In this paper we investigate graph-based minimum-adder integer multipliers using carry-save adders. The previously proposed approaches use carry-propagation adders with two inputs and one output and are not suitable for carry-save adder implementation when we have a single input and a carry-save output of the multiplier. Using carry-save adders avoids carry propagation and will result in a high...

We discuss the scaling behaviour of different fermion actions in dynamical simulations of the 2-dimensional massive Schwinger model. We have chosen Wilson, hypercube, twisted mass and overlap fermion actions. As physical observables, the pion mass and the scalar condensate are computed for the above mentioned actions at a number of coupling values and fermion masses. We also discuss possibiliti...

Can tourism be the catalyst for urban preservation while permitting the continuation of urban culture? Only if local distinctiveness, rather than preserved monuments, is what attracts tourists to an historic region, argues Orba̧sli. The author advocates preservation through a planning-management approach. This approach avoids façadism (i.e., preservation of the physical elements only), and inste...

The application of frequency domain equalization techniques makes single carrier modulation a potentially valuable alternative to OFDM, especially in regard to its robustness to RF implementation impairments. In this overview paper we survey recent results on single carrier systems with frequency domain equalization (SC-FDE), including comparisons and compatibilities with OFDM, and extensions v...

In this manuscript novel architectures for modulo 2 þ 1 multi-operand addition and residue generation are introduced. The proposed arithmetic components consist of a translation stage, an inverted endaround-carry carry-save-adder tree and an enhanced diminished-1 modulo 2 þ 1 adder. Qualitative and quantitative results indicate that the proposed architectures result in significantly faster and ...
