In this paper, an intelligent control method for the maximum power point tracking (MPPT) of a photovoltaic system under variable temperature and insolation conditions is discussed. The MPPT controller boost converter based on fuzzy logic (FLC) developed compared to conventional algorithm (P&O). different steps design these controllers are presented together with its simulation. Results simulation show that using increase efficiency energy production from PV.
Objective Cognitive impairment (CI) in systemic lupus erythematosus (SLE) is quite common and an important prognostic factor due to its severity. The aim of our study was determine the proportion type CI SLE identify associated risk factors. Methods We performed a cross-sectional (January - March 2022). Participants included patients controls (No-SLE). were subdivided into those with without defined based on results eight specific tests assessing various cognitive functions, MMSE used for...
This paper describes a new technique, called the empirical mode decomposition (EMD) that has recently been pioneered by N. E. Huang and al., for adaptively representing nonstationary signals as sums of zero-mean AM-FM components [N. Huang, et 1998]. The components, intrinsic functions (IMFs), allow analysis frequency composition one-dimensional signals. Applied to speech signal, EMD allows us study different oscillatory modes. Besides, computing LPC each provides an estimation formants....
This paper describes a multiscale product method (MPM) for open quotient measure in voiced speech. The is based on determining the glottal closing and opening instants. proposed approach consists of making products wavelet transform speech signal at different scales order to enhance edge detection parameter estimation. We show that effective robust detecting singularity. Accurate estimation instants (GCIs) (GOIs) important wide range processing tasks. In this paper, accurate GCIs GOIs used...
This paper deals with glottal parameter estimation such as local pitch and open quotient from electroglottographic signal (EGG). is based on closing instants opening determined by a multi-scale product of this signal. Wavelet transform EGG made quadratic spline function. coefficients calculated different dyadic scales, show modulus maxima at localized discontinuities The detected minima correspond to the called GOIs GCIs. To improve estimate precision, we operate wavelet three successive...
The authors present an algorithm for pitch estimation including voiced/unvoiced decision in the case of a noisy speech and when two speakers are talking simultaneously. approach is based on spectral multi-scale product (SMP) analysis sound mixture. SMP spectrum three successive wavelet transform coefficients speech. used quadratic spline function. proposed method compared with other state-of-the-art algorithms. It robust presence noise permits dominant concurrent one from mixture high accuracy.
