Efficient iterative methods are described for designing orthogonal and biorthogonal two-channel perfect-reconstruction FIR filter banks in such a way that for the analysis and the synthesis lowpass filter the number of zeros at z = −1 are fixed and the energies in the given filter stopband regions are minimized. The regularity of the analysis and the synthesis filter banks resulting when using ...

in this study the catalytic dehydrogenation of ethylbenzene to styrene was investigated in a simulated tubular sodalite membrane reactor. the high quality microporous sodalite membrane was synthesized by direct hydrothermal method and characterized by single gas permeation measurements. the performance of the prepared membrane showed high potential for application in a dehydrogenation membrane ...

Reactive power plays an important role in supporting real power transmission, maintaining system voltages within proper limits and overall system reliability. In this paper, the production cost of reactive power, cost of the system transmission loss, investment cost of capacitor banks and absolute value of total voltage deviation (TVD) are included into the objective function of the power flow ...

In modern digital protection and control systems, an alienation technique has recently become the workhorse of quantitative research and analysis. In this paper, an alienation technique is developed for calculations of original power factor on-line, active and compensation reactive powers and determination of the required number of capacitor banks to get the desired power factor. Alienation coe...

This paper presents a piezoelectric energy harvesting system demonstrating the output power enhancement when using a CMOS integrated pulsed-resonance converter (PRC) instead of a simple Schottky diode bridge rectifier. The combination of a storage capacitor, a blinking light emitting diode (LED) and a voltage detector forms a fixed voltage regulator and visualizes the output power extracted out...

An enzyme immobilization technique has been developed to determine the concentration of biological compounds. This technique has been applied to penicillinase and urease, which are crosslinked as very fine films directly onto the sensitive ends of pH glass electrodes, thereby dispensing with the need of an on-line enzyme reactor. The biosensor is incorporated in an FIA system within a magnetica...

.Abstract: In modern digital protection and control systems, a correlation technique has recently become the workhorse of quantitative research and analysis. In this paper, a correlation technique is developed for calculation of original power factor on-line, active and compensation reactive powers and determination of the required number of capacitor banks to get the desired power factor.
