This work proposes a structural enhancement and new technique to design the loop filter (LF) of third-order phase-locked (PLL) enhance PLL dynamic performance under abnormal grid conditions. The proposed combines moving average (MAF) an arbitrarily delayed signal cancelation (ADSC) for achieve DC-offset rejection harmonics elimination. window length MAF is selected be one-sixth fundamental peri...

OBJECTIVE Traditional electroencephalogram (EEG) recorders reject low frequencies and DC and therefore cannot handle fullband EEG. Dedicated fullband recorders use non-standard file formats, because the standard format (EDF) cannot handle large DC electrode offset voltages. Both facts limit the development and use of fullband EEG. We developed a modification that allows conventional equipment t...

The presence of the DC components in grid voltage adversely affects performance synchronization unit, causing oscillatory and offset errors estimated information. Several approaches were proposed to address problem by incorporating an additional filtering stage synchronous reference frame phase-locked loop (SRF-PLL). Removing using modified delayed signal cancelation (MDSC) operator inner SRF-P...

Since the fabrication of active electrodes has been reported and their beneficial effects scientifically confirmed, we present a CMOS bioelectric amplifier with DC rejection designed for active electrode in this paper. Analysis, design and post simulation results will be described in detail. The amplifier operating at ±0.9V supply voltage has a mid-band gain of 40dB with ±300mV dc offset reject...

In this paper a general formulation for finding the maximum allowable dynamic load (MADL) of flexible link mobile manipulators is presented. The main constraints used for the algorithm presented are the actuator torque capacity and the limited error bound for the end-effector during motion on the given trajectory. The precision constraint is taken into account with two boundary lines in plane w...

We consider wavelength-selective splitting of radiation using directional couplers (DCs) formed by dielectric-loaded surface-plasmon-polariton waveguides (DLSPPWs). The DCs were fabricated by depositing sub-wavelength-sized polymer ridges on a gold film using large-scale UV photolithography and characterized at telecommunications wavelengths with near-field microscopy. We demonstrate a DLSPPW-b...

Grid connected static power converters inject parasitic DC currents due to the offset in current sensing, control imperfections, asymmetries in power switches and other secondary effects. Ever growing number of grid connected converters contributes to an increase of DC bias in AC grids, and this brings the cores of distribution transformers closer to saturation and increases their power losses....

Suppression of tumor metastasis is a key strategy for successful cancer interventions. Previous studies indicated that rapamycin (sirolimus) may promote tumor regression activity or enhance immune response against tumor targets. However, rapamycin also exhibits immunosuppressant effects and is hence used clinically as an organ transplantation drug. We hypothesized that the immunosuppressive act...
