In time-distance helioseismology, wave travel times are measured from the cross-correlation between Doppler velocities recorded at any two locations on the solar surface. However, one of the main uncertainties associated with such measurements is how to interpret observations made in regions of strong magnetic field. Isolating the effects of the magnetic field from thermal or soundspeed perturb...

A run-time reconfigurable multiply-accumulate (MAC) architecture is introduced. It can be easily reconfigured to trade bitwidth for array size (thus maximizing the utilization of available hardware); process signed-magnitude, unsigned or 2’s complement data; make use of part of its structure or adapt its structure based on the specified throughput requirements and the anticipated computational ...

Purpose The purpose of this paper is to examine mothers’ social media accounts that focus on children’s fashion. authors probed fashion photo practices as representations the extended self and kind childhood produced by accounts. They also investigated perceptions privacy when engaging in sharenting – sharing information about children or parenting online. Design/methodology/approach study base...

The ultrasonic velocity (V), density (ρ) and viscosity (η) measurements of Hydroquinone in n-propanol and iso-propanol have been carried out for the study of solute-solvent interaction. Experimental data have been used to calculate the isentropic compressibility (bs), intermolecular free length (Lf), specific acoustic impedance (Z), molar sound velocity (R), relative association (RA) solvation ...

This paper is devoted to the design of a 258bit multiplier for computing pairings over Barreto-Naehrig (BN) curves at 128-bit security level. The proposed design is optimized for Xilinx field programmable gate array (FPGA). Each 258-bit integer is represented as a polynomial with five, 65 bit signed integer, coefficients . Exploiting this splitting we designed a pipelined 65-bit multiplier base...
