This paper proposes an ultra-compact filtering power divider with a wide harmonic suppression band. In this design, the proposed (PD) in ideal case has 100% size reduction and infinite number of harmonics suppression. However, real case, 92% suppresses 2nd to 45th harmonics. The small-proposed is designed at 0.9 GHz. typical Wilkinson two long quarter-wavelength branches. new resonant series LC...

Noise would give rise to incorrect filtering frequency-band selection in signal filtering-based methods including fast kurtogram, teager energy operators and wavelet packet transform filters meanwhile result of useful components even mode mixing, end effects, etc., decomposition-based empirical decomposition, singular value decomposition local mean decomposition. On the contrary, noise stochast...

We investigate the scale-shift operator for discrete-time signals via action of hyperbolic Blaschke group. Practical implementation issues are discussed and given any arbitrary scale, in framework very classical linear filtering. Our group theoretical standpoint leads to a purely harmonic analysis definition Mellin transform signals. Explicit analytical expressions atoms Fourier-Mellin decompos...

We investigate statistics of the photon (phonon) field undergoing linear and nonlinear damping processes. An effective two-photon "cooling by heating" process is realized from spectral filtering heat baths present in system. This cooling driven incoherent quantum thermal noise can create states field. In fact, for high temperatures spectrally filtered baths, sub-Poissonian with strong antibunch...

In this study, a novel wave processing algorithm: “local wave-direction estimation (LWDE)”, is proposed to localize sources of guided waves using full-field scanning laser Doppler (SLDV) measurements. The LWDE algorithm uses angular bandpass filters in the wavenumber domain determine local propagation direction wave. obtained map converted into an error by use virtual map. resulting reveals as ...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...

social networks play a significant role in today world. these sites affect different aspects of individual and social life of people and the national and even international levels. accordingly, they are spreading, and will play more important role in the future life. this paper aims to examine the positive and negative effects of social networks’ filtering, that creates curiosity and has invers...

spike sorting is a class of techniques used in the analysis of electrophysiological data. studying the dynamics of neural activity via electrical recording relies on the ability to detect and sort neural spikes recorded from a number of neurons by the same electrode. this article reviews methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting.

As an special intuitionistic fuzzy set defined on the real number set, triangular intuitionistic fuzzy number (TIFN) is a fundamental tool for quantifying an ill-known quantity. In order to model the decision maker's overall preference with mandatory requirements, it is necessary to develop some Bonferroni harmonic mean operators for TIFNs which can be used to effectively intergrate the informa...

Seasonal signals (annual plus semi-annual) in GPS time series are of great importance for understanding the evolution of regional mass, i.e. ice and hydrology. Conventionally these signals (annual and semi-annual) are derived by least-squares fitting of harmonic terms with a constant amplitude and phase. In reality, however, such seasonal signals are modulated, i.e. they will have a time-variab...
