The aim of this study was to determine the effects of alpha neurofeedback and EMG biofeedback protocols for improvement of musical performance in violinists. The sample consisted of 12 music students (10 violinists and 2 viola players) from the Faculty of Music, Skopje (3 males, mean age of 20 +/- 0 and 9 females, mean age = 20.89 +/- 2.98). Six of them had a low alpha peak frequency (APF) (< 1...

Model predictive direct power control (MPDPC) strategy offers numerous benefits over the traditional strategies in active filters (APF). However, real-time execution duration (RTED) reduction of model multilevel inverters is a big challenge. In this paper, an improved low-computation for three-level four-leg APF (TL-FL-APF) presented. First, based on generalized instantaneous reactive theory, n...

Bootstrap particle filter as a subcase of APF Here we will show that when q is a delta function, APF recovers the bootstrap particle filter. The Dirac delta function can be considered as the limit of a Gaussian as the variance goes to zero, δ(θ − μ) = limσ2→0N (θ;μ, σ). Therefore, we can view q as an exponential family distribution. Specifically we are dealing with a Gaussian distribution with ...

This article offers a power quality (PQ) strategy to reduce light intensity flickers, voltage enhancements, and harmonics mitigation of the grid current in extensive networks LED lighting at Cairo airport, Egypt. A transformerless unified conditioner (TL-UPQC) with its controls is presented address majority PQ issues network. The TL-UPQC comprises dynamic restorer (DVR) as series compensator, w...

Abstract: Owing to the problems of DC side capacitor value choice in the application of Active Power Filter (APF), this article presents a technique based on the analysis of the ripple voltage in DC side by graining appropriately the undulation control rate within the range of settings and control DC voltage so that the voltage fluctuation rate can reach minimum value under the condition of spe...

This paper concentrates on compensating the power quality issues which have been increased in day-to-day life due to enormous usage of loads with electronic control. One such solution is devices like Pension Protection Fund (PPF), Active filter (APF), hybrid (HPF), etc., are used overcome Power Quality (PQ) issues. The proposed method here an active compensator called unified conditioner (UPQC)...

This paper proposes a preliminary design tool for active power filters’ (APFs) solutions to be applied in offshore oil and gas platforms, where quality indices are typically low, reactive compensation current harmonic mitigation often desired. The proposed approach considers that APF selection rating is trade-off between performance size, both component system aspects need optimized achieve wel...

Phase-locked loops (PLL) are widely used in the synchronization of grid interfaced power converters. One solution is based on orthogonal signal generation (OSG), which requires frequency information for their appropriate operation. This article developed a new to achieve PLL function single-phase interconnection but eradicate additional feedback traditional architecture all-pass filter (APF-PLL...
