This Paper deals with digital simulation of FC-TCR, which can enhance the Power Quality of a power system. Reactive power is controlled by using tapped inductor system. This system reduces THD in the line current. Smooth variation of reactive power can be obtained by varying the firing angle of TCR. This circuit eliminates switching transients and improves the life of the capacitors. The simula...

In this paper, an optimal approach to design wideband Tapped-Delay Line(TDL) array antenna is proposed. This approach lets us control the array angular and frequency response over a wide frequency band. To this end, some design restrictions are defined and a multi-objective optimization problem is constructed by putting the individual restrictions together. The optimal weights of the TDL proces...

We investigate the performance of uncoded uplink transmissions in a broadband code division multiple access (CDMA) system using a tapped delay line (TDL) antenna array. First, the weights of a TDL antenna array are derived for broadband CDMA. Using these weights, we perform simulations to demonstration how TDL antenna arrays can help reduce multi-access interference (MAI), allow the use of spre...

Query by tapping remains an intuitive yet underdeveloped form of content-based querying. Tapping databases suffer from small size and often lack useful annotations about users and query cues. More broadly, tapped representations of music are inherently lossy, as they lack pitch information. To address these issues, we publish QBT-Extended—an annotated dataset of over 3,300 tapped queries of pop...

A novel structure called tapped cascaded adap-tive allpass lter is proposed. It is basically an adaptive nite impulse response (AFIR) lter where the delays are replaced by allpass lters. The system induces a better stability monitoring mechanism than in a generic adaptive inn-nite impulse (AIIR) lter. Two adaptation algorithms are derived. The rst one is for adapting the tap-weights when the al...

Generally, bipolar transistors have better performance than MOS transistors if higher transconductances for the same operating point or higher transition frequencies are required. On the other hand, compared to MOS transistors, bipolar transistors often have limited use in the design of VCO’s, due to a limited voltage swing across the resonator and therefore limited phase-noise performance. How...

K-12 education reform research suggests that new models of teacher professional development (TPD) are needed to establish and support communities of teachers engaged in school reform. We are working with several TPD organizations to develop a new on-line TPD community concept called TAPPED IN. Together, we are forging what we believe will be a self-sustaining TPD community in an on-line environ...
