Research ArticleOpen accessAll words, across the recordHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,818 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordDesign of a Merged DSP Microcontroller for Embedded Systems using Discrete Orthogonal TransformA. K. Rath, P. K. MeherIn this paper we have proposed the design of a DSP microcontroller where the processor load is significantly reduced by relegating the math-intensive DSP algorithm to dedicated transform computing modules. It is shown that the use of such transform modules will facilitate scalability, reusability and flexibility for implementation of wide varieties of DSP functionalities. Moreover, it would be possible to … …Journal of Computer Science, Vol. 2, Issue 5 · 31 Aug 2006 · 6,918 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordMulti-Controlled Wheelchair for Upper Extremities DisabilityChadi F. RimanPeople with motor disabilities are trying to be more autonomous by using an electric wheelchair with a conventional joystick control. However, a problem arises when these people are suffering from upper extremities disability such as tetraplegia. Several methods were implemented such as voice control, chin control, eye-blink, sip-and-puff, but each has its advantages and disadvantages. Furthermore, in some situations a … …Journal of Mechatronics and Robotics, Vol. 2, Issue 1 · 3 Dec 2018 · 7,244 accessesView PDFCite

A complete review regarding intelligent control design is presented in this study in order to show the most important artificial intelligence methods used for controlling an Inverted-Pendulum. Also this study proposed the use of a neural-fuzzy-with-genetic-algorithms controller for the inverted pendulum problem which gives … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 2 · 7 Apr 2014 · 8,379 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Novel µ-Negative Metamaterial With Enhanced Rejection BandwidthHaider Raad, Hussain Al-Rizzo, Ayman Abbosh, Said AbushamlehIn this study, a novel planar µ-Negative (MNG) metamaterial structure based on Split Ring Resonators (SRRs) with improved rejection bandwidth is presented. A bridging technique is used to connect two SRR unit cells at the center to emulate a cascaded filter. The proposed structure achieved a -20 dB rejection bandwidth of 15.5% compared to 4.5% for the conventional SRRs which … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 2 · 3 Apr 2013 · 7,372 accessesView PDFCite
