AbstractIn this paper we formulate Stein–minimax type estimators and compare the performance properties with other estimators in case of mean value predictions. When the model is estimated by ordinary least squares it has been observed that least squares predicted is unbiased while minimax and Stein-minimax predictors are biased. The superiority conditions of the estimators have been derived by...

AbstractIn this paper, a novel functional network designing method based on cultural algorithm is proposed. This method can get the hybrid basis function and its parameters with optimal searching achieving the learning between functional network structure and the functional parameters, and each model of the initial set is evaluated by the adjusted  R squared criterion ) ( 2 a R , to find the o...

AbstractIn this paper, an efficient simulation model for fuzzy logic controlled brushless direct current motor drives using Matlab/Simulink is presented. The brushless direct current (BLDC) motor is efficiently controlled by Fuzzy logic controller (FLC). The control algorithms, fuzzy logic and PID are compared. Also, the dynamic characteristics of the BLDC motor (i.e. speed and torque) and as w...

OBJECTIVE To describe the behavior of mortality in Mexico through four indicators from 1990 to 2012. MATERIAL AND METHODS The official mortality and population records of Mexico were used. RESULTS An advance was achieved for children under five years of age, with a decrease in mortality, although there was an increase in the years of potential life lost (YPLL) from 2008 for this age group. ...

AbstractIn the last decades, study of normative conflicts in deontic logic has been guided by two main issues: first, developing conflict tolerant systems, typically
