Optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. The distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

there are numerous, often contradictory reports on the effect of growth hormone (gh) therapy on thyroid function. these reports prompted us to evaluate the impact of gh therapy on thyroid function in previously euthyroid children with gh deficiency. twenty five clinically and biochemically euthyroid children with gh deficiency were studied. a thyroid profile (t4, free t4, t3 and tsh) was perfor...

The existence of minimal degrees is investigated for several polynomial reducibilities. It is shown that no set has minimal degree with respect to polynomial many-one or Turing reducibility. This extends a result. of Ladner [L] whew reciirsive sets are considered. An "honest '' polynomial reducibility, < ; , is defined which is a strengthening of polynomial Turing reduc-ibility. We prove that n...

Sediment redox potentials (EH) at stations of different trophic status in the central Adriatic from 2001-2007 were investigated in this paper. For most part of the year at open sea and channel stations EH values were mainly positive (+150 to 0 mV), even to 10 cm sediment depth. Positive EH (absence of sulphate reduction with very low sulphide concentrations) at these stations is probably caused...

due to damaging effects of speckle noise to information of radar images, reduction of these effects has been considered by many researchers. we discussed speckle reduction of radar images based on curvelet transformation. more specifically we discussed the speckle reduction with emphasizing on preservation of the edges by hard thresholding of curvelet transformation. in this algorithm, first mu...

This brief introduces an original reduction method of resonance effect dispersion by using bandpass negative group delay (NGD) function. The transfer function (TF) is model lumped RLC circuit. canonical parameters NGD passive cell are innovatively formulated as a the specifications. developed feasibility validated with commercial tool frequency domain simulations. Proofs-of-concept constituted ...
