LC-coupling hybrid active power filter (LC-HAPF) is a cost-effective solution to address power quality issues in low and medium voltage distribution networks. The DC-link voltage controller plays an important role of the LC-HAPF performance. Conventionally, proportional-integral (PI) controller is commonly used for DC-link voltage control due to the ideally zero steady-state error. However, the property of integrator slows down the transient response of DC-link voltage and thus effects the LC-HAPF dynamic performance. In this paper, a nonlinear PID (NPID) controller based on robust exact differentiator (RED) is proposed to improve the transient response of conventional PI controller. First, the parameters of the PID controller are designed by s-domain transfer function analysis. Then, the RED is proposed to replace the linear differentiator, which provides the differential signal fast and accurately. Finally, the advantages of the proposed NPID controller based on RED are verified by simulation results compared with the conventional PI controller. © 2022 IEEE.

Multifractal characterization for classification of telecommunications traffic

Canadian Conference on electrical and computer engineering (CCECE)

A novel multifractal approach to telecommunications traffic classification is presented as an improvement over traditional traffic classifiers. The fundamental advantages of using multifractal measures include normalization and a very high compression ratio of a signature of the traffic, thus leading to more reliable and faster implementations, and the ability to add new traffic classes without redesigning the traffic classifier. The variance fractal dimension trajectory is used to provide a multifractal "signature" for each type of traffic over its duration. As a multifractal, the Renyi dimension spectrum is constructed to show the unique characteristics of each type of traffic. A probabilistic neural network is trained with the variance fractal dimension trajectory of the traffic, and has demonstrated 90.7% classification accuracy with a 585:1 compression ratio, and 90.4% classification accuracy with a 1024:1 compression ratio.

This paper presents a new application of independent component analysis (ICA) in magnetic resonance (MR) image analysis. One of most successful applications for ICA-based approaches in MR imaging is functional MRI (fMRI) which basically deals with one-dimensional temporal signals. The ICA approach proposed in this paper is rather different and considers a set of MR images acquired by different pulse sequences as a 3-dimensional image cube and performs image analysis rather than signal analysis. One major difference between the fMRI-based ICA approaches and our proposed ICA-based image analysis is that the ICA used in the former is under-complete as opposed to the latter which uses over-complete ICA. Such a fundamental difference results in completely different applications. © 2005 IEEE.

This paper formalizes the general theory of instantaneous heart-rate (IHR) interpolation from electrocardiogram RR-intervals. This paper also introduces a novel extension to the current basic piecewise-linear interpolation method which allows the discontinuity of the IHR interpolation to be offset from the R-wave. Thus an entire heart cycle can be modelled with a constant IHR. This phase-offset piecewise-linear IHR interpolation model is derivedfrom the general theory of IHR interpolation and results are demonstrated on some true recorded RR-sequences. Recursive and batch matrix forms are derived. Stable solutions can be found for any offset not equal to it radians, though the IHR calculated with a nonzero offset has a significant change to the HRV statistics. Applications of this method to the synthesis of ECG with natural heart-rate variability is also discussed.

Spectral measures have been used in material identification and discrimination. They are effective if the spectral signatures are calibrated and not contaminated. However, it may not be true in many real applications, specifically, for mixed pixels and subpixel targets. This paper investigates the issue of discrimination and identification for subpixel targets and further develops sample spectral covariance/correlation matrix-based hyperspectral measures to account for spectral variability within subpixel targets. Two types of measures are of interest and studied, Mahalanobis distance-based hyperspectral measures and matched filter-based hyperspectral measures. In order to substantiate the proposed measures, a real data-based comparative analysis is conducted and compared to two spectral similarity measures, spectral angle mapper (SAM) and spectral information divergence (SID) for performance evaluation. The experiments show that both Mahalanobis distance-based hyperspectral measures and matched filter-based hyperspectral measures work very effectively and outperformed the SAM and the SID in discrimination and identification for subpixel targets. ©2004 IEEE.

