Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...

A compact and low-power design of a 12-bit binary-weighted current-steering DAC is presented. Instead of 4096 unit current cells, the proposed design uses 192 unit current sources with two reference currents. The silicon area of the generation circuit of two reference currents is very compact as well. The area of the total current source arrays is smaller than four times the area of 6-bit curre...

This research studies the generation gap among the students at Andimeshk Islamic Azad University. More than 305 people were chosen by Cochran Formula in the study. The dependent variable was divided to four dimensions social, cultural, political and economic. The obtained mean of the study shows there is a meaningful difference between students and their parents (fathers and mothers). It also s...

This paper proposes a low voltage CMOS nano-ampere current reference circuit and presents its performance with circuit simulations in 180-nm technology. The proposed circuit consists of biasvoltage, current-source and offset-voltage sub-circuits with most of MOSFETs operating in subthreshold region. Simulation results show that the circuit generates a stable reference current of 110-nA in suppl...

This paper presents a novel fuzzy control scheme applied to shunt active power filters for harmonic and reactive power compensation. A TSK type fuzzy logic controller is proposed for APF reference current generation. To control the maximum switching frequency of the converter within limit a novel fuzzy hysteresis band current controller is used. The band height, based on fuzzy control principle...

in this paper, the impacts of installing superconducting fault current limiter (sfcl)in radial and loop power distribution system are evaluated to improve voltage sag in both cases of with and without distributed generations (dg). among various sfcls, the hybrid type with a superconducting element in parallel with a current limiting reactor (clr) is selected. this is more effective than resisto...

The work reported in this paper started out as an investigation of the use of perfects in news items taken from newspapers in different European languages. The original goal was to see if one could identify anything like the "hot news" use of the perfect, as defined by McCawley (1971). To this end, we excerpted in a number of European languages with perfects or perfect-like categories the first...
