in this paper a novel process monitoring scheme for reducing the type і and type іі error rates in the monitoring phase is proposed. first, the proposed approach uses an augmented data matrix to implement the process dynamic. then, we apply independent component analysis (ica) transformation to the augmented data matrix, and eliminate the outliers using the local outlier factor (lof) algorithm....

A stereo similarity function based on local multi-model monogenic image feature descriptors LMFD is proposed to match interest points and estimate disparity map for stereo images. Local multi-model monogenic image features include local orientation and instantaneous phase of the gray monogenic signal, local color phase of the color monogenic signal, and local mean colors in the multiscale color...

in this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave rof) system that uses a dual drive mach zehnder modulator (dd-mzm), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. the input to the dd-mzm are binary phase shift keying (bpsk), quadrature phase shift keying (qpsk), 8-phase shift keying (8-psk) and...

Weakly coupled phase oscillators and strongly coupled relaxation oscillators have different mechanisms for creating stable phase lags. Many oscillations in central pattern generators combine features of each type of coupling: local networks composed of strongly coupled relaxation oscillators are weakly coupled to similar local networks. This paper analyzes the phase lags produced by this combin...

A phase-locked-loop (PLL)-based frequency synthesizer incorporating a phase detector that operates on a windowing technique eliminates the need for a frequency divider. This new loop architecture is applied to generate the 1.573-GHz local oscillator (LO) for a Global Positioning System receiver. The LO circuits in the locked mode consume only 36 mW of the total 115-mW receiver power, as a resul...

A statistical distinguishability based on relative entropy characterizes the fitness of quantum states for phase estimation. This criterion is employed in the context of a Mach-Zehnder interferometer and used to interpolate between two regimes of local and global phase distinguishability. The scaling of distinguishability in these regimes with photon number is explored for various quantum state...

The performance of frequency domain differentially encoded quadrature phase shift keying (FDQPSK) 26 Mb/s orthogonal frequency division multiple access (OFDMA)-systems with respect to phase noise and time-variant frequency-selective fading is analyzed. FDQPSK completely eliminates the common phase error (CPE) when used in combination with a pilot carrier. Despite its higher sensitivity to inter...
