A Data Acquisition USB Device has been designed, developed, realized and characterized to be used in Power Quality monitoring activities. The system simultaneously manage 8 data acquisition channels to allow acquisition on tri-phases plus neutral lines working at 499 samples per 50 Hz period. It can get external certified time and voltage references to warranty certified measurements. The syste...

Abstract: This paper puts forward a new method based on Hilbert-Huang Transform (HHT) and Wavelet denoising for extracting feature information of voltage flicker signal. Firstly, envelope signal could be extracted by using HHT from original signal containing noises. Then the noises and higher harmonic components of envelope signal could be removed by using Wavelet denoising. Finally, the noise-...

Software defined radar (SDR) is a multi-purpose radar system where most of the hardware processing is performed by software. This paper introduces a concept and technology trends of software defined radar, and addresses the advantages and limitations of the current SDR radar systems. For the advanced SDR concept, the KAU SDR Model (KSM) is presented for the multimode and multiband radar system ...

The boiler drum level control unit is one of the main parameter in the thermal power station. Currently the boiler drum parameters are monitored only by using MATLAB software. There is no automatic control available. In the proposed system the boiler drum parameters such as temperature level, pressure level, water level and Droplet identifier are measured and controlled by using embedded proces...

In the fall and spring of 2007 freshmen CS, CPE, and EE students, at Virginia Tech, had the unique experience of working with five or six programming languages, all within one year and all for the purpose of developing fundamental programming skills. One of those languages was purely educational in nature (Alice), three were traditional and text-based (C++, Java, and MATLAB script), but two wer...

MHEG represents a new multimedia and hypermedia standard proposed by ISO/IEC. This paper presents a new software authoring environment based around MHEG-5 that offers users a vehicle for creating multimedia applications that can interact with external programs which involve intense computational tasks. MEMIS provides a linkage between a multimedia frontend and externally available computational...

Biomedical measuring system for acquisition, processing and evaluation of ECG signal, blood and perfusion pressure and drug dosage is introduced. Mentioned signals are obtained during experiments on small animal hearts making use of a Langendorff setup. The USB powered system is conceived as a virtual instrument with an external measuring unit controlled by a microprocessor and connected to a h...

This paper presents an on-line nonlinear trajectory tracking control algorithm for differential wheeled mobile robot using optimal back-stepping technique based particle swarm optimization while following a pre-defined continuous path. The aim of the proposed feedback nonlinear kinematic controller is to find the optimal velocity control action for the real mobile robot. The particle swarm opti...

This study deals with one of frequently encountered tasks in process industry – accurate water level control. Proportional Integral Derivative (PID) control is often used for this purpose. Since control parameters of PID controller are fixed and tank system is inherently nonlinear, PID controller should not be used on wider level range. Therefore this study analyzes the effectiveness of water l...

A hearing screening test is a method to determine human ear disorders and conventional audiometers and audiologists are required to perform the test. However, this procedure is difficult to implement, especially in a remote site such as a factory or a school due to the ambient noise that may cause test inaccuracy. In this work, the application of active noise control (ANC) is proposed to reduce...
