Abstract Electrostatic induction charge which generated by the coupling effect of hybrid electric field AC/DC cross line and metal object under transmission can cause different levels shock injury to human. In order find out distribution law reduce electrostatic induction, this paper set up shielding lines paralleled AC DC respectively on outside side conductors along diagonal parallelogram at ...

The antioxidant activities of Ulva faciata, Nizimuddinia zanardinii and Gracilaria corticata were investigated in Chabahar, Iran. Methanol extract and n-hexane, dichloromethane and ethylacetate fractions used for antioxidative properties test by the total antioxidative activity, 2,2-diphenyl-1-picryl-hydrazylhydrate (DPPH)  free radical scavenging activity, reduction power, metal chelating acti...

We measure the halo bispectrum covariance in a large set of N-body simulations and compare it with theoretical expectations. find correlation among (even mildly) squeezed configurations. A similarly can be found between triangles long-wavelength power spectrum. This shows that diagonal Gaussian contribution fails to describe, even approximately, full these cases. our numerical estimate model in...

Efficient reduction of monoand disubstituted norbornyl α-diketones with zinc in [bmimBF4]:[H2O] to afford the corresponding acyloins in excellent yields and diastereoselectivities is described. In case of the monosubstituted norbornyl α-diketones, very high regioselectivities ranging from 90:10 to 100:0, in favor of diastereomer possessing endohydroxyl diagonal to endo-substituent were observed.

We present RADAGRAD a simple and computationally efficient approximation to full-matrix ADAGRAD based on dimensionality reduction using the subsampled randomized Hadamard transform. RADAGRAD is able to capture correlations in the gradients and achieves a similar regret – in theory and empirically – to fullmatrix ADAGRAD but at a computational cost comparable to the diagonal variant.

The thought of the virtual synchronous generator (VSG) for controlling the grid-connected inverters and providing virtual inertia to the microgrid is emerging as a wide extension of the droop control, power coupling that always exists in the low-voltage microgrid, which may deteriorate the dynamic response and the stability of the system. In this paper, the principle of VSG control is introduce...
