrFT parameter set to certain value. Numerical simulations confirm more resistant Rayleigh ...

Frequency shift keying (FSK) signal has been widely used in modern radar systems. To intercept the FSK with a high interception probability, reconnaissance receiver should have an ultra-wideband receiving ability. The Nyquist folding (NYFR) is novel non-cooperative and it requires small amount of equipment. When intercepted by NYFR, corresponding output hybrid modulation signal. Therefore, nece...
