Every time a local economy generates a new job by attracting a new business, additional jobs might also be created, mainly through increased demand for local goods and services. This positive effect on employment is partially offset by general equilibrium effects induced by changes in local wages and prices of local services. In this paper, I estimate the long-term employment multiplier at the ...

We observe that the range of p for Wolff’s inequality on plate decompositions of cone multipliers can be improved by using bilinear restriction techniques. This in turn is known to improve the range for sharp Lp results on cone multipliers, local smoothing for the wave equation, convolutions with radial kernels, Bergman projections in tubes over cones, averages over finite type curves in R3 and...

We describe how a simple way to split input operands allows for fast VLSI implementations of subquadratic GF (2)[x] Karatsuba-Ofman multipliers. The theoretical XOR gate delay of the resulting multipliers is reduced significantly. For example, it is reduced by about 33% and 25% for n = 2 and n = 3 (t > 1), respectively. To the best of our knowledge, this parameter has never been improved since ...

Presents the design of variable array multipliers using VHDL. Multipliers of various operand sizes for different target processes can be implemented using the proposed VHDL based approach. The multipliers will be testable with a constant number of test vectors irrespective of the operand word lengths. A fast test pattern generator is also developed for simulation of the multiplier designs and s...

Multipliers are frequently used in DSP, Image processing architectures and microprocessors. Fast Fourier Transform (FFT), Discrete Wavelet Transform(DWT) and auto-correlation are the few important areas where multipliers are mostly used. As switching and critical computations of a multiplier are high, compared to other datapath units of a processing architecture, design of low power, high speed...

Discrete Gabor multipliers are composed of rank one operators. We shall prove, in the case of rank one projection operators, that the generating operators for such multipliers are either Riesz bases (exact frames) or not frames for their closed linear spans. The same dichotomy conclusion is valid for general rank one operators under mild and natural conditions. This is relevant since discrete G...
