Metamodeling, i.e. building surrogate models to expensive blackbox functions, is an interesting way to reduce the computational burden for optimization purpose. Kriging is a popular metamodel based on Gaussian Process theory, whose statistical properties have been exploited to build efficient global optimization algorithms. Single and multi-objective extensions have been proposed to deal with c...

a multi objective honey bee mating optimization (hbmo) designed by online learning mechanism is proposed in this paper to optimize the double fuzzy-lead-lag (fll) stabilizer parameters in order to improve low-frequency oscillations in a multi machine power system. the proposed double fll stabilizer consists of a low pass filter and two fuzzy logic controllers whose parameters can be set by the ...

This article presents an in-depth case study analysis of a single rural telecentre located in the Western Cape Province of South Africa. The study embraces the sociotechnical research paradigm and uses a combination of hermeneutics and actor-network theory as the theoretical foundation with which to explore the mutual interaction between people and ICTs. The objective of the analysis is to gain...
