Design of a new sense amplifier-based flip-flop (SAFF) using GDI Technique and performance comparison of proposed SAFF with existing conventional SAFF with CMOS-NAND latch SAFF and SAFF with CMOS Symmetric latch is presented in this paper. It was found that the main drawback of existing SAFF’s is the cross-coupled set-reset (SR) latch in the output stage. The new flip-flop uses a new output sta...

REACTIVITY OF N-SUBSTITUTED p-BENZO AND p-NAPHTHOQUINONEIMINE N-OXIDES TOWARD DIPOLAROPHILES

The dipolar cycloaddition reactivity of N-(1-naphthy1)-1,4- benzoquinoneimine N-oxide and N-phenyl-1,4- naphthoquinoneimine Noxide are investigated, The latter gives the expected adducts with common dipolarophiles such as acrylonitryle, methyl methacrylate, dimethylacetylene dicarboxylate and N-phenylmaleimide. The reactivity of the former nitrone is found to be minimal. It undergoes, how...

φ: P n �� � (P 1) n+1

We develop in this paper some methods for studying the implicitization problem for a rational map φ : Pn 99K (P1)n+1 defining a hypersurface in (P1)n+1, based on computing the determinant of a graded strand of a Koszul complex. We show that the classical study of Macaulay Resultants and Koszul complexes coincides, in this case, with the approach of approximation complexes and we study and give ...
