A hybrid search method based on Ant Colony Optimization for Continuous Domains ( ACO ) and the Nelder-Mead Simplex algorithm is proposed to calculate the stability margin of linear time-invariant time-delay systems. The effectiveness of the Nelder-Mead Simplex procedure is combined with the global search power of the ACO method to obtain the stability margin of linear timeinvariant time-delay s...

We propose an entirely novel family of score functions for blind signal separation BSS , based on the family of mixture generalized gamma density which includes generalized gamma, Weilbull, gamma, and Laplace and Gaussian probability density functions. To blindly extract the independent source signals, we resort to the FastICA approach, whilst to adaptively estimate the parameters of such score...

Mead su texto fundamental Espíritu, Sí Mismo y Sociedad (1973) La tesis fondo es esta distinción apunta, a vez, una forma realización individuo, gracias cual éste deviene como sujeto reconocido portador derechos todo comunidad pertenece (s...

Coordinating a group of robots to work in formation has been suggested for a number of tasks, such as urban searchand-rescue, traffic control, and harvesting solar energy. Algorithms for controlling robot formations have been inspired by biological and organizational systems. In our approach to robot formation control, each robot is treated like a cell in a cellular automaton, where local inter...

The effects of mead wort heat treatment on the mead fermentation process and antioxidant activity were tested. The experiment was conducted with the use of two different honeys (multiflorous and honeydew) collected from the Lower Silesia region (Poland). Heat treatment was performed with the use of a traditional technique (gently boiling), the more commonly used pasteurization, and without heat...
