In human voices, low fundamental frequency is thought to be a cue to masculinity and reproductive capability and large vocal tracts are associated with large body size of the speaker. Female preferences for males with low fundamental frequencies and large vocal tract lengths are potentially adaptive. Although sexually dimorphic characteristics of male voices have been studied, the impact of man...
in this paper, a new analytical method is proposed to study the effect of crack and axial load on vibration behavior and stability of the cracked columns. using the local flexibility model, the crack has been simulated by a torsional spring with connecting two segments of column in crack location. by solving governing eigenvalue equation, the effect of crack parameters and axial load on the nat...
Introduction. Amidst the multiplicity of audio signal processing tasks connected with necessity source separation, problem obtaining its most prominent components occupies special place. One approaches, dedicated to solve such task, is based on melody extraction from musical recording. If generalized, technique can be applied a wider class signals for them so-called fundamental frequencies cont...
In this paper an effective method for the purpose of state estimation of fundamental and harmonics signals in the radial power distribution network is presented. In Addition, the application development of this method to the network observability and data processing is considered and analyzed. One of the most advantages of this method is capability of bad data detection and process of them and ...
