improve the power quality. In this paper the Forgetting Factor RLS (FFRLS) approach has been considered to estimate not only voltage sag‚swell‚momentary interruption but also the amplitudes and phases of harmonics in case of time varying power signals in presence of White Gaussian Noise. Also comparison results with LMS and NLMS algorithms are presented to show the effectiveness of the proposed RLS algorithm. Keywords- RLS‚ LMS‚ NLMS‚ Harmonic Estimation‚ White Gaussian Noise I.

noise and distortion encountered when communicating over AC power wiring. Various technologies which have been used to address these challenges‚ such as spread spectrum and digital signal processing‚ are then examined in light of the known channel conditions. Introduction While the idea of sending communication signals on the same pair of wires as are used for power distribution is as old as the telegraph itself‚ the number of communication devices installed on dedicated wiring far exceeds the

She has consistently performed well and stands within the top 5 in her class of 66. She has a good understanding of the fundamentals in these subjects which will help her a great deal in furthering her skills during the graduate studies in her proposed field of communications and signal processing She is articulate and can express herself

is implemented by modern hardware ICs and simple sensor circuit with software executable on both PC and Android platform. The biosignal is first extracted via photoplethysmography (PPG) principle into electric signal. Then a microprocessor is used to covert biosignal from analog to digital format‚ suitably for feeding into an RF module (nRF24L01 for RF transmission). On the receiver end‚ the computer and/or smart phone can analyze the data using a robust algorithm that can detect peaks of the

currently it is not a difficult task to spread digital multimedia over Internet. This makes the protections of digital intellectual property rights and content authentications have been a serious problem. Hence the technology of digital watermarking is received a large deal of attention. Generally‚ digital watermarking techniques are based on either spread spectrum methods or changing the least significant bits of selected coefficients of a certain signal transform. For speech watermarking‚ to ensure

effective method to enable comparison and analysis of such data. The aim of image fusion‚ apart from reducing the amount of data‚ is to create new images that are more suitable for the purposes of human/machine perception‚ and for further image-processing tasks such as segmentation‚ object detection or target recognition in applications such as remote sensing and medical imaging. For example‚ visible-band and infrared images may be fused to aid pilots landing aircraft in poor visibility. Multi-sensor

was to shift from analog to digital electronics by purchasing digital components from an outside vendor. Since this was the industry trend‚ it would only be logical for all the divisions within the company to readily accept the project. Unfortunately for Monica‚ this was not the case. Monica faced strong opposition by Ralph Parker‚ the VP for Signal Processing Design. Parker had three important sources of power: legitimate‚ expert and coercive. As VP of Signal Processing‚ Parker’s power was legitimate:
