Since the discovery that the best error-correcting decoding algorithm can be viewed as belief propagation in a cycle-bound graph, researchers have been trying to determine under what circumstances "loopy belief propagation" is effective for probabilistic inference. Despite several theoretical advances in our understanding of loopy belief propagation, to our knowledge, the only problem that has ...

A method of signal waveform estimation from an ensemble of jittered noisy measurements is presented. The method uses group delay functions to perform the ensemble averaging and thus overcomes the difficulty of computing the unwrapped phase function before averaging. We propose a new technique, called group delay processing, to estimate the signal waveform if only a single noisy measurement is a...

Design of time-frequency distributions (TFDs) that are robust to the impulse noise influence is considered. The robust TFDs based on the robust short-time Fourier transform (STFT) are proposed. An efficient procedure to evaluate the robust STFT is given. Robust TFDs based on the robust STFT have better energy concentration around the signal instantaneous frequency (IF) than the robust STFT itse...

In this paper differential SAR-Interferometry (DInSAR) is applied to study a landslide close to La Valette which is situated in the southern French Alps. The general capability of D-InSAR to determine the field of movement of a moderately moving landslide is shown, by carrying out the phase unwrapping and projecting the measured displacement to the direction of the movement. The data analysed i...

Concentrations and loadings (output, number day-' km-2) of fecal coliform (FC) indicator bacteria were measured from 1979 through 1984 in streamflow from 13 forested watersheds under the following range management strategies: (A) no grazing; (B) grazing without management for livestock distribution; (C) grazing with management to obtain livestock distribution, and (ID) grazing with management t...

duopoly game theory is applied to the wood industrial markets (sawnwood and pulpwood markets) in the north of iran. the nash equilibrium and the dynamic properties of the system based on marginal adjustments are determined. the probability that the nash equilibrium will be reached is almost zero. the dynamical properties of sawnwood and pulpwood prices derived via the duopoly game model are fou...

Current climate models demonstrate large discrepancy in equilibrium sensitivity (ECS). The effects of cloudiness parameterization changes on the ECS INM-CM4-8 model were investigated. This shows lowest among CMIP6 models. Reasonable degree yielded variability 1.8–4.1 K INM-CM4-8, which was more than half interval for three principal mechanisms responsible increased dissipation warmer climates d...

Teager Energy Operator (TEO) proposed by Kaiser and Teager is based on a definition of energy required to generate the signal. TEO gives us the running estimate of energy as a function of amplitude and instantaneous frequency content of the signal. However, it considers three consecutive samples to calculate the energy estimate. In this paper, we suggests an alternative and generalized approach...

It is often claimed that instantaneous frequency, taken as the derivative of the phase of the signal, is appropriate or meaningful only for mono-component signals, and that for multi-component signals a weighted average of individual instantaneous frequencies should be used. In this paper, we show if a signal is decomposed adaptively and we compute the matching pursuit distribution, then the fi...

This paper presents a new method for robust voiced/unvoiced segment (V/UV) classification and accurate fundamental frequency ( ) estimation in a noisy environment. For this purpose, we introduce the degree of dominance and dominance spectrum that are defined by instantaneous frequency. The degree of dominance allows us to evaluate the magnitude of individual harmonic components of speech signal...
