In this paper an adaptive evolutionary algorithm (AEA) for high-level synthesis, resulting in reduction of the power dissipation in CMOS circuits is presented. It enables us to design contemporary electronic circuits/systems with minimisation of the peak and average power consumption, which leads to reduction of the peak and average temperature of the designed chip. Therefore, the reliability o...

This paper describes the phase-transition energies from published loading curves on basis of physically deduced FN = k-h3/2 law that does not violate energy by assuming h2 instead, as still do ISO-ASTM 14,577 standards. is valid for all materials and “one-point indentation” temperatures. It detects initial surface effects kink-unsteadiness. Why important? The mechanically induced phase-transiti...

Ultra-fine grained (UFG) structure (~0.6 µm) was produced in the stir zone (SZ) of 6061-T6 aluminum alloy joints using friction stir processing (FSP) cooled by liquid nitrogen (N2). A new experimental set-up was used to simultaneously quench the lower and upper surfaces of the samples during the processing. In addition, FSPed joints, using a steel backing plate, were produced at room temperatur...
