13. AN ANALYTICAL METHOD FOR THE HARMONIC ANALYSIS OF SATURATED REACTORS / UM MÉTODO ANALÍTICO PARA ANÁLISE HARMÔNICA DE REATORES SATURADOS
This work is concerned with the presentation of an analytical method for the harmonic analysis of three-phase saturated reactors when used for controlling voltage in power systems. The requirements for voltage control in transmission and distribution systems through the demand for reactive power are first discussed and the various types of existing compensat

14. Mice and humans perceive multiharmonic communication sounds in the same way
Vowels and voiced consonants of human speech and most mammalian vocalizations consist of harmonically structured sounds. The frequency contours of formants in the sounds determine their spectral shape and timbre and carry, in human speech, important phonetic and prosodic information to be communicated. Steady-state partitions of vowels are discriminated