In this paper, effects of including the curvature of the Earth in the characterization of the lightning strike maps (LSMs) are studied. Lightning strikes can adversely affect the power generation and distribution systems, and behaviour prediction of such LSMs is of interest for protection and planning in the power industry. Characterization is one of the important stages of the behaviour prediction. We have shown that multifractal measures such as the Rényi fractal dimension spectrum (RS) are appropriate for characterization of such LSMs which are self-affine. The computation of the RS is based on estimating the probability density function (pdf) of the lightning strikes distribution. Since the LSMs range from very large to low densities over a large geographical area such as Manitoba, computing this pdf in planar coordinates is subject to a nonlinear error due to the curvature of the Earth. Thus, modelling and calculating the maps in spherical coordinates yields a better estimation of the pdf. The data of the LSMs have been collected by the Canadian Lightning Detection Network (CLDN) during the year 2002. The LSMs of Manitoba are characterized through regular (using planar coordinates) and modified (using spherical coordinates) RS techniques. The results indicate that regular RS technique alters the characteristics of the feature space, especially in latitudinal direction, and causes sparser features in the feature space, while using the modified RS technique alleviates all these problems, and provides a more accurate characterization which is necessary for a reliable classification of the maps. © 2005 IEEE.

This paper describes a unique cross-phoneme speaker identification experiment, using deliberately mismatched phoneme sets for training and testing. The underlying goal is to identify features that represent broad individually unique characteristics rather than those that represent phonetic differences, as are more typical of modern speaker identification and verification systems. A wide range of features are proposed and evaluated within this context using a Gaussian Mixture Model framework. The results show that log-area ratio has better phonetic independence than MFCCs, that residual phase carries substantial speaker information, and identifies several other features that also have usefulness for speaker identification independent of phonetic content.

Unlike MANET (Mobil Ad Hoc Network), VANETs (Vehicular Ad Hoc Networks) are characterized by an unlimited number of vehicles can be equal to millions of vehicles and a high mobility. The objective of developing VANETs is to improve ITS (Intelligent Transportation Systems) in terms of road safety and efficiency in the transport field. Traditional routing protocols (packet based) used for MANETs (Mobile Ad hoc Networks) does not satisfy the routing requirements in VANETs due to high speed of vehicles. In this work we propose a routing protocol with data aggregation for VANETs, where we invoke the based point geographic routing and data aggregation. The results of our simulation with SUMO and NS-3 show that our approach can help to reduce network overload by aggregating road traffic reports without maintaining a hierarchical structure. © 2021 IEEE.

The Discrete Fourier Transform (DFT) is a mathematical procedure that stands at the center of the processing that takes place inside a Digital signal Processor. It has been known and argued through the literatures that the Fast Fourier Transform (FFT) is useless in detecting a specific frequency in a monitored signal because most of the computed results are ignored. In this paper we will present an efficient FFT based method to detect specific frequencies in a monitored signal which is compared to the most frequently used method "the Goertzel's Algorithm". Parallel implementation structure show a fast computation method compared to the Goertzel's algorithm. Computational speedup gains of r using radix-r butterfly are shown. ©2010 IEEE.

This paper presents an ultra-low quiescent current output-capacitorless low dropout regulator (OCL-LDO) with fast transient response. We design a rail-to-rail error amplifier with improved adaptive biasing, which provides a limited bias current at heavy load for better load regulation. The buffer with adaptive biasing and almost zero input-output voltage shift and embedded body-bias, combines the error amplifier and the gate of MP. The proposed LDO is designed in a 65-nm CMOS process. Simulation result shows that the proposed LDO consumes a quiescent current of only 23 nA at a supply voltage of 0.8 V. The voltage undershoot is 98 mV during a 20-mA maximum load transient. And we obtain a FOMT of 0.00023 ps. © 2023 IEEE.
