Due to widespread use of Global Positioning System (GPS) in different applications, the issue of GPS signal interference cancelation is becoming an increasing concern. One of the most important intentional interferences is spoofing signals. An effective interference (delay spoof) reduction method based on adaptive filtering is developed in this paper. The principle of method is using adaptive f...

Harmonic identification by using Adaptive Tabu Search (ATS) Method embedded in the active power filter is proposed in this paper. The use of the ATS identifies harmonic components more accurately and precisely. Besides the accuracy and precision, it is able to select only some particular harmonic orders that cause severe consequences to the system for elimination. This principle thus leads to t...

The perfect linear phase requirement can be achieved only by direct design with an FIR filter at the expense of high filter order and hence high computational burden for the given specification. Alternatively, IIR filters can be designed with much smaller orders than their FIR counterparts, but at the expense of the nonlinear phase. However, it is possible to design almost linear-phase IIR filt...

we compare performance of adaptive schemes which are based on radial-basis functions and kalman filters for fast extraction of auditory evoked potentials. moreover, we propose a new method based on evoked potential modeling in the kalman filter framework, which can improve the accuracy compared to the existing methods. simulation results show that adaptive schemes and the kalman method are not ...

There is increased interest in the use of graphics processing units (GPUs) for general purpose computation. This is because GPUs are almost two orders of magnitude faster in terms of floating point throughput compared to conventional CPUs. In this paper we investigate the use of graphics processing units for accelerating signal processing algorithms, specifically FIR filters and the FFT. We des...

The main objective in this research is to explore two separate approaches for improving the growth of microalgae that can be potentially used for producing fuels and chemicals. One approach was to use optical light filters, which selectivity filter natural light allowing certain wavelengths into the culture systems. The other study is to use an algal growth system with different bio-renewable m...
