Over the last decades, Morocco has been facing increasingly severe water scarcity. To quantify use in Morocco, we refer to footprint (WF) concept, including both direct and indirect use. WF considered covers internal exported virtual (VW). We used input-output structural decomposition analysis (SDA) quantitatively analyze drivers of changes Morocco’s sectoral from 1995 2015. The mechanisms gove...

We study neural networks whose only non-linear components are multipliers, to test a new training rule in a context where the precise representation of data is paramount. These networks are challenged to discover the rules of matrix multiplication, given many examples. By limiting the number of multipliers, the network is forced to discover the Strassen multiplication rules. This is the mathema...

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...

Low-cost finite impulse response (FIR) esigns are presented using the concept of faithfully rounded truncated multipliers. We jointly consider the optimization of bit width and hardware resources without sacrificing the frequency response and output signal precision. Non-uniform coefficient quantization with proper filter order is proposed to minimize total area cost. Multiple constant multipli...

This contribution describes new GF (p) multipliers, for p > 2, specially suited for GF (p) multiplication. We construct truth tables whose inputs are the bits of the multiplicand and multiplier and whose output are the bits that represent the modular product. However, contrary to previous approaches, we don’t represent the elements of GF (p) in the normal binary positional system. Rather, we ch...

This paper proposes that several FFT algorithms such as radix2, radix-4 and split radix were designed using VHDL with the multiplication complexity reduced more than 30% by using the newly proposed CSD constant multipliers instead of the programmable multipliers and the simulations of standard 0.35 μm. The sizes of FFT/IFFT operations are varied in different applications of OFDM systems. The re...

this paper has used a multisectoral input-output model of iranian economy to examine the ability of different sectors of economy to create jobs per unit of output as well as capital. the results reveal that there is no conflict in a growth strategy that simultaneously attempts to improve efficiency i.e. reallocating production to sectors with low drcs, equity and job creation. although sectoral...
