Computationally expensive models are increasingly employed in the design process of engineering products and systems. Robust particular aims to obtain designs that exhibit near-optimal performance low variability under uncertainty. Surrogate often imitate behaviour computational models. Surrogates trained from a reduced number samples model. A crucial component surrogate is quality training set...

Abstract Aiming at the constrained optimization problem where function evaluation is time-consuming, this paper proposed a novel algorithm called data-driven Harris Hawks (DHHCO). In DHHCO, Kriging models are utilized to prospect potentially optimal areas by leveraging computationally expensive historical data during optimization. Three powerful strategies are, respectively, embedded into diffe...

ground penetration radar (gpr) as a nondestructive method for identifying underground objects has been successfully applied to different fields of science such as geotechnical investigations, oil and gas exploration, geology, pipe detection and archeology investigations. metallic and nonmetallic objects can be identified by this method.  the depth of penetration is dictated by the gpr antennas....

We propose a fast, standard-compliant realization of the computationally expensive renormalization part of binary arithmetic coding in H.264/MPEG4-AVC. Our technique allows to replace time-consuming, bitwise-operating input and output as well as bitwise carry-over handling in a conventional implementation with corresponding routines operating in units of multiple bits. Experimental results demo...
